Application filed January 28, 1919. Serial No. 273,607.

To all whom it may concern:

Be it known that I, WILLIAM R. REED, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in GrainConveyers, of which the following is a specification.

This invention relates to grain conveying devices of harvesting machines or self binders, whereby the grain is conveyed from the platform to the binder table. Ord' arily, these devices consist of upper a (1 lower endless conveyer belts or aprons between which the grain is carried. The present invention has for its object to provide a conveyer structure in which the upper apron or canvas is eliminated, whereby the structure is simplified, and also to provide a novel and improved means for directing the grain onto the lower canvas and assuring the proper forward feed of the grain.

The objects stated are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings forming a part of this specification.

In the drawings,

Figure 1 is a front elevation of the conveyer mechanism; Fig. 2 is an elevation of said mechanism viewed from the front of the machine; Fig. 3 is a longitudinal section of the mechanism, and Fig. 4 is an elevation of the mechanism viewed from the rear of the machine.

Referring specifically to the drawings, 5 denotes a fragment of the platform of a grain binder across which works the usual slatted conveyer apron 6, the latter carrying the grain to an elevator canvas 7 which delivers the grain to the binder table 8. Ordinarily, an upper elevator canvas is used in connection with the lower canvas 7, but this upper canvas has been eliminated, and in its place there is provided a cover plate 9 which is hinged, as shown at 10, to the frame of the elevator, and is held suspended above the canvas 7 by a chain or other suitable suspension device 11 attached to the seat bar 12 of the machine. The hinged end of the plate 9 is the upper end of the same, and the chain 11 is connected to the lower end of the plate. The plate 9 is thus left i Specification of Letters Patent.

9 has an upward curve,

free to yield upwardly to prevent grain from clogging between the same and the canvas 7.

As shown in Fig. 3, the plate 9 is held in spaced and parallel relation to the canvas 7, and it extends from the upper end to within a short distance of the lower end of said canvas. The lower end of the plate as shown at 13, so that the grain entrance end of the space between the canvas 7 and the plate 9 is flared. vThe plate 9 is also located inside the front guardboard 14: of the elevator.

Above the lower or receiving end of the canvas 7, and beneath the flared end 13 of the plate 9, is a rotatable grain beater, the same comprising a drum 15 armed with radially extending fingers 16. This drum has

trunnions

17 and 18, respectively at its ends. The trunnion 17 is supported by a bearing bracket 19 carried by the seat bar 12, and the trunnion 18 is supported by the board 14.

On the trunnion 18 is a pinion 20 which is in mesh with a pinion 21 obtaining motion from the driving means of the canvas 7 Any other suitable driving means may be provided. The drawings show the pinion 21 on a shaft 22 having a sprocket wheel 23 which is driven by the drive chain 24 of the canvas 7. v

Between the adjacent ends of the canvas 7 and the binder table 8 is the usual butt adjuster 25, which, in this instance, is made longer than usual to extend close to the up per end of the canvas 7.

In operation, the grain is delivered by the platform canvas 6 to the lower end of the canvas 7, and the latter carries the grain to the binder table 8 as usual. The grain, in passing to the receiving end of the canvas 7, comes beneath the beater roller 15 and the fingers 16 of the latter assure the proper passage of the grain to the canvas and also loosen up the grain and spread it. The grain, as it is carried upwardly by the canvas 7, is held down on the latter by the plate 9, and as this plate is free to yield upwardly, clogging of grain is effectually prevented.

The device hereinbefore described is very simple in constructions and devoid of complicated par-ts liable to get out of order, and it can be applied to existing machines Without alterations in the general structure means adjustably and. yieldingly holding thereof.
