The Hallidie Ropeway consists of a single endless moving wire rope 
passing around horizontal grip pulleys or sheaves at the extremities of 
the line [Figs. 2 and 3], and being supported at intervals by towers car- 
rying supporting sheaves. [See frontispiece.] To this rope the carriers 
are securely fastened, and hence as the rope travels it moves the carriers 
and their loads with it. 

A general idea of the main features is given in Figure i. Near the 
mouth of the tunnel, and somewhat below it, is the upper terminal of the 
Ropeway, which contains the grip pulley with the brake and the fair 




Figure 1. 



leader sheaves. The ore from the mine is dumped into bins near the 
Ropeway, and from them loaded either by hand or mechanically [see Figs. 
30 and 31] into the moving buckets of the Ropeway. From the terminal 
the line passes over the sheaves on the towers, which are set one hundred 
feet or more apart, as the local conditions require. Where there are canyons 
or valleys to be crossed, the span is increased, as the tension in the rope 
will lift it so high above the ground that it will be impossible to place a 
tower. Such a span is showm about the middle of the line in Fig. i. 
These spans do not in any way interfere with the working of the line, 
and we have lines working satisfactorily which contain spans over 2,000 
feet long. The lower terminal, containing the horizontal sheave, is placed 
over the ore bins in such a position that the buckets dump their loads into 



307G^a 




Fig. 2 



tbe bins. From the bins the ore can be sent directly to the milling 
machinery. Having discharged their loads, the rope and buckets pass 
around the terminal and up over the sheaves on the other side of the 
lowers to the upper end, where they are reloaded. 

The Dead Weight and Cost of the machinery in this system is 
reduced to a minimum; as there is but one rope employed which travels 
with the load attached to a clip fixed to the rope, the weight of the material 
employed in its construction is about 60 per cent, of the weight of the 
apparatus where the two ropes [Standing and Hauling Ropes] are 
employed, and consequently cost less in proportion, both in first cost and 
maintenance. 

In transporting the material used in constructing a Ropeway over the 
trails or roads of the mountains, there is consequently a considerable item 
of expense saved on transportation and freight alone. (See Figs. 18, 19 
and 20. J 

The Care of Machinery and apparatus in the mountains, remote 
from repair shops, mechanics and material, is a matter of serious moment, 
and any one who has had experience in such a region can fully appreciate 
this. Reduce the parts liable to get out of order and you reduce the cost 




of maintenance and repairs and increase the efficiency of any apparatus 
that has to be manipulated largely by unskilled labor. 

In the HAIyLIDIE ROPEWAY every superfluous part is dispensed 
with ; the Ropeway itself is reduced to a minimum of simplicity. 

The Inspection of the Cable is a very simple matter, as the only rope 
used, and on which so much depends, passes constantly before the eye 
of the man in charge, who can detect at any time any imperfection or in- 
jury existing on any part of the rope. 

In a standing or fixed rope this is not the case, as a man has to be 
sent out to make a special examination, and at best an imperfect one; 
and where both a standing and a running rope are employed, a separate 
inspection must be made of each of them. 

The Terniinal Structures (Figs, ii, 12, 13 and 14), consist of heavy 
timbers, thoroughly framed and bolted together. To it are fastened the 
boxes for the end sheave or grip pulley and the castings for the small 
sheaves or fair leaders that guide the rope on to the large terminal sheave. 
In most cases we ship only the bolts for the structure, and the timbers are 
obtained near the site of the Ropeway and framed on the ground. Occas- 
ionally we furnish the timber work also, in which case the parts are all 



properly marked and the frame knocked down for shipment. Where it is 
necessary to pack the timbers by mules the long ones are cut in two and 
furnished with splice plates. 

Each terminal frame contains 1,515 feet B. M., making ample allow- 
ance for all tenons but none for waste. 

The upper terminal is usually anchored securely to the bed-rock as 
shown in Fig. 7, and the rope led out horizontally for loading and until 
it is high above the ground. 





A set of complete drawings is furnished with each tramway, showing 
the construction of all the mechanisms. 

The Grip Pulley is used to transmit power either to or from the rope. 
To the rope when it is necessary to drive the Ropeway by power, and 
f7077i the rope when a line is operated by gravity and furnishes power to 
drive other machinery, or the extra power is absorbed by the brake at- 
tached to the Grip Pulley. This Pulley has been improved from time to 
time, and three patents have been issued to Mr. Hallidie for the same, the 
last of which is dated September 27, 1892. 

By referring to Figures 4 and 5 it will be seen that there are a num- 
ber of grips or hinged jaws attached to the periphery of the pulley into 
which the rope enters, and pressing on the bottom of the jaws causes them 
to grip or close over the rope, the amount of gripping power being deter- 
mined by the length and travel of the jaws and the pressure from the rope. 

Formerly the jaws of the grip rested in pockets cast in the periphery 
of the pulley, but it was found impracticable to get the pockets of uniform 
depths and many of the grips were useless in consequence. Such a grip 
pulley is now being made by other tramway companies. In the improved 
Grip Pulley the pockets are done away with and a continuous groove 
takes their places, insuring uniformity of distance, duty of every grip.

and greater simplicity in construction. The grips are held in positionby 
webs cast on them, which fit loosely into slots in the outer edge of the 
pulley. (See Fig. 5.) The Grip Pulley and attachments are built up of 
parts which can be separated and put in parcels to pack on mule back, as 
are all the other parts of the Hallidie Ropeway. (See Figs. 18, 19 and 
20.) Every part is marked and can be put together on the ground by an 
intelligent mechanic. 

The power to operate the Ropeway is derived either from the weight 
of the material being transported, or from some external source of power, 
be that a line shaft, an engine, a water wheel or other prime mover. 
(See Figs. 12 and 13.) When the point of discharge is lower than the 
loading point, and the delivery is five tons or more per hour, the line will 
operate by the weight of the descending load under ordinary conditions, 
provided the grade exceeds eight degrees or one fall in seven horizontal. 
In such cases the speed of the line is controlled by means of a wood- 
lined band brake (see Figs. 11 and 14), operated by a hand wheel and 
screw and clamping the brake wheel bolted to the grip pulley. 

For heavy lines a brake may be placed on both sides of the grip 
pulley, and occasionally a grip pulley and brake are used at the lower end 
also, but usually in gravity lines a plain sheave is used there. The man 
having charge of the loading attends to the brake also. 

Where the line is on an incline less than eight degrees, or the loading 
point is lower than the discharge end, it is necessary to supply the line 
with power from outside, either from the mill shaft or from a special 
motor. For this purpose a bevel gear is bolted to the grip pulley, instead 
of brake wheel, and it is driven by a bevel pinion on a countershaft. 
(See Figs. 12 and 13J 

When the angle of descent is very great, the descending load furnishes 
sufficient power to carry back and up to the mine such material as may 
be needed; and, in several lines we have constructed, this saving when 
taken into account, has been so great that it not only brought the cost of 
transporting the ore to nothing, but has actually been a source of revenue. 
Again, in cases where power is needed at the mine for pumping, 
crushing ore, etc., the Ropeway can be used either to furnish the power 
or to transmit it from the mill end. Fig. 6 shows a rock-crusher con- 
nected to the grip pulley by gearing and operated by the Ropeway. If 
the grade is steep enough, the line may generate enough extra power to 
do this work, but if it does not, the endless rope can be used to transmit 
the power delivered to a grip pulley at the lower end to the grip pulley 
at the upper end, to which the machinery can be connected. This work 
will not interfere in any way with the regular duty of the Ropeway 
of carrying ore. 

The Tig'htening- Apparatus, for keeping the line taunt under all 
conditions ot temperature and load, consists of a strong wooden box filled

with rocks or old iron and attached to the end of a wire rope which 
passes over sheaves, suitably arranged, to the rear of the terminal which 
is set on wheels running on a track. By this means any slack occuring 
in the line is taken up by the counterweight. Figures 8, 9 and 10 are 
sketches of the several ways of arranging the tightening apparatus under 
tue conditions most likely to occur in practice. Illustrations from actual 
construction are given. (See Figs. 2 and 47.) 

The Intermediate Towers are built of substantial timbers generally 
twenty feet long, making a tower about eighteen feet high. These keep 
the rope sufficiently high so that the buckets will clear brush or snow. 

To the ends of the cross-arms of the towers are fastened the iron 
station frames which carry the supporting sheaves for the rope. (See 
front'spiece.) We have a large number of patterns for these sheaves, of 
various designs and strength, which we use according to the reqiiire- 
ments of the case. The grooves of the sheaves are chilled, and are made 
of a special grade of iron. (See Fig. 43.) Usually, however, the sheaves 
along the line are 22" in diameter, but where a sharp angle is made we 
often use a 30" sheave. 

Figure 15 gives a very good view of one of these towers as built on 
the Hall Mines R.^^peway. (Also see frontispiece.) From its shape Inis 



14 






Fig. 16. 



form of tower has been nick-named the A X tower, as the side view of it 
is a perfect A and the end view is an X. 

Where the nature of the ground is uneven, a higher station is often 
needed, as seen in the distance in Figure 15, in which case the regular 
A X tower is placed on a rectangular base to bring it up to the required 
height. Such a tower seventy-five feet high is shown in Figure 17. This 
is a better arrangement than to design a special tower for each place, as 
all the upper parts can be framed from the same templates and the bases 
built of rough timber on the site of the towers. 

In places w^here there is danger of snow slides, a simple mast of very 
heavy timber or a bunch of two or three masts can be set in the ground, 
a cross-arm set at the top and the whole securely guyed. As this offers 
less resistance to a slide there are more chances of its dividing and pass- 
ing around the mast than around a tower with a base twelve or more feet 
square. If, however, a tower is swept away, the line itself is not injured, 
the only loss being that of the tower itself. 

On very steep bluffs it is sometimes easier to secure a simple X frame 
by anchoring the base and gujang the top than it would be to obtain a 
footing for the regular towers. 

The Rope used on our Ropeways is of the class known as " flexible 
crucible steel rope," and is usually made of six strands laid around a

hemp center, and each strand consisting of nineteen wires. The size of 
the rope is determined bj^ the work to be performed, the usual sizes being 
%", }i", and i" diameter. 

The rope is usually shipped on reels holding several thousand feet, 
but where the upper part of the line is inaccessible to wagons, the rope.

like the rest of the machinery, must be packed so that it can be loaded on 
mules. (See Figs. i8, 19 and 20,) We make a specialty of coiling our 
cables so that they can be easily transported in this way, even when 
thousands of feet long and weighing several tons. Figures 18, 19 and 20 
are from photographs of trains of mules packing cables along trails. Each 
animal carries about two hundred and fifty pounds, including the piece of 
slack rope fifteen or twenty feet long connecting its load to the next one 
in the rear. This piece is usually held up by a native so that it will not 
drag on the ground. 

In stretching the rope the simplest way is to set up the reel of rope 
at the upper end and drag the end down the line by means of a mule, and 
as each station is passed it is raised on to the sheave. When one side is 
all out the upper end is made fast and the other side is stretched out in 
like manner. The upper two ends are then spliced together, and after 
one of the lower ends has been passed around the tower sheave the ropes 
are drawn up to the proper tension and the last two ends spliced together. 
The counter- weight rope and box is then attached to the lower terminal 
and loaded. 

While in service the rope should be coated frequently with a mixture 
of pine tar containing one-tenth raw oil, boiled together and applied warm. 
Care must be taken not to burn the tar in boiling or its virtue will be lost. 
This coating lubricates the wires and prevents unnecessary internal wear 
of the rope. 

The Clip is used to attach the loads to the rope, and is so designed 
that it will pass the end sheaves and also go over the sheaves along the 
line. (See Figs. 21 and 44.) 

The Strap Clip (Fig. 44), patented February 12, 1892, is the result 
of careful thought, time and experiment. It is made of steel, and con- 
sists of five parts — a shank, the leaf or strap, a key, a bolt and a nut. 
The strap surrounds the rope, and, by means of the bolt and nut and key 
holds the shank in position. The key is used to tighten up the strap 
when the rope becomes smaller or the strap becomes larger by wear. The 
strap, when worn out, is removed by driving out the key and removing 
the bolt. A new strap is then put on and secured by the bolt and key as 
before in a very few minutes, and at small cost. 

The Center Clip (Fig. 21), patented May 9, 1899, No. 624648, is the 
most simple clip on the market. It is made in halves and drop-forged. 
The life of this clip is incalculable. 

This clip has been tested under hanging loads, and sustained a load 
of 2,000 pounds before showing au}^ weakness, and 2,500 pounds before 
being sufficiently distorted to prevent its passing the station sheaves and 
horizontal end pulleys.

Fig. 22. 



The Ore Bucket (Figs. 22 and 29), is self-dumping and is attached 
by a hanger directly to the lugs of the clips by a bolt and nut. (See Fig. 
22.) The carrier complete weighs about seventy pounds, and contains 
one hundred to one hundred and twenty-five pounds of ore. Under this 
arrangement the load is fixed to the rope and travels with it, and the 
carrier is filled while passing and while the rope is moving at a speed of 
about two and a half to three feet per second. It is not, however, neces- 
sary that the load should be fixed to the moving rope, nor that the load 



20 






should be limited to one hundred pounds in weight, as each clip, as or- 
dinarily made, is capable of holding two hundred and fifty pounds under 
a factor of safety of eight, and the number of clips can be increased to any 
reasonable number desired and the load increased in proportion, but the 
most satisfactory and economical result in delivering ore, or similar 
material, can be obtained by single loads of from one hundred to two hun- 
dred and fift}^ pounds. 

Although the clip is always attached securely to the rope, for the 
reason that it shall not slip at any angle of the rope, and thus the weight 
of the descending load is taken advantage of to carry the ascending load» 



21

22 

the carrier and its load can be attached or detached at will by an interme- 
diate connection, and, where heavy loads are transported, this is usually 
done, and the load run on to and off from the clip-hanger as required. 

In addition to the buckets for ore, we make special carriers for special 
loads. Figure 23 illustrates an automatic dumping sling for a cask. In 
this case two clips are used, as the load was five hundred pounds. Figure 

23 shows the bundle carriers used on the line recently furnished for carry- 
ing baggage and supplies over Chilcoot Pass on the route to the famous 
Klondike district in the Northwest Territory. (See Fig. 39.) Figure 

24 is a drawing for a wood or cane basket. It has been used extensively 
in the Hawaiian Islands for carrying sugar cane. (See Fig. 45.) The 
carriers are loaded in the field by depressing the rope so that the native 
laborers can throw in the cane as they pass. The}' are dumped on the 
apron at the mill by tripping the latch. 

This illustrates a few types of carriers. We make them to meet the 
requirements of any class of materials. (See Fig. 25.) 

In Figure 6 is a sketch of hand-loading platform, bin, etc. 

In loading merchandise it is usual to attach by hand, as the varying 
conditions and shape of the loads prohibit passing them through any 
mechanism, but where a quantity of the same class of goods is con- 
stantly handled, platforms can be arranged to make the operation simple. 
Figure 27 illustrates a bundle of wire in transit at our factor}^ having 
just been loaded from the platform. 

The Loadings of the Carriers can be done by hand or automatically. 

In some cases where the amount to be handled is small, the best way 
is to dump the ore from the mine on a smooth floor of sheet iron, and 
then shovel by hand labor directly into the ore carriers as they slowly 
pass in front of the ore dump, a little above the level of the floor. (See 
Fig. 6.) The ore carriers move at a speed of about two and a half to 
three feet per second, and a scoop shovel will fill the carriers with one 
hundred pounds of ore each. With one man two to three tons can be 
handled and conveyed over the line each hour. 

Where the amount of ore exceeds two or three tons per hour, or the 
cost of labor is high, the loading may be done mechanically, in which 
case one man will load ten to twenty-five tons per hour, and can also 
attend to the brake or driving machinery if conveniently arranged. 

The Mechanical Loader manufactured by this Company, and shown 
in side and end elevation by Figure 30, is the simplest and most efficient 
mechanical device ever invented for the purpose. There is nothing to 
get out of order and very little to wear out. It is placed in front of the

ore bin and receives the ore from the chute, whence it is discharged into 
a loader hopper at the foot of a pendulum. The details of the part that 
actually do the loading are shown in the photographic view, Figure 31. 
The device consists substantially of a pendulum swinging on trun- 
nions about tweut}' feet above the level of the moving cable. The pen- 
dulum is made from sheet-iron tubing twelve inches in diameter. At the 
lower end is attached a loading box which contains, when loaded, enough 




Fig. so. 

ore to fill one carrier of the Ropeway. The loader hopper has two sides, 
a back and a sloping bottom; the front of the hopper is open. While the 
hopper is being loaded it is held between a guide and a fixed door or 
bulkhead, which closes the open front. 

The releasing of the hopper box is done by the clip on the moving 
cable to which the ore carrier is suspended, and which as it moves along 
strikes the end of a lever which raises the latch ofi" its keeper. At the 
time the loading box is released the ore carrier is immediately under the 
nose of the loader box ready to catch the contents of the box. The clip 
on the moving cable then pushes the hopper out from behind the fixed 
door, at the same speed as the carrier, and thus opens up the front of the 
loader box and lets the contents pour into the carrier. The swing of 
the pendulum raises it su65ciently high after a few feet of travel to clear 
the rope clip, and the pendulum with the empty hopper swings back by 
gravity in between the guide and the bulkhead ready to receive another 
load of ore from the ore bin. 

A working model of the mechanical loader in connection with a 
tramway can be seen at our San Francisco or Seattle office. 



26 




Unloading of Carriers is done automatically, with bulk merchandise, 
ore, etc., by a latch on the carrier striking a trip, but with irregular 
packages or goods that will not stand dumping, the carriers are unloaded 
by hand. 

Figure 29 shows the regular bottom dump bucket in the act of dis- 
charging, The latch has just struck the trip and the weight of the ore 
has opened the bottom and is discharging itself into bins. 

Horizontal Angles are sometimes necessary in order to avoid some 
obstacle that is easier to go around than to go over, but they should be 
avoided where practicable, as they add to the cost of construction and 
usually increase the length of the line. As a general rule it is simpler to 
run a Ropeway over an elevation than to go around it, because the ver- 
tical angle can be made with but slight changes in the machinery and no 
increase of cost, while the horizontal one requires an angle station of 
special construction and increases cost. 

This is due to the position of the clips and hangers. As they hang 
on the outside of the rope it is necessary to have all the supporting 
sheaves and horizontal sheaves on the inner side. When it is necessary 
for both lines of the Ropeway to turn a horizontal angle the sheaves have 





Fig. 33. 



to be arranged as in Figures 32 and 33. The rope on the outside of the 
angle can be carried around a single sheave A, as the hangers will be on 
the outside, but the inner rope, which should be the empty one, must be 
carried across and over the other or loaded rope to sheave B, then around 
it and over to C, then around it and over both the loaded and itself near 
sheave A, and on to the next regular tower. The ropes have to cross each 
other so as to clear by seven or eight feet in order to let the buckets pass 
without fouling the rope beneath. Where the ground will permit, the 
stations are set so as to get the difference in elevation of the rope by the 
natural topography of the country, as in Figure 32, but where this is-

impracticable a special angle tower must be built of the t3'pe shown in 
Figure 33. But each case has to be worked out for itself as each angle 
varies. 

A Profile of the line of the proposed Ropeway should be made from 
an accurate survey, in order to determine the height and distribution of 
the towers and the arrangement of the machinery to suit the case best. 
The profile should be drawn to as large a scale as practicable, and the 
same scale should be used for both the vertical and horizontal distances. 
The profile furnishes the foundation for an estimate, and serves as a 
guide in erecting the Ropeway. 




Illtjstrations from Practice. Profile No. i, in the back of this book, 
is a profile of the Ropeway for the San Juan Mining Company, 12,360 
feet long, and illustrates the principle of placing stations on the high 
points in the mountainous country, thus practically reducing the broken 
country to a uniform grade without doing any cutting and filling as in 
surface roads. On reaching the flatter country at the foot of the hill, the 
stations are placed at regular intervals, as there are no topographical 
features to be accommodated. 

Profile No. 2 is a profile of the White Cloud Mining Company's 
Ropeway in Nevada, 3,790 feet long, and illustrates very clearly the ease 
with which the Ropeway can be made to overcome the enormous irregu- 
larities of the country, which for an}^ other means of transportation would 
form an insurmountable barrier on account of the great cost of construc- 
tion. How many miles of railroad would it take to bring the ore down 



30 




the 1,351 feet which is here done by 3,790 feet of Ropeway? Look at 
the grading and trestles required for an incline plane along this same 
profile. 

The Longest Line we have built is one for the Hall Mines, British 
Columbia, which is 23,797 feet long — nearly four and one-half miles. Our 
Figures 15 and 17 are taken from photographs of this line. Much of the 



31 

line is through dense forests, and a path two hundred feet wide had to be 
cut for the Ropeway as a protection against forest fires and falling trees. 
This cut is plainly shown in Figure 17. 

The line has a fall of 4,100 feet, and transports ten tons per hour 
during all kinds of weather. The snow reaches a depth of sixteen feet 
at some places on the line. The system is operated in two sections, each 
of about two and one-quarter miles length. 

Figure 34 shows the large log bin at the upper end of this Ropeway 
into which the mine cars from several directions dump their ore. This 
view was taken before the structure was roofed in. In the lower part of 
this structure is the upper terminal of the Ropeway. 

Figure 35 illustrates the bins at the lower end of the line. Here the 
Ropeway passes over the bins to the terminal seen in the back-ground and 
dumps its load into whichever bin it is desired by setting the trip. 

Extract from article in Nelson, B. C, TribH7ie of August 7, 1897 • 

"The large copper furnace at the Hall Mines has been running 
smoothly since being blown in Saturday morning. During the first five 
days running, up to six o'clock Thursday morning, 2,250,020 pounds of 
Silver King ore were put through the furnace, producing 215,934 pounds 
of matte. 

' ' When the big furnace was started there was a good supply of ore 
in the bins ; as the Tramway is bringing down two hundred and ten tons 




32 

per da}', it is thought that a long and profitable run will be made. There 
is an ore reserve of 3,000 tons at the mine, and if pushed the Tramway 
can deliver two hundred and seventy-five tons everj^ twenty-four hours." 
Extract from the report of the directors of the Hall Mines, Limited^ 
British Columbia, for the year ending September 30, 1897 : 

" The wire Tramway has continued to give satisfaction, and in May 
advantage was taken of the opportunity afforded by the closing down of 
the blast furnace, pending a replenishment of the stock of ore in the ore 
bins at the mine, to renew the wire rope, and by the introduction of an 
improved clip strap, permanence and regularity in the working have been 
assured." 

Profile No. 3 illustrates the profile of the Ropeway over the famous 
Chilcoot Pass, Alaska, on the way to the Klondike gold fields. This will 
transport the luggage and supplies over the most difficult part of the 
journey. (See Fig. 39.) The south end is some fifteen or twenty miles 
from D3-ea, the country affording comparatively good traveling, and from 
the north end the journey is made largely by water through lakes and 
rivers. The Ropeway displaces some five to ten miles of tortuous and 
extremely rough trail, over a country covered with massive chunks of 
rock, dropped from surrounding peaks. In fact the trail is so rough that 
it is impassable for animals, and everything has to be packed over by men 





Fig. 40. 



causing a very serious delay in the trip, while now with a load of one 
hundred pounds on each bundle carrier, the Ropeway will deliver six tons 
per hour. Hence the enormous advantage of the Ropeway appears for 
this place. 

Summanzing briefly: — 

The foregoing system will work on any level or at any angle, and is 
applicable, among other purposes : 

For conveying ore from the mine to the mill. 

For conveying sugar cane from field to mill. 

For excavating quantities of earth, sand, etc. 

For the construction of dams, levees, embankments, etc. 

For conveying large quantities of any material for any considerable 
distance. 

For carrying off debris, slickens, tailings, etc. 

For transporting produce, lumber, shingles, shakes, fuel, nitre, coal, 
etc., across difficult points, and to and from shipping in an offing. 

For conveying passengers or materials across gorges, chasms, and 

over hazardous roads. 

For supplying water to reservoirs across chasms. 



34 

The advantages claimed are: 

No road grading nor building is required. 

It can work under all circumstances ot weather, with great depth of 
snow on the ground, during heav}' storms and freshets. 

It can run constantly without rest; as well during a dark night as on 
a clear day. 

It will work up hill or down hill. 

It can cross deep gorges and chasms. 

It can pass around precipitous bluffs and perpendicular cliffs or over 
the most rugged mountains. 

It can be applied to grading — either by filling the buckets in the 
ordinary way, or by using scrapers instead of buckets, on the rope, where 
the character of the soil will permit. 

It can furnish power, when the angle of descentexceedsone in seven, 
by the gravitation of the descending load of five tons per hour. It can 
transmit power by means of an engine attached to either end at the same 
time it is performing its other functions. 

It can be constructed and worked cheaper than an}- other system 
can be constructed and worked under like circumstances.

There being only one rope used, the working parts are reduced to a 
minimum. The carriers being fixed to the rope by means of a patent 
clip, the material transported can never be lost on the way. 

Please bear in mind that we have erected the Hallidie Ropeway dur- 
ing the past twenty-six years throughout the continent of the two 
Americas, under every conceivable circumstance, and have never made a 
failure. We have constructed lines with spans of 2,000 feet, and are pre- 
pared to erect this system in competition with any other. We append 
herewith some of the testimonials we have received, and shall be pleased 
to estimate on any proposed line. 

We will send a competent man to examine, survey and report on 
proposed Ropeways, and will furnish close estimates of cost. 

We contract for either supplying the material, or supplying material 
and superintending erection, or for the line complete and in running 
order. 

Our engineers are men of experience and understand the proper 
construction needed for peculiar conditions and locations. Mine owners 



36 

and others can thus avoid the mistakes liable to be made by those inex- 
perienced in this method of transportation. 

Our machinery is covered by U. S. lyetters patents No. 357664, 
422892, 466S80, 483442, 558666, 558645, 589654, 597904. 610353, 
624648 and 627258, and patents pending; and notice is hereby given 
that no unlicensed use of the inventions covered by these patents will be 
permitted. 

We solicit correspondence in regard to tramways or any mechanism 
pertaining to or in relation to wire rope. Our working model of a tiam- 
way and loader is on exhibition in our San Francisco and Seattle 
ofiBce, and can be seen working at any time. We also publish pamph- 
lets on the transportation of sugar cane and on excavation by wire rope. 
If you are interested in any of our lines, we will be pleased to cor- 
respond with you in relation to same.

Little Cottonwood, Utah. \ 



Superintendent's Office, Sept. 28, 1872. 
The Ropeway constructed by you (Haixidie's Patent) for the Emma Hill Con- 
solidated Mining Company has been built in a most substantial and workmanlike 
manner, and is at this time in splendid working condition. I most cheerfully accept 
the work for the Company, and recommend it to others wishing a sure and speedy 
transit for ores over places impracticable for wagon roads, etc. 

Respectfully, 

I. U. CoLBATH, Superintendent. 



Office of the Chicago Silver Mining Co. 

Salt Lake City, Dec. i, 1874. 

I have pleasure in stating that your Ropeway, put up at the Chicago Mine, Ophir 
District, Utah Territory, one year ago last summer, has been in constant use ever 
since, and with the most satisfactory results. 

The line, as you are aware, is constructed over an extremely rugged country, one 
and one-quarter miles in length. 

For the first half mile or so it is down a very steep mountain side, whence it 
passes over the brow of another one; thence it continues down Dry Canyon at an 
angle of fifteen to eighteen degrees. 

The structure is an entire success, the entire cost of which has moie than been 
saved already, although it has not been worked up to half its capacity. 

In the estimate of earnings no account was taken of supplies sent to the mine, 
including water, etc., by no means an inconsiderable item. 

Truly yours, 

W. S. GODBE, 

Manager Chicago S. M. Co. {^Limited). 



[From the Utah Mining Journal, Salt Lake, Sept. 2.3, 1872.] 

THE VALLEJO ROPEWAY. 
The Vallejo Tunnel Company's Tramway, in Little Cottonwood, built on the 
Hallidie'S Patented Plan, is a complete success. It is between 2,300 and 2,400 
feet in length, and is supported by thirteen stations. The fall in this distance is 
about 600 feet, and the wire rope, which is five-eighths of an inch in diameter, will 
safely and easily deliver 100 tons in six hours. The machinery is automatic, loading 
or unloading the sacks or buckets. The stations are aDout 200 feet apart, and the 
entire apparatus is strong and safe. As the wire rope is elevated about forty feet 
above the surface of the hill, the Tramway can be worked all winter long without the 
slightest trouble. 



Kernville, Kern County, Cal., May 6, 1878. 
Your Patent Wire Ropeway, which I recently erected at the Harley Mine, near 
this place, works entirely satisfactory, effecting a great saving in the cost of trans- 
porting ore from the mine to the mill, and in sending lumber and supplies to the 
mine. The cost of transporting the ore by pack-tram was five dollars per ton — by 
your Ropeway it does not exceed fifty cents. The length is one mile and a half, the 
upper end having an elevation of over 3,000 feet above the lower end. It crosses a 
deep canyon at a height of 300 feet from the surface of the ground, with a single span 
of 750 feet; and altogether the ground is among the roughest in the Sierra Nevadas. 

Respectfully yours, 

A. BlaTCHLY, M. E.

In answer to your inquiry about the " Wire Ropeway,' erected by my advice for 
the Blue Jacket Mining Company, Bull Run District, Elko County, Nev., I have 
pleasure in stating that under the following conditions it works surpassingly well, 
and transports the ore by its own weight, without other power, for nearly a mile, 
over a rough, descending grade of eleven degrees from the mine to the mill, at a cost 
of about twenty cents per ton, thereby saving at least two dollars per ton, compared 
with horses. Yours respectfully,

OflBce of the Joab Lawrence Company, I 
Chas. Read,Sec'y; Joab Lawrence, Pres. I 

Salt Lake City, Utah, December i, 1883. 

I have been familiar with the working of the Hallidie Wire Ropeway, con- 
structed eleven (11) years ago, on the then property of the Emma Hill Consolidated 
Mining Company, since it was built, and have had charge of the same the last 
seven (7) years. It has been in practically continuous use since 1872, and is now in 
operation almost every day, not only in the transportation of ore, but in carrying 
mining timbers, lumber, cordwood, coal — in fact, everything used in the mines. 

I can heartily recommend the Hallidie Wire Ropeway, because its action is 
simple, it is comparatively inexpensive, both in construction and operation, and is 
practically unlimited in capacity. Yours, etc., 

Chas. Read.

Office of the Standard Consolidated Mining Company. 

vSan Fr.vncisco, December 6, 1S83. 
la answer to your request, the Standard Consolidated Mining Companj' take 
great pleasure in certifying to the excellence of the Hai,i.idie Ropeway, which has 
been in almost continuous use by our company for the past seven j-ears. 

During said period your Ropeway has worked to our entire satisfaction, and by 
it we have transported many thousand tons of ore, etc., from the mine to the mill. 

That we are pleased with it is evidenced by the fact that we continue to use it, and, 
aside from some slight and immaterial modifications, your Ropeway is as it was in 
1876, when first erected. Truly yours, 

John H. Boyd, 
Pres. Standard Con. Mining Co. 

Kealia, Kauai, H. I., June 28, 1883. 
In answer to your inquiry concerning the Hai^i^idie Ropeway erected by you, 
and now in use on this plantation, for transporting cane from place of growth to the 
crushing mill, I take great pleasure in replying as follows : The line is about one 
and one-half miles in length, over a very rough country. It was first put in opera- 
tion in February, 18S2, and since which time it has been almost constantlj' in use, 
giving entire satisfaction, and proving itself to be the cheapest means of transporta- 
tion under like circumstances. The carrying capacity of the line is 240 tons in ten 
hours. The power required to move the line is taken from the cane engine shaft by 
employing the proper sized pulleys and belts. The line should be constructed of 
good material, and, if properly erected, will do its work satisfactorily at all times. 

Yours very truly, 

Wm. Blaisdell, Manager. 





Kealia, Kauai, H. I., June i6, 1S82. 
The HaIvIvIDIE Ropeway erected by you several months ago, on this planta- 
tion, is a perfect success, and gives entire satisfaction. When we are able to keep 
the line supplied with cane, it gives us 2,400 gallons of juice per hour. The line is 
one and one-quarter miles in length, over some very broken country. 

Power to run the Ropeway is taken from the cane engine by bolting on to the 
fly-wheel arms a 4-foot pulley, then with 40 feet of lo-inch belting over a 60-inch 
pulley on counter-shaft. The pinion shaft is then put in motion by 10 inch belting 
over 30-inch pulley on counter and 40-inch pulley on pinion shaft, which moves the 
Ropeway 187 feet per minute. 

With forty pounds of steam, on closing the throttle, without the Ropeway, the 
engine will make thirty revolutions before stopping; with the Ropeway attached, it 
will make twenty-six or twenty-seven revolutions — showing that but little power is 
reijuired to run it. The line has a fall of 135 feet in the whole distance. 

Respectfully yours, 

John Sherman, 

Chief Engineer. 



Paauhau, H. I., January 13, 1882. 
I hereby certify that Mr. Hallidie's Patent Wire Ropeway, which you 
have put up on the Paauhau Plantation for the purpose of delivering sugar-cane to 
this mill, has given entire satisfaction. 

It does fully the work it was represented to do, and delivers easily the quantity 
of cane stipulated in the contract directly into the cane-carrier. Yours truly, 

A. Otto, 
Manager Paauhau Mills, Hawaii.

W. A. Mercer, Manager. 

From San Juan Mining Co., Bahia Angeles, Lower California. 

Butte, Mont., May 6, 1893. 
Mr. a. S. Hallidie, Pres., San Francisco: 

Dear Sir: — As per enclosed receipt, I forward you to-day a photo of part of our 
tramway line in the "San Juan." 

This photo is interesting from the fact that it plainly shows the wire cable from 
the Lower Terminal up the mountain side to station 18, a distance of nearly two 
miles. Total length of line is two miles, i.Soo feet. From the last report of super- 
intendent at the mine, the tramway is doing splendidly. Fifty-two tons in 9>^ hours 
is, I think, the best work we have done so far, which is quite satisfactory, as you 
may well believe. 

With best wishes for the continued success of the Tram and its inventor, 

I am, yours very truly, 
(Signed) F. F. Cranz. 



Office of the Jackson and Lakeview Mining Company. 

LUNDY, Cal., April 16, 1894. 

Gentlemen: — The Hallidie Wire Ropeway, erected for this company in November, 
1891, under the supervision of your engineer, Mr. E. I. Parsons, has been in prac- 
tically continuous use since that time, and has been a success from the start. 

The line is over 2,400 feet in length; fitted with grip pulley and brake at either 
end, supported on fifteen intermediate stations ranging from ten to thirty-four feet 
in height, and running over a rugged country with a fall of practically one in two. 

We have delivered at the mill, using the Ropeway but few hours in the day, 
over 12,000 tons of ore, and shipping up to the mine hundreds of thousands of feet of 
lumber and timber, besides all other mining supplies; and all at a very low rate of 
cost; we ship lumber and timber of any length up to eighteen feet with ease and 
safety. 

The line has been well "kept up," and is now in good working order, at a cost for 
new parts, repairs, etc., since November, 1891, of less than five hundred dollars 
(I500). Yours truly, 

(Signed) R. T. Pierce, Superintendent. 

Plomosas, Sinaloa, Mex. 

Replying to yours concerning the Ropeway for transporting wood and charcoal, 
erected on this property some two and a half years since, would say as follows: The 
entire length of the same is about 9,000 feet, has three angles, supported by only ten 
structures in its entire length, with spans varj-ing from 400 to i,6co feet in length. 
The line is erected over some of the most rugged mountainous country in Mexico, 
and cost, complete and in running order, about 119,000. 

[Extract letter of April 15, 1886]: 

The cost of wood this year was |35,ooo, against 1152,000 j-ear before, without 
cable. The cost of $35,000 includes all repairs, etc., since erection. We are ahead 
of the mill 10,000 yards of wood, and , besides, we have brought down all the charcoal 
that has been burned in the past year and a half. The wood this year will cost 30 per 
cent, less than last year. B. McInTyre. 



4S 

[Extract letter of April 6, 1886] : 

As we have stated to you on former occasions, our " Ropeway " still continues to 
do its work well, and gives every satisfaction. I am informed that the transportation 
of the ore, including filling the buckets and repairs to Ropeway, has only cost ten 
cents per ton since erected, three years ago. 

E. W. Thompson, 
For Anglo-Mexican Mining and Land Co., 

Tapacoya, Sinaloa, Mex. 



[Extract of letter from Sir Joseph W. Trutch, Managing Director Hall Mines, 
Ivtd., Nelson, B. C, dated March 11, 1898] : 

"It gives me much pleasure to state that the Ropeway you built for us has been 
working most satisfactorily. * * * it has been carrying a good deal more than 
ten tons an hour and with hardly any interruption. * * * I can only say that as 
it has been working for the last year, the Hallidie system has done for us more than 
I expected of it." 

The above Ropeway is 23,797 feet long (4^ miles'), and in that distance has a fall 
of over 4,000 feet. It is constructed in two sections; the upper one 10,300 feet long, 
with a fall of 1,620 feet; is in the storm belt, where snow falls to a depth of twenty 
feet in places and the wind is very violent. The lower section is 13,500 feet long, 
with a fall of 2,400 feet. This is in a milder climate and relatively free from great 
depths of snow. 

During the year 1897 the Ropeway conveyed from the mines to the smelting 
works 49,540 tons of ore. 

The Company has decided to increase the capacity to 100, oco tons per annum, 
by increasing the size of the ore carriers, at a comparatively small outlay. 

The Report of the Directors to the Stockholders for the year ending September 
30, 1897, states that " The Wire Tramway has continued to give satisfaction." 



Office of the Wilmans Mining Co. 

Seattle, Wash., March 31, 1894. 
Gentlemen: — The Hallidie Patent Wire Rope Tramway furnished by you for use 
at our mines at Monte Cristo has, in every respect, proved entirely satisfactory to 
us. Our tramway is, I believe, on one of the steepest grades of any line in the United 
States, and though we have not yet tested it to its capacity, it has done sufficient 
work to warrant us in recommending it. Yours truly, 

(Signed) F. W. Wilmans, President and Manager.

Mr. S. J. Wilkins, representing the California Wire Works of San Francisco : 

I am very much pleased at the way the "tram " is working, and see no reason 
why it should give us the slightest trouble, and cannot but congratulate you on the ex- 
cellent job you have done for us, which was the harder from being in a foieign land, 
where your help, almost entirely, spoke ia a foreign language.

you furnished for the " Bella Vista Mining and Milling Company," and which was 
constructed by Mr. S.J. Wilkins of your city, in Costa Rica, Central America, has 
given entire satisfaction, and we are thoroughly pleased with it. It was finished in 
February of this year, and it has been running since that time. 

The line is 1,200 feet long, and delivers five tons of ore per hour with ease and 
econom}'. Yours very truly,

Jordan, Mono Co., Cal., Oct. 16, 1899. 
California Wire Works, 

No. 9 Fremont Street, San Francisco, Cal. : 
Gentlemen : — The Wire Ropeway purchased from you four years ago has given 
entire satisfaction. The automatic ore-loader, which was, I believe, the first erected 
under this patent, saves the labor of two men, or six dollars per day. One man now 
operates and breaks the tram, sending 60 tons of ore per day to mill, when required, 
with one-half the buckets on the line and fills the loader at same time. This capac- 
ity can be easily increased by adding the other buckets. No one is required at lower 
end of tram excepting when supplies are sent up. The cost of transportation of ore 
is five cents per ton. Yours truly, 

(Signed) H. W. Nelson, Superintendent. 



Extract from letter from R. G. Hart, owner Tex. Con. Mines & Mill, Hart, 
Shasta Co., Cal. : 

January 30, 1894. 
I have a Hallidie Transmission Ropeway, one mile long, to transport ore from 
mine to mill on Sacramento River. It cost me complete about six thousand dollars 
(16,000), and we transport fifty tons quartz in ten hours ; rope 3^ inch diameter steel 
wire. Could transport much more by putting on more buckets. 

I have used it continuously for three years, and am using it now every daj^and 
can recommend it to any one wanting cheap transportation. It cost me |;i.ooper 
ton to haul with teams. Now it costs I9;'4 cents per ton, counting wear and tear for 
three years to January i, 1894. 

I have no doubt about the Hallidie Ropeway transporting blocks or cordwood 
at a nominal cost. The roughness of country cuts a small figure. 

Very truly yours, 
(Signed) R. G. Hart, Sr.
