WILLIAM SIMMONS JUDD, OF SAN DIEGO, CALIFORNIA, ASSIGNOR OF ONE- HALF TO FLETCHER EMLEY, OF MUNGIE, INDIANA.

BAND-CUTTER AND FEEDER FOR THRASHING-MACHINES.

SPECIFICATION forming part of Letters-Patent No. 510,061, dated May 28, 1895.

Application filed $eptemher6,1894. Serial 110,622,292. (No model.)

My invention relates to band cutters and.

feeders for thrashing machines, and is designed as an improvement upon the invention described and claimed in Letters Patent granted tome April 14, 1885, No. 315,948.

The object of the present invention is to improve the device set forth in said patent whereby superior advantages are obtained with respect to simplicity of construction and efficiency of operation.

v The invention consists in the novel construction and combination of parts hereinafter fully described and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of a feeding and band-cutting attachment for thrashing-machines constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view on the line 00 00, Fig. 1. Fig. 3 is a side elevation of the apparatus. Fig. 4 is a detail view of the eccentric forelevatingandloweringthespreaders. Fig. 5 is a bottom View of the adjustable feed-ta ble. Figs. 6 and 7 are detail views.

In the said drawings, the reference-letter A designates the frame of the device, which consists of a bottom B,side-beams O O, and crossbeams D D, and rearwardly extending sides D, D, supported by uprights D D and diagonal bars D D E,E, designate inclined guide boards secured to the side beams of the frame.

The letter I-I designates a detachable center-board which is provided at its front end with lugs I, I, which engage with openings in a transverse beam K. The rear lower end of the said center-board is provided with books L, L, adapted to be connected with the rear beam 1). When sheaves are fed to the machine it is proposed to use the said centerboard on each side of which a sheaf may be fed, and when loose grain is fed the said centerboard is removed, as in my said patent before referred to. r

P, and Q, designate shafts journaled trans-' versely under the frame at the front and rear ends and are provided with rollers R, R, having transverse slots M, M, therein to receive the slats of the carrier, as hereinafter fully set forth. These rollers are connected by means of sprocket chains N, N, engaging with sprockets N, N, on said rollers and connected with the sprocket chains are transverse slats N N which when covered with canvas or other material form the grain carrier.

Just in rear of the shaft Q is a transverse shaft S which carries a driving wheel T, a driv ing pulley V, and a pinion V meshing with acog-wheel W on the shaft Q, by which the latter is rotated.

Pivoted in the diagonal barsD D are rearwardly extending arms X, carrying at their free ends a shaft Y, having a roller Y extending transversely across the apparatus. This roller is provided with a number of teeth Z projecting from its periphery and is adapted to rest by gravity upon the grain being fed to the thrasher, and prevent it from being drawn into the concave too rapidly. Secured to one end of shaft Y is a pulley Y connected by means of a belt Y with a pulley Y upon a short shaft Y journaled in one of the diagonal bars D and provided with another pulley Y, which is connected with the drivingshaft S by means of belt Y Secured to the opposite end of shaft S, is an eccentric disk A connected by a rod or pitman A with a crank A on one end of a shaft A mounted transversely upon the upper part of the frame,

mounted upon a pin B journaled in the sleeve B and extendingfthrough the frame beam B". The lower end of the sleeve 13, carries arearwardly extending bifurcated plate 0', having ICO of downwardly extending stirrers D ,asin my patent above referred to.

Connected with the diagonal bars D D and the side beams O, O, are upwardly extending outwardly inclined side flanges F, F, the objectof which is to prevent any spreading grain from escaping at the sides of the device and allow it to be readily conveyed by the carrier to the thrashing machine.

The feed table is made in two boards or parts F, F with metallic covering plates F the former of which extends beyond the board F and overlaps plate F The board F is secured to the side pieces 0 O by means of brackets F which are pivoted to plates F secured to board F. Secured to the under side of board F, are downwardly depending screwrods F provided with nuts F These rods pass through slots F in forwardly extending arms F secured to the under side of the board F By unscrewing the nuts F the feed-boards may be adjusted so that the concave of the thrasher may be raised or lowerod without changing the adjustment of the feeder.

By the construction of rollers R with transverse slots M, the carrier slats in their movement will fall into these slots and be flush with the periphery of the rollers, thus allowing the feed-table to be placed in close proximity thereto and preventing any grain or trash from being knocked back under the machine by said slats. These slats must be so arranged relatively to the grooves that they will register therewith at the proper times, so as to be received thereby.

Having thus described my invention, what I claim isn p In a band cutter and feeder for thrashing machines the combination with the frame, the brackets secured thereto, the stationary feedboard having plates pivoted to said brackets, and the pins secured to said board, of the adjustable feed-board, the arms secured thereto having slots at their inner ends through which said pins pass, the screw-nuts engaging with said pins and the metal plates secured to said boards and overlapping each other; substantially as described.

In testimonythat I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

WILLIAM SIMMONS JUDD.
