IMPROVEMENT IN HARVESTING-MACHINES.

Specification forming part of Letters Patent No. 15,659, dated September 2, 1856; Reissue No. 673. dated March 15, 1859.

To ali whom, it 'may concern:

Beit known that I, \'VILLIAM A. KrnBY, ot' Butfalo, in the county ot' Erie and State ot'New York,haveinvented certain newaud useful Improvements in Harvesting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the construct-ion and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in Which- Fignre'l represents a perspective view of so muchof a harvesting-machine as will illustrate the character of my invention. Fig. 2 represents a perspective view taken from the opposite side ot' the machine from that shown in Fig. 1, and shows` the manner of supporting the seat and driver on the main wheel.

Similar leters of reference, where they occur in the separate figures, denote like parts ofthe machinein both the figures.

The nature of my invention relates to the manner of hanging or uniting the frame of a harvesting-machine to the main supportingwheel so that the former may be raised or lowered and balanced on the latter to suit the special character ot' the ground over which it is to be worked or the work to be done by it; and my invention further relates to the inauner of attaching a lever-seat to the'uiain frame and wheel so that the weight of the driver may be used in raising or balancing the machine and transferring the weight upon the main or drive wheel.

To enable others skilled in the art to make and use my invention, I will proceed to describe the saine With ret'eren ce to the drawings.

The frame is of a triangular shape, (A B G forming the three sides of the triangle,) to.

which frame all the remaining portions ot' the machine may be connected. connected to this frame rigidly at its front, and the linger-bar E at its rear.

In a suitable metallic box or block, F, on the part A of the trame is substantially xed a journal or shaft, G, so as to freely turn in said box. A hub also projects from this block F, on which is placed a segmental or radial plate, H, said plate having a hub, I, upon it, which gives ita proper support on the projection of the box F. There is also a iiange or guidepiece, (non the segmental plate H, which projects into a slot or recess in the block F to The tongue D is.

| steady said segmental plate on its journal or bearing when turning thereon.

b is a pulley fast on the shaft G, which may bear against a circular flange, J, on the inner face of the main driving and supporting Wheel K, so as to receive motion therefrom; or b may be a cogged pinion and the tlauge J a cogged flange taking into it, or an endless belt may be used around the two, the object being to get motion from the main wheel and transmit it to the cutters through the shaft G or to a reel 0r rake, as may be desired.

L is a segmental rim, supported on the framepiece O, and furnished with a groove or way, c, in its inner perimeter, into which groove or way the outer edge ot' the plate H moves and is supported. A projecting piece, d, is also formed on the inner perimeter ot' the rim L,

against which an adjusting-pin placed in either ot' the series ot' holes ce, Ste., may catch to hold the frame when properly adj Listed on the main wheel K.

On the segmental plate H is wrought or cast in a journal, M, for supporting the main wheel K, and to said plate is also pivoted by a bolt or pin, N, a brace or support, O, provided with a series ot' adjnsting-holes,ff, Src. A support `or brace, P, corresponding to that (O) on the opposite side of the wl1eel,'is pivoted tov an arm, Q, connected with or fastened to the journal or axle M ofthe main wheel K, as seen in Fig. 2, and similarly provided with adjusting-holes f, 85e. To these two braces or supports O P is hung a seat, R, (for the driver or conductor which, besides having a pivoted connection with the supports, is also hinged and made adjust-able in the standard S by a pin, g, which may pass through its end and through said standard at any ot' the adjustments h, Snc. The lower end ot' the brace or support P may be formed into a stirrup, T, to make a footsupport for the driver, the axle M being-the main supporting part of said stirrup, inasmuch as the support P is connected to or with the aXle,'and thus forms the place for the stirrnp. By thus pivoting the plate H to the frame, and hanging the wheel K to said plate, and also pivoting the seat lt (which is also a lever) to the plate H and the standard S, the frame can be raised or lowered and balanced onthe wheel at pleasure; but in raising or lowering the frame the position of the seat R changes, for it may be the lever by which the raising or lowering is done, and some provision must be made for bringing it backl into a convenient or et'- fective position. This is done by the adjustments heretofore mentioned in the braces OP' and standard S. By these connections, too, I not only make the adjustments that are necessary for high or low cutting with great facility, butJ I dispense with much of the frame- Work heretofore usetL'and consequently make the machine lighter and cheaper than heretofore done. The peculiar position and manner of hanging the seat make the weight ot' the driver or conductor 011 its rear portion act as a counterp'cse or balance to raise and hold up the front part of the machine. The pin is to bevinserted in one ot' the holes e underneath the projection d, so that when the machine is cutting low or the frame is on or close to the ground and the driving-Wheel K should drop into a depression ot' any kind it will still be in Contact with the ground a nd continue to drive the cutter-bar, which it could not do were it permanently adjusted to the traine and the frame come in contact with the ground. Any

sudden jar communicated to a machine with a stift' tongueis thrown violently upon the horses necks; but by my mannerot' hanging the seat Vthe Weight ot' the driver, when the machine strikes any obstacle, tends to raise up and ease thejar, and thus relieve the horses. l

It will be perceived that I have no frame outside of the main wheel, but simply a seatsupport and a foot-rest, which are connected to the journal or axle 'of the wheel, and which aid the driver in converting his seat into a lever for raising up'or easing the machine over any obstruction in its path. The triangular frame, to which all the other parts of the machine are connected, is on the cutter-bar sideot' the main wheel. There is but one support to the journal or axle ofthe main Wheel, and that on the side where the main frame is placed.

Having thus fully described the nature and object ot' my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

l. The combination ofthe single plate H and main wheel, substantially as described.

2. The combination ot' the main wheel K, single plate H, and rim L, when connected t0- gether land. operating in the manner and for the purpose set forth.

3. Placing a vibrating wheel 0n the outside ot' the traine, or so -that the outside ot' the frame does not bear on the outside of the wheel, in combination with the triangular-shaped frame onthe inside ofthe wheel, substantially as described.

4. Hanging the seat to the plate H and to the standard S, in the manner and for the purpose set forth. y

5. A hinged lever-seat and outside stirrup or supporter, in combinationwith a wheel having` no outside trame or support, substantially as herein represented. A
