' IMPROVEMENT m HARVESTERS.

Specification forming part of Letters Patent No. 88,381, dated March 30, 1869.

T0 all'whom it may concern:

Be it known that I, WILLIAM F. Goonwm, of East New York, county of Kings and State of New York, have invented certain new and useful Improvements in Harvesting-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making a part of this specification, in which Figure l is a vertical section of a machine embracing my improvement, taken in line as a, Fig. 2. Fig. 2 is a plan view. Fig. 3 is a perspective View, showing the manner of attaching the cutting apparatus. Fig. 4 is a horizontal section of the same, and Fig. 5 shows a modification of means for connecting the cutter-bar and crank-shaft.

My invention relates to a novel construction and arrangement of the main frame of the machine; also, to a novel arrangement of the driving mechanism hereinafter described, and to the manner of connecting the cutting apparatus or fin ger-bar with the frame, whereby the usual bolts or fastenings are dispensed with, and the said finger-bar is adapted to be readily removed or replaced, as hereinafter set forth.

In the drawing, A represents the main axle of the machine, mounted on two independent driving-wheels, B B. G is the main frame, made in triangular form, as represented in Fig. 1, and cast in one piece, or made in sections, indicated by letters a, b, c, d, and E, and screwed or otherwise securely fastened together. The sections a b are made tubular, and the section 0 is made in the form of a circular box, provided with a removable disk or head. The portions 0 d are mounted upon the main axle, and form boxes, which unite the frame with the axle in such manner as to allow it to move or vibrate freely upon said axle as a center. The casing or box 0 serves to inclose a spur or worm wheel, D, which is keyed to and turns with the axle, and from which motion is imparted to a worm-screw and crank-shaft, F, mounted in bearings in tubular sections a and E, in a manner represented by the drawing. f is a pivotal bearing to one end of, the shaft F, formed upon or attached to an adjustable screw-head, a, in the end of part or section a of the frame, and by the adpendent upon the size justment of which the end pivotal bearing f may be adjusted, as desired, to compensate for wear. Shaft F is provided with an endless screw, shown at F, which may be made of any desired pitch, conforming to the pitch or obliquity of the teeth on the wheel D, with which it engages, and by means of which it may be rotated with any required velocity, de-

, of the worm-wheel and the pitch of the screw thread or threads on shaft F. The outer end of shaft F is armed with a screw, f, which screws into and secures the crank-wheel G thereon. The screw is so formed as that the rotation of the shaft serves to tighten the screw, and, as the shaft remains stationary during anybackwardmovement of the machine, owing to the connection of the drive-wheels with the axle by back ing-ratchets, the crank-wheel is always kept firmly screwed upon its shaft F. Section E is made in an angular form, and has a cappiece, E, provided with a hub, e, which forms apivotal bearingfor an annular coupling-piece, H, located in the socket formed between sections E and cap E, and adapted to turn upon a bearing orbearin gs in line or concentric with the crank-shaft F. The swinging end of couplingpiece H has an annular head or ring, H, provided with lips or flanges h, which extend each about one-fourth part (more or less) of the circumference of the annular head, and are arranged upon opposite sides thereof. A hub or sleeve, 1, of corresponding form, on the shoe J, or shoe-standard I, fits over the head or sleeve H, and is provided with lips or flanges 6 corresponding to those on sleeve H, which enter behind the flanges h, and serve to unite the shoe J with the coupling H. The flanges h z are so arranged, relatively to each other, that by turning the sleeve 1 ninety degrees, or thereabout, upon the sleeve H, the flanges will pass by each other and permit the removal of the shoe and of the cutting apparatus or finger-beam K attached thereto. The pitm an passes through sleeves H I, which are enlarged sufficiently to allow the required play of said pitman, and is connected at one end to a wrist-pin or crank-wheel, G, and at its opposite end, by a ball-and-socket joint, with the lug or standard L on the sicklehead or heel end of sickle-bar M. Instead of the pitman the heel of the sickle-bar may be extended, so as to pass through sleeves H I,

and provided with a swiveling yoke-standard,

L, as represented in Fig. 5, in which the crankpin may work, to give the required reciprocations to the sickle. The tongue or tongue-plate N, which carries the drivers seat and liftinglever, arranged in any usual or desired manner, is hinged or connected, by a sleeve at its rear end, with the main axle, and may be adjusted laterally thereon for overcoming side draft, and is held at any desired point by sliding collars and set-screws O 0.

It will be seen from the foregoing description that the cutting apparatus may be readily adjusted to any desired height or set at any required angle without disturbing the workin g relation of the driving devices. The frame,

also, may be swung underneath the axle to change the machine from a front to rear cut, and vice versa, the connection of the cutting apparatus therewith being such as to permit these changes, while maintaining its proper working relation thereto, and to the surface of the ground, in a manner that will be readily understood without further description.

- Parts of the machine not particularly referred to may be constructed and arranged in any usual or desired manner.

Having now described my improvement, what I claim as new, and desire to secure by Letters Patent, is

1. A main or cutter frame, which vibrates about the worm-wheel shaft as a center, provided with bearings for a worm-screw shaft arranged tangentially to the worm-wheel.

2. A worm-wheel on the main axle, in combination with a screw crank-shaft, whereby motion is communicated directly to the cutters without the interposition of other gearing.

3. Mounting therear end of the worm screw shaft, or that end opposite the crank or crankwheel, on an adjustable pivot-bearing, as set forth.

4. The screw on the forward or crank end of the shaft F, operating in combination with the crank-wheel as described.

5. The hinged coupling H provided with the flanged annular head H, for the purpose set forth.

6. The flanged rings H I, or their equivalents, on the coupling and shoe or shoe-standard, for uniting the cutting apparatus and main frame, substantially as described.
