IMPROVEMENT 1N HARVESTERS.

The Schedule referred to in these Letters Patent and making part of the same To all whom fit may concern Be it known that I, WILLIAM F. GOODWIN, vof Metnchen, county of Middlesex, State of New Jersey,

have invented certain new and useful Improvements Among the objects sought to be attained in the construction of harvesting-machines, have been a compact arrangement of gearing for operating the cutters, such as would readily permit its being inclosed or boxed up to prevent its being obstructed by dirt or other foreign matter, and the combination of the cutting apparatus therewith, in such manner that, while the said cutting apparatus could conform freely to the surface of the ground over which it .was drawn, all cramping or binding of the gearing or of the parts coupling the same with the sickle-bar should be avoided.

My invention relates to a novel construction and arrangement of parts for accomplishing these objects, and will be fully understood from the following description, in connection with the drawings, in which- A A represent the main, ground, and drive-wheels mounted loosely on a common axle, B, and connected thereto by backing-ratchets at a.

C C1 represents the main or gearing-frame, made by preference in two parts, which are perforated to receive the axle B, and are fastened together at their ends by horizontal bolts passing through them.

The part Cl of the frame has a tubnla'r arm or sleeve, C2, attached or cast with it, the forward or swinging end of which is provided with a' yoke, C, from which a brace, O, extends obliquely to the axle B, and is connected therewith by a sleeve, Gi'.

The portions C Cl ofthe fra-me inclose the gearing, arranged as follows, viz:

D is a straight spur-wheel mounted upon and keyed to the axle B.

E is a second short shaft mounted in frame O Cl, in a pbsition parallel with the main axle B, upon screw pivot-bearings El, which pass through the sides of the frame and are adjustable therein.

The ends of the pivot-bearings E1 are pointed or conical, and fit into corresponding sockets in the ends ot' shaft E,` as shown in g. 3, or the ends of the shaft may be pointed to match sockets in the adjustable bearings, as may be found most convenient.

By means of these adjustable pivotal bearings I can adjust the mesh of spur-gears D5 d, thereby compensating forA the wear of the cogs upon said gea-rs, thus adding materially to their durability.

The bearings or screws El, when properly adjusted, may be held by jam-nuts c.

The shaft E' has keyedto it at one end a spur-piuion,D, and at its opposite end a traveling arm, F, the outer end of which is armed with a short stud or shaft, on which is mounted a transmitting-wheel or pinion, D2, which travels with the arm li, and meshes with and receives motion ou its`own axis from a stationary internally-toothed rim, D, 'cast with or attached to the portion C of the frame.

D4 is a straight pinion mounted loosely on shaft E, in the saine vertical plane with the concentric internally-toothed rim D:= and transmitting-pinion D2, the latter engaging with said pinion Di, and imparting motion thereto.

D`` is a bevelfwhcel, cast with orrigidly attached to pinion Di, from which, motion is imparted to a bevel-l pinion 011 the crank-shaft, and thence to the sickle-bar in the usual manner.

The crank-shaft is extended beyond the wrist to which the pitman is attached, in order that it may be supported at its lower end.

G Grl are concave lids, or cap and bottom, made of a depth which, added to the depth of the frame,`

is suiiicient to iuclose the gearing, and are hinged at one end to the frame, as shown in fig. 2.

q y are spring catches or clasps, which serve to hold the cap G and bottom G1 in their closed position.

The crank-shaft is` mounted in the sleeve C2 of the frame, and at its lower or forward end is supported against the end-thrust consequent upon the employment of bevel-wheels for driving the same by means of an adjustable screw-pivot, h, mounted in a sleeve or arm of yoke C3.

I is a coupling-piece or frame for connecting the cuttingapparatus with the main frame, said piece or frame consisting of a vertical annular hub or ring provided with horizontal arms which embrace the yoke O3 between them, and serve, in connection with half boxes Il, -to clasp the sleeve C" of the frame onopposite sides of saidyoke, thereby forming the joint of the cutting apparatus on a line coincident with the axial center of the crank-shaft.

, rlhe heel end of the linger-bar has au upright standard, J, attached to it, providedwith an opening corresponding to that through the annular 'hub of coupling-piece I, and with anged lips and grooves matching corresponding grooves and lips formed ou the adjacent 'face of the annular hub of the coupling I, for attaching the said finger-bar to said coupling, and through said coupling to the main frame, as described. Au upright spring, K attached to the shoe L, or to the heel end of the finger-bar M, is provided 'at its upper end with a pin or spur, at k, which enters a hole in the annular hub I, and serves to hold the cutting,r apparatus at the desired angle of presentation to the ground, and to prevent the rotation of the same on its longitudinal axis or hub I.

The cutting apparatus and shoe L may be of any desired or usual construction.

In practice, however, the lat-ter will be made of a width suiiicient to extend underneath the forward or vibrating end of the main flame, and thus to serve to protect the latter and the crank-shaft and wheel from injury from obstructions inthe path of the machine.

Having now described my invention, What I claim as new, land desire to secure by Letters Yatent, is-

1. The arrangementof the stationary internallytoothed rim and planetary gear about a secondary shaft or pinion-shaft lying parallelfwith the main axle of a harvesting-machine, as set forth.

2. The combination in a harvester of the shaft E,

5. The annular hub or coupling-piece I, havinfar arms' provided with half-boxes Il, as set forth, in combination with yoke C3, sleeve O, and standard J.
