IMPROVEMENT IN GRAIN-SEPARATORS.
Specitication forming part of Letters Patent N o. 116,549, dated July 4, 1871 autedatcd June 22, 1871.
[o Il yuff/1.0m fit. ymay concern:
Be it known that I, JOHN l). BRUNNIGR, of Doylestown, in the county otl Bucks and in the State ot' Pennsylvania, have invented certain new and useful Improveinents i n Grain-Se}v)arator5 and do hereby declare thatthe follo win g is ai'ull, clear, and exact description thereof, reference being had to the acc(unpanying drawing and to the letters ot' reference marked thereon making part of this speciiication.
The nature of my invention consists in the construction and arrangement of a grain-se] arator, as will be hereinafter more tull y set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, reterring to the annexed drawing, in which- Figure l is a longitudinal vertical section, and Fig. L a plan view ot' my machine. Fig. 3 is aperspeetive vicwot' one or' the screens in the separator.
A reln'esents the trame otl my machine, in the upper rear end oi" which is the hopper B. This hopper is provided with two openings, (l, each having a lid, l), as shown. (l is the shoe containing the screens l) 1)', said shoe being suspended at the rear end by straps d d, and restin at or near the front end on a square shaft,1 or rather on a square jog, f, in the middle of the shaft E. Onv the under side ot' the shoe C is a ln'oiection, g, bea-ring against the rear side otl the jogf, so tha-t, when the slxat't E is revolved, by means ot' a crank at one end, or any other suitable means, the shoe will get two motions, up and down and endwise, which are very necessary to cause the grain to tiow down. The screensD D are placed in grooves in the sides ofthe shoe (1, and spouts /L la arranged at the front end of the shoe, as shown in Fig. 1,-carry the gjrain from said screens into diiierent compartments ot' the seed-box G. The screens are ot' ditterent iiueness, so as to be used for dit'erent seed, and they are arranged so that the grain on two ot' them ows faster than on the other two. This is accomplished by having` two of the screens hung or pivoted at their front ends to cleats 7c k, which cleats slide in the grooves on the shoe, so that the rear ends of said screens may be raised up. One ot' these two screens, 1)', is re1 )resented in Fie. 3. By this n1a chine .l can take the cockle Iand cheat all out of wheat, and, at the same time, separate the large grains of wheat from the small, having the large wheat to sow. :ly the proper arrangement of the t'our screens I can Iseparate all seeds and grains, itA mixed together. i
Havin thus fully described lnyiuvention, what I claim. as new and desire to secure by Letters Patent, is
The combination, in the grain-separator herein described, otA the screens 1)', provided with the cleats k, with the shoe C provided with the lug g and the shat't E, when all these parts are constructed and arranged as shown and described, for the purposes set forth.
In testimony that I claim the ioregoing I have hereunto set my hand this 23d day of November,
JOI-IN D. BR'UNNER. Vitnesses:
