QPECIPICAI'ION forming part of Letters Patent NO. 296,305, dated April 8, 1884.-

Application filed February 20, 1884. (No model.)

To a, wit-m it may concern:

Be it known that I, JOHN BAILLIE, of Salem, in the county of Golumbiana and State of Ohio, have invented a certain new and Improved Brick-Maghine; and I do hereby declare that the following is a full and complete description thereof.

The construction and operation of the brickmachine above alluded to are substantially as follows,the description being i ll ustratedby the annexed drawings, making a part of this'specification, in which- Figure 1 represents a side elevation of the machine. Fig. 2 is an end elevation. I Fig. 3 is a plan view. Fig. 4 is a transverse section through the line a: m. Fig. 5 is a longitudinal section. Figs. 6, I, S, and 9 are detached sections.

Like letters of reference denote like parts in the drawings. I

' In and upon a suitably-constructed frame, of which" A. is the top, is'arranged the following-described mechanism: On two opposite sides of the top of the frame are secured two pairs of standards, B B and G 0, Figs. 1 and 2, connected to each other, respectively,by the rods 1) and E. Between the said standards is a clamping case or box consisting of a verticallymovable top, F, and laterally movable ends G and H, Figs. 1 and 3. A reciprocal vertical action is obtained to the top of the case by means of the following device:

I is a cross head or beam, to which the said top is secured by acentral bolt, a, and side bolts, 2) b, Fig. i. The lower ends of the side bolts descend through the top of the frame A in bosses, as shown in Fig. 4, in which they are closely fitted but free to move, and are guided thereby in their reciprocal vertical movement, actuated by the eccentrics 1 and 2, to the rings J J of which they are connected, as seen at c in Fig. 4.

It will be obvious that when the shaft K, on which the eccentrics are secured, is operated by the lever L the cross-head will be given a reciprocal vertical movement, and therewith the top of the case. The ends of the clamping box or case are operated laterally at the same time by means of a block, M, Fig. i, fitted movably between the sides or wings N of the ends G and H of the case, as shown in said Fig. 4.

in the detached views, Fig. 9.

The standard 0 is removed, that one of the sides or wings of the end G may be seen. A top view of the end G or" the case, with the block between the wings thereof, is shown in Fig. 9. On each side of said block is an in clined rib, (1, adapted to fit in a correspond ing groove in the sides of the wings N, as seen The block or blocks M M are connected to the. ends of the cross head or beam I by the screw-bolts O 0, respectively, and by which the blocks are given a vertical movement as the cross-head I is operated, and whereby at the same time the blocks have a lateral movement, produced by the inclined ribs working in the corresponding grooves, which, when the blocks move upward with the cross-head, the inclined ribs move the ends of the case outward, and, per contra, when the cross-head moves downward the inclined ribs force the ends inward, for a purpose presently shown.

The rear side of the clamping-ease consists of a sliding carriage composed of a bed-plate, P, Fig. 3,'fitted in the opening Q in the top A of the machine, and supported therein upon rabbets c, on which the carriage slides longitudinally. On said bed-plate l? are two standing plates, 3 and 4. The plate 4B is fixed to the bed-plate P, whereas the plate 3 is movable toward and away from the fixed plate 4:. The movable plate is attached to the bed-plate by means of a neck, 1%, Fig. 8, )rojectingdownward from said plate through a slot, S, in the bed-plate, and is secured in its connection therewith by a rabbet in the sides of the neck, adapted to engage corresponding rabbets in the under sides of the edges of the slot, substantially as shown in said Fig. 8.

The object in obtaining to the plate 3 a movable condition will hereinafter be made mani fest.

To the movable plate 3 is attached a handle, T, for moving the said plate, and also for moving the carriage, of which the plate forms a part, as above said.

U, Figs. 1 and 2, is a bar rigidly connected to the movable plate 3 of the carriage. Said bar extends back from the plate to a bloclr,V, in which it is fitted closely in a groove therein, and guided in itslongitudinal reciprocal movements for moving the carriage. The end of the bar U is continued down in the groove of the block V by a slide, f, and by which the length of the stroke of the bar may be lengthened or shortened, as may be required, for a purpose presently shown.' In the said slide f is pivoted an angular'lever or pawl, W, the lower end of which is heavier than the upper end or arm, that it may outbalance the upper arm, and thereby tend to keep it in the upright position shown in Fig. 5. The lower end of the lever is adapted to engage the shoulder formed on the end of the bar, as seen in Fig. 5. v

To the upper end of the angular lever above alluded to are connected the rods y, which extend therefrom forward and under the cross head or beam I and terminate in a single fiattened end, A, Fig. 3, suspended in a horizontal position by a link, B, depending from an arm, 0, secured to and projecting from the beam 1, as shown in the drawings. As above said, the standing plate 4 of the sliding carriage forms the rear side of the clamping box or case above alluded to. The front side of the case consists of the panel 1) of a boxlike slide, E, Figs. 1, 3, and 5, fitted to move in rabbet ways or guides F. Said slide E is operated by eccentrics G G on the shaft H, having its bearings in the standards 1, connected by the brace-rods J to the standards K. The eccentrics alluded to are connected to the slide E by a link L, Fig. 5, secured to the eccentrics by straps M M, and attached to the slide by a hinge-joint, as seen at N in Fig. 5, or by any other suitable j ointconnection. The eccentrics are operated for actuating the slide E by the lever O, secured to the shaft of the eccentrics.

1?, Figs. 1 and 3, is a shaft having its bearings in the standards K and Q. Close to and on each side of the standard Q, is a link, R. The two links are connected to each other by a bar, h, which passes through the standard in a slot, i, Figs. 6 and 7. The opposite ends of the two links R are connectedtoa push'plate, j, Fig. 1, having a vertical slot therein in alignment with the plate 4, so that on moving the push-platej in the transverse direction of the machine it will pass over the plate 4 without interfering therewith.

For operating the push-plate is the purpose of the shaft P, referred to, and which is connected to the bar 71 by means of the arms m m and links a a, substantially as shown in Figs. 3, 6, and 7, which are conjointly operated by the lever S, for actuating the push-plate as aforesaid.

Having described the construction and arrangement of the several devices constituting the machine, the practical operation of the same is as follows:

The machine, as above remarked, is for pressing brick. To this end the bricks are first molded in forms or molds in the usual way. lVhile such bricks are in a soft condition,

on before the plates 3 and 4, when the carriage is in the position shown in Fig. 3. The bricks are then pushed between the plates, as indicated by the dotted lines. It will be observed that the space between the plates 3 and4 is wider than the thickness of a brick, and that the distance from the plate 4 to the edge of the bed-plate is also wider than the thickness of the brick by so much as the thickness of the side D of the slide F at the front of the machine. The carriage containing the bricks is now moved forward into the case under the beam I by pulling upon the handle T. Before the body of the carriage moves, the first pull upon the handle draws the plate 3 forward to a stop, which is just far enough to clamp the sides of the brick a between the two plates 3 and 4. A continual pull upon the handle carries the carriage with the bricks into the case,

as above stated. During this forward movement of the carriage to the case the lever O is in a vertical position, as seen in Fig. 1. This position of the lever has pushed back the rods Y Y by impinging upon the end A thereof, so that the pawl V is lifted above the bar U, as indicated by the dotted lines a in Fig. 1. The carriage and bricks thus moved into the open case are shown in Fig. 5, in which n a are the bricks. The bricks thus in place, the top F and the ends of the case are now to be closed for holding the bricks in their normal shape while being pressed. This closing up of the case is done by turning the lever L down in the direction of the arrows, which, by actuating the eccentrics l and 2 and thebloeks M, above described, closes the said top and ends close upon themselves, thereby inclosing the bricks within, so that when the pressure is applied to them they will retain their proper shape and prevent leakage of the material. The pressure upon the bricks is now applied to them by the eccentrics G, and, on turning down the lever O, the eccentrics force the slide E into the case, thereby pressing the bricks into a more solid and shapely form than when taken from the mold.

That the carriage containing the bricks while under pressure may not recede in consequence of such applied pressure is the purpose of the pawl XV, and, as the lever 0 begins to move from its vertical position, the connecting-rods Y Y, held back by the said lever,will now move forward by means of the link B,which, invirtue of gravity, swings to a vertical position when the lever is moved away from the end A. This movement of the rods brings the pawl down upon the end of the bar U, as seen in Fig. 5. The end of the pawl, being lodged against the shoulder g of the bar, serves for an abutment for the bar, against which to resist the force of the eccentrics applied to the bricks.

The bricks, when pressed as above described, are then taken out as follows: A reversement of the movements above described of the machine will bring the carriage with the pressed bricks to its original position. (Shown in Fig.

the brick between the two plates, so that it can- 3.) On pushing back the carriage to said position the movable plate 3 will,as a consequence, be pushed back to the check 0, therebyreleasi'ng be easily pushed out, together with the brick on the opposite side of the plate ihwhich is free from confinement. This pushing out the bricks is done by the pressplate j and its operative mechanism above described, and on turning the lever S in the proper direction, the plate j will push the two bricks out onto the table m, on which they were first placed, and from which they are removed to be replaced'by others for being operated on, as above described.
