IMPROVEMENT IN THRASHERS AND SEPARATORS.

- Specification forming part of Letters Patent No. 221,463, dated November 11, 1879; application filed June 26, 1879.

To all whom it may concern:

Be it known that I, PETER HORN, of Hagerstown, in the county of Washington and State of Maryland, have invented certain new and useful Improvements in Thrashing-Machines and Grain Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings and to letters of reference marked thereon, which form a part of this specification.

In the accompanying drawings, Figure l is a top view of myimproved thrasher and separator. Fig. 2 is a side view of the same. Fig. 3 is a longitudinal vertical section. Figs. 4, 5, and 6 are detail views.

Upon the frame A are mounted the thrashin g-cylinder B, the fork or straw-shaker O, and straw-carrier D, in the rear of which is the stacker E.

The fan F is placed directly underthe thrashing-cylinder, and the sieves G and H are under the fork or shaker, thus making the machine very compact.

The grain is fed into the hopper I and thrashed by cylinder B in the usual way, when the straw passes upon the fork O, which is shaken by means of the cam Jon the shaft of the flanged cam-wheel K, which will here inafter be more fully described. This fork has two sets of tines or teeth, 00, in order to divide and thoroughly separate the straw, and thus expose the same to the blast, and facilitate the escape of the grain.

The front teeth are short, and they divide the bundles and scatter the straw loosely upon the longer back teeth.

Both the fork and the sieves G and H have a lateral motion, being shaken by the elbowshaft N, which is rocked to and fro by means of the crank-pin O and connecting-rod P, Fig. 2. The sieves are shaken by means of the flanged wheel K, the rim of which runs between two friction-rollers, R, on the arm S, extended from the sieveframe. The flanged wheel also shakes the straw-carrier D, the rim of the wheel being bent to form a cam, and runningin a grooved pulley, T, on the shaft of the lower rollers, over which the straw-carrier runs. By this arrangement the inner or receivin g end of the straw-carrier is shaken sidewise, while the band U gives it motion on the rollers.

The front shoe, V, has a down-set, W, and an adjustable wind-gate, X, to regulate the blast and direct the same more orless upon the clown-set directly under the axis of the fork. Another adjustable wind-gate, Y, is placed in the passage between the down-set and the back shoe, Z. These wind-gates are held at any desired angle by means of a hasp, a, which hooks into one of the notches on the plate b, Fig. 1.

The stacker E is attached to the frame by means of S-shaped swinging braces cl, so as to be folded over upon the top of the frame for transportation. This brace is pivoted at both ends, as seen in Fig. 5, and, by their peculiar shape, act as supports for the stacker when unfolded, as shown in Fig. 1.

On the mouth of the discharge-spout is attached aself-lockin g bag-holder having a rocking elbow-shaft, e, to which is hinged a lever, f, for holding the bag and for raising and holding the slide 9. When the elbow-shaft c is raised the lever f is employed to raise the slide and lock the same. The mouth of the bag is hung upon the wide end of this leverf, which thus holds both the bag and the slide; and when the bag is filled the lever and elbowshaft are tilted, and drop with the slide, as seen in Fig. 4.. The fan is provided with an adjustable slide, 9, to regulate the blast.

Having described my invention, what I claim is- 1. The combination, with the thrashing mechanism, of a shaking-fork, (3, arranged in rear thereof, and provided with short teeth, 0, and long teeth, 0, arranged on differentplanes, substantially as and for the purpose herein shown and described.

2. In athrashing-machine, the combination, with an endless revolving straw-carrier, D, of the grooved pulley T, and revolving cam K, whereby said carrier is adapted to receive a laterally-vibratin g movement, substantially as specified.

3. The combination, with the fork O, of the revolving cam J, crank-pin O, elbow-shaft N, connecting-rod P, and revolving wheel K, for

giving vertieally-slmking and laterally-vibratintermediate connecting mechanism, whereby ing motions to said fork, substantially as and said shoe, straw-carrier, and fork are simulfor the purpose herein shown and described. taneously vibrated, substantially as and for 4.
