- M/MA' UNITED STATES To all whom it may concern:

Be it known that ADAM R. REEsE, of Phillipsburg, in the county of Warren and State of New Jersey, did invent certain new and useful Improvements in Automatic Rakes for Harvesters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents aview, inperspective, of a harvesting-machine, to which my improvements are applied; Fig. 2, aview, in elevation, of a portion of the same, as seen from behind, with the rake-arms detached; and Fig. 3, a plan or top view of some of the parts shown in Fig. 2.

In the accompanying drawings, a stout main or gearing frame, A, is shown as supported upon two large driving-wheels, B. The linger-beam C andplatform D are hinged to the frame by means of the drag-bar E and coupling-link F, or in any other usual and wellknown way. A stop chain, c, serves to pre'- vcnt the finger-beam from descending too low. The raking mechanism is mounted in 'a bracket, H, supported by an arm, I, the lower end of which is bolted to the finger-beam in such manner that it may readily be detached when desired.

The rake-arms .I are pivoted near one end to a ring, j, mounted upon a spindle, K, turning in bearings in the bracket H, and the proper rising and falling movements are communicated by means of a stationary guide-slot or cam-ring, L, in which the ends of the rakearms traverse, being provided with frictionrollers to make them run more easily. A rake, J1, is mounted upon one only of the arms, the others being provided with blank-heads J2, which act as reel-r'bs to press the grain back upon the platform, but not to rake it off. The rake-shaft is rotated by means of an endless chain, M, encircling a pulley, N, on the driving-axle O and a corresponding pulley, P, on the rake-shaft. The rake is prevented from descending too low by a stop, S, uponthe frame. The operation of the machine is such that, as it advances through the field, the rake-arms are caused to enter the standing grain and PATENT GEEIGE.

IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 41,641, dated February 16, 1864; Reissue No. 2,464, dated January 22, 1867.

press it back against the cutting apparatus, which severs it. The continued backward movement of the arms then deposits the grain upon the platform, whence it is swept by the rake, and dischargedin gavels upon the ground. rlhe rake and heads, after passing over the back of the platform, are elevated until they occupy a position nearly at right angles to their former one, as shown in Fig. 1, in which attitude they move forward over the gearing-frame until the proper moment for them to descend to enter the standing grain, which movements are repeated at every revolution of the rakeshaft.

It is obvious that the ,rake-shaft could be used in an inclined as well as in an upright positionby a corresponding alteration of the guide-slot, the mode of driving the rake affording great facility of adaptation to such changes.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a floating-beam harvester, a rake-standard rigidly attached to and vibrating with the platform, and supporting the rake-shaft between tlie driving-wheels.

2. The combination of radial rake-arms, pivoted between the vertical rake-shaft and the rake-head, and a guide located between the rake-shaft and the pivot.

3. The combination of revolving rake and reel arms with a camway between two parallel cams, for the purpose of keeping the rake and reel arms firmly in position while revolving.

4. The combination of a hinged platform, a support of the revolving rake rigidlyattached to and moving withthe said platform or lingerbeam, and radial pivoted rake-arms.

5: The combination of the rake-shaft K with the driving-shaft 0 by means of the endless chain lVI, when arranged and operating substantially inthe manner described, for the purpose of driving the rake in any position of its shaft without the intervention of gearing, as set forth.
