IMPROVEMENT IN MOWlNG-MACHINES.

Specification forming part of Letters Patent No. 159,277, dated February 2 1875; application filed December 19, 1874.

To all whom it may concern Be it known that we, DAYTON S. MORGAN and THOMAS MOTLEY, both of Brockport, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Harvesters, of which the following is a specification, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a plan or top view of so much of a two-wheeled hinge-j oint harvester (in which all our improvements are embodied in the best way now known to us) as is necessary to illustrate our invention. Fig. 2 represents avertical section therethrough on the line yy of Fig. 1. Fig. 3 represents a plan view, partly in section, of a portion of the gearing. Fig. 4 represents a detail view, partly in section, of the countershaft and its bearings.

The nature of our invention, the objects sought to be attained, and the subject-matter claimed hereinafter will be specified.

Two main driving and supporting wheels, A A turn freely on stud-axles a, projecting from sector-plates or radius-bars a, capable of swinging round a counter-shaft, O, mounted upon a main frame, 13, relatively to which the radius-bars may be adjusted and held in such adjusted position by means of holes in the frame," through which, and through corresponding holes in the radius-bars, pins may be passed to lock the parts together. A seat, D, for the driver is mounted upon the main frame, as usual, and a tongue, E, projects from said frame. The foot-board d is secured to the tongue. The counter-shaft 0 turns in pipe-box bearings c, resting in sockets in the arms I) b b of the main frame. The radius-bars a are mounted on the projecting ends of these pipe-boxes, thus relieving the countershaft from strain. The boxes are made in sections the better to enable the counter-shaft to be removed or inserted. A tubular drag-bar or coupling-sleeve, F, is pivoted upon the counter-shaft, its upper end being bifurcated, and its forks ff provided with eyes, which fit on shoulders on the pipebox bearings above mentioned, whereby the strain is taken from the counter-shaft. The coupling-sleeve is divided longitudinally in order the better to admit of. the removal or replacement of the crank-shaft which is inclosed therein. A shoe, H, is pivoted upon the coupling-sleeve in a well-known way, and a finger-beam, L, is secured to this shoe. A coupling-arm or brace-bar, G, is pivoted in rear to the shoe, while the forks g of its front end embrace a collar on the pipe-box bearings 0, thus preventing strain on the counter-shaft. A drag-bar, J, extends from the finger-beam outside of and around the inner driving-wheel A, being curved inward in front thereof, and pivoted upon the reunited arms or forks ff of the coupling-frame. The finger-beam is thus securely braced against lateral strains, while free to rise and fall, swinging around the counter-shaft as a center, and also swing around the crank-shaft, so as to allow the divider end to rise or fall freely to conform to irregularities of the ground. The rear end of the coupling-frame is sustained by a casterwheel, K, mounted on an arm, is, projecting therefrom. An internal spur-wheel, A, on each driving-wheel drives a corresponding pinion, c, capa le of moving freely endwise on the counter-shaft, and provided with a feather on its outer face, which feather engages with a transverse pin on the countershaft when the machine is advancing, but throws it out of gear when backing. Springs t, acting through pivoted arms '5 which bear against the pinions, tend to keep them in gear. Links 7? connect these spring-arms t with a shipping-lever, I, pivoted on the main frame. A bevel-wheel, N, on the counter-shaft drives a corresponding pinion, n, on a crank-shaft, N, which drives the cutters by a crank and pitman, as usual. The cutting apparatus and couplingframe may be raised, lowered, or suspended at any desired elevation by means of a chain, 0, hand-lever O, pawl 0, and detent 0 of any usual well-known construction.

We claim as of our invention- 1. The combination of the skeleton main frame, the counter-shaft mounted in pipe-box bearings therein, the forked coupling-sleeve pivoted on the pipe-boxes, and the similarlypivoted brace-bar, these members being constructed and operating in combination, substantially as set forth.

2. The combination of the skeleton main frame, the counter-shaft mounted in pipe-box bearings therein, the forked coupling-sleeve pivoted on the pipe-boxes, the finger-beam hinged to the coupling-sleeve, and the dragbar secured to the finger-beam in rear and pivoted on the coupling-sleeve in front, these members being constructed and operating in combination, substantially as set forth.

In testimony whereof we 118KB hereunto subscribed our names.
