IMPROVEMENT IN HARVESTERS.

Specilication in'nling part of Letters Patent No. 120,407, dated October 3l, 1871.

'To all whom `it may concern.:

Be it known that l, JOHN I). Winnen, ot' Poughkeepsie, in the county oi' Dutchess and State ot' New York, have invented certain novel Improvements in llarvesting-lllachincs5 and I do hereby declare that the following is a i'ull, clear, and exact description thereot', retercnm. bein had to the accompanying drawing makingl part ol' this spec4 iiication, in whichlligure l, llate l, is a plan view ot' the improved machine, without the cutting :,ipparatus and driverls seat. Fig. 2, Plate l, is an elevation of the right-hand side of the machine. Fig. .'5, Plate 2, is an elevation ot' the Rathaud side ot' the machine. Fig. ,4, Vllate L', is an inside view ot' the lett-hand shoe, showing its curved arm attached to it by a rocking eye and screw. Fig. 5, Plate 2, is a lwrspective View ot' a slotted supporting-and-lit'ting plate.

Similar lettersot' reference indicate corresponding parts in the several figures.

This invention relates to certain novel improvements on the reapingai1d-1nowing machine for which Letters Patent ot' the United States were granted to me bearing date respectively on the 10th day oi' FebruaryJSli, and on the 5th day oi' April, 1870, wherein the cutting apparatus is applied on the ends, diverging arms extending out in front ot' a two-wheel drat'tt'rame.

The tbllowing description will enable others skilled in the art to understand my invention.

ln the accompanying drawing, A A represent two transporting wheels, which are applied on an axle, l5. U represents a broad platform for sustaining the drivers, which is connected loosely to the axle B by means oi' eye-bearings a a, and which forni..` a. rear expansion ot' the draft-pole. All this has been fully explained in the schedules annexed to my Letters latent above ret'er ed to. 1') represents the rectangular frame o1' thc inachine, which is arranged bclowthe axle and connected to it by journal-boxes, so that it can oscillate freely. VBeyond the front ends of this trame extend two arms, E Ef, which are curved outward, and have connected to their front ends two shoes, fj', which shoes are connected together by means of a iinger-beam, 1*", as shown in the drawing. The rear end ot' curved arm E is pivoted directly to the axle B, between the frame l) and hub oi" wheel A, and the frontend ot' this arm is received into a recess made into the rear end ot' shoe f, and connected to this shoe by a transverse pivot, m., which. will allow the shoe with the iinger-bar to rock freely. The rear pivoted minnection ofthe arm E allows its t'ront end to be raised or depressed at pleasure, as will be now explained. A downwardly-tlaring recess or slot, r, (see Fig. 2,) is made into the outer righthand side ot' framel), near its front end, and into the outer right-hand side ot' frame E, near its i'ront end; and into this slot l is applied loosely a slotted stirrup, s, which is kept in place by the arm E, lying close alongside ot' the frame 1), and also by means of a suspension-chain, 7i', which is attached. to the upper end of said stirrnp, and also i'o a grooved segulent-pulley, J, on a rockshat't, li. The segment J is fast on shaft h, which latter is supported by standards rising from the platform U, and carries on its inner end next the driver a hand-lever, by which the driver can rock the segment and raise or depress the stirrups s, at pleasure. 'lhc slot o, which is through the stirrup s, receives into it a pill, p, proieeting from the arm lil, which pin serves in a measure as a guide for the stirrup in its slot in frame D. The lower end of the stirrup is split centrally, and the ends s s turned in opposite directions, as shown in Fig. f. The end .s extends beneath the frame l) and the end s2 extends beneath the arm E, so that while the shoe j' is allowed to rise and fall freely and independently oti the fran'ie l), still, whenever desired, this shoe, together with the entire cutting apparatus, and also the front end oi' the frame l), can be raised by drawing back the arm on shaft li. lt it is desired to have the arm E and frame D rigidly connected, this can be done by simply inserting a bolt through holes .1', made for its reception. The arm E', on the lett-hand side of the machine, is rigidly conneeted to the frame l), or it may forni part ot' the frame. This arm E is loosely connected to a shoe,

j', the attachment being eii'eeted as follows: g

represents an eyebolt, the eye portion of which is inserted loosely into a recess made transversely into the rear portion ofthe shoef, and coniined therein by means of a. pin, c. The end ot' arm E is rounded and applied into a recess made into the inner side ot' the shoef, as shown in Fig. 4. 'lhe recess for the eyebolt and that for the end oiV` arm Ef are slightly larger than the parts which are applied in them, so that these parts are allowed free rocking motions. The screw portion of the eyebolt g passes through the end of' arni E and receives a nut, t', on it. Ii' desirable, two eyebolt attachments may be employed. To the rear end of the couplingpin e a right-angular lever is attached, which is pivoted to arm E', and arranged in a convenient place to the attendant on his.seat. By means of the lever c and the rocking motions allowed the shoes and fingerbar, the attendant can give any desired degree of pitch to the cutters, according to the condition ofthe grass to be cut. Should it be desired, at any time, to pitch the cutting apparatus either downward or upward and rigidly hold it in one or the other of these positions, this can be done by inserting a bolt into a hole, al, through the arm E', so that this bolt will either be below or above the pin e. The guides or directors b, for pressing the grass in toward the center of the machine, are spring metal rods, the front ends ot' which are inserted into holes made into the elevated portions ot' the shoesj'j", and the rear ends of which are inserted into holes made into the caps to the journal boxes of axle B. These rods b are of such length that they require to be arched to be inserted or spring into their places, which arch form they afterward retain, as shown in the drawinfl'. The rods b are held in their places by their own spring action tend' ing to straighten them.

1t will be seen from the above description that the finger-bar is allowed, when desired, to rise and fall bodily, or to rise and descend at each end, so as to accommodate itself freely to the undulations of the surface passed over. Also, that the undulatory movement can be prevented whenever it is desired to have a rigid finger-bar. Also, that the attendant has complete control over the cutting apparatus so far as giving the required pitch to it; at the same time, provision is made for locking the linger-bar when pitched either downward or upward.

What 1 claim as my invention, and as an im provement in front-eut harvesters, and which l desire to secure by Letters Patent, is

l. The combination of arm E jointed to shoe j', and shoe j" Ijointed to arm E', substantially as described.

2. The stirrnps s, suspended by a chain, k, from a raising and lowering device, in combination with the Ljointed arm E and frame D, sub stantially as described.
