To oncernn v i Kingston, in the .county` of Washington-i :and Statie of: Rhode Isl-andy' have infented Im- AMy A'i'iivelnthin"urelates to fmowin gand reap-` ing machines, Aand 'has patticularrefe'renceto r the" construction and `arrangeinent1- of the dri-v- .ing-wheels; ratchets,fand"pawls, gearing, carl-V riageirame; and"cutterdiarcon'neetions; 1; n

"ilhe :drawings represent 1such parts vof `the `machineland mechanism as arenece'ssary for clearly understanding `.my improvements.

G in the drawings denotes the main axle, mounted upon two wheels, b c. Upon one end of the axle is suspended the bearing-plate or hanger d, in which is journaled the shaft e.

rIhis shaft e passes through a sleeve, r, and carries at its rear end a bevel-pinion, s, which meshes into and is drivenby a bevel-gear, u,

on a counter-shaft, lv. i,

i At thefront end of sleeve r is hung the i shoe j', which has xed `to it and supports one end of the finger-bang, uponwhich recipro-` i cates thecutter-barfh, carrying the cutters t', playing between and through the slots in the rear ends of thevngers It.v The front end of the shoeif is hung from `the opposite end of the axle G Vby meansof `a link, l. Atthe front end of the shaft, e isa crank-wheel,m, from which extends? a wrist-pin, n, which plays in and reciprocates `a box, o, sliding in a vertical slot, p, in a slot-plate, q, projecting up from the end of theA cutter-bar.`

\ I am aware that frictionrollers havebeen used onwrist-pins'; bntthe employment of this box, increasing the bearing-surface, renders the parts more enduring and insures Roye-Meur 4N Aanv Ras; 7

` a2, `whose ,periphery lfits and islcapable ofretation within itheinner :surface `of tgheyflanga and whose inner. surface is an internal gear. y Each-.endof -ithe shaft fv- `carries,,a piniongl, that meshesinito the teelt @of Y.the 2gear-ring in 'the adjacent wheel. Y

Onthe outeror `peripllral surface of each ring is a series of ratchetnotches, c, with any one of which the tooth of a spring-pawl, d2, may engage, this pawl extending through a slot, e2, in the hub-flange z, as seen at (l, so that, as the wheels run forward, the pawls turn the gear-rings with the wheels, While, if the wheels run back, the pawls can slip over the ring without imparting rotative move- `ment thereto. As the gear-rings are rotated by the wheels their teeth drive the pinions b2 and impart rotation to the shaft c. The bevelgear u is not xed upon this shaft, but` turns loosely thereupon when not clutched thereto.

On the inner side of the bevel-wheel are clutchteeth f2, and on the shaft v isa sliding clutch, g2, operated by a clutch-lever, h2, the

with it. When the clutch is slid up against the clutch-teeth of the bevel-gear u, the rotation of the shaft v, effected by the gear-rings, drives the bevel-gear, whose rotation drives the bevel-pinion and the crank-shaft. When the sliding clutch is thrown away from the clutch-teeth of the bevel-wheel, the wheels drive the shaft t without imparting rotation to the bevel-wheel and crank-shaft, and', by

throwing the pawlsl2 up from the periphery clutch sliding along the shaft, but turning' of the gear-ring, the wheels will rotate without imparting movement, except the forward movement ofthe carriage, to any of the mechanism.

To hold each pawl out of connection with its ring, it is formed with a point, i2, in rear of its fulcrum, and by pressing up the pawl the spring bears upon this point, throwing it forward and the point of the pawl upward, as seen by dotted lines at C. Either or both wheels may thus be thrown into or out of connection with the gearing mechanism.

By making a hub shell or box, as shown, for containing the gearing, such gearing is shielded from all foreign matter, and saved from much wear and from breakage.

The bevel-gear u might be placed farther out on the shaft c 5 but, by placing it close to one of the main wheels and incasing it on the disk, it is out of the way, and the machine is rendered very compact.

The cutting apparatus is shown as swinging upon the crank-shaft; but the finger-bar may be hinged to the shoe f, and a pitmanrod or link-connection be made between the crank-shaft and the cutter-bar. Usually each cutter is riveted to the cutter-bar; but, iustead of so applying the cutters, I bend the rear part of each, so as to make a socket or recess therein for the reception of the cutterbar, as seen at E and at k2, the cutter-bar being made dovetailing in section, and the cutter-plate being bent, so that its recess corresponds to or ts upon the cutter-bar, the cutters being slid upon the end of the bar, or the bar being sprung into those made with a recess, and the last one being secured by a head on the bar to keep them all in place.

By making the cutters with a recess, as

above, any one can be removed and replaced independently of the others, and they are self-fastening, and held without rivets. The bevel-wheels are shielded by casing attached to the stationary disks.

rIhe gear-rings may be cast to the flanges or to the spokes of the main wheels, made in the ordinary way, and left partly open but I prefer the above-described mode.

By adding a platform, rake, and other attachments, it can be changed from a mower to a reaper.

By the use of the hand-lever and chain attached to the bearing-plate or hanger d turning on the axle, the cutting apparatus can be raised to any desired height, and, when not in use, can be laid over horizontally, and rest upon the pole.

Having thus described my improved mower 2. The hubs at', constructed as described, in

combination with the gear-rings, as and for the purposes set forth.

3. In combination with the main wheels and gear-rings, the ratchets and pawls, arranged substantially as and for the purposes set forth.
