JEREMIAII. KELLER, OF SANDUSKY, OHIO, ASSIGNOR TO XVALDO F. CONVERSE, OF SAME PLACE.

HAY-'Tenore SPECIFICATION forming part of Letters Patent No. 311,991, dated February 10, 1885.

i Application filed February 23, 1884.

To @ZZ whom, it may concern.-

Be it known that I, J EREMIAH KELLER, of Sandusky, in the county of Erie and State of Ohio, have invented new and useful Improvements in Hay-Tedders; and I do hereby de`- clare that the following is a full, clear, and eX- act description thereof, reference being had to the accompanying drawings, which forma part of this specification.

This invention relates to certain new and useful improvements in the construction of hay-tedders; and the invention consists in the peculiar construction of the forks and means employed for operating them, and in the pe- I culiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.

Figure l is atop plan. vation. Fig. 3 is a rear elevation, partially in section. Fig. ft is a detached perspective view of one-of the rotating heads and its actuating mechanisn'l. Fig. is a section through x 0c of Fig.

In the accompanying drawings, which form a part of this specification, A A represent the two traction-wheels, which are mounted upon the axlearms B, the inner ends of which are journaled in the upper ends of the brackets C, which are in turn rigidly secured 4to the central bar, D.

F F represent two shafts, upon each of which is rigidly secured a circular head, a, near the inner ends ofthe shafts, while near their outer ends are rigidly secured the heads b, the outer ends of the shafts being journaled in the outer ends, c, of the brackets O, while their inner ends are journaled in a box, G, on the outer end of the central bracket, H. Upon the outer ends of the shafts F there are secured sprocketwheels I I, which impart motion to the shafts through the medium of chains J .I from large sprocket-wheels K, sleeved upon the axles B. Said wheels Ii are provided with a spring-dog, d, which engages with a ratchet, c, upon thel inner ends of the hubs of the wheels A, the whole being so connected that in the forward motion of the machine a rotary motion is imparted to the shafts F. Between cach pair of heads a b of these shafts F are properly journaled' the three rock-shafts L, upon each of- Fig. 2 is a side ele- (No model.)

which is secured a pair of spring tedder teeth or forks, M. The outer ends of these rockshafts pass through the heads b, and have rigidly secured to them crank-arms h, carrying anti-friction rollers i, which travel in the grooved cams j, formed in the inner faces of the heads c of the bracket-s O.

Rising from the bar D is a standard, N, which carries a spring-latch, O, adapted to engage with a curved rack-bar, I), upon the draft-frame. By these means the device can readily be partially turned upon the axles B, so as to vregulate the height of the tedder-forks from the ground.

As the device is drawn forward a rotary motion is imparted to the shafts F through the connection herein named, an d a partial rotary movement is likewise given to the shafts which carry the tedder-forks, causing them to thoroughly perform the functions for which they are designed.

I am aware that it is not new to provide haytedders with a single rotating shaft extending the full width of the machine, said shaft carrying a single tedder-reel, and do not broadly claim such as my invention, for in such construction, when the machine is .turning a corner or traveling in a curved line, the tedderreel has the same motion throughout its entire length, which is objectionable, and not absolutely necessary, as that part of the machine on the inner track has a less distance to traverse, and consequently there is no necessity for that part of the tedder-reei on the inner side of the curve to travel as fast as that part on the outer side. By my construction the reelshaft and redder-reels are `each in length only about half the width of the ma chine, but together occupy a space equal to the width of the machine, and as each reelshaft is independently driven from the traction-wheels an unequal motion is given to each tedder-reel in passingaround curves in proportion to the radii of said curves, thus economizing powcrand diminishing the wear of the machine.

'What I claim as my invention is- 1. In a hay-tedder, the brackets C, attached to the draft-frame D, each having bearings for a short independent axle-arm, I3, at its upper IOO YIO

end, and each provided with a cani-grooved head, c, at its other end, in combination with the independently-rotating shafts F, j ournaled between said heads, and means whereby an independent motion is imparted to each shaft, substantially as and for the purpose specified.

2. In a hay-tedder, the brackets G, secured to draft-fra1ne D at one end, in combination with the bracket H, attached to the draftfrarne, and provided with a bearing, G, shafts F, independently j ournaled between said brackets, one on either side of the bracket H,

' andv carrying the rock-shafts L, and means for independently rocking the shafts L, as and for the purposes setforth. i

3. In a hay-tedder, the brackets C, secured to the draft-frame at one end, and provided Titnessesz N. T. CURRAN, J. B. DAVIEs.
