i IMPROVEMENT IN HARVEKSTING-MACHINES.

Specification forming part of Letters Patent No. 15,659, dated September 2, 1856; Reissue No. 673, dated March 15, 1859; Reissue No. 3.199, dated November 17, 1868.

To all whom t may concern:

Bc it known that I, WILLIAM A. KIRBY, formerly residing in Buffalo, in the State of New York, now of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Harvesting-lVIachines and I do hereby declare the following to be a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents in perspective so much ofaharvesting-machine as will illustrate my invention. Fig. 2 represents a perspective view taken from the opposite side of the machine from that shown in Fig. 1, and illustrates the manner of supporting the seat and driver on the main wheel.. Fig. 3 represents in perspective a portion ofthe frame and gearingdetached from the machine to better illustrate their characteristics.

Similar letters of reference, where they occur in the separate gures, denote like parts of the machine in all of the drawings.

This invention relates to a harvesting-machinein which the main franieis wholly on one side ofthe driving-wheel, and in which said drivin g-wheel has no outside support, butlwhich has a foot-support for the driver on the side of the wheel opposite to the main frame; and the invention further relates to a harvestingmachine with the frame wholly on one side of the driving-wheel, and the driving-wheel having no outside support, and the frame in two parts, one ofwhich supports the driving-wheel and a portion of the gearing, and the other part carrying the otherportion ofthe gearing, vand a projection formed on one part of the frame around thc pinion-shaft and a corresponding opening inthe other part, which will pass over and around said projection, thus forming ajoint the center of which is coincident with the center of the pinion-shaft, for the purpose of holding the two parts with their gearing in position longitudinally; and the invention further relates in a harvesting-machine having its frame in two parts, one of which supports the driving-Wheel and aportion ofthe gearing, and the other part carries thev other portion ofthe gearing, the use ofa lug on one part of the frame and a corresponding recess on the other part thereof, inwhich said lug works, for the purpose of holding the two parts, with their gearing, in positionlaterally.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

The main frame of the machine, calling that the main frame which carries the gearing or moving or'drivingparts oi'the machine, is composed of two parts-viz., the triangular part A B C and the part H, hinged thereto-each of these parts carrying a portion of the driving-gear, as follows: The triangular part carries the shaftG and the pinion b, while the other part, H, carries the main wheel K, or forms a support for it, and said wheel has upon it the cogged rim J, which takes into the pinion b, giving it and its shaft G motion, which inotion is transmitted to the cutter-bar to drive it, and through the hinged joint or connection between the two frames or portions offrames.

The tongue D is connected to the triangular` portieri ofthe frame rigidly at its front portion and the finger-bar E at its rear portion.

On the piece A ot the frame there is a rnetallic box, block, or bearing, F, through which the shaft G passes, and in which it is supported. A hub, t, 'projects from this block F, on which is placed the other portion of the frame H, which has an opening through it, that will slip over the projection t' and turn upon it and freely move thereon as the two parts of the frame work upon each other. There is also a flange, a, on the piece H, which projects into a slot or recess, n, in the block, box, or bearing F, to steady said piece H on its journal or bearing when turning thereon, and which prevents it from slipping laterally on said bearing to any injurious extent, or keeping them in propergearing position. lheobject and purpose of hanging the piece or part H upon the hub or projection t' are that it may turn on a bearing of which the shaft Gr is a center and without turning on the shaft itself, which would from its rapid motion soon so wear tself or the hub or bearing of the piece H, or both, as to produce a shackling, noisy, and irregular motlon; and, besides, it takesthe strain and friction from the shaft and transfers it to the frame; and the object and purpose of the tiange or guide a. working in the recess n or against lateral supports are to keep the pieceH upon its bearing and prevent it from moving laterally.

Apnlley,b,is fastened on the shaft G, which may hear against a circular flange, J, on the inner face ot' the main drivingwheel K, so as to receive motion therefrom; or b may be a cogged pinion and the flange J a cogged rim or flange taking into it to drive it; or an cndless belt or chain may be used around the two, the object being to get motion from the main drive-wheel and transmit it through the gearing to the cutters, or to a reel or rake, as may be desired. y

L is a segmental rim supported on the piece c ofthe frame, and is furnished with a groove or way, c, in its inner perimeter, in which groove or wayc the outer edge ot' the piece H moves and is supported. Aprojectingpiece,d,is also formed on the inner perimeter of the rini L, against which an adjusting-pin placed in one of the series of holes e e, Ste., may take or catch to hold the frame at a proper adjustnient or position on the main Wheel K.

' On the part or piece H is wrought or casta journal, lVI, for supporting the main wheel, or for supporting the frame in the main wheel, and to said piece H there is also pivoted by a bolt or pin, N., a brace or support,0, provided with a series ot' adjusting-holes,ff, &c.

Asupport or brace, P, corresponding to that of O on the opposite side ofthe Wheel, is pivoted to an arm, Q, connected with or fastened to the journal or axle M ofthe main Wheel K, and at the outer extreme end of saidjournal or axle, as seen in Fig. 2, and similarly provided with adjusting-holes ff, 85e. To these two braces or supports O P is hung or supported a seat, R, (for the driver or conductor of the machine to ride upon,) which, besides having a pivoted connection with the supports, is also hinged and made adjustable in the standard S by a pin,g, which may pass through its end and through said standard at any of the adjustingholes h, 85e. The lower end of the brace or support P may be formed into a stirrup, T, to in akea foot-support for the driver,

the axle M being the principal supporting part of said stirrup, inasmuch as the support Pis connected to or with the outer end of said axle,

y and thus forms the place for the stirrup.

By pivoting the part or piece H, as above stated, to the other part of the main frame, and hanging the wheel K to said part H, and also pivoting the seat R (which is also a lever) to the piece or part H and the standard S, which latter is a part of or fastened to the main frame, the trame can be raised or lowered and balanced on the wheel at pleasure; but in raising or lowering the main frame the position of the seat It changes, for it may be used as a lever hy which the raising and lowering may be done, and some provision must be made for bringing it back into an effective or convenient position again. rThis is done by the adjustments heretofore mentioned in the braces O P and standard S. By these connections, too, I not only make the adjustments that are necessary for high or low cutting with great facility, but l dispense-with much of the framework heretofore used, and consequently make the machine lighter and cheaper than heretofore done, dispensing with all kinds of frame on the out or stubble side of the main wheel and placing said frame entirely on the in or grain side of said wheel.

The peculiar position and manner of hanging the seat makes the weight of the driver or conductor on its rear portion act as a counterpoise or balance to raise and hold up the front part of the machine, or aid in so doing.

Thepin used in the holes c ot the piece or part His inserted underneath the projection d ot" the rim or guide L, so that when the machine is cutting close to the ground, or the frame is on or close to the ground, and the drivingwheel K should drop into a depression of any kind, it will still be in contact with the ground and continue to drive the cutters, which it could not do were it permanently adjusted to the main frame-and said frame come in contact with the ground.

Any snddenjar communicated to a harvesting-machine with a sti' tongue is brought violently upon t-he necks of the horses that draw it; but by my manner of hanging the seat the weight ot' the driver, when the machine strikes any obstacle, tends to raise up the machine, ease the jar, and thus relieve the horses.

It will be perceived that I have no main frame outside of the main wheel, but simply a seat-l support and foot-rest, which are connected to the extreme outer end of the journal or axle of the main 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 entire main frame is on the cutter-bar side of the main wheel, and there is but one `support to the journal or axle of the main wheel, and that on the side where the main frame is placed.

Having thus fully described4 my invention, what I claim under this patent, and desire to secure by Letters Patent, is

1. In a harvesting-machine with its frame wholly on one side ot' the driving-wheel and the drivin g-wheel having no outside support, a foot-support for the driver on the side of the wheel opposite the frame, substantially as described.

2. In a harvesting machine with a frame wholly on one side ot the driving-wheel and said driving-wheelhaving no outside support, the making of the traine in two parts, one of which supports the driving-wheel and a portion of the gearing, and the other part carries the other portion of the gearing, and forming a projection on one part of the frame around the piniongshaft, and a corresponding opening in the other, part, which will pass over and around said projection, thus forming a joint the center ofwhich is coincident with the' center of' the pinion-shaft, for the purpose of holding their gearing in position longitudinally,

substantially as described.

3. In a harvesting-machine having its frame in two parts, one of vwhich supports the driv ing-wheel and a portion of the gearing, and

' the other part carries the other part or. portion -of the gearing, and jointed together by the projection on one and the opening in the other,

as described, the use ofthe lng, flange, or guide Vafon one part of -the frame and a-eorrespondf in g recess, n, on the other part thereof, in which said lng, ilange, or guide works, for the par, pose of holding the two parts, with their gem', ing, in position' laterally, so as to prevent nio: tion to either side,"substantially as described,
