' IMPROVEMENT IN HAY-TEDDERS.

Specification forming part-of Lett'ers Patent No. 177,418; dated May 16, 1876; application filed February 1'2, 1876. r 1

To alt whom it-may concern Be it known that I, STUARrPERnY, of Newport, in the county of Herkimer, and State of New York, have invented certain new and useful Improvements in Hay-Tedders;

and I do hereby declare thefollowing to be a full, clear, and-exact description-of the inven-' tion, such as will cnable others skilled in the ar-t 'towhich it pertains to makeand use it, reference being had'to the accompany drawings, which form part of'this specification.

Figure 1 is-a perspective view-ofthemachine. Fig.2 is-a sectional viewof the same. Fig. 3-shows the through-axle and the reel-frame securedthereto. Fig. 4: represents the gearwheel and road-wheel detached, showing the means employed for effecting their attachment to each other. Fig. 5 represents an enlarged view of the reel-frame-adjusting device. Fig. 6 represents an enlarged viewof one of the'reel. gear-wheels, showing the manner of pivoting the pawl thereto, and also a spring-lever to-throwthe pawl out of mesh with the ratchet.

This invention relates to the construction and arrangement of parts in a rotary tedder; audit consists, first, in the combination, with a reel-frame constructed without a cross-bar in rear of the axle. and arranged to carry the reel between'the road-wheels, of the throughaxle and'the rocking tine-shaft, whereby the tine-shaftsareallowed to work in close proximity to the axle; secondly, in rigidly attachingthe cross-bar of-the reel-frame directly to the through-axle by axle clips, bolts, or in any suitable manner, thereby imparting strength tothe .axle without recourse to a separate wood backing, as has heretofore been employedin this connection; thirdly, inthe combination, with a reel-frame rigidly secured to a through-axle, ofa draftframe hinged to to the front portion of the reel-frame, for the purpose of wholly or partly counterbalancing the weight of'the reel-frame by the weight of the driver on the draft-frame; fourthly, in the frame and reel-frame, of a hand-lever, serrated or notched bar, lock-bar, and an adjustable spring-actuated pawl, the several parts being arranged and-combined in such a mannerthat the spring always exerts a constant pressure between the draft andreel-frame; sixthly, in

the combination, with a pawl engaging with the ratchet within the face of the gear-wheel,

of a spring-lever arranged relatively to said a are placed journal-bearingsa a, to the ends ofwhich the arms 0 O of the reel-frame are rigidly secured. The arms 0 G are crossbraced by the cross-braces D D, the former serving as a support for the draft-frame E, while'the cross-bar D rests upon the axle B, and is rigidly secured thereto by means of axle-clips, bolts, or inany other suitable manner.

The cross-bar D, arranged in direct contact with the axle, will admit of an'easy adjustment of the reel-frame, the axle serving as the pivotal bearing upon which the reel-frame oscillates, and also the cross bar serves as a backing to materially stiffen and strengthen the through-axle B; Heretofore the reelframe has been constructed with a cross-bar in rear of the axle, thereby removing the reel-journals the breadth'of' the cross-bar from the axle or vpivotalbearing of the reel-frame My improved arrangement and constructionof reelframe con sistin securing the cross -bar directly upon top of the through-axle, whereby'the tines may swing in close proximity to the axle.

Theleverage of the reel-frame is thus shortened,

the draft is more direct, and the reel-frame can be readily adjusted by the operator.

The driving gears F F are constructed with horns or lugs b, preferably of a number to correspond with the spokes of the road-wheel,

and each of said horns has an offset or pro jection that enters the felly of the wheel.

Through holes b in horns b, are inserted bolts b, which firmly unite the driving-gear to the road-wheels, and effectually prevent their slipping on each other. T6 the arm 0 of the reel-frame the camway G is attached.

The tine-shafts H H have imparted to them a variable movement through the medium of the arms-c c which are fastened to the ends I cesses f in the gear-wheels, and springs g serve to keep the pawls in contact with the ratchet.

During the forward movement of the tedder the gear-wheels I I are locked to the reel-shaft by means of the pawl and ratchetabove described, and the reel is positively rotated thereby, while in the backward movement of the machine the pawls are free to slip over theteeth of the ratchets, and the reel is not affected by the movement of the machine.

In order to completely isolate the pawl from the ratchet at will, that the reel shall not be actuated either during the forward or baclc.

ward movement of the tedder, spring-levers are combined with the pawls, as follows:

Spring-levers J are pivoted to the rims of gear-wheels I I. at j, the handle or long end of saidlever, when not employed, resting between pins k, the other end of the lever serving as a guard-plate to retain the pawl in place.

When it is desired to throw the pawlout of contact withthe ratchet, the handle of the spring-lever is raised above the top of the inner locking-pin 7c, and moved over. the same so that the outer edge of the lever rests'against theinnersideofthepin. Thismovementthrows out the other end of thelever, which catches on a projection, 1, formed on the side of the pawl, and thus removes the working face of the pawl clear of the ratchet. In order that the weight of the driver may serve to wholly or partially counterbalance the weight of the reel and its frame, the draft-frame E (to which the drivers seat is secured) is hinged to the cross-bar D of the reel-frame, said cross-bar being situated in front of the axle B.

K is a notched or serrated sector-bar, which is hinged in front of the draft-frame E, while its free end is arranged to slide within an opening in the hand-lever M, a pin, 1, through the end of the sector-bar, preventing the acciilental detachment of n the bar from the band ever. i

The hand-lever M is firmly secured between the cross-bars D D, and projects upward within easy reach of the driver. 0 is a lock-bar, and is pivoted to the hand-lever at M. A groove, 11., is formed in the face of the lockbar, and within said groove rests the end of retained therein by the tension of the spring P. The lock-bar 0, being forced against the hand-lever, lifts the pawl from its notch, and retains it in groove 01. of the lock-bar, when the lever carryingthe pawl and spring may i be moved along the sector-until the desired adjustment is effected, and then by releasing.

the lock-bar the pawl instantly engagesin a notch in the sector. l

The devices above described for insuring; a constant and eqnable pressure on the reel,at variable adjustments, constitute and import-Q tant feature of my invention,forthe following reasons: The height of the thillsorpole above .I. -the ground will, in practice, vary to a considerable extent, on account, of diiferentheightsu of horses, construction of harnesses, theirregui larity of the surface of the field,owin g to knolls,

ridges, and other obstacles met with, requir-;

ing different degrees of adjustment of thereel.

to conform to the height of theathills or pole, 1

and as it is desirable that a constant or;equa-.

ble pressure should beakepton the reel atiall times, it is of great importance that the spring.

by means of which the saidlpressure is accom-L plished should form a part of: the adjusting.
