IMPROVED BRICKfll/IAGHINE.

TO ALL'WHOM IT MAY CONCERN:

Be it known that I, PETER HAYJEN, of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and improved Brick-Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make anduse the same, reference being had to the accompanying drawings, for-ming part of this specification.

This invention relates to a new and improved machine for moulding and pressing bricks; and it consists of an improved means for'conveying the clay from the crushing or rolling-mill to the press-boxes, and also in a novel and improved construction and' arrangement of parts for moulding and compressing clay, and dischargling the same after being compressed, as hereinafter fully shown and described, whereby the work may be donc with great rapidity, and in a perfect manner.

In the accompanying sheet of drawings- Figure 1, Sheet No. 1, is a side View of my invention, partlyin section.

Figure 2, Sheet No. 2, a plan or .top View of the same.

Figure 3, Sheet No. 3, a transverse vertical section of the same, taken in the line x x, iig. 1, and looking in the direction of the arrows 1.

Figure 4, a transverse vertical section of the same, taken in the line :r x, and looking' in the direction of the arrows 2. i

Figure 5, a vertical section of fig. 4, taken in the line yy.

Similar letters of reference indicate corresponding parts:

The frame of the machine is composed of two cylindrical heads, A A', provided with feet, a, which are firmly secured to any suitable bed, B, and also composed of upright supports,'C, secured to the bed, the sup-y ports C having a hopper, D, secured on their upper' ends. l

E is the driving or main shaft of the machine, having a roller, F, upon it, between thel supports C C, and partially underneath the hopper D. i

The shaft E has a toothed wheel, G, upon it, which gears into a larger wheel, H, at one end of a roller, I, which is parallel and works in contact, or nearly so, with the roller F.

' Motion is communicated to the roller I from the shaft E, and I has a slower motion Athan F, owing to the difference in the size'of the gears G H.

The rollers F I crush and pulverize the clay, which is thrown into the hopper D in a. properly moist state, the crushed or pulverized clay being discharged from the rollers into a hollow cylinder, J, which has a shaft, K, fitted longitudinally and centrally within it, said shaft having a rotary movement given it hy means of a wheel, L, which gears intov the wheel G of shaft E, (see iig. 1.)

The shaft K has a series of spiral wings or blades, attached to it, each of which is a section of a screwthread, and at the discharge-end of the shaft K there are two wings or blades, b b', which form a complete screw-thread, or extend entirely around the shaft, as shown clearly in fig. 1. I l

This shaft K conveys the crushed or pulverized clay, as it'is discharged from between the rollers, to the press-boxes L', which are within a cylinder, M, the latter being placed loosely on a hub or boss, c, through which the driving-shaft E passes loosely, and is allowed to turn freely.

The press-boxesL are placed or made at equal distances apart in the cylinder M, and of rectangular form, correspondingtc the 4desired shape of the bricks to be moulded, and at the outerfor face side of the cylinder M there are radial recesses, d, to receive a friction-roller, e, at the `end ofja crank'armf, on a` shaft, N, which receives its motion4 from the driving-shaft E, by means of gears, O O', the former, O, being on shaft N, andthe latter, O, being on the driving-.shaft E, and connected to and disconnected from it by a clutch, P, operated through the medium of a lever, Q.

The crank-armf thus rotates the cylinder M, and brings the several press-boxes L'. consecutively in line with the discharge-end of the cylinder J, (see figs. 1 and 5,) and at each movement of the cylinder M, a pressbox, L', is carried from the discharge-end of the hollow cylinder J upward, to a point in line with a plunger, R, which is tted horizontally in a bearing,`g, in the head A', (see more particularlyvg. 1.)-

`Besides the crank-armf, for rotating the cylinder M, there are'two teeth, h zLon the end of the crank-arm f, which engage with teeth 3i, between the recesses oZ of the cylinder M, and bring the recesses in proper position, at the required time, to eceive the friction-roller e of the arm f.

Each time a press-box, L', is brought in line with the plunger R, the latter is pressed by means of acam, S,

on shaft N,"said plunger acting upon a follower, T, in the'press-box, and compressing the claytherein, (see more particularly figs. l and 2.) V

As the plunger R is drawn back by the cam, the cylinder M is again turned, and a succeeding press-,box and follower brought in line with the plunger, and the clay in said press-box compressed as before, while the filled press-box, with the previously-compressed clay therein, is'brought in line with a plunger, U,which is* moved by a lever, V, having'itsffulcrum at j, said lever passing through a slot in the plunger R, and receiving its motion from'the saine, so that it. may force the compressed clay (bricks) out from the press-box L'directly in front or' in line with it, upon a table, AW, from which they are taken to the yard er other suitable place, for drying. A

The follower T, after being thus forced inward, to discharge the brick, isA drawn out by a fixed or stationary cam, X, at the inner side of the head A', saidv cam having an oblique outer end, with aflange, lc, at each side, to catch into a recess, l, in the outer ends of the follower of each press-box L', (see more particularly fig. 1.) By this arrangement the'clay may be moulded and compressed into. bricks with rapidity and the greatest facility.

e There are no parts liable to get out of repair, or become deranged byfuse, and the machine may be constructed at a reasonable cost, and maybe worked witha moderate expenditure of power.

I claim as new, and desire to secure by Letters'Patentv 1. The intermittingly-rotating cylinder M, provided with the press-boxes L', followers T, recesses al, and teethe, in connection with the crank-armfon shaft N, all arranged to operate in the manner substantially as and for the purpose specified.

2. The plunger R, operated substantially as shown and arranged, in relation with the lfollowers T, for the purpose of compressing` the clay in `the press-boxcs, substantially as set forth. I

' The plunger U, operated from the plunger R, through the medium of the lever V, for the purpose of discharging the bricks from the press-boxes L', substantially as shown and described.

4. The combination of the pressure-rollers F I, rotary shaft K, provided with the spiral wings or blades b:

and b', the cylinder M, provided with the press-boxes L', with the followers T therein, the plungers It U, and the fixed cam X, all arranged to operate in the manner substantially as and for the purpose specied.

PETER HAYDEN.
