I UNITED STATES PATENT EIFE- RILEY H. C OON AND WILLIAM H. GOON, OF ONEIDA LAKE, NEW YORK.

THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,791, dated August 16, 1881.

Application filed January 31, 1881. (No model.)

To all whom it may concern:

Be it known that we, RILEY H. OOON and VVILLIAM H. GooN, of Oneida Lake, in the county of Madison and State of New York, have invented certain new and useful Improvements in Thrashing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a longitudinal vertical sectional view, and Fig. 2 is a detail view, in perspective, of the operating mechanism.

Similar letters of reference indicate corresponding parts in both figures.

This invention relates to thrashin g-machines; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the frame of the machine, upon the sill B of which boxes or bearings O are provided for a double crank-shaft, D, the cranks E E of which are located closely adjoining the sides of the frame. The shaft D is provided with a drum or band-wheel, F, to which the motive power is applied.

G is ashaft, boxed or journaled in the sides of the frame, above and in rear of the shaft D. Shaft G is provided with a single central crank, H; and upon its ends, inside the framejare keyed or otherwise secured two triangular plates or levers, I I, provided upon their inner faces, below the shaft G, with wrist-pins J. Pitmen K connect the cranks E of shaft D with the lower ends or corners of the plates I, to which a reciprocating motion is thus imparted when the machine is operated.

The separator or straw-carrier consists of two parts or sections, L M, the front one of which, L, is suspended by its front end, by means of rods N, under the concave O of the cylinder 1?, from which it receives the grain and straw in the usual manner. The rear end of section L is pivoted to the upper corners of the plates I, which impart to it a rearward and upward throw, thus separating the grain, which drops upon the grain-table, from the straw,which passes over the fingers Q, arranged upon the rear end of section L, and drops upon the section M. The front end of the latter is pivoted to the front corners of the plates I, and its rear end is suspended by rods R, at the tail end of the machine. The upward and rearward throw imparted to section M by'the levers or plates I separates the straw from the remaining grain, and finally drops it upon the ground or upon the stacker, as the case may be.

The front end of the grain-table S is supported upon pivoted rods or cranks T, and its rear end is pivoted to the wrist-pins J of the plates I, which give the said table a short upward and rearward throw, which carries the grain and chaff to the sieves or riddles U. In the arrangement of the latter and of the fan V, table or conveyer W, (which carries the waste grain from the tail end of the machine back to the riddles,) and of the beateror picker X, rear of the cylinder, no novelty is herein claimed.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of our invention will be readily understood. It will be seen that the sections L and M of the separator move in the same direction at the same time, thus causing thelatter to receive the overflow from the former, and complete the operation of separating the grain in a more thorough and satisfactory manner than can be done where a single separator or straw-carrier is employed. At the same time no increase of n10- tive power is demanded, both sections being actuated by the plates or levers I I,npon which they counterbalance each other, as shown. Through the same medium of the plates I I the grain-tables or conveyers S and W are alsooperated, the former being pivoted to the wrist-pins J, and the latter being connected, by means of a bent rod or pitman, Y, to the crank H of the shaft G, upon which the said plates I are keyed or otherwise secured, as above stated.

In testimony that we claim the foregoing as In our own weliave hereto affixed our signatures in presence of two witnesses.
