HENRY W. WINTER, OF HENNESSEY, OKLAHOMA.

HARROW-DUMP.

Specification of Letters Patent. Patented Mar. 18, 1919.

Application filed December 14, 1918. Serial No. 266,724.

To all whom it may concern:

Be it known that I, HENRY WINTER, a citizen of the United States,residing at Hennessey, in the count} of Kingfisher and State of Oklahoma, have invented a new and useful Harrow-Dump, of which the following is a specification. t t 1 It is the object of. this invention to provide a novel but simple means, adapted to be attached to any harrow, for the purpose of raising the rear end of the harrow, when the harrow is advanced, to permit the teeth of the harrow to clear themselves of or be cleaned from, trash which the teeth may have collected. Within the scope of what is claimed, a ,mechanic may work changes, without departing from the spirit of the in vention.

In the drawings :-Figure 1 is atop plan wherein parts are broken away; Fig. 2 1s a longitudinal section wherein most portions of the structure appear in elevation.

The numeral 1 denotes a barrow of any kind, shown by way of illustration as 1ncluding a main beam 2, teeth 3, and the usual adjusting means 4. A rearwardly extended support or bar 5 is connected by clamps 6 to the beam 2 and is separated therefrom by spacers 7 The rear end of the support 5 carries a laterally extended stub axle 8 on which an eccentric crescent-shaped shoe 9 is journaled, the shoe including a base 10, which may be made in two parts, a plate 14 connecting the parts of the base and pro vided with a hub 15, a rim 11 united with the ends of the base, and a brace 12 extended between the plate 14 and the rim. The plate 14 is supplied with a lateral crank 16. A weight 49 is lodged in the angle defined by the forward end of the base 10 of the shoe, and below the Weight, the base supports a depending tooth 50.

The crank 16 is received in an elongated slot 17 formed in a head 18 at the rear end of a rod 19, constituting a part of the operating means, the rod being slidable in a bracket 20 on the support 5. There is an abutment 21 on the rod 19, and compression spring 22, surrounding a portion of the rod, bears terminally against the abutment 21 and the bracket20. The forward end of the rod 19 is pivoted at 23 to a rod 24 which, at its forward end, is pivoted at 25 to an angular pedal 26 including a footplate 31, the pedal being fulcrume-d at 27 on the main beam 2 of the harrow l, and being spaced from the main beam by a block 28. The lower end of an extension 29 is attached at 30 to the pedal 26 and bears against the footplate 31, the extension having a side proj ection 32 provided, with openings 33, adapt.- ed to receive a cord or wire (not shown) which, being rearwardly extended, forms a means whereby the structure may be operated front the rear, if the device be assembled with a walking harrow. In case a riding harrow is used, the pedal 26 will form the actuating means.

An upstanding inclined keeper 34 is mounted on the support 5. A latch 35 is fulcrumed at 36, intermediate its ends, on the base 10 of the shoe 9, one end of the latch being adapted to cooperate with the keeper, the other end of the latch having a projection 37 adapted to coiiperate with a projection 38 on the rod 19. A retractile spring 39 connects the outer end of the latch 35 with the brace 12 of the shoe.

When the pedal 26 is operated, the rod 24 moves forwardly and carries with it the rod 19, the spring 22 being compressed. The projection 38 on the rod 19 engages the projection 37 on the latch 35 and swings the latch out of engagement with the keeper 34, the shoe 9 thus being set free for rotation. Under the action of the weight 49, and under the pull exerted on the crank 16 by the rod 19, the forward end of the shoe moves downwardly until the tooth 50 engages the ground, whereupon the shoe will roll on its rim 11 and raise the rear end of the harrow, thus causing the teeth 3 at the rear of the harrow to clear the trash which they may have collected. When the rim 11 of the barrow rides clear of the ground, the shoe 9 will swing over into the position of Fig. 2, under the action of the weight 49, the spring 39 holding the inner end of the latch 35 in such a position that it will interlock with the keeper 34 and retain the shoe 9 in the position shown in Fig. 2 until the pedal 26 is again actuated.

I claim 1. In a device of the class described, a harrow; a rearwardly extended support carried thereby; an eccentric shoe journaled on the support and having a crank; operating means connected with the crank; a keeper on the support; a latch on the shoe and cooperating with the keeper; and interengaging elements on the latch and on the operating means for disengaging the latch from the keeper.

2. In it device oil the class described, a harrow; a rearwardly extended support carried thereby; an eccentric shoe ournnlcd on the support; a keeper on the support; a latch on the shoe and cooperating with the keeper; and a combined means for disengag; ing the latch from the keeper and operating the shoe.

3. In a device of the class described, a harroW; a reerwardly extended support f a ried thereby; an eccentric shoe journaled on the support; a crank on the shoe; an ope' ing means connected With the crank; a 1L or tnlcrumed on the llitll'OW and connected with the operating means; a. bracket on the support and receiving the operating means slidahly; an abutment on the operating means; acompression spring interposed between the abutment and the bracket; a. keeper on support; a latch on the shoe and cooperating with the keeper; and interengaging elements on the latch and on the operating means for disengaging the latch from the keeper.

In testimony that I claim the foregoing as my own, I have hereto athXed my signature in the presence of two Witnesses.
