HARVESTER.

SPECIFICATION forming part of Letters Patent No. 250,271, dated November 29, 1881.

Application filed May 24, 1880. (No model.)

To all whom it may concern Be it known thatl, JOHN P. MANNY, of Rockford, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Harvesters, of which the following is a specification.

The present invention has reference more particularly to the construction and arrangement of the gear mechanism of a harvester, the object being to combine compactness, simplicity, and strength.

The invention is fully illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a one-wheeled front-cut harvester embodying theinvention, the platform being removed. Fig. 2 is a plan of a portion of the gear mechanism and of the parts immediately connected therewith. Fig. 3 is a side elevation of the parts lying on the stubble side of the vertical plane,indicated by the dotted line as m in Fig. 2. Figs. 4 and 5 show the backing-ratchet by means of which the main gearwheel and the driving-wheel may be locked together, Fig. 4. showing the pawls and their springs seated on the face of the gear-wheel, and Fig. 5 the ratchet-teeth in the hub of the driving-wheel.

Referring to these drawings more in detail, A represents the draft frame or pole of the machine. B is the main gear-frame; O, the driving-wheel; D,thegrain-wheel; E,the main gear-wheel; F, an inclined standard for supporting the rake mechanism and mounted on the bracket G; H, the rake-driving shaft supported on such standard, and I is a countershaft, and K crankshaft for driving the cutters.

The driving-wheel (J and the main gearwheel E are mounted upon the same axle,,and are made capable of being locked to each other, at the will of the operator, by means of an interposed clutch mechanism. The clutch mechanism here shownis a well-known form of backing-ratchet, operated by means of a shippingring, L, and being well known in the art does not require to be specifically described. It is plain that the pawls of this clutch mechanism may be placed on either the gear-wheel or the driving-wheel, as may be found most convenient, the ratchet element of the combination being, of course, placed on the other wheel. If the axle be fixed in its bearings both wheels must be loose on the axle; but if the axle be free to turn in its bearings one of the wheels must be fast on the axle. However the apparatus be built in this respect, the proper adjustment of the shippingring will lock the two wheels together for the forward movement of the machine, or by the simple shifting of the shipping-ring the cutters will be permitted to remain at rest while the machine is advancing, and in either case the machine can be backed without revolving the gear-wheel and working the cutters. This capacity of the machine, however, being old in the art, is not claimed as specially characterizing the present invention.

Upon the main beam of the gear-frame of the machine, which gear-frame is also the main frame, is mounted the bracket G, and this bracket is so constructed as to serve at the same time both as a bearing for the axle of the driving-wheel and as a support for the inclined standard F, which is to carry the rake mechanism.

The main geanwheel E consists of an ordinary spur-wheel with a bevel-face gear out upon one of its sides, the teeth upon its periphery being designed to mesh with the pinion upon the counter-shaft I, and those composing the bevel-face gear meshing with the bevel-pinion on the inclined rake-driving shaft H. This form of gear-wheel, when used in combination with a counter-shaft and a rake-driving shaft geared directly thereto, enables these parts to be brought into comparatively small compass with great simplicity of construction and corresponding strength, and by making the gearwheel and the pinions of these shafts to overhang the main frame on the stubble side, as shown, the weight is transferred as far as possible to the driving-wheel, where it becomes efficient in securing the proper traction, and thus largely relieves the frame from the weight that would tend to sag it. This position of the main gear-wheel relatively to the main frame is secured without unduly increasing the length of the axle by utilizing the backing-ratchet as a direct clutch mechanism between the driving-wheel and the gear-wheel.

The height of the finger-beam M is regulated as follows: The draft frame or pole is hinged to the forward end of the main frame, which latter has the capacity of rocking or vibrating form no part of the present invention.

on the main axle. Attached to the rear end of the draft-frame, at or near to the hinge, is a post or standard, N, which is connected by any suitable coupling-rod to the lifting-lever O, which lever is pivoted upon the rear of the main frame, and at as great a distance as possible behind the axle of the machine and still be within reach of the driver. By locating the post N close to the hinge between the draftframe and the main frame, the leverage of resistance, when it is desired to raise the fin gerbeam, is reduced to a minimum, and by placing the lifting-lever behind the axle it results that when the driver pulls upon the lever to raise the cutters he at the same time necessarily pushes down upon the rear end of the main frame, which will be found a more economical expenditure of power than if the'lever were mounted on the axle.

The lifting-lever may be provided, as shown, with the usual spring-pawl and ratchet.

Neither the rake mechanism proper nor the platform is shown in the drawings, as they These parts, however, are fully shown and described in other applications for Letters Patent filed contemporaneously herewith, and in which they are made the subject of special claims.

What is claimed as new is- 1. The combination, in a harvester, of a main frame, an axle projecting over the stubble side thereof, a main gear-wheel mounted on the projecting part of such axle, between the main frame and the driving-wheel mechanism, by which said gear-wheel is adapted to drive both the rake and the reel-bats, and backing-ratch: ets and shipping mechanism interposed between such gear-wheel and the driving-wheel, for the purpose described.

2. The combination of the rake-driviu g shaft, the counter-shaft carrying the gear for driving the cutters, and the main gear-wheel mounted on the main axle, and provided with both a spur-gear and a bevel-gear for operating thev counter-shaft and the rake-driving shaft, substantially as described.

3. The combination, in a front-cut harvester, of a main frame which rocks or vibrates about the main axle, a draft frame or pole hinged to the front part of such frame, a lifting-lever mounted on the rear part of the main frame behind the axle, a rod or link connecting such lever with a post mounted on the rear part of the draft-frame, at or near its hinge, and a drivers seat arranged in rear of the axle and at a point in advance of the lifting-lever, substantially as shown and described.
