FREDERICK NISHVITZ, OF BROOKLYN, NEWT YOBK.

ArnN'r I IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 46,2188, dated February '21, 1865.

, do hereby declare that the following is a full,

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being hadfto the accompanying drawings, forming part of this specification, in whioh- Figure l represents a side view of my invention; Fig. 2, a plan or top view of the same 5' Fig. 3, a longitudinal section of a portion of the same taken in the line :c x, Fig. 2, Fig. 4,

a transverse vertical section of the same taken in the liney y, Fig. 2; Fig. 5, a detached view of one of the sides of the socket which receives the finger-bar.

Similar letters of reference indicate` like parts.

This invention relates to a new and improved sickle-driving mechanism, hereinafter fully shown and described, whereby I am enabled to obtain a requisite speed by a very compact arrangement of parts. I

The invention also relates to an arrangement of a lever applied relatively with the draftpole, in the manner hereinafter described, so as to cause the outer end of the finger-bar to be elevated when the inner end 'of the same has been elevated a certain height. The invention also relatesto a new and improved shoe, arranged and applied in such a manner' as to support the front part of the machine and partially sustain the finger-bar, so that it will run lightly over the surface of the ground, and at the same time serve to protect the pitman which drives the sickle.

The invention further relates to anovel manner of attaching the finger-bar to the main. fra-mc of the 4machine, whereby a strong and durable joint-connection is obtained.

A represents the main frame ofthe machine,

- which may be of rectangular form and mountinner side of its rim. The axle Cpasses loosely through the center of the plate D, and on the axle there is firmly keyed an arm, E, which projects at equal lengths from opposite sides n of the axle, and is provided near each end with a pin7 b. These pins project atright angles fromthe arm, and a pinion, F,lis tted I loosely on each pin, said gear-ings gearing into the teeth c of the plate D. The pinions F F are of equal dimensions, and they both gear into a pinion, G, on a collar, H, which is placed loosely on the axle C and allowed to turn freely upon it. The outer end of the collar H isprovided with ratchet-teeth Iff. (Shown in Fig. 2.)

I is a bevel-toothed wheel, which is fitted loosely on the axle C, and is provided with a hub, c, which has ratchet-'teeth WQ, made on its end opposite the teeth Z1* of the collar H. The wheel I may be connected with the collar H and disengaged from it, as desired, by means of a lever, J, provided with cams or any suitable or equivalent device for moving said wheel. The wheel I, when connected with the collar-H, is in gear with a bevel-pinion, K,

'on the inner end of a shaft, L, placed longitudinally on' the main frame A, and having a crank-wheel, M, on its front end, to which the pitman N is attached which drives the sickle.

By this arrangement it will be seen that when l the machine is drawn'forward the pinions F F of the arm E will be rotated. As the arm E rotates in consequence of said pinions gearing into the teeth a of the stationary plate D, and as the pinions F F both gear into the pinion G of collar H, motion is communicated to said A collar, and the latter will rotated the bevelwheel I when the hub c is engaged with collar H, and the shaft L rotate through the medium Yof the wheelI and pinion K. By this means I am enabled to give a requisite speed to shaft L by a very compact arrangement of gear, for in addition to the speed obtainedby the multiplication of the gear I obtain that of thev axle C, which, as the gear1V receives its motion from it, of course makes up toward increasing the speed of the shaft L.

of the finger-barO', which is attached to the main frame by a joint of peculiar construction, as follows: To the mainframe there are secured two pendants, P P, which are slightly inclined, and have each a semicircular groove, g, made in `them at their lower ends, as shown clearly in Fig. 5, and the finger-bar O is provided at 4each side of ,its inner end with a semicircular elevated a Acertain distance the inner end of the lever M will be brought in contact with the draft-pole N* and the outer end of the fingerbar automatically raised.

S represents ashoe composed of aflat metal I bar curved or bent in seinicircular form at its front part, so as to extend over on the upper part ofthe main frame A, the back part of the shoe being curvedupward and secured to the rear pendant, P, to which the finger-bar is secured. This shoe serves to support the iingerbar, causing it to run lightly over the surface of the ground, and at the same time it protects the lower part of the pitman N.'

To the back part of the draft-pole N there is attached, by a joint, T, a bar, Il, on the back end of which the drivers seat V is secured.

This bar U 'is supported from the main frahe A by a bar or spring, W, whichfismconnected by joints i z' to the bar U and the main frame. This elastic bar or spring, while serving as a support for the seat-bar U, also adniits of the weight of the driver assisting in elevating the front part ofthemain frame A, and relieves the team of downward pressure on the draftpole. Y

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the stationary toothed plate D, pinions F F, attached to the ends of an arm, E, irmly'keyed on the aXle C, with the pinion Gon the collar H, placed loosely on the axle,` and the bevel-wheel I,also placed loosely on the aXle and connected with the collar H, all arrangedV to operate substantially as and for the purpose set forth.

2. The lever M', applied to the main frame A, and in relation with the draft-pole N*, as shown, and connected to the'iinger-bar O by a chain, f, all arranged to operate substantially as and for the purpose set forth.

8. Connecting, the linger-bar O with the main frameA by means of a joint composed of the semicircular recesses g g inthe pendants P P andthe semicircular'proj ections hh on the sides of the nger--bar O, substantially as described.

4. The shoe S, arranged and applied to the main frame A relatively with the pitman N' and nger-bar O, to operate substantially as and for the purpose specified.
