JOHN C. SCHNEIDER, OF HUDSON, VVISUONSIN.

THRASHING-MACHlNE.

SfPECIFIGATION forming, part of Letters Patent No. 274,395, dated March 20, 1883. Application filed January 9, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN G. SCHNEIDER, of Hudson, in the county of St. Croix and State of Wisconsin, have invented certain new-and useful Improvements in Thrashing-lliachines and Ido hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom panyingdrawings, which form a part of this specification, and in which- Figure 1 is a longitudinal vertical sectional view ofmyimproved thrashing-machine. Fig. 2 is a top view of the separators. Fig. 3 is a vertical cross-section of the same. Fig. 4 is a detail top view of the pitmen operating the separators. Fig. 5 isadeta-il side view ofthe same; and Fig. 6 is a detail view, showing one of the endless screws feeding the grain to the discharge-chute and the nnthrashed ears to the elevator carrying it back to the cylinder.

The same letters of reference indicate the same or corresponding parts in all-the figures.

My invention has relation to thrashing-machines; and it consists in the improved coustrnction and combination of parts of the separating and discharging mechanisms,as will be hereinafter more fully described and claimed.

In the accompanying drawings, the letterA indicates the casing or frame of the machine,

' containing the several operative parts.

B is the feed-hopper through which the grain is fed to the thrashing-cylinder O and the beater D, which aids in beating the loose grain out of the straw as it passes under it to the separators. These separators consist of a series of long narrow screens, E, having longitudinal grooves F in their upper surface again are fastened to a oross-piece, N, and the cross-pieces H and N are operated by means of pitmen and arms in such a manner that the screens and the boards will have an alternating upward and rearward vibratory motion, by which the grain is shaken out of the straw, and the straw is at the same time carried rearward and out of the machine.

The pitmen and arms operating the screens and boards are shown in detail in Figs. 4 and 5, and consist of two pitmen, 0, connected at 7 patented in the thrashing-machine for which.

Letters Patent No. 267,599 were granted to myself and Hans Ghristofferson on the 14th of November, 188:5. The lower ends, S, of the arms Q extend beyond the pins R and rock in segmental plates Tupon theframe as the crankshaft revolves. Two spiral springs, U, are fast enedin the ends of the plate T, and bear with their free ends against the sides'of the end of the arm, cushioning its motion and taking up all jars. The pitmen O operate the screens, and similar pit-men,V, operate the boards L, in conjunction with the arms W, which are of the same construction as the pitmen, but pivoted upon pins X in the frame. The pitmen and crank-shaft operate the screens in the rear end of the machine, while the screens and boards are supported in the forward end of the machine by means of arms Yand Z, constructed and fastened in the same manner as the arms this shaft are placed sleeves 2', having aspiral -tlange,j, and a notch, 70, in one end and a projection, l, in the other end, which fits into the notch of the adjoining sleeve, the ends of the spiral flanges fitting to each other, so as to form one continuous flange. A nut, m, is screwed upon the other end of the shaft, inside the bearin g, clamping the sleeves between it and collar h, so as to hold them firmly. In this manner, it part of the conveyer is inj ured by accident or wear, one or two sleeves may be removed and replaced with new sleeves without the necessity of replacing the whole conveyor. A similar conveyer, n, is placed at the bottom of the rear end of the t'rame,-which conveys unthrashed heads and grain passed over the cleaner-screens to an elevator, 0,which carries it to an inclined board, 1), from which it falls into the feed-hopper and is thrashed again.

Having thus described myinvention, I claim and desire to. secure by Letters Patent of the United States- 1. In combination with the screens of a grain-separator, the crank-shaft P, pitmen O and V, and arms Q and W, substantially as shown and set forth.

2. The combination, with the screens in a grain-separator, of the crank-shaft P, pitmen O, armQ, pivoted at R, and having short end' S, segmental plate T, and spiral springs U U at both ends, bearing with their free ends against the end S of arm Q, as and for the purpose shown and set forth.

3. In a grain-separator for thrashing-m achines, the combination of the screens E, pivoted cross-pieces H, arms V, pitmen O and arms Q, pivoted boards L, placed edgewise,

alternating with screens E, arms Z, and pit- In testimony that I claim the foregoing as, my own I have hereunto affixed my signature in presence of two witnesses.
