IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters FatentuNo. 170,086, dated November 16, 1875 application filed May 17, 1875.

view of the-table with the rake attached.

Fig. 2 is a vertical section of the raking me- Fig. 3 is a plan of the stationary plateas seen from below when looking up, and

i Fig. 4 is a plan view of the revolving cam-plate.

The same letters are employed in all the figures in the designation of identical parts.

A is the table or platform on which the grain is held until a gavel has been collected. A hole is cut through the rear end of the platform, and a plate, B, is adjustably attached thereto by bolts passing through a series of slots near the edge of the plate. This plate may be cast iu one piece with the sleeve- B1, around which is placed the oscillating pipe C, turning freely on the sleeve. It has an arm, G1, through which an oscillating movement is communicated to it `through the following-described mechanism:

A bell-crank lever, D, is pivoted at its angle to the plate B, and supports at one end the friction-roller-Dl, and at the other the link E, the outer end of which is bolted to the arm G1, the bolt passing through the segmental slot B2 in the plate B. The frictionroller-D1 is fitted into the irregular groove FV, in the cam-plate F. The form of this groove is substantially as shown in the drawing,

Fig. 4:. The cam-wheel revolves continuously when in gear, deriving motion from any convenient part of the machinery, and the movement of the parts D and E, dependent thereon, communicates an irregular oscillation to the pipe G; At the upper end of the pipe is al sprocket, O2. Within the sleeve B1 is the shaft G1 keyed to the cam F, and revolving continuonslywith it and carrying the arm G,

which is bolted to a bracket on top of the rhe bracket is provided with slots to regulate the tension of the chain. On the outer end of the arm Gis a round rod, G2,

wheel F and oscillating pipeG,actingthrough 4 the sprocket-Wheels C2 and H2, and the end- A less chain I..

The form of the cam F1 is such that, as the arm G revolves, the rake being in theposition shown in Fig. l, the chain I will draw back the rake-head so that it will traverse the front side of the platform immediately Vbehind the cutters, and so sweep the cut grain from a. to b'. I When the rake reaches b it will stand nearly parallel to the side of the platform, and so it will be drawn from b to c, when the grain is dropped on the stubble, when the free end of the rake is drawn rapidly toward the arm G, passing under it as it is in line with the draft projecting directly to the rear, and then rapidly thrown forward until the teeth pass over the platform at d, from which point to a the fork is projected, the arm H being nearly parallel to the side.

I have 'illustrated the fork as passing under the arm G. It is, however, obvious that the machine can readily be modified, so that the fork may pass over the arm, and otherY form may be modified.

, 2. In combination with the oscillating pipe G, the arm G, continuously revolving on its own axis, the sprocket-wheels C2 H2, chain I, and rake H, having also an independent rotation, substantially as set forth,

3. The adjustable slotted plate B and sleeve B1, in combination with the oseille-ting pipe C and the continuously-rotating shaft G1, for oommunioating a constant rotary movement to the rake-arm, and an irregular indepenb ent ,movement to the rake, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

. PLINY F. HODGES.
