BAND CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 296,695, dated April 8, 1884.

Application filed December 22, 1583. (No model.)

To aZ-Z whom it may concern.-

Be it known that I, MATTHEW H. J OSLYN, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Band Cutters and Feeders; and I do 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 appe'rtains to make and use the same, reference being had to the accompanying drawings, and t0 the letters and figures of reference marked thereon, which form a partof this specification.

My invention relates to improvements in band cutters and feeders for thrashing-machines.

It consists in the combination,with the cylinder and suitable feeding devices, of a graincasting platform made in sections, with its upper and lower sides hinged to the framing, and its middle portion movable to and from the cylinder. 7

' It consists, further, in the combination,with the cylinder and the-grain-casting platform, of the returning-belt arranged above the cylinder, and, adapted for use substantially as hereinafter specified.

It consists, further, in the combination,with the feeding-belt, of the separating-fingers and means, substantially as hereinafter described,

whereby said fingers may be adjusted to and I from the feeding-belt.

It consists, further, in other improvements,

all of which will be hereinafter described and claimed.

In the drawings, Figure l is a side view of the forward portion of a thrashing-machine, the casing being partly broken away in order to better illustrate the interior construction. Fig. 2 is a front elevation of the machine. Fig. 3 is an elevation of the forward portion of the machine on the side opposite that shown in Fig.1. Fig. 4 is a detached view from overhead, indicated by arrow a: in Fig. 1. Fig. 5 is an enlarged detail view, illustrating one of the spreading-fingers, all of which will be described. I v

The casing is of ordinary construction. In the upper forward end of the casing I arrange the feed belt A,journaled on shafts A A.

This belt is arranged in ahorizontal plane, and its outer end is projected beyond the easing in position to receive the straw as it is fed into the machine. A shaft, A is journaled above the feed-belt about midway of its ends, and is provided with a series of band-cutting disks, A A bar, B, is secured in the casing above and slightly in advance of the inner end of .belt A. To this bar I pivot the arms 0, which are connected together by a rod, 0, which is pivotally secured to each of arms 0 about midway of their lengths, as most clearly shown in Fig. 4. Fingers D are pivoted at their upper ends to the arms (1, and their opposite ends are curved, as shown, and extend ed down in position to engage the grain and spread the latter as it is delivered from the inner end of the belt A. A slot, D, is formed in one side of the fingers D. This slot is formed square at one end, and its other end is provided on its outer edge with an ear, Dflwhich forms a notch, D in the end of the slot. The portion of the finger in front of the slot is threaded, as shown at E. A collar, E, is placed on the finger next slot D, and is provided with a lug, E, projected forward over the slot D and opposite ear D Anut, F, turns on threaded portion E of the finger and up against collar E, as shown.

A segmental bar, G, is secured to the rock ing arms 0, and is curved on an arc struck after the band is cut will suffice to properly spread the bundle over the belt. In thrashing such grain I set the fingers high, so they will only .give the light stroke required. On the other hand,'when the bundle is heavy, either from the weight of the grain or from dampness of the straw under the band, or when the bundle is more closely compacted than usual and does not readily separate, the fingers are set so they will extend closer to the carrier and any desired point of adjustment by means different from those described. For instance, instead of the sleeve and nut, a set-screw might be arranged to turn through the fingersand bear against the segment, so that the finger may be clamped at any point thereon.

The graimcasting platform H is composed of boards or sections H H H and is hinged at its upper and lower ends, I I, to the framing. Thelower and middle sections are hinged together, and the upper and middle sections are connected by rod J and sleeve J.

extends into sleeve J, which is secured on the rear side of section H as most clearly shown in Figs. 1 and2. This permits the vertical movement of the said sections along each other, and yet prevents their detachment and retains them at all times in parallel planes and close together, whether in the position shown in full lines or in that indicated in dotted lines, Fig. 1. In order to give this platform H the desired motion, I employ thepitman K, secured at one end to the upper edge of section H, and

extended forward, with its other end journaled on a crank, K, formed on a shaft, K journaled in the framing. As this shaft is revolved the pitman K is given areciprocating motion, causing the platform to be thrown forward and back, asindicated in Fig. 1.

The thrashing-cylinder L is arranged in front of the lower end of the platform H. A

returning-belt, M, is supported. on rollers M above and slightly in advance of the cylinder. The upper end of this belt is inclinedforward, as shown. ,3

A bar, N, is secured under the inner end of the feed-belt and in front of the upper end of the platform H. Fingers. N are pivotedat one endto the bar N, and extended horizontally through slots formed in the platformH. For convenience of reference, I term these fingers the lower spreader-fingers, and the fingers D the upper spreader-fingers. The fingers. N are connected by a bar, 1W, which is connected by asuitable pitman with a crank, 0, formed on thelower end of ashaft, O. The upper end of this shaft is provided with a crank-pin, 0 on which I secure the pitman O, which operates the rod 0. Thus as the shaft 0 is revolved the upper and lower fingers are simultaneously operated. I have clearly shown the connecting belts, pulleys, &c., whereby the several parts of my machine are driven.- These do not form a part of my invention, and I have not thought it necessary to describe them in detail. It is obvious they may be varied in numerous ways with-out departing from the principles of my invention.

It is obvious that many modifications may be made in the form, 8m. of some of the partssuch, for instance, as platform H-without departing from the principles of my invention.

The rod J is secured to the rear side of section H, and

In this platform it is desirable to throw it forward at itsmiddle portion, so that the grain will be thrown up toward the belt M. It will be appreciated that this may be effected by arranging the upper or lower end of the platform so they may slide vertically in guides, instead of using sleeve J and rod J, as before described, though I prefer this latter construction, as thereby a simple, easy connection is formed, and one which will not, under any ordinary circumstances, become clogged in the operation of the machine.

' In operation the bundles of grain are placed on the feed-belt, and carried thereby past the disks A which cut the bands, and the grain is delivered over the inner end of the feedbelt, at which point it is caught and separated by the upper spreaders. It then fallsvertically onto the platform H, being further sep arated in its passage by the lower spreaders.

The platform H is pivoted or hinged at both upper and lower ends, and is forcedinward at the middle. Thisthrows the grain on the said platform up against the belt M. Itis caught by the beltM and returned downward, as will be readily understood. This prevents the straw from becoming massed in the corner of the casing occupied by belt M, and facilitates the return thereof to the cylinder. By the construction described the grain is thoroughly agitated and separated before it passes into the cylinder.

I do not desire to be limited to the particular means. shown for operating the grain-casting platform, nor to that for operating the spreader-fingers, as various modifications. or changes might be effected therein without departing from the principles of my invention.

It will be seen that, instead of hinging the platform at both ends and making it in section, it may be hinged at its upper end alone and operated at its lower end, so as to throw the grain upward. Such construction would avoid the necessity of making the platform in sections, and would effect the upward throw of the grain and prevent the straw from getting back of the upper end of the platform. I, however, prefer the construction shown and before described. In operation it will be seen that long grain passing over the feed-belt will be engaged by the return-belt M, and depressed at its ends to the cylinder. In this case good results will be had without the use of a grain-casting platform, though such platform is preferred, for the reasons before stated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
