JACOB GRAYBILL, OF AKRON, OHIO.
IMPROVEMENT IN HARVESTER-RAKES.
Specification forming part of Letters Patent No. 150,237, dated April 28, 1874; application filed February 14, 1874. v
. To all whom it may concern.-
Be it known that I, Jaoon GRAYBILL, of Akron, in the county of Summit and State of Ohio, have invented a new and useful Improvement in Automatic Bake for Harvesters, of which the following is a specification:
Figure l is a top view of my improved rake, shown as applied to a harvester-platform. Fig. 2 is a rear view of the same, the platform being shown in section. Fig. 3 is an edge view of a modified form of the rake-arm. Fig. 4 is a side view of the same.
Similar letters of reference indicate corresponding parts.
The invention will first be fully described, and then pointed out in the claim.
A represents the platform, and B the rear part of the frame, of a harvester. To the frame B are securely bolted two or more arms, 0, to the rear ends of which is secured a vertical plate, 1), the ends of which are made circular, and the middle parts of its upper and lower edges are concaved, as shown in Fig. 2. Upon the upper inner edge and the lower outer edge of the plate D are formed rearwardlyprojecting flanges d (1 Upon the lower inner part and the upper outer part of the rear side of the plate 1), and at a little distance from its edge, are formed curved flanges d d, which are so arranged that their ends may be opposite to or slightly overlap the ends of the flanges d (1 as shown in Fig.2. E is a shaft, which revolves in bearings attached to the frame B, and which is designed to be driven by bevel-gear wheels from the aXle of the drive-wheels of the machine. The shaft E passes through a bearing in the center of the plate D, and to its projecting rear end is attached a short cylindrical head, F, which is slotted or mortised transversely to receive the arm G. The arm G is slotted longitudinally to receive the end of the shaft E, which thus acts as a stop, to limit the longitudinal movement of the said arm G. The arm G is car-* ried around by and with the cylinder F in its revolution. To the inner side of the arm Gr, at a little distance from the inner end of its slot, is attached a pin, 9, which should be provided with a frictionroller, and which, as the arm G is carried around by the cylinder F, moves along the track formed by the flanges d d d at, and thus causes the arm G to slide longitudinally back and forth through the cylinder F. To the end of the sliding arm G is pivoted the end of the rake-arm H, which is bent twice at right angles, or made with an equivalent curve near its pivoted end, so that it may pass the end of the cylinder F. The rake-arm H passes through the vertical slot of a guide-bar, I, which is connected with and supported from the frame-work of the machine by an arm, J. In the lower end of the slot in the guide-bar I is pivoted a small roller, K, to diminish the friction as the said rake-arm moves back and forth. To the forward end of the rake-arm H is attached the rake-head L, by which the grain is drawn from the platform A and dropped to the ground.
By this construction, the rake-head is drawn A across the platform A, sweeping the grain before it, and upon its return movement is carried above the said platform, so as not to disturb the grain, the roller K .of the slotted guide I acting as a fulcrum to support it.
Upon the lower edge of the forward part of the rake-arm H is formed a rounded projection, h, which, by coming in contact with the roller K, raises it from the platform A as soon as it leaves the inner edge of. said platform, and sooner than it would be raised if said projection were not used. M is an inclined plate, attached to the outer end of the platform A, to prevent the out grain from falling so close to said end that the teeth of the rake L cannot drop beyond it. The inclined plate M is slotted, so that the teeth of the rake-head L can pass through, and thus always pass beyond the grain lying upon the platform.
hen the device is to be attached to a forward-cut machine, the rake-arm H should have a hinge or joint formed in it at or near its angle or bend, and its forward part should be curved, as shown in Figs. 3 and 4.
N is the cut-off, to keep the cut grain from falling upon the platform A while the rake is sweeping the grain from it. To the inner end of the cut-ofi N is attached, or upon it is formed,
an arm, 0, projecting at right angles, and
which, near its end, is pivoted to the reel-post P. To the end of the arm or lever O is pivoted the upper end of the connecting-rod Q, the lower end of which is pivoted to a short crank, R, formed upon or attached to the outer part of the shaft S, which works in bearings attached to the reel-post P and the frame of the machine. Upon the inner part of the shaft S is formed, or to it is attached, a short crank, T, to which is pivoted the end of a connectingrod, U, the other end of which is pivoted to the lower end of the lever V, which is pivoted to the frame of the machine, and its upper end projects into such a position that it can be conveniently reached and operated by the driver to lower and raise the cutoff, as required.
Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- The flanged plate D d d d d, the shaft E, the mortised head F, slotted sliding arm G, provided with a guide-pin, g, elbow rake-arm H, and the slotted guide-bar I in combination with each other, and with the frame-work and platform of a harvester, substantially as herein shown and described.
