IMPROVE!) MACHINE FOR RE-PRESSING BRICKS The Schedule referred to in these Lettera Patent and making part of the same,

To all whom it may concern Be it known that I, HENRY MAURER, of New York, in the county and State ot' New York, have invented new and useful Improvements in Machines t'or lie-Pressing Bricks; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters oi' reference marked thereon.

Figure I represents a top view or plan of my iinproved machine;

Figure l'I is a longitudinal section of the same; and

Figure 1H is a cross-section atlinc V VI in Fig: I1.

Similar letters represent similar parts.

The nature of my invention consists inthe arrangement of suitable escape-openings in the mould-box, wherein the formed bricks are ris-pressed, for thepurpose of receiving any ot' the surplus material which may be in the original or first-made blick, insuring thereby the regularity of the bricks when the same are re-pressed.

In the accompanying drawings- A represents the framing oi' the machine, the front and back of nhich are strengthened and securely fastened together, by bolts a a, situated in the line with the centre of the mould-box B.

This mould-box is arranged near the middle, in the flaming A, and into which a piston or platen, C, is fitted, supported and guided on the bolts a, a.

Another' pistou or platen, D, likewise guided on the bolts a, a, is arranged to enter the front ofthe mouldbox B.

This platen D is connected to a toggle-joint, E, operated by a cam, F, placed on the revolving slndt S, whereby this platen D is moved into the mould-box B, to act upon the brick to be rie-pressed.

A spring, b, acting upon one ot' the levers forming the toggle-joint E, will causo said joint to be moved or pressed downwards, for the purpose ol'drawing the platen D ont oi1 the mould-box l, after the brick has received the desired amount ot` pressure, and when the toggle-joint is relieved t'roln the action of the cam F.

As soon as the platen l) is withdrawn out oi' the mould-box l5, n projection, n, on a cam, l, on the shaft S, comes in contact with n, projection, 2, on the level' H, which latter is connected, through the lever J, with the pinten U, in suoli a manner as to move said platen C further into the mould-box ll, and thus push the pressed brick out otA said mould-box upon :L block or table, l, situated iu the l'ront otsziid mouldbox.

\Vhcn the pressed brick has been moved upon the block li, the cani L on the shat't S operates the lover M, connected with the guide-rod P of the block K,

and moves thereby this block K, with the pressed brick, upward in a line with the top face ofthe frame A.

On the top of the frame A, above the block K, a slide, N, is arranged, with au open slot on its forward end, and an opening, d, capable of receiving and passing through ita common brick.

This slide is connected, through the lever 0, with a lever, Q, which latter is provided with a projection, m, working against the face of an eccentric disk, R, (see Fig. 1,) fast on the end of the shaft S, and through which motion is communicated to said slide N, as soon as the block K has been moved on a line with the top of the frame, whereby the-pressed brick is removed from the top of the block K, and the unpresscd brick, previously placed into the opening d, in the slide N, is left upon the top of said block.

The block K is then moved downward, so as to bring` the impressed brick opposite the opening in the mould-box B, when the toggle-joint E is acted upon bythe cam F, causing thereby the platen 1) to be moved toward and into the mould-box B, whereby the unpressed brick is moved from the top of the block K, pushed into the mould-box, and then receives there the desired amount ot' pressure.

Through the sides of the mould-box B openings :n are made, (only two are shown in the drawings, through the top,) into which pistons n are fitted, acted upon by powerful springs e.

\Vhile the bricks are re-pressed in the mouldbox B, any excess of material which may be in the brick, as tirst moulded, will escape into these openings, by pushing back the pistons n in the same, and prevent thereby any dissi-rangement or breakage of' the machinery, at the same time insuring the regularity of the bricks.

When the platen O is operated so as to push the pressed brick ont ot' the mould, the springs o acting upon thc pistons n in the holes x, will force this material ont of the holes again, after the platen C has passed the holes, and the material thus thrown into the mould-box will be cleared out of the same by the backward motion of the platen C.

I (ind that in practice, two holes through the top ol' the mould-box, as represented in the drawings, are sufiicientin most cases; but any number, similarly arranged, may be made in the sides and bottom, as may be found necessary and desired.

The block or table K is made hollow, so as to forni a cavity, w, to receive oil or any other lubricatingsubst-ance.

This cavity is connected by suitable holes, with pieces of cloth, sponge, or its equivalent 3 3, arranged on each side ot the block E, which comes in contact with the faces ot' the platen D and C during the upward and downward motion of said block K, and oil or grease thereby these faces, after euch operation of conjunction with the solid plungers (i D, in the inunre-pressing a brick. ner und for the purpose herein set iol-th.
