A. 'W. MANTLE. THRASHING MACHINE.

Patented June 5,1883.

THRASHlNG-MACHINE.

srncrrrcn'rron forming part of Letters Patent No. 278,716, dated June 5, 1883.

Application filed September 6,1882. (No model.) Patented in Germany November 17, 1881, No. 18,382; in England March 31, 1 882, No. 1,503; in Belgium May 22, 1882, No. 57,999; in France May 24, 1882, No. 149,169, and in Austria-Hungary September 29, 1882, No. 23,692.

and ofAustriaHungary, No. 23, 692, dated September 29, 1882.

The object of this invention is to simplify and cheapen the construction of thrashing-machines, and also to render them readily adapta ble to different kinds of grain.

The accompanying drawing is a vertical longitudinal section of my improved machine, designed to illustrate my invention.

A designates the thrashing drum or beater; B,the concave or breasting, and C an inclined chute or chute-board hung beneath the breasting. I) is the straw-shaker, and I the frame thereof.

E is the caving riddle or riddles, and K the flame or shoe thereof. The riddle E or its shoe K is suspended by four hangers, H H, one at each corner, (but two of which are shown,) so that it is free to reciprocate in a direction longitudinally of the machine. It is so reciprocated by means of a crank, G, and pitman F,

as usual. There should be two cranks and pitmen at opposite sides of the machine. The front end or portion of the straw-shaker D or its frame I is mounted on and fixed to the shoe K, straps X X being preferably used for connecting them. By this means both strawshaker and caving-riddles are reciprocated -together and by the same mechanism, instead of being hung and moved independently, as most commonlyheretofore constructed. The strawshaker D is formed with a hinge or j oint, L, near its front end, so that the portion to the rear of this joint may be raised or lowered independently of the portion to the front thereof. This joint may be placed somewhat forward or back not subject to undue vibration.

of the position shown, or even at the extreme riddle on which it is mounted. The rear end of the shaker is supported from the cavingriddle by any suitable adjustable connection, but preferably by a screw, M, and nut N, as shown, so that 'by rotating this screw in the nut the inclination of the shaker may be easily and accurately adjusted.

The'chute-board O is suspended by four hangers, H H, two of which engage its right and left rear corners, while in the construction shown the other two engage the front corners of a shoe, (1, to which the chute is fixed rigidly. This shoe is in a distinct compartment of the casing of the machine, separated from the main or thrashing compartment by a partition, I), and the chute 0 passes freelythrough an opening in this partition. The ob ject of this construction, which forms 110" part of my present invention, is to utilize one set of hangers and one reciprocating crank and pitman for hanging and reciprocating both the chute G and shoe (1.

A crank, G, is formed on the crank shaft, with its throw to the opposite side from that of the crank G, and a pitman, F, connects this crank with the chute C, by which means the chute and shoe (4 are reciprocated coincidently with and in opposite directions from the caving-riddle E-that is to say, the chute and riddle move alternately toward and from each other, so that, being approximately of equal weight, each sustains the thrust of the .reciprocations of the other, so that the frame of the machine is relieved from strain, and is The chute C is so arranged that it receives the grain and cavings or short straws which fall through the breasting B, and, by being inclined backwardly, conducts them onto the caving-riddle E. The straw discharged by the beater A is thrown onto the straw shaker D, where it is agitated and travels to the rear end of the machine, whence it is discharged. The grain that is carried onto the shaker with it is disengaged by its agitation, and falls through the shaker onto the caving riddle E or onto a chute, cl, which carries it forward, and finally drops it on this riddle. The caving-riddle inclines to'the rear,'and by its agitation the cavings are delivered at the rear of the machine, while the grain drops through onto a chute, e, which conveys it to a screen or riddle, f, whence it falls on another chute, g, which delivers it onto a series of screens,-h, h. After falling from chute e, and before reaching screens h h, the grain is subjected to a current of air from a fan, i, which blows out the chaff. This portion of the apparatus constitutes a first cleaning or winnowing mechanism, such as is common to thrashers. The chutes e and g and the screens f and h h are all mounted in a downward continuation of the shoe K, and reciprocate with the caving-riddle E.

From the screens h h the grain is conducted to an elevator, j, by which it is carried through an inclined trunk, 70, (shown in dotted lines,) to the top of the compartment in which is the shoe a. This shoe contains the screens of a second cleaning or winnowing apparatus, receiving air from a fan, on, by which apparatus the grain is finally cleaned and the several grades are assorted and deposited in separate receptacles. For a more complete description and illustration of this second cleaning and assorting apparatus, reference is made to my application No. 71, 241, filed simultaneously herewith.

I claim as my invention- 1.v The combination, ina thrashing-machine, of caving-riddle E, shoe K thereof, crank G and pitman F, for reciprocating said shoe and riddle, straw-shaker D, mounted on said shoe above said riddle, so as to necessarily reciprocate therewith, a joint, L, at or near the front end of said shaker, whereby the portion of said shaker to the rear of said joint may be inclinedto difierent angles, and an adjustable support interposed between the rear end or portion of said shaker and the shoe, whereby the shaker may be set at any desired inclination, substantially as set forth.

2. The combination, in a thrashing-machine, of the'thra'shing-drum A, breasting B, reciprocating chute 0, arranged thereunder, cavingriddle E, arranged with its higher end beneath the delivering end of said chute and its lower end remote therefrom, suitable means for reciprocating said chute and riddle simultaneously in opposite directions, and the strawshaker D, arranged above said chute and be yond the thrashing-drum, and mounted above and fixed to the caving-riddle, so as to recip rocate therewith, substantially as set forth.

3. The combination ofcaving-riddle E, means for reciprocating it, the straw-shaker D, mounted upon and above said riddle, and with its rear end fixed thereto, a hinge or joint in said shaker near or at its rear end, and means for raising or lowering its front end relatively to said riddle, whereby the inclination of the straw-shaker may be adjusted without changing the inclination of the riddle, while both re= ciprocate together, substantially as set forth.

4. In a thrashing-machine, the combination of the cavingriddle E, shoe K, and straw shaker D, all suspended by hangers H H, joint In in said straw-shaker, and screw M and nut N, for adjusting the inclination thereof relatively to the oaving-riddle, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. ALFRED \VILLIAM HANTLE.
