Specification forming part ofLetters Patent No. 4,916, dated J annary 1, 1847. l

To all whom t'may concern: f A

Be it known that I, ULrNToNFos'lEmof the county of La Porte, andl State of Indiana, have invented a new and useful Machine for Cutting and Harvesting-Grain, which I call Fosters Harvester l and Ifdo hereby declare A that the following is a full, clear, and exact de-v ,principal wheels oh which the machine rests,

one ofwhich, B b, havingwi'thi-n its fell y a concave toothed wheel, C C, and which is the tirst mover of the whole machinery; D D D, spokes of the wheel B b; E, the dotted line showing the hub and axle of the wheel B b. F F are slidin g joists, in which the axle ofthe wheel B b These sliding joists are moved forward and backwardv by means of lever G, which lth rows the concave wheel C C outor into gear. H, dotted, is a pinion working into the concave toothed wheel C C. This pinion is on the -axleI ofxanother concave-toothed wheel, K, supported by frame L. M is anotherpnion on the shaft of the drum N, meshing intotheconcave toothed wheel K, (shown in dotted lines;)

l ,0, box of the shaft of thrashingdrum, secured f to frame L; 'P, a pinion on the shaft of the fanQ, carried by the concave-toothed wheelK; R, a pulley (doublelon .roller -S,to give motion' to. revolving cloth T. U U U, &c., are cleats across the revolving cloth T, to keep it in a proper position as well as to act as elevators; V V, upright posts' to support the shaft '.of the roller S.' The revolving cloth Tre ceives the straw and grain from the thrashingdrum, elevating them to the raker W, the grain chieiiy fallin g between the roller S and the raker W into the sieve X. Yis a cylinder within the cylindrical raket-VV, to gage the projections of the prongs Z ZZ, &c., which, in the revolutions of raker W, are projected and withdrawn by their own gravity as often v as they reach a vertical position. These prongs machine or teeth are intended to separate and remove the -straw from the grain. a a., posts to support the shaft of the raker W; Vclo o, bands passing over the double pulley R, to put the apron on revolving clotlrland the raker W in. motion. ,d is .a slide-board, onwhichthc grain is deposited by the revolving apron'i., and slides down upon the thrashingdrurn N; e, a platform. `mr,8tc.,'dotted lines, shows the box whichcovers and/incloses the upperpart of thethrashing apparatus;fff, the frame of the reaping or cutting machine, strongly attached =to the frame-pieces L ofthe thrashing g1g g, 85e., areA wooden points, projecting in advance of the cutters, to divide'aud gather the grain; h h h, Snc., the cutters;t' i,

- an iron or steel har above and across the'cutters, sharp' on its front edge, to assist in cutting the grain k k, a har under the cutters, similar' to i l l, Src., iron rods, to which the cutters h h h are attached by screws, the other end of which rods are secured with collars upon the eccentric wheels m m m, &c., which move the-cutters forward and backward; n, the shaft upon -which the eccentric wheels m m,'&c., are secured, at one end of which is the pinionO, meshing into the concave wheell G, p' is aI small beveled wheel at the other extremity `of shaft n, meshing into a' similar wheel, q, turning the shaft i' and with it the roller s s; a, a wheel .to support the cutting apparatus traversing in frame fn,- w w, rests for the shaft r, secured to the frame j' f; oo, a brace; y, a post; Z, a rail outside of L and .parallel with it'. Betweenv theA rails L and Z a wheel corresponding in size to the wheel B b 'is to be used, when then the cutting appara- "tus is detached and the machine used only as a thrashing-machine. A The axle of this wheel works in the holes o c o c. t'v t' is a joist coumeetingl the framefof the cuttingmachine to 4 the frame L of the thrashing-machine; j, a box (not shown in the drawings) under the Wagon to receive the grain.

Fig. 2 shows the thrashing-drum with such parts as are attached when the machine is used only for thrashing. A A represents the frame; B, the thrashing-drum; C, apulley ou the axle of the drum; D, a slide-board; E, a roller with crooked teeth'to draw the 'unthrashed grain uniformly toward the drum; F, a pulley on the shaft of roller E. Gr is a .pulley upon `another shaft, in which the knives la k k are secured, and which cut the bands of the sheaves before they reach the drum B, H H, &c., dottedlines, is the'covering inclosing the drum, &c.; I I, the bauds on the pulleys.

Fig. 3 shows the internal structure of the raker W; X', the inner cylinder; y, the shaft;

Z Z Z, the prongs or teeth. b b b, &c., are the A, a view from above; C, the wooden pointsl in advance of the cutters; '1),' the upper iron plate; E, the cutters, triangular and sharp at base a a.; F, therod connecting the cutters with the collar on the eccentric wheels m m, &c., in Fig. l; b, b, the fastenings of the cutters to the' rodF.; c e, the fastenings of the upper bar, D, tothe lower bar, G, (not shown in the drawings) by screws; d d, the framepiece, in which the rods F move in boxes.i B is a side view 'e e, the boxes, with square holes for the rods. j', in dotted lines, shows the length of the stroke given by the' eccentric wheels. g g, dotted lines, shows the space through .which the grain passes to be cut by the backward motion of the cutters E.

The operation of the harvester is as follows: Horses are attached as to a common wagon. The large wheel B b receives motion as the horses advance, and thus the concave toothed wheel G moves the pinion on the axle of wheelK. The concave of this wheel K meshes into pinion M on theshaft of the drum and also into the pinion P 'on the shaft of the fan, giving motion to both. 'The wheel C also gives motion to pinion o on shaft n, giving motion to the eccentric wheels m m m, -&c., by which the knives h are also put in motion.` p is a beveled pinion on shaft n, working in a similar pinion, gnou shaftw', which carries roller s.

and with it -the apron t. Thusas the'machine ,advances the grain is cut and falls upon the apron t, an'd is elevated to the slide-board d, sliding thence under the drum, which casts it violently up upon the revolving cloth T, which is moved by band c c, which is carriedby a pulley ou the axle of K. This revolving cloth T carries the straw and grain over upon cylin drical raker W, which is moved by band c, separating, the straw and grain, the former being carried over the raker, and the grain.

fallingl between it and the revolving cloth T, nponthe sieve .'v. The sieve is shaken by pins in the felly of wheel K, tilting a lever. (Not shown in the drawings.)

This machine may be used merely for thrashing, either-traveling or stationary, when the cutting apparatus is detached and a wheel ot' the size of B b is applied at c c c c on L and 4 Z, also the two rollers sho'wn in Fig. 2,-one

of which having sharpnknives to cut the bands," the other with curved teeth to draw the'grain v within reach of the drum. These rollers receive their motion from ay double-pulley, c, on the shaft of the drum by bands I and I, the band I being crossed, the remaining part ot' the operation as before described.

What I claiinqas my invention, and desireto CLINTON FOSTER.
