COMBINED HAY TEDDE R AND RA KE.

SPE CIFICATION forming part of Letters Patent No. 290,775, dated December 25, 1883, I Application filed February 12, 1883. (X0 model.)

To-alZ whom it may concern.-

Be it known that I, WILL R. JOHNS, a citizen of the United States, residing in the city of Rockford,- in the county of Winnebago and State of Illinois, haveinvented new and useful Improvement in a Combined Hay Tedder and Bake, of which the following. is a specification.

This invention relates to that class of tedders and rakes in which the tedder apparatus may be disconnected from the main frame, which is mounted on the carrying-wheels, and the rake-head connected thereto, or vice versa, and. in which the tedder-teeth rotate.

The object of this invention is to improve this class of combined machines, to render them more efficient and reduce rather than increase their cost. To this end I have designed and constructed the machine represented in the atc Jmpanying drawings, in which Figure 1 is a side elevation of a machine embodying my invention, and in which one of the carrying-wheels with the cog-toothed rim fixed thereto is omitted. Fig. 2 .is a rear elevation; Fig. 3 is a rear elevation of the end portion of-the tedder-shaft and clutching mechanism, partly in section. Fig. 4 is an isometrical representation of the tedder-tooth hub and portions of the tedder-teeth in place therein. Fig. 5 is an isometrical representation of a portion of the rake-head, with a portion of some of the rake-teeth.

f In the figures, A represents carrying-wheels mounted to revolve on the axle-arms of the axle-tree B.

AtC are represented thills of a suitable construction, and are hinge-jointed to the axle B in a manner to permit the axle-tree to oscillate in its wheel-supports.

At D is represented a drivers seat fixed to the upper end of an inclined support, E, having its lower end fixed to the transverse bars of the thills in such a manner 'as to support the seat suitably elevated centrally over the axle-tree.

At this represented a segment-toothed ratchet fixed to the transverse bar of the thills.

At b is represented alifting and holding lever pivoted on the center of the segmentratchet.

This lever is fitted with a thumblever, c, to operate a detent-boltto engage the teeth of thesegment-ratchet.

At 11 is represented a link having a pivotal connection with the lever b, and with a vertical arm, 0, rising from the axle-tree.

It will be seen from the foregoing that the construction and arrangement of these several parts are such that a forward and backward movement of the lever will cause the axle-tree to oscillate in its wheel-supports, and that by means of the bolt-detent engaging the teeth of the segment-ratchet the axle-tree may be held inany position within the limits of the devices.

At F are represented shaft-supporting bracket-arms, having their upper ends fixed to the rear face and end portionsof the axle-tree by means of suitable screw-bolts, f, passedthrough the parts. I

.At G is represented a shaft, of suitable dimensions, journaled to revoke in the outer end portions of the bracketarms.

At 9 are represented gear-toothed pinions, loosely mounted on the outer end portions of the shaft, and are capable of a limited endwise-sliding movement thereon. The outer center of these pinions are countersunk, and the bottoms of these, countersinks are produced in a sawtooth-clutch form.

At h are represented saw-toothed clutchheads, of a form and size to enter the countersink in the gear-pinions, and engage the sawtooth-clutch-formed portion thereof. These clutch-heads are fixed on the outer ends of the Shaft;

- At t are represented lever-springs, pivoted at k to the bracket-arms, in such a manner that their free end can be raised to permit the gear-pinion to slide under it on the shaft- The position and the spring-action of these springlevers are such that their free ends shall engage the inner face of the gear-toothed pinions and hold them in contact with the clutchheads, to cause the shaft to revolve in the forward movement of the machine, and in the backward movement of the machine will per- IOO with the shaft-supporting brackets their free" a manner to cause them to revolve with the movements of the machine.

At I is represented a hub, bored to receive the shaft G, and fitted with a set-screw, Z, by which to fix it to the shaft. These hubs are provided with ears m, radiating fromone endportion of their periphery. These ears arebored parallel with the axial center of the hub, to receive the hook-end portion of the tedder-tooth. The opposite end of thesehubs, from which the bored ears on rise, are provided with catch or hook ears n, projecting from its periphery radially between the bored ears m.

At 0 are represented portions of the tedderteeth, one end of which is bent about at a right angle with the main portion of the tooth. This bent arm of the tooth is inserted in the hole formed in the arms m, and the tooth is then forced into the catch-hook on the armsn, in which position it will be securely held. These tedder-teeth 0 are produced in reverse curves of a proper form to engage the hay in their revolutions and deliver it rearward. These hubs, provided with their teeth, are placed upon the shaft G, at proper intervals, and are fixed in position thereon by means of the set-screw.

At K is represented a transverse bar, fixed at its ends to the shaft-supporting brackets.

At 1) are represented the side bars of a slotted shield or guard, having their end portion fixed to the transverse bar K, in such position thereon that the arms 1) of the guards will extend one'on each side of'each' set of' tedder-teeth, and under their shaft-support. The outer curved portion, 8, of these slotted guards is produced from wire or round bar material, bent in proper loop form to span the tedder-teeth and engage the rear ends of the bars 0, to which they are securely fixed. The rear portion of these wire-loop portions is curved upward, as shown, in such a manner as to discharge the hay lifted or thrown by the tedder-teeth in't-heir revolutions rearward, which action will prevent clogging the machine. In this instance these slotted guards are produced from two pieces; but they may readily be produced from a single piece, and,

if desired, they may be supported by suitable bearings depending from the shaft carrying the tedder-teeth.

At-L is represented a portion of a rake-head produced from a suitable beam rectangular in section, having its ends fitted with holes at t, designed to receive the bolts f, to connect it with the axle-tree B when the tedder is disconnected and removed from the carriage. This rake-head is provided, at proper intervals, with rake-teeth u, of ordinary construction, fixed to the rake-head in any proper manner, preferably in the manner shown, in which the upper edge of the head is notched, to receive the coil of the tooth, to give firni ness to the tooth when its shank is fixed in the head.

From the construction and arrangement of the machine it will be seen that a movement of the lifting and holding lever in either direction will operate to change the position of the tedder or rake teeth when the machine is employed in either capacity, which places them under the control of the driver, to hold or carry them in any position or at any elevation within the limits of the devices.

I claim as my invention 1. The herein-described tedder-tooth hub, provided with radial ears fitted to receive the bent shank ends of the tedder-teeth, and catch-ears to engage and hold the teeth, in combination, with the teeth bent to enter the perforated ears and engage the catch-ears, substantially in the manner, and for the purpose set forth.

2. The combination, with the rotary tedder teeth, of the slotted guards supported under the gear-rim, a clutching mechanism of the shaft and pinion, and a pivoted lever-spring detent to engage the opposite sides of the pinion, asand for the purpose set forth.
