IMPROVEMENT IN H'ARVESTINiG-MACHINES.

Specification forming part of Letters Patent No. 33,158, dated August 27, 1861.

.To @ZZ wiwi/wit may concern:

Be it known that I, JAMESM. ORPUT, of Malta, in the county of DeKalb and State of Illinois, have invented certain new and useful.

Improvements in Harvesting-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention consists ot' a swinging frame that carries the sicklcs at any height that may be desired by the driver of the machine and delivers the grain into the box of a wagon to which it is attached.

To enable others skilled in the art to make and use my machine, I will proceed to describe its construction and operation. Figure l of the drawings is an end elevation, and Fig. 2 is a side elevation, of my said machine. Fig. 8 is a detached plan view of the parts by which the sickles are operated, as will be hereinafter more particularly described.

The axle-tree a t of the wagon B is prolonged at one side to carry the frame of the harvester. At the outer end of the axle is tenoned the post c, which is braced by the horizontal beam d to the vertical post e. which is built on the side of the box ofthe wagon. The stay-rodf gsupports the outer end ofthe axle by bracing it to the opposite side of the wagon. The horizontal frame 7L of the harvester swings on the axle a and carries the sicklest t', the gathering-wheel 7c, the elevating endless apron Z, and the apron m, and the machinery by which they are operated. The lever oz, by which the height of the sickles from the ground is graduated, is pivoted in the middle of itslength to the post e, the forward end being furnished with a handle alongside of the drivers seat, and the hind end with a rod, o, connected to the rear end of the swing- It is also fitted with several pinholes at the centers of motion, by which it may be adjusted. The serratedplates or sickles v3 z' have reciprocating motions simultaneously in opposite directions, which are derived from the spur-wheel 19, placed on one of the Wagonwheels. The wheelp gears into a pinion, q, on thetransverse shaft r, which also carries a cam, s, grooved for the reception of the ends of the levers t t, which are supported by the suspension-rods y y, and cross each other like a pair of shears at the :Fulcrum u. The grooves. of

the cam s start from nearly the same point on the surface, thence diverge and come together in an elliptical manner, and again. diverge and come together at the point ot' starting. A single revolution of the shaft r thus occasions four transverse motions of each sickle, and the movement of each is always opposite t0 that of the other, so that when one moves to the right the other moves to the left, and vice versa, thus shearing the grain that may be included between their several points. The pinion q is held in position by the clutch o, which is operated by the lever w, that passes to the top ot' the machine, where it may be reached by the assistant in the box ofthe wagon. The gathering wheel lc is driven by a crossed belt from the pulley x on the shaft i', which also carries the pulleys by which the endless aprons are driven. The lever w thus controls the movements of all the working parts of the harvester. The frameot1 the machine and the gearing and aprons may be arranged in any suitable inanner; but I prefer the. arrangement shown in the drawings.

Y The operation of the machine is as follows: As the wagon progresses over the ground, the rotation of the hinder wheel rotates the shaft rand operates the sickles,thegathering-wheel, and the aprons, the gatheringwheel presses the grain down against the sickles, by which it is cut oft", and the elevating-apron carries it up to a height sufficient to clear the wheel and transfers it to the apron m, by which it is delivered into the box of the Wagon. The driver may at any time depress or elevate the sickles by the lever n, as is indicated by the red lines of the drawings, to accommodate them to the variations in the height ot' the grain; and the operation of the working parts ofthe machine may be stopped by the assistant who trims the grain in the box by simply uncoupling the pinion q by the lever w.

I claim as my invention and desire to secure by Letters Patent- The arrangement of the vibrating frame carrying the cutting apparatus, reel, endless aprons, and gearing upon the axle a, and adjusting the same by means of the lever n, substantially in the manner described, and for the purpose speciiied.
