v y, llwlPRovEMfzNT IN HARVESTERS.

Specification forming'part of Letters Patent No. l 55,8 l0, dated October 13, 1874; application led February 1c, 1874.Y

To all whom it may concern:

`. Avesters which are made with an inclined lateral extension of .thefplatforim up which the grain is carriedand delivered to the hands of a. riding binder.

In the accompanying drawing, which Vforms a part-of this specification, Figure l is a plan viewof the harvester'tted with my improvement. Fig. 2 is a front view of the same. Fig. 3 is a View of one of the rakes isolated from the other parts, showing the means of attachment to the carrier-chain. Fig. 4 is a side view of said attachment. Fig. 5 isa section across the carrier-chain and adjacent parts. Fig. 6 is an end elevation of my machine, showing portions broken away to display interior construction. Fig. 7 is an elevation of the chain-guide roller-frame.

Like letters of reference in all the figures designate like parts.

In the said drawings, A A is the platform, consisting of the horizontal portion Aand the inclined portion A. B is the sickle, and O the receptacle for the grain at the binders hand. In` a suitable inclosed frame-work, D, lat the back of the platform are mounted the pulleys or rag-wheels E Ef, over which passes the endless chain F, encountering the guide-rollers e at the bend or turn from the horizontal to the incline of the platform, and also the pressure-rollers e', mounted in a spring-frame, j', which latter, bearing upon the chain, serves to keep it at the proper tension, and allow the rake-connections to pass under them between them and the chain. The frame-Work D consists of an inclosure or box, the face of which is cut by a continuous groove, d, opposite the chain, throughout its length. Upon the edges of this groove run the train-wheels t' of the small carriage G, to which is hinged the end of the rake H. A ange upon the wheels i prevents them from escaping from the groove.

The course of the chain is indicated by the ar-l rows. The carriage G, to which is hinged the rake, is made curved at one side to allow it to pass around the guard-rim J at the lower pulley or rag wheel E. The upper portion of the groovercl has affixed to the plate D', between the two portions (upper and lower) of the said groove, a cam, K, of al trough shape, (shown in section at Fig. 5,) extending from one to the other Aof the rag-wheels E E, and having each end lrounded off, so as to take gradually under the end of the rake, and raise it as it passes back along the upper groove, so that it may loe out of the way of the reel, which is not shown. The carriage G, to which the rake is pivoted by the arms l and pivot j, is broad enough' to bear upon the case D D at each side of the groove, being wholly outside of said case, while the wheels i run within the groove itself, and their anges set against the inner face, `thus holding the carriage in place. The rakes M M consist simply of a single bar, m, hinged, as stated, to the carriage, and furnished with the teeth n. There may be any number of these rakes desired, but two will ordinarily be sufficient. The rake M, which is shown traversing the platform, lies horizontal, with the teeth down, while the rake M, which is upon the upper ply of the chain, and consequently on its return trip, is elevated nearly to the perpendicular, with its teeth upward. Just 4above the grain-receptacle C is placed a comb, l?, which clears the rakes of all grain as they pass. The grain, falling upon the horizontal portion-0f the platform, is swept up the incline and into the receptacle C. The rake, having performed this duty, returns by way of the upper portion of the groove, and repeats it.

I am well aware that rakes have been heretofore carried backward and for-ward across a platform by means of an endless chain; and I therefore do not claim such, broadly.

The spring-frame f is made with a curve corresponding to the curve of the frame D, and in it are journaled two guide-wheels, e e', beneath which the chain F passes. Two guidewheels are employed to relieve the curve of the chain of that abruptness which it would have if it passed only one, and therefore the carriage G will pass the curve at that point more easily and with less liability to derangement than would otherwise be the case. At each end of the carriage f there is a guide-pin, f', and a tension-sprin g, so that it is kept properly down to its work without any jarring or tendency to displacement; .and therollers may be perfectly adjusted to equal pressure upon the chain F. The tongue I is pivoted at its rear end to the main frame at or near the main axle, and it is restrained from lateral motion by passing betweenftwo lugs or standards, t t, located on the front edge of the main frame. The drivers seat U is mounted upon the tongue T by means of' the leg u, so that the weight of the driver is supported by the main wheel at one end of the tongue, and by the yoke at the necks of the horses. An elbow-lever, V, pivoted at its elbow to the main frame, extends upward to a point conveniently within reach of the drivers hand. Its lower or short end extends forward by the side of the tongue, to which it is jointed by meansl of a pin, through a slot in said lever. With the seat and lever so arranged, the driver can, with ease, change the position of the front edge of the main frame without said change being influenced by the weight of the driver. The binders foot-board W is hinged at its inner edge to brackets fw, so that it may be turned up or folded out of the way while the machine is being transported from place to place. Its outer edge is supported by folding braces p. The binders tables' Y are hinged to rods y y, so that they may, whenrfolded down by the side of the frame, be slipped endwise, and be' entirely protected against the said frame. The outer edges of the binders tables Y are supported by hook-braces z when 1n use.

Having thus fully described my invention, that which I consider new, and desire to claim as my invention, is-

1. In combination with the horizontal and inclined platform A Al and the grooved casing standing at the back, provided with the cam-guide K, the endless chain Il, passing over rag-wheels E E', the guide-rollers e e', set in a single frame, f, and the rake-carriage Gr, substantially'as set forth.

2. The spring-framef, with pins f and tension-springs at each end, and provided with two guide-rollers,combined with the endless chain F and rake-carriage Gr.

3. The guide-cam K, combined with grooved frame D, and carriage Gr, and rake m, `jointed thereto, as set forth. Y

l .4. The 'carriage Gr, having the rake-arm hinged, and provided with flanged wheels t', in combination with the upper and lower edge of said cam-groove d, as set forth.

5. The binders table Y, hinged to and sliding upon the rod y, and Vsupported by the hook-bracez, as and for the purpose set forth.

6. In combination with an endless delivery apparatus and a receptacle, C, to. receive the cut grain, the binders foot-board W, hinged to the main frame, and supported by the jointed braces p, and the tables Y Y, sliding upon the hinge-rod y and supported by the hook-bracez, all in the manner set forth.
