INLPROVEMENT IN HARVESTERS.

The Schedule referred to in these Lettere Patent and making part of the same.

To all whom 'it lrnd/y concern.-

Be it known that I, HENRY HOWE, of Oneonta, in the county of Otsego, and State of New York, have invented a new and improved Mowing and Reaping- Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being. had to the accompanying drawings, forming part of this specification.

Figure l represents a side elevation of my improved mowing and reaping-machine.-

Figure 2 is a horizontal section of the same, 'taken on the plane of the line :c x, iig. 1.

Similar letters of reference indicate corresponding parts. o

This invention' relates to certain improvements on the mowing and reaping-machine for which I made application for Letters Patent on or about the 15th day of J uly,l868, the objeetof which was-to equalize the draught, or rather to lregulate the action of the draught, on the machine, and to allow thel machine to cut while turning.

The present invention has the same object, and refers to those machines in which lthe motion is transferred' from the wheels to a counter-shaft, while the aforesaid application had reference to those machines in which the driving-wheel shaft received and transmitted the motion.

The present invention consists in hanging on each end of the counter-shaft a loose pinion, each pinion being connected with the counter-shaft, by means of a ratchet-spring clutch.

The pinion on the left-hand side is smaller than the other, and it will, as it meshes into internal gear of the left-hand driving-wheel, carry the counter-shaft around, while the other pinion will remain idle, not being able to revolve with the counter-shaft. The strain of the-Whole machine is thus thrown upon the left-hand side, and consequently taken away from the cutting-side, the machine being thus properly balanced. l

When the machine is turned around the left wheel, the right-hand pinion will carry4 the counter-shaft.

A, in the drawing, represents a 'suitable frame of the machine.

B is the mainl axle.

O is the driving-wheel on the left-hand side.

D, that on the right-hand side.

E is the counter-shaft, hung in the frame A, or a desired.

Each wheel C D has internal gearing, as shown, that on the wheel D being larger in diameter than that on O.

Upon the ends of the counter-shaft are hung, 'respectively, the pinions a andb, a meshing into O, and

b into D, as shown.

The pinion a. is necessarily smaller in diameter than h, as it meshes into the smaller internal gear of O, its

axis being as far from that of G as that of the wheel bis om the axis oif the larger internal gear of D.

The pinions a b turn quite loose on the respective ends of the shaft, and each pinion meshes, with ratchetteeth on its inner edge, into a' sliding clutch, of which one, e, is arranged near e, and one, d, near b, on the shaft E.

These clutches are, by means of springs, held against their respective pinions, so that, when, by either of the pinions, the clutch is turned in the direction of the arrow in lig, 1, the counter-shaft will also be turned, and will convey its motion, by means of suitable mechanism, to the cutter-bar and other machinery of the harvester. Instead of the clutches c d, other equivalent devices maybe used.

When the machine is drawn straight ahead, both wheels C D revolve, with equal velocities, and still independent of each other, on the fixed axle B.

Each-wheel C D turns, also, its pinions a b; vButit is evident that, owing to the smaller diameter of a, it should turn quicker than its larger opponent, b consequcntly the counter-shaft will be revolved by the action of C' on a., and b will slip loose on it, and on its clutch d. The strain on the cutter-bar is thus balanced by throwing all working power upon the leftvhand wheel G.

The internal gearing of the wheels lC D need not be as diierent as described; the axle E may be oblique, to bring the pinions c b against the toothed edge, the difference in size of aand b being important.

The wheel O is described as being on the left-hand side of the machine. This refers only tothose machines that have their cutting-apparatus on the righthand side, the wheel C, with the small pinion a, being on the side opposite to the cutter-bar.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is The pinions a b, hungloosely on the ends of the counter-sha E, and connected respectively with sliding spring-clutches c fl, or their equivalents, and meshing into the internal gearing of the driving-wheels O and D, respectively, the pinion a, on the opposite side of the cutting-apparatus, being smaller than b, substantially as described, for the purpose of balancing the strain of the machine, and for allowing it to cut when it turns a corner, as specified.
