IMPROVEMENT lnv HAY-SPREADERS.

HMV

The Schedule referred to in these Letters `Patent and making p art of the same.

To all whom fit mm1/concern: v

Be it known that I, M. D. MYERS, of Frankfort, in the county of Herkimer, ,and State vof New York, have invented a new and improved Hay-Tedder; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being Similar letters of reference indicate corresponding parts. A

This invention relates to an improvement inhaytedding machines; and

It consists in the construction and arrangement of the endless chainsthe stationary drums, and the drums axed to the shafts'calrying the tines for spreading the hay, as will be hereinafter more fullyA described.

A, in the drawing, represents the wooden or other `frame of my improved hay-tedder. The said frame is' of suitable shape, construction, and dimensions. In it are the bearings of the rotating drivin gwheel axle, B, on which the wheels, C and D, areA respectively hung,- as shown.

The wheels are connected with ,the shaft B by; means of ratchet-wheel a and pawl b, so 'as to revolve the shaft when the machine is drawn forward, but to leave it at'rest when backing up.

By means of suitable gear-wheels, c (l e, or equivaf lent mechanism, the driving-shaft B, or, if desired, one of the driving-wheels C D, is connected with a horif zontal shaft, E, which has its bearings in the rear part of the frame A, and which is parallel with vthe shaft or main axle B, as shown. When the machine is drawn forward, the sh-aft E turns in the same direction as the driving-wheels.

On the shaft E are mounted four or more, o1` less, projecting arms, F F, each arm projecting with both Aends an equal distance from the shaft, as shown When four arms are used, as in the drawing, the shaft Eis supported in thel middle and at the ends, and there istherefore, an arm, F, at each end ofthe shaft, and o 4e 4on each side of the central support, f, as shown.

The ends of each pair of arms, on each side of the support f, are connected, by means of horizontal shafts G G, which have their bearings in the arms, and can turn loose therein.

rom the shafts G project the tines H H.

0n one end 'of each shaft G is mounted a pulley, g,`

and, in line with each, such pulley is fitted to the frame A, concentrically around the shaft E, a fixed disk or drum, h.

An endless-chain, belt, or band, z', connects each wheel y withits disk It, as shown. v

As the 'shaft E isrevolved, the tine-shafts G will also be turned, or, rather, swung around the axis of the said shaft E, and they would, during each revolution of the shaft E, make also one revolution around 'their own axis; but this rotary motion around `their own axis is prevented by the chain or band t', whichkeeps'them back, so as to keepthem from turning at allaround their own axis, and'to thus keep the tines always in the same relative position tothe ground, which position is' nearly perpendicular. f

As the machine is drawn ahead, the tines are carried around the shaft E-without being turned, and` enter the hay in the without taking it up.

Although the shafts G thus appear to be at rest,

proper position for turning it they do actually turn in their beaiings,.or, rather, the

bearings turnaround them.

In connection with the above-described apparatus, tines., of suitable construction, and attached in suital ble manner, may be used, and I do not confine the uses of the said working-mechanism to any particular style of tines.

The tines H H are made in pairs, of suitable wire. This wire is coiled around the shaft` G, on each' side of a sleeve, I, which is adjustable on the shaft, as shown, and the wire is also tted intoa notch formed on the said sleeve,v as shown in gs. 2 and 5. f

The sleeve I is adjustable on the shaft G, and can be fastened in any suitable position, by means of a setscrew, j, as shown. l

It has a projection, It', which is grooved, as shown, to admit the wire.

The wire is coiled around G, on eitherside of the sleeve, as in ig. 5, audits ends form the tines, which are, bythis arrangement, made reliable, strong, and elastic.

Having thus described my invention, Y

v What I claim as new, and desire to secure by Letters Patent, is

The construction of the endless chains t and the drums h g, and their arrangement with relation to each other, the horizontal shaft E, tine-shafts G, arms f, and frame, as herein described, vfor the purpose specified.
