HAY-TEDDER.

SPECIFICATION forming part of Letters Patent No. '7' 20,098, dated February 10, 1903.

I Application 'filed December 21,1901. Serial No. 86,832.l (No model.)

To @ZZ whom, t Wawy concern:

Be it known that I, SAMUEL BRAssrNGroN BAMFORD, a subject of the King of Great Britain, residing at Leighton Iron Works, Uttoxeter, in the county of Stafford, England,

'have invented new and useful Improvements in Hay-Tedders, of which the following is a specification.

My invention relates to machines for turning hay, clover, corn, or similar crops when lying in swaths or otherwise and comprises the improvements hereinafter described.

In the accompanying drawings, Figure l is a sectional side elevation of a crop-turning machine made according to the invention and shown adapted to turn two swaths. Fig. 2 is a rear elevation of one half of the machine, parts being removed for clearness and their location indicated by dotted lines. Fig. 2a is a rear elevation, similar to Fig. 2, of the other half of the machine. Fig. 3 is a side elevation of one of the tine-Wheels. Fig. l is a sectional viewillustrating a modication of tine. Fig. 4 is an enlarged view of a portion of Fig. 4. Fig. 5 is a top plan view of one half of the machine. Fig. 6 is a top plan view of the other half of the machine, parts being shown in section. illustrating the connection between the two rotary tine-carrying bosses carried by the inclined axles. Fig. Sis a detail view of the adjustable connection between the brackets carrying the inclined axles. Fig. 9 is a detail of a slight modification of the adjusting device for the caster-wheels. Fig. 10 is a detail of a part of the mechanism.

a is the main axle of the machine, which is mounted in the carriage b and carries the two wheels c c. Upon this axle a. are mounted two bevel-wheels d d, which gear with bevelpinions e e, mounted upon hollow shafts e e', placed at a suitable distance apart, such as that shown in the drawings, and at an angle ofjabout sixty degrees with the main axle a. To the said hollow shafts c' e' on the ends opposite those on which the bevel-pinions e e are fixed there are attached bosses or naves ff, (see Fig. 3,) having a number of tinesff', the said tines being made to spring and being arranged radially to the bosses f f, as shown` in Figs. l, 2, and 3, or approximately tangentially to the circle of revolution of the Fig. 7 is a diagrammatic viewV kcannot be withdrawn.

bosses to which they are attached, as shown in Fig. 4, and being adapted to act upon the crop to be turned and leave it lightly in rows, at the same time sweeping the ground clean between the rows. The hollow shafts e e revolve on axles e2 e2, held in brackets e3 e3, pivotally mounted upon the main axle d, so that the hollow shafts e' e can rise and fall with the contour of the ground over which the wheels c c pass. The axles e2 e2, on which the hollow shafts e revolve, are made adjustable to suit the Width of the swath and are supported at their outer ends by brackets g g, carrying trailing or caster wheels g' g', the standards g2 of which are held in sockets g3 g3 in the said brackets g g and are provided with means by which they can be raised or lowered to the requisite height with the tines to turn over the crop. In the drawings the means shown comprise a slotted lug h upon the socket g3, provided with holes h' h' and with the slot of which there engages a bar "h2, pivoted to a collar h3, loose upon the upper part of the standard g2 of the caster-wheel and having holes h4, which can be brought into coincidence with the holes h' in the lug and be secured by a pin t, passing through the holes in thelug and bar. To prevent the pin 1l pulling out, I make each hole with a slot h5 on the lower part and the pin with a small projecting nib i2 to it the slot. Thus when the pin is passed through the holes it can be turned until the projecting nib is clear of the slot, so that the pin is locked and To retain it in this position, I crank the head of the pin downward, as shown at c", Figs. 2 and 6. A chain i3 can be attached to the cranked end c", the weight of which chain keeps the crank in the downward position. When the pin is required to be withdrawn, the cranked end of the pin is lifted upward until the projecting nib on the pin coincides with the slots upon which the pin can be withdrawn and inserted in another set of holes.

Sometimes I pivotally connect a rectangular loop h7 to the loose collar h6 on the casterwheel standard, and on the bracket g4, carrying the caster-wheel standard, I make a series of projections or hooks hs, pointing downward and placed one over the other vertically, as shown in Fig. 9. To raise or lower the tines, the lower end of the rectangular loop is in ICO serted in one of the projecting hooks,'accord ing to the height required. In this way the height of the revolving tines from the ground can be adjusted. Where spring-titres ff' are employed, I preferably make each with a coil or loop at the inner end-that is to say, the ends nearest the bosses ff-thusincreasingtheirelasticity. Thisarrangementisillustrated clearlyin Fig. 3. In lieu of the springtines ff' I can use spokes f3f3, having the jointed Lines f7f7 attached near their outer ends, as clearly shown in Fig. 4. Each of these jointed tines is provided with a spring f4 at the joint to allow the ends of the tines to give way when touching the ground and afterward return to their original positions. Such construction is illustrated on a large scale in Fig. 4, in which the spoke f3 is screwed into the boss flo, the latter being bored out to receive a spiral spring f4. The tine is pivoted to the boss and is provided with a lugf11 to engage a plungerfw, inserted in the boss and working therein against one end of the spring f4. The tine is provided adjacent to its pivotal connection with the boss with a lug fm to limit the movement of the tine under the iniiuence of the spring. WVhatever the construction of the tines, however, I curve them near the ends, as shown atf5fs, so that they do not strike the ground abruptly when rotating in the direction of the arrow, Fig. 3. The extreme end of each tine is also turned back, as clearly shown in Figs. 3 and4 at f f, in order that they may pick up or turn over the crop without sliding over it.

The above description has referred to a single tine-wheel mounted upon each axle; but in order that a broad space of ground can be cleared without the tines pressing unduly upon it I can make use of two tine-wheels upon each of the axles e2, and this arrange' ment is illustrated in thedrawings. The second tine-wheelj on each axle is mounted upon the cranked end j' of this axle, the cranked portion being parallel with the main portion. The cranks are made of such a length as to keep the tine-wheelsfandj the rightdistance apart to sweep the ground the proper width required. In order that the second tinewheel of each pair of wheels may be rotated, the said two wheels are coupled together by means of connecting-rods 7c 71:, which are pivotally attached equidistantly around the circumference of a circle (see Fig. 7) to the bosses or spokes of each of the tine-wheels, the said rods acting similarly to the connecting-rods on locomotive road-vehicles. With this arrangement one wheel drives the other without the use of chains or gear-wheels.

For the purpose of throwing the machine in or out of gear I pivot a lever Z at t to a bracket m on one side of the main frame above the axle, a quadrant-plate and catch n being provided in connection with the lever. The upper portion of the lever Z can be moved and the lever fixed by the catch in the notches of the quadrant-plate in the usual manner by the driver from his seat on the machine. The lower or short end of the lever below the fulcrum Z has a forked end Z2, and the two brackets e3 e3 are connected by the bar p, adapted to be reciprocated by the forked lever and which engages a stud on the sliding bracket adjacent to it. Thus when the handlever Z is moved motion is also communicated to the two brackets e3, carrying the bevel pinions e e, which are moved along the main axle in or out'of gear with the bevel-wheels d (l. In order to adj ust the distance between the second-motion hollow shafts e', I make the harp with a series of holes p p', (shown in Fig. 8,) with any one of which the bracket e3 at this end can be engaged. The bevel or crown wheel d at this end is also made adjustable on the main axle as well as the pinion. To this end it is fixed on the main axle by a set-screw d2 in the boss of the wheel. This set-screw presses on a loose feather-key d in a sunk keywayon the main axle. When the set-screw is loosened, the wheel is free to slide on the main axle, as shown in Fig. 10, together with the feather-key, and can be fixed where required. Both the second-motion shafts in their new position can be thrown in or out of gear by means of the hand-lever and connecting-bar, as before.

q q are guards for keeping the rows of hay or the like separate from one another.

Although I have shown Vand described an implement having two inclined axles e2, it will be obvious that an implement can be made having only one such axle and tinewheel or pair of tine-wheels.
