HARVESTER.

SPECIFICATION forming part of Letters Patent No. 354,397, dated December 14, 1886.

tNo model.)

To all whom t 'in/ay concern:

Be it known that I, FREDERICK Cook, a citizen of the United States, residing at Taylorville, in the county of Christian and State of Illinois, have invented certain new and useful Improvements in Harvesters, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in harvesters of that class known as low-down liarvesters, and is designed to produce a machine that may be lowered or raised in a vertical direction to adjust the cutting apparatus for heading or for cutting different lengths of straw, to obviate the excessive elevation of the grain to carry it over the drive-wheel. The peeuliarity ofconstruction also enters into the invention.

The above object, as well as the construction of the device, is set forth below in the description, reference therein being had to the anneXed drawings, in which- Figure l represents a perspective view -of the harvester; Fig. 2, a plan view of the same; Fig. 3, a rear elevation with the reel and drive-wheels removed; Fig. 4, an elevation of the grain end of the platform; Fig. 5, a detail elevation of one of the drive-wheels, and Fig. 6 a detail elevation of the front caster-wheel.

The machine is provided with two drivewheels, A and B, arranged preferably at the rear of the frame, but which may be placed at any convenient and practical point where the conveyer o'f the binding apparatus will not pass over them. One wheel may be used in place of two. Each of the wheels is loose on the axle O and carries it in one direction only by means of clutch D.

Pulleys E, carrying pinons Fform bearings for the shaft or axle C. The pinions F engage with racks G, secured to projecting thereon, with its pawl l and its connections to the small thumblever at the upper end of the hand-lever O, serve to operate the said shaft. A detaining-pawl, R, pivoted to the frame, prevents the backward turning of the shaft K duringthe reverse motion of thelever O, and this pawl is operated to discngage with the wheel N by means of a foot-lever, S, secured on the bridge T of the machine, in proximity to the seat.

Chains or ropes U pass from the pulleys E to the drums L and serve to turn the said pulleys so as to elevate the rear of the machine,

the lever O being used for the purpose, while the disengagement of both pawls from thef `the upper arm con nectedv to the chain or rope .X, it is evident that a rearward motion of the said rope will depress the wheel and raise the grain-receiving platform, while the slackening of the said rope will allow the said plat-form to descend by gravity.

On one end of the main drive-shaft is a sprocket wheel or pulley, B,from which a chain or belt passes to a sprocket wheel or pulley, C', on a shaft, D', journaled in the frame of the machine. The wheel O turns loosely on its shaft, and by means of a clutch, E', carries it in one direction only. One portion of the clutch is annularly grooved and is splined to the shaft to permit a longitudinal travel. A spring-arm, F', with one end resting in the said groove of the clutch, keeps it normally engaged with the pulley or wheel C', while a lever or pawl, G', pivoted in the frame and connected to a shaft, II', extending to near the drivers seat, so as to be conveniently operated by him, disengages the clutch from the pulley or wheel C', and so stops the mechanism without stopping the machine. The shaft IOO Izl' is shown in the drawings as a rock-shaft, with the upper end so formed as to engage with a catch, I', on the bridge T when the clutch E is thrown out of gear.

On the interior of the frame the shaft D' carries a bevel-gear, which operates a short shaft, K', actuating the binding mechanism.

The binding mechanism, which may be of any approved form or pattern, is not shown in the drawings, as it forms no part of the invention and would only serve to confuse.

The shaft D' carries at its inner end, beyond the inner frame beam, H, a bevel gear-wheel, L', which engages with a bevel-pinion on and gives motion to a shaft, M', journaled to the frame, and which carries a crank, N', giving a reciprocatory movement to the cutterbar by means of a pitman, O. (See Fig. 2.) The gear L' also operates a shaft, I2', which passes through the rear of the frame and there carries a sprocket-wheel or pulley, R'. From this pulley the chain or belt passes to a wheel, S', at the end of one of the platform-carrier rollers, thence upward to a wheel, T', on the reel mechanism driving-shaft U', thence downward to a wheel, V', on one of the elevator-rollers, and thence over the loose pulley W' to the said wheel R'. A cog-wheel or pinion, X', on the roller carrying the wheel V engages with a cog-wheel, Y', on another of the elevatorrollers and serves to operate the same. (See Figs. 2 and 3.) These various rollers, except those belonging to the platform-carrier, are journaled in the uprights support-ing the bridge T. The shaft U' extends longitudinally under the bridge, closeup to it, out of the way of the elevatorcarriers, and projecting beyond the nprights in which the said rollers are journaled is there provided with a gear-wheel, Z', which intermeshes with one on a short transverse shaft, A2, projecting beyond the sides of the bridge. The projecting portions of the said shaft form a pivotal bearing for the reelsupporting frame B2.

The front of the machine is supported on a casterwheel, P2, journaled to a sector-plate, R2, which in turn is pivoted at its center to a post, S2, which turns in its bearings, so as to allow a lateral movement of the wheel P2. The curved edge of the sector-plate is formed into a rack and passes through a slot in the post. A combined pinion and pulley, T2, isl

journaled in thepost above the sector-plate. In the frame-work of the machineabove the pulley T2 is a pulley, U2, on a s hort shaft carrying also a worm-gear, V2. A chain or wire rope connects the two pulleys. A shaft or rod, W2, with a handle near the drivers seat and a worm at the other end engaging with the gear V2, is journaled on the machine, and serves as a means whereby the mechanism controlling caster-wheel is operated, and the front of the machine raised or lowered at will. The mechanism above described is clearly u shown in Figs. l, 8, and 7.

By reference to`Figs. 2 and 3 it will be seen that the grain-receiving platform is hinged to the frame at X2 in the front and Y2 inthe rear. By removing the wind-board Z2 and the bolt A3 from the rear and the bolt B from the front the entire platform may be turned up so as to-rest against the bridge, the reel having been rst thrown as far to the front as possible. By this arrangement the transportation and shipment of the machine through narrow places and convenience for storing is greatly facilitated.

In the foreground of Fig. 1 is shown an auX- iliary aXle, which is designed for use when it is desirable to move the machine from place to place, and is secured to a position under the front of the main frame of the machine by a king-bolt passing through a socket, C3, on the frame and a similar socket on the said axle. The grain and caster wheels are re moved from their journals and placed on the auxiliary axle. The purpose of the axle is to provide a wide support for the front of the machine when it is transported, as the grainreceiving platform is then raised and the grainwheel would no longer partially support the machine, and the front would be supported by the caster-wheel only, and the liability of the machine tipping over greatly increased. By placing the axle as described the said grain and caster wheels are utilized and a secure support obtained. A tongue, D3, is removably secured to the frame by flexible couplings, and may also be attached to the axle when the machine is transported. As the front casterwheel sustains the front of the machine when in operation, and the tongue is flexibly connected to the frame, strain on the horses necks from the weight of the machine is obviated.

In transportation the two drive-wheels are used, while in cutting and bundling the grain one will do, and both may be used. All the grain is carried under the bridge before being delivered to the binder, and the elevation to which it is carried is comparatively small, thereby making the power necessary for the operation proportionally less.

The operation is clearly apparent from the foregoing description.

As the invention is not conned .to the specie construction nor the eXact location of the various parts as herein described, and shown in the drawings, and as it is not intended toA limit the claims by placing a too restricted interpretation upon the above specification, the right to vary the machine and its parts consistent with the spirit of the invention and its novelty is reserved.

The reel and mechanism connected there with, as shown in Fig. l of the drawings, forms no part of this invention.

I claim-' 1. In a harvester, a platform vertically adjustable on the drive wheel or wheels and on the grain-wheel simultaneously and on a front supporting wheel independently, combined with means, substantially as specified, whereby the several adjustment-s are effected, substantially as described.
