SPECIFICATION forming pm of Letters Patent No. 280,873, dated July 1o, 188e. Application tiled February 10, 1883. (No model.)

To au whom) it may concern:

Beit known that I, PRATT A. Srronn, of

Marshall, county of Calhoun, State of Michigan, have invented a new and useful Improvement-in Hay-Teddeis; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a 4part of this speciiication.

This invention relates to that' class of haytedders in which the supporting-wheels are provided with cogs that operate pinions on a shaft carrying the tedder-teeth, such` pinions being capable of adjustment toward and from the cogs for the purpose of throwing them into and out of action, thereby causingy the tedderteeth to operate or remain stationary, as occasion requires.

The object of my invention is to provide a novel construction and combination of parts, whereby the tedder-teeth can be thrown into and out of action; and the invention has other objects, which will be hereinafter explained.

In the accompanying drawings, illustrating my invention, Figure 1 is a longitudinal section of a hay-tedder embodying my invention, and Fig. 2 is a broken top plan view of the same.

Referring to the drawings, the letter A indicates the supporting-wheels; B, the main frame; C, the shaft which drives the tedderskein or journal for receiving the hub of the teeth; C', the pinions at the ends of this shaft, there being preferably one at each end of the shaft, said shaft preferably made in two parts meeting at the middle.

A- represents the annular cogged wheel,

either fastened to or made uponthe face of the wheel A, and adapted to mesh with the pinion C. The shaft C is fastened rigidly to the frame B.'

D is the axle. It is fastened rigidly to the frame by suitable attachments, D. Its ends Dt are bent into the form of a crank, so that the wheel is carried out to the side, as shown in the drawings.

E is an end lever, provided with a suitable thumb-latch, E.. This lever is rigidly keyed or otherwise secured to the shaft D, so that by forcing the lever forward or backward it will Ythe position shown in Fig. l, these centers may be caused to approach each other, and so throw the teeth out of gear and out of action.

F represents the arm which supports the tedder-teeth, which arm, at its lower end, is engaged at f to its crank upon the teddershaft, while its upper end is connected by links 'f2 to the forwardfportion of the frame.

` G is the tedder-tooth. .It is suitably secured by a clip, g, to-the upper end of the arm F.

The tooth is curved into the form substantially asishown in Fig. l, and passes loosely through is therefore no danger of deranging either the tooth itself, the arm F, or its attachment to the crank upon the shaft C. The block H is made preferably so as to provide for the adjustment up and down upon an arm, F. This is accomplished, as shown in Fig. 2, by a series of adjustingholes, It. The object of this adjustment of the block up and down the arm F is to set the tooth, so that when it strikes the ground it will strike at a point either farther forward or farther backward, as the case may be, so as readily to attach the machine for working a heavy or a light crop of hay.

I represents 4the lever, a segment, I2 the latch, and I a link connected at one end with the segment and at the other end with the frame B. This serves as a means for lifting the tooth, so as not to touch the ground when the machine is being transported from place to place.

F represents the location of the seat. The tedder-teeth are arranged in pairs in the usual manner. The arms F, it will be observed, have their lower ends terminating at the crank-shaft C, and their upper ends are connected by links with the frame, as before described. This feature of terminating the arms at the crank, instead of causing them to project well below the cranks, as is customary, is a valuable feature of my improvements, for there is less liability of fouling with hay or of striking obstructions over which the implement may be drawn.

IOC)

It will be observed that the redder-teeth are very long, and extend from the ground upward to the upper end of the supporting-arms F, and are there curved into the form of a loop. This gives a very wide range of flexibility to the tooth, and enables it not only to operate easilyJ and yieldingly, but gives it a wider range of elasticity in throwing the hay, thus causing the machine to operate more easily and steadily and without so great wear upon its working parts.

"What I claim isl. The combination, in a hay-tedder, of an axle having at each end a crank, on which cranks are mounted supporting-wheels provided with a cogged ring, a single lever rigidly fixed to the axle, a shaft having a series of cranks and a pinion at one lend tol engage and disengage the cogged ring, and tedder-teeth connected with the cranks of the shaft and having a pivotal connection by means of links with Ythe main frame of the machine, substantially as described.

2. The combination, in a hay-tedder, of the crankfshaft, the arms secured at their lower ends to the cranks of said shaft, and the tedderteeth connected with the arms at their upper ends and at points between their ends, substantially as described.

3. The combination of the axle having` a crank at each end, on which cranks are mounted supporting-wheels provided with a cogged ring, a single lever rigidly fixed to the axle, a crank-shaft in rear of the axle, having a pinion for engaging and disengaging the cogged ring, rigid arms secured at their lower ends to the cranks of the said shaft, links connecting the upper portions of the arms with the main frame, andtedder-teeth secured to` and carried bythe said rigid arms, substantially as described.

4. The combination, in a hay-tedder, of thecrank-shaft, the arms secured at their lower ends tothe cranks of the said shaft, and the tedder-teeth attached to the said arms, and having their upper ends bent into the form of a loop and secured by a clip to the upper end ofthe arms carried by the crankshaft, substantially as shown and described.

5. The combination of the rotating cranked shaft, the arms secured to the cranks of the said shaft and having their upper ends connected with the forward portion of the vmain frame, the tedder-teeth' having their upper ends secured to the top portions of the arms, and the blocks H, attached to the said arms, and having eyes through which the tedderteeth extend and are adapted to slide, substantially as and for the purpose described.

6. The combination, in a hay-tedder, of the shaft having cranks, the arms Vsecured to the cranks of said shaft and having their upper ends connected with thel mainframe, the tedder-teeth having their upper ends secured to the top portions of the arms, and the blocks H, adjustable up and down on said arms, and having eyes through which the tedder-teeth extend and are adapted to slide, and means for holding the blocks in their adjusted position, substantially as described. j n

In testimony whereof I sign this specification in the presence .of two witnesses.
