SPECIFICATION forming part of LettersPatent No. 784,664, dated March 14, 1905.

' Application filed December 19,1902. Serial No. 135,839.

To all whom it may concern:

Be it known that I, SAMUEL K. DENNIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

My invention is concerned with automatic grain-binders; and it consists of certain novel mechanisms by which I facilitate the passage of the grain from the elevator canvases onto the binder-deck and to the packers.

To illustrate my invention, I annex hereto two sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which Figure 1 is a rear elevation of portions of the grain-binder having my invention embodied therein. Fig. 2 is a detail illustrating some of the parts in a'difierent position from that shown in Fig. 1. Fig. 3 is a longitudinal section, on a somewhat-larger scale, illustrating a construction and operation of the adjustable conveyers. Fig. 4 is a detail view of one of the conveyers detached and with one side thereof removed. Fig. 5 is a top plan View of the conveyers, and Fig. 6 is a perspective view of a chain-link having a carrying-spur formed thereon which I employ in connection with the conveyers.

The first part of my invention is concerned with a novel fork or rake 10, which I employ in connection with the triangular connectingframe 11, by which the platform-canvas and the lower elevator -canvas are driven and which forms the subject-matter of my application Serial No. 70,058, filed July 29, 1901. This rake 10 consists of a plate or casting secured to the upper angle of the frame 11 and having a plurality of teeth which during the movement of the frame 11, which is hung on the cranks 12, 13, and 14, describes a circle, a portion of which is in the path of the ends of the grain passing through the upper portion of the elevator and over onto the binderdeck, the invention being employed in connection with what are known as open-ended elevators used .for binding long grain and in which the heads project out from between the end boards 15 and 16 of the elevator and into the path of the teeth of the rake 10, which serves to carry the ends of the grain over the gap between the top of the lower elevatorcanvas 17 and the binder-deck 18.

The second part of my invention is concerned with a novel conveyer, of which I preferably employ two, which serves to carry the grain positively from the elevator-canvases down the binder-deck to where it is el'igaged bythe packer-arms. Each of these mechan isms, as best seen in Figs. 3 to 5, consists of 27, sprocket-chain 28, and sprocket-wheel 29.

from the shaft 30 of the upper roller of the top elevator-canvas. The action of the teeth 20 as the machine is run is to cooperate with the grain as soon as it is discharged from the elevator and carry it down upon the binderdeck to the packer-arms. The conveyers can be slid along the shaft 26 to any position of adjustment that may be desired for the different lengths and positions of grain and retained wherever desired by means of the detent 31, pivotally mounted on the handle 32, extending from and secured to the side of the con- Veyer. The detent 31 is provided with the handle 33, which, by means of the helicallycoiled expanding spring 34, interposed between the handles and 32, is held in engagement with the chosen one of a series of notches 35, formed in the strip 36, preferably composed of angle-iron and extending across the top of the elevator in position to hold the conveyors in any desired position of adjustment. As the plates 23 can swing freely upon the hubs of the sprocket-wheels 21, it will be apparent that the conveyers have a floating action by which their position and the pressure on the grain being acted upon will vary with the amount of grain passing through the machine, as the lower ends thereof will be held by gravity in contact with the grain passing beneath them. To prevent the conveyers being thrust upward so that the lower ends thereof would contact with the plate 37 when they are beneath it, I form the stop 38 on the end of the latch 31 in position to prevent such a possibility.

ith the one or more conveyers adjustable transversely of the elevator it will be apparent that I can locate them in any position that may be best adapted to deal with the particular kind of grain being cut, whether it be long or short, straight or tangled, &c.

While I have shown my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of n'iodifications and that I do not desire to be limited in the interpretation of the following claims, except as may be necessitated by the state of the prior art.

W hat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a harvester, the combination with the open-ended elevator, of the binder-deck adjacent thereto to receive the grain from the elevator, the triangular frame for rotating the canvas-rollers of the elevator at the open end thereof, and the comb secured to the uppermost angle of said triangular frame in position as it moves to engage the projecting ends of the grain and carry it from the elevator to the deck.

2. In a harvester, the combination with the elevator, of the binder-deck adjacent thereto adapted to receive the grain from said elevator, and an endless conveyer transversely adustable at its point of support located at the top of the elevator and extending downward over the deck in position to engage the body of the grain and carry it to the packer-arms.

3. In a harvester, the combination with the elevator, of the binder-deck adjacent thereto adapted to receive the grain from said elevator, and an endless conveyer transversely adustable at its point of support located at the top of the elevator and extending downward over the deck in position to engage the body of the grain and carry it to the packer-arms, said conveyer consisting of a toothed sprocketchainfcooperating with a pair of suitably-supported sprocket-wheels.
