NIMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 142,490, dated September 2, 1873; application filed January 21, 1871.

To all whom it may concern:

Be it known that I, JAIRUs B. MOMILLLN, of North Vernon, in the county of Jennings and in'the State of Indiana, haveinvented a new and useful Improvement in Rakes for Harvesting-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, in which- Figure 1 is a perspective view. Fig. 2 is a plan; and Fig. 3 is a sectional view, showing the rake-post, rake-arm, trip-lever, and the front and rear rake-trips.

The construction of my rake is such that it may be worked by the drivers feet as a footrake, or by the machine as a self-rake; and it is easily changed from one to the other.

To operate as a foot-rake, the machine is provided with a foot-lever, A, which has a cross-foot, R, where it is pivoted to the machine, convenient for the drivers feet to rest on as he sits on his seat. The cross-foot extends to the right and left far enough to afford leverage for the driver to vibrate the le-,

ver A easily with his feet. The lever A extends back, under the drivers seat, to the rear of the machine. To the grain -platform, just at the rear of the reel post, is fixed a roundpin upright. This pin fits in the hole in the rake post 0 at M, and holds the post perpendicular as it turns on the pin. To the rake-post O, at the side next the machine, is fixed an iron, D, with holes through each end. In the front end of this iron D one end of the connecting-rod B is hooked, and the other end is connected to the rear end of the foot'lever A. This connects the foot-lever A and the rake-post 0.

As the driver presses with his right foot the right-hand end of the foot of the lever A, he causes the rear end to vibrate to one side of the machine, thus imparting motion to the connecting-rod B and the rake-post O, which turns on the pin at M. When he relaxes the right and presses with his left foot, the motion is reversed.

Near the top of the rakepost O, to the side opposite the iron 1), is pivoted, at N, the rakearm E, and to the lower end, at O, is pivoted one end of the trip-lever F. Its upper end is provided with a roller, P, which stands out far enough to run in a slot in the lower end of the rake-arm E, thus connecting the rake-arm E and the trip-lever F. Near the front of the platform, at the foot of the reel-post, the front trip G is bolted; and the rear trip His bolted to the platform at the rear of the rake-post G. The rake I is bolted to the upper end of the rake-arm E in such a position that it describes nearly the fourth of a circle across or over the platform.

As the rake-post 0 turns on its pin at M the rake must turn with it. As therake approaches the front of the platform in its elevated position the trip lever F comes in contact with the front rake-trip G, which raises the upper end of the trip-lever F, and causes its roller 1? to pass to the top of the slot in therake arm E. This draws the lower end of the arm E to the post 0, and slightly lowers the rake I. As the post 0 turns farther on its pin it causes the roller P topass down in the slot, and the lower end of the arm E to pass to the opposite side of the rake post C. When the roller 1 reaches the lower end of the slot in the arm E it looks the arm in that position. At the same time the rake I is thrown down on the platform, and locked there until, as the rake is making its sweep across the platform to rake off the gavel, it reaches the edge of the platform at the rear of the machine. The trip-lever F strikes the rear rake-trip H, which causes the roller P to pass, first, to the top, then to the lower end of the slot in the arm E. The lower end of arm E is passed to the opposite side of the post 0, and the rake is raised to its elevated position, and held there until the triplever F comes in contact with the front trip Gr, when the rake has again made its forward sweep over the platform. As the rake is raising and delivering its gavel at the edge of the platform, its head is gradually turned and easily freed from the grain. This decreases the tendency to string out and scatter the gavel.

To change from a foot to a self rake it is only necessary to disconnect the rod B from the front end of the iron D, and connect it with the rear end and to the crank-wheel J at the end of the axle tree. As this wheel J re volvcs with the axle tree, motion is given to the rod B, post (J,and rake I, which makesits circular sweep across the platform the same as when operated as a foot rake. The wheel J has slots in its outside, which the pin thatpasses through the end of the aXle tree fits in, and causes the wheel to revolve with the axle-tree. But to enable the driver to rake at will, the inside of the wheel J has ahub,which is grooved, and supports the forked end of the rod K, the other end of which is pivotedto the machine at Q. The rod L is connected to the rod K just back of the drive-wheel, and with the rear end of the footlever A when used as a self-rake.

By this arrangement the driver can, with his feet, disconnect and connect the pin at the end of the axle-tree and the slots in the wheel J, as the wheel fits loosely, and is easily moved to and from the pin at the end of the axle-tree, making the wheel revolve or stop at pleasure, to make the gavels uniform in size in heavy or light grain. By this arrangement I have a combination-rake that can be operated either as a foot-rake or self-rake; and it is easily changed from one to the other by simply changing one rod. It is simple in construction-consequently cheap and durable, and easily understood by the farmersnot liable to get out of order, but easily repaired, if out of order, by an ordinary mechanic, because ofits simplicity; and it is a side delivery.

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

The combination and arrangement of the rake-post O, the rake-arm E, the trip-leverF, the front trip G, and the rear trip H, and the footlever A, the connecting -rod B, and iron D, when used as a foot or self rake.
