WILLIAM H. HOVEY, OF SPRINGFIELD, MASSACHUSETTS.

IIVIPROVED BRICK-MACHINE.

Specification forming part of Letters Patent No. 52,852, dated February 27, 1866; antedated February 16, 1866. i

To aZZ whom fit may concern.'

Be it known that I, WILLIAH H. HOVEY, 0f Springfield, Hampden county, Commonwealth ot' Massachusetts, have invented a new and Improved Brick-Machine 5 and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to letters of reference marked thereon.

In the drawings, Figure 1 is an end view;

. Fig. 2, a side view, and Fig. 3 a plan with part of the mechanism removed.

The subject of brick-machines has been so long and thoroughly discussed as to render it unnecessary for me to enter into any explana tions or remarks in regard to the utility of such invention; and I will therefore waive this and commence immediately to -show the construction and operation of my invention, and also some of its advantages over others ofthe same sort.

It consists of a frame, A, supporting and holding in place the mechanism, a hopper, B, in which the clay is cut and ground to the proper consistency by the knives b b on the shaft C, turned by the bevel-gear c on C and eZ on the main or driving shaft D, which is connected at E to a suitable power, usually steam or horse.

Under the hopper B are two boxes or channels, Z Z, into which the clay falls through the openings ej'in the bottom of the hopper B. In these boxes or channels two plungers, F F, work backward and forward, moved by the knee-joint levers G M andG H. These levers, connected by the piece 3, are moved by the cam I on the shaft J, which receives its mot-ion from the driving-shaft D through the bevelgears K L. This cam acts on the lever by the rollers 7c k on each side. These channels Z Zl are connected in all directions after they pass the openings e j', and near the front they are each divided into two spaces by the partitions m m, and at the frontfrom four openin gs, au o o.

The cutters or knives O P now remain to be described. `These each consist of two knives7 p p', fastened on the piece Rin such a manner that the space between them shall be equal to the length of the bricks to be made. These are attached to connections s t, which extend -side two bricks. ues down, the lower edge passes the bottom of action of the knives b b. It then runs into the boxes Z Z through the openings ef, and is forced by the plungers F F', operated by the levers G H, into the contracted space in the front of the partitions m on', so as to make two bricks in front of each plunger. These are new cut off by the knives or cutters O I), and at the next push of theplunger are forced out through the openings a u o o onto the band or apron b and all carried off.

It will be seen that in the mechanical arrangement of the cam I and knee-joint levers G H and'G H', connected by S, I obtain a very powerful and sure pressure on the plungers, and also that the strain andthe machine is received on the rods 2 2 at the sides, which bind together the two ends of the machine,'

and thus make it very strong where strength is most needed.

As the clay is pressed before the plunger along the channel Z the superuous clay is pushed up into the hopper, so that only just the right amount of clay can be got into the channels Z Z before the plunger. As this is pressed along,the channel, contracting,presses the clay together, so that when it arrives near the front it is very much hardened and conipressed, forming, if desired, pressed brick, the pressure varying with the amount of contraction. As the clay is pressed along it comes under the cutters O l), and they coming down cut off sufficient of the mass to form on each Now, as this cutter continthe opening and the clay is completely inclosed on all sides, and as the cutters continue their motion downward the piece R strikes plate Y and gives a further pressure to the brick, which tlls out and smooths off the whole surface and fills out the corners, and

^ *the clay to fall easily into the cha-nnels underv any length may be formed by this machine.

stantially as described.

also the cutters, in moving back, smooth off the sides. These knives of the cutters are beve-led on the lower inside edgeso as to cut the brick more smoothly.

The plungers F F are faced with a piece of hard wood, 4, to give asmooth and moistened surface to this end of the plunger, so that the clay may not stick to and be carried back with it, as would be the case with iron. The brick having been cut off, at the next push of the plunger it is forced out onto the band U, which is caused to move from the machine by the revolution of the roller U, operated, as before mentioned, by the cam T through the levers S S and rods V V, and paWls and ratchets X X W W.

The openings e fin the bottom of the hopper are beveled on their upper edges to allow neath.

It will be seen tha-t by removing the cutting arrangement and forming the openings n fn o o differently tile-moldings, Src., of almost Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is.-

1. The combination of the cam L, knee-joint levers GH and G' H', connection B, and plungers FF', when used in combination with a suitable feeding apparatus and frame, sub- 2. The combination of the cam T, one or l more levers, S S, suitably connected thereto, one or more cutters, O P, and a similar number of boxes or channels, l l, through which the clay1 is forced, substantially in the manner and for the purpose described.

3. The combination of the cam T, lever or levers S S, connecting rod or rods V, one or two pawls, W, and ratchet X, and the roller U, substantially in the manner and for the purpose described.

4. Contracting the channels Z l at the front, substantially as described.

5. The combination of the pieces Y Y, rods y y, and spring Z with the channel or channels u u, substantially as described.

G. The combination of the hopper B, having the opening or openings @fin its bottom, with thecchannel or channels l' l and a suitable arrangement for forcing the clay along this channel or channels and for cuttin g oft' and removing the same when formed into bricks, substantially as described.

7. Forming the channeled chamber Z in such a manner that when the plunger reaches the front end of the opening ef there shall be sufcient clay in the space between the front end of and the point to which it inust travel to form the amount of bricks required, substantially as described.
