PREFACE 

The  articles  manufactured  by  this  Company  are  quoted  at  prices 
consistent  with  their  quality  of  workmanship  and  material.  We  en- 
deavor to  place  hefore  the  public  the  very  best  that  can  be  produced 
or  obtained,  without  imitating  in  shape  Or  design  the  products  of  other 
makers.  All  our  articles  are  of  the  most  recent  standard,  with  every 
known  improvement. 

The  Lietz  instruments  are  well  known  to  the  profession,  having 
been  made  under  the  personal  supervision  of  our  Mr.  Lietz  since  1882  ; 
and  with  our  new  buildings  and  the  latest  improved  machinery,  de- 
signed to  meet  our  peculiar  methods  of  obtaining  the  highest  results, 
we  are  producing  goods  of  efficiency  at  most  moderate  prices. 

It  has  always  been  our  endeavor  to  produce  articles  of  merit  and 
for  this  reason  we  cannot  contend  that  our  goods  are  cheap.  Likewise 
our  line  of  equipment  and  supplies  has  been  selected  with  due  regard 
to  their  merit  and  the  satisfaction  to  be  obtained  through  their  use. 

We  make  a  large  variety  of  instruments,  each  of  which  is  con- 
structed with  special  regard  to  the  class  of  work  for  which  it  is  in- 
tended. Therefore  we  offer  a  full  assortment  from  which  the  most 
exacting  can  feel  assured  of  the  highest  satisfaction. 

Our  instruments  are  made  primarily  to  use.  Our  guarantee  means 
that  they  will  wear  many  years  if  properly  cared  for,  barring  accidents, 
of  course.  Many  of  our  earliest  products  are  today  doing  service  in 
the  field. 

We  respectfully  solicit  a  continuance  of  the  esteemed  patronage  of 
our  many  friends  and  hope  to  merit  it  through  consistent  care  and  at- 
tention to  the  details  of  the  demands  which  may  be  placed  upon  us.

THE  LIETZ  INSTRUMENTS 

Including  Remarks  on  their  Use,  Handling,  Care, 
Preservation  and  Adjustments. 


THE  ENGINEERS'  TRANSIT  OR 
THEODOLITE 

In  reviewing  the  different  parts  of  the  transit  and  theodolite,  it 
will  answer  our  purpose  to  include  them,  for  the  present,  under  one 
head,  using  both  terms  as  synonymous — the  word  theodolite  having 
been  defined  as  an  instrument  of  angular  measure,  possessing  two 
graduated  circles,  normal  to  each  other,  which  during  manipulation 
are  set  in  horizontal  and  vertical  planes  respectively.  Authorities  say 
that  it  is  generally  believed  that  the  word  theodolite  (theodolith)  is  a 
combination  of  Oca  sight,  080s  road,  and  Aiffos  stone  and  that 
in  order  to  understand  this  derivation  it  must  be  known  that  formerly 
all  supports  upon  which  theodolites  were  placed  were  made  of  stone. 
This  meaning,  however,  seems  somewhat  ambiguous,  and  other  deri- 
vations have  been  sought.    The  etymology  of  the  word  is  uncertain. 

In  classifying  there  appear  two  distinct  groups  of  theodolites :  the 
simple  theodolite,  in  which  the  lower  clamp  and  tangential  movement 
is  neglected;  and  the  repeating  theodolite,  possessing  the  double  hori- 
zontal movement  on  spindle  and  plate,  which  is  the  principal  feature 
of  all  complete  field  instruments  made  for  the  engineer  at  the  present 
time. 

The  various  parts  of  the  transit  or  theodolite  may  be  grouped 
under  the  following  heads,  viz. : 

Begipning  from  the  base-plate  we  have : 

1 — The  tripod  connection  with  the  leveling,  plumbing  and  center- 
ing apparatus  (Page  14)  ; 

2 — The  centers  (Page  17) ; 

3 — The  graduated  plate  and  verniers  (Page  17)  ; 

4 — The  compass  and  variation  plate  ( Page  20)  ; 

5 — The  standards  with  the  vertical  arc  and  its  movements  (Page

1.   The  Tripod  Connection 

An  important  feature  of  the  Lietz  precision-class  instruments  is 
that  they  are  attached  to  the  tripod  by  a  friction  coupling. 

It  has  been  customary  to  accomplish  this,  heretofore,  in  two  differ- 
ent ways.  One  is  to  attach  the  instrument  to  the  tripod  by  means  of 
a  screw  at  the  base-plate,  whereby  it  remains  complete  in  all  its  parts 
and  is  never  separated  above  the  leveling  screws.  This  is  the  method 
employed  by  the  best  makers,  but  it  is  somewhat  tedious  and  unsafe, 
as  every  engineer  has  had  occasion  to  find  out.  It  is  often  the  case 
that  the  screw  will  not  catch,  and  there  is  always  a  loss  of  time  and 
patience  in  trying  to  enter  the  thread  properly.  Another  point  is  that 
while  turning  it  on,  the  entire  weight  of  the  instrument  rests  upon  the 
screw  thread,  with  a  constant  tendency  to  wear  it  away. 

The  second  method  of  fastening  the  transit  to  the  tripod  is  by 
means  of  the  center,  making  it  attachable  or  detachable  above  the 
leveling  screws.  In  most  cases  the  foot  screws  may  also  be  turned 
from  the  tripod  head,  but  it  is  not  unusual  to  have  them  remain  as  a 
fixed  part  of  it.  This  mode  of  coupling  seems  to  us  very  defective. 
The  exposed  center  is  liable  to  injury  in  many  ways.  Dust  particles 
accumulate,  and  it  moves  with  difficulty  in  consequence,  if  it  does  not 
cause  fretting.  But  its  greatest  fault  is  the  incumbent  necessity  of 
providing  for  it  what  is  called  the  flat  center,  for  turning  the  upper 
plate.  In  such  an  instrument  the  plates  stand  too  high  above  the  level- 
ing screws,  which  causes  unsteadiness.  We  believe  it  to  be  very 
difficult,  if  not  impossible,  to  do  accurate  work  with  such  an  instru- 
ment. 

These  substantial  reasons  caused  Mr.  Lietz  to  invent  the  tripod 
coupling,  which  is  regarded  as  the  most  successful  innovation  by  all 
who  have  had  occasion  to  use  it. 

Figure  I  fully  illustrates  this  simple  but  most  effectual  device. 
On  the  tripod  head,  instead  of  the  ordinary  screw,  there  are 
three  jaws.  The  base-plate  of  the  instrument  is  swallowtail-shaped  on 
the  inside  (as  shown  at  F),  the  head  having  a  spring  bolt  C*.  The 
coupling  of  the  two  is  done  by  letting  one  of  the  grooves  on  the 
base-plate  meet  any  one  of  the  jaws  on  the  tripod  head,  when  one- 
third  of  a  revolution  to  the  right  will  make  the  connection ;  at  the 
same  instant  the  spring  C  will  fall  into  a  hole  in  the  base-plate,  which 
thus  prevents  any  possible  disconnection;  the  latter  is  effected  by  lift- 

*  The  spring  C  in  the  latest  construction  is  now  placed  on  the  tripod  head,  between  the 
lugs.    See  illustration,  page  98.

ing  the  spring  C  and  turning  to  the  left.  If  the  tripod  head  should 
have  been  worn  or  bent  by  accident,  the  movable  jaw  D,  which  is 
worked  by  the  side-screw  E  (with  a  large  adjusting  pin),  will  again 
give  the  coupling  friction  enough  to  hold  the  instrument  perfectly  firm 
on  the  tripod.

LIETZ   LEVELING   HEAD 

Quick  leveling  head  attachment. 

Price,  extra,  $20.00. 


The  chief  merit  of  our  arrangement  is  that  it  enables  one  to  attach 
or  detach  the  instrument  to  or  from  its  tripod  more  rapidly,  firmly  and 
safely  than  by  any  other  device  so  far  known,  and  that,  too, 
without  dividing  the  instrument  proper  into  two  parts,  which  is 
always  injurious  to  its  accuracy  and  stability,  as  we  have  just  pointed 
out.  To  this  we  may  add  that  it  is  more  durable,  easier  to  keep  clean 
and  cannot  get  out  of  repair. 

The  movable  jaw,  once  set  for  the  instrument,  need  not  again  be 
interfered  with.  It  is  absolutely  needless  to  adjust  the  friction  every 
time  the  instrument  is  placed  on  the  tripod. 

We  feel  quite  confident  in  saying  that  every  engineer  who  has 
once  used  this  new  coupling  will  readily  detect  its  great  merits,  and 
will  never  be  without  it.  All  the  large-sized  transits  and  levels  of  the 
Lietz  make  fit  the  same  tripod  head,  and  are  instantly  adjusted. 

Leveling  Screws 
As  these  are  used  more  than'  any  other  part  of  the  instrument, 
it  is  evident  that  they  should  be  very  durable.    Those  of  the  Lietz

make  possess  a  very  deep  thread,  rounded  a  little  on  the  edge,  which 
insures  a  very  smooth  motion  and  greater  durability  than  sharp-edged 
threads.    The  screws  are  made  of  composition  metal. 

The  lower  construction  of  the  transit  is  made  with  the  view  of 
affording  the  greatest  steadiness  under  all  conditions.  For  that  rea- 
son the  leveling  screws  are  not  run  through  a  thin  metal  disc,  with  a 
common  nut  attached  for  their  operation,  but  an  extra  strong,  star- 
shaped  casting,  made  in  one  piece,  is  provided,  through  which  the 
screws  are  passed  and  in  which  they  operate. 

The  whole  construction  of  this  part  is  intended  to  insure  the  abso- 
lute steadiness  of  the  instrument,  and  to  give  it  rigidity  even  in  a 
strong  wind.  Any  other  construction,  with  a  light  disc  parallel  to  the 
base-plate,  cannot  afford  that  stability  which  a  first-class  transit  or  level 
should  possess ;  and,  since  this  is  one  of  the  prerequisites  of  an  instru- 
ment of  precision,  we  have  laid  particular  stress  upon  our  leveling 
arrangement,  which  is  of  the  most  approved  modern  design. 

For  instruments  of  the  greatest  precision,  as  those  used  in  triangu- 
lation  or  geodetic  work,  it  may  be  an  advantage  to  arrange  the  base' 
with  three  leveling  screws  instead  of  four.  These  changes  will  always 
be  made  upon  application.  While  the  ordinary  complete  transit  is  more 
compact  and  of  greater  utility  with  four  screws,  in  a  specially  designed 
instrument  for  the  finest  work  it  will  always  be  well  to  consider  the 
advantages  of  the  three-screw  system,  universally  adopted  in  European 
instruments. 

Shifting  Center  for  Facilitating  Plumbing  and  Centering. 

All  our  complete  instruments  are  furnished  with  shifting  plates  for 
the  purpose  of  setting  them  precisely  over  a  point,  after  having  approxi- 
mately done  so  by  the  tripod  legs.  This  arrangement  is  of  the  greatest 
utility  to  the  field  man,  and  we  are  convinced  that  those  who  have 
adopted  it  will  never  again  dispense  with  it. 

While  it  does  not  make  the  instrument  less  rigid  or  portable,  it 
is  so  easily  manipulated,  and  becomes  a  great  labor-saving  factor.  In 
order  to  center  the  instrument  accurately,  two  of  the  leveling  screws 
require  a  slight  loosening,  when  the  transit  may  be  shifted  upon  the 
tripod  until  the  center  of  the  plumb-bob  is  directly  over  the  point  to 
be  occupied.  The  screws  are  then  turned  down  and  the  instrument 
leveled  up  in  the  usual  manner,  when  it  will  stand  as  firm  upon  its 
base  as  required.

2.    The  Centers 

In  manufacturing  this  all-important  feature,  the  very  backbone 
of  the  instalment,  too  much  care  and  attention  cannot  be  bestowed. 

It  is  essential  that  both  of  these  metal  axes  should  have  the  same 
absolute  center  as  the  graduated  plate  and  the  horizontal  telescope  axis, 
whichever  way  the  instrument  may  be  turned.  This  is  accomplished 
by  the  A.  Lietz  Company  by  making  this  detail  a  specialty.  The  care- 
fully chosen  material  for  the  vertical  axes,  the  exact  method  of  turning 
and  fitting  them,  and  the  precision  reached  in  the  manner  of  center- 
ing them,  together  with  the  subsequent  scrutinizing  test  to  deter- 
mine the  slightest  eccentricity,  have  accomplished  results  as  per- 
fect as  mechanical  means  and  human  ingenuity  can  achieve. 

Eccentricity  has  been  a  source  of  annoyance  and  error  to  the 
engineer,  to  determine  which  a  number  of  practical  methods  have  been 
invented  and  put  to  use. 

But  with  our  modern  transit,  if  used  with  ordinary  care,  this 
source  of  error  has  been  eliminated,  or  at  least  reduced  to  the  lowest 
possible  minimum. 

The  length  of  our  centers  is  from  2^4  to  4  inches,  according  to 
size  and  style  of  instrument.  To  our  best  belief,  this  is  more  than  the 
instruments  of  any  of  the  many  different  makes  possess,  having  con- 
stantly handled  a  great  many  of  them  in  repairing.  Yet,  by  examining 
our  illustrations,  it  will  be  noticed  that  with  us  the  limb  and  vernier 
plates  are  nearer  to  the  tripod  head  than  in  those  of  other  make,  owing 
to  the  judicious  placing  of  the  centers,  which  reach  down  into  the 
base,  thus  insuring  the  utmost  stability.  By  comparing  our  cuts  with 
those  in  other  catalogues,  the  reader  will  obtain  a  pretty  fair  idea  of 
what  we  mean  to  impress  upon  him — such  a  comparison  being  better 
than  any  argument  by  either  ourselves  or  others,  based  upon  mere 
assertion. 

Examine  carefully  our  construction  of  the  centers,  and  you  will 
be  soon  convinced  that  our  claim  for  rigidity  and  stability  is  fully 
warranted. 

3.    The  Graduated  Plate 

We  have  now  come  to  the  most  essential  part  —  the  very  soul  of 
the  instrument.  It  is  needless  to  dwell  upon  the  necessity  of  an  accu- 
rate graduation ;  it  is  self-evident,  and  it  becomes  the  instrument- 
maker's  pride  to  make  it  so. 

Page  17 


THE  A.  LIETZ  COMPANY  Sl&ig^lWu^ 

SAN  FRANCISCO,  U.  S.  A. 

We  guarantee  our  work  in  this  particular  as  perfectly  reliable, 
the  graduation  lines  straight,  thoroughly  black  and  of  uniform  width. 

The  plate  is  accurately  centered  and  free  from  eccentricity,  as 
already  explained.    Illustrations  shown  on  Pages  62  and  63. 

The  horizontal  circle  is  graduated  from  o  to  360  degrees,  with 
two  sets  of  figures  running  in  opposite  directions  (unless  ordered 
differently).  They  are  large  and  distinct,  and,  to  avoid  errors  in  read- 
ing, the  figures  of  these  two  sets,  and  those  on  their  corresponding 
verniers,  are  inclined  on  opposing  slants,  thus  indicating  the  direction 
in  which  the  vernier  should  be  read. 

We  recommend  graduations  on  a  solid  silver  ring,  as  that  metal 
offers  many  advantages  for  the  purpose — in  fact,  its  great  permanency 
and  smoothness  renders  it  the  only  satisfactory  surface  for  fine  gradu- 
ations. However,  they  are  made  as  the  customer  desires ;  but  since 
the  additional  outlay  for  silver  graduation  is  only  $10,  we  seldom  have 
any  difficulty  in  impressing  the  purchaser  with  its  advantages. 

It  is  customary  with  us  to  graduate  circles  so  that  they  may  be 
read  to  single  minutes  or  thirty  seconds  of  arc.  We  make  any 
degree  of  refinement  called  for,  but  our  manufactured  goods  are  always 
on  hand  in  the  two  vernier  divisions  named. 

The  I 'crnier 

This  consists  of  a  small  sliding  scale,  movable  upon  a  larger  one, 
so  graduated  that  n  parts  thereof  shall  include  either  n  -\-  1,  or  n  —  I 
parts  of  the  larger  scale.  The  scale  may  be  applied  to  either  straight 
lines  or  arcs,  and  aids  to  determine  the  smaller  divisions  of  measure 
between  the  lines  on  the  larger  scale.   See  illustrations  Pages  62  and  63. 

A  tedious  method  for  measuring  small  values  of  arc  by  means  of 
concentric  circles  was  given  in  the  early  part  of  the  sixteenth  century 
by  a  Portuguese,  Pero  Nunez  (Nonius),  and  after  him  the  name  of 
nonius  is  still  applied  in  European  countries  to  what  we  exclu- 
sively call  a  vernier  here.  This  term  was  justly  given  it  in  honor 
of  the  Dutch  captain,  Peter  Werner,  who  gave  to  the  scale  the  sliding 
shape  in  which  we  now  apply  and  use  it  practically.  Signing  himself 
"Pierre  Vernier"  in  a  discussion  of  the  "Nonius,"  written  by  the 
inventor  in  the  French  language  and  published  in  Brussels  in  1631, 
gave  rise  to  the  term  we  now  almost  universally  employ. 

The  graduations  on  a  vernier  are  usually  so  made  that  n  divisions 
thereof  shall  equal  n  —  1  divisions  on  the  circle. 

It  becomes  a  simple  problem  to  determine  the  value  of  n  from  the 
following  equation :

It  is  customary  to  graduate  the  circles  of  the  Lietz  transits  in 

20-minute  divisions,  reading  to  either  20  or  30  seconds  on  the  vernier. 

20  X  60 
The  value  of  n  in  these  cases  is :  or  60  in  the  former,  and 

20  X  60 


-  or  40  in  the  latter ;  or,  in  other  words,  59  and  39  divisions  on 

the  circle  will  correspond  to  60  and  40  on  the  vernier  respectively. 
Instruments  reading  to  one  minute  of  arc  are  divided  to  30  minutes  on 
the  plate ;  in  that  case  29  circle  spaces  are  equal  to  30  vernier  spaces. 

The  verniers  should  be  covered  with  glass  to  protect  them  from 
exposure,  and  for  ease  in  reading  they  should  be  provided  with  ground 
glass  shades. 

Our  verniers  are  in  such  position  that  the  observer  need  not  step 
aside  in  order  to  read  them,  for  we  place  them  about  30  degrees  from 
the  line  of  collimation.  The  method  of  thus  placing  them  has  been 
pronounced  objectionable,  because  the  size  of  .the  plate  level,  which  is 
at  right  angles  to  the  line  of  collimation,  and  the  more  important  of  the 
two,  has  to  be  reduced.  By  examining  our  instruments,  however, 
any  one  will  see  that  we  have  attained  the  object  without  reducing 
its  length,  without  placing  it  over  the  vernier,  and  without  allowing 
it  to  extend  fnaterially  beyond  the  circumference  of  the  plate  —  all  of 
which  would  be  objectionable  features. 

The  space  between  the  circle  and  the  vernier  must  appear,  through 
a  magnifying  glass,  like  a  fine  black  line.  No  accurate  reading  can 
be  taken  if  the  space  appears  wider  than  a  mere  line  of  uniform 
thickness  under  the  revolution  of  the  plate. 

Clamp  and  Tangent  Screws 

The  lower  clamp  screw  of  our  transit  is  of  the  best  devised  shape 
and  arrangement.  It  is  strong  and  rigid,  and  answers  the  slightest 
touch. 

Page  19 


TUT?     A      T  TTTT'7    /^r^A/T"P  A  KTV    modern  engineers'  and

SAN  FRANCISCO,  U.  S.  A. 

The  upper  clamp  does  not  come  in  contact  with  the  limb,  but  grasps 
the  sleeve  of  the  outside  center.  This  is  far  preferable  to  the  old 
method  of  pressing  together  the  two  plates  by  means  of  a  screw  placed 
at  some  point  on  the  circumference. 

The  tangent  screws  are  single  only,  and  operate  in  metal  cases 
against  opposing  springs.  Great  care  has  been  bestowed  ih  eliminating 
all  lost  motion  of  these  screws.  We;  consider  double  tangent  screws, 
working  against  a  tongue,  as  entirely  obsolete.  Any  instrument  sold 
today  with  double  opposing  tangent  screws  may  be  set  down  as  anti- 
quated and  behind  the  times.  It  is  absolutely  necessary  that  every- 
thing tending  to  create  lost  motion  must  be  carefully  avoided.  While 
adjusting  the  line  of  collimation,  this  source  of  error  becomes  very 
annoying,  for,  in  revolving  the  telescope,  the  plate  is  liable  to  turn 
slightly  and  the  operator  is  never  sure  whether  the  cross-hairs  are  in 
adjustment  or  not. 

The  arrangement  of  our  tangent  screws  combine  simplicity  with 
absolute  reliability.  Being  single,  they  require  but  one  hand  in  manipu- 
lation, and  their  judicious  location  and  spring  case  arrangement  make 
them  active  and  operative  at  any  instant. 

4.    The  Compass 

Our  needle  differs  somewhat  in  shape  from  others,  being  a  little 
smaller  in  the  center  than  towards  the  ends,  for  the  reason  that  the 
magnetic  influence  is  manifested  at  the  ends  only,  so  that  all  the  central 
metal  may  be  called  dead  weight.  Compared  with  those  of  other 
makers,  the  Lietz  needle  is,  therefore,  a  little  lighter,  which  conditions 
the  increased  durability  of  the  point  upon  which  it  poises. 

Hard  steel  has  the  capacity  of  retaining  magnetism  longer  and 
better  than  when  tempered,  and  for  that  reason  we  have  adopted  the 
plan  of  leaving  one-half  inch  on  both  ends  perfectly  hard. 

The  closest  attention  is  given  to  the  center  cap  — ■  which  contains 
an  agate  setting — and  to  the  pin  upon  which  the  needle  rests,  for  the 
accuracy  or  sensitiveness  depends  principally  upon  these  two  details. 
These  needles  possess  that  degree  of  sensitiveness  required  in  a  high- 
grade  instrument.  A  sluggish  needle — one  that  will  hang  like  a  dead 
load — is  not  fit  for  the  observation  of  a  reliable  azimuth. 

The  center  pin  must  occupy  the  true  center  of  the  graduated  circle, 
and  must  stand  normal  to  its  plane.  We  utilize  precise  instruments 
with  high  magnifying  power  to  obtain  the  absolute  true  position  of 
the  pin,  in  order  to  avoid  all  errors  due  to  eccentricity.

The  lifting  arrangement  is  applied  with  the  view  of  raising  and 
lowering  the  needle  gently  and  gradually,  as  any  sudden  drop  to  the 
pin,  or  any  quick  action  of  arresting  its  motion,  is  sure  to  cause  a 
rapid  wearing  of  the  point  and  the  cap. 

The  Compass  is  divided  into  30-minute  divisions,  and  numbered 
from  o  to  90  degrees  in  each  quadrant  from  the  north  and  south  points. 
This  is  done  to  conform  with  the  usual  practice  of  surveyors  in  this 
country  to  record  bearings  in  the  four  quadrants.  But  any  desired 
method  of  numbering  the  compass,  either  from  o  to  180  degrees,  or 
from  o  to  360  degrees,  may  be  had  upon  application. 

In  order  to  record  at  once  the  true  bearings  in  the  field,  instead 
of  the  magnetic,  the  instrument  can  be  provided  with  a  variation  plate, 
1.  e.,  an  arrangement  for  laying  off  the  local  deviation  of  the  needle 
by  a  movement  of  the  graduated  compass  ring,  so  that  the  indicated 
course  of  a  line  shall  show  at  once  its  relation  to  the  true  meridian.  It 
is  so  made  that  the  variation  may  be  laid  off  with  precision  to  the 
minute,  by  the  aid  of  the  instrument's  vernier. 

This  is  done  in  the  following  manner : 

Having  set  the  plate  vernier  to  zero,  adjust  the  instrument  and, 
with  the  aid  of  a  good  reading  glass,  place  it  in  such  a  direction  that 
the  north  end  of  the  needle  shall  point  to  the  zero  of  the  compass  ring, 
which  latter  must  coincide  with  the  little  pointer  provided  for  that 
purpose.  Having  carefully  set  the  instrument  thusly  by  means  of  the 
lower  clamp  and  its  tangent  screw,  which  can  certainly  be  done  to  the 
nearest  minute  of  arc,  we  release  the  clamp  of  the  plate  and  proceed 
to  lay  off  the  amount  of  the  local  deviation  of  the  needle  in  degrees 
and  minutes  by  means  of  the  plate-vernier — to  the  right  if  the  variation 
be  east.  The  instrument  is  now  again  in  a  fixed  position,  the  telescope 
pointing  to  the  true  north,  or  as  much  to  the  left  of  the  needle  as  the 
magnetic  variation  is  east.  We  now  proceed  to  turn  the  ring  until  its 
zero  shall  coincide  exactly  with  the  north  end  of  the  needle,  when  every 
subsequent  reading  of  the  compass,  in  any  position,  will  indicate  the 
bearing  of  the  vertical  telescope  axis  from  the  true  meridian. 

This  simple  little  device  is  fully  up  to  the  standard  of  accuracy 
required,  for  with  care  in  setting  the  needle  we  can  always  obtain 
results  correct  within  the  nearest  minute.  We  find  that  by  this  method 
the  additional  vernier,  usually  placed  inside  of  the  compass  ring,  be- 
comes superfluous,  as  the  plate  and  vernier  of  the  transit  are  perfectly 
capable  of  taking  care  of  the  duties  of  this  unnecessary  accessory.

The  variation  plate  has  proven  a  great  labor-saving  device,  as  the 
observed  courses  require  no  reduction  to  the  true  meridian  subsequently. 
It  is  now  almost  universally  called  for;  and  for  those  practitioners 
with  whom  land  surveying  is  a  specialty  we  should,  by  all  means, 
recommend  it  as  an  indispensable  feature. 

5.   The  Standards  and  Vertical  Arc 

The  standards  are  so  constructed  as  to  give  the  maximum  support 
to  the  telescope,  commensurate  with  the  size  of  the  plate.  They  are 
light,  but  rigid  and  strong. 

To  avoid  unequal  expansion  of  the  metal  in  the  standards  by 
exposure  in  the  hot  sun,  which  has  a  tendency  to  elevate  one  end  of  the 
telescope  axis  and  to  depress  the  other,  vitiating  the  adjustment,  they 
are  now  what  we  call  "Torchon"  finished.  This  finish,  being  a  non-con- 
ductor of  heat,  reduces  to  a  minimum  this  source  of  possible  error, 
which,  in  very  sensitive  instruments,  is  of  sufficient  moment  to  be 
guarded  against.  Other  parts  of  our  instruments  are  also  finished 
in  the  same  manner,  particularly  Level  telescopes,  which  we  shall  have 
reason  to  mention  again  hereafter. 

The  bearings  for  the  telescope  axis  are  made  with  extra  care  and 
attention. 

The  axes  of  the  Lietz  transit  telescopes  are  cut  to  conical  or 
cylindrical  bearings,  which  is  a  feature  altogether  preferable  to  the  cor- 
rugated shape  frequently  found  in  surveying  instruments.  The  advan- 
tage of  the  former  is  very  evident,  in  that  there  is  less  friction  than  by 
any  other  contact;  and,  in  addition  to  that,  it  affords  a  much  finer  fitting 
by  reason  of  its  shape.  But  it  is  very  essential  that  the  hardest  metal 
should  be  used  for  this  purpose,  as  a  material  of  insufficient  hardness 
would  soon  wear,  and  the  axes  would  become  elliptical. 

One  of  the  standards  is  supplied  with  an  adjusting  device  to 
regulate  any  inaccuracy  in  the  motion  of  the  telescope  in  -the  true  verti- 
cal plane,  when  the  centers  of  the  instrument  stand  vertically. 

One  standard  carries  the  arc  for  observing  vertical  angles,  which 
may  be  either  a  full  or  a  half-circle,  as  the  customer  desires.  It  is 
usually  made  to  read  to  minutes,  but  may  be  graduated  finer  if  so 
ordered.  A  clamp  and  tangent  screw  are  provided  on  the  right-hand 
standard,  which  are  made  like  those  already  described  for  the  hori- 
zontal movement.  Every  part  of  the  vertical  measuring  apparatus  is 
strongly  and  accurately  made  and  fitted,  to  insure  the  best  results  in 
its  practical  application.

6.   The  Gradienter 

The  head  of  the  tangent  screw  of  the  vertical  arc  movement  is 
made  somewhat  larger,  properly  silvered  and  graduated  into  a  number 
of  equal  parts  on  its  circumference,  the  thread  of  the  screw  being  cut 
with  great  precision,  so  that  its  revolution  may  be  accurately  recorded 
by  the  divisions  of  the  micrometer  head.     See  illustration  Page  65. 

One  complete  revolution  of  the  screw  corresponds  to  B/io  OI  a  foot 
of  difference  in  level  in  100  feet.  Since  the  head  is  divided  into  fifty 
parts,  it  follows  that  one  division  equals  a  difference  of  yi00  of  a  foot 
in  100  feet.  'We  can  also  furnish  with  a  moveable  head  admitting  a  zero 
netting. 

With  this  attachment  grades  may  be  established  very  quickly.  It 
is  only  necessary  to  set  the  screw  head  to  zero,  level  and  clamp  the 
telescope,  and  turn  the  screw  up  or  down  as  many  spaces  as  there  are 
hundredths  of  a  foot  of  rise  or  fall  in  one  hundred  feet  of  the  grade 
to  be  laid  out.  With  the  small  scale  over  the  screw  thrown  back,  the 
gradienter  is  used  as  an  ordinary  tangent  screw.  It  is  one  of  the  most 
useful  accessories,  is  easily  applied,  and  adds  nothing  to  the  weight  of 
the  instrument. 

This  attachment  is  also  useful  in  the  determination  of  horizontal 
distances,  it  being  obvious  that  the  difference  in  rod  reading  between 
two  complete  revolutions  of  the  screw  will  indicate  at  once  the  distance 
of  the  rod  from  the  observer.  Where  the  ground  is  level,  or  nearly  so, 
the  simple  difference  in  rod  reading  will  suffice;  but  when  this  is  not 
the  case,  the  necessary  corrections  will  have  to  be  applied  to  obtain  the 
true  horizontal  distance. 

7.  The  Spirit  Levels 

We  nave  already  noted  that  for  our  purposes  we  use  the  very 
best  article  obtainable. 

An  instrument  of  precision,  capable  of  measuring  delicate  differ- 
ences, requires  delicate  and  sensitive  levels.  This  is  so  obvious  that  we 
ought  not  to  call  attention  to  it  here,  were  it  not  for  the  fact  that  we 
are  frequently  approached  by  surveyors  who  wish  to  impress  upon 
us  the  idea  that  this  or  that  make  of  instrument  met  with  their  approval 
because  its  bubbles  would  stay  in  place  when  once  adjusted.  For  this 
reason  we  want  to  repeat  that  it  is  no  claim  for  superiority  of  a  spirit 
level  because  it  works  sluggishly.  An  engineer  in  the  field  must  know 
when  his  instrument  is  absolutely  level,  and  its  bubbles  should  indicate 
to  him  at  once  when  this  is  not  the  case.     If  they  do  not  do  so,  then

the  instrument  does  not  come  up  to  the  required  standard  of  a  precise 
tool.  It  would  hardly  do  to  place  a  carpenter's  level  on  a  transit,  yet 
we  have  no  doubt  that  its  excellent  qualities  of  remaining  stationary 
would  find  admirers. 

There  is,  of  course,  a  limit  to  the  degree  of  sensitiveness,  and  that 
we  never  exceed,  adapting  it  in  all  cases  to  the  work  demanded  of  the 
particular  instrument  in  hand. 

Our  levels  are  ground  to  the  proper  curvature,  and  each  is  care- 
fully tested  upon  our  level  tester  before  it  is  attached  anywhere. 

The  telescope  can  be  fitted  with  reversible  level  if  desired. 

8.   The  Telescope 

We  have  now  reached  another  most  essential  feature  of  the  instru- 
ment— that  which  may  be  compared  to  the  head  of  the  body,  containing 
the  delicate  organ  of  sight — the  lens. 

The  Lenses 

We  have  already  called  attention  to  the  fact  that  our  optical  acces- 
sories are  the  finest  made  and  that  we  take  great  pains  to  obtain  the 
best  article  for  the  purpose. 

Without  going  into  the  detail  of  optical  mathematics  and  formulas, 
that  can  be  readily  found  in  any  text-book  on  physics,  we  all  know  that 
it  has  been  the  constant  aim  to  produce  lenses  as  free  from  spherical 
and  chromatic  aberration  as  it  is  possible  to  make  them.  The  lenses 
of  the  Lietz  telescopes  are  an  achievement  in  theoretical  and  practical 
science  of  which  it  would  be  interesting  to  make  some  explanation  had 
we  the  space  to  give  to  it. 

The  Eye-Piece 

Two  forms  of  ■  eye-piece  are  known,  the  one  giving  the  erect 
vision' of  the  object,  the  other  an  inverted  image.  The  latter  admits  of 
a  greater  amount  of  light  and  also  allows  a  longer  focal  length  to  the 
object  glass,  thereby  correcting  spherical  aberration  besides  increasing 
the  magnifying  power. 

We  have  always  considered  this  inverting  form  the  more  advan- 
tageous of  the  two ;  and  we  are  convinced  that  if  our  engineers  would 
accustom  themselves  to  its  use,  it  would  finally  be  preferred ;  but  we 
can  appreciate  the  greater  convenience  of  the  erect  form  when  the  in- 
strument is  used  by  many  men.

The  optical  powers  of  the  telescope  are  in  perfect  keeping  with 
the  accuracy  of  the  centers,  graduation  and  spirit  levels,  insuring  a 
complete  reliability  and  harmony  in  every  part  of  the  instrument  for 
the  most  refined  surveying  work. 

The  eye-piece  (always  erect  unless  specially  ordered)  is  so  arranged 
as  to  permit  its  easy  removal,  if  necessary,  by  simply  unscrewing  it. 
In  replacing,  it  should  always  be  well  tightened  up.  It  is  movable  in 
and  out  by  a  revolving  motion,  turning  the  cap  about  one-sixth  of  a 
revolution  backward  or  forward,  comprising  the  most  practical  and 
efficient  method. 

We  shall  now  describe  in  a  few  words  the  mechanical  construc- 
tion of  its  other  parts. 

Other  Parts  of  Telescope 

The  slide,  to  which  the  object  is  attached,  fits  directly  in  the  out- 
side or  body  of  the  tube.  Particular  attention  is  paid  to  this  part  to 
prevent  even  the  slightest  shake,  and  still  procure  an  equal  and  sure 
motion,  which  is  absolutely  necessary,  as  no  true  adjustment  of  the 
line  of  collimation  is  possible  otherwise.  The  motion  is  given  by  a 
spiral  rack  and  pinion. 

The  sliding  tube  is  protected  from  dust  and  dirt  by  an  exterioi 
metal  cylinder,  called  the  slide  protector. 

A  sun  shade  is  provided  for  the  objective,  which  should  always 
be  attached,  as  the  telescope,  when  focused  to  mean  distance,  is  bal- 
anced with  it;  and  a  cap  is  provided  for  the  protection  of  the  objective 
when  not  in  use. 

The  cross-wire  frame  is  suspended  in  the  tube  by  four  capstan- 
headed-screws,  by  which  it  is  adjusted,  the  frame  being  so  constructed 
that  the  cross-wires  cannot  be  torn,  in  case  the  adjusting  screws  are 
tightened  too  much. 

The  spider  web  used  for  our  instruments  is  properly  treated  to 
avoid  all  twist,  and  to  prevent  its  lengthening  and  becoming  crooked 
in  damp  weather ;  it  cannot  become  loose,  as  it  is  well  secured. 

For  mining  and  tunnel  transits  we  can  provide  proper  means  for 
illuminating  the  cross-wires — an  arrangement  that  is  readily  supplied 
upon  application. 

Quite  a  number  of  glass  diaphragms  have  been  cut  by  us  for. the 
United  States  Coast  and  Geodetic  Survey.  Instead  of  the  spider  webs, 
a  small  disc  of  very  thin  glass  is  fastened  to  the  diaphragm,  on  which 
fine  lines  have  been  drawn  with  a  diamond.     It  is  readily  seen  that 

Page  26

SURVEYORS'  INSTRUMI 


these  cannot  get  out  of  shape,  and  for  stadia  measurements  we  think 
them  of  great  advantage.  The  only  drawback  is  that  small  particles 
of  dust  may  settle  on  the  glass  disc,  and,  as  they  are  in  the  focus  of 
the  eye-piece,  they  will  be  constantly  visible  to  the  observer. 

We  make  no  extra  charge  for  putting  those  diaphragms  into  our 
new  instruments,  if  ordered  in  time. 

Stadia  hairs  are  placed  in  our  transits  (and  levels)  when  ordered. 
We  have  superior  facilities  for  setting  them  with  great  precision  to 
any  desired  ratio  between  distance  and  rod  reading.  It  is  customary 
to  place  them  so  that  they  shall  read  I  foot  on  the  rod  for  a  distance 
of  ioo  feet,  and  to  this  measure  we  always  have  them  in  our  stock 
on  hand. 

The  stadia  hairs  may  be  fixed  or  adjustable.  We  advise  the  fixed, 
as  they  are  less  liable  to  change  their  distance.  In  an  adjustable  set 
the  observer  is  never  certain  that  the  position  of  the  wires  has  remained 
unchanged.  We  have  constructed  a  delicate  optical  and  mechanical 
apparatus  for  fixing  stadia  hairs  accurately  to  any  proportion ;  and 
by  means  of  our  powerful  telescope,  which  has  superior  optical  quali- 
ties, we  can  safely  say  that,  with  proper  care  and  a  little  experience 
in  that  method  of  measuring,  very  satisfactory  results  may  be  obtained. 
The  facilities  for  measuring  across  inaccessible  places,  and  the  speed 
with  which  it  enables  one  to  get  distances,  has  brought  this  method  into 
deserved  prominence  with  our  engineers.  For  topographical  surveys 
it  is  indispensable. 

When  purchasing  a  new  instrument,  it  is  advisable  to  get  one 
that  has  fixed  stadia  wires,  which  increases  the  cost  only  $3,  while  we 
charge  $10  to  put  them  into  a  transit  or  level  sent  to  us  subsequently. 

In  sighting  with  the  telescope  it  is  of  considerable  advantage  to 
have  it  reversible,  and  our  transits  are  made  so  as  to  allow  this  free 
revolution  in  a  vertical  plane.  The  telescope  balances  accurately  when 
in  focus  to  mean  distance,  the  friction  in  the  bearings  being  shaded  to 
such  a  degree  of  nicety  that  it  shall  neither  work  too  hard  nor  too 
loose — a  feature  which  ought  to  have  very  close  attention. 

General  Remarks  About  Telescopes  • 
When  selecting  or  examining  an  instrument,  the  engineer  should 

be  particularly  careful  to  test  the  qualities  of  the  telescope. 

It  should  have  sufficient  magnifying  power  to  correspond  with 

the  finer  qualities  of  the  graduation,  axis,  centers,  spirit  levels,  etc.,  of 

the  instrument.     There  can  be  no  doubt  that  the  excellencies  of  each 

detail  must  compare  with  that  of  any  other.

Now,  by  using  a  low-power  telescope,  the  defects  of  an  inferior 
instrument  may  be  hidden,  or  left  undiscoverable,  and  for  this  reason 
they  will  always  be  found  in  articles  of  lower  grade.  Had  such  an 
instrument  lenses  of  sufficient  magnifying  power,  the  defects  would 
become  apparent  to  the  engineer  at  once.  We  lay  the  greatest  im- 
portance upon  these  facts,  and  for  this  reason  call  particular  attention 
to  them.  Scrutinise  the  optical  abilities  of  the  telescope,  and  you  will 
obtain  the  character  of  the  whole  instrument. 

An  engineer  should  be  careful  to  convince  himself  of  the  real  mag- 
nifying power  before  making  a  purchase.  He  will  find  it  much  to  his 
interest  to  do  so. 

We  have  found  that  the  power  of  first-class  instruments  should 
be  about  twice  as  many  diameters  as  the  length  of  telescope  expressed 
in  inches.  In  inverting  telescopes  it  may  be  materially  increased,  which 
shows  again  that  they  are  of  considerable  importance  in  very  high 
grade  instruments. 

In  another  place  we  have  added  a  practical  method  for  finding  the 
magnifying  power  of  a  telescope,  to  which  we  would  advise  our 
engineers  to  give  some  attention,  and  to  make  use  of  when  about  to 
choose  an  instrument. 

We  have  already  pointed  out  the  importance  of  perfectly  center- 
ing the  lenses,  especially  the  objective.  If  this  is  not  properly  attended 
to,  the  adjustment  can  never  be  perfected  for  long  and  short  distances. 

We  have  heard  many  complaints  of  various  makes  about  the 
change  in  adjustment,  and  after  careful  examination  we  have  found 
that  the  adjustments  remained  intact,  but  that  the  fault  lay  in  the 
objective,  which  had  not  been  correctly  centered.  We  take  great  pains 
to  center  our  object  glasses  perfectly,  and  to  insert  the  lenses  in  such 
a  manner  that  if  taken  out  they  may  be  replaced  in  the  old  position, 
which  is  secured  by  a  notch  and  a  pin.  It  is  not  advisable  for  engineers, 
however,  to  take  these  lenses  from  the  cell,  as  their  cleaning  may  be 
effected  without  removing  them. 

Reverting  again  to  the  magnifying  power  of  telescopes,  it  may 
be  asserted  that  an  increase  thereof  reduces  the  field.  This  is  no  defect, 
if  the  size  of  the  latter  is  retained  large  enough  to  admit  of  stadia  lines 
so  placed  as  to  read  I  :ioo.  We  often  leave  the  field  much  larger, 
however,  in  which  case  there  appears  just  a  slight  dimness  at  the  ex- 
treme border;  this  is  unimportant,  for  it  does  not  retract  any  of  the 
virtues  of  the  glass,  and  possesses,  if  anything,  an  advantage  of  finding 
an  object  more  readily.

The  quality  of  some  of  the  telescopes  of  our  best  makers  has 
often  been  questioned  by  competent  engineers  on  account  of  a  peculiar 
haze  ascribed  to  the  glass.  This  was  found  to  be  caused  by  a  small 
film  of  moisture,  which  settles  between  the  crown  and  the  flint,  and  is 
not  visible  to  the  naked  eye.  We  have  been  convinced,  by  advising 
with  our  optician,  that  the  crown  and  flint  glasses  should  always  be 
connected  with  balsam.  This  does  not  decrease  the  amount  of  light, 
as  formerly  thought,  but,  on  the  contrary,  it  has  advantages  of  clear- 
ness, in  that  it  prevents  foreign  matter  from  settling  between  the  lenses, 
which  always  destroys  the  image ;  the  refrangibility,  too,  is  under  more 
favorable  conditions  in  the  balsam. 

Extra  Accessories  for  the  Transit 

There  are  a  number  of  additions  made  for  transits  used  for  special 
purposes,  and  these  we  keep  on  hand,  and  supply  them  when  called  for. 

For  laying  off  right-angles,  for  instance,  we  can  make  any  pro- 
vision, if  the  customer  will  order  it  in  time.  In  fact,  any  of  the 
accessories,  not  usual  in  the  ordinary  complete  field  instrument,  will 
be  made  as  an  extra  if  our  patrons  will  notify  us. 

For  the  solar  attachment  we  provide  a  block  with  a  thread  on  the 
telescope  axis  to  receive  these  beautiful  little  apparatuses  of  which 
complete  descriptions  will  be  found  later. 

The  Finish. 

This  is  made  to  give  the  instrument  an  elegant,  tasteful  appear- 
ance, without  adopting  a  color  glaring  to  the  eye.  Our  instruments 
are  finished  in  an  elegant  leathered  effect,  but  may  be  bronzed  to  the 
special  taste  of  the  purchaser,  if  he  chooses  to  order  it. 

Size  of  Transit. 

The  dimensions  and  proportions  of  the  several  parts  of  the  transit 
are  given  in  Part  II  of  this  catalogue,  where  the  different  sizes  and 
varieties  of  instruments  made  are  described  more  in  detail. 

Packing. 

This  is  not  at  all  an  unimportant  feature.  Our  transit  is  easily 
taken  from  the  tripod  by  means  of  the  Lietz  friction  coupling  already 
described,  and  set  upon  a  wooden  slide,  to  which  it  is  fastened  by  means 

Page  29

of  two  thumb  screws  and  wooden  clutches — a  manipulation  requiring 
but  a  moment's  time.  Nothing  is  taken  from  the  instrument  except  the 
shade — it  remains  a  complete  whole  from  the  base-plate  to  the  top  of 
the  telescope.  The  board  slides  into  the  box  with  the  transit  in  an 
upright  position,  with  the  clamps  secured  to  keep  it  from  turning.  An 
extra  place  is  provided  for  the  solar  attachment,  if  there  be  one.  The 
door  may  then  be  locked,  and  the  instrument  is  absolutely  safe,  with 
the  least  effort  of  packing  and  adjusting  in  the  box. 

Rubber  cushions  are  provided  at  the  bottom  of  the  case,  to  take 
up  any  sudden  jar  or  jolt  to  which  it  may  be  exposed  during  transpor- 
tation. 

The  Tripod. 

We  have  adopted  the  new  form  of  split  leg — a  construction  which 
combines  the  greatest  stiffness  and  strength  with  the  least  weight.  The 
old  form  of  the  heavy  solid  leg  has  long  since  been  abandoned,  and  we 
no  longer  make  such  a  tripod,  unless  specially  ordered  by  some  con- 
servative customer,  or  for  very  small  instruments.  We  aim  to  reduce 
the  weight  of  everything,  without  sacrificing  steadiness  or  strength  in 
any  particular,  and  that  the  split  leg  meets  these  conditions  better  than 
the  solid  one  must  stand  to  reason. 

The  very  best  white  ash  is  chosen  and  carefully  worked.  Instead 
of  fitting  the  leg  between  two  brass  cheeks,  we  fit  one  cheek  in  the 
leg.  In  the  older  construction  it  frequently  happened,  in  drawing  the 
bolts  closer  to  tighten  a  loose  leg,  that  the  cheeks  would  spring  the 
plate,  or  weaken  the  screws  that  hold  it.  This  is  entirely  obviated  by 
the  new  arrangement  of  these  parts,  for  the  tightening  can  no  longer 
affect  the  plate  in  the  least.  While  in  the  former  the  leg  would  only 
fit  at  the  lower  part  of  the  cheeks  when  drawn  in  by  the  bolt,  it  will 
always  fit  the  whole  surface  of  the  cheek  in  the  plan  we  follow,  and 
after  ten  years'  use  it  will  be  just  as  steady  as  when  new. 

The  shoes  are  made  on  a  gradual  taper  to  a  sharp  point,  and 
securely  fastened  to  the  leg.  They  are  provided  with  a  projection  for 
pressing  upon  with  the  foot  when  setting  up. 

The  large  transit  and  the  level  fit  the  same  tripod — in  fact,  any 
Lietz  instrument  may  be  readily  fitted  upon  the  tripod  we  manufacture, 
for  the  adjustment  of  the  friction  coupling  allows  a  perfect  accommo- 
dation to  any  slight  variation  in  the  parts  of  the  base-plate.

LEVELING   INSTRUMENTS 

I.ietz  levels  are  manufactured  in  two  different  types,  which  we 
aim  tn  keep  constantly  in  stock,  the  Y-level  and  the  Dumpy  level. 

In  the  manner  of  making  these  instruments,  much  that  has  been 
said  of  the  transit  will  hold  good  here,  and  need  not  be  repeated. 

The  three  main  qualities  to  be  secured  in  a  level  are :  stability,  a 
sensitize  bubble  and  a  powerful  telescope. 

To  secure  the  first,  we  need  only  refer  to  the  solid  construction 
of  the  star-shaped  casting  through  which  the  leveling  screws  operate, 
already  described  in  speaking  of  that  feature  in  the  transit.  The  Lietz 
coupling,  too,  plays  an  important  part  here,  for  we  can  make  the  tripod 
connection  absolutely  rigid. 

The  center,  or  spindle,  is  almost  three  and  one-half  inches  long, 
and  is  continued  through  the  damp  up  to  the  bar,  which  enables  us 
to  bring  the  center  of  gravity  as  near  as  possible  to  the  tripod  head. 
Great  care  is  exercised  in  fitting  the  center  to  the  socket,  and,  being 
made  of  the  hardest  composition,  it  must  be  apparent  that  it  is  an 
utter  impossibility  to  wear  out  these  parts,  even  by  fifty  years'  constant 
use.  The  liability  of  bending  the  spindle,  so  common  an  accident  with 
instruments  having  soft  centers,  and  the  fretting  of  the  same,  also 
likely  to  happen  at  times,  is  altogether  avoided. 

The  reasons  for  having  a  sensitive  bubble  have  also  been  carefully 
set  forth  heretofore.  Accurate  work  cannot  be  done  with  a  sluggish 
bubble.  No  matter  how  much  the  virtues  of  the  staying  qualities  may 
be  extolled  by  some  men,  they  are  not  fit  for  refined  work  if  they  do 
not  answer  the  slightest  touch  of  the  leveling  screw.  If  you  can  give 
a  screw  a  twist  or  two  before  the  bubble  loses  its  peaceful  equanimity, 
the  work  in  hand  would  not  be  likely  to  inspire  any  great  confidence. 

Our  level  tube*  is  curved,  so  as  to  give  for  every  two  minutes  of 
arc  a  one-inch  motion  of  the  bubble.  A  refined  level  of  this  character, 
however,  will  only  do  good  service  in  an  instrument  having  perfect 
steadiness  and  a  powerful  and  sharply  defining  telescope.  If  placed 
in  a  level  so  constructed  as  to  be  topheavy,  or  in  one  whose  center  is 
frequently  exposed  by  being  a  part  of  the  tripod  head — and  therefore 
liable  to  collect  dust  both  on  the  cone  and  in  the  socket,  introducing 
sources  of  error  after  every  detachment — then  it  will  indeed  prove 
very  annoying,  should  an  active  bubble  accompany  such  an  instrument.

SAN  FRANCISCO,  U.  S.  A. 


These  structural  defects  are  probably  the  cause  why  many  of  our 
engineers  are  prejudiced  against  sensitive  levels,  and  prefer  a  sluggish 
or  dull  one.  We  can  only  assure  the  reader  again  that  a  lively  bubble, 
even  if  a  little  out  of  center  by  reversing  the  instrument,  will  still 
accomplish  better  results  than  an  inactive  one — one  that  gives  the 
instrument  an  appearance  of  steadiness,  which  in  reality  it  is  far  from 
possessing.  An  engineer  only  deceives  himself  if  he  trusts  to  a  slowly 
acting  level,  which  gives  apparent  satisfaction  by  concealing  the  errors 
that  a  sensitive  one  would  soon  indicate.  A  precision  instrument 
never  suffers  by  having  its  qualities  exposed  by  a  high-grade  bubble. 

The  level  telescope  should  have  power  and  definition.  It  is  hardly 
necessary  to  make  that  statement,  after  all  that  has  been  said  on  this 
subject  in  a  previous  chapter.  It  has  been  our  earnest  endeavor  to 
obtain  these  results,  without  increasing  the  dimensions  of  the  telescope 
and  the  other  parts  of  the  instrument,  beyond  the  proper  limits  for 
steadiness  and  portability.  A  length  of  eighteen  inches  we  have  found 
to  give  the  most  advantageous  results.  Experience  has  shown  us,  that 
although  an  increased  length  adds  to  the  magnifying  power,  it  would 
only  be  of  value  if  the  other  parts  of  the  instrument  were  enlarged 
in  proportion,  which,  on  the  other  hand,  would  make  it  too  heavy  for 
convenience  in  carrying  and  offer  more  surface  to  the  wind,  thereby 
reducing  steadiness,  we  believe  that  with  our  1 8-inch  level  even  the 
most  extensive  requirements  in  engineering  are  fully  met. 

Our  new  and  improved  eye-piece,  and  the  use  of  an  objective  of 
proper  proportioned  diameter,  enable  us  to  obtain  a  magnifying 
power  of  33.  An  increase  of  diameter  adds  very  little  to  the  weight 
of  the  telescope,  and  does  not  require  a  longer  bar  and  larger  plates, 
as  an  increase  in  length  necessarily  would,  to  retain  steadiness.  An 
aperture  of  l^i  inches,  used  to  its  full  value,  affords  a  high  illumina- 
tion with  the  above-mentioned  power,  as  the  tube  is  large  enough  to 
let  all  the  rays  proceeding  from  the  object  glass  pass  through  to  the 
field  of  view. 

The  diameter  of  the  aperture  of  the  object  glass  divided  by  the 
power,  gives  the  diameter  of  the  pencil  of  light  entering  the  eye.  In 
our  telescope  we  obtain,  therefore,  iy%  -f-  33  =  y,4  of  an  inch,  which 
shows  that  power  and  brightness  are  in,  accordance  with  optical  law. 
To  force  the  power  beyond  these  limits  we  cannot  conscientiously  do, 
as  that  would  be  allowable  only  under  certain  circumstances — such  as 
a  perfectly  clear  atmosphere  with  a  strong  illumination  of  the  object.

The  collars,  upon  which  the  telescope  rests  in  the  Ys,  are  made  of 
the  hardest  bell  metal,  and  admit  of  a  position  in  cither  direction,  that 
is.  the  telescope  is  reversible.  The  very  first  requisite  is  that  these 
collars  must  be  of  exactly  equal  diameter  and  perfect  cylinders.  If  this 
be  not  the  case,  the  line  of  collimation  will  not  be  parallel  to  a  tangent 
of  the  bubble's  curve  at  its  highest  point,  when  the  latter  indicates  a 
horizontal  position,  and,  for  this  reason,  a  true  level  cannot  be  obtained 
with  such  an  instrument. 

It  is  very  often  believed  that  in  the  course  of  adjusting  the 
V-lcvcl.  by  reversal  of  telescope  and  revolving  on  center,  the  bubble 
will  indicate  any  inequality  of  the  collars,  but  this  is  by  no  means  true. 
If  the  Ys  are  both  filed  out  to  the  same  angle  (this  is  generally  the 
case,  or  at  least  very  nearly  so.  as  most  makers  file  them  out  by  means 
of  gauges),  the  inequality  of  the  collars  may  be  quite  appreciable,  and 
yet  the  instrument  will  be  adjustable  in  all  its  parts ;  in  other  words, 
it  may  be  so  adjusted  that  the  bubble  on  all  reversals  in  the  Ys  and 
revolutions  on  center,  will  always  give  the  same  reading  at  both  ends, 
that  is,  indicate  a  true  horizontal  position.  A  final  test  is  necessary, 
therefore,  after  the  instrument  is  properly  adjusted,  to  ascertain  the 
equality  of  the  collars.  This  will  be  mentioned  further  on  under  the 
head  of  adjustments. 

Similar  causes  for  error  are  introduced  if  a  particle  of  sand  lodges 
between  the  collar  and  Y,  which  illustrates  the  necessity  of  keeping 
these  parts  free  from  all  dust  and  dirt. 

It  is  readily  demonstrated  to  what  considerable  difference  any 
slight  inequality  in  the  diameters  of  the  collars  may  give  rise  to,  but 
the  space  here  will  not  permit  of  a  mathematical  discussion  of  the 
subject. 

We  have  carefully  explained  this  defect,  owing  to  the  conviction 
on  our  part  that  it  is  a  much  more  common  one  than  is  generally  sus- 
pected. Numerous  cases  have  come  under  our  observation,  where  this 
fault  existed  in  a  remarkable  degree.  And  in  the  perusal  of  many 
works  on  engineering  and  surveying,  we  have  noticed  very  few  that 
call  attention  to  this  material  defect,  and  still  less  that  give  a  correct 
test  for  it. 

We  are  aware  that  accurate  leveling  may  be  done  with  a  level  out 
of  adjustment,  if  the  utmost  precaution  is  taken  to  have  equi-distant 
fore-  and  backsight.  But  looking  at  it  from  this  point  of  view,  why 
not  use  the  dumpy  level  then,  instead  of  the  more  costly  Y-level? 

The  Finish  is  made  to  give  the  instrument  an  elegant  appearance,

and  yet  obtain  all  the  qualities  alluded  to  in  a  previous  discussion  of  the 
same  subject.  The  telescope  is  "Torchon"  finished  to  avoid  that 
unequal  expansion  of  the  metal  heretofore  mentioned.  This  finish  is 
of  a  color  pleasing  to  the  eye,  is  applied  so  that  it  remains  intact  for 
a  long  time,  and  if  somewhat  worn  after  a  long  period  of  exposure,  it 
can  be  readily  reapplied  without  difficulty  at  a  trifling  expenditure. 
This  finish  is  a  modern  feature,  and  one  that  is  so  universally  pre- 
ferred, that  we  have  no  hesitation  in  recommending  it  to  our  patrons 
as  worthy  of  their  consideration.  However,  we  also  keep  in  stock  the 
bronzed  and  lacquer  finished  level  telescopes,  so  that  the  customer  may 
have  his  choice  in  the  matter. 

The  level  telescope  is  supplied  with  a  slide  protector  and  with  a 
sunshade ;  the  latter  should  always  be  put  on  to  balance  it  evenly.  A 
cap  is  also  provided  for  the  objective  and  a  shutter  for  the  eye-lens. 

In  all  other  matters  the  transit  details  obtain  here  also. 

Fixed  stadia  wires  can  be  supplied,  set  to  read  1 :100,  for  which  an 
extra  charge  is  made  if  ordered,  unless  included  in  price  stated. 

The  center  movement  is  checked  and  regulated  by  a  clamp  and 
tangent  screw,  exactly  similar  to  those  of  the  transit. 

Other  useful  accessories  are  attached,  but  any  feature  not  usually 
found  in  the  Y-level,  must  be  ordered  beforehand. 

We  are  likewise  in  a  position  to  make,  but  upon  order  only,  levels 
of  precision  for  the  most  exact  work  that  the  geodetic  surveyor  is 
called  upon  to  perform.  These  are  provided  with  all  the  delicate 
details  that  such  an  instrument  must  possess.  We  invite  correspond- 
ence upon  the  subject  of  geodetic  instruments,  and  will  cheerfully 
furnish  prices  after  consulting  with  our  patron  upon  the  nature  and 
character  of  the  instrument  required. 

The  packing  in  the  case  has  been  made  so  as  to  assure  safety  in 
transportation,  with  the  least  trouble  and  inconvenience  to  the  operator. 
The  level  is  taken  from  the  tripod  by  a  third  of  a  revolution  of  the 
base  plate,  which  undoes  the  Lietz  Coupling.  It  is  let  down  to  stand 
upright  in  the  box,  when  the  closing  of  the  lid  holds  everything  firmly 
in  place.  In  all  minor  details  the  level  box  is  similar  to  the  transit 
case,  every  means  being  employed  to  insure  absolute  safety. 

The  Dumpy  Level. 

In  this  instrument  the  aim  has  been  to  construct  it  in  such  a 
manner  that  it  shall  be  as  compact  as  possible  by  dispensing  with 

Page  34 


§K$y  THE  A.  LIETZ  COMPANY 

S  \n   i  u  INCISCO,  U.  S.  A. 

certain  features  of  the  Y-level,  not  absolutely  necessary  in  order  to  do 
good  and  reliable  work. 

The  principles  governing  its  construction  are  the  same  as  those 
that  obtain  in  the  more  elaborate  Y-instrument. 

The  telescope  is  permanently  held  by  two  vertical  arms  attached 
to  the  level  bar,  and  cannot  be  taken  therefrom.  The  level  tube  rests 
upon  these  anus,  over  the  telescope,  and  is  also  fixed.  The  telescope 
tube  is  thereby  brought  as  close  as  possible  to  the  tripod  head,  which 
is  a  desirable  characteristic.  All  the  other  features  remain  the  same 
as  in  the  Y-level  construction. 

This  instrument,  which  is  almost  exclusively  used  in  Europe,  has 
not  yet  met  with  that  favor  by  American  engineers,  which  its  simplicity 
and  accuracy  so  justly  deserves.  This  is  due  partly  to  its  greater 
inconvenience  in  adjusting  as  compared  with  the  Y-level,  and  partly 
on  account  of  defective  construction,  inferior  telescope  and  other 
neglected  details,  which  usually  obtain  in  instruments  of  this  kind. 

We  are  confident  that  a  dumpy  level  possessing  a  good  telescope, 
sensitive  bubble  and  stability,  will  do  just  as  good  work  as  the  more 
costly  Y-level.  While  the  adjustment  of  the  latter  is  made  more 
readily,  the  former  will  retain  it  longer. 

( )ur  dumpy  level  has  a  bronze  center,  a  16-inch  telescope,  and  a 
vial  of  such  curvature,  as  to  give  for  each  inch  of  motion  of  the  bubble 
an  angle  of  three  minutes. 

There  is  no  clamp  or  tangent  screw  to  this  form  unless  ordered 
by  the  customer. 

The  bar,  telescope  and  vial  case  are  "Torchon"  finished,  and  the 
latter  may  be  provided  with  a  folding  mirror,  which  acts  as  an  important 
protection  to  the  more  exposed  spirit  level  when  shut  down,  or  as 
an  indicator  to  the  observer  at  the  eye-piece,  of  the  exact  position  of 
the  bubble,  when  elevated.     See  No.  20M,  Page  101. 

The  stadia  hairs  may  also  be  supplied  to  the  dumpy  level. 

Other  Levels  on  Sale. 

In  addition  to  the  high  grade  instruments  described,  we  also  keep 
on  hand  a  supply  of  smaller  and  less  costly  goods  for  leveling.  With 
these  instruments  work  may  be  done  by  the  ditcher,  irrigator,  con- 
tractor, grader,  farmer,  dike-builder,  gardener,  plumber,  architect, 
forester  and  military  man,  sufficiently  precise  for  many  ordinary  pur- 
poses, wherein  great  accuracy  is  not  required.

REMARKS 

In  the  foregoing  we  have  endeavored  to  give  the  reader  a  fair 
idea  of  the  principal  engineering  instruments  made  by  this  firm.  We 
desire  to  convince  our  future  customers — our  old  patrons  we  have  long 
since  convinced — that  we  are  building  conscientiously  upon  scientific 
principles,  that  every  part  and  detail  has  been  carefully  studied  to 
meet  the  requirements  of  our  engineering  fraternity,  of  the  climate, 
and  of  all  those  conditions  that  influence  the  shape  and  character  of 
every  feature  of  the  surveying  instrument.  It  must  permit  of  all 
operations  at  the  least  expenditure  o"f  time,  it  must  be  compact,  it 
must  be  light,  it  must  be  absolutely  accurate,  it  must  be  rigid,  it  must 
be  stable  and  it  must  possess  strength.  And  wherever  a  possible  im- 
provement is  suggested  in  any  detail,  it  must  be  applied  at  once  and 
tested  as  to  its  probable  merits,  and  if  it  prove  of  value,  no  time  must 
be  lost  in  introducing  it.  These  are  the  principles  that  have  governed 
the  manufacture  of  the  articles  which  we  have  brought  to  your  notice. 

New  improvements  have  always  had  our  attention,  without  any 
regard  of  the  expenses  incurred  in  experimenting.  We  need  only 
refer  to  the  introduction  of  aluminum  in  the  manufacture  of  survey- 
ing instruments,  which,  we  are  fully  convinced,  has  been  crowned  with 
success,  to  prove  to  our  patrons  that  we  never  allow  any  conservative 
notion  to  rule  the  establishment.  The  particulars  of  this  new  field  of 
manufacture  will  be  found  in  another  chapter  of  this  part  of  the 
Manual. 

With  the  object  constantly  in  view  to  make  only  the  very  best 
article  that  can  be  produced,  and  ever  ready  to  introduce  improve- 
ments and  to  experiment  with  suggestions  that  may  lead  to 
them,  our  instruments  are  held  at  a  price  that  is  commensurate  with 
their  qualities.  Their  values  are  rated  by  those  current  among  first- 
class  instrument  makers ;  they  are  no  more,  but  they  are  no  less.  We 
do  not  handle  cheap  goods,  and  the  trade  that  we  are  most  anxious 
to  please  is  that  willing  to  pay  a  fair  price  for  a  number-one  article. 

It  was  our  purpose  to  describe  in  this  catalogue  only  the  instru- 
ments for  which  there  exists  the  greatest  demand,  and  for  this  reason 
we  do  not  intend,  at  this  time,  to  enter  into  any  detail  of  the  manu- 
facture of  other  scientific  apparatus  that  we  are  in  position  to  furnish 
upon  due  notice. 

Theodolites  of  the  highest  grade  for  the  most  exact  purpose,

upon  order  to  any  desired  shape  and  design,  and  with  every  required 
accessor)'. 

We  also  manufacture  the  topographer's  plane-table,  either  in  its 
simplest  form,  as  recently  perfected  by  the  highest  authorities,  or  in 
its  most  delicate  arrangement  of  parts,  as  devised  for  work  of  the 
greatest  precision  capable  of  being  put  on  paper.  A  number  of  plane- 
tables  made  for  our  institutions  of  learning,  and  for  surveying  depart- 
ments of  the  I'.  S.  Government,  have  given  absolute  satisfaction. 

The  modern  improved  plane-table  alidade  is  a  particular  specialty, 
to  which  we  have  given  considerable  time  and  attention.  This  instru- 
ment has  been  constructed  by  us  of  aluminum,  which  has  been  a  per- 
fect success,  proven  by  the  fact  that  many  have  been  almost  daily 
in  use  for  many  years,  under  very  trying  conditions,  without  giving 
rise  to  the  first  complaint.  Under  the  head  of  Aluminum  for  Sur- 
veying Instruments,  this  will  be  again  referred  to.  By  a  combination 
of  aluminum  and  aluminum  bronze,  the  center  of  gravity  of  the 
alidade  may  be  brought  close  to  the  foot  of  the  standard,  which  is  a 
very  essential  point  in  its  construction. 

ALUMINUM    FOR    SURVEYING    INSTRUMENTS 

A  great  deal  has  been  said  and  written  about  this  comparatively 
new  metal  of  late,  so  that  its  characteristics  have  become  generally 
known. 

Its  color  is  a  dull  white,  similar  to  silver,  and  rather  pleasing  to  the 
eye.  It  embodies  many  qualities  that  make  it  a  very  valuable  material 
in  the  mechanic  arts.  It  is  quite  soft,  but  possesses  malleability, 
tenacity  and  ductility,  so  that  it  may  be  made  into  very  thin  sheets, 
or  drawn  out  into  fine  wire.  It  is  a  conductor  of  heat  and  electricity. 
One  of  its  principal  features  is  that  it  does  not  oxydize  in  the  atmos- 
phere, and  that  it  does  not  lose  its  brightness  under  conditions  that 
would  tarnish  silver  and  blacken  it,  for  sulphuretted  hydrogen  or  sul- 
phide of  ammonium  do  not  influence  its  color.  But  the  greatest  ad- 
vantage is  its  remarkable  light  weight,  the  specific  gravity  being  only 
2.6,  or  one-fourth  of  that  of  silver,  and  for  this  particular  quality  its 
use  has  been  sought  in  the  manufacture  of  articles  requiring  small 
weight,  ever  since  the  cost  of  its  production  has  justified  it. 

One  of  the  many  alloys  is  the  so-called  aluminum  bronze,  which 
unites  hardness  with  malleability,  and  is  therefore  extensively  used 
for  many  purposes.  This  alloy,  however,  gains  little  in  lightness 
as  compared  with  the  ordinary  metals.

SAN  FRANCISCO,  U.  S.  A. 

Since  it  has  been  the  constant  aim  to  produce  field  instruments 
that  shall  combine  strength  with  the  least  practical  weight,  there  could 
not  have  been  found  a  better  application  for  aluminum  than  in  the 
instrument-maker's  art. 

It  was  necessary  to  experiment  with  it  in  different  directions, 
particularly  as  to  the  proper  alloy — it  being  much  too  soft  in  its  pure 
state — that  shall  give  the  required  tensile  strength  and  stiffness,  make 
it  workable  without  fretting,  and  yet  add  little  to  its  weight.  An  alloy 
is  now  made  that  fully  satisfies  these  conditions. 

One  of  the  principal  objections  urged  against  it  in  the  manufacture 
of  surveying  instruments  is,  that  on  account  of  extreme  lightness  they 
would  not  be  steady  enough  in  the  wind.  This  firm  has  built  over 
iooo  transits  and  levels  of  aluminum,  and,  in  our  opinion,  they  are 
quite  as  rigid  as  any  other,  if  properly  constructed,  care  being  taken 
to  adhere  to  the  old  material  in  such  details  where  it  cannot  be  dis- 
pensed with.  We  have  found  that  the  stability  of  an  instrument 
depends  more  particularly  upon  the  construction  of  its  lower  parts. 
If  the  combination  of  base-plate  and  leveling  apparatus  be  made  so 
that  the  instrument  can  be  rigidly  held,  the  center  of  gravity  may  be 
brought  down  lower,  and  that  in  itself  would  tend  to  increase  its 
stability. 

Aluminum  transits  are  made  by  the  A.  Lietz  Company  in  three 
sizes,  being  complete  field  instruments  with  every  accessory.  The 
large  transit  weighs  10  pounds,  and  the  smaller  one  A]A  pounds,  which 
reduces  the  weight  by  40%.  The  construction  is  precisely  the  same  as 
in  the  instruments  already  described. 

The  base-plate  is  of  composition  metal,  the  inner  center  of  the 
hardest  bell  metal,  and  the  outer  center  of  bronze.  The  leveling  screws 
are  also  of  composition,  as  well  as  the  telescope  axis. 

These  transits  may  either  be  left  in  the  beautiful  natural  color  of 
the  metal,  or  other  shades  may  be  applied.  The  standards  are 
"Torchon"  finished. 

The  Licts  Telescopic  Solar  Attachment  is  now  made  of  aluminum, 
which  can  only  be  an  improvement  in  any  direction,  whether  its  weight 
be  added  to  the  top  of  a  transit  made  of  the  red  metal,  or  to  one  of 
the  new  metal.  Lightness  in  the  solar  attachment  is  a  very  desirable 
feature,  and  that  may  be  easily  obtained  now. 

In  the  Y-level  the  base-plate  and  leveling  screws  and  center  are 
of  composition  metal ;  the  collars,  the  hardest  bell  metal ;  and  the  rest, 
aluminum.     It  has  an  18-inch  telescope,  its  weight  being  6l/2  pounds.

We  also  manufacture  a  plane-table  alidade  of  aluminum,  with  a 
ruler  of  aluminum  bronze.  This  instrument,  although  of  the  same 
weight  as  one  of  the  ordinary  metal  of  the  same  size,  possesses  the 
particular  advantage  of  having  its  center  of  gravity  as  low  as  it  can 
possibly  be  brought  to  the  table,  and  that  when  placed  upon  the  board 
it  will  be  absolutely  stable,  and  will  not  be  influenced  by  the  wind, 
which  causes  the  ordinary  alidade  to  tremble  and  travel  on  the  paper. 

And  this  is  the  reason  why  we  should  object  very  strongly  to  an 
aluminum  rule  in  a  plane-table  alidade.  This  part  of  the  alidade 
should  be  of  heavy  material,  as  well  as  the  lower  part  of  the  standard, 
while  the  rest  may  be  constructed  as  lightly  as  possible.  In  this  case 
little  or  nothing  may  be  gained  in  the  weight,  but  very  much  is  gained 
in  stability,  when  compared  with  an  instrument  made  of  one  metal 
throughout.  Under  no  condition  should  the  rule,  which  is  the  base 
of  the  structure,  be  made  of  a  light  material. 

Twenty-six  years  of  experience  in  the  construction  of  aluminum 
surveying  instruments  finds  us  ready  to  advocate  the  judicious  use  of 
this  material.  We  have  applied  it  in  transits  and  levels,  and  have 
accomplished  a  saving  in  weight  of  about  40  per  cent.  Great  care  is 
exercised  in  the  proper  distribution  of  the  metal.  We  have  already 
stated  that  in  a  transit  aluminum  is  never  used  in  the  construction  of 
the  base-plate,  centers,  leveling  screws,  telescope  axes  and  all  minor 
parts  having  threads.  The  principal  horizontal  members,  the  plates, 
are  of  aluminum,  strongly  ribbed. 

Much  has  been  written  about  its  high  coefficient  of  expansion, 
and  particular  stress  has  been  laid  upon  the  effect  of  unequal  expansion 
necessarily  induced  by  the  use  of  different  metals.  If  this  matter  be 
considered  for  one  moment,  however,  it  will  soon  be  seen  that  practi- 
cally there  can  be  no  serious  result  from  this  source.  In  the  first 
place,  the  difference  between  the  coefficients  of  brass  and  aluminum 
is  altogether  too  small*  that  the  effect  of  any  possible  distortion  in 
material  judiciously  placed  need  necessarily  be  feared.  Glass  plays 
a  very  important  part  in  the  make-up  of  a  transit.  The  coefficient  of 
expansion  in  glass  is  very  low  (0.8  mm.  per  meter,  raised  100°  C) 
and  a  metal  best  adapted  for  our  purpose  would  be  one  having  the 
same  coefficient.  Now,  as  far  as  brass  and  aluminum  are  concerned, 
it  is  readily  seen  that  there  is  practically  no  difference  in  them  when 
compared  with  glass.  As  long  as  glass  is  used,  one  may  as  well 
employ  aluminum  as  brass  for  the  constructive  parts,  for  while  the 

*  Physical  laboratories  have  established  the  following:  For  brass  1.88  mm.  per  meter  of 
length,  raised  in  temperature  100°  C;  for  aluminum  2.34.  Our  deductions  are  made  from  these 
data.

expansion  of  the  latter  exceeds  that  of  glass  0.000072  inches  per  linear 
foot  for  i°  Fahrenheit,  that  of  the  former  does  so  only  by  0.000103. 
Unequal  expansion,  therefore,  is  not  a  source  of  error  that  need 
reasonably  be  feared. 

The  more  vital  objection  to  a  light  instrument — its  greater  un- 
steadiness in  the  wind  when  compared  with  a  heavier  make — is  some- 
thing we  have  already  referred  to.  We  have  made  and  sold  over  1000 
aluminum  transits  and  levels,  and  every  one  has  been  a  proof  of  our 
statement  made  twenty  years  ago :  that  the  stability  depends  more 
upon  the  construction  of  its  base  and  connection  with  the  tripod  than 
it  does  upon  the  weight  of  what  may  be  called  its  superstructure — 
the  part  above  the  leveling  head. 

It  may  also  be  mentioned  incidentally  that  a  fall  will  injure  an 
aluminum  instrument  less  than  if  made  of  red  metal.  Not  only  is  this 
theoretically  correct,  but  our  actual  experience  in  this  line  has  proven 
to  us  the  fact  that  from  ordinary  accidents  the  lighter  instruments 
are  always  less  seriously  injured  than  the  heavier  ones. 

The  testimonials  from  our  customers  will  show  the  public  that  the 
aluminum  instruments  made  by  our  firm  have  given  the  fullest  satis- 
faction, and  have  not  disappointed  our  expectations. 

We  are  firmly  convinced  of  the  adaptability  of  aluminum  for  sur- 
veying instruments,  and  for  that  reason  our  firm  has  gone  extensively 
into  that  branch  of  manufacture,  for  which  every  facility  has  been 
added'  recently  to  the  capacities  of  the  shop.  The  aluminum  instru- 
ment is  forty  per  cent,  lighter  than  the  other,  is  just  as  strong,  is  just 
as  precise  in  its  workings,  possesses  every  requisite  detail  of  a  com- 
plete field  instrument,  and,  we  claim,  is  just  as  stable.  Those  of  the 
engineering  fraternity  who  have  to  carry  the  transit  all  day,  the  mining 
and  railway  men,  who  climb  the  mountain  sides  during  the  long  sum- 
mer days  from  early  until  dark,  will  not  be  long  in  finding  out  these 
advantages  and  in  putting  them  to  a  severe  test  in  every  direction. 
After  manufacturing  aluminum  instruments  for  twenty-six  years  we 
have  had  no  occasion  to  regret  it,  and  find  constant  encouragement 
from  the  best  professional  men. 

CARE    OF    INSTRUMENTS 

The  greatest  source  of  danger  to  a  delicate  instrument  is  careless 
handling.  It  is  often  subjected  to  violent  usages  for  which  there  is 
absolutely  no  need.  The  rude  way  of  manipulating  its  delicate  parts; 
the  unnecessary  display  of  digital  strength  in  operating  a  clamp;  the 
useless  strain  applied  to  the  leveling  screws;  the  careless  manner  of 

Page  40

SAN  FRANCISCO,  U.  S.  A. 

carrying  it;  the  rough  method  of  taking;  it  out  of  its  case,  or  replacing 
it :  and  the  incautious  closing  of  a  lid  or  door  of  a  box  by  force,  before 
the  instrument  is  somewhat  adjusted  to  its  position ;  all  these  are 
sources  of  danger  that  vitiate  its  adjustments  and  cause  no  end  of 
trouble  and  expense.  Although  a  well-made  instrument  is  so  designed 
as  to  stand  many  a  shock  without  direct  injury,  any  daily  repeated 
abuse  is  sure  to  have  its  ill  effect,  from  which  your  work  must  suffer. 

As  the  usefulness  of  a  transit  or  level  may  be  preserved  for  many 
years  by  a  little  attention  to  details,  we  shall  enumerate  a  few  of  the 
principal  points  which  the  engineer  will  do  well  to  observe. 

Always  protect  your  instrument  from  rain  by  throwing  over  it 
a  waterproof  bag;  and  if  it  gets  wet  at  all,  clean  it  thoroughly  after 
getting  under  shelter.  It  is  not  well  to  enter  a  hot  room  from  the 
cold  air,  without  giving  it  some  protection.  The  condensing  vapor 
settling  on  the  metal  and  glasses  is  certain  to  give  rise  to  injuries. 
It  is  always  safe  to  place  the  instrument  in  its  case  before  going  into 
a  warm  room  in  winter.  It  is  not  well  to  leave  your  transit  or  level 
exposed  for  hours  to  the  hot  sun.  Shade  must  be  given  either  by  a 
hood  thrown  over  the  instrument,  or  by  an  umbrella. 

But  accidents  are  liable  to  happen,  and  for  that  reason  we  have 
noted  down  a  few  remedies  in  case  of  an  emergency. 

The  general  tendency  in  the  use  of  the  screws  is  to  overstrain 
them.  This  should  never  be  done,  especially  with  the  cross-wire 
screws,  which,  when  brought  up  too  tight,  are  liable  to  constant  change 
and  loss  of  adjustment.  The  leveling  and  clamp  screws,  if  over- 
strained, wear  out  sooner  and  may  show  fretting.  If  this  takes  place, 
they  should  be  taken  out  and  brushed  with  a  little  coal  oil  or  benzine. 
The  nuts  are  best  cleaned  by  screwing  a  flat  piece  of  soft  wood  through 
their  apertures.    In  putting  them  together  oil  them  slightly. 

Fretting  of  the  centers  and  of  the  telescope-slide  will  interfere 
more  with  a  correct  working  of  the  instrument  than  any  other  part  out 
of  order.  They  should  be  watched,  therefore,  very  closely,  and  as  soon 
as  any  rough  motion  manifests  itself,  it  should  be  remedied  at  once, 
if  possible,  by  an  instrument  maker.  If  this  cannot  be  had,  and  the 
fretting  is  in  the  slide,  first  scrape  and  then  burnish  down  the  place 
where  it  frets.  It  may  also  be  ground  slightly  with  oil  and  very  fine 
pumice  stone  dust,  which  is  best  obtained  by  rubbing  two  pieces  on 
each  other.  After  grinding  then  a  little,  the  tubes  should  be  cleaned 
and  placed  together  again  with  oil  only;  then  move  them  in  and  out 
a  number  of  times,  wipe  the  oil  off,  and  finally  put  them  together

when  dry.  Should  the  fretting  occur  in  the  centers  (if  properly  made 
and  constructed,  so  that  they  do  not  come  apart  in  detaching  the 
instrument  from  the  tripod,  this  will  never  happen),  employ  the  same 
means;  and  if  this  be  not  effective,  place  a  washer,  made  of  paper  or 
a  thin  card,  between  the  shoulders.  This  will  cause  a  shake,  making 
accuracy  impossible,  and  will  introduce  errors  of  parallax  in  reading 
off,  which  is  better,  however,  than  to  destroy  the  centers  wholly.  The 
best  unguent  for  them  is  very  fine  watch  oil.  Regarding  our  centers, 
we  are  fully  prepared  to  assure  our  customers  that  no  fretting  will 
ever  happen,  as  they  are  never  exposed,  and  made  with  the  utmost 
care. 

The  object-slide  should  not  be  oiled.  Never,  under  any  condition, 
use  emery  in  trying  to  repair  an  instrument,  as  it  cannot  be  removed 
again  and  will  grind  continually. 

An  efficient  lubricant  for  leveling  screws,  clamps,  pinions,  etc.,  is 
well-rendered  marrow. 

If  an  instrument  is  upset,  thereby  bending  centers  and  plates, 
do  not  turn  it  unnecessarily,  as  this  will  disfigure  the  graduation,  but 
send  it  to  a  competent  instrument  maker  immediately.  There  should 
be  no  delay  in  repairing  defects. 

In  the  matter  of  the  tripod,  it  is  wise  to  look  to  the  screws  that 
hold  the  legs  frequently,  and  to  keep  them  well  tightened  up ;  and  to 
inspect  the  shoes,  to  see  that  they  do  not  come  loose.  An  instrument 
cannot  be  steady  if  there  is  any  shake  in  the  tripod,  which  is  its  sup- 
port and  must  be  firm  in  every  particular. 

The  graduation  is  a  very  delicate  detail  to  handle,  and  should  be 
approached  only  with  the  utmost  care.  It  is  safe  to  leave  this  part- 
to  the  instrument  maker,  and  not  to  attempt  to  remove  the  plates,  as 
they  cannot  be  properly  recentered  without  the  aid  of  a  testing 
apparatus.  An  exposed  graduation  may  be  cleaned  with  a  little  watch 
oil  and  a  chamois  skin,  taking  care  not  to  touch  the  edges  while  this 
is  done. 

To  preserve  the  sensitiveness  of  the  needle,  the  center  pin  must 
be  prevented  from  becoming  dull.  The  instrument  should  never  be 
lifted  without  raising  and  arresting  the  needle,  and  if,  upon  letting 
it  down  again,  the  swing  is  too  large,  gently  stop  it  when  within  a 
few  degrees  of  its  natural  bearing.  Every  check  and  start  must  be 
made  gently,  never  abruptly.  Should  the  point  become  dull,  it  is  best 
to  send  it  to  an  instrument  maker ;  if  this  be  not  practicable,  a  watch- 
maker may  perhaps  attend  to  it.    It  should  be  remembered,  however, 

Page  42 


SURVEYORS'  lXSTKIM  I  IE    A.  LIETZ   COMPANY 

SAN   FRANCISCO,  U.  S.  A. 

that  the  point  of  poise  must  be  centered — that  is,  occupy  the  center  of 
the  graduated  circle.  This  cannot  be  done  by  a  watchmaker,  and  is 
only  to  be  relied  upon  if  made  in  an  instrument  maker's  shop. 

If  a  needle  is  made  of  good  steel,  well  hardened  and  properly 
charged,  it  will  not  often  lose  its  magnetism;  and  if,  when  placed 
away,  it  is  always  brought  to  line  in  the  meridian,  it  will  retain,  or 
even  increase  is  polarity.  If  a  needle  has  lost  its  magnetism  it  may 
be  charged  again  with  an  ordinary  horseshoe  magnet ;  one  of  three 
inches  in  length  will  be  suitable  for  this  purpose.  The  operation  is 
this :  hold  the  magnet  with  the  poles  upward,  then,  with  a  gentle  pres- 
sure, pass  each  pole  of  the  needle  from  center  to  extremity  over  the 
opposite  pole  of  the  magnet,  describing  before  each  pass  a  circle  with 
a  diameter  of  about  double  the  length  of  the  needle,  taking  care  not 
to  return  it  in  a  path  near  the  pole.  If  the  magnet  is  strong  enough, 
the  needle  need  not  be  taken  out  at  all,  but  by  raising  it  against  the 
glass  and  then  passing  the  magnet  over  this,  it  will  be  charged  suffi- 
ciently. After  charging,  the  needle  has  lost  its  balance,  which  may 
be  easily  restored  by  shifting  the  balance  wire  on  the  south  end. 

The  observer  should  always  satisfy  himself  that  there  be  nothing 
about  his  clothing,  especially  in  the  make  of  the  buttons,  that  would 
have  any  influence  upon  the  needle. 

In  the  matter  of  the  telescope,  intelligent  handling  will  do  much 
towards  preserving  its  accuracy  and  reliability  for  a  long  time.  In 
cleaning  any  of  the  lenses,  use  a  soft  rag  or  chamois  leather.  If  the 
glasses  should  become  greasy,  or  very  dirty,  wash  them  with  alcohol. 
The  inner  faces  will  seldom  require  cleaning,  and  it  is  not  advisable 
to  take  the  telescope  apart  too  often,  as  it  is  likely  to  destroy 
its  adjustment.  If  dust  should  settle  on  the  cross-hairs,  it  is  safest 
not  to  touch  them.  The  only  remedy  that  may  be  tried  is  to  take  out 
both  the  object-glass  and  the  eye-piece,  and  to  blow  gently  through  the 
tube.  This  may  remove  the  dust  without  injuring  the  threads,  but  it  is 
quite  a  delicate  operation. 

Cross-hairs  may  be  replaced  in  the  field  by  the  engineer.  The 
spider  web  is  cleansed  from  dirt  by  placing  it  in  water  for  a  few 
minutes.  A  little  manipulation  readily  removes  any  particle  that  may 
adhere  to  the  thread.  After  drying  for  a  moment,  adjust  it  to  the 
diaphragm,  previously  cleaned  from  dust,  and  attach  it  by  means  of 
a  little  shellac.  It  requires  considerable  practice  to  do  this  nicely, 
for  a  spider's  web,  although  quite  strong,  cannot  be  handled  by  clumsy 
fingers  without  parting;  but  in  the  case  of  an  emergency  the  engineer 
must  try  to  do  the  best  under  all  circumstances.

AND 
INSTRUMENTS 


SAN  FRANCISCO,  U.  S.  A. 

Referring  again  to  the  lenses,  it  is  well  to  remember  that  in  taking 
them  apart,  the  centering  is  disturbed,  and  the  engineer  is  not  able  to 
replace  them  properly,  especially  if  they  fit  loosely  in  the  cell,  which 
is  very  often  the  case.  The  staining  of  flint-glass  lenses  is  caused  by 
the  corrosion  of  the  oxide  of  lead  contained  in  the  glass.  This  will 
generally  occur  when  the  lens  is  kept  in  a  damp  place  for  some  time. 
In  cleaning  an  object-glass,  care  should  be  taken  not  to  rub  it  any 
more  than  necessary.  Brush  off  the  dust  first  with  a  camel-hair  brush, 
and  then  wipe  it  carefully  with  a  clean  piece  of  chamois  leather.  If 
very  dirty,  wash  it  with  alcohol  or  water  and  soft  chalk,  being  careful 
to  have  the  latter  free  from  grit. 

Considering  that,  in  cleaning,  each  rub  will  destroy  more  or  less 
of  the  fine  finish  of  the  lens,  upon  which  depends  the  brightness  and 
brilliancy  of  the  image,  the  surveyor  will  be  well  repaid  for  his  care 
in  this  particular. 

Similar  attention  must  be  bestowed  upon  the  eye-piece.  With  our 
high  power  eye-pieces,  a  motion  of  only  three-sixteenths  of  an  inch  is 
necessary  to  allow  for  difference  in  eyes.  As  the  sliding  motion  is  for 
this  purpose  alone,  it  is  not  at  all  necessary  to  disturb  it  after  it  has 
once  been  properly  adjusted,  as  long  as  the  same  person  is  using  the 
instrument;  even  in  packing  it  away  in  the  case  the  eye-piece  may  be 
left  so,  as  this  extra  extension  is  allowed  for  in  the  box.  The  cap  is 
provided  with  a  slide  to  protect  the  eye-lens  from  dust  while  the 
instrument  is  not  in  use ;  the  engineer  should  never  neglect  to  close 
this,  and  to  cover  the  object-glass  with  its  cap  as  well,  as  soon  as 
the  instrument  is  set  at  rest. 

Repairs.* 

We  are  fully  prepared  to  make  careful  repairs  to  all  instruments, 
from  the  graduation  of  an  arc  or  circle,  and  the  straightening  of  a 
center  or  plate,  to  the  setting  of  a  simple  screw.  In  this  particular 
branch  we  have  operated  here  for  the  last  thirty-odd  years,  and  have 
gained  the  fullest  confidence  of  our  people.  We  need  only  state  here 
that  we  guarantee  satisfaction  to  our  customers  in  every  way. 

As  we  are  located  in  California,  separated  by  the  breadth  of  the 
continent  from  our  Eastern  colleagues,  we  are  necessarily  required  to 
repair  instruments  of  almost  every  known  make,  and  this  has  com- 
pelled us  to  procure  the  various  requisites  in  the  workshop  for  all 

*  Experience  has  taught  us  that  it  is  not  wise  to  allow  an  ordinary  mechanic  to  attempt 
instrumental  repairs,  as  frequently  resorted  to  in  inland  towns.  It  is  always  the  case  that 
this  proves  ruinous  to  the  instrument,  and  subsequent  repairs  will  be  more  extensive  and 
expensive  than  if  it  had  been  shipped  to  the  instrument-maker  at  once.  Express  charges 
are  of  far  less  importance,  and  may  be  made  very  reasonable.  See  notice  in  front  of 
this  manual.

emergencies.  Today  we  are  in  the  position  to  renew  any  part  of  an 
instrument,  no  matter  where  it  was  originally  manufactured.  Time  and 
money  will  be  saved  by  sending  directly  to  us,  and  we  shall  try  to  give 
our  customers  every  satisfaction.  Whatever  is  entrusted  to  us  will 
be  thoroughly  overhauled  and  put  in  the  best  possible  condition,  unless 
specified  orders  are  received  to  confine  the  repairs  to  certain  details. 
As  a  general  thing  it  ought  to  be  left  to  our  judgment  as  to  what  the 
instrument  requires ;  it  may  cost  a  little  more  if  you  follow  our  advice 
in  this  particular,  but  it  will  certainly  be  more  satisfactory  in  the  end. 
It  will  save  time,  trouble  and  additional  expense.  In  the  course  of  our 
examination  of  an  instrument  needing  repairs,  we  discover  defects  that 
could  not  be  apparent  to  any  one  before  its  parts  were  separated  and 
individually  tested.  What  may  appear  of  no  consequence,  and  is  there- 
fore neglected,  is  quite  likely  to  lead  to  all  sorts  of  subsequent  inaccu- 
racies in  your  work.  Years  of  experience  in  this  particular  line  have 
taught  us  the  advisability  of  urging  this  point  upon  our  patrons. 

Considerable  correspondence  is  had  from  inquiries  about  the  cost 
of  repairs.  Although  it  is  impossible  to  state  the  exact  figures  before 
an  examination,  there  are  certain  rates  for  ordinary  repairing  that  we 
may  mention  here. 

The  most  expensive  instrument  in  this  regard  is  the  transit,  being 
the  most  complicated  in  parts.  If  injured  by  a  fall,  new  centers  and 
a  new  telescope  axis  is  generally  required,  the  cost  varying  from  $10 
to  $50,  reaching,  sometimes,  much  higher.  If  slightly  injured  it  will 
vary  from  $5  to  $15. 

Injuries  sustained  by  leveling  instruments  are  generally  less 
serious.  A  new  level  vial  costs  from  $2  to  $7.50,  according  to  size 
and  sensitiveness.  Instruments  defective  in  construction  or  workman- 
ship will  not  require  a  sensitive  level,  as  that  would  be  a  source  of 
constant  annoyance  to  the  engineer ;  the  bubble  should  be  chosen  to 
harmonize  with  the  general  qualities.  As  a  rule,  we  attach  to  the 
better  class  of  instrument  a  level  that  shall  give  for  each  inch  of  motion 
of  the  bubble  an  angle  of  two  minutes ;  to  the  inferior  grade,  one  of 
three  or  four  minutes. 

Compasses  sent  to  us  are  generally  injured  by  the  dulling  of  the 
center  pin.  Sometimes  the  plates  and  sights  are  bent  and  the  glass 
broken.  Often  the  center  cap  is  worn  out,  and  a  new  one  is  required. 
The  cost  of  repairing  ranges  from  $2  to  $8,  and  even  as  high  as  $10.

is  far  superior  to  the  flat  style,  costs  $5.  A  new  center  pin,  75  cents.

Careful  readjustments  made  under  the  collimators  are  charged 
for  at  the  rate  of  $2.50  for  each  instrument. 

Transits  and  levels  should  always  be  accompanied  by  the  leveling 
plates ;  the  tripod  and  head  need  not  be  sent.  With  compasses  the 
ball  spindle  should  be  sent. 

We  advise  our  customers  to  pack  their  instruments  carefully,  when 
sending  them  to  us  for  repairs,  as  they  are  liable  to  material  injury 
if  this  precaution  be  neglected.  The  space  in  the  box  between  the 
different  parts — of  the  transit  particularly — may  be  filled  with  soft 
paper  wads  to  protect  it  from  jars  and  blows.  It  is  well  to  put  the 
case  in  an  additional  box,  a  little  larger  in  dimensions,  in  such  a  man- 
ner that  the  top  of  the  case  is  plainly  visible  and  its  leather  strap  handy 
for  carrying.  The  space  between  the  case  and  the  box  may  be  padded 
with  shavings,  or  some  •30ft  material  to  take  up  the  shocks.  Mark  upon 
the  top  of  the  box  in  large  legible  letters :

The  name  of  the  sender  and  his  address,  together  with  the  value  of  the 
instrument,  should  also  appear  on  the  box. 

This  will  insure  comparative  safety  in  transportation,  which  is  a 
point  that  should  be  well  observed  by  the  engineer.  And  this  precau- 
tion would  also  increase  the  responsibiliy  of  the  carrier,  in  case  the 
instrument  had  suffered  during  transportation. 

When  an  instrument  is  sent  to  us  for  repairs,  a  letter  or  postal 
card  should  be  mailed  at  the  same  time,  to  inform  us  of  the  fact, 
giving  the  necessary  directions,  and  stating  when  the  return  is  required. 
The  receipt  of  the  instrument  will  be  acknowledged  by  us  at  once.

SURVEYORS'  INSTRUMENTS 


ADJUSTMENTS 

Adjusting  an  instrument  consists  in  delicately  moving  to  the  right 
or  left,  and  up  or  down,  certain  parts  that  must  be  either  parallel  or 
at  right-angles  to  each  other.  This  is  done  by  slightly  turning  a  num- 
ber of  capstan-headed  screws  or  nuts  by  means  of  a  small  steel  rod, 
called  an  adjusting  pin.  Adjusting  the  vernier  and  compass  consists 
in  placing  certain  points  in  a  straight  line ;  but  as  these  corrections  are 
always  made  by  the  instrument  maker,  they  do  not  properly  apply  to 
the  subject  before  us.  Verniers,  limb  and  needle,  if  properly  placed 
at  the  outstart,  will  not  need  any  correction  in  the  ordinary  use. 

Of  the  Transit. 

i.  Adjustment  for  Parallax. — This  is  a  very  essential  one, 
and  must  be  looked  to  carefully  in  every  surveying  instrument,  whether 
transit,  level  or  theodolite.  It  consists  in  so  focusing  the  eye-piece 
that  the  cross-hairs  shall  stand  out  distinctly  and  well-defined,  when 
the  telescope  is  directed  upon  an  object  in  focus.  If  this  is  not  properly 
done  the  hairs  will  be  dim;  they  will  appear  to  travel  and  to  seem 
unsteady  when  set  on  a  mark.  We  know  that  this  has  given  consid- 
erable vexation  to  the  observer,  and  instruments  have  been  disparag- 
ingly condemned  for  their  apparent  parallax,  when  nothing  more  was 
necessary  than  a  slight  movement  of  the  eye-tube  to  focus  the  hairs 
properly.  This  fact  should  be  well  borne  in  mind.  Our  eye-pieces  are 
quite  easily  moved  in  or  out  by  a  revolving  motion,  which  affords  a 
very  fine  and  precise  adjustment  to  focus. 

Operation. — Direct  the  telescope  so  as  to  have  a  clear  view  of  the 
sky,  and  then  turn  the  eye-tube  by  the  cap  as  just  described,  until  the 
cross-hairs  stand  out  like  two  sharp  and  distinctly  drawn  black  lines. 
After  a  few  trials  this  is  accomplished  without  difficulty.  Then  try 
the  telescope  upon  some  object  brought  into  focus  and  test  the  clear- 
ness of  the  wires.  A  point  now  bisected  must  stay  so  while  the  eye 
is  moved  laterally  in  front  of  the  eye-hole.  If  it  remains  stationary, 
there  is  no  parallax  and  the  adjustment  is  made.  Once  properly  set, 
the  eye-piece  may  remain  for  the  same  observer  for  all  time,  and  need 
not  be  adjusted  from  day  to  day.  Attention  has  already  been  called 
to  this  point  in  a  previous  chapter,  where  it  was  noted  that  the  instru- 
ment box  was  made  large  enough  to  allow  the  eye-piece  to  extend 
beyond  the  tube.  (The  sun-shade  should  be  put  on  the  telescope  first, 
and  then  focused  to  mean  distance  to  balance  it  properly.) 

2.     Plate  Levels. — The  object  is  to  set  the  levels  at  right-angles 

Page  47 


TTJT?  A  T  TFT7  PAA^D  4  MV  MODERN  ENGINEERS'  AND 
Ifllj     -TV.     J-/JU-J  1  Li     Kj\j£t\.r  j\.XS\       SURVEYORS1  INSTRUMENTS 

SAN  FRANCISCO,  U.  S.  A. 

to  the  vertical  axis  of  the  instrument,  so  that  when  the  bubbles  are 
centered  the  axis  is  truly  vertical. 

Operation. — Bring  the  bubbles  to  the  middle  of  the  tube  by  means 
of  the  leveling  screws,  then  turn  the  instrument  on  its  center  180 
degrees.  If  they  remain  central  for  any  position,  they  are  in  adjust- 
ment ;  if  not,  they  must  be  elevated  or  depressed  at  one  end  to  correct 
them.  One-half  of  the  required  correction  is  made  with  the  capstan- 
headed  screws  on  the  vial  case,  the  rest  by  the  leveling  screws  of  the 
instrument.  Several  repetitions  of  the  operation  may  be  required  be- 
fore attaining  accuracy.  It  is  well  to  have  the  plate  in  such  a  position, 
that  the  levels  shall  be  parallel  to  a  pair  of  opposing  foot  screws.  If 
they  are  out  considerably,  it  is  better  to  adjust  one  first,  approxi- 
mately, and  then  the  other. 

3.  The  Standard  Bearings. — The  telescope  should  revolve  in 
a  vertical  plane  when  the  instrument  is  level.  One  end  of  the  tele- 
scope axis  must  be  either  raised  or  lowered  until  accuracy  is  reached. 
A  capstan-headed  screw  is  attached  for  that  purpose. 

Operation. — Set  the  instrument  up  within  about  fifty  feet  of  the 
wall  of  a  house.  Take  a  well-defined  point  as  high  up  as  possible  on 
the  wall ;  clamp  and  bisect ;  then  turn  down  the  telescope  and  put  a  point 
in  line  as  low  on  the  wall  as  may  be  conveniently  reached.  Reverse 
the  telescope  and  direct  again  to  the  upper  mark,  if  you  please ;  clamp 
and  bisect ;  turn  down  to  the  lower  mark,  and  if  it  is  bisected,  the 
telescope  revolves  in  a  vertical  plane  and  requires  no  adjustment.  If 
it  does  not  strike  the  point  absolutely,  one-half  of  the  difference  is 
taken  up  by  the  capstan-headed  screw,  and  the  adjustment  is  done. 
Several  repetitions  of  the  operation  may  be  required.  It  is  not  neces- 
sary to  level  the  instrument,  but  it  should  be  brought  in  such  a  position 
as  to  admit  the  bisecting  of  two  well-defined  points.  Care  should  be 
taken,  however,  that  the  observation  is  made  at  the  intersection  of  the 
cross-wires,  and  that  the  instrument  is  securely  clamped. 

This  adjustment  should  always  be  made  before  that  of  the  cross- 
wires,  for  this  reason :  that  unless  points  of  equal  height  are  taken 
in  the  subsequent  adjustment  of  the  vertical  hair,  it  will  only  then  prove 
correct,  if  the  telescope  revolves  in  a  truly  vertical  plane.  It  is,  there- 
fore, always  better  to  look  to  this  before  the  cross-hairs  are  adjusted. 

This  adjustment  may  also  be  made  by  means  of  an  accurate  strid- 
ing level,  such  as  manufactured  by  this  Company  for  use  in  high-grade 
instruments.  The  transit  must  be  precisely  leveled  up  by  the  foot- 
screws  and  plate  bubbles,  after  which  the  striding  level  is  placed  across 

Page  48

SAN  FRANCISCO,  U.  S.  A. 

the  telescope,  resting  upon  its  axis.  It  is  evident  that  the  bubble  will 
indicate  any  deficiency  in  the  horizontal  parallelism  of  this  axis,  and, 
therefore,  any  error  in  the  true  vertical  motion  of  the  telescope,  which 
may  be  corrected  until  the  bubble  of  the  striding  level  remains  centered. 

4.  The  Cross-wires. — The  line  of  collimation  should  be  at  right- 
angles  to  the  axis  upon  which  the  telescope  revolves. 

Assuming  that  all  the  required  conditions  have  been  fulfilled  by 
the  instrument  maker — having  placed  the  telescope  in  the  center  of  the 
instrument,  and  having  the  tubes  perfectly  straight  and  normal  to  the 
telescope  axis,  which  are  necessary  instrumental  requirements,  there 
are  two  methods  that  may  be  employed.  One  is  by  means  of  back  and 
fore-sights,  which  is  that  generally  used ;  the  other  consists  of  a  test 
by  means  of  three  points  in  a  range,  where  the  middle  one  is  occupied. 
Preceding  either  method  the  hair  should  be  made  truly  vertical,  so 
that  either  the  upper  or  lower  end  will  bisect  a  point  when  the  tele- 
scope is  moved  up  and  down.  This  is  easily  done  by  loosening  the 
diaphragm  and  turning  it  slightly  in  the  required  direction.  To  accom- 
plish this  the  instrument  must  be  leveled  up. 

Operation,  First  Method. — Occupying  a  point,  direct  the  telescope 
to  some  well-defined  mark,  about  four  hundred  or  five  hundred  feet 
distant ;  clamp  and  bisect  it ;  then  revolve  the  telescope  and  place  a 
point  in  the  opposite  direction  at  about  the  same  distance.  Now  un- 
clamp  and  turn  the  instrument  half-way  around ;  set  the  hair  again  on 
the  first  point,  revolve  the  telescope  and  sight  to  the  second  point. 
If  the  intersection  bisects  the  latter,  the  vertical  hair  is  in  adjustment. 
If  not,  the  error  can  be  corrected  by  the  capstan-headed  screws,  which 
afford  a  lateral  motion  of  the  diaphragm.  With  them  the  vertical 
thread  should  be  moved  one-fourth  of  the  space  intercepted  between 
the  direction  of  the  telescope  and  the  direction  of  the  second  point. 
Several  repetitions  may  be  necessary  to  obtain  accuracy. 

The  reason  why  only  one-fourth  of  the  space  should  be  corrected 
for,  becomes  evident  from  the  fact  that  in  the  first  revolution  of  the 
telescope  the  error  of  the  hair  is  doubled ;  and  after  reversing  the 
instrument  and  revolving  the  second  time,  it  is  again  doubled,  but  on 
the  opposite  side,  so  that  the  true  direction  lies  exactly  half  way  be- 
tween the  two,  and  to  correct  for  it  we  must  move  the  hair  one-half 
the  space  between  the  true  line  and  one  of  the  points. 

It  is  not  necessary  to  level  the  instrument  in  order  to  make  this 
adjustment ;  but  in  case  it  is  not  leveled  up,  the  observations  must  be 
made  exactly  at  the  intersection  of  the  cross-wires.

It  must  be  remembered  that  the  image  at  the  cross-hairs  is  in- 
verted, and  that  in  consequence  the  screws  must  be  moved  in  appar- 
ently wrong  directions. 

If  there  is  any  lost  motion  in  the  tangent  screw,  great  care  should 
be  exercised  in  handling  the  telescope,  so  as  not  to  influence  its  align- 
ment. 

Operation,  Second  Method. — Locate  with  the  telescope  three 
points  in  one  direction,  which  are  necessarily  in  a  straight  line,  as  long 
as  the  vertical  movement  of  the  telescope  is  in  adjustment.  Occupy 
the  middle  point  with  precision,  and  bisect  one  of  the  end  points ; 
revolve  the  telescope  and  sight  at  the  other  end  point.  If  this  is  bi- 
sected, the  instrument  is  in  adjustment ;  if  not,  correct  for  it  by  taking 
up  one-half  the  error.  This  method  requires  leveling  of  the  instru- 
ment. 

Thus  far  we  have  been  speaking  of  the  vertical  hair  only,  as  it  is 
the  more  important  in  a  transit  telescope.  In  a  plain  transit — that  is, 
one  without  a  telescope  level  and  without  a  vertical  arc — the  horizontal 
thread  simply  serves  to  define  the  middle  of  the  vertical  one,  so  that 
the  observation  may  always  be  confined  to  a  particular  point  in  the 
latter.  But  if  a  level  is  attached  to  the  telescope,  then  the  horizontal 
hair  should  be  brought  into  the  optical  axis,  before  the  level  is  set 
parallel  to  the  line  of  collimation;  otherwise,  though  adjusted  for  long 
distances,  it  will  fail  to  be  correct  for  short  sights. 

Operation. — Set  up  the  instrument  near  a  house  or  fence  and  level 
up  carefully.  Clamp  the  telescope,  and  by  means  of  its  tangent  screw 
bisect  a  point  several  hundred  feet  distant;  then  turn  on  center  and 
mark  a  point  on  the  house  or  fence,  about  ten  feet  distant.  Now  un- 
clamp  telescope,  reverse  it,  revolve  on  center,  and  again  bisect  the  near- 
est point.  Turn  instrument  on  center  and  see  whether  the  hair  inter- 
sects the  further  point.  If  it  does  not,  the  correction  must  be  made, 
by  lifting  or  lowering  the  diaphragm  by  means  of  the  upper  and 
lower  capstan-headed  screws,  until  the  bisections,  after  repeated  trials, 
will  coincide. 

5.  The  Telescope  Level. — The  object  of  this  adjustment  is  to 
make  the  level  parallel  with  the  line  of  collimation.  The  principle 
underlying  the  method  is :  that  points  taken  with  the  same  angle  of 
elevation  or  depression,  and  equally  distant  from  the  instrument,  are 
of  equal  height. 

Operation. — Set  up  on  a  nearly  flat  surface  and  level  carefully. 
On  opposite  sides,  at  equal  distances,  drive  two  stakes  giving  the  same 

Page  SO 


^^£^1^;^  THE  A.  LIETZ  COMPANY 

SAN  FRANCISCO,  U.  S.  A. 

level-rod  reading,  with  the  telescope  bubble  centered  in  each  instance. 
These  points  are  necessarily  on  a  level  with  each  other.  Now  move  the 
instrument  to  a  point  in  line  with  both,  and  about  ten  feet  distant  from 
one.  Level  up  again.  Take  a  rod  reading  on  the  nearer  and  then  on 
the  further  stake.  If  they  agree,  the  level  is  in  adjustment;  if  not, 
move  the  telescope  with  its  tangent  screw  over  nearly  the  whole  error, 
and  sight  again  at  the  nearer  stake  and  then  at  the  further,  repeating 
this  until  the  readings  are  the  same  on  both,  when  the  telescope  is  truly 
horizontal.  Now  bring  the  bubble  in  the  center  of  the  tube  by  the 
correcting  screws  of  the  level,  and  the  adjustment  is  completed. 

This  adjustment  may  also  be  made  in  a  room  with  the  aid  of  a 
surveyor's  level,  with  absolute  accuracy. 

Operation. — A  few  feet  (one  or  more)  from  each  other  set  up 
the  transit  and  level,  each  directed  to  the  other.  The  cross-hairs  of 
the  level  must  be  illuminated  by  a  light,  so  that  they  shall  become 
plainly  and  clearly  visible  through  the  transit.  For  this  purpose  cover 
the  eye-end  of  the  level  with  a  bit  of  white  paper  and  place  a  lamp 
behind  it.  Focusing  both  instruments  properly  will  make  the  hairs 
appear  very  distinctly.  Now,  if  both  instruments  are  properly  colli- 
mated,  the  level  carefully  leveled  up,  and  the  transit  telescope  of  such 
height  that  we  may  view  the  interior  of  the  level's  tube,  we  are  ready 
to  adjust  the  transit  telescope  to  a  level  plane,  which  is  done  by  simply 
placing  the  intersection  of  its  cross-hairs  delicately  over  the  intersec- 
tion of  the  level's  cross-hairs.  All  that  is  required  after  that,  is  to 
center  the  transit's  level  bubble  by  means  of  the  proper  adjusting 
screws. 

This  method  recommends  itself  on  account  of  its  extreme  sim- 
plicity. 

6.  Zero  of  Vertical  Arc. — This  adjustment,  once  made  by  the 
instrument  maker,  is  seldom  vitiated.  The  object  is  to  have  the  zero 
line  of  the  circle  agree  with  the  zero  mark  of  its  vernier,  when  the 
level  of  the  telescope  indicates  a  horizontal  position,  and  when  the 
centers  of  the  instrument  are  truly  vertical. 

Operation. — The  instrument  must  be  carefully  leveled  by  the 
small  plate  bubbles,  and  then  the  telescope  by  means  of  its  level.  This 
accurately  accomplished,  the  vernier  is  shifted  until  the  zero  lines 
coincide.  This  must  be  carefully  done,  so  that  the  instrument  is  not 
disturbed,  and,  when  the  vernier  is  fastened,  care  must  be  taken  to 
allow  a  space  that  shall  neither  be  too  small  nor  too  great  between  it 
and  the  vertical  circle.     In  the  first  case  it  would  bind  under  certain 

Page  51

conditions  of  temperature,  and  in  the  latter  the  observer  would  not  be 
able  to  obtain  an  accurate  reading.  The  coincidence  of  the  zero-lines 
must  be  made  with  a  magnifying  glass,  and  all  parallax  avoided. 

7.  Centering  the  Field  of  View. — On  some  transit  telescopes 
there  will  be  found  another  set  of  four  capstan-headed  screws,  exactly 
alike  to  that  which  regulates  the  cross-hair  diaphragm,  and  placed  in 
a  position  quite  close  to  it.  These  screws  are  for  the  purpose  of  direct- 
ing the  tube  of  the  eye-piece  in  such  a  manner  that  the  field  of  view 
may  be  divided  by  the  cross-wires  into  four  uniform  quadrants;  that 
is,  they  enable  the  operator  to  so  adjust  his  field  that  it  may  be  bisected 
horizontally  and  vertically  by  the  threads.  In  the  Lietz  transits  this 
adjustment  has  been  omitted,  for  the  reason  that  the  tubes  are  made 
of  such  length  and  with  such  care — being  absolutely  straight — that 
there  is  no  need  of  displacing  the  field,  after  the  line  of  collimation 
has  been  made  to  agree  with  the  optical  center,  and  the  hairs  are 
properly  adjusted.  The  lines  can  never  appear  noticeably  out  of  the 
field  in  our  transits,  and  any  additional  movement  in  the  parts  of  the 
telescope  would  neither  be  useful  nor  desirable.  A  first-class  transit 
instrument  can  dispense  with  this  arrangement  altogether,  and  for 
this  reason  it  is  not  usually  found  there.  With  an  extra  long  telescope, 
however,  there  would  be  a  slight  advantage  in  being  able  to  direct  the 
field  of  view,  for  a  possible  fall  of  the  instrument  may  so  injure  the 
tube  that  it  could  not  be  made  absolutely  straight  again  afterwards, 
and  in  consideration  of  this,  we  have  adopted  this  correction  only  in 
the  case  of  the  18-inch  Y-level,  which  is  the  most  liable  to  be  damaged 
in  that  way.  It  alone  possesses  two  sets  of  capstan-headed  screws  near 
the  eye-end  of  the  telescope — one  for  the  adjustment  of  the  cross-hairs, 
and  the  other  for  shifting  the  field  of  view  so  that  it  shall  appear  equally 
divided  by  them. 

Of  the  Y-Level. 

There  are  three  principal  adjustments.  The  spirit  level  must  be 
parallel  to  the  axis  of  collimation ;  it  must  be  at  right-angles  to  the 
vertical  axis  of  the  instrument;  the  axis  of  collimation  must  agree 
with  the  optical  axis. 

There  are  other  instrumental  requirements  which  belong  to  the 
instrument  maker,  however,  and  it  is  with  the  above  three  adjustments 
only  that  the  surveyor  has  to  deal,  as  they  are  likely  to  become  dis- 
turbed in  time. 

Before  examining  the  adjustments,  the  sun-shade  should  be  placed 
on  the  telescope,  as  it  is  only  accurately  in  balance  with  this.

1ST  Adjustment. — To  set  the  spirit  level  parallel  to  the  line  of 
collimation,  and,  at  the  same  time,  place  its  axis  in  a  plane  with  that 
of  the  telescope.    It  is  best  to  attend  to  the  latter  first. 

Operation. — Turn  the  telescope  so  as  to  stand  over  two  opposing 
foot-screws,  clamp  the  instrument  and  bring  the  bubble  to  the  center 
of  the  tube ;  then  rotate  the  telescope  in  its  Ys,  so  as  to  put  the  level 
considerably  out  of  a  vertical — say  about  15  or  20  degrees.  If  the 
bubble  changes  its  position,  it  shows  that  the  axis  is  not  in  a  plane 
with  that  of  the  telescope.  Correct  it  by  moving  the  two  side  screws 
of  the  level  case,  until  one-half  of  the  deviation  has  been  taken  up. 
A  few  repetitions  will  insure  accuracy,  and  destroy  the  side  motion 
of  the  level. 

The  level  must  now  be  made  parallel  with  the  line  of  the  bottom 
of  the  collars. 

Operation. — Bring  the  bubble  to  the  center  of  the  tube;  then 
reverse  the  telescope  in  the  Ys  end  for  end ;  do  this  carefully.  The 
displacement  of  the  bubble,  if  there  be  any,  is  the  double  error,  which 
is  corrected  by  taking  up  one-half  of  it  by  means  of  the  adjusting  nuts 
on  the  level  case,  and  the  other  half  with  the  leveling  screws  of  the 
instrument.  This  operation  is  repeated  until  the  bubble  remains  in  the 
center. 

To  accomplish  a  proper  adjustment  of  the  level  to  the  line  of  colli- 
mation, it  becomes  absolutely  necessary  that  the  collars  be  of  equal 
diameter.  We  have  already  referred  to  the  importance  of  even  collar 
dimensions,  and  have  laid  great  weight  upon  this  requisite;  and  here 
again  we  shall  point  out  the  errors  to  which  a  neglect  therein  may  lead. 
A  Y-level  in  such  an  event  is  not  any  better  than  a  dumpy,  and  will 
have  to  be  adjusted  as  such. 

Providing  the  Ys  are  filed  out  to  the  same  absolute  angle,  the 
instrument  may  still  be  adjustable  in  all  its  parts : — the  spirit  level  may 
be  made  parallel  to  the  line  of  the  bottom  of  the  collars ;  the  Ys  may 
be  so  adjusted  that  the  bubble  will  remain  in  the  center  of  the  tube; 
the  line  of  collimation  may  be  brought  to  the  center  of  revolution  of 
the  telescope ;  and  this  reversed  end  for  end  in  the  Ys,  leaving  the 
bubble  in  the  middle,  even  if  there  be  some  difference  in  the  diameter 
of  the  collars.  It  is  the  general  opinion  that  after  level,  Ys  and  cross- 
wires  are  adjusted,  the  instrument  must  be  correct.  This  is  by  no 
means  certain,  as  the  least  difference  in  the  size  of  the  collars  will 
throw  out  the  line  of  collimation  considerably.  This  difference  is  some- 
times found  in  new  instruments,  and  is  also  produced  by  unequal  wear,

denting,  etc.  It  is  therefore  advisable  that  the  equality  of  the  collars 
should  be  tested  from  time  to  time,  which  is  done  by  a  method  given 
further  on. 

2D  Adjustment. — To  piace  the  level  at  right-angles  to  the  vertical 
axis  of  the  instrument. 

Operation. — Turn  the  instrument  so  that  the  telescope  shall  stand 
over  the  line  of  two  opposing  leveling  screws,  and  bring  the  bubble 
to  the  center  of  the  tube;  then  turn  the  instrument  180  degrees  on  its 
center.  If  the  bubble  shows  any  displacement,  correct  one-half  of  it 
by  means  of  the  nuts  under  the  bar  at  the  Y  supports,  and  one-half  by 
the  foot-screws.    Several  trials  will  make  the  correction  perfect. 

3D  Adjustment. — To  place  the  cross-web  in  the  optical  axis  of 
the  telescope,  so  that  the  intersection  will  remain  on  an  object  in 
revolving  it. 

Operation. — Set  the  intersection  of  the  hairs  on  a  point  about  two 
hundred  or  three  hundred  feet  distant,  then  revolve  the  telescope  in 
its  Ys  half-way,  so  as  to  have  the  level  case  on  top.  If  the  wires  have 
moved  from  the  point,  bring  them  back  one-half  of  the  amount  of  the 
displacement.    Try  again,  and  repeat  the  operation  if  necessary. 

The  eye-piece  may  then  be  properly  aligned  and  directed  by  the 
four  black  capstan-headed  screws  (nearest  the  eye-end  of  the  tele- 
scope), so  that  the  field  of  view  shall  appear  evenly  divided  by  the 
cross-hairs,  as  already  explained. 

In  this,  as  well  as  in  any  other  telescope,  we  assume  that  the  tubes 
are  straight,  the  object-glass  well  centered,  and  the  slide  well  fitted. 
If  such  be  not  the  case,  the  telescope  can  only  be  adjusted  for  certain 
distances.  It  is  urged  by  some  makers  that  it  is  almost  impossible 
to  produce  straight  tubes,  and  that,  therefore,  the  object-slide  must 
be  adjustable.  This,  however,  is  entirely  erroneous.  Perfectly  straight 
tubes  can  be  made,  if  the  necessary  time  and  money  be  expended,  which 
is  the  only  requisite.  In  a  great  many  instruments  sold  today,  you  will 
find  that  the  object-glass  is  not  centered,  that  the  slide  is  poorly  fitted, 
and  that  all  these  inaccuracies,  which  are  not  apparent  at  a  glance, 
prove  more  injurious  than  ever  if  the  tubes  are  not  quite  straight.  It 
must  also  seem  clear  to  any  one  that  the  constant  working  of  the  slide 
in  an  adjustable  ring  would  loosen  the  screws  and  cause  considerable 
annoyance. 

Parallax  is  adjusted  by  moving  the  eye-piece  in  or  out  until  a 
clear  and  distinct  view  of  the  cross-hairs  is  obtained,  as  in  the  case  of 
the  transit  already  described.

The  Collar  Tkst. — After  the  instrument  is  properly  adjusted, 
the  equality  of  the  collars  may  be  ascertained  in  the  following-  manner: 

Operation. — Make  two  bench-marks,  place  the  instrument  exactly 
midway  between  them,  and  find  their  true  difference  of  level  by  reading 
leveling  rods  set  upon  them.  Now  place  the  instrument  near  one  of 
the  bench-marks  and  read  the  rods  again.  If  the  difference  of  the 
reading  is  equal  to  the  true  difference  of  level,  the  collars  are  of  equal 
diameter,  and  the  line  of  collimation  is  at  right-angles  to  the  vertical 
axis  of  the  instrument.  This  test,  once  made,  holds  good  ever  after, 
as  it  shows  that  the  collars  are  true,  and  consequently  that  a  correct 
adjustment  is  assured  of  all  its  other  parts,  as  already  described.  But 
it  need  hardly  be  mentioned  that  denting,  the  settling  of  sand  particles 
and  unequal  wear  will  also  affect  the  adjustment  in  the  same  manner. 

If  the  test  shows  that  the  line  of  collimation  is  not  perpendicular 
to  the  line  of  the  vertical  center,  then  the  collars  are  of  unequal  diame- 
ter, and  the  instrument  is  really  nothing  more  or  less  than  a  dumpy 
level,  as  this  defect  deprives  it  of  all  the  advantages  for  an  easy  and 
convenient  adjustment,  which  characterizes  the  Y-level  in  comparison 
with  the  dumpy. 

This  defect  may,  however,  be  temporarily  remedied  or  adjusted 
in  the  same  manner  as  the  line  of  collimation  in  the  dumpy  level  is 
adjusted,  but  it  must  ever  thereafter  remain  permanently  in  its  Ys, 
as  it  would,  if  reversed  end  for  end,  double  the  error  which  existed 
previous  to  this  adjustment. 

The  correction  may  also  be  made  by  displacing  the  horizontal 
cross-hair  to  the  extent  that  the  line  of  collimation  shall  be  truly  hori- 
zontal and,  at  the  same  time,  parallel  with  the  axis  of  the  spirit  .level  ; 
but,  in  that  event,  there  will  be  no  longer  any  agreement  with  the  optical 
axis,  which  again  gives  rise  to  a  number  of  inaccuracies  that  cannot 
be  obviated. 

A  Y-level,  in  order  to  deserve  that  name  at  all,  must  have  equal 
diameters  of  its  collars ;  and  if  that  is  not  found  after  a  crucial  test, 
the  instrument  maker  should  be  called  upon  to  remedy  this  dis- 
crepancy. 

No  doubt  can  possibly  exist  in  the  mind  of  any  engineer  of  the 
absolute  necessity  of  the  collar  test.  Considering  the  required  parallel- 
ism of  the  axis  of  collimation  and  the  axis  of  the  spirit  level,  he  must 
know  that  a  contact  can  only  be  made  between  telescope  and  Ys  by 
means  of  the  collars,  whose  exteriors  may  either  be  parts  of  the  surface 
of  a  cylinder,  or  that  of  a  cone,  and  that  the  required  parallelism  is

only  possible  in  the  former  case.  If  one  collar  exceed  the  other  in 
diameter,  the  centered  level  bubble,  if  reversed  in  the  Ys,  will  indicate 
a  displacement  corresponding  to  four  times  the  angle  intercepted  be- 
tween the  collar  axis  and  that  of  the  spirit  level.  No  further  demon- 
stration of  this  fact  is  necessary. 

Of  the  Dumpy  Level. 

In  principle,  the  same  laws  govern  the  requirements  of  the  dumpy 
that  hold  good  in  .the  Y-level.  Although  its  construction  differs,  the 
condition  of  its  line  of  collimation,  optical  center  and  level  vial  must 
be  such  as  to  bear  that  universal  relation  to  each  other  which  we  have 
fully  explained  in  the  other  instruments.  It  is  not  difficult  to  make 
all  the  necessary  adjustments  properly,  although  it  may  not  appear 
quite  so  handy  to  correct  its  errors  as  in  the  case  of  the  Y-level. 
Once  adjusted,  however,  the  instrument  will  remain  so  for  a  long  time, 
and  it  will  give  the  operator  considerable  satisfaction,  if  used  with  the 
ordinary  care. 

The  adjustments  of  the  level,  and  the  telescope  for  collimation, 
will  now  be  briefly  mentioned. 

Put  on  the  sun-shade,  and  focus  the  eye-piece  until  the  hairs  are 
distinctly  visible  and  the  parallax  destroyed ;  then  proceed  as  follows : 

Operation. — Turn  the  instrument  so  that  the  telescope  shall  stand 
directly  over  the  line  of  two  opposing  leveling  screws,  and  draw  the 
bubble  to  the  middle  of  the  tube  by  means  of  the  foot-screws.  Then 
turn  the  instrument  on  its  center  180  degrees,  and  if  the  bubble  remain 
centered  the  adjustment  is  perfect.  Any  displacement,  however,  will 
have  to  be  corrected  by  taking  up  one-half  of  it  with  the  capstan-headed 
screws  attached  to  the  level  case,  and  the  other  half  by  the  foot-screws. 
This  operation  must  be  repeated  several  times,  in  directions  normal  to 
each  other — that  is,  over  one  set  of  opposing  foot-screws  as  well  as 
over  the  other,  until  the  telescope  may  be  swung  in  any  position  and 
the  bubble  will  remain  in  the  middle.  See  that  the  adjusting  screws 
of  the  level  vial  are  firm,  yet  avoid  all  unnecessary  force  in  tightening 
them;  all  cramming  is  injurious,  and  tends  to  destroy  the  proper 
degree  of  refinement  required. 

After  having  set  the  diaphragm  so  that  the  cross-hairs  shall  be 
absolutely  horizontal  and  vertical,  which  is  easily  done  by  loosening 
the  capstan-headed  screws  and  turning  the  diaphragm  slightly,  being 
guided  by  some  point  bisected  by  the  horizontal  hair,  we  now  proceed 
to  adjust  the  cross-hair,  which  must  be  brought  into  the  collimation 
line.     Several  methods  are  known ;  the  one  which  is  always  available, 

Page  56

however,  is  that  by  means  of  stakes  and  level-readings  upon  them,  and 
it  is  to  this  that  we  shall  confine  ourselves  here. 

Operation. — Choose  a  piece  of  ground  nearly  level,  set  up  the 
instrument  and  center  the  bubble.  Drive  a  stake  (point  i)  firmly,  say 
two  hundred  or  three  hundred  feet  from  the  instrument,  in  any  con- 
venient direction  therefrom.  Hold  the  level  rod  upon  it  and  take  a 
reading.  Now  point  the  telescope  in  the  opposite  direction,  the  bubble 
being  centered,  and  plant  another  stake  (point  2)  at  the  same  distance 
from  the  dumpy,  driving  it  until  the  rod  shall  read  the  same  as  upon 
the  first  point.  These  two  stakes  are  on  the  same  level.  Now  set  up 
the  instrument  abount  ten  or  fifteen  feet  from  the  first  stake,  and  bring 
the  bubble  to  the  center;  take  a  rod-reading  on  point  1,  and  then  on 
point  2.  If  the  two  readings  are  alike,  with  a  truly  centered  bubble, 
the  hair  is  collimated.  If  there  is  any  difference,  take  up  nearly  ah 
of  it  by  moving  the  diaphragm  with  the  cross-hairs  either  up  or  down, 
as  already  explained.  Repeat  this  operation  until  the  readings  on 
points  1  and  2  are  identical,  when  the  instrument  is  in  adjustment. 

The  vertical  hair  is  of  no  particular  importance. 

With  these  precautions,  a  dumpy  level  may  be  made  absolutely 
accurate,  and  there  is  no  reason  why,  for  any  of  the  land  surveyors, 
and  for  nearly  all  of  the  engineer's  work,  this  compact  and  steady 
instrument  should  not  meet  every  requirement.  We  frequently  discuss 
its  merits  with  our  customers,  and  have  never  hesitated  to  recommend  it. 

Test  of  Telescopes  in  General. 

If  a  telescope  is  to  be  tested  for  its  qualities,  make  sure  that  all  its 
lenses  are  perfectly  clean. 

To  test  for  definition,  use  small,  clear  print,  and  view  it  from  a 
distance  of  from  thirty  to  fifty  feet.  If  the  print  appears  clear  and 
well  defined,  and  fully  as  legible  at  this  distance  as  if  viewed  with  the 
naked  eye  at  the  distance  of  distinct  vision,  the  surfaces  of  the  object- 
glass  are  perfect  and  well  finished.  If,  on  the  contrary,  the  print  ap- 
pears dull  and  indistinct,  and  the  finer  details  illegible,  or  even  invisible, 
the  surfaces  are  imperfect  and  faulty,  for  the  rays  proceeding  from 
the  various  points  of  the  object  are  not  refracted  to  their  correspond- 
ing points  in  the  image. 

Indistinctness  may  be  caused  by  spherical  aberration. 

To  test  this,  cover  the  object-glass  with  a  ring  of  black  paper, 
reducing  the  aperture  to  one-half ;  again  focus  small  print  to  distinct 
vision;  remove  the  ring  of  black  paper  and  cover  the  center  of  the 
object-glass  (previously  left  open),  then  mark  how  much  the  object- 

Page  57 


THE  A.  LIETZ  COMPANY  ^^o^Sf^ 

SAN  FRANCISCO,  U.  S.  A. 

glass  has  to  be  moved  in  or  out  for  distinct  vision.  If  the  spherical 
aberration  has  been  reduced  to  a  minimum,  very  little,  if  any,  slide  mo- 
tion is  necessary  to  obtain  a  distinct  view  under  both  tests.  The  amount 
of  movement,  however,  constitutes  a  measure  for  the  spherical  aberra- 
tion of  the  object-glass. 

Another  test,  but  not  as  good  as  the  one  just  mentioned,  is  to  focus 
an  object  to  distinct  vision ;  then  slide  the  object-glass  in  or  out,  observ- 
ing at  the  same  time  the  quantity  of  motion  necessary  to  render  the  object 
indistinct.  If  the  spherical  aberration  is  completely  corrected,  the  object 
should,  theoretically,  be  rendered  indistinct  by  the  slightest  motion  of 
the  lens  ;  but,  practically,  this  is  not  the  case,  as  the  eye  will  accommodate 
itself  in  a  measure  to  the  difference  of  divergence  of  the  rays,  caused 
by  the  motion,  in  or  out,  of  the  object-glass,  in.  the  same  manner  as  it 
will  accommodate  itself  to  near  and  distant  objects  when  viewing  with- 
out the  aid  of  lenses.  So,  if  the  image  formed  by  a  perfect  object-glass 
is  viewed  by  another  perfect  lens  of  long  focal  length,  say  six  inches, 
the  object-glass  might  be  moved  in  or  out  one-fourth  of  an  inch  from 
the  point  of  distinct  vision,  and  the  object  will  still  appear  compara- 
tively clear,  as  the  one-fourth-inch  motion,  with  an  eye-lens  of  such 
long  focal  length,  cannot  cause  enough  difference  in  the  divergence  of 
the  rays  to  prevent  the  accommodation  of  most  eyes  to  it.  The  shorter 
the  focal  length  of  the  eye-lens,  the  more  rapid  will  be  the  change  of 
divergence  or  convergence  of  the  rays  with  a  certain  amount  of  motion ; 
therefore,  the  second  test  is  only  applicable  with  eye-pieces  of  very 
high  power,  which,  at  the  slightest  motion  in  or  out,  will  cause  a 
sufficient  amount  of  divergence  of  the  rays  to  prevent  the  accommoda- 
tion of  the  eye  to  the  change. 

To  test  the  chromatic  aberration,  either  a  celestial  body  or  a  white 
disc  should  be  selected  for  an  object. 

Focus  the  object  to  distinct  vision,  thereupon  move  the  object-glass 
slowly  in  and  out  alternately.  If,  in  the  first  instance,  a  light  yellow 
ring  is  seen  at  the  edge  of  the  object,  and  in  the  second  one  a  ring  of 
purple  light,  the  object-glass  may  be  considered  perfect,  as  it  proves 
that  the  most  intense  colors  of  the  prismatic  spectrum  (orange  and 
blue)  are  corrected. 

To  test  the  flatness  of  field,  take  a  square,  flat  object,  the  sides  of 
which  are  about  four  inches  long  and  perfectly  straight — the  best  object 
is  a  heavily-lined  square,  drawn  on  white  paper  with  india  ink.  Sight 
this  object  from  such  a  distance  that  it  will  nearly  fill  the  field  of  view 
of  the  telescope,  and  see  if  it  still  appears  flat  and  its  sides  perfectly 

Page  58

SAN  FRANCISCO,  U.  S.  A. 

straight;  if  so,  the  telescope  is  a  good  one.  If,  on  the  contrary,  the 
object  appears  distorted,  I.  c,  if  the  sides,  instead  of  being  straight, 
form  curves  and  the  surfaces  appear  concave,  instead  of  flat,  the  tele- 
scope is  not  good,  for  it  shows  that  the  proportions  of  foci,  aperture 
and  distances  between  the  different  lenses  are  not  according  to  the  laws 
of  optics ;  owing,  generally,  to  the  attempt  to  force  the  magnifying 
power  beyond  its  limits. 

As  all  the  refractions  of  light  in  the  telescope  are  caused  by  flat 
and  spherical  surfaces,  it  is  evident  that  the  edge  of  a  round  flat  object, 
when  used  for  the  above  test,  cannot  be  distorted,  but  that  the  surface 
only  will  appear  concave  to  a  keen  observing  eye.  A  telescope  which 
distorts  the  image  to  a  perceptible  degree  will  not,  however,  cause  any 
errors  in  common  use,  if  only  one  point  in  the  lens  is  taken  in  all  ob- 
servations, but  it  is  decidedly  objectionable  in  stadia  measurements, 
where  two  points  in  the  field  of  view  are  used  at  the  same  time. 

To  Find  the  Magnifying  Power  of  a  Telescope. 

A  practical  method  for  finding  the  magnifying  power,  available  to 
anyone,  which  does  not  require  any  apparatus,  taking  up  only  a  few 
moments'  time,  is  the  following: 

Set  up  the  instrument,  and  about  twenty  or  thirty  feet  therefrom 
hold  up  a  graduated  rod.  Observe  the  rod  with  one  eye  by  direct 
vision,  and  with  the  other  through  the  telescope.  Assume  a  certain 
space  on  the  rod,  say  the  height  of  a  numeral,  or  two  sharply  drawn 
lines,  and  count  the  number  of  divisions  on  the  rod  in  that  space ;  then 
observe  the  number  of  divisions  that  are  seen  by  the  naked  eye  in  the 
same  space  enlarged.  The  ratio  between  the  two  is  the  power  sought. 
It  is  the  reading  of  a  magnified  space  of  known  length  on  the  graduated 
face  of  the  rod.  With  a  little  practice  both  eyes  will  be  able  to  distin- 
guish the  rod  divisions  at  the  same  time.  If  what  is  known  to  be  o.i 
of  a  foot,  is  enlarged  by  viewing  it  through  a  telescope  so  as  to  cover 
the  space  of  2.4  feet  as  seen  by  the  unaided  eye,  the  magnifying  power 
is  24  for  the  distance  in  focus.  The  real  power  is  somewhat  less,  for 
as  the  tube  of  the  telescope  is  drawn  out  for  near  objects,  the  power 
necessarily  increases.  The  magnifying  power  obtained  by  this  method 
holds  good  for  the  distance  that  the  rod  can  be  read  by  the  unaided 
eye,  and  it  is  always  somewhat  greater  than  the  actual  power. 

For  a  very  accurate  determination  of  the  magnifying  power,  it  is 
necessary  to  ascertain  the  focal  length  of  the  objective  and  that  of  the 
eye-piece,  in  order  to  compare  them  and  to  find  their  proportion.  While 
the  former  is  easily  obtained  by  a  direct  measurement  from  the  objective

lens  to  the  cross-hairs,  the  latter,  usually  containing  an  entire  system 
of  lenses,  presents  numerous  difficulties.  For  this  purpose  we  possess 
an  apparatus  especially  designed  for  us. 

Dividing  the  focal  length  of  the  objective  (when  the  telescope  is 
focused  to  mean  distance)  in  millimeters,  by  the  equivalent  gives  the 
magnifying  power  of  the  telescope  under  consideration. 

If  any  of  our  customers  want  the  focal  length  of  an  eye-piece  deter- 
mined, we  shall  cheerfully  do  so,  without  charge,  upon  receipt  of  it, 
which  should  be  sent  carefully  packed. 

Adjustments  of  the  Plane-Table  Alidade. 

Without  going  again  into  all  the  details  of  instrumental  adjust- 
ments, it  behooves  us  to  enumerate  the  points  required  of  this  instru- 
ment when  in  proper  condition.    These  are: 

1st — That  the  fiducial  edge  of  the  rule  be  absolutely  straight; 

2d — That  all  parallax  be  destroyed,  by  placing  the  cross-hairs  in 
proper  focus ; 

3d  — That  the  line  of  collimation  move  in  a  vertical  plane ; 

4th — That  this  plane  be  normal  to  the  plane  of  the  ruler ; 

5th — That  the  same  plane  also  intersect  the  fiducial  edge  of  the 
ruler,  or  at  least  be  parallel  thereto ; 

6th — That  during  parallelism  of  the  optical  axis  and  the  fiducial 
edge,  the  zeros  of  the  vertical  arc  and  its  vernier  correspond. 

This  instrument  is  used  in  the  topographical  departments  of  the 
U.  S.  Coast  and  Geodetic  Survey,  and  the  U.  S.  Geological  Survey,  and 
is  exclusively  applied  in  mapping  the  topographical  features  of  the 
country  in  Europe,  usually  by  officers  of  the  army,  who  control  these 
surveys,  after  the  triangulation  points  have  been  established. 

This  method  of  surveying  has  been  constantly  improved  in  prac- 
tice, particularly  by  the  experts  of  the  Geological  Survey,  and  it  may 
be  safely  said  that,  with  the  required  accuracy,  nothing  surpasses  it  for 
small-scaled  work  in  speed  and  application.  All  the  bulky  parts  of  the 
table  have  been  reduced  to  a  minimum,  so  that  it  may  be  handled  with 
comparative  ease  in  the  roughest  mountain  country. 

We  refer  our  readers  to  appendix  No.  22  of  the  Coast  Survey 
Report  of  1865,  which  may  be  had  separately  in  bound  book  form,  called 
The  Plane-Table  and  its  Uses,  as  an  excellent  theoretical  and  practical 
treatise  of  this  interesting  subject.    Price  $2.00.

MODERN  ENGINEERS'  AND  SURVEYORS' 
INSTRUMENTS 


AS   MADE   BY 


THE  A.  LIETZ  COMPANY 


INTRODUCTION 

The  following  illustrations  show  the  principal  articles  we  manu- 
facture, being,  in  the  case  of  this  section,  almost  exclusively  confined 
to  instruments  required  by  the  civil,  mining,  irrigation,  hydraulic  and 
military  engineer,  for  making  accurate  measurements  and  surveys  for 
any  purpose  whatever. 

Of  the  surveying  instruments  each  illustration,  or  plate,  is  com- 
plete within  itself.  Every  feature  is  carefully  noted,  together  with  the 
price  and  a  general  description  in  a  condensed  form.  The  additional 
accessories  that  may  be  had  in  each  instance  are  also  enumerated  and 
their  prices  given.  It  is  well,  however,  that  the  engineer  should  con- 
sult the  preceding  part  of  this  Manual,  wherein  every  detail  is  care- 
fully described  and  extensively  discussed.  If  pains  are  taken  to  look 
this  over,  the  reader  will  obtain  such  information  as  would  be  given 
him  in  the  salesroom. 

Every  article  has  been  numbered,  and  by  these  numbers  our  cus- 
tomers may  order,  without  going  into  a  minute  description  of  the 
articles  wanted.    For  example  : 

"Send  me  transit  No.  4  (1919),  with  the  following  extras " 

is  all  that  is  required  to  designate  to  us  exactly  what  is  desired  by  our 
patron. 

In  ordering  please  mention  the  issue  of  the  catalogue,  as  the  num- 
bers of  preceding  issues  necessarily  conflict. 

See  also  Telegraph  Code  on  pages  66  and  67. 

With  the  detailed  information  on  its  succeeding  page,  every  plate 
becomes  a  complete  price  list  of  the  particular  instrument  illustrated. 
Every  effort  has  been  made  to  make  this  part  of  the  book  as  intellig- 

Page  64

SAN  FRANCISCO,  U.  S.  A. 

ible  a-  possible,   without  the  necessity   of  searching  over  numerous 
pages  to  gather  information. 

Although  we  shall  make  any  instrument  of  precision  called  for, 
we  desire  to  state  clearly  that  we  have  made  a  particular  specialty  of 
engineers'  and  surveyors'  instruments,  because  there  is  for  them  alone 
a  demand  at  the  present  time,  and  for  this  reason  our  shop  facilities 
have  been  especially  designed  and  improved  for  the  manufacture  of 
these  articles. 

If  instruments  for  a  more  scientific  purpose  are  wanted,  for  astro- 
nomical or  geodetic  work,  for  instance,  we  can  either  make  them  on  a 
special  order,  or  we  can  import  them  for  our  customer,  having  made 
arrangements  in  Europe  which  enable  us  to  sell  such  instruments  as 
cheaply  as  anyone  in  the  United  States.  For  institutions  of  learning 
we  import  without  payment  of  duty. 

All  our  products  have  been  priced  commensurate  with  their  quality 
and  deductions  are  not  made  from  our  price  list,  which  agrees  favor- 
ably in  all  its  quotations  with  those  of  the  best  Eastern  firms. 

^'e  furnish  a  first-class  article  at  a  fair  price,  and  our  goods 
stand  upon  their  individual  merit.  It  has  been  our  object  to  create  the 
best  that  the  instrument  maker's  art  can  make  or  devise,  and  with  the 
records  of  the  past  decades  before  us  we  feel  that  we  have  been  suc- 
cessful in  every  way.

(Double  Spindle  Repeating) 
Nos.  1  to  12 

These  are  elegant  instruments,  absolutely  accurate  in  all  work- 
ing parts,  designed  for  land  surveying  and  engineering  work  of  a 
high  character  and  are  guaranteed  in  every  detail. 

The  general  dimensions  are  given  to  the  right  of  each  illus- 
tration, as  well  as  the  price,  and  the  extras  that  may  be  had  upon 
application.  By  carefully  inspecting  the  plates,  the  price  list  and 
the  enumerated  extras,  the  purchaser  is  enabled  to  choose  the 
article  and  any  desired  accessory,  and  make  an  estimate  of  its  cost. 

We  make  each  style,  if  desired,  in  hard  aluminum,  which  in- 
creases the  price  15  per  cent.

20  seconds,  two  double  verniers  being  provided,  placed  so  as  to 
afford  a  reading  without  stepping  aside.  The  vertical  arc  or  circle 
is  graduated  to  read  to  60  or  30  seconds.  Each  instrument  has 
long  compound  centers,  shifting  plates  on  tripod  head,  with  new 
improved  coupling.  The  telescope  possesses  definition,  light  and 
power  in  a  high  degree.  It  has  the  best  lenses,  achromatic  ob- 
jective and  eye-piece.  Erect  vision.  The  telescope  is  reversible

THE  LIETZ  TRANSIT   THEODOLITES 

WITH  UNITED  STANDARDS,  "PATENTED" 

Your  attention  is  called  to  the  additional  features  incorporated  in  this 
instrument,  consisting  of  a  "Unifier"  and  a  one-piece  casting  of  the  top 
plate  and  "U"  shaped  standards,  so  constructed  as  to  permit  of  a  larger  cir- 
cular compass.

THE  LIETZ  PATENT  UNIFIER 

The  "Unifier"  is  a  rigid  rod  looped  in  the  center  to  clear  the  line 
of  sight,  connecting  both  standards  firmly,  thereby  securing  lateral 
rigidity  and  avoiding  stress  in  a  degree  heretofore  unknown.  (See  cut 
with  telescope  removed.) 

The  telescope  revolves  around  the  "Unifier,"  and  its  pivots  are 
cylindrical,  resting  in  "V"  shaped  bearings  which  secure  the  refine- 
ment of  motion  in  a  vertical  plane  necessary  for  precise  work. 

Its  characteristics  insure  the  greatest  stability  and  permanency  of 
adjustments  with  less  liability  of  injury.  All  the  adjustments,  as  well 
as  the  manipulations,  are  the  same  as  in  other  instruments. 

This  transit  has  been  given  practical  field  tests  for  several  years, 
which  justifies  its  recommendation  as  a  very  superior  article. 

This  type  of  instrument  was  used  with  marked  success  and  high 
satisfaction  on  the  work  of  the  Hetch  Hetchy  undertaking  in  Califor- 
nia ;  also  by  the  Marin  Municipal  Water  District  on  the  tunnel  through 
Mt.  Tamalpais,  California.  Too  much  cannot  be  said  of  the  service- 
ability of  this  type  of  construction  in  instruments.

LIETZ   TRANSIT   THEODOLITES 
With  U-shaped  Standards 
Instruments  of  very  superior  construction  and  design.    The  standards  upon  which  the  tele- 
scope rests  and  the  upper  plate  are  cast  in  one  U-shaped  piece,  thus  affording  far  more  strength 
than  the  ordinary  form. 

The  telescope  is  reversible  in  position,  as  well  as  exchangeable  in  its  bearings,  which  are  pro- 
vided with  dust  caps  and  screws,  to  give  them  the  proper  friction.  The  telescope  is  either  erect 
or  inverting.  For  reasons  already  set  forth  (see  page  24)  the  inverting  form  should  be  given 
the  preference.  The  telescope  possesses  the  finest  lenses  and  optical  accessories.  It  has  a  slide 
protector  and  is  provided  with  a  sun  shade.  The  cross  hairs  are  focused  by  a  screw  motion  of  the 
eye-piece.

SURVEYORS'  INSTRUMENTS

LIETZ   MOUNTAIN   AND   MINING   TRANSITS 
"ALUMINUM" 

The  illustrations  on  pages  84  and  88  represent  our  Mountain  and 
Mining  Transits  Nos.  9  and  12.  While  with  the  introduction  of  our 
special  aluminum  alloy  we  have  been  the  producers  of  the  lightest  in- 
struments for  years,  yet  some  of  our  patrons  have  expressed  a  desire 
to  possess  an  instrument  of  smaller  size,  admitting  of  easier  transpor- 
tation in  mountainous  country.  These  transits  are  made  with  as  much 
care  as  our  larger  instruments ;  the  constructive  details  are  similar, 
and  full  reliance  may  be  placed  upon  the  instruments  as  to  the  per- 
formance of  their  working  parts  in  every  respect.  We  would  espe- 
cially recommend  our  friends  to  order  these  instruments  in  our  special 
aluminum  alloy,  which  not  only  makes  them  lighter,  but  adds  consider- 
ably to  the  rigidity,  lateral  strength,  and  to  their  steadiness.  This 
statement  is  made  and  based  upon  our  experience  gained  in  over 
twenty  years,  during  which  time  we  have  manufactured  more  than 
one  thousand  instruments  of  our  special  aluminum  alloy,  and  it  is  veri- 
fied by  authorities  who  constantly  use  them.  At  first  thought  the  state- 
ment may  seem  paradoxical  that  an  instrument  made  of  lighter  mate- 
rial should  be  steadier  than  one  made  of  heavier  metals,  and  we  are 
constantly  confronted  with  queries  from  engineers,  when  we  recom- 
mend instruments  of  the  lighter  type,  whether  these  will  prove  steady 
enough  in  the  wind.  It  seems  that  the  ordinary  opinion  is  not  based 
upon  practical  experience  but  created  by  the  reasonable  assumption 
that  heavier  weight  will  offer  more  resistance  to  disturbing  influences 
than  light  weight. 

While  it  cannot  be  denied  that  the  weight  of  an  instrument  adds 
to  its  steadiness,  it  must  be  borne  in  mind  that  instruments  have  not 
been  made  of  the  older  metals  in  order  to  gain  steadiness,  but  simply 
because  this  was  the  best  material  available  for  the  purpose.  Wear  and 
resistance  in  case  of  accident  were  the  principal  features  sought.  A 
light  material,  provided  it  has  these  qualities,  offers  the  best  oppor- 
tunity to  produce  the  most  rigid  instrument,  for  the  reason  that  it  ad- 
mits of  lowering  the  center  of  gravity  by  a  judicious  distribution  of 
the  metals,  and  this  is  what  we  have  aimed  at  and  believe  we  have 
fully  accomplished  in  our  aluminum  alloy  instruments.  These  instru- 
ments are  rigid  and  firm ;  they  offer  more  resistance  in  case  of  a  fall 
than  the  heavier  metals ;  the  wearing  qualities  are  such  that  no  bush- 
ing is  required ;  the  coefficient  of  expansion  and  contraction  is  elim- 
inated, so  that  their  adjustments  will  remain  constant  under  severe 
conditions.  Their  qualities  during  the  last  twenty  years  have  been  so 
thoroughly  tested  that  we  conscientiously  recommend  them  to  the 
profession. 

It  must  be  apparent  that  there  cannot  be  any  great  difference  in 
price  between  a  large  and  a  small  sized  instrument.  The  workmanship 
in  each  is  alike,  and,  if  anything,  more  complicated  and  costly  in  the

smaller.  The  only  difference  is  in  the  quantity  of  metal  used,  but,  as 
this  cannot  possibly  amount  to  much  in  price,  it  is  more  than  compen- 
sated for  by  the  additional  care  required  in  handling  the  smaller  parts. 
This  explanation  would  hardly  seem  necessary,  were  it  not  for  the 
prevailing  impression  that  all  merchantable  articles  of  the  same  kind 
shall  be  rated  by  their  respective  sizes.  That  this  cannot  obtain  in  the 
case  of  instruments  must  stand  to  reason.  The  price  of  a  transit  can 
only  be  reduced  by  omitting  certain  features,  or  by  changing  it  to  a 
simpler  construction.

LIETZ   BUILDERS'    LEVELS    Nos.  21  to  21 BC 

As  made  by  ns  for  the  use  of  architects,  builders,  contractors,  and  for 
general  engineering  work  not  requiring  the  highest  degree  of  accuracy,  the 
instrument  is  constructed  along  the  same  lines  as  our  No.  20  Precision 
Dumpy  Level,  and  therefore  not  liable  to  get  out  of  order,  an  important 
feature,  because  instruments  of  this  kind  occasionally  have  to  be  intrusted 
to  men  whose  duties  will  not  admit  of  the  greatest  amount  of  care.  The 
instrument  is  far  superior  to  the  so-called  architects'  level,  which  is  built  on 
the  principle  t>f  the  Y-level,  and  in  which  novelties  are  usually  embodied  to 
attract  the  buyer  and  which  tend  to  make  instruments  complicated  and  un- 
reliable, difficult  to  manipulate,  and  which  usually  decrease  their  strength 
considerably.  Our  instrument  No.  21  is  built  for  the  special  purpose  of  ob- 
taining the  simplest  form  of  an  accurate  and  reliable  tool  and  is  offered  to 
the  profession  as  an  instrument  of  efficiency  at  a  very  moderate  price.

LIETZ  PRELIMINARY  TRANSIT  No.  22 

For  many  purposes  where  great  accuracy  is  not  required,  it  is  often 
far  more  convenient  to  use  some  small  instrument  which  will  admit  of 
measurements  within  practical  limits.  The  irrigator,  farmer,  ditcher, 
grader,  building  contractor,  gardener,  forester,  road  builder,  etc.,  often 
require  means  of  obtaining  heights  and  relative  positions,  for  which 
higher  grade  instruments  would  be  unnecessarily  refined. 

It  is  for  such  purposes  that  we  have  constructed  the  Lietz  Pre- 
liminary Transit.  This  combines  portability  with  accuracy  and  relia- 
bility, within  a  reasonable  limit,  at  a  minimum  expenditure.  In  appear- 
ance it  is  identical  to  an  engineer's  transit.  It  possesses  four  leveling 
screws,  but  no  shifting  center.  The  lower  axis  moves  in  the  star  piece 
which  carries  the  four  leveling  screws.  It  is  readily  clamped  in  any 
position  by  means  of  clamp  and  tangent  screws.  The  second  spindle 
carries  the  top  plate,  together  with-  the  standards  and  telescope.  The 
compass  is  centrally  located,  and  has  a  diameter  of  three  inches.  The 
plate  is  graduated  in  the  regular  way,  and  this  graduation  is  utilized 
for  reading  horizontal  angles  by  means  of  a  vernier  to  two  minutes 
of  arc.  The  vertical  arc  is  graduated  from  0  degree  to  100  degrees 
each  way,  reading  to  two  minutes  by  a  vernier  which  is  clamped  readily 
into  any  position  on  the  telescope  axis  by  a  milled-head  screw,  so  that 
the  position  of  the  arc,  which  is  stationary  on  the  standard,  admits  of 
reading  any  vertical  angle,  by  means  of  repetition,  if  over  90.  The 
telescope  is  six  inches  long,  has  erect  lenses,  magnifying  eight  diam- 
eters. The  telescope  possesses  a  level  two  and  one-half  inches  in  length, 
and  a  tangential  movement,  so  that  the  instrument  represents  a  com- 
plete transit  of  modern  construction,  having,  of  course,  a  limited  de- 
gree of  accuracy,  but  capable  of  carrying  out  preliminaries  where  high- 
grade  instruments  would  otherwise  have  to  be  used.  Every  feature  of 
the  transit  is  represented  here,  and  it  admits  of  obtaining  results  ap- 
proaching those  of  the  surveyor's  transit  and  level. 

Crude  instruments  are  placed  on  the  market  to  supply  the  demand 
for  a  fairly  reliable  measuring  tool  of  small  cost.  These  are  usually 
worthless,  as  they  are  made  without  any  regard  for  the  underlying 
principles  that  should  govern  the  make  of  such  an  article.  But  with  the 
Lietz  Preliminary  Instrument,  for  which  patent  has  been  granted,  the 
object  has  been  attained.  Every  part  is  carefully  made  and  neatly  fin- 
ished, and  its  cost  is  less  in  comparison  than  the  inferior  articles  usually 
offered  for  sale  in  the  market.

Our  many  years  of  experience  brought  us  to  the  conclusion  that  many 
classes  of  work,  especially  undertakings  of  comparatively  short  duration, 
do  not  necessarily  require  instruments  made  with  that  degree  of  refine- 
ment that  characterizes  our  "Precision  Line."

LIETZ  PLANE  TABLE  OUTFITS 


The  advantages  of  the  Plane  Table  for  topographic  surveying  and  map- 
ping has  brought  this  instrument  into  very  popular  favor,  especially  in  our 
irrigation  districts  and  oil  fields. 

A  planchette  or  drawing  board  is  mounted  upon  a  specially  constructed 
tripod  head.  The  Johnson  Movement  consists  of  a  socket  with  a  flange  to 
which  the  board  is  fastened.  This  socket  is  engaged  and  held  by  three 
segments  in  a  manner  to  admit  of  the  orientation  of  the  planchette  and  also 
the  clamping  of  it  by  means  of  a  large  milled  head  screw. 

The  Lietz  Tangent  Head  Tripod  (page  120)  is  an  improved  form.  While 
it  entails  the  additional  investment  it  is  self-evident  that  its  nicety  of  adjust- 
ment and  its  control  of  the  planchette  is  a  labor-saving  feature,  it  being  con- 
structed with  the  clamp  and  tangent  in  azimuth  and  the  three  screws  for 
leveling. 

We  offer  several  forms  or  modifications  of  Alidades. 

Our  No.  30  represents  a  type  as  made  for  many  years  to  meet  the  needs 
of  the  topographer,  whereas  No.  31  exemplifies  the  very  latest  form  as 
adopted  by  the  United  States  Geological  Survey.  Its  improvement  consists, 
briefly,  of  the  telescope  revolving  180  degrees  on  its  longitudinal  axis,  thus 
admitting  of  an  easy  adjustment  and  control  of  the  line  of  collimation,  and 
the  graduating  of  the  vertical  arc  on  the  periphery  for  convenience  in  reading 
the  angles,  and  its  manner  of  numbered  graduations.  With  the  index  of  the 
vernier  at  30  instead  of  0  it  can  readily  be  understood  that  all  the  angles 
as  read  are  positive,  overcoming  thereby  almost  all  possibility  of  error  in 
the  notes. 

Our  No.  32  is,  again,  a  modification  of  our  No.  31  and  is  after  the  model 
adopted  by  the  Geological  Department  of  the  Stanford  University.  Its  com- 
pactness and  resultant  portability  brought  us  .to  the  conclusion  that  it  would, 
likewise,  be  appreciated  by  the  members  of  the  profession.  Today  they  are 
in  use  in  many  of  our  States  and  especially  in  the  oil  districts  of  Oklahoma 
and  Texas  as  well  as  in  California.

TRIPODS  FOR  LIETZ  INSTRUMENTS 


Made  of  selected  ash,  straight  grained  and  well  seasoned.  Withstand 
unusual  use. 

Our  extension  tripods  are  very  rigid  and  strong  and  move  freely  under 
all  conditions  of  heat  and  cold.  The  double  clamps  employed  are  of  one- 
piece  cast  brass  and  will  not  break  under  ordinary  use.  We  furnish  many 
tripods  equipped  with  one  extension  leg,  which  admits  of  all  the  advan- 
tages of  the  extension  tripods  as  regard  set-ups,  their  only  disadvantage  be- 
ing lack  of  portability. 

We  call  special  attention,  however,  to  the  greater  steadiness  and  free- 
dom from  tremor  in  open  windy  country  of  our  straight  split-leg  tripod 
No.  38  as  furnished  with  our  precision  transits.  In  instruments  of  high 
power  and  sensitive  levels  it  is  the  only  tripod  to  be  recommended.  In  use 
in  cities  and  country  it  affords  quick  set-ups  and  easy  carrying.

No.  110 


No.  110  Godwin's  Improved  Portable  Heliograph.  The  improvement 
of  the  Godwin  type  lies  principally  in  that  it  necessitates  the 
need  of  but  one  tripod,  whereas  in  most  other  forms  two  are 
necessary. 

Illustration  "A"  shows  the  outfit  in  use  with  the  two  mirrors, 
which  are  required  in  order  to  get  the  reflected  sunlight  if  the 
sun  is  in  the  rear  of  the  operator.  Illustration  "B"  shows  the 
outfit  as  it  is  mostly  used  when  the  sun  can  be  reflected  directly 
to  the  station  to  be  signaled. 

Instrument  consists  of  two  mirrors,  3%x3%  inches,  adjust- 
able vertically  and  horizontally  by  micrometer  movements,  a 
shutter  4%x4%  inches,  a  sighting  rod,  and  one  tripod  24  inches 
high.  Instrument  fits  neatly  in  two  chamois-lined  trays,  con- 
tained in  leather  case  with  shoulder  strap.  Weight  of  entire

ANEROID   BAROMETERS 

In  connection  with  our  line  of  Barometers,  Barographs,  Thermographs, 

etc.,  we  desire  to  call  attention  to  the  importance  of  selecting  such  articles. 
We  aim  to  carry  only  the  most  reputable  makes  of  these  instruments. 

With  our  factory  facilities  ami  years  oi  experience  we  are  in  a  position 
to  offer  our  patrons  the  accommodation  ot'  testing  eacli  individual  instru- 
ment under  pressure  and  in  connection  with  a  standard  mercurial  barometer. 
thus  assuring  our  friends  of  that  satisfaction  seldom  enjoyed  when  pur- 
chasing through  other  sources. 

DESCRIPTION 

The  Aneroid,  owing  to  its  portable  form  and  great  sensitiveness  in  re- 
sponding to  changes  in  pressure  of  the  atmosphere  (it  will  denote  a  change 
much  quicker  than  the  Mercurial  Barometer),  is  today  in  more  general  use  by 
observers  of  meteorological  changes  than  any  other  form  of  Barometer. 

In  measuring  altitudes,  owing  to  its  portability,  sensitiveness  and  the 
ease  with  which  approximate  results  may  be  obtained,  it  is  highly  valuable 
to  the  Engineer  and  Surveyor,  while  the  Tourist,  with  the  Aneroid,  notes 
his  gain  in  elevation  foot  by  foot,  as  well  as  plans  his  excursions  in  accord- 
ance with   prognostications  from  its  readings. 

The  illustration  shows  the  general 
construction  of  the  movement  with  its 
elastic  metallic  box,  called  the  vacuum 
chamber. 

This  chamber  is  constructed  with 
two  circular  discs  of  thin  corrugated 
German  silver,  firmly  soldered  to- 
gether at  the  edges,  forming  a  close 
box.  The  air  is  exhausted  from  this 
box  which  causes  the  top  and  bottom 
discs  to  close  together. 

The  vacuum  chamber  is  firmly 
fixed  to  the  circular  metal  base  by  a 
post  upon  its  centre,  projecting 
through  the  base  plate. 

An  iron  bridge  spans  the  chamber, 
resting  upon  the  base  plate  by  means 
of  the  two  pointed  screws.  (These 
screws  are  used  to  finely  regulate  the 
tension  upon  the  chamber.) 
To  the  bridge  is  fixed  the  mainspring,  which  is  forced  down  by  mechan- 
ical means  sufficient  to  insert  a  knife  edge  piece. 

As  this  knife  edge'  is  fastened  (by  means  of  a  central  pillar)  to  the  top 
disc  of  the  chamber  the  mainspring,  when  released,  lifts  the  upper  part  of 
the  chamber,  drawing  the  two  discs  apart. 

As  this  forms  a  perfect  balance  (the  power  of  the  mainspring  opposing 
the  atmospheric  pressure  upon  the  vacuum  chamber),  any  variation  in  air- 
pressure  will  now  be  shown  by  a  movement  up  or  down  of  the  elastic 
chamber.  A  decrease  in  pressure  will  allow  the  mainspring  to  overcome 
the  power  of  the  vacuum,  the  action  then  being  upwards,  and  an  increase 
of  air  pressure  will  produce  the  contrary  result.

No.  320 


No.  325-326 


No.  320  U.  S.  Weather  Bureau  Standard  Rain  Gauge,  as  made  by  us, 
consists  of  a  funnel,  a  receiver,  overflow  and  a  measuring 
stick.  Gauge  25  inches  high,  funnel  8  inches  in  diameter. 
Each    

No.  321,  same  as  No.  320  but  13  inches  high,  funnel  3  inches  in 
diameter  

The  rain  collected  by  tile  funnel  flows  into  the  receiver,  which  is  of  smaller 
diameter  than  the  funnel  and  so  adjusted  that  the  readings  are  magnified  10 
times.  To  take  reading  insert  measuring  stick  through  the  funnel  into  the 
receiver  and  note  how  high  it  is  moistened.  The  sticks  are  graduated  in  lOths

To  measure  snow,  remove  the  funnel  and  receiver  and  after  collecting  let  it 
melt.  Then  pour  into  receiver  and  measure  same  as  rain.  Also  measure

The  Self-Registering  Rain  Gauge  has  a  receiver  8x8  inches.  The  rain  enters 
this  receiver  and  is  collected  in  a  bucket.  When  this  bucket  has  received 
1  /100th  of  an  inch  of  rain  it  tilts  over,  and  the  hand  registers  the  fall  as 
1 /100th  of  an  inch.  The  tilting  of  one  bucket  brings  another  in  position,  which 
when  filled  overbalances,  registers  and  brings  the  first  bucket  in  position  again. 
One  complete  revolution  of  the  large  hand  indicates  one  inch  of  rain  in 
l/100ths,  and  the  smaller  dial  registers  up  to  10  inches.

LIETZ   WATER   REGISTERS 

As  made  by  us  for  the  U.  S.  Department  of  Agriculture 


Lietz  Water 
Register  No.  360 

(Galvanized  Iron  Cover 
not  shown) 


The  Lietz  Water  Register,  for  auto- 
matically recording  the  rise  and  fall 
of  water  in  reservoirs,  lakes,  canals, 
weirs,  etc.,  was  originally  designed 
and  manufactured  by  us  for  the 
U.  S.  Department  of  Agriculture  over 
twenty  years  ago,  and  has  found  wide 
application.  Its  simplicity  of  con- 
struction, together  with  efficiency  and  moderate  price,  has  created  its  pop- 
ularity. We  have  made  improvements  from  time  to  time,  which  have 
increased  its  efficiency,  and  the  Register  as  made  by  us  today  constitutes 
the  best  moderate  price  device  on  the  market. 

The  customary  ratios  which  we  supply  and  aim  to  keep  in  stock  are 
1:1,  1:2,  1:5,  and  1:10,  also  a  device  whereby  the  pencil  movement  can  be 
changed  and  made  to  travel  over  the  drum  in  a  period  of  either  1  or  8  days. 
(See  Lietz  Duplex  Time  Water  Register  Nos.  362-363.)  Any  other  ratio, 
as  well  as  interchangeable  ratios,  can  also  be  supplied. 

The  cut  shows  the  latest  improvements,  which  consist  principally  of  a 
remodeled  pencil  carriage  and  a  water-tight  aluminum  clock  case;  the  entire 
apparatus  is  enclosed  with  a  galvanized  iron  cover  not  shown  in  the  cut. 

Write  for  folder  containing  Instructions  for  Installation,  also  abstract 
from  paper  published  in  Bulletin  of  American  Society  of  Civil  Engineers, 
November,  1910,  by  J.  C.  Stevens,  describing  results  obtained.

LIETZ   WATER   REGISTERS 

The  Lietz  Water  Registers  arc  so  constructed  that  the  pencil  is  released 
by  the  clock  and  drawn  across  the  drum  by  a  small  weight,  which  works 
in  unison  with  the  clockworks.  The  drum  is  controlled  by  the  float  which 
rests  on  the  surface  of  the  water.  This  type  of  construction  is  a  great 
advantage  over  the  old  style,  wherein  the  drum  is  revolved  by  the  clock- 
work, inasmuch  as  it  relieves  the  clockwork  of  the  extra  labor  of  turning 
the  drum,  thus  assuring  greater  accuracy  of  time  and  also,  in  case  of  an 
extraordinary  rise  or  fall  of  the  water  (greater  than  the  capacity  of  the 
record  sheet),  the  Lietz  Water  Register  will  simply  make  two  or  more 
revolutions  and  the  record  can  easily  be  read,  while  on  the  old  type  of 
construction  any  rise  or  fall  over  the  capacity  of  the  Register  would  be 
lost. 

No.  360  Lietz  Improved  Water  Register  with  12-inch  drum,  high- 
grade  8-day  clock  movement,  complete  with  float,  weights

in  turn  is  wound  tightly  through  the 

fall  of  its  counterweight.     The  paper  is 

guided  over  the  cylinder  by  means  of 

small  projecting  pins  or  burs  attached 

to  its  ends  peripherally,  which  cause  a 

perforation  of  the  paper  at  intervals  of 

one  inch,  equal  to  two  hours  of  record. 

The  scale  on  which  the  curve  is  drawn 

is   such   that   one   inch   on   the   paper 

equals  one  foot  in  tidal  height. 

The  Reference  Pencil  "I,"  which  may  be  shifted  along  its  carriage,  is  a 

convenience  in  the  establishment  of  either  a  mean  or  initial  reading,  which 

readily  aids  in  the  taking  of  observations. 

The  gauge,  once  installed  and  in  working  order,  need  not  be  visited  more 
than  once  in  seven  days  for  the  purpose  of  winding  the  driving  clock  and

HENSOLDT  IMPROVED  PRISM  BINOCULARS 


Construction. 


No.  375 

Aluminum  Frames,  covered  in  black  morocco*  leather.  Jointed  cross 
bars  for  adjustment  of  pupillary  distances.  Universal  focusing  arrangement, 
and  one  turning  eye-piece,  graduated  plus  and  minus,  for  unequal  strength 
of  eyes.     Binoculars  contained  in  genuine  leather  case  with  sling  strap. 

The  novel  combined  prism  of  the  Hensoldt  Binocular  as  shown  in  the- 
above  illustration  allows  the  employment  of  object  glasses  of  larger  aperture 
(up  to  2  inches),  thereby  giving  a  higher  degree  of  brightness  than  other 
glasses.  It  also  permits  the  reduction  of  the  Aluminum  Frame  to  the 
slender  shape  of  a  telescope,  as  well  as  securing  the  optical  elements  more 
rigidly  in  proper  relation  to  each  other. 


This  illustration  shows  the  easy  access  to  internal  optical  parts  for  cleaning. 
*On  special  order  Hensoldt  Prism  Binoculars  can  be  furnished  in  tan  leather.

RAY  FILTER 


Hensoldt  Prismatic  Binoculars  and  Monoculars  are  often  furnished  with  an  extra  amber

adjusted  by  a  little  catch  on  the  side  of  each  barrel  and  the  glass  can  be  used  with  or  without 
the  Ray  Filter.

tions, enable  us  to  present  all  the  better  brands  of  merchandise 
offered  by  houses  specializing  in  their  respective  lines,  and  it  will 
always  be  our  endeavor  to  handle  only  the  best  articles  produced 
for  any  particular  purpose. 

We  hope  our  friends  will  keep  the  significance  of  these  remarks

LEVELING  RODS 

The  Leveling  Rods,  Nos.  410-425,  listed  on  page  181,  are  of  our 
own  manufacture,  graduated  to  hundredths,  by  uniform,  clean  divi- 
sions. The  black  numerals,  corresponding  to  the  tenths,  have  an 
exact  height  of  0.06  foot  and  the  red  or  foot  numerals  are  0.08  foot 
high.  This  affords  a  rod  reading  at  distances  where  graduation  lines 
disappear.  The  wood  is  the  best,  thoroughly  seasoned.  The  target 
and  all  connecting  metal  parts  are  cast  in  one  piece;  the  vernier 
made  to  read  to  thousandths ;  the  scale  is  brass,  face  of  target 
japanned.  We  recommend  these  rods  to  be  the  best  in  the  market. 
Made  in  two  self-reading  designs,  known  as  the  block  and  line 
graduations,  similar  to  the  Philadelphia  pattern. 

We  also  manufacture  a  complete  line  of  Flexible  Leveling  Rods 
and  Stadia  Rods  as  listed  on  the  following  pages.

ROD  LEVEL 

No.  449  Lietz  Improved  Rod  Level $3.00 

This  Rod  Level  is  an  improved  type,  used  to  hold 
rod  or  pole  of  any  shape  perpendicular.  The  level 
bubbles  are  sunk  in  the  casting  at  right  angles  to 
each  other,  thereby  lessening  the  possibility  of  break- 
age, as  well  as  making  it  easier  for  the  rodman  to 
hold  the  bubbles  in  the  center  than  the  old  form  of 
circular  spirit  levels.  The  latter  are  continually  leak- 
ing and  it  is  impossible  to  keep  them  in  order. 

The  Improved  Rod  Level  can  either  be  fastened 
to  the  rod  by  means  of  a  flat-head  screw,  for  which 
there  is  a  key  slot  provided,  or  pressed  against  the 
rod  or  pole  while  holding.  Indispensable  for  stadia 
work.

ai 


ZM 


This  tape  is  designed  to  answer  the  requirements  of  the  most  severe  usage,  and  to  take 
the  place  of  the  old-time,  yet  indestructible,  steel  chain.  It  is  made  of  practically  unbreakable 
steel,  somewhat  heavier  than  the  ordinary  chain  tape. 

Graduations  are  stamped  into  Babbitt  Metal  at  each  foot,  end  feet  in  tenths;  or  at  each 
link,  end  links  in  lOths  of  links.  Each  tape  is  provided  with  a  pair  of  detachable  handles,  or 
rawhide  thongs,  as  desired. 

Special  attention  is  called  to  this  reel,  which  is  built  especially  for  Babbitt  Metal  tapes. 
Nickel-plated  metal  frame,  with  folding  winding  handle.  A  very  serviceable  reel,  easily  wound 
and  of  beautiful  finish.

SHOULDERS  FOR  CHAIN  TAPES 


Some  surveyors  use  in  chaining  a  tape  equipped  with  shoulders.  These  shoulders  assist 
in  locating  the  zero  and  the  last  graduation.  They  are  carefully  soldered  to  the  tape  and 
when  so  ordered  will  be  supplied  on  any  of  our  chain  tapes.

Aluminum  frame  14  inches  long;  nickel-plated  steel  reel 
8  inches  in  diameter.  A  hardwood  roller  or  spool  is  fitted 
between  the  sides  or  discs  of  reel  which  by  means  of  a  spring 
presses  toward  the  axis  of  reel,  causing  the  tape  to  wind  up 
evenly  and  tightly  and  keeping  it  in  place.  Long,  neat  and 
strong  aluminum  winding  handle  with  large  metal  finger  hold, 
giving  a  winding  leverage  of  nearly  five  inches,  and  enabling 
the  winding  of  a  long  tape  with  exceptional  ease  and  rapidity. 
A  leather  strap  for  carrying  is  attached  to  one  end  of  the

SAN  FRANCISCO,  U.  S.  A. 

POCKET   MEASURING  TAPES 

LUFKIN  STEEL  TAPES 
Standard  of  Measurements 

Lufkin  Steel  Tapes  are  so  carefully  graduated  by  Standards  supplied  by 
the  United  States  Government  that  they  can  be  used  for  testing  the 
accuracy   of  other  tapes. 

Tension: 

Lufkin  Steel  Tapes  are  made  under  a  tension  of  10  pounds  for  tapes  up 
to  100  feet  in  length  and  20  pounds  if  longer.  They  are  accurate  when 
supported  full  length  at  this  tension. 

Temperature: 

Steel  tapes  graduated  in  customary  English  units  (feet,  inches,  etc.)  are 
standard  at  a  temperature  of  62°  Fahrenheit.  The  National  Bureau  of 
Standards  recommend  tapes  graduated  in  the  Metric  System  be  made 
Standard  at  20°  Centigrade,  this  being  the  normal  temperature  under  which 
they  are  used.  We  are  prepared  to  make  them  at  20°  Centigrade  if  so 
desired,  but  unless  otherwise  specified,  we  will  make  them  accurate  at 
0°  Centigrade,  which  is  the  customary  Standard  for  Countries  that  have 
adopted  the  Metric  System. 

CERTIFICATE  OF  COMPARISON 

OF   THE   NATIONAL   BUREAU    OF    STANDARDS 

AT  WASHINGTON,  D.  C. 

We  can  furnish  a  certificate  of  comparison  of  the  National  Bureau  of 
Standards  for  any  Lufkin  Steel  Tape  the  graduations  of  which  are  marked 
directly  on  the  steel  and  the  zero  of  the  graduations  is  represented  by  a 
line  marked  on  the  tape.  The  fees  of  the  Bureau  of  Standards  for  com- 
parisons are  given  below,  to  this  must  be  added  the  transportation  charges 
to  and  from  Washington,  D.  C. 
(A)      For  total  length,  not  greater  than  100  feet  or  50  meters,  either 

supported  throughout  or  at  intervals $0.75 

For  each  additional  100-foot  or  50-meter  interval .50 

(D)      For  comparing  total  length  both  supported  throughout  and  at 

intervals  for  length  of  100  feet  or  50  meters 1.25  , 

For  each  additional  100  feet  or  50  meters 1.00 

(F)  For  each  sub-division  compared .10 

(G)  For  determination  of  length  at  an  additional  tension,  for  each 

100- foot  or  50-meter  interval .25 

(H)  For  determining  the  tension  to  the  nearest  0.5  pound  or  0.25 
kilogram  at  which  the  tape  is  most  nearly  correct  at  the 
standard  temperature,  for  each  100-foot  or  50-meter  interval  .50 

For  tapes  not  sent  on  a  reel  there  will  be  an  additional  charge 

for  each  100-foot  or  50-meter  length  or  fraction  thereof  of  .25 

The  Bureau  of  Standards  certificate  states  the  temperature  at  which  the  comparison  was 
made,  the  method  of  support,  the  tension  used  in  making  comparison,  and  the  length  corrected 
for  the  standard  temperature.    The  number  of  each  certificate  is  also  etched  on  the  tape. 

INSTANTANEOUS   READINGS 


Instantaneous  Readings,  a  patented  system  of  marking  steel  and  metallic  tapes,  consists 
of  repeating  the  foot  marks  at  every  inch  in  small,  yet  easily  distinguishable  figures.  Thus  the 
total  reading  is  brought  directly  before  the  eye,  eliminating  all  chance  of  possible  error,  and 
saving  valuable  time.

The  frames  of  these  tapes  are  fitted  with  a  folding  lock  handle,  which 
folds  over  the  tape,  enabling  one  to  stop  it  at  any  desired  length.  This 
handle,  on  account  of  its  length,  also  affords  increased  winding  leverage, 
which,  together  with  the  large  knob,  makes  it  especially  convenient  and

DUPLICATING  FIELD  BOOKS 

The  Duplicating  Field  Book  fills  a  long  felt  want  of  civil  and  mining  engineers  where  field 
parties  are  more  or  less  distant  from  the  office  where  the  plotting  is  done.  By  making  a  single 
entry  it  enables  the  engineering  corps  in  the  field  to  furnish  the  home  office  with  a  duplicate

Loose  Leaf  Field  Books  are  advantageous  to  engineers  in  many  respects.  They  enable  one 
to  leave  finished  notes  in  the  drafting  room  while  the  books  are  still  being  used  in  the  field 
and  to  remove  certain  leaves  if  necessary.  We  offer  the  profession  the  following  assortment. 
Our  Field  Binders  Nos.  790  and  792  are  made  of  extra  heavy  leather  covered  material  and  are 
very  durable.  The  mechanism  is  strong  and  consists  of  six  metal  rings  which  are  readily 
opened  when  necessary.  The  Office  Binder  No.  791  is  made  of  strong  cloth  covered  material 
with  similar  mechanism.  It  is  intended  for  use  in  the  office  and  for  filing  sheets.  This  binder 
can  also  be  used  in  the  field  and  has  proven  very  satisfactory  for  this  purpose.  The  leaves  are 
ruled  on  extra  heavy  stock  and  are  similar  in  design  and  colors  to  our  regular  field  books.

LOGARITHMIC  PAPER 


Logarithmic  Paper  is  so  ruled  that  the  scales  in  each  direction  are  logarithmic  instead  of 
uniform,  as  on  other  cross-section  papers;  the  numbers  and  divisions  marked  are  placed  at  such 
points  as  to  make  their  distances  from  the  origin  proportional  to  the  logarithm  of  such  numbers 
instead  of  to  the  numbers  themselves.  By  means  of  this  paper  logarithmic  operations  are  per- 
formed graphically,  without  reference  to  the  logarithms  themselves.  Many  hydraulic  and  other 
engineering  computations  are  facilitated  by  its  use,  and  various  relationships  (sizes  of  tie-bars, 
shafts,  etc.,  in  terms  of  varying  load,  or  the  inverse;  circumferences  and  diameters  of  circles  in 
terms  of  their  radii  or  diameters,  or  the  inverse;  weights  of  the  series  of  bodies  of  the  same 
substance  and  form,  but  of  varying  size,  or. the  inverse,  etc.,  etc.),  can  be  represented.

The  constantly  increasing  demand  of  the  larger  drawing  rooms  for  standard  sizes  of 
tracing  cloth  and  tracing  paper  sheets  has  induced  us  to  cater  to  this  requirement.  We  have 
executed  any  number  of  intricate  jobs  and  our  experiences  are  offered  the  profession  with  the 
assurance  that  highly  satisfactory  results  will  be  had  if  this  work  is  entrusted  to  us.  Special 
non-smearing  and  absolutely  opaque  ink  used. 

We  call  attention  to  the  illustration  above.  Note  that  the  printed  headings  are  absolutely 
in  line  with  the  horizontal  rulings,  also  that  the  lines  are  unbroken  and  joined  perfectly,  an 
accomplishment  unattainable  unless  executed  in  our  special  manner.  Sheets  printed  on  the 
under  or  reverse  side,  if  desired,  to  allow  for  thorough  erasing  or  cleaning  without  danger  of 
destroying  the  printed  matter.

VACUUM  BLUE  PRINT  FRAMES 


No.  1275 

For  obtaining  the  closest  contact  these  frames  are  unsurpassed.  By 
means  of  a  pump  the  air  is  entirely  exhausted  from  between  the  cushion  and 
the  glass,  forming  the  best  contact  obtainable  between  the  tracing  and 
sensitized  paper. 

By  use  of  the  vacuum  frame  the  faintest  lines  of  a  drawing  can  be  repro- 
duced, or  drawings  wrinkled  or  worn  by  much  handling  can  be  flattened 
out  and  good  prints  taken  therefrom. 

This  frame  is  particularly  well  adapted  for  making  negative  and  blue 
line  prints.

THE  NEW  BUCKEYE  ELECTRIC  BLUE  PRINT 
MACHINE 


No. 
No 
No 


Of  the  various  types  of  cylin- 
drical Blue  Print  Machines  which 
have  been  offered  we  are  convinced 
that  the  NEW  BUCKEYE  is  the 
most  practical  from  the  standpoint 
of  operation,  the  most  economical 
from  a  viewpoint  of  operation  cost 
and  the  most  satisfactory  from  re- 
sults  obtainable. 

An  advantage  of  this  machine  is 
that  it  can  be  purchased  with  but  one 
half-cylinder  glass ;  the  other,  to 
complete  the  machine,  may  be  added 
later.  This  is  an  advantage  where 
the  first  cost  is  a  consideration. 

The  half-cylinders  are  each  pro- 
vided with  a  curtain  to  hold  trac- 
ings and  paper  tightly  against  the 
glass  during  exposure,  perfect  con- 
tact being  assured.  Tension  on  the 
curtains  is  maintained  by  means  of 
weights  attached  to  small  wire  cables 
which  engage  both  ends  of  the 
rollers.  A  roller  being  used  on  each 
side  of  the  machine  makes  it  possible 
to.  operate  one  independent  of  the 
other,  thus  one  side  only  may  be 
used  or  one  side  may  be  unloaded  or 
reloaded  while  the  other  is  printing. 

LAMP — Especially  constructed  for 
blue  printing,  emitting  an  intense 
light,    rich    in    actinic  or   violet  rays. 

SPEED  GOVERNOR,  for  regu- 
lating the  length  of  exposure,  is  of 
the  rotary  type  in  an  oil-tight  case. 
The  weight  of  the  lamp  supplies  the 
power. 

SAFETY  STOP— A  device  to  pre- 
vent lamp  from  dropping  in  case 
supporting  cable   should  break. 

AUTOMATIC  CUT-OUT  —  Pro- 
vided to  make  it  unnecessary  for 
operator  to  continually  watch  ma- 
chine, the  current  being  automatically 
shut  off   when    lamp   reaches   bottom. 

When  ordering  ascertain  from 
your  electric  company  whether  cur- 
rent is  direct  or  alternating;  if  latter 
give  frequency  of  cycles.

THE  REVOLUTE  BLUE  PRINTING  MACHINES 

The  efficiency  of  the  Revolute  Blue  Printing  Machines  is  due  to  the  fact 
that  they  are  built  upon  the  right  principle,  the  principle  of  rolling 
(revolving)  contact. 

Rolling  contact  is  obtained  by  a  revolving  glass  cylinder  and  a  series  of 
endless  belts  which  move  in  the  same  direction  at  the  same  rate  of  speed 
and  have  perfect  contact. 

The  source  of  light  passes  through  the  glass  cylinder  and  hits  the  tracing 
and  paper  which  is  fed  between  the  cylinder  and  the  endless  belts  and 
carried  by  them  through  the  part  revolution  while  the  printing  is  being  done. 

Rolling  contact  insures  perfect  and  uniform  contact  between  the  tracing 
and  the  paper  at  all  times  which  is  essential  in  making  prints  perfect  in 
detail  and  tone,  and  absolutely  eliminates  all  tendency  of  the  paper  to  slip 
on  the  tracing. 

The  Revolute  Blue  Printing  Machines  will  produce  blue  prints  at  the 
rate  of  two  to  twenty  linear  feet  per  minute,  depending  upon  the  quality  of 
the  paper  and  the  tracing.  The  cost  of  operation  per  unit  of  output  is 
extremely  low  and  they  are  very  economical  to  maintain  and  always  ready 
for  instant  use,  self-contained  and  compact. 

They  will  make  a  perfect  reproduction  of  every  tracing  or  negative 
regardless  of  its  fineness  of  detail.  They  will  print  either  separately  cut 
sheets  or  continuous  rolls  from  either  cloth  or  paper  tracings. 

They  are  devoid  of  complicated  mechanism  and  are  simply  constructed 
and  easily  operated. 

On  the  Revolute  Blue  Printing  Machines  you  will  find  every  attachment 
that  can  be  designed  to  aid  their  speed  and  efficiency.  They  are  provided 
with  variable  speed  gears  with  indicators  which  enables  the  operator  to  set 
the  machine  at  the  right  speed  for  every  variation  in  paper  and  tracings, 
insuring  all  prints  perfect  with  no  loss  of  time  and  material  for  tests.  They 
are  equipped  with  paper  holders  to  which  the  paper  may  be  attached  and 
from  which  it  will  automatically  feed  into  the  machine. 

The  very  fast  machines  are,  and  the  others  may  be,  equipped  with  an 
automatic  winding-up  device  which  will  rewind  the  paper  as  it  is  delivered 
printed  from  the  machine. 

All  machines  are  provided  with  automatic  strippers  which  insure  the 
paper  and  the  tracing  leaving  the  cylinder  at  the  proper  moment. 

If  interested  in  Washing,  Drying  and  Ironing  Machines  or  other  blue 
print  room   equipment  send  for   descriptive  circular.

PHOTO  PRINT  SERVICE 

Photostat  reproductions  of  every  description.  Maps,  blue  prints,  legal  papers,  financial 
statements,  manifests  and  all  written  or  printed  documents  can  be  quickly  and  economically 
copied  by  this  process  in  any  quantities.  Prices  vary  according  to  size  and  quantities  required 
and  are  cheerfully  quoted  on  application.     Samples  of  work  sent  on  request. 

LITHO  PRINT  PROCESS 

A  comparatively  recent  process  by  which  tracings,  either  pencil  or  ink,  can  be  printed 
upon  tracing  cloth,  linaura  cloth  or  papers  of  any  desired  thickness.  It  offers  unlimited  pos- 
sibles as  can  be  appreciated  from  the  fact  that  a  tracing  cloth  copy  can  be  made  from  a 
tracing,  and  from  which  in  turn  blue  prints  or  negatives  can  be  made  if  required.  Architects 
find  it  most  appropriate  for  duplicating  their  ink  or  pencil  tracings  upon  heavier  papers  since 
rendering  is  beautifully  effected  in  so  doing.  It  being  a  DRY  PROCESS  all  shrinkage  is 
overcome.  It  can  be  appreciated  that  this  is  important  in  certain  classes  of  work  since  the 
shrinkage  in  blue  printing  is  well  understood  and  under  the  negative  and  blue-line  processes 
is  doubled. 

Prices  vary  according  to  size  and  quantities,  but  compare  very  favorably  with  the  charges 
as  made  for  negative  and  blue-line  work,  and  we  therefore  urge  our  friends  to  a  consideration 
of  the  LITHO  PROCESS  when  requiring  copies  of  their  tracings.     Write  us  for  quotations. 

MOUNTING  SERVICE 

Patronage  solicited  for  map  mounting  in  all  forms,  continuous  rolls,  sheets,  cut  to  fold 
for  pocket  use,  etc.  We  have  facilities  for  mounting  extra  large  sheets,  joining  them  per- 
fectly, and  can  furnish  double  mounted  sheets  (muslin  between)  for  platbook  or  record  use. 
Inquiries  will  receive  prompt  attention.

DRAWING  INSTRUMENTS 

FACTS  TO  BE  CONSIDERED  IN  SELECTING 

Before  describing  the  qualities  of  the  various  grades  of  Drawing  Instru- 
ments about  to  be  presented,  we  feel  that  a  few  remarks  on  the  selection 
of  instruments  are  not  amiss.  This  for  the  guidance  of  our  friends  residing 
away  from  the  larger  cities  (where  examination  of  the  goods  is  impossible) 
and  for  the  layman  or  student,  inexperienced  in  the  use  of  Drawing 
Instruments. 

We  hope,  by  this,  to. create  a  better  understanding  as  to  the  different 
classes  of  instruments  and  their  respective  qualities  and  the  purposes  for 
which  each  line  is  primarily  intended. 

The  varieties  and  qualities  of  Drawing  Instruments  are  now  so  numerous 
and  the  finish,  in  all,  so  very  similar  (even  though  the  intrinsic  values  are 
far  greater  in  one  than  in  another),  that  we  have  found  it  difficult  for  most 
anyone  to  grasp  the  actual  and  the  comparative  values  of  an  instrument. 

The  quality  can  be  determined  only  by  their  efficiency  and  durability 
in  actual  use  and  for  this  reason  the  advice  of  an  instructor  of  drawing  or 
that  of  an  experienced  draftsman  is  often  sought  by  the  beginner  when 
considering  the  purchase  of  drawing  tools. 

Few  people,  however,  have  the  good  fortune  to  be  thus  guided  and  are 
compelled  to  rely  solely  upon  the  reputation  of  the  dealer.  We  solicit 
consultation,  either  by  personal  visit  or  through  correspondence,  giving  the 
assurance  to  our  patrons  of  an  honest  representation  of  the  merits  of  the 
goods  under  consideration.  The  A.  Lietz  Co.,  with  its  long  established 
business  career  and  reputation  for  honest  dealings,  will  positively  insure 
against  misrepresentation. 

The  life  and  the  efficiency  of  Drawing  Instruments  depends  entirely 
upon  the  qualities  of  the  materials  or  metals  employed  in  their  manufacture 
and  not  on  the  finish;  upon  careful  and  conscientious  workmanship  and  on 
their  design  and  general  form. 

Drawing  Instruments  recognized  as  of  the  highest  quality  are  made  of 
finest  hard  rolled  German  silver  and  best  English  steel  and  are  not  cast  or 
coined  in  die.  The  employment  of  hard  rolled  plate  metal  naturally  adds 
to  the  cost  of  making  but  it  is  absolutely  necessary  in  the  production  of 
durable  instruments;  and  being  so  made,  they  will  outlast  the  actual  need  of 
professional  draftsmen;  in  fact,  have  been  known  to  be  in  use  through 
successive  generations. 

DESCRIPTION  OF  VARIOUS  QUALITIES 
Atee-  SUPERIOR  KERN   SWISS  DRAWING  INSTRUMENTS 

By  reason  of  the  great  care  in  the  selection  of  the  materials  and  the 
attention  given  to  the  perfection  in  all  the  details  of  their  manufacture, 
Kern  Swiss  Drawing  Instruments  have  during  the  last  century  become 
recognized  as  the  world's  standard  and  highest  quality.

INSTRUMENTS 

Each  instrument  stamped  with  trade  mark. 


The  Kern  Patent  Pivot  Joint  Head  offers  the  great  advantage  over  all 
other  types  of  construction  in  that  it  entirely  suppresses  any  lost  motion  or 
injurious  friction  and  that  the  stability  of  the  head  of  the  compass  is  greatly 
increased.  We  carry  all  Kern  Dividers  and  Compasses  with  straightening 
device  which  admits  of  maintaining  the  handle  in  a  perpendicular  position  at 
all  times. 


Original  Pattern  Compasses  have  the  one  leg  made  in 
one  length.  The  needle  is  kept  in  a  sheath  and  clamped  by 
a  set  screw  between  the  split  end  of  that  leg.  Thus  the 
needle  may  be  put  in  any  desired  angle  to  it,  i.  e.,  perpen- 
dicular to  the  paper,  permitting  use  of  the  entire  length  of 
leg  and  giving  the  compasses  the  widest  possible  range. 

The  other  leg  taking  the  points  is  jointed  instead  of  the 
needle  pencil  or  pen  pieces  having  their  joint. 

The  points  are  fastened  in  a  very  solid  way  and  the 
needle  in  its  holder  or  sheath  is  as  steady  as  if  in  one  piece 
with  the  leg.

THE  RAPID  DOT  AND  DASH  DEVICE 


The  Rapid  Dot  and  Dash  Device  as  applied  to  amber  triangles  or  amber- 
lined  T  squares  and  straight  edges  is  a  simple  and  most  practical  one,  con- 
sisting of  an  intermittent  groove  cut  just  in  back  of  the  edges. 

A  small  metal  attachment,  which  can  be  adjusted  to  either  nib  of  any 
ordinary  ruling  pen,  travels  along  these  grooves,  the  uncut  portions  causing 
the  pen  to  be  lifted  off  the  paper,  registering  the  spaces  between  the  dots 
and  dashes,  while  the  cut  portions  form  the  dots  and  dashes.  This  attach- 
ment, when  once  adjusted,  requires  no  changing  and  does  not  interfere  with 
the  use  of  the  pen  for  straight-line  work,  nor  do  the  grooves  in  any  way 
affect  the  edges  of  the  triangles  or  straightedges. 

We  recommend  this  device  as  the  most  perfect  and  efficient  dotting  in- 
strument yet  devised.  The  results  obtained  are  absolutely  perfect  and  the 
variety  of  designs  is  unlimited.  We  are  in  a  position  to  furnish  any  special 
design  to  order  and  offer  the  following  suggestions,  which  we  can  furnish 
on  a  day's  notice:

SURVEYORS'  INSTRUMENTS 


SAN  FRANCISCO,  U.  S.  A. 


ALCO  "CIRCLE  A"  DRAWING  INSTRUMENTS 

Each  instrument  stamped  ftLCO  ® 

The  one  point  of  great  importance  about  ALCO  "Circle  A"  Drawing 
Instruments  is  that  they  are  all  made  to  gauge,  all  parts  being  interchange- 
able. The  materials  used  are  very  finest  quality  of  rolled  German  silver  and 
best  steel.  . 

COMPASSES  AND  DIVIDERS 

The  foremost  requirement  in  Compasses  and  Dividers  intended  for  high- 
class  work  is  an  absolutely  true  and  steady  joint.  By  reason  of  their  con- 
struction the  joints  of  our  ALCO  "Circle  A"  Compasses  can  never  become 
loose  or  work  unevenly;  it  permits  of  exact  adjustment  and  may  readily  be 
oiled.  The  construction  is  shown  in  the  accompanying  illustrations.  Fig.  1 
shows  the  plain  joint  while  Fig.  2  illustrates  the  joint  in  connection  with  our 
straightening  device. 


Fig.  1 


Fig.  2 


Fig.  3 


The  shanks  of  the  Compasses  which  are  centrically  connected  by  a 
bipartite  pivot  showing  a  rounded  head  on  either  side,  are  enclosed  by  a 
fork  carrying  corresponding  cavities  on  either  side  of  its  inner  surface  to 
receive  the  rounded  heads  of  the  pivots.  The  ends  of  the  fork  are  drawn 
together  by  a  screw  passing  between  the  legs  of  the  compasses,  by  means  of 
which  the  tension  can  be  minutely  regulated. 

The  shanks  of  the  compasses  are  thus  held  together,  not  by  the  natural 
and  therefore  transient  elasticity  of  the  fork,  but  by  the  permanent  pressure 
exerted  by  the  screw.  This  construction  warrants  a  true  and  smooth  action 
at  all  times. 

The  straightening  device  forces  the  handle  to  remain  in  a  central  position 
to  the  legs.     The  construction  will  be  clear  by  reference  to  Fig.  3.

The  manner  by  which  pen.  pencil  and  needle  point  parts  are  held  in  place 
in  their  socket  is  very  simple,  but  at  the  same  time  effective,  so  that  these 
parts  can  never  net  shaky  (See  Fig.  41  The  socket  is  split  and  the  two  sides 
being  draw  together  by  a  T-bolt  screw  clamp  the  inserted  parts  firmly  in 
place. 


Fig.  4         Fig.  5 


All  Compasses  are  supplied  with  needle  point  parts;  these  when  inserted 
turn  the  instruments  into  perfect  Dividers.  One  of  the  legs  is  provided  with 
a  needle  point  held  in  a  split  reversible  sleeve  (Fig.  5),  so  that  either  a  plain 
or  shouldered  point  may  be  used.  The  points  can  always  be  adjusted  to  a 
position  perpendicular  to  the  paper  regardless  of  the  opening  and  without 
any  noticeable  shortening  of  the  leg,  in  this  way  avoiding  sliding  and  mis- 
placing of  the  center  point  and  allowing  the  instrument  to  be  used  on  a 
considerably  larger  radius  than  is  possible  with  the  old  style  Compasses, 
the  lengthening  bar  being  dispensable. 

All  needle  points  have  extremely  fine  and  sharp  points  allowing  of 
accurate  spacing  and  leaving  only  the  slightest  marks  on  the  paper.  They 
are  not  ordinary  sewing  needles  but  are  specially  made  for  the  instruments 
from  best  hardened  steel. 

In  all  of  the  ALCO  "Circle  A"  Drawing  Instruments  the  steel  points  are 
removable.  They  are  held  in  place  by  small  clamp  screws  and  can  be 
exchanged  very  easily  by  giving  the  heads  of  the  screws  half  a  turn  with 
the  screwdriver.  The  troublesome  regrinding  of  broken  points  is  entirely 
done  away  with.  If  a  point  is  worn  or  damaged  it  can  be  replaced  by  a 
new  one.    Reserve  points  are  supplied  with  every  set  of  instruments. 

The  Compasses  and  Dividers  are  of  the  flat-half-round  type.  Corners  and 
sharp  edges  are  avoided  as  much  as  possible  to  make  the  handling  more 
pleasant.  Screws  are  placed  between  the  legs  so  as  not  to  obstruct  the  view 
when  drawing.

ALCO  "CIRCLE  A"  DRAWING  INSTRUMENTS 

Each  instrument  stamped  ALCO  ® 

Another  great  advantage  of  the  ALCO  "Circle  A"  Drawing  Instruments 
is  the  interchangeableness  of  all  parts.  Not  only  pen  and  pencil  points  of 
one  pair  of  compasses  will  fit  exactly  into  any  other  of  the  same  size;  the 
legs  or  any  other  parts  of  one  instrument  fit  perfectly  into  any  other,  sizes, 
of  course,  being  equal. 

With  all  Compasses  ordered  in  cases  a  screwdriver  serving  as  leadbox 
and  a  metal  handle  is  furnished  whose  hollow  space  holds  several  reserve 
needle  points.  This  handle  serves  for  inserting  pen,  pencil  or  needle  point 
part,  so  that  each  of  them  may  be  used  as  a  separate  instrument. 

SPRING  BOW  INSTRUMENTS 

Are  made  in  two  distinctly  different  styles: 

Style  A.     Instruments  with  ANNULAR  spring,  Fig.  A  (new  style). 
Style  B.     Instruments  with  FLAT  spring,  Fig  B  (old  style). 
We  stock  only  the  style  A  instruments. 


Fig.  A 


Fig.  B 


Both  styles  are  fitted  either  with  side  or  center  screw  adjustment. 

Bow  instruments  of  the  annular  spring  construction  have  the  great  ad- 
vantage that  the  tension  of  the  shanks  remains  nearly  constant  for  any  spr'ead 
while  Bows  with  flat  springs  (old  style)  become  slacker  the  more  they  are 
opened.  The  shanks  are  made  of  German  silver  in  this  construction,  whereby 
rusting  is  avoided. 

The  threads  of  the  adjusting  screws  are  all  cut  very  deep  and  coarse, 
especially  those  of  the  center  adjustment  Bows,  to  insure  quick  motion  and 
to  avoid  the  disagreeable  stripping. 

All  Steel  Points  Are  Removable. 

All  Bows  have  instruments  comparatively  wide  spread,  especially  with 
the  4J4-in.  Bows,  so  a  good  deal  of  work  may  be  done  for  which  the  heavier 
Compasses  usually  are  too  clumsy.

Bow  Instrument  No.  1665  is  a  very  serviceable  complete  pocket  set  for 
small  work.  In  connection  with  the  metal  handle  it  contains  all  the  in- 
struments needed  by  a  draughtsman  for  this  kind  of  work. 


IMPROVED  ROTATING  BOW  PENS 


All  Rotating  Compasses  of  the  ordinary  type  have  the  disadvantage  that 
the  pen  or  pencil  points  move  in  an  arc  relative  to  the  center  point,  and 
since  a  pen  will  draw  properly  only  at  one  certain  position  to  the  paper,  it 
follows  that  the  angular  changes  occurring  in  the  position  of  the  pen  point 
will  necessarily  mar  the  performance  of  the  pen. 

In  Rotating  Compasses  Nos.  1668  and  1669  the  introduction  of  a  two- 
spring  arrangement  eliminates  this  defect  entirely,  it  forces  the  pen  point 
to  remain  parallel  to  the  center  point;  the  angle  to  the  drawing  surface  being 
constant  no  matter  what  the  size  of  the  circle  may  be. 

ALCO  "CIRCLE  A"  DRAWING  PENS 


The  Ruling  Pens  are  made  of  the  finest  quality  of  steel.  The  material 
used  in  Pens  Nos.  1600  to  1602  being  made  especially  hard,  they  are  un- 
equalled for  their  extreme  hardness  and  toughness. 

Lateral  motion  of  the  blades  is  entirely  overcome  in  the  pens  by  T-bolt 
screws.  The  screws  move  freely  and  can  adjust  themselves  to  the  position 
of  the  blades. 

All  Ruling  Pens  have  metal  handles.

ALCO  "CIRCLE  L"  DRAWING  INSTRUMENTS 

Each  instrument  stamped  ALCO    © 

Of  finest  hard  rolled  German  silver,  white  wrought  metal  and 
highest  grade  tool  steel. 


Features  of  the   Compasses. 


Embodying  improved  pivot  joint  construction,  head  true  and  nicely 
fitted.  Design  does  not  permit  of  looseness.  Patent  clamp  to  lock  instru- 
ment in  any  position.  Straightening  device  to  keep  handle  in  perpendicular 
position  at  all  times. 


Double  Steel  Knee  Joint 


Slip  Shank  Fitting 


These  features  prevent  looseness,  increasing  their  durability  to  a  very 
large  degree.  The  insertion  joints  are  nicely  fitted  and  very  strong,  making 
the  clamp  screw  almost  unnecessary. 


THE  PATENT  NEEDLE  ADJUSTMENT 

as  embodied  in  our  Alco  "Circle  L"  Compasses  and  Bow  Instru- 
ments offers  an  advantage  which  is  self-evident.  By  its  sim- 
plicity one  can  regulate  the  needle  to  a  nicety  and  very  much 
quicker  than  in -the  old  way. 

For   very   fine   work   this   feature    should   prove   invaluable, 
serving,  as  it  does,  the  duty  of  a  micrometer. 


THE  DIVIDER  POINTS 

are  so  made  that  they  are  readily  interchanged  or  replaced  by  simply  turn- 
ing the  clamp  screw,  overcoming  thereby  the  troublesome  regrinding  of  the 
broken  points.

ALCO  "CIRCLE  L"  DRAWING  INSTRUMENTS 
Each  instrument  stamped  ALCO   © 

The  Ruling  Pens  which  constitute  our  ALCO  "Circle  L"  line,  both  sep- 
arate and  in  sets,  arc  fitted  with  the  patent  Slide  Catch  feature.  We  firmly 
believe  that  of  all  the  devices  which  have  been  attempted  to  aid  the  drafts- 
man in  the  opening  and  cleaning  of  the  Ruling  Pen  this  idea  is  the  neatest, 
quickest  and  simplest  of  any  yet  devised. 


Open 


In  order  to  open  the  pen  (when  closed)  hold  firmly,  engaging  the  slide 
catch  with  thumb  and  in  this  manner  the  opening  and  closing  is  controlled; 
the  latter  by  bringing  pressure  to  bear  as  catch  is  slid  forward. 


■^aCSlJS 


BOW  INSTRUMENTS 


The  innovation  in  design  of  these  bow  instruments  lias  eliminated  the 
troublesome  stripping  of  the  threads.  Being  of  spring  construction  with 
inserted  left  and  right  threaded  nuts,  the  life  of  the  bow  is  indefinite.  The 
tension  remains  almost  constant  whereas  the  old  form,  due  to  unequal  wear 
or  strain,  are  soon  worn  out.  Please  note  that  the  threaded  ends  of  the 
center  wheel  never  project  beyond  the  side  of  the  bow.

This  Dotting  Instrument  is  very  prac- 
tical and  most  reliable. 

It  consists  of  a  German  silver  frame,

wheel,  holding  the  instrument  in  a  ver- 
tical   position  while   in  use.

which  a  ratchet  projects,  resting  on  the 
Dotting  Wheel  and  causing  the  pen  to 
rise  and  fall  according  to  the  notches 
in  the  Dotting  Wheel.  Care  should  be 
taken  to  adjust  the  ruling  pen  to  the 
right  position  before  using  the  instru- 
ment.

PLANIMETERS 

This  very  useful  instrument,  for  obtaining  areas,  is  so  well  known  to  the 
engineer  that  it  hardly  need  be  described  in  particular.  A  theoretical  discus- 
sion of  the  principles  underlying  its  operation  will  be  found  in  almost  any 
handbook  on  higher  surveying. 

We  submit  the  following  instructions  and  examples  for  using  these 
instruments: 

INSTRUCTIONS  FOR  USING  PLANIMETERS  ARRANGED  FOR 

MEASURING  AREAS  IN  SQUARE  INCHES  (OR  OTHER 

SINGLE  UNITS  ONLY) 


Planimeters  Nos.  2000  and  2001.    (Illustrated  on  page  372) 

With  needle  point  outside  the  diagram.  Put  the  instrument  on  the  draw- 
ing surface,  set  the  tracing  point  F  at  any  mark  on  the  outline  of  the  area, 
then  press  the  needle  point  E  slightly  into  the  paper  outside  the  curve,  and 
read  off  the  roller  D  and  the  counting  wheel  G,  taking  the  whole  circum- 
ference of  the  recording  roller  as  the  unit  of  the  reading  (the  roller  need  not 
be  set  to  zero). 

Readings.  The  drum  of  the  roller  is  divided  into  100  parts.  The  tenths 
of  a  part  are  read  on  the  vernier.  The  complete  turns  of  the  roller  are  read 
on  the  counting  disc,  which  advances  one  line  at  every  complete  turn.  The 
counting  disc  performs  one  revolution  at  every  10  turns  of  the  roller. 

Each  complete  reading  is  a  figure  of  4  digits,  the  units  being  read  on  the 
counting  disc,  the  tenths  and  hundredths  on  a  drum,  and  the  thousandths  on 
the  vernier. 

The  reading  of  the  roller  and  disc,  shown  for  example  in  the  adjoining 
figure,  is  5.343. 

(The  zero  of  the  drum  and  a  mark  of  the  disc  should  simultaneously  be 
opposite  the  fixed  index  mark.  This  is  never  exactly  the  case  in  consequence 
of  the  imperfection  of  the  worm  wheel  gear,  and  this  should  be  taken  into 
account  in  making  readings  in  the  same  way  as  with  a  watch,  when  the 
minute  hand  points  to  12,  while  the  hour  hand  fails  to  indicate  the  exact 
hour.) 

Then  move  the  tracing  point  F  around  the  area  in  the  direction  of  the 
movement  of  the  hands  of  a  watch  till  it  reaches  again  the  starting  point. 
Now  take  another  reading  and  subtract  the  first  from  the  second  reading. 
The  difference  multiplied  by  10  will  then  be  the  area  of  the  curve  in  square 
inches. 

Example:  To  measure  the  area  of  a  square  of  4-inch  sides. 

Result:   Second  reading         3.073 
first  reading        —  1.473

If  the  reading,  before  starting,  had  been  9.521  then  the  reading  after  circum- 
scribing the  same  square  as  before  would  be  1.121.  As  the  travel  of  the  roller  is  in 
both  cases  the  same,  it  is  evident  that  the  zero  mark  of  the  wheel  has  passed  the 
fixed  index  mark' and  that,  consequently,  the  second  reading  has  now  to  be  supplied 
with  one  more  digit  on  the  left  before  substracting  the  first  reading.  Thus 
Complete  second  reading  11.121 
first  reading        —     9.521 


1.600  X  10  =  16  sq.  ins. 

With  needle  point  inside  the  diagram.  Circumscribe  the  diagram  with 
the  tracing  point  in  the  direction  of  the  movement  of  the  hands  of  a  watch, 
watching  at  the  same  time  the  counter  in  order  to  see  whether  the  total 
rotation  of  the  roller  is  a  forward  or  a  back  motion. 

This  preliminary  rough  operation  being  completed  proceed  as  explained 
before,  following  the  curve  carefully  with  the  tracing  point.  If  the  total 
rotation  of  the  roller  has  been  a  forward  motion,  subtract  the  first  from  the 
second  reading  and  add  the  difference  to  the  figure  engraved  on  the  top  of 
the  small  weight  used  for  keeping  the  needle  point  in  its  place.  The  sum 
multiplied  by  10  will  then  be  the  area  of  the  curve  in  square  inches. 

Example:  To  measure  a  circle  of  18  inches  in  diameter.  (You  will  see 
that  the  total  rotation  of  the  roller  is  forward.) 

Result:    Second  reading        9.884 
first  reading       —  0.868

If  the  total  rotation  of  the  roller  is  a  back  motion,  subtract  the  second  from  the 
first  reading  and  subtract  the  difference  from  the  figure  on  the  weight. 

Example:     To  measure  a  square  of  11  inch  sides.  (You  will  see  that  the  total 
rotation  of  the  roller  is  backward.)

NOTE. — When  the  mark  o  on  the  roller  is  at  the  mark  o  on  the  vernier 
a  mark  of  the  counting  wheel  should  be  opposite  the  fixed  index  mark.  Any 
slight  noncoincidence  due  to  imperfection  of  worm  wheel  gear  may  readily 
be  allowed  for  in  taking  readings. 

The  area  corresponding  to  a  total  revolution  of  the  roller — 10  sq.  ins.  in 
the  above  example — is  engraved  on  the  weight  along  with  the  figure  before 
mentioned.

ac  =  acre,  mi  =  mile.) 

The  slide  being  set  on  the  bar,  place  the  instrument  upon  the  drawing 
and  measure  the  diagram  as  with  planimeter  No.  2000. 

Example:     To  measure  a  circle  of  5  inches  in  diameter  on  a  ]4"  plan. 

Set  the  index  mark  J  on  the  slide  to  the  division  200  □'  ^"  =  1',  press  the 
needle  point  E  outside  the  circle  into  the  paper,  set  the  tracing  point  F  to  any  mark 
of  the  circle,  read  off  the  counter  —  the  reading  may  be  1.322  —  follow  the  circle 
with  the  tracing  point  until  you  arrive  at  the  starting  point  and  read  again  the 
counter.    The  reading  will  then  become  2.893.

For  measuring  small  diagrams  drawn  on  the  J^"  or  l/i"  scale,  the  slide  may 

conveniently  be  set  to  the  last  division  on  the  bar  marked  .^r.  ::,  A,,  ~  , , 

If  the  needle  point  E  be  placed  inside  the  diagram  to  be  measured,  then  one  of 
the  figures  on  the  top  of  the  bar  must  be  used  in  the  same  way  as  the  figure  on  the 
weight  of  planimeter  No.  2000. 

Example :  To  measure  a  square  of  1 2-inch  sides  on  an  ordinance  map  (scale 
1  :  2500). 

Set  the  index  mark  on  the  back  of  the  slide  to  the  division  10  ac  1  :  2500. 

Suppose  that  the  counter  reads  2.482  before  starting  the  tracing  point. 

In  following  the  outline  of  the  square  you  will  see  that  the  total  rotation  of  the 
counter  is  backward  and  that  the  zero  mark  of  the  counting  wheel  passes  the  fixed

On  these  instruments  the  tracer  arm  is  graduated,  and  settings  can  very 
accurately  be  made  for  any  scale,  either  U.  S.  standard  or  foreign  measure- 
ment, and  allowances  can  be  made  for  any  shrinkage  of  the  paper.  The

below).  Range:  Circle  25  in.  in  diameter;  length  of  diagrams  2.8  in.  In 
neat  velvet-lined  case,   with   instructions.      Each    $30.00 

Arrangement  for  Finding  the  Mean  Height  of  Indicator  Diagrams 


This  arrange- 
ment consists  of 
]  two  steel  points 
(protected  by  metal 
caps  when  not  in 
use)  as  shown  in 
the  adjoining  illus- 
tration, one  at- 
tached to  the  top 
of  the  tracer  arm, 
the  other  to  the 
top  of  the  carriage. 


To  obtain  the  mean  height  of  the  diagram,  hold  the  instrument  upside  down,  and  by 
shifting  the  slide  on  the  bar,  adjust  the  two  steel  points  so  that  they  coincide  exactly  with  the 
length  of  the  diagram.  Then  place  the  planimeter  without  altering  the  relative  position  of 
slide  and  bar  in  the  usual  way  upon  the  drawing — needle  point  outside  the  diagram — and 
follow  the  outline  of  the  diagram  with  the  tracing  point.  The  difference  of  the  readings  at  the 
beginning  and  at  the  end  of  the  operation  divided  by  0.4  will  be  the  mean  height  of  the 
diagram,  expressed  in  inches. 


Example:     Second  reading 
first  reading

0.4)  0.448  =  1.12  ins.  =  mean  height. 

If  the  diagrams  for  up  and  down  stroke  are  measured  jointly,  divide  by  0 . 8 
instead  of  0.4. 

Mean  pressure  =  Mean  height  X  Scale  of  spring  of  indicator.  Supposing  the 
scale  of  the  spring  in  the  above  example  is  1 "  =  80  lbs.  per  sq.  in.,  then 

0.448  X  80 

Mean  pressure  = =  89 . 6  lbs.  per  sq.  in. 

0.4 

The  number  of  pounds  per  inch  of  height  being  usually  a  multiple  of  4,  the  arithmetical 
work  is  thus  extremely  simple.

COMPENSATING  PLANIMETERS 

Compensating  Planimeters  Nos.  2020,  2021  and  2022  are  in  two  separate 
parts:  one  is  the  tracer  arm  with  measuring  and  recording  wheels,  the  other 
the  polar  arm,  having  the  pole  weight  at  one  end  and  a  steel  ball  at  the 
other,  which  forms  a  ball  joint  with  the  carriage.  The  ball  joint  cannot 
become  loose  or  shaky,  nor  is  it  liable  to  be  injured  when  adjusting  the 
tracer  arm  or  during  shipment,  as  each  part  is  stored  in  the  case  separately. 
This  construction  gives  the  tracer  arm  a  motion  of  180°  in  either  direction, 
therefore  the  range  of  these  instruments  is  much  greater  than  that  of  the 
ordinary  planimeters. 

The  pole  is  so  constructed  as  to  combine  the  advantages  of  the  pole  plate 
and  the  needle  point,  as  the  point  need  not  be  pressed  into  the  paper  and 
may  be  used  for  setting  the  roller  to  zero  without  touching  the  measuring 
roller. 

By  measuring  a  diagram  with  the  pole  on  the  right,  and  then  on  the  left 
side  of  the  tracer  arm,  and  taking  the  mean  of  the  readings  all  errors  of  the 
instrument  are  compensated.

THE  ADJUSTABLE  POLE  ARM 


No.  2022 


The  adjustable  pole  arm,  extending  to  about  13  inches,  bears  index  marks  for  the  different 
settings  furnished  with  the  instrument,  and  can  be  adjusted  so  that  when  the  instrument  is 
used  with  the  pole  inside  of  a  figure,  the  constant  is  a  round  number,  20,000  for  any  setting. 
The  instrument  is  used  in  the  same  way  with  the  pole  inside  as  with  the  pole  outside,  and  by 
tracing  the  figure  with  the  pole  on  the  right  and  on  the  left  of  the  tracer  arm  (about  13  inches) 
and  taking  the  mean  of  the  readings,  large  areas  can  be  measured  with  great  accuracy.  The 
extensibility  of  the  pole  arm  and  the  great  range  of  the  tracer  arm  permit  of  measuring  very 
large  figures  with  the  pole  outside.  By  reducing  the  length  of  the  pole  and  tracer  arms,  the 
instrument  can  be  used  in  a  very  small  space.

arranged  for  measuring  areas  in  several  units  and  scales.  In  neat  velvet- 
lined  case,  with  instructions.      Each    $65.00 

Pantograph  Polar  Planimeter  is  particularly  well  adapted  for  measuring  very  large  or 
very  small  areas.  The  long  tracer  arm  has  a  range  of  a  circle  about  38"  in  diameter.  When 
using  the  long  tracer  arm  it  is  advisable  to  remove  the  tracing  point  of  the  short  arm,  and  the 
figure  is  traced  in  the  usual  manner.  The  short  tracer  arm  is  used  for  measuring  very  small 
areas.  The  tracing  point  is  set  on  the  figure,  and  the  tracing  point  of  the  LONGER  arm  is  so 
guided  that  the  tracing  point  of  the  shorter  arm  follows  the  outline.  As  the  two  tracing  points 
move  alike,  this  is  very  easily  manipulated.  When  using  the  short  tracing  arm  in  this  manner 
the  travel  of  the  measuring  wheel  for  the  area  is  increased,  in  consequence  of  which  the  value 
of  the  wheel  unit  is  smaller,  and  more  accurate  results  are  obtained. 


No.  2028 

No.  2028  Polar  Disc  Planimeter,  German  silver,  adjustable  tracer  arm  arranged  for 
measuring  areas  in  several  units  and  scales.  Range:  Area  enclosed  between 
two  concentric  circles  of  31  and  13  inches  in  diameter.     In  neat  Velvet-lined 

case.      Each    , $75.00 

The  Polar  Disc  Planimeter  is  especially  useful  when  figures  are  traced  on  paper  that  has 
been  folded,  rolled,  etc.,  as  the  measuring  wheel  revolves  on  a  plane  disc  instead  of  over  the 
paper  being  traced.  The  paper  on  the  disc  can  easily  be  renewed  at  any  time  by  removing  the 
screw  nut  on  top  of  the  disc.  More  accurate  results  are  thus  obtained  when  tracing  on  paper 
where  the  surface  has  in  any  manner  been  damaged.

IMPROVED  WILLIS  PLANIMETER 


No.  2035 

No.  2035  Improved  Willis   Planimeter,   in   neat  leather-covered   case 

l^x3Hx°^>  complete  with  instructions.    Each $25.00 

The  Improved  Willis  Planimeter  reads  M.  E.  P.  direct  from  indicator  diagram,  gives  areas 
of  regular  or  irregular  circles  or  diagrams  in  square  inches,  feet  and  yards  without  any  com- 
putation. 

The  usual  planimeter  has  a  recording  wheel  whose  axle  is  parallel  to  the  tracer  bar.  This 
wheel  scrapes  along  the  paper  for  all  movements  parallel  to  the  tracer  bar,  and  records  by 
rotating  all  movements  perpendicular  to  it.  The  instrument  to  which  we  call  attention  acts 
on  an  entirely  different  principle.  The  wheel  (W)  rolls  for  all  movements  parallel  to  the  tracer 
bar  and  its  steel  spindle  glides  beneath  roller  for  all  perpendicular  movements.  After  tracing 
a  figure  the  result  is  read  from  the  scale  next  to  the  wheel;  this  scale  being  triangular,  has  six 
graduated  edges,  any  one  of  which  can  be  brought  next  to  the  wheel,  thus  permitting  reading  to 
be  taken  in  the  unit  best  suited  to  the  work. 

The  recording  wheel  of  the  improved  Willis  Planimeter  is  made  of  steel  and  has  a  sharp 
edge,  which  takes  firm  hold  upon  the  paper  or  material  upon  which  the  instrument  is  operated, 
and  the  long  steel  shaft  of  this  wheel  glides  freely  beneath  the  rollers  (R)  and.  (S).  which 
practically  bear  the  weight  of  the  instrument,  and  makes  it  absolutely  frictionless.  This  con- 
struction gives  great  ease  of  movement,  and  the  instrument  is  handled  as  readily  on  a  rough 
table  as  on  the  finest  paper.  As  the  rotary  movement  is  not  registered,  it  is  apparent  that  the 
accuracy  of  the  instrument  is  not  affected  by  the  character  of  the  paper  or  material  upon  which 
the  instrument  is  operated,  or  by  any  slight  reduction  of  the  diameter  of  the  wheel  or  injury  to 
the  knife  edge.  This  is  one  of  the  most  important  points  to  be  considered  in  the  selection  of  a 
planimeter.

MECHANICAL  INTEGRATORS 

With  the  aid  of  these  instruments  it  is  possible  to  ascertain  the  area  and 
moments  relative  to  an  axis  of  any  figure,  by  simply  tracing  its  outline. 
They  greatly  facilitate  the  finding  of  the  displacement,  moments  of  stability 
and  inertia,  center  of  gravity,  etc.,  of  ships,  the  tensile  strength,  resistance. 
safe  load,  etc.,  of  tracks,  cables,  beams,  contents  of  embankments,  etc.  The 
readings  are  taken  from  the  recording  discs.  These  instruments  are  very 
simple,  and  can  be  used  by  anybody  after  a  little  practice.

to  the  center  of  rotation  of  the  instrument,  the  travel  of  the  measuring 
wheel  is  increased,  as  a  consequence  the  area  value  of  the  wheel  unit  is 
smaller,  and  more  accurate  results  are  obtained.  Very  large  figures  can  be 
measured  in  sections.  By  means  of  a  formula  furnished  with  each  instru- 
ment, area  and  moment  of  figures  drawn  to  scale  can  easily  be  obtained.

THE  MECHANICAL  INTEGRAPH 

The  Integraph  is  an  integrator  which  not  only  indicates  the  final  result 
of  the  integration,  but  also  gives  a  graphic  representation  thereof.  While 
the  tracer  travels  around  the  outline  of  the  figure,  the  integraph  automatically 
draws  an  integral  curve  the  ordinates  of  which  are  proportionate  to  the 
area  of  the  figure  traveled  around  (vi  =_/>'■  dx).  If  this  first  integral  curve 
is  traced  by  the  tracer  of  the  integraph  as  a  differential  curve,  the  tracer 
draws  a  second  integral  curve  the  ordinates  of  which  are  proportional  to  the 
moment  of  stability  (yj  =fy2  dx).  By  tracing  this  second  integral  curve  we 
obtain  a  third  integral  curve  the  ordinates  of  which  are  proportional  to  the 
moment  of  inertia  (ys  =/  y3  dx)  etc.  The  y-axis  for  the  moments  can  be 
chosen  anywhere  on  the  curve,  i.  e.,  it  can  be  shifted.  By  means  of  the 
integraph  many  of  the  most  difficult  calculations  and  problems  occurring  in 
the  practice  of  an  engineer  can  be  solved  in  a  simple  and  reliable  manner  and 
with  much  saving  of  time  and  the  operator  need  not  possess  any  knowledge 
of  higher  mathematics. 

The  applications  of  the  integraph  are  very  numerous.  With  it  we  calcu- 
late areas,  divide  areas,  determine  centers  of  gravity,  calculate  moments  of 
stability,  load  and  resistance,  solve  algebraical  equations,  etc.

THE  UNIVERSAL  DRAFTING  MACHINE 


Cut  shows  Mid-Anchor  Machine 


The  Universal  Drafting  Machine  consists  of  two  parallelograms,  a  protractor,  and  a 
square  having  graduated  ruling  edges.  The  blades  of  the  square  are  interchangeable  for  all 
graduations. 

The  two  parallelograms  joined  together  constitute  an  arm  which,  anchored  to  the  board, 
gives  the  protractor  and  square  a  parallel  motion  about  the  drawing.  This  form  of  parallel 
motion  permits  either  zero  on  the  ruling  edges  to  be  instantly  placed  at  any  point  on  the 
drawing,  by  a  single  direct  movement,  and  a  line  being  drawn  along  the  graduated  ruling 
edge,   just  the  exact  length  required. 

A  conveniently  arranged  protractor  permits  the  square  to  be  set  at  any  angle,  and  it  then 
has  the  same  parallel  motion  about  the  board  as  when  set  at  zero..  Machines  are  furnished 
with  either  of  the  three  following  protractors: 

STANDARD  PROTRACTOR.  Has  graduated  arc  allowing  square  to  be  set  at  any 
angle,  and  is  provided  with  automatic  stops  allowing  the  square  to  be  instantly  set  at  30°, 
45°,  60°    and   90°,  without  stopping  to  read  or  clamp  the  protractor. 

ARCHITECTURAL  AND  STRUCTURAL  PROTRACTOR.  Special  graduations  are 
added  to  this  protractor  giving  one-fifth,  one-fourth  and  one-third  roof  pitches  each  way 
from  zero,   also  special   graduations  to   give  two    inches  to  the  foot  each  way    from  zero. 

CIVIL  ENGINEERS*  PROTRACTOR.  This  protractor  has  two  independent  swinging 
motions,  the  same  as  on  a  transit.  The  protractor  is  graduated  to  one-half  degrees  and  the 
vernier  reads  to  minutes.  With  the  aid  of  this  protractor  it  is  a  simple  matter  to  duplicate 
work  (done  in  the  field)   on  the  drawing,  directly  from  the  field  notes. 

HARDENED  JOINT  AND  SOLID  ROD  DRAFTING  MACHINES 

The  Hardened  Joint  Solid  Rod  Drafting  Machine  is  a  development  from  the  original 
construction  of  the  Drafting  Machine.  Hardened,  ground  and  polished  straight  cylindrical 
pins  working  in  hardened,  ground  and  polished  bearings  form  the  bearings  of  this  machine, 
and  if  kept  properly  lubricated  and  free  from  dirt  they  will  give  many  years  of  good  service 
with   no   perceptible  wear. 

BALL  BEARING  TUBULAR  ROD  DRAFTING  MACHINES 

The  Ball  Bearing  Tubular  Rod  Drafting  Machine  is  an  achievement  that  makes  the 
Drafting  Machine  practically  ideal.  It  has  absolutely  no  play  in  the  bearings  and  is  fric- 
tionless.  It  is  light  in  weight  and  possesses  great  rigidity,  and  is  exceedingly  accurate,  and 
the  motion  is  smooth  and  light.

DRAFTSMEN'S  SCALES 

Ate*  Quality 


We  offer  two  types  of  scales:  the  Plain  Boxwood  and  the  White  Edge, 
the  latter  a  combination  of  boxwood  and  celluloid.  Both  are  made  of  the 
finest  materials  and  the  wood  is  thoroughly  seasoned.  They  are  engine 
divided  to  United  States  standard  measurements  and  the  graduations  are 
fine  and  clear  and  deeply  cut.  Both  the  Boxwood  and  the  White  Edge  Scales 
are  made  in  a  variety  of  shapes,  described  as  follows: 


Triangular  Scales,  Regular  Shape.  This  type  of  scale 
has  the  advantage  of  possessing  six  surfaces  and  affords  the 
greatest  range  of  scales. 

Triangular  Scales,  Improved  Shape.  Like  the  regular 
shape,  possess  six  surfaces  but  the  concaved  facet  shape 
affords  a  better  contact  with  the  drawing  and  allows  a 
better  angle  of  vision.  It  prevents  the  divisions  from 
wearing  off  by  friction. 

Flat  Scales,  Regular  Shape.  The  regular  shape  flat 
scales  have  two  bevels  for  graduations.  The  graduations 
are  more  conveniently  read  than  on  the  triangular  scales. 

Flat  Scales,  Double  Bevel.  These  scales  have  four  bevels 
for  graduations,  but  this  shape  necessitates  the  raising  of 
the  scale  to  bring  the  edge  in  close  contact  with  the  paper. 

Flat  Scales,  Opposite  Bevel.  This  type  of  scale  is  an 
improvement  on  the  regular  flat  scale  as  it  presents  but  one 
graduated  bevel  to  the  eye.    It  is  easily  picked  up  or  turned.

SCALES  MADE  TO  ORDER 

We  arc  equipped  to  furnish  special  scales  of  all  kinds,  and  in  order  to 
avoid  mistakes  or  delay  in  prolonged  corresponding  we  offer  the  following 
suggestions  when  ordering  special  scales: 

1 — State  whether  Boxwood  or  White  Edge  Scale  is  wanted. 
2 — State  shape  scale  is  to  be.    (See  page  400.) 
3 — State  length  of  scale  wanted. 

•1 — How  each  edge  is  to  be  .graduated.  State  whether  to  be  Open  Divided 
or  Full  Divided. 

There  are  two  distinctly  different  ways  of  graduating  a  scale:  the  Open 
Divided  and  the  Full  Divided  Scale. 

The  Open  Divided  Scales  are  generally  used  for  architectural  or  mechan- 
ical drawing  and  are  divided  in  inches  or  parts  of  inches,  which  represent 
feet  or  full  inches.  The  units  are  graduated  along  the  entire  length  and  the 
end  units  only  are  subdivided  to  inches  or  fractions. 

When  ordering  a  scale  divided  with  different  divisions,  two  to  each  edge, 
one  of  these  must  be  the  double  of  the  other,  as  for  instance,  $4x1,  \'/2x3  or 
'Ax'/i.  One  of  the  divisions  on  each  edge  is  then  numbered  from  the  right 
and  one  from  the  left.  On  an  open  divided  scale  with  -but  one  division  to 
each  edge  each  scale  is  ordinarily  numbered  reading  from  right  to  left  and 
from  left  to  right,  and  each  end  unit  is  subdivided  to  inches  or  fractions. 

We  can  furnish  the  above  scales,  fully  divided,  to  order  if  desired. 

The  Full  Divided  Scales,  or  Chain  Scales,  as  they  are  commonly  called, 
are  used  mostly  by  surveyors  or  civil  engineers.  They  are  generally  divided 
to  decimals  of  inches  or  feet,  and  subdivided  the  entire  length  of  the  scale. 
Therefore  it  is  possible  to  have  only  one  division  to  each  edge.  They  are 
usually  numbered  continuous  every  ten  divisions,  the  triangular  scales  read- 
ing from  left  to  right  and  the  flat  scales  reading  both  ways,  i.  e.,  from  left  to 
right  and  from  right  to  left. 

5 — State  how  each  edge  is  to  be  numbered,  from  left  to  right  or  right  to 
left  or  both  ways. 

It  is  advisable  when  ordering  special  scales  to  furnish  us  a  sketch.  This 
need  not  be  accurate.  All  that  is  necessary  is  to  show  the  divisions  as  you 
want  them,  the  length  of  the  various  graduation  marks,  and  the  numbering 
as  it  is  wanted.

THE  "INTERLOX"  SLIDE  RULE 


The  Interlox  Sliding  Rule  combines  a  rule  for  lineal  measurements  with  a  direct  reading 
inside  caliper  rule.  When  closed,  all  the  slides  are  locked  together  with  an  interlocking  device. 
The  first  slide,  when  pulled  out,  releases  the  second  slide,  the  second  releases  the  third,  and 
so  on.  This  interlocking  device  makes  it  impossible  to  make  any  error  in  taking  measurements 
as  the  slides  cannot  be  extended  or  closed  except  in  consecutive  order.  The  closing  is  effected 
by  pressing  a  key  spring  on  the  first  slide  which  releases  the  second,  the  second  the  third,  etc., 
until  closed. 

Illustration  shows  rule  in  position  for  taking  inside  measurements.  A  direct  reading  of 
the  distance  between  the  two  extreme  points  of  the  rule  is  obtained  where  indicated  by  arrow.

and  the  whole  liner  occupies  but  a  space  on  the  drawing  board  854  'n-  long. 
The  arm  is  perfectly  rigid.  An  extra  strong  steel  spring  clutches  the  car- 
riage firmly  at  any  point  along  the  bar,  so  that  there  is  positively  no  lost 
motion  in  any  of  its  parts,  although  the  pinching  together  of  either  left  or 
right  post  and  the  lever  forces  it  evenly  and  smoothly  forward  the  distance 
of  the  setting.  In  operating,  let  us  say  from  left  to  right,  bring  the  car,  by 
means  of  pressure,  to  the  left-hand  end  of  the  base.  Set  the  left  indicator  to 
the  desired  spacing,  clamp  firmly.  Place  the  forefinger  of  the  left  hand  on 
the  knurled  knob,  the  thumb  on  the  lever.  Press  together,  releasing  first  fore- 
finger, then  the  thumb.  In  reversing,  or  in  this  case,  operating  from  right 
to  left,  set  to  the  desired  spacing,  by  means  of  the  right-hand  indicator,  and 
proceed  as  before.

SLIDE  RULES 

The  Slide  Rule  is  an  indispensable  aid  to  anyone  who  in  his  business  is  called  upon  to  make  calcula- 
tions. The  principles  with  which  one  must  be  familiar  are  few  and  simple  and  are  easily  mastered  with 
little  practice. 

Abstract  from  Kent's  Mechanical  Engineers'  Pocket  Book,  9th  Edition,  1916. 

The  slide  rule  is  based  on  the  principles  that  the  addition  of  logarithms  multiplies  the  numbers  which 
they  represent,  and  subtracting  logarithms  divides  the  numbers.  By  its  use  the  operations  of  multiplica- 
tion, division,  the  finding  of  powers  and  the  extraction  of  roots,  may  be  performed  rapidly  and  with  an  ap- 
proximation to  accuracy  which  is  sufficient  for  many  purposes.  With  a  good  10-inch  Mannheim  rule  the 
results  obtained  are  usually  accurate  to  i  of  1  per  cent.  Much  greater  accuracy  is  obtained  with  cylin- 
drical rules  like  the  Thacher. 

The  rule  consists  of  a  fixed  and  a  sliding  part  both  of  which  are  ruled  with  logarithmic  scales;  that  is, 
with  consecutive  divisions  spaced  not  equally,  as  in  an  ordinary  scale,  but  in  proportion  to  the  logarithms 
of  a  series  of  numbers  from  1  to  10.  By  moving  the  slide  to  the  right  or  left  the  logarithms  are  added  or 
subtracted,  and  multiplication  or  division  of  the  numbers  thereby  effected.  The  scales  on  the  fixed  part 
of  the  rule  are  known  as  the  A  and  D  scales,  and  those  on  the  slide  as  the  B  and  C  scales.  A  and  B  are  the 
upper  and  C  and  D  are  the  lower  scales.  The  A  and  B  scales  are  each  divided  into  two,  left  hand  and  right 
hand,  each  being  a  reproduction,  one  half  the  size,  of  the  C  and  D  scales.  A  "runner,"  which  consists  of  a 
framed  glass  plate  with  a  fine  vertical  line  on  it,  iB  uBed  to  facilitate  some  of  the  operations.  The  numbering 
on  each  scale  begins  with  the  figure  1,  which  is  called  the  "index"  of  the  scale.  In  using  the  scale  the  figures 
1,  2,  3,  etc.,  are  to  be  taken  either  as  representing  these  numbers,  or  as  10,  20,  30,  etc.,  100,  200,  300,  etc., 
0.1,  0.2,  0.3,  etc.,  that  is,  the  numbers  multiplied  or  divided  by  10,  100,  etc.,  as  may  be  most  convenient 
for  the  solution  of  a  given  problem. 

The  following  examples  will  give  an  idea  of  the  method  of  using  the  slide  rule. 

Pro-portion. — Set  the  first  term  of  a  proportion  on  the  C  scale  opposite  the  second  term  on  the  D  Bcale, 
then  opposite  the  third  term  on  the  C  scale  read  the  fourth  term  on  the  D  scale. 

Example. — Find  the  fourth  term  in  the  proportion  12  :  21  ::  30  :  z.  Move  the  slide  to  the  right  until 
12  on  C  concides  with  21  on  D,  then  opposite  30  on  C  read  x  on  D ■=  52.5.  The  A  and  B  scales  may  be  used 
instead  of  C  and  D. 

Multiplication . — Set  the  index  or  figure  1  of  the  C  scale  to  one  of  the  factors  on  D. 

Example. — 25X3.  Move  the  slide  to  the  right  until  the  left  index  of  C  coincides  with  25  on  the  D 
scale.   Under  3  on  the  C  scale  will  be  found  the  product  on  the  D  scale,  =  75. 

Division. — Place  the  divisor  on  C  opposite  the  dividend  on  D,  and  the  quotient  will  be  found  on  D 
under  the  index  of  C. 

Example.— 750  -5-  25.  Move  the  slide  to  the  right  until  25  on  C  coincides  with  750  on  Z).  Under  the 
left  index  of  C  is  found  the  quotient  on  D,  =  30. 

Combined  Multiplication  and  Division. — Arrange  the  factors  to  be  multiplied  and  divided  in  the  form 
of  a  fraction  with  one  more  factor  in  the  numerator  than  in  the  denominator,  supplying  the  factor  1  if 
necessary.  Then  perform  alternate  division  and  multiplication,  using  the  runner  to  indicate  the  several 
partial  results. 

4X5X8 

Example. =8.9  nearly.   Set  3  on  C  over  4  on  D,  set  runner  to  5  on  C,  then  Bet  6  on  C  under 

3X6 
the  runner,  and  read  under  8  on  C  the  result  8.9  —  on  D. 

Involution  and  Evolution. — The  numbers  on  scales  A  and  B  are  the  squares  of  their  coinciding  numbers 
on  the  scales  C  and  D,  and  also  the  numbers  on  scales  C  and  D  are  the  square  roots  of  their  coinciding  num- 
bers on  scales  A  and  B . 

Example. — 4*=  16.    Set  the  runner  over  4  on  scale  D  and  read  16  on  A. 

y  16  =  4.  Set  the  runner  over  16  on  A  and  read  4  on  D. 

In  extracting  square  roots,  if  the  number  of  digits  is  odd,  take  the  number  on  the  left-hand  scale  of 
A',  if  the  number  of  digits  is  even,  take  the  number  on  the  right-hand  scale  of  A. 

To  cube  a  number,  perform  the  operations  of  squaring  and  multiplication. 

Example. — 2'=  8.   Set  the  index  of  C  over  2  on  D,  and  above  2  on  B  read  the  result  8  on  A. 

Extraction  of  the  Cube  Root. — Set  the  runner  over  the  number  on  A,  then  move  the  slide  until  there  is 
found  under  the  runner  on  B,  the  same  number  which  is  found  under  the  index  of  C  on  D;  this  number 
is  the  cube  root  desired. 

Example. — y8  =  2.  Set  the  runner  over  8  on  A,  move  the  slide  along  until  the  same  number 
appears  under  the  runner  on  B  and  under  the  index  of  Con  D;  this  will  be  the  number  2. 

Trigonometrical  Computations. — On  the  under  side  of  the  slide  (which  is  reversible)  are  placed  three 
scales,  a  scale  of  natural  sines  marked  S,  a  scale  of  natural  tangents  marked  T,  and  between  these  a  scale 
of  equal  parts.  To  use  these  scales,  reverse  the  slide,  bringing  its  under  side  to  the  top.  Coinciding  with 
an  angle  on  S  its  sine  will  be  found  on  A,  and  coinciding  with  an  angle  on  T  will  be  found  the  tangent  on 
D.    Sines  and  tangents  can  be  multiplied  or  divided  like  numbers.

THE  PRECISION  SLIDE  RULE 


The  Precision  Slide  Rules  are  similar  to  other  Mannheim  Slide  Rules,  but  the  results 
obtained  are  of  a  considerably  greater  accuracy.  The  increase  in  accuracy  is  obtained  by 
making  the  scale  length  of  the  logarithmic  unit  equal  to  50  cm.  instead  of  12.5  cm  or  25  cm. 
The  scale  is  not,  however,  made  in  one  length  of  50  cm.  but  in  two  lengths  of  25  cm.  each. 
All  the  other  scales,  including  those  on  the  back  of  the  slide,  are  based  on  the  scale  length 
of  50  cm.;  so  that  all  calculations  with  this  slide  rule  have  a  uniform  and  considerably  greater 
degree  of  accuracy  than   those  made  with  the  ordinary  slide  rule.

THE  ALCO  SLIDE  RULE 


This  Slide  Rule  differs  from  those  hitherto  ordinarily  employed  in  that  it 
has  on  its  front  face  not  only  the  four  middle  scales  (two  on  the  rule  A  and 
D;  and  two  on  the  slide  B  and  C),  but  also  two  other  scales,  viz.,  an  evenly 
divided  scale  E,  on  the  lower  margin,  and  a  logarithmic  scale  F,  at  the  top, 
the  latter  consisting  of  three  similar  scales,  placed  consecutively. 

By  this  arrangement,  logarithms,  cubes  and  cube  roots  can  be  directly 
and  easily  determined.  With  the  ordinary  slide  rules  these  calculations, 
especially  the  extraction  of  cube  roots,  are  somewhat  complicated,  and 
necessitate  the  use  of  the  slide. 

All  calculations  such  as  multiplication,  division,  involution,  evolution,  etc., 
are  carried  out  with  the  first  mentioned  scales,  A,  B,  C,  D.

The  Hazen-Williams  Hydraulic  Slide  Rule  is  used  principally  for  deter- 
mining the  velocity  and  quantity  of  the  flow  of  water  in  pipes  and  channels, 
but  is  also  adapted  for  ordinary  slide  rule  calculations.  Special  computations 
may  also  be  solved  by  its  use,  as,  for  instance,  to  determine  the  corresponding 
flow  at  any  other  slope  or  head,  when  the  flow  of  water  through  a  pipe  or 
"system  of  pipes  produced  by  a  given  slope  or  head  is  known;  to  find  what 
size  of  pipe  must  be  used  to  produce  the  same  discharge  for  any  other  slope, 
when  the  discharge  in  a  given  size  of  pipe  at  a  given  slope  is  known;  to  com- 
pute the  discharge  through  a  compound  pipe,  that  is,  a  pipe  of  larger  diameter 
connecting  with  a  pipe  of  smaller  diameter,  or  a  series  of  such  pipes;  to 
compute  the  friction  of  a  given  amount  of  water  flowing  through  two  pipes 
of  different  diameters  and  different  lengths,  freely  connected  at  each  end;  to 
get  with  one  setting  of  the  slide  the  quantity  of  water  corresponding  to  any 
slope;  to  get  with  one  setting  of  the  slide  the  quantities  of  water  discharged 
by  pipes  of  different  sizes  for  a  given  slope  and  coefficient.  In  size  and  gen-

THE  IMPROVED  HALDEN  CALCULEX 

2Y&  inches  diameter  by  %  inch  thick. 

This  is  a  very  compact,  convenient  and  accurate 
instrument  and  very  simple  to  operate.  It  is  made 
entirely  of  metal  and  its  construction  is  extremely 
simple,  so  that  it  is  impossible  for  the  instrument 
to  get  out  of  order. 

The  book  of  rules  accompanying  each  instru- 
ment is  most  extensive  and  complete,  yet  very  clear 
and  easy  to  understand.  It  has  been  arranged  so 
as  to  fit  in  a  separate  compartment  of  the  leather 
case  containing  the  instrument,  so  that  both  to- 
gether can  be  conveniently  carried  in  the  vest 
pocket. 

The  Calculex,  briefly  described,  consists  of  a 
disc  within  a  fixed  ring,  which  together  form  a  dial 
with  logarithmic  scales  on  both  sides,  surrounded 
by  a  metal  ring  and  protected  on  both  sides  by  a 
glass  rim  with  an  indicator  hair  line  marked  there- 
on. 

The  instrument  is  operated  by  turning  the  disc, 
holding  the  nut  on  either  side  between  finger  and 
thumb.     The  outside  ring  is  fastened  to  the  rim. 

Logs  of   numbers,    squares,    square   roots,  cubes, 
cube  roots,  angles,  can  be  read  direct  from  the  in- 
dicator line,  without  turning  the  disc. 
No.  3075  T°e    ^ont    face    contains    five    circles   of    scales. 

The  outer  scale  No.    1  is  a  scale  of  Logs;  Nos.  2 
and   3   are  the  calculating  scales  A  and    B,   Nos.    4 
and  5  are  the  square  roots  of  B  scale, 
The  reverse  contains  six  circles  of  scales.     The  outer  scale,   No.   6,  is  a  scale  of  angles, 
Nos.   7  and  S  are  calculating  scales  for  reverse  proportions,  Nos.  9,  10  and   11  are  cube  roots 
of  scale  B.

The  Merritt  Beam  Scale  for  computing  the  strength  of  steel  beams  is  based  on  the  prin- 
ciple of  the  Engineer's  Slide  Rule  and  was  designed  to  simplify  computations  of  this  kind, 
and  to  eliminate  all  chance  of  errors.  Tables  and  formulae  are  absolutely  unnecessary  when 
the  Merritt  Beam  Scale  is  used,  and  the  speed  with  which  answers  to  widely  varying  prob- 
lems may  be  solved  can  hardly  be  appreciated  by  anyone  who  has  not  had  the  pleasure  of 
using  it.

To  illustrate  the  simplicity  of  the  Scale  the  following  is  given: 

How  far  apart  shall  6  in.  x  12  in.  timbers  of  white  oak  be  placed  to  safely  support  a  load 
of  150  pounds  per  square  foot,  the  span  being  18  feet,  and  New  York  law  governing  the  design? 

Select  the  fibre  stress  for  white  oak  allowed  in  New  York  City  (given  on  back  of  scale: 
1000  pounds).  Place  12  in  scale  B  below  6  in  scale  A.  Place  1000  in  scale  E  over  ISO  in

Thacher's  Calculating  Instrument  is  a  device  for  performing  a  great  variety  of  useful 
arithmetical  calculations  with  rapidity  and  accuracy.  Its  operation  is  simple  and  readily 
learned.  By  its  use  the  tedious  drudgery  of  calculation  is  avoided  and  the  chance  of  error 
eliminated. 

As  is  shown  in  the  illustration,  the  instrument  consists  of  a  cylinder  4  inches  in  diameter 
and  18  inches  long,  which  revolves  in  an  open  framework  composed  of  20  angular  bars  held 
between  two  metal  rings.  The  cylinder  bears  a  scale  corrsponding  to  the  scale  of  the  Slide 
Rule,  which  is  duplicated  on  the  exposed  sides  of  the  bars.  Results  can  be  obtained  to  the 
fourth  and  usually  to  the  fifth  place  of  figures  with  a  surprising  degree  of  accuracy,  sufficient 
for  nearly  every  requirement  of  the  professional  or  business  man.  Examples  in  multiplication, 
division,  proportion,  powers  or  roots  involving  not  more  than  three  quantities,  are  solved  by 
one  operation,  and  any  number  of  values  of  an  algebraic  function  composed  of  two  constants 
and  a  single  variable  may  generally  be  found  by  one  setting. 

The  useful  applications  of  the  instrument  are  almost  unlimited;  among  them  may  be  men- 
tioned finding  the  stresses  and  sections  in  trusses  and  girders,  mensuration,  estimates  of  work 
and  material,  solving  trigonometrical  formulas,  making  and  applying  tables,  problems  in 
mechanical  powers,  machinery  and  hydraulics,  problems  in  simple  and  compound  interest,  dis- 
count, prorating,  the  conversion  of  weights  and  measures,  cost  of  merchandise  with  per  cent

Fuller's  Spiral  Slide  Rule  consists  of  a  cylinder  which  can  be  moved  up  or  down  and 
turned  round  a  sleeve  which  is  attached  to  the  handle.  A  single  logarithmic  scale,  42  feet 
long,  is  wound  round  the  cylinder  spirally,  and  ratios  are  established  by  means  of  two  pointers 
or  indices,  one  attached  to  the  handle  and  the  other  to  an  axis  which  slides  in  the  sleeve.

The  use  of  this  Stadia  Reducer  involves  the  using 
of  only  such  vertical  angles  as  may  be  read  without 
the  use  of  the  vernier,  and  taking  the  vertical  difference 
and  horizontal  distance  directly  from  the  Reducer 
slide.  Results  are  given  for  these  angles  up  to  30  de- 
grees. The  height  cut  on  the  rod  by  the  middle  wire 
is  noted   for  a   correction. 

The  setting  of  the  telescope  to  an  angle  marked  by 
an  even  division  on  the  arc  can  be  quickly  and  ac- 
curately made  with  small  chance  of  error,  but  if 
desired  the  observer  may  mark  one  side  of  the  arc  and 
let  the  distinguishing  sign  appear  in  the  notes.  For 
example,  he  may  mark  the  minus  side  red  and  then 
an  angle  of  — 10°  could  read  red  10°. 

The  results  given  by  the  Reducer  are  those  obtained 
by  the  well-known  stadia  formula;  where  S  =  the  stadia 
distance,  V  =  the  measured  vertical  angle,  D  =  the 
horizontal  distance  and  H  =  the  distance  of  elevation 
to  the  point  sighted  on  the  rod.  Then  D  =  (S  -\-  f  -|-  c) 
cos2  V  and  H  =  (S  -f-  f  +  c)  #  sin.  2  V.  These 
formula?  are  practically  correct  for  vertical  heights  up 
to  15°  and  give  results  too  small  from  15°  up  to  30° 
by  the  amounts  given  in  the  following  table.  Horizontal 
distances  are  given  practically  correct  up  to  30°: 
Angle  of  inclination  1S°  20°  23°  25°  27°  29°  30° 
Error  in  vertical 

heights    0.01  0.02  0.03  0.04  0.05  0.06  0.07 

These  small  quantities  may  be  neglected  in  practice. 

Stadia  Reductions 


After  obtaining  the  stadia  distance  either  by  care- 
fully adjusted  wires  or  by  a  ratio  table  previously  pre- 
pared, add  the  f  +  c  for  obtaining  the  distance  argu- 
ment to  be  noted  on  the  top  of  the  Reducer  case.  Incline  the  telescope  to  the  nearest  division 
on  the  vertical  arc  that  will  keep  the  middle  wire  on  the  rod,  and  note  the  rod  reading  that 
the  middle  wire  cuts  for  a  final  correction.  Pull  out  the  Reducer  slide  until  the  angle  of  arc 
setting  shows  just  above  the  case.  On  this  same  line  on  the  slide  and  just  above  the  distance 
argument  on  the  case  find  the  difference  of  elevation  to  the  noted  rod  reading  cut  by  the 
middle  wire.  Correct  this  by  the  rod  reading  to  obtain  the  difference  of  elevation  to  the 
station  occupied  by  the  rod.  Without  moving  the  slide  find  the  horizontal  distance  on  the 
reverse  side. 

These  tables  are  also  to  be  used  after  the  manner  of  using  a  traverse  table.  For  example: 
Suppose  the  distance  argument  is  962  and  the  telescope  is  afterward  inclined  to  an  arc  reading 
of  — 11°  at  which  angle  the  middle  wire  cuts  the  rod  at  7.21.  A  foresight  computation  would 
then  be  as  follows: 

ON  THE  REVERSE  SIDE 

For  900    867.2 

For     60    57.8 

For       2     1.9 


ON  THE  FRONT  SIDE 

—7.21 

Difference    in   elev.    to   station 

—187.39 

Horizontal  distance    926.0 

The  Reducer  admits  of  being  used  to  carry  out  the  decimals  further  than  is  shown  in  the 
examples  if  greater  accuracy  is  desired.

THE  MARCHANT  CALCULATOR 


HE  value  and  importance  of  a  first-class  and  trustworthy  calcu- 
lating machine  to  the  civil  engineer,  construction  engineer, 
statistician  and  others  who  have  considerable  figure  work  to 
handle  has  long  been  conceded. 

Such  a  machine  is  a  great  labor  and  time  saver,  while  the 
relief  it  affords  from  wearying  brain  work  is  incalculable. 
The  Marchant  Calculator  (illustrated  above)  has  met  this  long-felt  want 
and  has  filled  the  requirements  and  demands  of  engineers  and  statisticians 
the  world  over. 

Pencil  and  slide-rule  methods  of  figuring  problems  are  fast  becoming 
obsolete.  The  up-to-date  mining  or  construction  company  can  no  longer 
afford  to  have  its  employees  spending  time  in  unnecessary  hand  figuring 
when  machine  calculation  has  been  perfected  to  such  a  degree  as  in  the 
Marchant  Calculator. 

The   Marchant  is  built  on  the  rotary  or  drum  principle.     This  principle 

can  be  appreciated  by  technical  men  as  the  best  for  direct  action  functioning. 

By  using  the  drum  principle  all  unnecessary  action  is   eliminated,   thus 

insuring  a  minimum  of  expense  in  upkeep — springs,  cams  and  other  parts 

used  in  machines  of  the  flat-bed  principle  being  entirely  done  away  with. 

Operation 

Unlike  many  of  the  machines  on  the  market  at  the  present  time,  the 
operation  of  the  Marchant  can  be  explained  and  taught  to  the  novice  in  a 
very  short  time,  it  being  unnecessary  to  engage  a  special  operator  to  per- 
form even  the  most  intricate  problems — the  Marchant  motto  being  "Do  it 
yourself  on  a  Marchant." 

Proof 

Every  calculation  performed  on  a  Marchant  is  instantly  proved,  no 
hidden  complements  to  memorize,  each  factor  and  result  is  at  all  times 
visible  to  the  operator.  It  has  been  found  that  the  proof  feature  saves 
100  per  cent  of  the  time  spent  on  rechecking,  as  is  often  the  case  when  using 
the  old  method  of  logarithms.  Time  and  absolute  accuracy  are  big  features 
and  important  ones  when  engineers  are  crowded  with  work.

THE  MARCHANT  CALCULATOR 

Models 

The  latest  model  Marcliant,  namely  the  Pony,  was  built  with  the  idea  of 
producing  a  light,  compact  calculator  of  such  convenient  size  that  it  could 
be  taken  to  the  job  or  moved  about  as  a  piece  of  hand  baggage,  and  yet 
having  all  the  well-known   features  of  the  standard  model. 

The  Pony  Model  is  built  in  two  styles — with  and  without  the  top  register 
dial.  The  top  register  dial  gives  a  complete  check  on  all  figures  operating 
on  levers,  a  feature  not  to  be  overlooked  by  the  engineer  who  is  constantly 
using  constant  multipliers  and  divisors. 

Application 

The  Marchant  will  handle,  in  a  fraction  of  the  time  ordinarily  spent,  all 
kinds  of  engineering  calculations.  Traverses,  averages,  square  root,  cube 
root,  assays,  assessments,  formulae  and  tonnages  can  all  be  handled  with 
rapidity.  A  typical  problem  of  the  mining  industry  with  which  the  average 
engineer  comes  in  contact  can  be  explained  thus: 

DISTRIBUTION  OF  METALS 
6948.82  tons  ore  assays  as  follows: 

0.129     oz.  gold  per  ton. 
5.72       oz.  silver  per  ton. 
3.225%  copper. 

Weights  Value 

6948.82x0.129  =  896.398  oz.  gold.  896.398  x20.6718  =  $18530.16. 

6948.82x5.72  =  39747.25  oz.  silver.  39747.25  x  689  =  $27385.86. 

3.225%  of  2000  lb.  =  64.5  lb.  per  ton.  448198.89x0.155  =  $69470.83. 
6948.82x64.5  lb.  =  448198.89  lb.  copper. 

SURVEYING  CALCULATION 

Bearing  34°  36'  E.  distance  295.76. 
Nat.  cosine  0.82314;  sine  0.56784. 
0.82314x295.76  =  243.452  northing. 
0.56784  x  295.76  =  167.944  easting. 

This  traverse  can  be  figured  easily  on  a  Marchant  in  forty  seconds. 

Operation:  Place  distance  or  295.76  on  machine  as  constant  and  multiply 
by  .82314.  Leave  figures  on  machine  and  interchange  multiplier  to  .56784, 
getting  second  result.    Point  off  seven  decimal  places  (5+2). 

A  fine  testimonial  from  one  of  our  largest  users  has  this  to  say: 

"The  machine  proved  itself  so  valuable  in  making  up  our  cost  statements 

and   in  verifying  ore  statements  that  we  purchased   five  more   Merchants. 

These  are  used  by  our  engineers  in  all  calculations  pertaining  to  tonnages, 

averages,  assays  and  percentages. 

(Signed)  "UTAH  COPPER  CO." 

Some  of  the  largest  mining  and  engineering  firms  in  this  country  and 
foreign  lands  are  using  the  Marchant  every  day  on  their  problems. 

Among  prominent  users  the  Marchant  numbers  as  its  endorsers:  Utah 
Iron  and  Steel  Co.,  American  Smelting  and  Refining  Co.,  International 
Smelting  Co.,  Ray  Consolidated  Copper,  Chino  Copper. 

Our  representative  will  deem  it  a  pleasure  to  demonstrate  the  wide  scope 
of  flexibility  of  the  Marchant.     Descriptive  literature  and  prices  on  request.

TRANSPARENT  LETTERING  ANGLES 


The  Lettering  Angles  are  de- 
signed to  give  a  quick  and  easy 
method  of  making  accurately  spaced 
guide  lines  for  lettering  drawings. 

There  are  six  columns  of  holes, 
the  columns  being  subdivided  into 
groups  of  three  holes,  the  holes  of 
each  group  being  joined  by  scored 
lines.  The  figure  under  each  col- 
umn denotes  the  height  of  the  stand- 
ard capital  letters  in  thirty-seconds 
of  an  inch.  The  standard  spacings 
between  groups,  also  for  the  lower 
case  letters,  are  two-thirds  the  height 
of  capitals.  The  purpose  of  three 
holes  in  each  group  is  to  enable  the 
drawing  of  three  guide  lines  for 
each  line  of  lettering,  when  it  is  de- 
sired to  use  both  lower  case  and 
capital  letters. 

The  Lettering  Angle  is  designed 
to  slide  on  the  hypotenuse  when 
making  standard  spacings,  but  either 
of  the  other  two  sides  may  be  used 
to  get  other  spacings. 

To  use  Lettering  Angle,  place  the 
pencil  point  through  a  hole  in  the 
desired  group,  and  slide  along  the 
T-square  or  another  triangle;  then 
place  the  pencil  point  through  an- 
other hole  and  slide  back.  The  Let- 
tering Angle  is  moved  along  very 
easily  by  the  pencil.  The  tapered 
holes  prevent  the  breaking  of  the 
pencil  point.  The  guide  lines  will 
be  very  accurately  spaced,  and 
drawn  much  more  rapidly  than  by 
laying  off  with  scale  or  dividers. 

The  lines  scored  across  the  Let- 
tering Angle  enable  one  to  obtain 
angles  of  15°,  30°,  45°,  60°,  75° 
and  90°  from  either  a  45°  or  60° 
triangle,  by  setting  these  scored  lines 
on  horizontal  or  perpendicular  lines 
on  the  drawing  board.  The  lines 
drawn  at  right  angles  and  parallel 
to  the  hypotenuse  are  particularly 
valuable  when  sketching  or  doing 
work  without  the  use  of  the 
T-square,  because  it  facilitates  very 
much  the  drawing  of  one  line  at 
right  angles  to  another.  These  lines 
being   scored   on   the   under    side    of 


Lettering  Angle,  throw  no  shadow,  whereas  the  edge  of  the  Lettering  Angle  does. 
The  bevel  pickup  makes  the  Lettering  Angle  very  easy  to  handle,

value  of  the  curve  contained.  Thus  the  required  curve  is  easily  picked  out,  and  the  chances  of  bending 
or  warping  the  curves  are  entirely  eliminated.

PARALLEL  STRAIGHTEDGE  OR  AUTOMATIC  T-SQUARE 


Nos.  3407-8 


The  Parallel  Straightedge  consists  of  a  set  of  two  double  pulleys 
attached  to  the  back  corners  of  the  drawing  board,  and  two  single  pulleys 
attached  to  the  front  corners.  A  steel  piano  wire  is  placed  around  these 
pulleys,  making  a  double  lap  along  each  end  and  back  of  the  board  but  no 
wire  across  the  front.  By  crossing  the  wire  at  the  back,  the  upper  laps  at 
both  ends  must  move  forward  and  back  simultaneously. 

The  ends  of  the  wire  are  joined  together  at  the  back  through  a  steel 
spring.  Both  ends  of  the  straightedge  are  attached  to  the  upper  wires  at 
the  ends  of  the  board  by  binding  posts,  thus  making  it  possible  to  move  one 
end  of  the  straightedge  without  moving  the  other  a  corresponding  amount 
in  the  same  direction. 

All  pulleys,  brackets  and  binding  posts  are  made  of  brass,  accurately 
machined,  highly  polished,  and  lacquer  finished.

No.  3505 


The  Hoffman  Artist's  Drawing  Stand  No.  3505  and  Drawing  Board  Bracket  No.  3507  are 
strongly  constructed  of  steel  tubing  and  iron  castings,  fitted  up  in  the  best  possible  manner 
and  handsomely  finished  in  nickel  and  black  enamel,  making  a  very  attractive  and  most  useful 
article. 

By  means  of  the  Drawing  Board  Bracket  No.  3507  a  drawing  board  may  be  attached  to 
anything  that  has  a  clamping  edge,  while  the  Artist's  Stand  No.  3505  has  a  tripod,  which 
makes  it  complete  in  itself.  Either  the  bracket  or  the  stand  may  be  purchased  and  later  one 
converted  into  the  other  by  adding  the  tripod  or  the  clamp  to  the  equipment. 

With  either  arrangement  the  drawing  board  can  be  adjusted  instantly  to  any  desired 
height,  tilted  and  locked  at  any  angle,  from  horizontal  to  vertical,  and  revolved.  The  outfits 
are  light  and  easily  transferred  from  office  to  home  or  the  field.  After  removing  three  nuts 
from  the  brace  which  connects  the  tripod  it  will  fold  and  pack  in  the  box,  4^x5x24  inches.

THE  "AVALON"  DRAWING  TABLE 

With  Roller  Adjustment 


No.  3520 


The  Avalon  Drawing  Table  is  very  substantial  and  rigid.  It  is  36  inches  high  and  can  be 
raised  to  48  inches.  This  can  be  accomplished  by  turning  the  large  handwheel.  The  slides  are 
carried  between  roller  bearings  on  the  standards,  and  move  with  perfect  freedom  from  friction, 
and  without  the  grating  sound  of  sliding  metal  surfaces. 

The  slides  may  be  locked  at  any  desired  height,  by  means  of  a  hand  nut  easily  reached  by 
one  hand  while  the  wheel  is  being  manipulated  by  the  other.  The  tightening  of  this  nut 
releases  the  inner  roller  and  substitutes  a  frictional  bearing  on  bases  attached  to  the  standards, 
forming  an  efficient  clamp.  In  addition,  by  the  same  operation,  the  ends  of  the  pinions  are 
locked  against  the  faces  of  the  slides,  rendering  their  revolution  impossible  and  doubling  the 
security  of  the  clamp.

THE  DREW  METHOD  FILING  CABINET 

The  Drew  Method  of  Filing  as  manufactured  by  us  was  primarily 
conceived  to  overcome  the  lost  floor  space  as  occupied  by  the  drawer 
method  and  the  inconvenience  of  taking  drawings  therefrom.  Compact- 
ness and  accessibility  are  paramount.  The  drawer  method  of  filing  needs 
no  mention  from  us  as  to  its  faults,  for  anyone  who  has  had  to  resort  to 
maps  or  drawings  when  filed  in  this  manner  knows  of  its  shortcomings. 
It  can  today  only  be  regarded  as  obsolete. 


Maps  may  be  altered  without  detaching. 
No.  3590— Illustration  1. 

The  Drew  Method  Filing  Cabinet  consists  of  a  Cabinet  5  feet  10  inches 
high  and  15  inches  deep,  on  which  sections  18  or  36  inches  in  height  may 
be  added  as  additional  filing  space  is  required. 

The  maps  are  attached  to  detachable  spring  rollers,  or  thin  tracing  paper 
sketches  can  be  conveniently  filed  in  metal  containers.  An  idea  of  the 
filing  capacity  of  the  Drew  Method  Filing  Cabinet  can  be  gained  when  one 
realizes  how  easily  15  maps  of  varying  sizes  and  lengths  can  be  mounted 
in  juxtaposition  on  each  roller.  When  required  the  desired  map  can  be 
drawn  from  its  position  on  the  roller  for  examination,  which  the  other  maps 
on  the  same  roller  will  fall  automatically  out  of  the  way.  The  front  of  the 
cabinet,  when  lowered,  serves  as  a  table,  on  which  the  maps  may  con- 
veniently be  examined  or  altered,  without  detaching  from  the  roller.  When 
fully  wound,  the  maps  are  kept  from  unraveling  by  means  of  metal  spring 
clamps. 

Thin  tracing  paper  sketches  are  filed  in  the  metal  containers  and  can 
easily  be  taken  out  for  examination  by  means  of  pull-cords  which  slip  under 
the  tracings. 

The  rollers  and  metal  containers  are  made  in  two  standard  widths,  45 
and  60  inches,  and  are  hung  about  5  inches  apart  on  two  endless  chains 
which  revolve  on  geared  wheels,  so  that  any  roller  or  container  can  be 
instantly  brought  in  position  for  examination.  The  rollers  and  metal  con- 
tainers are  interchangeable  and  the  desired  number  of  each  can  be  furnished.

THE  DREW  METHOD  FILING  CABINET 


Illustration  No.  2  shows  Drew 
Method  Filing  Cabinet  when  closed. 
This  cabinet  is  5  ft.  10  in.  high,  on 
top  of  which  rests  a  section  18  in. 
high.  Extra  units  may  be  added 
to  admit  the  heightening  of  the 
cabinet  when  additional  rollers  are 
needed. 

The  cabinet  as  shown  embodies 
36  rollers,  on  which  maps  of  vary- 
ing sizes  and  lengths  can  be 
mounted. 


Illustration  No.  2 


Illustration  No.  3  shows  how 
conveniently  the  Drew  Method 
Filing  Cabinet  is  lowered  or 
closed.  The  table  drop  is  coun- 
ter-balanced by  heavy  springs, 
which  control  its  action.  When 
fully  opened  the  front  of  the 
cabinet  serves  as  a  table  con- 
sisting of  a  pinewood  board  on 
which  alterations  may  be  made 
to  maps  without  detaching  them 
from  the  rollers.  The  table  may 
be  enlarged  by  bringing  the 
folding  leaf  into  a  lateral  posi- 
tion, where  it  is  firmly  held  by 
means  of  the  two  hinged  sup- 
ports. A  footrest  is  also  in- 
serted for  convenience  wher, 
working  about  the  cabinet.

The  cabinets  are  built  of  either  wood  or  steel  and  can  be  finished  to 
match  the  general  scheme  of  an  office.

THE  BAXTER  FILING  SYSTEM 

This  system  of  filing  of  drawings  was  brought  forth  by  F.  K.  Baxter, 
of  one  of  the  Oil  Companies  of  California. 

Confronted  with  the  old  problem  of  limiting  the  space  required  for  the 
filing  of  the  company's  drawings,  Mr.  Baxter  set  about  to  conceive  a  method 
of  throwing  out,  rather  than  adding  to,  the  already  large  number  of  drawing 
cabinets  in  use  by  the  company;  floor  and  room  space  was  in  demand  and 
limited.    Necessity  certainly  proved  the  mother  of  invention  in  this  instance. 

The  illustration  on  opposite  page  shows  over  1600  drawings  of  all  sizes, 
lengths  and  widths  most  conveniently  hung  in  place.  The  drawings,  nega- 
tives or  tracings  are  reinforced  at  the  upper  end  with  strips  of  heavy  gummed 
paper,  which  will  support  the  heaviest  maps  without  tearing,  suitably 
punched  to  be  placed  on  pins  suspended  on  rods  fastened  to  traveling 
carriages  about  12  inches  wide  when  closed  and  in  series,  permitting  of  a 
separation  to  allow  for  the  examination  of  the  maps,  thus  affording  acces- 
sibility to  the  cabinet,  as  shown  in  illustration. 

Invariably  one  wishes  but  to  examine  a  drawing  for  the  purpose  of 
ascertaining  the  location  of  some  property  or  bearing.  It  is  only  necessary 
to  run  the  hand  between  drawing  and  the  adjoining  sheet  (after  locating  the 
desired  copy  by  means  of  the  index)  to  examine  it  at  will  or  without  in- 
terference. 

But  should  it  be  necessary  to  take  the  map  from  its  place  in  the  cabinet, 
the  gun-shaped  hand  (standing  at  end  against  folding  door  shown  in  illus- 
tration) is  inserted  in  back  of  the  desired  map  and  a  small  locking  pin  is 
pulled  down,  opening  the  carriage.  The  maps  on  the  one  side  remain  locked 
on  the  carriage  by  means  of  the  gun-shaped  hand  while  the  rest  travel 
away  from  it.  The  map  is  then  brought  forth  to  be  printed,  examined  or 
retraced,  as  the  case  may  necessitate.  An  index  card  is  placed  in  the  rack 
in  lieu  of  the  map,  on  which  is  noted  the  whereabouts  of  the  map  proper. 
When  the  map  is  no  longer  required,  it  is  placed  upon  a  suitable  rack  at  end 
of  cabinet  (as  shown  in  illustration)  until  evening,  when  all  are  readily 
placed  in  their  proper  location  in  the  file,  the  person  filing  being  guided  by 
the  index  number  on  the  edge  of  the  drawings. 

A  curtain  shade  is  drawn  down  over  the  whole  when  not  in  use,  the  folding 
iron  gate  is  swung  into  place  and  the  cabinet  containing  all  the  valuable 
drawings  is  secure  against  molestation. 

State  your  required  capacity,  the  dimensions  of  your  allowable  or 
suitable  space  and  we  will  work  out  your  problem  and  quote  you  accordingly.

This  accessory  enables  the  draftsman  to  fill  his  pen  in  the  shortest  possible  time,  and  by 
the  use  of  one  hand  alone,  leaving  the  other  at  liberty  to  hold  the  T-square,  triangle,  etc.  It 
will  serve  as  a  paperweight  and  the  stand  being  sufficiently  heavy  offers  a  stability  the  need 
of  which  is  so  strongly  felt  when  working  without  a  holder  for  the  bottle.  Provided  with  an 
automatic  stopper,  most  efficient  in  preventing  evaporation,  and  the  new  form  of  dipper  will 
instantly  and  positively  deliver  an  ample  and  uniform  charge  with  no  tendency  whatever  to 
ink  the  outside  of  the  blades.     Made  of  cast  iron,  japanned.

TRIANGULAR  POINTS  A  <<^ 


The  Worth  Lettering  Pen  is  the  most  recent  innovation  in  pens  par- 
ticularly intended  for  the  lettering  of  maps  or  the  writing  of  showcards, 
price  tags,  etc.  The  large  capacity  of  the  ink  reservoir  makes  it  superior 
for  drawing  heavy  border  or  long  contour  lines  without  refilling. 

The  improvements  of  the  Worth  Pen  consist  primarily  of  the  inter- 
changeability  of  the  pen  points,  the  convenient  method  of  filling  and  the 
rapidity  with  which  it  is  cleaned. 

The  triangular  shaped  point  finishes  each  letter  with  a  square  edge. 

The  Worth  Lettering  Pens  are  sold  either  separately  or  in  sets,  con- 
sisting of  one  holder  and  six  different  size  nibs,  as  per  above  illustration.

INK  ERASER 

MOTOR  DRIVEN  TYPE 

This  outfit  consists  of  a  rapidly  re- 
volving circular  eraser  driven  through 
a  flexible  shaft  3  feet  long  by  means 
of  a  small  motor,  which  may  be  at- 
tached to  any  convenient  lighting 
socket  and  will  operate  on  either 
direct  or  alternating  current.  A  clean- 
ing rubber  is  arranged  to  touch  the 
rotating  circular  eraser  very  gently 
and  remove  the  ink  which  would 
otherwise  collect;  adjustment  is  made 
by  the  movement  of  a  sleeve  on  the 
handle  of  the  erasing  head.

BOURGEOIS'  FRENCH  WATER  COLORS 

| 


Nos.  4121-4125 


The  Bourgeois  French  Water  Colors  are  put  up  in  glass  jars 
containing  more  than  twice  as  much  as  the  whole  pans  sold  by  other 
manufacturers  at  about  the  same  price.  They  are  moist  and  a  slight 
rubbing  of  the  desired  colors  with  a  moistened  brush  is  sufficient  to 
obtain  the  full  richness  of  their  tint.  The  colors  are  very  brilliant 
in  tone.

Contents. — Preliminary  Considerations;  Bending  Stresses;  Shear  Stress; 
Floors  and  Buildings;  Foundations  and  Rafts;  Retaining  Walls;  Bridges; 
Arches  Bridges;  Sleepers,  Fence  Posts,  etc.;  Summary  of  Notation  Em- 
ployed. Aims  to  describe  the  generally  accepted  principles  and  processes 
upon  which  the  design  and  construction  of  reinforced  concrete  structures 
depend,  and  more  especially  those  structures  that  come  within  the  railway 
engineer's  practice.  Complicated  formulas  and  calculations  have,  as  far 
as  possible,  been  avoided  and  the  attention  concentrated  upon  arriving 
at  results  as  simply  as  possible  and  presenting  them   conveniently.

This  volume  contains  a  number  of  computing  diagrams  giving  rapid, 
approximate  solution  of  the  common  problems  in  the  design  and  con- 
struction of  electric  power  systems  and  similar  undertakings.  Beginning 
with  the  design  of  foundations,  arches  and  reinforced  concrete  walls,  the 
strength  and  dimensions  of  all  necessary  material  can  be  readily  deter- 
mined. Stadia  readings  can  be  quickly  reduced,  the  capacity  of  pipes  and 
flumes  easily  found,  the  economic  size  of  pipe  selected  and  the  weight  of 
material  for  wood-stave  or  steel  pipe  lines  determined.  Where  steam  is  to 
be  used  the  horsepower  of  different  sized  engines  can  be  mechanically 
determined  and  the  power  transmitted  by  shafting,  gearing  and  belting 
calculated.  Electric  wiring  problems  and  those  of  pole  line  construction  are 
worked  simply  and  the  comparative  cost  of  power  easily  shown.  All  this 
and  more  may  be  done  without  knowledge  of  mathematics  by  the  simplest 
mechanical  process;  no  handbook  nor  slide  rule  nor  table  of  logarithms  is 
necessary  in  any  of  the  problems  covered.  Detailed  explanations  and  typical 
examples  are  given   on  the  page  opposite  each  of  the  diagrams.

This  is  a  broad  consideration  of  many  moot  questions  of  rate  regulation 
and  valuation.  The  author's  wide  experience  and  successful  work  in  con- 
nection with  many  such  cases  involving  water  and  power  companies  make 
his  thoughts  most  valuable  to  anyone  concerned  with  rate  fixing.  He  con- 
tends that  accrued  depreciation  should  not  affect  rates,  he  discusses  the 
relation  of  the  water  right  valuation  to  rate  base,  and  presents  valuable 
data  on  appraisal  of  real  estate  in  utility  service.
