IMPROVEMENT IN HARVESTING-MACHINES.

Specification forming part of Letters Patent No. 49,501, dated August 22, 1865."

To all 'whom it may concern:

Be it known that I, HEWETT CHANDLER, of New Gloucester, in the county of Cumberland and State of Maine, have invented a new and Improved Grass and Grain Harvester and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specitication, in which- Figure l is a plan or top view of my invention; Fig. 2, a side sectional view of the same, taken in the line a: fr, Fig. l; Fig. 3, a front view of a portion of the same; Fig. 4, a detaohed side view of a catch or fastening pertaining to the same. j

Similar letters of reference indicate corresponding parts.

The invention relates to a novel and improved arrangement of parts for throwing the sickle-driving mechanism in and out of gear, as hereinafter fully shown and described.

A represents the main frame of the machine, which is mounted on two wheels, B B, the latter being placed loosely on their axle C.

To the front end ofthe main frame A, at its right-hand side, there is attached a pendant, D, which is slightly inclined outward from its upper to its lower end, and has the finger-bar E connected toA it by a joint, F, as usual in many harvesters.

G is the sickle, placed on the finger-bar E and arranged in the ordinary way, andhaving a connecting-rod, H, attached to its inner end, said rod being connected at its outer end to a crank-pulley, I, which is, at the front end of the shaft J, placed longitudinally on the main frame, and having a bevel-pinion, K, at its rear end, which gears into a bevel-wheel, L, on a shaft, L', at the back part of the main frame A. The inner end of the rod H, where it is connected to the sickle G, has an arm, M, secured to it, which projects upward, and has an eye, a, at its upper end, said eye being titted on a pin, b, which projects at right angles from a standard, N, at the inner end of the finger-bar. The lower end of the arm M is fitted loosely in the connecting-rod H, so thatit may work therein and admit of the free reciprocating movement of the 'sickle under the action of the rod H and crank-pulley I, and at the same time serve to suspend the inner end of the sickle, so as to preserve the latter from any undue pressure and friction under the oblique action of the connecting-rod. The eye ct is about on a horizontal line with the shaft J, as will be seen by referring to Fig. 3. Thus by this simple arrangement much friction is avoided in the operation of the sickle and thedraft of the machine proportionably'reduced.

The axle C has bosses N N upon it, provided each at their lower parts with a lip, c, and these lips are fitted in recesses d in blocks or beds e on the main frame A. (See Figs. 2 and 4.)

The axle C passes through oblong slots e in upright plates f at the outer sides of the blocks or beds e', to admit of a forward-and-backward movement of the axle when the bosses N N are turned. This is accomplished by having one of the bosses N provided with a handle, O, which is fitted in a socket,f", attached to the bearin g, and has a spring, g, hearin g against it, said spring having a tendency to press the handle O against or toward the upright plate `fof the block, on which the boss N', having the handle O attached, rests, said upright plate having a lip, h, at its upper edge pro` jecting inward.

By moving the handle O forward the axle` C will be moved in the same direction and bear against the front edges ofthe slots e e in the upright plates f f, the spring g pressing the handle O in front of the lip l1l to prevent a casual backward movement of the axle. By this adjustment of the axle C teeth at the inner peripheries of the wheels B B are made to gear into pinions it' on the shaft L and com-- The lips c on the axle C, resting in recesses v d in the blocks e', and employed, in combination with the lever O, to throw the pinions i t' in and out of gear, as explained.
