IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 122,432, dated January 2, 1872.

To all-whom it may concern:

Beit known that I, JOSEPH BOEDWELL, of Brockport, in the county ot' Monroe and State New York, haye'invented certain new and useful Improvements in Harvesters, of which the following is a specification:

My invention relates more especially to machines of the class known as two-wheeled'i'rontcut hinged-bar mowing-machine; and consists in certain improvements, hereinafter speciiic'- ally described, upon the machine for Which Letters Patent of the United States, No. 7 8,- 904, were granted June 16, 1868, toThOmas Welch. I

In the accompanying drawing of my improved mowing-machine, Figure 1 isa plan; Fig. 2, an elevation of the stubble side; Fig. 3, a similar view of the opposite side; Fig, 4, a similar view of a part of the tongue-frame and gearing-frame.

Two driving-wheels, A A', turn freely on an axle, B, which revolves in boxes c in the main or draft-frame C. A flanged collar, b, keyed fast on the axle, carries, pawls 19.', which take into ratchet-teeth a on the inner side of the hub of the VWheel A'` thus locking the wheel and axle together when moving forward, as is Well understood, but leaving them disconnected in backing. The pawls have no springs, but operate by gravity alone. The other driving-wheel A has a corresponding ratchet. Its flanged collar, however, is secured to an internally-geared spur-wheel D fast upon the main axle B. This wheel drives a corresponding pinion, E, on a counter-shaft, e, turning in a box, c', on the frame. A grooved collar, f, slides freely on this shaft when moved by the n shi ppin g-lever F, and a ratchet on this collar is thus thrown into or out of gear with a transverse pin on the counter-shaft. This collar f likewise forms part of the universal joint'g of the tumbling-shaft G, which turns with but moves freely en'dwise in the knuckle ofthe I second universal joint H, Which forms the connection' between the tumbling-shaft G andthe shaft h mounted in bearings in the frame I. This frame consists of a hollow casing, I, rocking.

shaft H', which latter drives the cutters by a These wheels crank and pitman, vas usual. and the crank-shaft are shown in dotted lines in Fig. 1, being inclosed by the casing. A seat, L, for the driver is mounted on the main frame infront of the axle, in order that his weight may counterbalance that of the gearthe main frame, as usual. A foot-board, L', for the driver is secured upon this tongue, as is also a bracket, M', having a stop, m, underneath it to limit the rising of the couplingframe. A link, N, pivoted to the couplingframe, passes upward through a slot in this Y bracket. A pin, passed through one of a series of holes in this link above the tongue, limits the descent of the COuplingframe, While leaving it free to 'rise when necessary. This link also holds the coupling -frame irmly against the stop when` moving from iield to field. The double-tree O is attached to a draftrod, o, hooked into a lug` on the coupling-frame, so that the pull of the team may tend to lift the coupling-trame and cutting apparatus and diminish its pressure upon the ground, and thus lighten the dra-ft of the machine. A lifting-lever, l?, mounted on the main frame, vibrates a sector-rack, P', carrying a chain, p, connected with the nger-beam to lift it. A swinging pawl, p', pivoted to the bracket M',

engages the teeth ofthe sector-rack and holds v the linger-beam at the elevation desired. A hook, X, pivoted on the bracket, takes' into a hole, a', on the guide Y of the cutter-bar, when the cutting apparatus is folded up close to the main frame, 'and serves to hold the finger-beam in its elevated position. A cap, 2, on thecasing I, protects the crank from being obstructed by cut grass and other things, and also forms that portion of the casing which abuts against the stop m to limit the ascent of the cou pling-frame.
