HAY-TEDDER.

SPECIFICATION forming part of Letters Patent No. 393,115, dated November 20, 1888.

Application tiled November 7, 1887. Serial No. 254,498. (No model.)

.T0 all wtom it may concern:

Beit known that I, PETER E. LiTTLE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Hay-Tedders, of which the following is a full, clear, and exact descripltion, reference being had to the accompanying. drawings, forming part of this specification.

My invention relates to that class of haytedders known as revolving tedders, in which the tedding-teeth are secured to a shaft revolved by the forward motion ofthe machine; and it has for its object the improve` nient of this class of machines, by which their construction is simplified and their efficiency increased.

The novelty of my invention will be herein set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is a plan View of a tedder embodying my invention with a portion of the stripperbar broken away. Fig. 2, Sheet 2, is an enlarged perspective of one of the tooth-holders. Fig. 3, Sheet 2, is a side elevation of the niachine. Fig. 4, Sheet 2, is a sectional side elevation through the dotted line x x of Fig. l.

i The same letters of reference are used to indicate identical parts in all the figures.

The main frame of the machine, supported and hung on the axle, may be of the usual or any suitable construction. In this instance it is composed of the side bars, A, forward crossbars, B, and center bar, C, secured to the crossbars. The carrying-Wheels D are journaled upon the axle E, which in turn is suitably journaled in boxes F, secured to the bars A. The tedding shaft G is journaled in boxes H upon the rear ends of the bars A, and just outside of said bars isprovided with -sprocketwheels I, suitably keyed or secured thereto. Drive-cliains J connect the sprocket-wheels I with other sprocket-wheels, K, secured to the axle E between the bars A and the carryingwheels D.

The thill-fraine is composed of the thills L, pivoted at their rear ends to the bars A, as at a, and the cross-bars M, to which the seat-beam N, carrying the seat O, is secured in the usual or any suitable manner.

To enable the main frame to be tilted to adjust the height of the tedding-teeth from the ground for various kinds or conditions of work, and to lock the main frame (when adjusted) and the thill-frame together, I employ' a bell-crank locking hand-lever, I), which is pivoted to asegment-rack, Q, supported upon and secured to the crossbars M. A pivoted link, R, connects the forward end of the bell- 6o handle c, for holding the lever P locked to the rack Q in any of its adjusted positions.

The wheels D may have the usual ratchetand-pawl connect-ion with the axle E, so that in backing the machine the axle, and consequently the tedding shaft and teeth, will not 7o be revolved; or, if desired, the ratchet-andpawl connection may be between the sprocket-wheels I and the tedding-shaft, to prevent the action of the tedding mechanism When the machine is backed, as will be readily understood.

The tedding-teeth S are of the general shape and construction of rake-teeth, except that their outer or Working ends, instead of curving forward like rake-teeth, are given areverse 83 or backward curve in the direction of their revolution, as shown. This is an important feature of my invention, for by thus shaping the teeth the tedding action is rendered more perfect, and the liability of the hay being car- 85 ried up on the teeth is lessened. Y

The teeth are secured to the shaft Gin sets, each set composed of two pairs, in the following manner: For every set o f teeth there is a tooth-holder, T, Fig. 2, consisting of a sleeve 9o provided with tangential projections d, extending therefrom at points diametrically opposite, and provided on each side with outwardlydiverging gutters to receive the ends of each pair of teeth, which are bent to conform to the shape of the gutters and are held securely by clips @,bolted to the holder, one of said clips on each side embracing the inner ends of the teeth and the other embracing the teeth at a point Where they leave the holder.' The holders, 10o

with the teeth attached, are strung upon the shaft G, and after being properly spaced and adjusted are secured thereto by any suitable means. It will be seen that the teeth lie in the grooves in the tooth-holders and are se curely clamped at two points, all twisting or lateral motion being prevented by the bends in the teeth between the two clips, located, as before stated, one on cach of the tangential projections. It will also be observed that the teeth of each pair diverge from each other, for a purpose to be presently explained. I prefer that the adjustment of the teeth be such as to bring the sets spirally upon the shaft, as illus trated in the drawings, thereby lightening the dra-ft of the machine when working.

'Io prevent the possibility of the grass or hay adhering to the teeth, I provide stripper-teeth U, which are secured at their upper ends to a bar, V, which is supported upon the ends of inclined rails W, secured at their forward ends to the bars A of the main frame. The stripper-teeth are arranged in pairs coincident with the sets of tedding-teeth, and the teeth of cach pair diverge from each other and are curved forward at their lower ends in such manner that in the revolution of the tedding-teeth each pair as it ascends enters at the narrow or converging base between the separated ends of the co-operating pair of stripping-teeth, and as the teeth continue to revolve they bear against the stripping-teeth throughout their entire length and effectually scrape off and remove any adhering material. It is obvious that this result would be accomplished were either the tedder-teeth or the stripper-teeth alone diverging. Forinstance, were the stripper-teeth straight and the tedder-teeth d iverging, they would enter between the stripper teeth at or near their bases, where they are close together; and, on the other hand, were the tedder-teeth straight and the stripperteeth diverging, the ends of the latter would be separated wide enough to pass outside the tcdder-teeth, as will be readily understood.`

By this arrangement it is only necessary to employ one pair of stripper-teeth to two pairs ol" tedding-tecth, as the pairs on opposite sides of the shaft rotate in the same plane.

From the above description it will vbe seen that I have produced a tcdder of cheap and highly-efficient form, which by reason of the pairs of diverging teeth will cover a large surface, while affording the most secure and least number ol' fastenings for the teeth, and at the same time eft'ectnally preventing the retention of any hay or other material on the teeth.

Having thus fully described my invention, I claim- 1. In a hay-teddcr, the combination, with the tedding-shaft, ofthe tooth-holders carried thereby, having the tangential projections oni opposite sides, with the diverging grooves therein for the ends of the teeth, and clamps for holding the teeth in position, substantially as described.

2. In a hay-tedder, the combination, with the tedding-teeth arranged in pairs on a revolving tedding-shaft, the teeth of each pair diverging from each other, of coincident pairs of diverging stripper-teeth, the ends of which pass outside the tedding-teeth at their bases, or at a point Where said teddingteeth are near together, substantially as described.

3. Ina hay-tedder, the combination, with the tedding-teeth arranged in pairs, the teeth of each pair diverging from each other, of

tooth-holders mounted on a rotating tedding- 4 shaft, each holding two pairs of tedding-teeth, one on each side of the shaft, and coincident pairs of diverging stripper-teeth, the ends of which pass outside the teddingteeth at their bases, or at a point where they are close together, and each -pair of which engages two pair of oppositely-arranged tedding-teetlnsubstantially as described.

1I. In a hay-tedder, the combination, with the shaft, of a tooth-holder formed with the sleeve encircling the shaft, and with the oppositely arranged tangential projections grooved on both sides, and clamps or lockingclips for holding the teeth on each side of said projections, substantially as described.
