SPECIFIQATION forming part of Letters Patent No. 398,197, dated February 19, 1889.

Application file September 11, 1888. Serial No. 285,133. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. UNDERWOOD, of Lamoure, in the county of Lamoure and Territory of Dakota, have invented. certain new and useful Improvements in Band-Gutters and Feeders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to an improvement in thrashing-machine feeders and band-cutters;

and it consists in the combination of the crank-shaft, a connecting-rod, a cranked rod which has a vibrating movement, a frame which moves horizontally back and forth across the end of the frame where the bundles are fed in, and a pivoted double-acting rake which moves back and forth with the frame and which draws the bundles upon the endless carrier from first one side of the frame and then the other, all of which will be more fully described hereinafter.

The object of my invention is to provide a machine into which the bundles may be fed from opposite sides and these bundles alternately raked upon the endless carrier which moves them toward the thrashing-machine, and which bundles have their hands out by 3 revolving cutters, and then the straw evenly divided upon the end of the endless carrier before being fed into the thrashing-machino.

Figures 1 and 2 are side elevations taken from opposite sides. Fig. 3 is an end view. Fig. 4 is a plan view, the covers being removed. Figs. 5 and 6 are detail views. Fig. 7 is a longitudinal vertical section.

A represents a thrashing-machine, of any suitable construction, to which the frame B is secured in any suitable manner. The manner of attaching the frame B to the thrashingmachine will be varied according to the 5 make of the thrasher. As here shown, the

frame B has the extensions C, which project horizontally beyond its ends and which catch upon the thrasher and support the frame B in a horizontal position. Placed upon the shaft of the thrasher-cylinder is the pulleyD, around which the endless belt E is passed. 1

This belt E passes outward from the pulley D, around the two idler-pulleys F, WhIOh EtIG journaled upon the frame of the thrashing machine and around the pulley G upon the shaft l-I, upon which the rotary disks I are secured. Each one of these disks has a kmfe projecting from its side, and the knives on alternate disks project from opposite edges of the disks, so as to make sure that as the disks revolve the knives will cut the bands upon the bundles as they rest upon the endless carrier J and are being moved toward the thrashing-machine. The frame B 1s provided with vertical openings or guides upon both of its sides where the shaft H passes through, so that the cutters can be raised and lowered according to the size of the bundles.

To the opposite end of the shaft H from the pulley G is a pinion, K, which meshes 7o with the spur-wheel L. This spur-wheel must also be made adjustable by means of its box or bearing with the shaft H, so that the pmion and wheel, will always mesh together. Upon the hub of the wheel L is a sprocketpinion, N, around which the chain 0 passes to the sprocket-wheel P. This wheel can be thrown in and out of gear by'means of the lever Q with the shaft upon which it is placed,

so that the parts of the band-carrier can be stopped and started whenever so desired. Another reason for throwing this wheel in and out of gear is that the band-carrier should never be stopped or started except while the thrashing-machine is running at full speed.

5 -The-wheel P is placed upon the shaft R,

which is provided with a pinion, S, and a roller for moving the endless carrier J.

The pinion S meshes with the spur-wheel '1, which is placed upon the crank-shaft U, which ex-' 0 tends across under the frame B and is provided with a sprocket-wheel, V, at its opposite end. From this sprocket-wheel V the sprocket-chain XV extends up over a sprocketpinion, X, upon the shaft R, to which the beat- 5 ers Y are secured. These heaters Y all run at a much higher rate of speed than the endless carrier J and break up the bundles and f scatter the straw evenly upon the carrier J 1 before it is presented to the thrashing-cylm- IOO der. The disks I revolve at a much higher rate of speed than the heaters Y, because the port for the rake 1).

knives must revolve with sufficient rapidity to make absolutely su re that every band will be cut.

Connected to the crank-shaft U is the connecting-rod Z,which is connected at its outer end to the partially-rotating shaft A, which is provided with a crank at each of its ends. The crank at the lower end of this shaft A is just long enough to cause the upper and longer crank, 13, to vibrate back and forth across the outer end of the endless carrier J for the purpose of moving the horizontally moving frame C and operating the pivoted rake D, which is journaled therein.

The frame 0' is a rectangular frame, which moves back and forth in suitable guides prepared for it, and which serves simply as a suplo this frame C are secured two cross-bars, I, under which the chain, wire, or cord F, secured to the end of the crank B, passes. The outer ends of this rope, wire, orchain are secured to cross-bars i of the rake 1). Each end of the rakeframe D is provided with vertical rake-teeth, which arealternately raised and lowered for the purpose of moving the bundles which are thrown upon the end of the frame B inward upon the outer end of the endless carrier J.

The frame B is provided with the hinged platforms or doors H at each side, and these doors are supported in a horizontalposition when open by means ofsuitable chains. The bundles being thrown upon these doors or platforms H, the crank 3 first moves the frame C and rake D toward one side, and as the rake and frame advance toward that side the teeth of the rake at that end are raised, so as to pass over the top of any bundles which have been thrown upon the platform. At the same time that the teeth of the rake are being raised at one end, at the opposite end the teeth are descendin g, so as to catch 1 he bundles which have been thrown upon the door I1 and frame B on the opposite side and move them upon the end of the endless apron. Thus, as the rake advances toward one side, it moves the bundles upon the end of the endless apron upon the opposite side. As the endless apron moves toward the thrashin g-cylinder, the bundles are moved under the revolving knives to have their bands cut. \Vh e11 the machine is not in use, the doors H are raised into a vertical 130- sition and a cover is lowered so as to cover over the top of the reciprocating frame and rake, and thus protect the parts from the weather. A similar cover is also provided for covering over the inner end of the frame, the endless carrier, and thrasher.

As the frame B and its attachments are connected to the outer side of the thrashcr and extend a considerable distance beyond it, it becomes necessary to lengthen the tongue, so that the frame can be fastened to the thrasher to move it about. For this purpose a splice, L, is secured tothe front axle, M, and extends outward any suitable distance, and this splice is made in the shape of an inverted U. Into the under side of this splice the tongue is inserted and secured at any desired point.

Of course if the frameB is not to be moved around with the thrashing-maeh-ine, then there willbe no need of extending the tongue beyond the splice.

Having thus described my invention, I elaim 1. The combination of the crank-shaft U,

connecting-rod Z, partially-rotating shaft A,

provided with a crank at each of its ends, an endwise-moving frame operated by the'shaft, and a pivoted rake which is carried by the frame and also operated by the shaft, substantially as shown.

2. The combination of an endless carrier or apron, an endwise moving frame which is made toreciprocate over the outer end of the carrier, a pivotal double-ended rake placed in. and carried by the frame, an operating-crank, chains for connecting the ends of the rake to the crank, and an operating mechanism, substantially as described.

3. The combination of the frame B, the end-' less carrier, the endwise-moving frame, the
