SPECIFICATION forming part of Reissued Letters Patent No. 10,524-, dated September 23, 1884.

Application for reissue filed May 21, 1884.

To all whom it may concern):

Be it known that I, ROBERT N. Rossa citizen of the United States, residing at St. Louis, in the countyfof St. Louis and Stater of Missouri, have invented certain new and useful Improvements in Brick-Machines, of which the following is a specification, reference be, ing had therein to the accompanying drawings, in which- Figure 1 is part inside elevation and part in vertical section. Fig. 2 is a front end view. Fig. 3 is a vertical section showing the parts in a different position from that shown in Fig. 1. Fig. 4 is a top view. Fig. 5 is a rear end view. Fig. 6 is a perspective view of the charger. lower plunger, and Fig. S is asimilar view of one of the removable plates which form the faces of the dies of the lower plunger.

My invention relates to that class of brick.` machines wherein opposing plungers ap- Vpreaching each other press the clay in the molds; and my invention consists in points of novelty hereinafter fully described and claimed. v i

Referring to the drawings, A represents the Outer casing or housing of the machine, and B the driving-pulley, rigidly secured to the shaft B', journaled in boxes B2, secured to a swinging frame, C, supported on a bolt or rod, C, having bearing at one end in one side of they housing A, and at the other end in a side plate, D, supported by the base D of the machine.

On the shaft-B', between the boxes B2, and rigidly secured thereto, is a friction drivingroller, E, (see Fig. 1,) which bears against and turns a roller 0r wheel, F', on a countershaft, F, journaled in suitable boxes, F2, secured to the side plate, D, and to the housing A. (See Figs. 1, 2, 4, and.) The lfrictionroller E can be thrown out of or in contact with the roller F by means of a lever, G, fulcrumed in a frame, G', (see Fig. 1,) and connected at its lower end by means of a rod, H, with the lower end of an arm, I, pivoted to lugs I of the housing, and connected by its other end to the lower end'of the swinging Fig. 7 is a perspective view of the frame C, the connection being made by means of a pin, C4, in the frame entering slots I2 of 5o the arm. Thusjit will be seen that byl operating the lever the friction-wheels can be brought into and thrown out of engagement. The lever is held to its adjustment by a catchbar, I3, engaging with the frame by means of 5 5 notches, as shown in Fig. 1.

On the shaft F, and rigidly secured thereto,

is a pinion, J, which meshes into two cogwheels, K L, the former being on a shaft, K,

working in journal-boxes K2, (see Fig. 5,) andv 6o the latter being on a shaft, L', journaled in boxes L2. (See Figs. 1 and 5.)

Connected to one of the spokes or arms of the wheel K is an arm, M, the connection being made by a pin, K3, in the spoke entering a slot, M, in the end of the arm. (See Figs. 1 and 3.) The other end of the arm M is connected to a block, N, rocking on a shaft, O, supported by the housing A. (See Figs. Vl, 2,

and 3.) The rock-block N is also connected 7o` to the upper plunger, Q, by a link, P, (see Figs. 2 and 3,) and thus it will be seen that as the wheel K is turned this plunger will be rst raised, as shown inFig. l, and then compressed, as shown in Fig. 3, and as the pin K3 75 works in a slot of the arm, there will be alost motion at each revolution of the wheel, allowv ing the plunger to remain at rest at short in` tervals each time it is raised, allowing time for the bricks to be removed and the molds 8o connected to the lower plunger, S, the connecting-ar'm being ,lettered S', the rocking block S2, its supporting-shaft S3, and the link connecting the block with the plunger Si, through 9o which the connecting-bolt passes, the object being to allow the plunger to be raised after the rocking block has done` its work by means of a lever-arm, U, fulcrumed on a shaft, U,

supported by the housing of the machine and 95 aside plate, A4. (See Figs. 2, 4 and 5.)- The that the wheel Kis con-` o Y- When the charger has Vthus been forced forforward end of the arm U' engages with Vthe plunger. The other end is operated on by a pin, V', of a wheel, V, on the shaft V", journaled in boxes V3, secured to the housing.. The wheel V is engaged vand driven by a pinion, V4, on the counter-shaft F. (See Figs. 4 and 5.) rlhus, when the block S2 has raised the plunger, as shown in Fig. 3, completing its work, the arm U' is operated, as described, carrying the lower l plunger up as the upper plunger makes its upward movement, the bricks of course being carried up between them, the lower plunger rising to the top of the mold, and thus neither plunger is pulled .away from the brick while inthe mold, so as to cause a strong suction, which is liable to injure the brick. This I considera matter of great practical importance, not 'only from the fact that a separation of the upper plunger from the brick would exert upon it a suction tending to impair its integrity, but also because the strong vacuum created behind the plunger would require a great waste of power to overcome it. VVhenthe lower plunger has been raised to the necessary height to carry the brick clear of the mold, the pin V of the wheel Vpasses onto a portion of the lever U', so curved as to allow said lower plungerto remain temporarily stationary, while the upper plunger continues its .ascent slightly in order to separate from the brick. While the two plungers are thus temporarily sustained the charger W makes a forward movement, (see,

Figs. l and 3,) shoving the bricks that have just been raised from the molds onto arest, Y. At this moment the'pin V of the wheel V slips off the lever U', and consequentlythe lower plunger drops, vand the charge of vclay in the charger drops into kthe molds, after which the charger makes a quick backward movement to get out of the way of the upper plunger as it makes its descent. The charger is forced forward by arms W', to which it is connected l by a pin, W2, working in slots W3 of the arms.

The arms are rigidly secured to the rock-shaft II, (upon which the lever U' is loosely ful- I crumed,) and have rearwardly-extended ends W4, which are operated on by cams L4 and V5 striking them from beneath, these cams being secured, respectively, to the shafts L' and V2.

ward and charges the molds,it receives a'quick backward movement (as soon as the cams leave the arms) by an adjustable counter-balance, W5, on an arm or lever, IV, rigidly secured to the shaft U. (See Figs. 1, 2, 4, and 5.)

W7 (seeFig. 2) is a cushionedfpost to receive the counter-balance and stop its descent, when the charger has been moved back, until its receptacles are under the hopper W8, which holds the clay for iilling the charger. (See Fig. 3.) Vhen thepharger again moves forward to remove bricks lfrom the lower plunger, it forces them against those previously deposited on the rest, driving them onto an endless-belt, l, which carries them away, and so Vsprocket-wheels, 4 5.

on.` The belt is driven by a shaft, 2, journaled in the frame and turned by a chain, 3, connecting it with the shaft F by suitable (See Figs. 4 and 5.) My machine is designed to make two bricks at a time, so there is a pair of molds, and each plunger has arpair of dies, (see Fig. 7,) and l the charger a pair of receiving-receptacles. (See Fig. 6.) The holes S6 in the lower plunger (see Fig. 7)`are to receive the forked end of the lever U'.

In order to make different thicknesses of l brick and have a uniform pressure on all, I provide the lower plunger-dies with removable plates ST (see Figs. 7 and 8)\of different thicknesses. f

6 represents strengthening rods or ties connecting the upper part of the machine with the base. (See Figs. Zand 5.)
