'UNITED STATES PATENT OFFICE.
THOMAS H. DRURY, OF VHEATLAND, OREGON.
IMPROVEMENT IN ROTARY WINNOWERS.
Speciiication forming part of Let-ters Patent No. 146,993, dated February 3, 1874; application filed June 11,1873.
To all whom. it may concern:
Be it known that l, TnoMAs H. DRURY, of Vheatland, Yamhill county, Oregon, have i11- vented certain Improvements in Grain-Separators, of which the following is a specification:
Flgurel is a perspective vlew, and Fig. 2 a vertical longitudinal section, of a machine eml; o `lyin g my improvement.
The object of my invention is the complete sepa rati on of wheat from other gra-ins admixed with it by growth from. the eld or otherwise.
The machine consists, in a general manner, of
vprojecting interior hopper in that end of the screen C, as by revolving the screen O, such impurities, being lighter than the grain, rise to the top, when the screen is partially filled, and are caught by the hoppers l) and thrown over the partition B. The grain is first i11- rroduced into the high hopper E at the opposite end to the one just described. Un-
der the hopper' E is an inclined perforated metal screen, F7 which, with the hopperE, rests .on four spiral springs, G. Under the screen F a receptacle or second hopper, H, is placed.
Into this the hollow end of the revolving screen O is introduced. This hollow part also forms the bearing for this end of the screen O. Inside of this hollow part a worm, I, is placed, to feed from H into O. To the under side ol' the high hopper E is attached a projecting pin, J, against which the cams or lifters K strike in succession as they are revolved, lifting` E and F with a kind of jarring motion. Just between the strokes of K a lateral motion is given to E and F by the lever L impinging against the pins M in the end of screen C. The npper end of this lever L is made into a kind of ot' fork, in which the pin J rests, this being acted upon by the cams K and the pins M alternately, thereby giving a double motion to the hopper' E and the screen F, which is most conducive to turn the grain through the holes in the screen F. The opposite end of C is merely furnished with a crank and the small conical-shaped hoppers D, before described.
The parts claimed in the improvement consist of the high hopper E and metal screen F, to which a jarring motion is given, as before described, by the pins M and cams K, by the action of the lever L and its spring N, which tpushes its lower ends against the pins M.
I claim- The hopper E, screen F, and pin J, in combination with lifters K, lever L, and pins M,
arranged to operate substantially as and for the purpose specified.
