TIMOTHY-CLEANING ATTACHMENT FOR GRAIN-=SEPARATORS.

CsPEGIFICATION forming part of Letters Patent No. 537,602, dated April 16, 1895.

Application filea r r'w 1,1895. Serial No. 536,905. (Nomodelh To aZZ whom it may concern.-

Be it known that I, EZRA G. CLYMANS, a citizen of the United States, residing at Waynesborough, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Timothy-Oleaning Attachments for 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. This invention relates to attachments to the grain cleaning devices of separators or thrashing machines for the purpose of adapting them to clean timothy or other small seeds.

This invention consists in the novel construction and combination of the parts hereinafter fully described and claimed. I In the drawings: Figurel is alongitudinal section through the grain cleaning devices of a separator, showing the timothy cleaning de-' vices in position. Fig. 2 is a plan view showing portions of the same.

A is an inclined board which conducts the grain and tailings to the cleaning devices, the

straw and light chaff having been previously lower grooved cleaning roll I) are journaled in the sides of the casing B, and are provided with toothed wheels B operating to revolve them in the same direction.

C are two side plates supported in the casing B. a

D is the upper grain plate provided with a fluted plate (1 and supported in front of the upper roll.

E is the second grain plate provided with the fluted plate 2 and supported in front of the lower roll.

. G is the third grain plate secured to the side plates 0 below and behind the second grooved roll.

K is a gatherboard which catches the grain which falls from the grain plates; and the grain spout (not shown) is at the lower end of the gatherboard' K.

N is a shaking shoe supported on the upwardly and rearwardly inclined guides n, and

arranged behind the cleaning devices; and 'n is a slidable frame supported in the shoe N and provided with inclined slats for catching heavy rubbish and discharging it out of the rear end of the machine. I

J is the tailings spout behind and below the third grain plate G, and under and in front of the shoe N.

The gather-board K and the shoe Nare vibrated longitudinally by means of the eccentric rods m, which are operated by the eccentrics m secured upon the shaft N of the straw elevator, to which rotary motion is imparted in the usual manner by the belt pulley p.

O are rods which connect the shoe N with the eccentric rods, and the said rods 0 also support the gatherboard K. The free ends of the eccentric rods m are pivoted to the lower ends of the links 70.

The grain falls by gravity between the fluted plates and the grooved rolls, and the tailings are carried over the rolls, both grain and tailings being subjected to the action of the blast during their descent. The tailings fall into the tailings spout, and the grain slides down the gather-board K into the grain spout.

These grain cleaning devices are notherein more fully described as they are substantially the same as set forth in the patent hereinbefore referred to.

These grain cleaning devices, although sufficient for cleaning large grain such as Wheat or oats, are not sufficient to satisfactorily operate on very small seed such as timothy.

In order to clean timothy and. other small seeds, brackets 2 are secured to the top of the shoe N, one on each side. A frame 3 hasits rear end pivoted on the pins 4 projecting from the upper parts of the brackets 2. The front end of the frame 3 is supported on the upwardly and forwardly inclined guides 5 which are secured to the casing B, but which may be secured to the side plates 0. The frame 3 rests in a downwardly and rearwardly inclined position, and carries a screen 6 of perforated metal. The screen 6 has very small perforations all over it except upon two bands 8 and 9 which extend across it at those points where the material falls from the fluted plate dand the upperrollerb. Thesebandsareleftimperforate, as if perforations were made through them the material falling on them would catch in the perforations and accumulate at these points and interfere with the proper action of the screen. Short guide boards 10, 11 and 12 project downwardly and forwardly, on the under side of the screen, from the front edges of the bands 8 and 9 and the end of the screen. WVire teeth 13 project rearwardly from the end of the frame 3, for the purpose of carrying large rubbish over the tailings spout and deposit it on the rear part of the shoe N. A second frame 15 has its front end pivoted to the lower parts of the brackets 2 by the pins 16. The frame 15 extends under the frame 3, between the second and third grain plates E and G, and its front end is supported on the forwardlyand upwardly inclined guides 17 secured to the casing B, or to the side plates 0. The frame 15 carries a finishing screen 18 of finely perforated metal, and an imperforate plate 19 at its front end beyond the screen 18. A gatherboard 20 is secured to the under side of the rear part of the frame 3, and is inclined downwardly and forwardly over the screen 18. An adjustable guide board 21 is pivoted to the pins 4, and is inclined downwardly and forwardly so as to discharge all the material that falls between the wire teeth 13 into the tailings spout. Slotted arms 22 are secured to the under side of the board, and 23 are thumb screws for connecting the arms 22 to the brackets 2 after the inclination of the board 21 has been adjusted. The material which falls through the perforations of the upper screen 6, slides off the guide boards 10, 11 and 12, and the gatherboard 20, onto the imperforate plate 19.

The shaking motion of the shoe 1 is communicated t0 the two frames 3 and 15, together with a tossing movement caused by the inclined guides n, 5 and 17, and these combined movements cause all the material to be worked gradually across the screens in the said frames from the front to the rear.

The material discharged on the plate 19 passes over the screen 18. The clean seeds fall through the perforations of the screen, and slide down the gatherboard K into the grain spout. The rubbish which will not pass through the screen 18 is worked rearwardly over the end of the frame 15 and falls into the tailings spout.

What I claim is- 1. The combination, with the grain cleaning devices of a separator, provided with a shoe arranged above and to the rear of the tailings spout, and driving devices operating to shake and toss the said shoe; of brackets secured to the said shoe, removable upper and lower frames provided with screens and having their rear ends pivoted to the said brackets, supports for the front ends of the said frames, and an inclined gatherboard secured to the under side of the upper frame and operating to guide the material which falls through the upper screen to the front end of the lower screen, substantially as set forth.

'2. The combination, with a shaking shoe, such as N; of the brackets secured thereto, the upper and lower frames provided with screens and having their rear ends pivoted to the said brackets, supports for the front ends of the said frames, and a gatherboard arranged between the frames, substantially as set forth.

3. The combination, with a shaking shoe, such as N, and the upwardly and rearwardly inclined guides supporting it; of brackets secured to the said shoe, a frame provided with a screen and having its rear end pivoted to the said brackets, and upwardly and forwardly inclined guides supporting the front end of the said frame, substantially as set forth.

4. The combination, with a shaking shoe, such as N; of the brackets secured thereto; the upper frame pivoted at its rear end to the said brackets and provided with a screen, a gatherboard under the screen, and wire teeth projecting from its rear end; and the inclined guide board supported by the said brackets, under the said wire teeth, and operating to discharge the material which falls between the teeth into the tailings spout, substantially as set forth.

5. The combination, with an inclined guide board, and a revoluble cleaning roll j ournaled behind its rear edge; of a shaking frame, and a perforated screen carried by the said frame and having two imperforate bands 8 and 9 extending across it at those points where the material falls on its surface from the said guide board and roll, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
