IM PROVEM ENT IN HARVESTERS.

Specification forming part of Letters Patent No. 11,951, dated November 14, 1865; Reissue No. 970, dated June 5, 1860; Reissue No. 1,3!5, dated June 3, 1862.

To all whom it may concern:

Be it known that I, JACOB SWARTZ, of the city of Buffalo, i'n the county of Erieand State of New York, have invented new and useful Improvements in Grain and Grass Harvesty ers, of which the following is a full, clear, and

exact-description of the parte thereof' requisite for a proper understanding of such of said improvements as are herein` claimed, reference being had to the accompanying drawings, forming part of' this specilication, in which Figure l represents in perspective a sidecutting harvester embracing my imprgvements, certain parts only ot' which are herein claimed. Fig. 2 represents in black a front view of the entire machine, (many parts of which are shown only for illustrating the connection and variation of the parts claimed,) with the bottom ofthe shoe and divider on the same horizontal line or resting on thecommon surface ot' the ground and the main ground and driving wheel perpendicular, or nearly so, and a vertical plane from the ground passing through the center of the hinge-pin, which connects the shoe to the vibrating end of the coupling-arm, for showing the longitudinal variation ot' said shoe from the main frame when raised or lowered in respect thereto. Fig. 2 also shows'in red the finger-bar raised above the ground for reaping,while the main ground and driving wheel remains in the same vertical position. Fig. 3 represents a top view ot' the coupling-arm and hinge-pins which con# neet it to the hangers and the shoe to the arm;

and Fig. 4 represents a side view of the shoe, with the cavities therein for the branches of the coupling-arm, and in and between it and the finger-bar a guideway for the heel of the cutter-bar and a slot for the cutters.

The tnger-bar ot' the cuttingapparatus which I use is ofthe short laterally-projecting class, whose outer end has' no connection with the main fram'e of thev machine, and the inner end or heel of which does not extend across the plane in which the main ground` and driving wheel moves, and the cutters of which recipngers "in straight lines; and the improvement claimed under this patent consists in so connecting said cutting apparatus to the main frame'of the machine that the longitudinal distance between its inner end or heel and said main DIVISION U.

frame will be varied when raised or lowered in respect thereto. The shoe, lingers, and divider have at the front edge of' the linger-bar slats, through which a scalloped cutter reciprocates in a straight line. rllhat end of the finger-bar which is connectedto the shoe and terminates` at or near its inner edge I call the inner end l or t hee1,7 and that en'dto which the divider is connected and Which runs next to the uncut crop I call the outer end. y

Of the parts herein specified, A represents the main frame ot' the machine, by which the other parts are supported (except they main ground-wheel and its axle, on which the frame and other parts are supported) and drawn forward; B, the tongue, by which `it i`s drawn forward; U and D, two hangers extending somedistance below the frame, in the lower end of each of' which there is a hole, in linev with each other and with or nearly with the `path of the machine; E, the coupling' arm, through the lbranches of each end of which there is a horizontal hole for the hinge-pins,

which hold it and the finger-bar, which fol lows all Athe ordinary undulations of the sur".

face ofthe ground, about at right angles to the path of the machine; a, the front branch of the end ofthe coupling-arm, which is connected with hangers C and 1'); b, the rear branch of the same end; c, the front branch ot'its vibrating end,and d the rear branch of the same end; F, the shoe at the inner end or heel of the tinger-bar; c and f, cavities in said shoe for receiving the branches c and d; g, the

guideway in and between the shoe andtingerbar for the heel ot' the 'cutter-bar andY a slot for the cutters; h, the hinge-pin,which couples branch e to hanger C; i, that which couples branch b to hanger D; j, that which couples thefront end of shoe F to branch c, and 7c that which couples its rear end to branch d; G, the linger-bar; Z l l Z Z, its lingers, and m the divider a-t its outer end; n, the cutter-bar; o o o o o 0, its cutters secured thereto, and p the pitman, through which they receive their reciprocatory motion; H,themain ground and driving Wheel, which carries the main frame and gives motion to the cutters; I, its axle fastin it; q and r, the boxes in which the axle revolves; s, the drop-clutch, by which the main vdriving-odg wheel is held in and out of gear with its pinion J on its shaft K, which revolves in its boxes t and u; -L and M, two posts exten ing above the frame. there is hinged one end of a toggle-lever, N, to the other end of which is hinged one end of toggle-lever O, whose other endis hinged'to the upper end of avibratinglever, P, which is pivoted at fu to post M, and has its lower end hinged lo pitmanp at the proper place, as shown by the drawings, for keeping the cutters and tingers in the same or nearly the same relative position to each other when raised or lowered in respect to the main frame of the machine. The proper place for that end of the pitman which .receives its motion from the drivin g-wheel, and also the length of the pitman, will always be determined by the distance between its connection with the. cutter-bar and the connection of the coupling-arm with the shoe; and when the pitman and coupling-arm can be of the same length they should have the same cornrnon center at each end. 0n the end of shaft K is placed a crank, fw, iu which ijs placed a wrist-pin, on which is placed the lower end of a connecting-rod, y, through the upper end of which passes the hinge-pin which' connects the toggle-levers N and 0 together.

It will be seen that by the arrangement of ,f parts just described the cutters will receive two motions each way during every revolution ot shaft K.

Q represents the post, which extends up from shoe F to arm R; a', the hinge-pin,which connects its upper end to arm R, whose other end is hinged to post M by hinge-pins b; c', theverticalguide-sl'ot in postL,throu gh which the set-screw d" passes into arm It, which parts limit the extent of the vibration ot' the inner end of the 'cutting apparatus toward and from the main frame ot' the machine to the length of slot c.

It will also be seen that the cutting apparatus can be raised from the ground, and that the construction and connection of parts which enable this to be done when the tongue is rigidly connected to the main frame ofthe machine, as mine is, also enable the shoe of said cutting apparatus to pass into a depression of the surface while the lower periphery of the main groundand .driving wheel is passing over an elevation of the surface, by the set-screw not being in the lowest part of its slot when 'said divider-shoe and lower periphery of the wheel are on the same horizontal plane. And it will also further be seen that by raising the cutting apparatus to the desired height, and then tightening the setscrews in its slot', said cutting apparatus can be retained at various (heights above the ground.

In order to properly balance the machine and prevent side draft therein, it may be neeessary to place the tongue between the wheel and shoe.Y To do this the main frames width and the coupling-arms length require to beincreased so much that the animal between the tongue and standing crop will not walk on theV crop.

main frame.

I do not wish to be understood as claiming d. To the upper end of L l the invention of that class vot' harvesters the outer end ofthe finger-bar of whose cutting apparatus has no connection with the main frame of the machine and the inner end or heel of A which does not extend across the plane in which the main ground and' driving wheel moves, and the cutters of which reciprocate across the tinger's in straight lines, as I am aware that previous to my invention such,y an apparatus existed, but either with the finger-bar thereof rigidly connected tothe main frame ot' the machine, or so connected therewith that tlielongitudinal distance between its inner end or heel and main frame was not varied when raised or lowered in respect thereto; but I am not aware that previous to my invention a cut-v ting apparatus, the outer end ot' whoseingerbar had no connection with the main frame of the machine and the inner end or head of which did not extend across the plane in which the main ground. and driving wheel moves, and the cutters. of which reciprocated across ,the fingers in straight lines, was also so connected to the main frame of the machine that the longitudinal distance between the inner end of the finger-bar and main frame would be varied when raised or lowered in respect there` to. Therefore I do not wish to be understood as limiting myself` to the particular method of constructing and connecting the several parts shown and described, as it is obvious that various modifications may be made therein without departing from the principles and spirit contained in my invention and,therefore,

What I do claim under this patent is l. The combination, with the main frame of a harvester, of the coupling-arm E, linger-barY G, and cutter-bar n, substantially in the manner described.

2. The combination, with the main frame of a harvester, of the coupling-arm E, finger-bar G, cutter-bar a, and pitman p, or their equivalents, snhstantially in the manner described, whereby the relative position of the cutters and tingers to each other is not materially varied when raised or lowered in respect to said 3. Limitingthe ofthe above-described cutting apparatus will vibrate from and toward the main frame, to

which itis connected by the uprightpost Q, arm

can be retained at various heights above the ground, substantially as described.
