lM PROVEM ENT IN HARVESTER-DROPPERS.

Specification forming part of Letters Patent No. 104.953, dated July 5, 1870.

I, DAVID S. HARNER, of Xenia, Greene county, Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a specification:

Nature and Object of the Invention.

My invention relates, principally, to an improved apparatus for depositing the cut grain in a swarth sufficiently distant from that which is left standing to be out of the way of the machine in the succeeding cut.

General Description with Reference to the Drawmy.

Figure l is a perspective view of a machine embodying my improvements, the dropper being swung open and the cut-off dropped. Fig. 2 is an enlarged top view of the main frame without the platform. Fig. 3 is a perspective view of a portion of the machine, showing the dropper in its closed position to receive the grain and the cut-off elevated so as to stand clear of the falling grain. Fig. 4 is a vertical section through the ground-wheel in the plane of the counter-shaft. Figs. 5 and 6 are, respectively, vertical and horizontal sections of the pitman. Fig. 7 is a transverse section of the guard or finger-bar and the cut-off in position. Figs. 2, 4, 5, 6, and 7 are to enlarged scales.

A main frame, A, suitably constructed for the support of the various operative parts, has firmly affixed to it axles B. whose extremities are provided with sleeves O, of steel or chilled iron, which constitute the spindles upon which the wheels D revolve, and which, on becoming worn, can be removed and replaced with new Affixed to each groundwheel D, and concentric therewith, is an interior gear-wheel, E. The wheels E mesh with pinions F, which, revolving freely upon a counter-shaft, G, journaled in the main frame, operate through the medium of a customary ratchet movement, H, to rotate said shaft by any forward rotation of either ground-wheel. Also mounted loosely upon the said shaft Gis a bevel spur-wheel, I, which, in the operative condition of the machine, is compelled to revolve with said shaft by its engagement with a sliding clutch, J, which rotates with said shaft, but which, when the machine is not re quired to operate, can be liberated by the act of sliding back the clutch, and in this condition of these parts the machine may be wheeled or driven about from place to place without working the cutter.

Pivoted to the counter-shaft G and to a bracket or projection, A, from the main frame is a gravitatin g frame, K, to which the fingerbar It is pivoted. This pivoted connection is madeby the shoe L, which, being bent upward at both ends, encircles in two places the rod K of the gravitating frame. The rear portion of the shoe L, being carried upward, forms the reel-post M, which post is forged or cast in one piece with the shoe L. The finger-bar It hasan elevated portion or guard, is, to which the fingers are attached, or in front of which they project, and behind which the prongs a of my dropper N rest in their receiving-position.

Projecting perpendicularly from the head of the dropper is a shaft, 0, whose lower end is stepped in a lug, P, and whose upper portion occupies a slot, q, in a bracket, Q, projecting from the reel-post, and terminates above said bracket inacrank, 0. The slotqis L-shaped, so as, in the receiving position of the dropper, to hold the latter up behind the guard, and in its discharging position to allow the tips of its prongs to drop upon the ground and its load of grain to slide easily off. A projection, n, from the dropper-head, impinging against the reel-post, serves to limit the outward sweep of the dropper. Pivoted to the reel-post, in the manner shown, is the arm B of my cut-off S.

J o urna-led athwart the frame is a rock-shaft, T, from which depends an arm, U, from which a cord, "at, passes around a' pulley, u, in the head N of the dropper. Projecting upward from the rock-shaft T is a perforated arm, V, from which a cord, '0, is carried to the crank o of the dropper, and from which another cord, r, is carried to the upturned heel r of the cut off arm. Treadles t t projecting from the rock-shaft T, conveniently for the use of a person occupying the seat, enable such person to simultaneously open the dropper and close the.cut-ofi", (see Figs. 1 and 2,) and'again to simultaneously close the dropper and open the cut-off. (See Fig. 3.)

In order to enable the operator to adjust the parts so as to properly execute these movements, one or both of the arms U and V may have a series of perforations, as shown, for the reception of the cord. In order, however, to enable the operator to work the dropper by hand, when he may desire to do so, there may be provided an arm, X, connected by rod Y with a lever, Z.

The pit-man which conveys motion from the wrist l to the knife 2 terminates at one end in a hook, 3, which occupies an eye, 4, in the heel of the knife, and slack motion of said hook in said eye is prevented by means of a sleeve or thimble, 5,which is set and held up against the outside of the knife-heel by means of a nut, 6, and which is held against rotation by means of a set-screw, 7, whose point enters a cavity, 8, in the pitman-rod. The other end of said rod screws into a two-eyed coupler, 9, and is made fast to any desired adjustment by a pinch-nut, 10. This enables the rod to be lengthened or shortened, as may be desirable for accurate and proper cut of the sickle. The coupling-head 9 receives the wrist 1 into one of its eyes 11 or 12, and when one eye has worn slack the other eye can be placed upon the wrist. When both eyes become too much worn for efl'ective use, the old coupler may be replaced by a new one.

The gravitatin g platform K may be elevated and depressed by means of a link, 13, attached to the short arm of lever 14, the latter being maintained at any desired position by pin 15,

occupying either of the perforations oficurved bar 16. Motion is communicated from bevelwheel I to the wrist 1', which operates the knife-pitman,by means of pinion 17 and shaft 18. The shaft 19 of reel 20. carries a scored pulley, 21, which is rotated by a band, 22, that passes around a large pulley, 23, the latter being secured to one of the ground-wheels, I). The reel-shaft is maintained at any desired ele: vation upon post M by the set-screw 24.

' Claims.

3. In combination with the laterally-swing ing dropper N n n, the vertical swinging cutoff R 'r S, both being operated simultaneously from the rock-shaft T, in the manner substan tially as set forth.

In testimony of which invention I hereunto set my hand.
