HQHarnnwav, of Rock Stream, in the county of Yates, and State of New York, have invented a new and useful Improvement in Harvesters; and Ida hereby declare that the fol lowing is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in whichi Figure 1 is a perspective view.

I These improvements relate to the class oi'harvesting machines set forth in Letters Patent granted to G. M4 Hathaway andinyself, on the 28th day of May, A. D. 1867, and consists irncertuin improvements in the construction of the same, as will be fully set forth in the following specificatiouand claims. a l k The machine is intended for use either in reaping or mowing. In eithercasc the driving-mechanism remains unchanged. The machine is supportedupon two wheels, A A. These wheels are neither of the same size, nor

on the same transverse line. The wheel A is the driving-whcel,. the revolution of which actuates the cuttingmechanism; it runs upon the axle B, whichis bent at right angles at B", and extending downwards, supports in part the cutting-apparatus, in a manner to be hereinafterdescribed. The tongue C is rigidly attached to the axle B. A brace extending fromthe tongue, at its junction with the axle, supports the driver's seat D, which is so placed that the weight of the driver shall assist in counterb'alancing the mechanism placed in the front axle. The driving-mechanism giving motion to the cutter is enclosed within a hemispherical case, E, surround ing and attached to the axle. The open end of the hemisphere is covered by a'revolving plate, F, turning around the axle. This plate is caused 'to revolve by the wheel A, which-is connected, with it, by means of a pawl or pawls, G, shown in fig. 7. The stem is inserted in a hole drilled into the hub of the wheel, and when the wheel is revolving forward, the point of the pawl catching into notches in the rim of a recess, G, in the hub of the plate-wheel F, into which it is pressed by a spring' placed behind it, will cause the plate-wheel]? to revolve with the driving-wheel; but when the driving-wheel is revolving backwards, the pawl slipping over the inclined sides of the notches, does not actuate the plate-wheel. It is sometimes desirable to stop the cutters when the wheel is moving forward. This I accomplish in the following mannen A collar, G, is placed on the end of the hub, with a flange extending over the end of the hub, and notched to receive the point of the pawl at the same time with the notches in the recess G. When the machine is in action, the hub and the collar'will revolve together.- There are two notches in the inclined surface, on which the pawl rests against the collar,"the one already "referred to, and another nearer the centre of revolution, so placed that when thepoint of the pawl rests in it, it will not come in'contact with the notch in the hub. It will therefore depend on which of the two notches in the collar the pawl is held in, 'whether the plate-wheel will revolve with the driving-wheel or not. In order to give this control to the collar, it is surrounded by a yoke, G, attached to the lever; G. One end of the yoke is carried around the collar, and attached to a rod, G, having lugs, which pass through slots in the lever G, and permit a play to the rod, suflicient to tighten or loosen the yoke on the collsrysc that the collar may I T 14,085 a 2 either revolve around the hub or be so confined that the hub shall revolve with the collar. I'have shown, in

.-fig.j 8, another arrangement for attainingthis end, when the lever G is extended down so that its point may be set in holes in the collar, or be raised above them. By shifting the lever when the collar is connected with it, by either of these or any similar devices, from the lower to the upper notch in the edge of the case E, the pawl may be drawn back out of the notch in the hub, and .held in the inner notch in the collar, when the wheel will revolve without actuating the plate whcel. Three planet spur-wheels, H, are attached to bosses, projecting from the inner face of the plate-wheel F. These wheels are driven by cogs E, on the inner edge of the cuseEyand drive the central pinion 1, which is cast on the back of the bevel-wheel I, which turns on the axle within the case. The bevel whecl drives the bevel-pinion K, on a shaft, K, which, passing through the case, carries the crank, K*. The pitman L is attached to the crank, and extending down to the finger-bar M, drives the knives M within the guards M, all constructed in the ordinarymanner. The finger-bar is attachedto a shoe, N, which is supported in front by the wheel N, and suspended from the brace N, bolted to the case E, and fastened to the tongue C. This brace is attached to the shoe by a wrist, which, projecting from the brace, passes through a lag on thc top of the shoe. The rear end of the shoe is in like manner attached to'a wrist on the lower extremity of the bent endB of the axle. The cutter-bar, turning upon these wrists, may be folded up by any of the devices in use .for that purpose. 0 is a bar, fastened by a round bolt passing through the brace N and attached. to the .bent end B of the axle, by a yoke, O, passing around the latter. On the end of this bar is a wrist, which forms the axle for the wheel A. This wheel may be arranged to run on'either the outside or inside, by causing the wrist to project outwardly or inwardly. To raise 'or lower the cutter-bar, a lever, P, has its fulcrum on the axle B, the short end of the lever being connected by a rod, P, with the bar on By thgowing the long end-ofthe lever forward or back, thecutter-bar may he raised or lowered. Arod, 1, extending back from the brace'N through a yoke on the lever near the axle, should be constructed with notches on its edge, to receive a pawl on the lever, by which the cutting-apparatus may'bc held at any required height between the extremes. Q isthe platform, which is adj-ustahly connected with the machine,'by means of the points Q, which rest upon the finger-bar, having pins projecting down into the bar, and by the stump ,R, which, hanging from the spindle of. the wheel A, is hook-ed at R into the edge of the platform. The outer shoe S is a casting, attached to the end of the finger-bar, and a wrought-ironpoint, S, bolted to the end thereof, on top, and extending forward, terminating in a sharp point The lower part extends back to the rear of the shoe, where it is bent upward, and having a series ofholes through it, is adjustably fastened by a pin, so that the outer end of the finger-bar may be raised or lowered.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The planet-wheel5 H, when attached to the inner face of a,revolving plate, F, so adjustably connected with the driving-wheel, that it may be caused to revolve on the axle, or remain stationary, substantially as set forth v 2. The mode of throwing the driving-mechanism out of or in gear, by the pawLor pawls G; attached to the driving-wheel, notched recess G, collar G lever G, and rod G", 'actingeither by means of the yoke G, or its equivalent, substantially as described.

3. The combination-of the bent axle B, bar '0, lever P, rod P, and wheel A, for regulating the height of the .cut-ter-bar M, substantially in the manner set forth. -4. The mode of suspending the rear of the detachable platform Q, by'means of the stirrup R, attached to the adjustable bar 0, substantially as setforth. i r

5. The arrangement of the bent axle B B, driving-wheel A, and wheel'Afl atteched to an adjustable bar,

0, substantially as described. I e i In testimony whereof, I have signed my name to this specification in the presence oftwo subscribing witnesses B. c; 1r. HATHAWAY.
