GRAIN-SEPARATO'R.

SPECIFICATION forming part of Letters Patent No. 469,827, dated March 1, 1892. Application led November 10, 1891. Serial No. 411,470. (No model.)

To a/ZZ whom t may concern.'

Be it known that I, WILLIAM H. ScHULTE, a citizen of the United States, residing at H opedale, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in GrainSeparators; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will en'able others skilled in the art tov which it appertains to Amake and use the same.

The invention relates to grain-separators which have rotary wire screens, such a one being described in Patent No. 215,078, granted to Sturgeon on the 6th of May, 1879.

My invention consists of the particular means by which I raise or lower one end of the screen-shaft, so as to regulate the inclination of the screen to suit the grain or seed which is to be separated; also, the particular means which are employed by me to jar or shake the reel when so desired.

Figure l of the drawings isa vertical longitudinal section of the separator; Fig. 2, a detail vertical sectional view of the device for raising or lowering the discharge end of the reel or screen shaft. Fig.3 is a detail view of the hand-piece, together with its connections, which are in section; Fig. 4, a detail side elevation of the knocker and the strip against which it turns, and Fig. 5 a detail view of the shaft and showing the annular groove therein.

In the drawings, A represents the discharge end of the case, slotted at a to allow the flat part b of the handpiece B to pass therethrough, as it also passes through the slot c of an outside plate C, which is made fast to case end A. On this plate C is made a rack or series of notches on each side of the slot c. The piece B has a tubular portion b', Whose shoulders abut against plate C, while through the tube extends a rod D, which has a {ingerdisk d on the outside end and a cross-pin d on the inner end. Around the rod and between its ends is arranged a spiral spring E, which holds the cross -pin in the rack or notches 011 plateC. On the inner end of the hand-piece B is secured a vertical slide F, which is moved in the guides G G on the case end A. At the top of this slide is an open bearing to receive one journal of the screen-shaft H. When it is desired to change the inclination of the screen, one inger is pressed on the disk d,while the slide F is carried up or down to make the adjustment. The spring on rodD will then draw the crosspin d in the opposite grooves of plate C and thus hold the slide securely.

On the shaft H, near the hopper, I place a polygonal disk to turn With the shaft against the strip J. As the polygon I turns it jars the screen, so as to dislodge the seeds which may stick vin the interstices of the wire reel, the shaft H risingin the slot a. The knocker may or may not be used, as the shaft H has a groove h.

'Vhen itis desired to use the knocker, move the hopper end or the elevated end of shaft up to the polygonal disk, when the latter will strike or jar the reel or screen. The shaftgroove h receives the bearing of slide F, or the screen, which is always on an incline, would slip back. The wire screen is made somewhat shorter than the inside of the case, which allows the higher end of the reel to be moved up, so as to be locked on the bearing of slide F. Without making the groove h in the shaftI could not use the knocker; but with it I can operate the knocker or not, as circumstances make it expedient or otherwise. I have, however, tested the whole invention in av full-sized grain-separator, and both features thereof have been found to work Well. Hence I have deemed it but right that I should obtain protection under the patent law for what must inure to the benefit of the public.

Having thus described all that is necessary to a full understanding of my invention,what I claim as new, and desire to protect by Letters Patent, is-

In a grain-separator, the combination, with the end A, having the vertical slot a, of the hand-piece B, flat at b and tubular at '11', the outside plate C, having slot c and notches on each side thereof, the rod D, having a disk d at one end and a cross-pin d at the other, the spiral spring E around said rod, and the slide F, having an open bearing at the top, all

substantially as shown, and for the purpose specified.

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

WILLIAM H. SCHULTE. Witnesses:
