UNTTED STATES JOHN PARNELL, OF GRAYSON, CALIFORNIA.

TRAVELING THRASHER.

SPECIFICATION forming part of Letters Patent No. 366,242, dated July 12, 1887.

Application filed December'flf), 1884. Serial No, 151,406, (No model.)

To aZZ whom it may concern/.-

Be it known that 1', JOHN PARNELL, a citizen of the United States, residing at Grayson, in the county of Stanislaus and State of California, have invented certain new and useful Improvements in Traveling Thrashers, of

that class in which by one continuous opera tion the grain is cut, conveyed, thrashed, and sacked; and my invention consists in the con struction and combination of parts, which will be more fully described hereinafter, and pointed out in the claims.

Figure 1 is a side elevation of the same, partly in section, and showing the side of the hopper broken away. Figs. 2, 3, 4, 5, 6 are detail views of the different parts.

As my invention relates entirely to the shoe and conveyer, no other portions of the thrasher are specially shown and described.

A B are the driving and carrying wheels, mounted in the frame-timbers in the usual manner.

A are internal gear-whee1s, (only one of which is here shown,) suitably fastened to the spokes of the wheels A B, and engaging with two or more master-pinions, A whose shafts, connecting with and actuating a series of gearing, shafting, and pulleys, furnish the power which drives the internal and external machinery of the thrasher.

G is the shoe containing the usual sets of sieves, being hung looselyby the swinging ver tical side rods or chains, from the crosshead supported on the trunk F of the thrasher. Extending forwardly from the cross head 0, and through the horizontal pipe 0 is the rod 0, which is connected to the crosshead at one end, and has its other end turned downward and a weight, 0', secured to it. This weight 0 serves to balance the rod at its forward end, so as to always hold it in position. The pipe 0 is supported at its center by a holder, D, secured to the trunk F, and.

attached to this pipe is a side balancing rightangle lever, D, which is provided with the weight d at its lower end. This angle-lever D moves freely in the holder D, and serves to keep the pipe 0' in a horizontal position. Any inclination of the pipe 0 or rod 0 to tilt toward either end is at once checked by the weight d on the lower end of the right-angled lever D. The holder D being attached to the roof of the trunk F, the pipe G has free room outside and over the trunk F to perform its required motions, and the right-angle leverD also has space to vibrate at the side of the trunk F, the weights 0 and (Z at the respective ends of the rod 0 and lover D always maintaining them at a level, and therefore maintains the surface of the shoe at a level, no matter how much the machine itself may sway in passing over rough ground.

To the front of the shoe 0 a shaking device is attached, consisting of a cross-rod, P,which is mounted upon the inside of the trunk Fin front of the shoe, and having posts P carrying loosely mounted thereon cross-bar P and from which extends rearwardly a lug, P, engaging with the'shoe, as shown in Fig. 3. A post, P, mounted on the rod 1?, engages with a shaft, R, attached by its eccentric-head to a crossshaft, R, which may be connected to any operating-belt of the machine, and thereby impart an end shake to the shoe. The tailings rejected by the screens of the shoe are conveyed back to the cylinder by a trough composed of the rear section, S, containing the conveyer S, and the top section, S,which contains a sieve, s,whereby a large portion of the shelled grain is separated from the tailings.

and the grain dropped down a tube, S upon a grain-carrier back of the cylinder. Asmall fender, s, in front of the sieve 8 serves to turn the course of the shelled graiifpassing said sieve down the tube S. The residue ofthe tailings is discharged through a trough-section, s and deposited in front of the cylinder.

Having thus described my invention,I

claim 1. The combination of the shoe 0, chains 0, cross-bar G and rock-lever G the rod P, provided with posts P P, the bar P, provided ver D, provided with the weight (2, and holder with the lug P, the rod R, and the operating D, substantially as shown.

shaft R, by means of which. the shoe is rocked, In testimony whereof I affix my signature substantially as described. in presence of two witnesses.

2. The combination, with the shoe 0, the JOHN PARNELL. chains 0', the pipe 0 the cross-head C, the lever-arm O, passing through the pipe 0 and provided with weights 0 at its end, angle-1e- \Vitnesses:
