Specification of Letters Patent No. 693, dated April 14, 1838. 

To all whom it may: concern : 

Be it known that I. Samuel B. Brusstae, 
of the Kensington district, of the Northern 
Liberties. Philadelphia comity, State of 
5 Pennsylvania-, have invented a new and use- 
ful machine for making bricks, called 
"Brusstar's self-feeding, revolving, trun- 
dling, shearing, sanding, and brick pressing 
and "clay tempering machine," which is de- 

10 'scribed "as follows, reference being had. to 
the annexed drawings of the same making 
part of this specification. 

This machine consists of a post A, 
Figure 1, planted in the ground of sufficient 

15 strength ' for the purposes hereafter men- 
tioned. Around this post is constructed a 
circular foundation B of timber or stone 
about four feet wide and one foot deep, the 
diameter of the inner circle being about 

20 twentv-two feet, within which is formed a 
horse "track C of about twenty feet diameter. 
Upon this foundation are laid pieces of 
timber or sleepers, each about 18 inches long, 
1 inch wide, and 2f of an inch deep, set 

25 edgewise, with their inner ends flush with 
the inner circle and about 7 or 8 inches 
apart, radiating from the center of the cir- 
cle. Upon these pieces of timber is formed 
a circular trough D 18 inches wide and 

30 about 3 inches "deep. The sides of this 
trough consist of circular rails set upon the 
before mentioned timbers. In this trough 
the clav is tempered and is therefore called 
the tempering trough. The outer ends of 

35 the sleepers or the ends fartherest from the 
center of the circle serve as stops for the 
mold. The spaces 111 between them 
answer for the discharge of accumulated 
clay into the center. Outside of the temper- 

40 ing trough is another circular trough E 
about 10 "inches wide and 2f inches deep 
under which the molding is performed; this 
is called the molding trough. Under this 
trough are placed on edge wedge shaped 

45 pieces or partitions about 20 inches apart 
forming chambers for the molds. In the 
molding trough is thrown the clay for 
making the bricks. 

The molds F, Figs. 1 and 3, are made of 

60 metal containing each four apartments for 
four bricks having a handle on one side by 
which it is drawn out from and pushed into 
the chambers, under the molding trough 
through spaces formed in the rail, forming 

55 the outer edge of the trough. Only three 
are drawn. The molding trough all around 

is furnished with similarly constructed 
molds. : 

Over the circular foundation and base 
Avalk is erected a circular platform (j, Fig. 1, go 
upon posts about ten feet high, framed of 
suitable timber and covered with thick 
plank. On this platform is deposited the 
clay for the bricks, hauled up an inclined 
plane by horses or otherwise. The upper g 5 
ends of the posts may project above , the 
platform to form a railing. The center post 
acts as a support for the center of the plat- 
form. In the platform are two oblong open- 
ings H in which are constructed boxes I to 70 
receive the clay, made flaring downward and 
projecting below the platform a sufficient 
distance; the bottom of each moving on 
pivots J by means of levers K for discharg- 
ing the clay. Around the post is put a loose 75 
collar L flanged at its lower end, to which 
are fastened four or more arms M radiating 
from the center, having on the outer end of 
each a wheel 1ST about o feet diameter, and 
1 foot thick, weighing above 4 or 500 80 
pounds. Three of these wheels revolve in 
the inner or tempering trough for temper- 
ing the clay. The fourth wheel N revolves 
in the outer or molding trough for molding 
and pressing the bricks having flanges / to 85 
turn on the -rails P to prevent its pressing 
upon the edges of the molds so as to destroy 

In front of one of the wheels of the 
inner trough is a -fifth or smaller wheel Q, 90 
which acts as a regulator and feeder. See 
Figs. 1 and 3. Over and around these two 
wheels is constructed a traveling hopper 
E to receive the clay from the discharging 
boxes I. To a suitable framing on the arms 95 
and between the several wheels are attached 
plows S placed in the inner trough for 
turning the clay to the center thereof to 
be pressed or acted upon by the tempering 
wheels N in moving over it. Over the 100 
inner trough and attached to the before 
described frame is a shear T, Figs. 1 and 4, 
for throwing the clay into the outer 
trough — to be let down or raised by means 
of a lever U, cord e, and pulley p or other- 105 
wise. The forward end is made of a tri- 
angular shape so as to throw the clay to 
the left. Over the outer trough and" at- 
tached to said frame is a strike shear V 
Figs. 1 and 5 to strike the brick and throw 110 
back the surplus clay into the tempering 
trough; it is let down or raised by means 


of a lever W, cord d and pulley, and is 
made of a triangular shape for throwing 
the clay to the right. 

To the upper end of the collar is f as- 
5 tened a receiver X Figs. 1 and 6 for sand 
having an inclined bottom Y and trough 
2 for conducting the sand to the molds — 
the lower and outer end of which is cov- 
ered with a sieve, a to arrest the larger 

10 particles of the sand. 

The horses for operating the machine are 
attached to the arms and travel around in 
the horse track. 
Under the molds is a false bottom Fig. 

15 7 for keeping the molds up even with the 
tops of the partitions; it is made of a 
wedge shape on the under side in order to 
force the molds up even with the bottom 
of the molding trough. 

2-0 Behind the wheels are scrapers s, Fig. 1. 
fastened to the frame for keeping the 
wheels clean. 

Operation : The clay is hauled up and 
deposited upon the circular platform Gr. 

25 It is then thrown into the boxes I with 
movable bottoms; the bottom of the box 
over the feeding wheels is turned by the 
levers K attached to it which empties the 
clay into the traveling hopper from whence 

30 it passes between, the wheels N", Q, into the 
tempering trough D in an even layer oven 
which the hind wheel turns and flattens 
it out— as the horses move around with the 
wheels N; it is then met by one of the 

35 double plows S which turns it to the cen- 
ter. The next wheel then passes over it 
and again flattens it, the plow behind this 
wheel again turns it to the center of the 
ti-ough and so on until it be sufficiently 

40 tempered. The shear T for throwing the 
clay to the left is then let down by means 
of the cord, pulley, and weight, into the 
tempering' trough and from its triangu- 
lar shape and forward movement turns the 

45 clay over into the molding trough E. From 
this trough it is pressed into the molds by 
the pressing wheel 1ST revolving in said 
trough— the molds having previously been 

inserted into the chambers to which they 
belong. The shear and striker V is then 50 
let down into the molding trough, which, 
as it moves forward strikes the brick and 
turns the surplus clay again into the- tem- 
pering trough D. The molds are then 
drawn out from the chambers, the bricks 55 
off-borne, and the empty molds replaced. 

When the shear and striker are not in 
use they are raised from the troughs and 
secured by placing the levers against pins 
3 or stops in the frame. 60 

The sanding of the molds is performed 
by means of the inclined tube Z and screen 
a before described Figs. 1 and 6. 

On the arrival of the 'traveling hopper 
E beneath the other discharging box I the 65 
same operation takes place as that before 

The near half of the circular platform 
is omitted to be represented in the drawing 
in order to show the arrangement of the 70 
several parts of the machine.

secured by Letters Patent in the before 
described machine for making bricks con- 
sists, in — ■ 75
