JAMES E. KIMBLE, OF VIGKSBURG, MICHIGAN.
GRAiN-CLEANER FOR THRASHlN G-MACHINES.
FEPECIEICATION forming part of Letters Patent No. 337,502. dated March 9, 1886.
Application filed July 11, 1884. Renewed August 15, 1885.
To all whom it may concern.-
Be it known that I, JAMES E. KIMBLE, a citizen of the United States, residing at Vicksburg, county of Kalamazoo, State of Michigan, have invented a new and useful Grain- Cleaner for Thrashing-Machines, of which the following is a specification.
My invention consists in certain improvements, hereinafter described and claimed, in tended to simplify the construction and facilitate the operation.
In the drawings, forming a part of this specification, Figure 1 is a side elevation of a port-i011 of a thrashing-machine, parts being broken away and in section, showing the grain-cleaner connected. Fig. 2 shows details of the cleaner in enlarged perspective, and Fig. 3 is a cross-section near the bars 1' r.
The grain-riddle through which the. grain is sifted from the straw is shown at v, in the rear end of a thrashing-machine frame, B. This riddle is provided with grain-boards D D, beneath, inclining from each end downward and centrally, where an opening is pro vided for the passage of the grain onto the screen or sieve It below. This riddle is adapt ed to oscillate endwise in the manner common with said devices in thrashing-machines.
The screen-frame G is recessed around the edge to receive a screen, It, Figs. 2 and 3. Thus the screen rests detachably in the screenframe. The frame 0 is supported at the end nearestto the fan-wheel, Fig. 1, by supporting-rods pivotally connecting with the frame 0 and with the side walls of the machine. Below the screen h is aninclined grain-conveyer, P, its end nearest the fan-wheel loosely resting on the edge of the grain-box orlikestationary support. Between the ends ,of the screen It and conveyerP, which are the farthest from the fan, is a commonly-used construction, consistingofa rock-shaftprovided with the double levers f f, extending vertically in opposite directions from said shaft; butI have effected an improved and much-needed action of the screen and conveyer by a new construction and arrangement of these parts,as will appear in the description of the operation. The levers f f are pivotally connected with said ends of the screen and conveyer.
The rocking bar is provided with a cranklever, e,with the end of which the operatingbar t is pivotally connected, Fig. 2. The power-shaft is provided with a crank-disk, w,
Serial No. 174,517. (No model.)
with the slot of which the end of bar t is adjustably connected by a bolt to govern the movement of the rocking bar.
The frame 0 may be dispensed with and the parts f 1* connect directly with the screen h, if preferred.
The end of the frame 0 is provided with the straw-forks s s, which, as in other machines, are to prevent the straw from falling down with the tailings.
In the operation the screen and conveyer alternately oscillate endwise, as in prior devices; but as the mixed chaff and grain loads or thickens up on the screen at the end farthest from the fan, (the wind keeping it light at the other end with the assistance of the slight vertical movement given the screen by the circular sweep of the supporting-rods r 'r,) it is necessary to briskly toss the loaded end of the screen vertically, (instead of the other end, as in prior devices) which is done by the sweep of the rockshaft levers.
No vertical toss of the lower end ofthe conveyer, as in prior devices, is needed, for such action would retard the flow of the grain down its incline, whereas a vertical toss of the conveyer at the upper end where it loads up the heaviest is necessary to facilitate the downward flow of the grain, which action is efl'ected by my construction and improved arrangement of parts.
Having thus described my invention, what I claim as new is The combination of a fan-mill case, ascreen, supportingrods pivotally connecting said screen and the walls ofthe case at the end ofthe screen nearest the fan, a grain-conveyer having its end nearest the fan loosely resting on a stationary support, and the double-levered shaft having its lever-arms connected with and supporting the end of the screen and conveyer farthest from the fan, whereby the vertical action described of each of the ends of the horizontally-oscillating screen and the elevated end of the conveyer is effected, substantially as set forth.
In testimony of the foregoing I have hereunto subscribed my name in the presence of two witnesses.
JOHN H. GHAsE, J. S. DUER.
