SPECIFICATION forming part of Letters Patent No. 312,066, dated February 10, 1885.

Application filed November 4, 1884. (N model.)

To aZZ whom it may concern.-

Be it known that I, HARRY L. BALSON, of

' De Soto, in the county of Jefferson and State tion taken on line 3 3, Fig. 2. Fig. 4.is a vertical section taken on line 4 4, Fig. 2. Fig. 5 is a vertical section taken on the same line as Fig. 4, but showing the parts in different positions. Fig. 6 is a horizontal section taken on line 6 6, Fig. 4, and Fig. 7 is a similar view taken on line 7 7, Fig. 5.

My invention relates to an improved machine for making bricks; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the frame of the machine, having a table, A, in which is located the mold or molds A".

B represents an upper and Q a lower plungen D represents the main drive -shaft, journalled in boxes D, and operated by a cog wheel, D thereon engaged by a pinion, D, on a counter-shaft, D, having a pulley, D. The counter-shaft is journaled in boxes D secured to suitable supports, and it preferably has a pinion, D, on each end to engage the cog-wheels on the main shaft-one on each end. The main shaft may, however, be driven by any other suitable means. The upper plunger is connected by a link, I, to a crank, J, on a rock-shaft, J, journaled in the upper part of the frame. On the outer ends of the rock-shaft are cranks L, connectedby links L to sliding blocks L held to the sides of the frame A by strips A, or by other suitable means. On the lower ends of the blocks are friction-rollers L, that bear against cams M on the main shaft D. i As the shaft turns the blocks are raised from the position shown in Fig. 3 to the position shown in Fig. 1, which causes the plunger B to be forced from the position shown in Fig. 5 to the positionshown in Fig. 4, and as the shaft continues to turn the cams M leave the blocks, which fall, causing the plunger to move back to its upper position. As the upper plunger is lowered the lower plunger is raised by a cam, N, on the main shaft, and thus the bricks are pressed between them. The pressing movement of the lower plunger is caused by the part or face N of the cam, so that when the parts are in the position shown in Fig. 4 the pressing is done, and just at this point the upper plunger commences to recede or rise, and the lower plunger is made to follow it, to eject the bricks, by the part or face N 2 of the cam, and then when the cam leaves the plunger it falls to its lower position; but the plunger is held in its upper position a short time by the part or face N of the cam. This is done to give the charger time to shove the brick from over the mold.

0 represents the charger sliding on the table A, to the rear end of which is connected the upper end of a lever, P, fulcrumed at P to the frame A. The lower end of the lever is connected by a link, P to an arm, T, on a rock-shaft, T, to which is also secured two short levers, U and V. On the main shaft is a disk, \V, with a pin, W, on each side, one of which comes against the lever U to raise it, as shown by the arrow in'Fig. 4, which advances the charger to the position shown in Fig. 5. As the shaft continues to revolve the other pin comes against the upper edge of thelever V, and by depressing it'tnrns the rockshaft back, causing the charger to recede. The under edge of the lever U is so shaped that the pin, coming in contact with it, will cause it to be raised. The plunger 0 has a frictionroller, 0, to receive the cam N. The frame has flanges A to guide the plungers and hold them in place.

X represents a hopper located so as to be over the charger when it is in its normal position.

I claim as my invention-- 1. In a brick -machine, the mold A and upper plunger, B, in combination with the main shaft D, cam M, carried thereby, sliding block L upon the lower end of which said 100 cam impinges, rock-shaft J, having cranks L W, secured to said shaft, and having pins W and J, links L and I, connecting said cranks projecting from opposite sides, the rock-shaft with the sliding block L 'and plunger B, re- '1, having arms U and V, against the under spectively, the lower plunger, 0, and the cam and upper faces of which said pins engage, I 5 5 N, arranged on said shaft D in such position 1 respectively, the charger O, and levers conrelatively to the cam M as to commence its ac- I necting said charger with the rock-shaft T, as

t-ion immediately before the action of the latdescribed. ter ceases, as and for the purpose set forth.

2. In combination, the mold, the plungers 10 B C, the main shaft D, actuating the said plungers, substantially as described, the disk HARRY L. BALSON. In presence of- GEo. H. KNIGHT,
