The shaft has a vibrating motion communicated thereto by bracket, e, secured by bolts or otherwise to IOO means of an arm, E2, secured thereon and provided with lugs e", by means of which and a pivot-pinit is connected to a pitman, E3, bifurcated at its front end and connected to a wrist-pin, e5, secured upon the outer face of a gear-wheel, F, mounted upon the outer end of the eccentric shaft C. The size or area of the receiving-chamber e' can be varied to contain a larger or smaller quantity of material, and accordingly increase or decrease the size of the brick, said chamber havinga movable platen, e6, fitted therein andl formed with a plate, el, having a downwardly-projecting bifurcated lug, es, adapted to engage and be operated by a thumb-nut, e9, working in a bearing secured in the body portion e.

G designates the mold-wheel, having a series of molds, g, arranged at an angle to each other, the wheel in the present instance comprising four molds arranged at right angles to each other. The wheel is adapted to be rotated and is arranged between the lower platform, a2, of the frame A and another platform, a, of like character-arranged a distance-above the lower platformequal to the depth of the mold-wheel, said platform a* being supported upon feet or projections a5, affixed to the platform a2. The platform a* is protected `by a plate, a, and is provided with a rectangular opening, a7, with which the opening or orifice of the feeding-chamber c' isadapted to register, said feeding device being reciprocated Aback and forth over the platform a*, and at its extreme forward movement the receivingchamber e', which isbottomless, registers with the opening a and discharges the clay or material into the same and one of the molds g Vof the mold-wheel, each mold ofwhich is adapted to register successively with the opening a6 during the rotation of the wheel, thus accomplishing the charging or filling of the mold in which the brick is to be formed and pressed. The mold-wheel G is mounted or supported upon a vertical shaft, G', passing between the platforms of the frame at or near the middle thereof, and stepped at its lower end in a bearing formed therefor in a bridgetree, R, extending across from side to side of the frame, and secured in lugs r r, depending from the lower surfaces of the horizontal cross-bars c of the main frame. The upper end of the 4shaft Gextends through the upper platform or table ajl of the Vframe A, and isl provided with a stop-wheel, H, intermittently rotated by a revolving drive-wheel, I, mounted on the upper end of a short vertical shaft, J. The shaft J passes through the upper table a?, and at its upper end it is supported therein, while at its lower end it is mounted ina bracket, J', depending from thel undersurface of the table a.Il andI having an arm, j, which receives-the shalt J. The shaft `.I is provided below the platform or table a2 with a beveled gear-wheel, K, by :meansof which'said shaft is rotated through motion transmitted from a .similarbevelel gear-wheel, K', with which the wheel Kl meshes, said gear-wheel K being mounted upon a shaft, L, arranged at right angles to theshaft J,and mounted in abox or journal, l,secured to the under surface of one of the crossbeams a of the main frame. The short shaft L is rotated by motion transmitted A to a spur-gear wheel, L, secured on said shaft at itsouter end, from the gear-wheel F on the eccentricV shaft C, with which the gear-wheel L meshes, as clearly shown.

The stop-wheel H comprises four projecting teeth or spurs, h h, arranged at right angles to each other, and having each a rounded outer face, h h', said teeth being separated from each other by intervening spaces or slots h2 of square form, with a slightly rounded inner face, the slots being cut into the body of the wheel at the corners thereof, and adapted to successively receive a tooth or projection, t', of the drive-wheel I. The tooth t' has a rounded outer face, and on each side it has a curved -or` rounded recess, t", the projection being adapted to fit in the recess h2 of the stop-wheel H presented to it, and impinge algainstthe side walls thereof, rotating said wheel a quarter of a revolution, the remainder of the rounded face of the wheel I registering or fitting in the rounded outer face of one of the teeth h of the wheel H. duringt-he remainder of the revolution of the wheel I until the projection 't' thereof enters the succeeding notch of the wheel H presented toit, and so on. Each of the wheels H I bears upon the upper face of the upper table a?, and is removably keyed to its supportingshaft.

I will now proceed to describe the mechanism for forming and pressing the ,clay or material into the proper shape in the molds.

M M M designate the pressing-pistons, the two former of which are arranged to bear in thegrooves formed at each end of theshaft C, while the latter, M, is arranged in the eccentric groove formed in the shaft midway between the end grooves and at a different angle to said end grooves. The upper end of the shaft M has a concave face formed therein adapted to fit the curvature of the eccentric face of the groove, a removable strapor band, m, passing over and embracing the groove snugly, and secured at its lower ends by a crosspin, serving to keep the follower or Vpiston proper in position while allowing the shaft to rotate. Ihe lower end of the piston-follower M is provided with an enlarged head, m', having side lugs or flanges, mz, adapted to slide in grooves n, formed in a guide-bar, N, extending across from one to the other of the uprights a, to which they are secured, said guide-bar having an enlargement, n', at its middle and arranged above the plane of the mold-wheel G, the molds of which are adapted to fit under and register with'the opening formed in the en- A largement ofthe guide-bar, thus bringing the Y :upper surface thereof, while the pressure-fol- IIS lowers M M operate a pressure-bar adapted to compress the earth or clay in the molds from Vbeneath the same.

The followers M M are each provided with an enlarged head, ma, which carries ay journal or bearing, m, adapted to snugly t in one of the eccentric-shaped grooves of the shaft C. Each follower passes through openings or ap- 'ertures formed iu the lower table a2, and at vits lowerend said follower fits in a socket, o,

provided therefor in the end of a pressurebar, O, located beneath the lower platform or table a2, and provided'with ears or guides o' at each end, which fit between grooves formed in the lower surface of the supporting-frame uprights, or in guides provided therefor, to maintain or vkeep the barin its proper position during the vertical movements thereof. The pressure-bar O isprovided with a platen, o2, secured to its` upper surface at the middle thereof and adapted to pass through an opening in the lower table into the lower end of one of the moldsg,

acting' conjointly with the upper vpiston tok compress and form the earth or clay into the proper shape for the brick.

P designates the ejector for forcing the brick from the mold after'having. been formed and pressed into shape by the pistons and bar,

-said ejector being arranged at one side of the frame and comprisinga ba'r,P', havingan enlarged base, p, adapted to move vertically through an opening formed in the platforms or .tables, andrto force or expel `the brick from vthe molds which are brought to register therewith. The bar is pivotally connected'at its lower end to the base p,which moves between a guide, P2, secured to the table a, said base .having parallel uprights p'-p', between which vby motion transmitted thereto bya pinion or gear-wheel, Q2, secured upon the outer end of the said shaft Q, and adapted, to mesh with the gear-wheel F on the eccentric shaft C, said shaft and gear-wheel Q Q2 being arranged above the gear-wlieel F. The bricks in `their green state, after being forcedfrom the molds by the, ejector P, are deposited onk and car- Y riedxoff by an endless traveling apron S, the

means for operating and supporting which I will now describe. At one side of the main frame is arranged a belt-supporting frame, S', which comprises parallel horizontal arms s s, connected to or` formed at their inner ends with vertical parallel arms 's's', each of which is provided withy pins'sz, two' or more in number, adapted to fit in sockets S2, secured upon the uprights tA of the. main frame, thus permitting the belt-frame to ,be easilyand quickly connected to and removed therefrom. T T' designate thebelt supporting and Shifting rollers, .thee former, of which,-T, isar;

to befitted over the upper portion ofthe machine, said plate being bent or curved, as shown, and provided with securing pins or ICO A f Xiis aA removable shield or cover adaptedv bolts m x, one arranged at each corner, those at the front end of t-he shield fitting in apertures formed in the front ends of the standards Q2, while those at the rear abut against the upper projecting edgesof the hopper D. The operation of my invention is as follows:

lEarth, clay, or other material in a drystate is placed in the hopper, and power by handy vor otherwise is applied to the shaft B, which rotates the shaft C throughv the intermeshing gearing B' C' and causes the feeding carrier orv .plate to be reciprocated away from beneath,

the bottom of the hopper throughfthe medium ofthe gearing F, pitman E3, linkrEz, i

and shaft E', the chamber e' of said `carrier being forced forward to register with the open-f ing in the table a4 and deposit its charge 'of earth, clay, or the like into oneof the moldreceptaclesy g of the wheel G. The mold-wheel G is then shifted around in'position between the pressureplungers by motion transmitted .from the shaft C through thel gear-wheels F L', shaft L, bevel gear-wheels K K', shaft J,

drive and stop wheels I H, and toits supporting-shaft G. As soonas the mold is in posi-l tion between the platensv of the `pressure-j. .plunger M' and the platenof thepressure-bari'v l Y mold-wheel occasioned by the same mechanism and power from the same shaft brings the mold containing thebrick thusformed beneath theexpellingplunger P,operated by thecrankshaft Q and gear-Wheel Q2, meshing with the gear-wheel F of the eccentric shaft C. The brick is forced from the mold by the downward stroke of the plunger P', and is deposited upon the endless traveling apron S, by which itis carried from beneath the machine and -removed by hand for burning in a kiln, &c.

The operation just described illustratesthe manner of forming one brick only; but it will be understood that the forming of a number of brick is only a repetition thereof, the operations of filling and pressing the molds, ejecting and-carrying E the formed compressed brick being successively and automatically performed by a machine constructed in accordance with my invention, without any attention whatever, except the feeding of the material in the hopper and removal of the formed brick from the apron.

The parts of the several mechanisms are so proportioned and arranged'with relation to each other that at the end of every eighth revolution of the power-shaft a mold has been filled and compressed, and a formed brick ejected and carried olf. At the first half of the first revolution of the power-shaft, when ythe machine has been started, the feeding-carrier has been moved forward in position for charging the mold, and at the end of the first revolution of the shaft the carrier has been moved back to be charged from the hopper. Simultaneously with the forward and rearward movement of the carrier the stop-wheel I is rotated, and at the beginning of the second stroke it begins to rot-ate the stop-wheel H, on the shaft of which'the mold-wheel G is mounted, and thus at the end of the second revolution the charged mold is carried away from beneath the charging or feeding carrier, and i its place supplied by another mold for filling.v At the end of the third revolution the second mold has been filled and the stop-wheel moved half-Way round, and at the terminationof the A fourth revolution the mold first charged has been shifted between the platens of the pressure-plunger. During the first 'half of the fifth revolution the pressure -plungers are forced against the Aearth .or clay to form the brick, and at the termination thereof they have been drawn away from the mold. At the first half oi'- the sixth stroke the mold i containing the pressed brick is shifted beneath the expellingplungelyaud at the end of said revolution the brick has been expelled from the mold by the `downwardpressureexerted bythe ejectorP,

and deposited upon the endless carrying-apron S, the remaining two revolutions of the shaft moving the apron with the formed brick a sufficient distance to clear the machine, from whence they may be removed by hand.

A machine constructed in accordance with my invention is simple and durable in construction, efficient and automatic in operation, can be readily transported or moved from place to place, requires a minimum expendi- Y ture of power, is compactly constructed and works by positive motion, and is consequently not liable to get out of order.

It will 'be observed that the plate e of the vibrating carrier E projects beyond the edge of the body thereof and that the same covers the orifice of the hopper D, thus preventing the escape or waste of the clay or material when the carrier is4 at its forward stroke.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, `is- 1. In a brick-machine, the combination of a frame, a poWer-shaftjournaled therein,a shaft, J, carrying a mold-wheel at its lower end, and having a stop-wheel provided with a single tooth, a-shaft, G', having a drive-wheel, I, and a gear-wheel, K, and a shaft, Z, geared to the power-shaft, and having a gear-wheel,K,sub stantially as described.
