IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 33,557, dated October 22, 1561; reissue No. 5,714, dated December 30, 1873; application filed July 13, 1872.

To all whom it may concern:

Be it known that I, JAMns PINE, of Troy, in the county of Rensselaer and State of New York, have invented anew and useful Improvement in Grain and Grass Harvesters, of which the following is a specication:

Figure 1 is a side sectional view of my invention, taken on the line a' w, Fig. 2; Fig. 2, a front view. Fig. 3 is a top or plan view.

Similar letters of reference indicate corresponding parts in the figures.

The invention consists in the. main franie of a harvester, constructed in one piece, and projecting in front and rear of a revolving axle, which has its bearings in holes in the frame. The invention consists also in loosely journaling the drive-wheels which actuate the cutter-bar mechanism upon a prolongation of the fixed cross-bar of inain frame, so that no separate shaft will be required, and so that the harvester may be thereby greatlyT simplified. It also consists in the Inode of arranging the main frame, the gear-frame, and fin# ger-bar with the axle, as hereinafter fully de scribed.

To enable those skilled in the art to fully understand and construct 1ny invention, I will proceed to describe it.

A represents an axle, on the ends of which wheels B. B are placed, and C is the main frame of the machine, through which the aXlc A passes. D is the draft-pole, which is attached to the front end of the main frame G by a horizontal bolt or pivot, a, said bolt or pivot passing' through a socket, b, on which the draft-pole is fitted, the socket being rlnly secured to the main frame. On the axle A there is iitted loosely a band, c, to which a bar, d, is connected, said bar being perforated and iitted in a slot in the back end ofthe draft-pole D. Through the back end of the draft-pole a pin, e, passes horizontally, said pin passing through either of the perforations of the bar d. By adjusting the pin e higher or lower in the bar d, the main frame G may be more or less inclined, and the iinger-bar and the front or cutting edge of the sickle, hereinl after referred to, brought nearer to or farther from the surface of the ground, asymay be desired. At the back part. of the main frame C there is placed a shaft, E, on which the back part of a gearfranie, F, is fitted loosely, and allowed to swing freely. On the shaft E there is fitted loosely a wheel, G, which wheel has a pinion, H, attached concentrically to it, said pinion gearing or meshing into teeth at the inner side of wheel B. The gear-frame F may be of V form, its forked or branched back end being fitted on the shaft E, and its front end having the iin ger-bar H attached to it by a joint, f. On the nger-bar a sickle is placed and driven from the wheel G by any proper ineans. The iinger-bar H is braced by a rod, I, from shaft E. To the right-hand side of main frame C there is attached a lever, J, which lever has a pulley, K, secured to it. To the lever J there is also attached a ratchetsegment, L, with which a This pawl M is provided with a foot-piece, g, which projects from it at the point where its fulcruin-pin h passes through it. On the .pin h there is placed a half-pulley, N, over the periphery', of which a chain or cord, i, is passed, said chain or cord passing down and being attached to the finger-bar H. The chain or cord i also passes around the pulley K, and is brought forward and attached tothe front piece g of the pawl M. By this arrangement of the half-pulley N, pulley K, and chain or cord i, the linger-bar and sickle may be very readily elevated, not much power-being re quired to effect the result. The pawl M, by engaging with the ratchet-segment L, retains the finger-bar at the desired height, and the pawl may be disengaged from the ratchet-seginent at any time by depressing the foot-piece g. By attaching the gearfra1ne F to the main frame C, as described, and having the wheel G placed loosely on shaft E, and not connected directly with the gear-frame, the latter will not have any downward pressure exerted upon it, as would be the case were the wheel G connected with it. This is an important feature of the invention, for much friction is avoided by the pressing down of the finger-bar on the surface of the ground. By having the draftpole D attached, as shown, so that its back end may be adjusted higher or lower, the sickle may be made to cut higher or lower, as desired, and by having the iingerfbar H attached to the front end of the gear-frame by a joint, f, and the back end of the gear-fran1e tf pawl, M, engages.

ted loosely on shaft E, the linger-bar is allowed to conform perfectly to the inequalities of the surface of the ground, While the rod I serves as an ecient brace for the ringer-bar.

Havingthus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The main frame C of a harvester, having the front and sides constructed in one piece,

and projecting in front and rear of the main axle, which has its bearings in holes in the frame, substantially as specified.

2. The arrangement of attached Wheel and pinion G H loosely upon a prolongation ofthe fixed cross-bar E of the Inaiu frame C, as and for the purpose set forth.

3. The gearframe F, pivoted to fixed cross bar E 0f main frame C, having finger-bar pivoted thereto, combined With a brace, I, extending` from said cross-bar E, as described.

JAMES PINE.
