IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 15,882, dated October 14,1856; Reissue No. 3.055, dated July 28, 1868.

To all whom it may concern:

Be it known that CARLOS W. Gloves, of Roxbury, in the county of Litchfield and State of Connecticut, invented a new and Improved Grain and Grass-Harvester, on which Letters Patent of the United States were granted, hearing date the 14th day of October, 1856; that the said Letters Patent; have been assigned to me, JOHN G. PERRY, of Kingston, in the county of Washington and State oflthode Island; and that the following is a full, clear, and exact description of such invention, reference being bad to the accompanying drawings, making a portion of this specification, in which- I Figure 1 is a side view of aharvester constructed according to this invention. Fig. 2 is a vertical section of the same in the plane indicated by the line m w in Fig. 1.

Similar letters of reference indicate corresponding parts in both figures.

This invention consists in so constructing and operating a vibrating sickle-driving mechanism of a harvesting-machine that such mechanism shall work through the drivingwheel of such machine, whereby when the sickle-bar is situated nearly or quitein thesame vertical plane as the axle of the machine the power may be more directly and consequently be more efliciently communicated to the sickle than when such mechanism is arranged to work outside the periphery of the supportingwheel.

The invention further consists in certain novel means whereby the principal feature, just mentioned, of theinvention may be very effectually carried out and the sickle-bar be adjusted for cutting at different heights.

To enable others to understand the construction and operation of the invention, I will proceed to describe it with reference to the drawings.

A represents the driving-wheel of the machine, which is formed with a broad tread, at, having formed centrally upon its inner side a flange, b, which on its outer surface, at a short distance from its edge, is furnished with cogs 0.

B shows what may be termed a guidebox, consisting of a grooved segment fitted over or upon the edge of the flange b, and designed to extend around about three-fifths of the internal circumference of the flange. The groove in this segment should be of V shape, as shown at d in Fig. 2, the internal edge of the flange I), just mentioned, being of corresponding shape, so that the guide-box may not have unnecessary play or be liable to work loose in consequence of wear.

0 is avertioalshaft, which works in bea rings 6 on the outer side of the guide-box I). lower end of this shall; has upon it a pinion,f, gearing into the cogs c on the flange b. The shaft 0 has furthermore a toothed wheel, 9, placed loosely upon it, and is enabled to turn with the shaft in one direction by means of a clutch, h, attached to such shaft, the wheel 9 remaining stationary when the shaft is turned in the opposite direction, as by the backing of the machine, so that the sickle may not be operated thereby during such backward movement of the machine.

1) is a shaft working in hearings on the inner side of the guide-box B, and furnished with a pinion, h, which gears into the toothed wheel g, thelatter passing through'the central space oropening of the driving-wheel,asshown more fully in Fig. 2, and at the upper end of the just-mentioned -shaft D is a hand-wheel, i.

The linger-bar is represented at E, and has its inner end attached to the lower portion of the guide-boxB, such innerend havinga curve, j, in it, so that it may be somewhat higher than the outer orremaiuing partot' the bar, as shown in Fig. 2.

F is a bar connected by joints K with the higher portion j of the linger-bar E, and near the driving-wheel. This bar F is attached to the finger-bar at right angles thereto, and has attached toits back end the drivers seat- G, while the draIt-pole ot' the machine is attached to its forward end.

H is a rod attached at one end to the outer end of the bar F, and having its opposite end passing through a handle, I, attached to the guide-box B. This rod H may be fixed to the handle at any desired point by pins passing therethrongh, or by any other suitable means, so that by turning the guide-box B, through the agency of the handle I, the cutting-edges of the sickle, attached to the fin ger-bar, may be The ing-wheel, by means of its cogs e, rotates the pinion fof the shaft 0, and through the agency of the wheel 9 and pinion It causes the shaft D to revolve to operate the sickle connected in the usual or in any suitable manner therewith. The mechanism working through the driving-wheel, as hereinbefore explained, the power designed to drive the sickle is transmitted thereto through the interior of the driving-wheel, and is thus enabled to act more directly and consequently more efficiently than would be the case if such power were conveyed by'niechanism arranged to work past or externally to the circumference of such drivingwheel. Furthermore, the sickle being driven by the shaft D, and the driving device being within the driving-wheel, it is kept-free from cut grass or grain.

The cutting-edges ofthe sickle may be raised orlowered by the driver, when on his seat, while the machine is being drawn forward; and in case the sickle should become clogged, the

driver, by turning the hand-wheel z, may free the same. It should further be mentioned that the guide-boxB should have allowed to it some slight vertical play on the flange b, so that the sickle may rise and fall to conform to inequalities in the surface of the ground over whichit passses.

WVhat I claim as the invention of CARLOS W. GLoVER, and desire to secure by Letters Patent, is- 7 1. So constructing and operating the vibratingsickle-driving mechanism of a harvesting machine that such mechanism shall work through the driving-wheel of the machine.

2. The combination of the cogs e on the driving-wheel, the pinion f, upright shaft 0," and wheel 9 with the pinion h of the shaft D, arranged substantially as and for the purpose specified.

3. The combination, with the driving-wheel, of the guide-box B, bar F, rod H, and lever I, in such manner that the angle of presentation of the cutters carried by the finger-bar E may be adjusted substantially as set forth.

JOHN G. PERRY.
