HENRY HITCHCOCK, O F LYONS,v MICHIGAN.

HAY-TEDDER.

SPECIFICATION forming part of Letters Patent No. 239,250, dated March 22, 1881,

(No model.)

' To all whom t may concern Be it known that I, HENRY HITCHCOCK, of Lyons, in the county of Ionia and State of Michigan, have invented an Improvement in Hay-Tedders, of which the following is a specication.

The nature of this invention relates to certain new and useful improvements in the construction of hay-tedders, which will be effective in operation, simple in construction, easily controllable, and wherein the tedder head or shaft, with its accompanying teeth, may be removed and a seeding-machine substituted therefor, the operating mechanism being adapted to drive other machines equally as well as the tedder-head.

The invention consists in the peculiarities in the details of construction and the various combinations and operation of such details, as more fully hereinafter described.

Figure lis a longitudinal section on the line x x in Fig. 2. Fig. 2 is a plan, showing one side of the machine, both sides being alike. Fig. 3 is a cross-section through the tedderhead. Fig. 4 is a detached and perspective view of one of the teeth.

y In the accompanying drawings, which form a part of this specification, A is aframe, which carries the operating parts of the machine. This frame is pivotally secured by eyebolts a, or other equivalent devices, to the frame B, to the rear end of which the axle C is rigidly secured. The former frame rests prone upon the latter, and extends to the rear, as shown in Fig. l. y

D are the traction-wheels, journaled in any of the known ways to the axle, at each end thereof.

E are sprocket-wheels, secured and adapted to rotate with the traction-wheels. Sprocketchains F convey motion from these sprocketin Fig.1. `The`teddershaft J is provided with curved spring-teeth L, secured thereto in'any convenient or desired manner in pairs, one projecting each way from the shaft, and theseries of pairs so. arranged that when all are in place they run spirally around the shaft.

M is a caster-wheel swiveled to the curved standard N, which passes forward over the axle C and beneath the frame A, and its forward end is pivoted to the under side of said frame.

C is a cani-lever, pivoted within the slot b in the frame A, and projecting through the same,

`to engage with the horizontal part of the standard N. By drawing this lever to the rear the cam raises the frarne A, and of course the tedder, and thereby the operator is enabled to raise or lower the tedder-shaft at will.

The caster-wheel also serves to keep the device level and steady when one of the tractionwheels may be ruiming in a dead-furrow.

The boxes K, which carry the tedder-shaft, are arranged to slide on the frame A, forward or back, just sufficiently to engage and disengage the pinion I with the internal teeth of the sprocket-wheel Cr, and suitable connections are made, so that the driver on his seat may control such engagement or disengagement.

Heretofore a 'tedder-shaft journaled in boxes sliding in aframe has been revolved by means of a belt passing around a pulley secured to the driving-wheel, and thence around a pulley on the endof the tedder-shaft, the latter being caused to revolve or not by sliding' the boxes to and fro on the frame, thus tightening or slackening the belt to cause the tedder-shaft to revolve or not, as desired; but in this construction when the belt is slackened a part of its weight rests on the tedder-shaft, and is liable to operate it to some extent, and besides the belt is liable to fall oft' the shaft in its slackened position. In my construction the belt or sprocket-chain is never slackened, and no such results occur. The internally-geared sprocket-wheel is driven always by a tightened sprocket-chain, and the tedder-shaft, when revolved, is operated always by the positive action of the pinion and internally-geared sprocketwheel. When the tedder-shaft boxes are slid inwardly, and the pinion and internally-geared wheel are thrown out of gear, the connection IOO between the driving mechanism and teddershaft is entirely severed, and the rotation of the redder-shaft is at once stopped.

In practice the tedder-shaft may be removed and replaced by the shaft of a seeder or other device Where a like motion is required and adapted to be driven by the mechanism herein described.

What I claim as my invention is 1. The combination, with the frame A and traction-wheels I), of the sprocket-Wheels E, secured to and adapted to rotate with the traction-Wheels, sprocket-chains F, internallygeared sprocket-wheels G, sliding,` boxes K, and tedder-shaft J, having the pinions I secured to its ends, substantially as described, and for the purpose set forth.
