UNITED- STATES PATENT .OFFICEo A. PALMER AND S. Gr. WILLIAMS, v0F BROGKPRT, NEW YORK.

Specification forming part of Letters Patent No. 8,192, dated July 1, 1851.

To all whom it 'may concern.'

Be it known that we, AARON PALMER and S. Gr. WILLIAMS, of Brockport, in the county of Monroe and State of New York, have invented a new and Improved Harvesting-Machine; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification- Figure 1 being a perspective view of the en; tire machine, and Fig. 2 a perspective view of aportion thereof detached.

Similar letters indicate like partsin both the figures.

The frameof our harvesting-machine is composed of the side pieces, F G, the end pieces, I J, and the transverse piece H. The main wheel A of the machine is placed between the end I and the transverse piece H of the frame, and has its bearings in the arch-support E,

Vrising from the transverse piece H, and in a corresponding support rising from the end I ofthe machine.

D is the platform for the reception of the heads and upper portions of the stalks of the grain as they are severed by the cutting apparatus M, which is located at the fron-t edge of the said platform. A straightfence or guard, O, rises from the inner edge'of the platform D, and a curved guard, N, rises from the outerV edge of the same. An inclined rail, d, issupported above the guard N, as represented in Fig. 1. At the rear end ot the rail d a short rail or gate, f, is jointed thereto, the rear end of which rests upon the guard N, and beyond the extremity of the hinged rail f a rail, g, surmounts the after edge of the guard N, which has an upward inclination. rIhe rake U is connected to the operating-lever B by arms which are hinged to the said lever. The lever B has toothed legs a b projecting from its inner end, which embrace the ears e e, that project outward from the wheel-bearing support E. A

i'ulcrum-pin, s, passes down through the legs' n b of the lever `B and through the ears e e, which supports the lever in a horizontal position, and on whichit can turn freely.

Within a recess in the face of the wheel A ject, as shown in Fig. 2, which series of teeth c,which projects from its outer extremity, passes from beneath the hinged portion j' of the inclined rail d, and when the lever B is turned forward the rake C is elevated from the plat? form D as it is pushed forward by the action of the pin c in passing up and bearing upon the inclined raild. The leverBis turned rearward by the action of the series of p teeth p upon the teeth in the extremity ofthe levers leg n, and it remains in its extreme rearward position during about two-thirds the revolution of the wheel,when the series of teeth g strike into the teeth in the levers leg b and carry the lever forward so far that the pin c, projecting from the rake O,will pass over the angle of the rail d and allow the said rake to fall upon the front edge of the platform D. The instant that the series of teeth q cease their action upon the teeth of the levers leg b the series ot' teeth p take into the teeth in the leverslega and turn the lever and the rake rearward again.

It will be perceived that the grain is discharged in such a position as to be entirely out of the way ofthe horses which draw the machine during their succeeding tour around the eld.

The arrangement of the operating-lever B is such as to enable the gearing which operates it to be located within a recess in the'wheel A, and thereby prevents the access ot' dirt to it, which would interfere with its free action, and would cause the speedy destruction ofthe operating teeth. The series of teeth ,fp q may be located within a recess in the wheel A; or a protecting rim or liange may surround them.

The apparatus M for cutting the grain may be constructed and operated in any well-known or usual manner.

What we claim as our invention, and desire to secure by Letters Patent, is

The discharging the cut stalks and heads of grain from the platform D by means of the vesting-machine signed and witnessed this .combination ofthe rake C with theleverB, and 25th day ot' February, 1851.

'the (zo-operation therewith ofthe series of teeth p q 0n the face of the Whee1A,and the inclined o AovlgljsR' rail el, rising above the curved guard ot' the platform D, substantially in the manner here Witnesses:

in set forth. G. B. WHITESIDE,

The above specification of'our improved har- GEORGE W`. SOLES.
