- To all whom it may comcrm.

Be it known that I, BENJAMIN'D. BERRY, of Ed wardsvillc, in the county of Madison, and State-of Illi-- I Figure 2 is a plan of the machine without the hop per, having, as proposed in a-fiill-sizedmachine, two valves in the pressing-box, instead of one I Figure 3 is an outside view in elevation of the connecting-rod, or arm, which movesthe piessingbox.

My invention consists in improvements in b1ick-m achin'es, to equalize thequantity of clay used in forming a brick; also in equalizing and regulatingthe strain on the machine in pressing the brick; in providingcertain and efl'ectual means for giving equal pressure to all', sides of a brick while being moulded and pressed; in providing means, by automatic movement, for receiving and removing the brick from the machine after the same are moulded and pressed; in reducing the amount of friction on the machine; and also in the mode of discharging the waste clay fiom the hopper while the machine is in motion, to be hereinafter fully described.

In the drawings-- A represents the Irame;

B, the bed-plate.

O O are the two master-cog wheels, one on each side of the machine, giving to the same motion by means of pinions a a, as clearly shown in the drawings.

1) represents the main shaft by which ll the appliances' are moved. On it are formed two eccentrics, b b, which, in revolving, move levers c 0', their functions to be hereinafter fully explained.

E E are long arms, receiving a slight forward and backward motion by means of other eccentrics attached to main shaft, and situated inside the collar of each arm. These are not fully shown in the drawings, as they form no part of my improvements, being used in other brickmachines. The other ends of these arms are attached to (one each side) and move a presser or plunger, d.

Another presser or plunger, 0, arranged opposite the other, is moved forward and back by a short arm, F, which works on shaft D, by-means of an eccentric attached to the same, and working in collar of said shaft.

' Not forming a part of the invention, it is not shown in the drawings. These presses are thus moved together, and press the monldedclayl A space, 9, shows the situation of the brick.

Also placed on said shaft D, are two cam-pins f f.

These pins, at each revolution of the shaft, strike the uprights of ratchet-frame h h, moving them forward. The lower ends of the frame are pivoted to the machine-frame. -As this frame h moves forward, it

' carries with it a ratchet-foot, c, which shoves the brickcar G ahead one match or notch. This frame and foot are brought backin place, ready to push forward the car at next revolution, by means of spring j. If desired, or preferred, a weight may be used, instead of the springs. To hold the car in'place after it has been pushed forward, I employapawl, k, which falls by its own weight, the lower end of the pawl dropping into the notch ahead of the one the foot has just left-the situation shown in fig. 1.

H represents the pressixig-box through which the pressers d 0 move. l

Fig. 1 shows the pressing-box with only one moulding-chamber, but it is my intention, in a full-sized machine, to use two, as shown in fig. 2.

This pressing-box is placed across the top of the machine, and is moved forward and back over the two pressers, by means of two arms, I I, (figs. 3 and 4 show them detached,) attached to the pressing-box.

The ends of the arms are made adjustable, by providing each'arm'with a screw-thread, shown in figs. 3 and 4, and are fastened to the pressing-box by nuts 11 n n. n, by which means they can be-easily and readily adjusted to meet the face of the pressers as may be- At the other end-of these arms, and on the outside, are attached wrist-pins l l, which come in contact with cams m m, situated inside of and on master-wheels O O.

Nearly opposite the wrist-pins, and on the inside of the arms, are attached rollers o o, by which said arms are supported on the frame of the machine, the rollers being kept on their respective ways by means ot guides P P. This arrangement obviates a great amount of friction and that torsional strain experienced in the slot and slide-methods used in other brick-machines. Attached to and extending up from each of these arms, is a standard, q, in the top of which works a rockof the cut-ofl, and forces into the mould, orpressingbox, and retains there, the exact amount of clay left in the hopper by the action of the cut-off, as will be hereinafiier fully explained. k

This rock-shaft and pitman obtain their movement by meansyof arm u, attached at one end to the rock- 'jishaft, the other end being provided with awrist-pin, '0,

moving in cam k, on outside of master-wheel O.

Immediately over the mould-opening or openings 2, 'is situated a hopper, L, which is provided with acutofi', or scraper, w, moving endwise back and forth in the hopper, to out oh the exact amount of clay to be used for the formation of the brick.

This is done in conjunction with an adjust-able furring, 3/, situated in the lower part of the hopper, and made adjustable by means of a screw, 2. (See fig. 1.)

The motion of this cut-off is produced by means of a leader, or arm, M, one end attached to the cut-ofi inside the hopper, the other end arranged on a. rockshaft, N, which moves in brackets 1 and 2, attached to the outside of the main frame.

One end of this rock-shaft is provided with a crank and wrist, O, which receives its motion by the cams P 1? locatedon the outside of the master-wheel O.

'Undemeath the pressing-box and pressers, is located a gate,X X, provided'with vertical fingers 8 and 9,.for the purpose of receiving and delivering the bricks when made. This gate moves up and down in guides fastened to the frame by means of four levels, two on each side. The upper two, cc, are pivoted atone end, shown" at 3, to mam frame. Near the other end they are pi vi'oted toa yoke, Q! Their extreme ends are provided with rollers 4, 4', which travel on the .outer surface, or periphery, of the eccentrics'b b, which raise and lower the yoke Q.

Near the lower part of this yoke are pivoted large levers R R. They are also pivoted at 5 to hangers S S, which act as fnlcra to the levers.

To the other end of these levers are attached pitmen 6 and 7 which operate the gate. v

The upward and downward vertical movement of the gate is produced by the levers c and R, and yoke Q, by

the action of the eccentrics b b on main shaft, all of which 'are above fully described.

When the eccentrics b b are at their lowest point, they press down the levers, which raise the gate to its required position to receive the brick from the mould, or pressingbox, on the end of the fingers of the gate. When the eccentrics are at their highest point, the gate, by action of the side levers, is lowered, and deposits the brick on the car G, by means of the depressing-bar T, provided with springs 10 and 11, for adjust,

ment of the same, which performs its work in union with the gate, by a movement received from a rockshaft, U, and arm, -V, the-flatter receiving its motion .from a cam on the inside of the master-wheel O, by detaching the brick from the end of the presser, and

placing the same on the fingers of the gate, as before described, and by them placed on and conveyed forward by car G.

This car runs onways W, which are provided with grooved rollers 12, 13, 14, 850., being, in fact, an intersection of rollers, so regulated as to accurately receive and maintain the cars in their position and correct working in conjunction with the movements of rachet i and holding-pawl is, passing the brick, when made,

clear from under the pressing-box and face of pressers, or plungers, at every revolution of the main shaft, thereby ,leaving another section on the car G clear, and in position to receive the next-made brick, when deposited by the gate X X, thus obviating the possibility of a brick being carried up again on the return of the gate to its duty, as pre iously, described.

As many cars maybe used as desired, each car being providedwith self-acting couplings.

-My inventions, within described, can housed, and are necessary'to the manufacture of brick by any machine, of whatever form.

The advantages of my improvements are to reduce friction in the working of brick-machines, and "consequently require less inotive-power.

They work and move automatically, and therefore save alarge amount of manual labor.

They prevent a waste of clay, and insure the production of a more finished, hard, and. durable brick than can be produced by any other known means or machinery.

A uniformquantity of clay is secured in the mould, and all unequal strain on machinery isthereby avoided.

By the operation of the valves, .the clay is held in position in the mould while undergoing pressure, and by this means a uniform-pressure on all sides is pro duced'.

The bricks are depressed from the mould, received on the cars, and moved ofi with precision and regularity, thus avoiding all injury by handling.

The various parts of the machine work together antomatically. 1

. I do not claim, the main frame, the mould, pistons, perforators, master-wheels, and bed-plates.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the hopper L, slide or cut-oil w, the arm or leader M,-rock-shaft N and strip 3 all operatingsubstantially as above described and shown.
