IMPROVEMENT IN BRICK-MACHINES.

Specication forming part of Letters Patent No. 118,777, dated September 12, 1871.

To all whom it may concern:

Be it known that I, ALBAN ANDERSON, of Peekskill, county of 'Vestchester, State of New York, have invented certain Improvements in Repressing Brick-Machines, of which the following is a specification:

The object of this invention is to furnish a machine for making fine front brick that shall be positive in all its movements, simplein construction, yet strong and durable, and in which all sliding parts may be moved by the operating lever, leaving nothing to be put in place by hand.

Figure 1 is a sectional elevation of the machine. Fig. 2 is a side elevation of the same.

In the annexed drawing, A A, Fig. 1, represents one of two iron side pieces, secured to or being a part ofthe base piece B, which is mounted on rollers. More commonly a wooden frame is substituted for the iron base B. This side piece is connected with a corresponding one opposite by transverse blocks b b, the inner sides of which blocks and side pieces or uprights form the walls ofthe mold (l. These walls are furnished with a metallic lining, consisting of plates al a., which l construct, preferabl y, of steel, said plates being secured to the blocks b b and side pieces A A by rivets or otherwise. In constructing this mold the side pieces are planed out between the elevated ribs c c. The entire length and breadth of this space is then covered with sheet-steel, allowing the ribs to project above it sufliciently to give outer support to the transverse blocks b I), which are accurately planed and faced with steel, so that when the block is put in place a sharp, true, and durable corner is formed in the mold. The two blocks are held in place and the side pieces securely against them by bolts d d l d passing through the side pieces and recesses in the backs of the blocks. (See Figs. 1 and 2.) As the mold wears the size can be reduced by placing strips of thin metal between the higher parts of the blocks I; b and their supportingribs c c. The mold is provided with a plunger, D, which is rigidly secured to slides e e, which move in accurately-planed guides ff, which form a part of the side pieces A A. To the plunger is pivoted the pronged arm E, which is operated by the cam F. In the lower part of the side pieces A A, Fig. 2, are recesses which receive first the transverse piece g, and immediately on the top of this rests a box, c, which sustains the shaft a', which carries the cam F. A cap, g1, is held in place over the shaft by the set-screw, g2. The transverse piece g, after passing through the aperture, drops below the machine, and'in its center, half way between the side pieces, it is recessed to receive the arm H, Fig. 1. This arm slides freely in the recess, and is itself recessed to re ceive the foot of the cam F. The outer end of this arm is pivoted to the upright lever J, which has its fulcrum at It in the curvilinear cross-piece lf, its upper end being pointed and entering an aperture in a projection of the cap or lid K. The

' cap K is provided with iiauges at its outer edges,

forming guides to keep it in place on the surface of the mold. At each end the cap is supplied with gripers i, Fig. 2, secured with nuts on the top, while the lower end projects under inclined projections or lugs l, forming parts of the side pieces. The object of these gripers is to hold the cap firmly to the surface ofthe mold and sustain the pressure coming from within. In sliding back this cap from the top of the mold the common construction carries it on curved arms, (when I use straight ones at mf,) thus causing the cap to describe an are with the point of the lever J, which, in consequence, elevates the front edge of the cap, unavoidably causing a troublesome accu mul ation of dirt under it. By using the straight projection or arm m. I carry the cap parallel with the surface of the mold, thus always keeping it perfectly free from accumulations, making it a self-cleaning machine. L represents a hook, pivoted to the upper part of the pronged arm E, its lower end dropping over the projection h on the cam; or it may be hung on the face of the arm, and so constructed as to be subject to the movements of the point a; of the cam. The object of this hook is to draw the plunger to the bottom of the mold, the weight ofthe parts not being sufficient to always overcome the tendency of the plunger to stick in the mold. It operates as follows: When the plunger is at the top of the mold the hook drops over the point h on the cam. This securely unites the two until the plunger reaches the bottom of the mold, when the point h forces the hook from h', leaving the plunger free to follow the other movements of the cam. The shaft a is provided, at its outer end, with a square shank, to which is attached a lever for operating the press. This shaft also carries the cam F, which is placed midway between the side pieces, and by a rocking motion imparted to it by a lever it operates, successively, the long prong n of the arm E, the horizontal lever H, and the short prong 0 of the arm E. rlhis cam has been in use, but the long foot 1" has heretofore been placed on the side of the cam, requiring a crook in the lever H. By placing this foot on the face of the cam I obtain a straight arm and a direct pull on the lever operating the cap, thus securing a more positive and steady movement, and overcoming a great objection to the use of this cam. By variations in the shapes of the transverse blocks b band the plunger D, by making them curvilinear or otherwise, I can make different shapes or forms of bricks.

The Vmanner of operating the machine is as' follows: Put a lever on the shaft a. Throwing the lever to the right, the recess t in the cam strikes the long prong n of the arm E, carrying; it upward, bringing the plunger to the top of the mold. At the same time the long foot of the cam i" throws to the left the horizontal lever H, causing the cap K, by movement imparted to it by the upright lever J, to move the projections or arms m, opening the top of the mold. The brick to be pressed is now placed on the plunger 5 the lever is thrown to the left, when the point of the cam h and the hook L unite and compel the plunger to fall to the bottom of the mold, carrying its load with it. At the same time the long foot i" of the cam, by operating on the lever H, forces the cap over the mold, which is held firmly in place by the gripers c'. The short prong o of the arm E is now received in the recess s of the cam, which again raises the plunger, applying pressure to the brick. By again throwing the lever to the right the brick is elevated to the top of the mold for delivery.

I do not claim the general construction of the machine herein shown in view of the patent granted to Jeffery Smedley August 2S, 1844, but

What I do claim as my invention isl. rIhe hook L, in combination with the pronged arm E, clutch L, and plunger D, substantially as and for the purpose described.

2. The clutch h', in combination with the hook L and cam F, provided upon its face with foot 1^, substantially as and for the purpose set forth.

ALBAN ANDERSON.
