IMPROVEMENT N HARVESTERS.

Specification forming part of Letters Patent N 0. 46,488, dated February 2l, 1865 Reissue No. 3,496, dated .rune 8,1869. v

To all whom 'it may concern:

Be it known that I, FREDERICK N IsHwITz, of Brooklyn, in the county of Kings and State ofNew York, .have invented Y certain new and useful Improvements in Harvesters, of which the following is a full, clear, and eXactdescription. f

My invention relates to that class of harvesters having' two driving and supporting wheels and a finger-beam hinged to the main frame.v Y

The object of the iirst part of my invention is to liftthe divider fend of the linger-beam higher than its heel end, in order to pass obstructions with greater facility; and the improvement consists in a novel method of combining a lifting-lever, a vibrating tongue or draft-flame, a vibrating gear-frame, and a iinger-beam hinged to the gear-frame with a vibrating tilting lever interposed between the two frames, and connected with the fingerbeam by a iiexible or jointed connection.

The object of the'next part of my invention is to enable the driver to preservethe proper relation of Vhis seat to the lifting-lever, notwithstanding the brations of the tongue and gearing-frame 5 and the improvement consists -in a novel method of combining a vibrating gear-frame and a vibratingdraft-frame with a driver-s seat mounted on a supportingbar pivoted on the draft-frame and connected with the gearing-frame by a pivoted link.

.The improvement further consists in a novel lmethod of combining a vibrating gear-frame, a vibrating tongue, and a vibrating drivers seat with a lifting-lever which vibrates the frame and drivers seat simultaneously.

The object of the next part of the invention is to balance the machine on its supportingwheels; and the improvement consists in a novel method of combining a vibrating gearframe and a vibrating tongue or draft-frame with a drivers seat supported partly on the tongue and partly on a link connected with the main frame, and adjustable backward or forward relatively to the axle, to adapt the machine to drivers of different weights.

The accompanying drawings represent all my improvements as embodied in a machine similar in its general outlines to the one shown -States No. 19,37 7 granted day of February, 1853.

DIVISION B.

and described in' Letters Fat-ent of the United to me on the 16th Figure l representsa Fig. 2 represents a vertical longitudinal section through the ma'- chine at the line aux of Fig. l, lookingl toward the divider side of the machine. Fig. 3 represents a view in elevation of the rear pendant detached, as seen from the front. Fig. et represents a vertical transverse section through the machine at the line z z of Fig. l,.looking toward vthe rear, and showing more particularly the method of lifting the divider end of the linger-beam. Fig. 5 .is a view showing the' drivers seat and its connections with the main frame and tongue.l 1 In this instance the two driving-wheels A A are shown as mounted loosely on a common axle, B, with which they are connected by backing-ratchets of well-known construction. The axleB revolves loosely in suitable bearings on the gearing-frame C. An internallygeared spur-wheel, D, is secured upon a concave disk, d, fixed upon the gearing-frame in such manner that the spin-wheel D is concentric with the axle B. An arm, E, Xed upon, revolving'with, and projecting on each side of the axle B, carries spnr-pinions E', revolving freely on pins e, and meshing on one side into the spur-wheel D, and on the other into a spin-pinion, F, iiXed on a collar, f,turning freely on the main axle, and connected by la y, also revolving' loosely on the axle B, and carrying' a bevelwheel, G, driving a corresponding' pinion, h, 011 a crank-shaft, H, which drives the cutters I by a crank and pitman, hf', in the usual way.

The mechanism is thrown into and out of gear by means of a shipping-lever, G, provided' with a cam-yoke fitting over aiiange on the collar g. A tongue or draft-frame, J, is hinged to the main frame by a pivot, j, so as to vibrate freely vertically. A loop, K, on the front of the gearing-frame encompasses the tongue, acts as a stop to limit its descent below a given point, and sustains it against lateral strains, as in turning.

A lifting-lever, L, is pivotedy on the tongue, and is connected with the forward end of the plan or top view of ure of the cutting apparatus gearing-frame by a cord or chain, l, passing over a pulley on the tongue. A pawl, L',piv oted on the hand-lever, takes into a ratchetplate onthe tongue and holds up the gearingframe, as described in my patent of 1858, hereinbefore referred to. l

A seat, M, for the driver isV mounted on an inclined arm, M', pivoted at m to lugs on the draft-frame. This arm M is supported at a point intermediately between the pivot and the drivers seat by a link, m', vpivoted both to the bar and to the gear-frame behind the main axle, as shown by the dotted lines in. Figs. 1

' and 2. The pivots of the tongue, the inclined i arm, and of the connecting-link thus forni a sort of parallel-rule joint, which compensates for the vibrations of the tongue and gearingframe, and enables the driver to maintain his proper relation to the lifting-lever, instead of his seat rocking backward and forward, as it would do if mounted directly upon the gearing-frame. As the seat is located behind the main axle, the weight of the driver tends both to lift the tongue and to depress the rear end of the gearing-frame, thus diminishing the presson the ground, and causing the machine to run more lightly. The link m1 is connected both with the arm M' and with the frame by slots and set-screws m2, as shown in Fig. 5, which permit it to be adjusted` backward or forward, and thus balance the machine. l

y The iinger-beam N is securely fastened to a socket, N', provided with semicircular pivots n, iitting in sockets 0in pendants O O', rigidly secured to the inner front corner of the gearing-frame, and connected by a clamping-bolt, o.

A metallic shoe, P, is firmly secured to, and4 projects in advance of, the front pendant O. The finger-beam is thus free to 'vibrate vertically on its pivots, while the shoe P is fixed. The iinger-beam may likewise readily be detached from the main frame.

A supplementary guard-shoe, Q, composed of a iiat bar of metal, is secured at its front end to the main frame and curved downward, and its rear end is secured to its rear pendant As this shoe is slightly elastic, it relieves the pressure of the cutting apparatus upon the ground, and protects the pitman from being clogged by the cut crop; cutters from falling out of the guards while the finger-beam is folded up.

A lever, R, is pivoted to vibrate vertically on a pivot, r, on the gear-frame. This lever iied.. also prevents the f is arranged in the same vertical plane as the finger-beam, is interposed between the tongue and the gearing-frame, and its outerend is connected by a chain, r', with the inger-beam, at a point outside of its hinge. Consequently, when the gearing-frame is lifted by means of the hand-lever L, the tongue' depresses the lever, and thus tips up the divider end of the cutting apparatus. rlhe cutting apparatus may be folded up on its hinge until it rests against the main frame, in which position it may be held by a spring-hook, S. When thus folded up the entire cutting apparatus does not project beyond the outer face of the driving-wheel A, and the machine may, consequently, be driven through gates very little wider than the distance between the drivingwheels. j A

The operation of this machine being similarA to other machines of this class, it is deemed unnecessary to describe it here.

What l claim as my invention is l. The combination of 'the mam frame vi- V brating on the main axle, the tongue vibrating on the main frame, the nger-beam hinged to the main frame, and the lifting-lever mounted on the tongue, with the tilting-lever interposed between the tongue and gear-frame inv the same vertical plane as the inger-beam, with which it is also connected by a chain attached outside of the pivot of the iinger-beam, the whole being constructed for joint operation, as set forth.

2. The combination of a vibrating gearframe and a vibrating draft-frame with a drivers seat, supported on the draft-frame and connected with the gearing-frame by a pivoted l link; l y Y 3.v The combination of a vibrating gearframe, a vibrating tongue or draft-frame, and a vibrating drivers seat with a lifting-lever, L, the combination being and operating substantially as set forth. I j Y 4. The combination, substantially as set forth, of a vibrating tongue or draft-frame and a vibrating gear-frame with a drivers seat mounted on the tongue or draft-frame, and connected with the gear-frame. by an adjustable pivoted link, for the purpose specir.
