AM. PHOTO-L1TH'O.CO.N.Y(OSBORNES PROCESS) UXITED STATES PATENT OFFICE. SAMUEL B. BRL'SSTAR. OF KENSINGTON 7 , PENNSYLVANIA. MACHINE FOR. MAKING BRICKS. 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 them. 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 693 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 described. 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. The invention claimed and desired to be secured by Letters Patent in the before described machine for making bricks con- sists, in — ■ 75 The wheels and plows for tempering the clay — the traveling hopper and discharging wheels for spreading the clay evenly in the tempering trough— the shear for turning the clay from the tempering into the mold- 80 ing trough — the shear and striker for strik- ing the brick and turning the surplus clay back into the tempering trough— the sand- ing apparatus— the arrangement of the slid- ing molds and the chambers into which they 85 are inserted under the molding trough — the spaces formed under the tempering trough through which any accumulated clay may be discharged into the horse walk — also the discharging boxes — the whole in 90 combination as before described.
