JOHN M. KELSO, OF MEXICO, MISSOURI.

DEVICE FOR HOiSTING WAGON-BEDS.

SPECIFICATION forming part of Letters Patent No. 386,323, dated July 17, 1888.

(No model.)

To all whom it may concern.-

Be it known that 1, JOHN M. KELSO, a citizen of the United States, residing at Mexico, in the county of Audrain and State ofMissouri, have invented certain new and useful Improvements in Devices for Hoisting Wagon-Bodies, of which the following is a specification.

This invention relates to that class of wagonbody hoists comprising a rope carried by overhead pulleys and provided at one end with a sling to receive the end of the wagonbody and at the other end with a Windlass or winch to wind the rope.

The invention consistsin providing the pivoted crank-arm of the Windlass with a hook to engage the rope or the wagon-body and prevent the unwinding of the rope on the drum of the Windlass.

In the accompanying drawings, Figure 1 is a side elevation showing my improved wagonbody hoist in position to raise the body or box of a wagon. Fig. 2 is an end elevation looking toward the sling. Fig. 3 is a detail side elevation showing the hook of the crank-arm in engagement with the rope. Fig. 4 illustrates the inner parts in detail.

In carrying out my invention two grooved pulleys, O, are secured overhead to any suitable support or supports in a wagon-shed or other covered structure at a distance apart equal approximately to the length of the body or box of an ordinary farm or lumber wagon. Reeved through the pulleys is a rope, B, connected at one end with the center of a sling or stirrup, A, consisting of a flexible loop, a, the ends of which are connected to the ends of a straight foot-piece, a, of a length slightly exceeding the width of the wagonbody. The rope B is secured at its other end to the drum or shaft D of a Windlass, having pivoted thereto a crank-arm, E, provided at its outer end with a handle, G, and at the side opposite the handle with a hook, F. The shaft of this Windlass is provided about midway of its length with a collar, I, and is tapered toward its inner end, as shown.

The cross-sills K K at the rear end of the wagon-body are provided, respectively, with centrally-arranged closed and open loops J and H, (see Figs. 1 and 4,) forming bearings for the Windlass-shaft D, and the collar I on said shaft is so arranged as to fit snugly behind the rearmost or open bearing, H, when the Windlass-shaft is in operative position and prevent the accidental endwise movement of said shaft.

In operation a wagon is run into the shed beneath the pulleys O of the hoist. The sling or stirrup A is then passed over the front end of the wagon-body and the shaft D of the Windlass is fixed in its bearings H J. The handle G is now operated to wind the rope B upon the shaft, thus raising the wagon-body sufficiently above the truck to permit the latter to be moved out. The rope B is now passed into the hook F of the crank-arm E to lock the shaft D against rotation, thus suspending the wagon-body securely until released by hand.

I am aware that it has been proposed in devices of this general character to pivot a crank-arm to the winding drum or shaft, the shaft being looked after the wagon-body has been raised by resting the handle at the outer end of the crank-arm against the rope or chain, and this construction I do not claim. Myinvention differs from this construction in that the crank-arm is provided with a hook to embrace the rope, thus locking the shaft positively against rotation in either direction and preventing the accidental release of the crankarm. Aside from this, as the hook projects from the crank-arm in a direction opposite the handle the shaft can be secured at halfturns, ifdesired, as at one half-turn the book will be in position to receive the rope and at the next half-turn the handle G can be rested against the rope, as in the device hereinbefore acknowledged; or the crank-arm can be folded back to cause either the handle or hook to engage the under side of the wagon-body.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-- 0 In a Wagon-body hoist, the combination, with the overhead pulleys, the rope provided at one end with a sling and at the other end with a Windlass-shaft adapted to fit in bearings secured to the wagon-body at one end, of tion in either direction, substantially as dea crank-arm secured by a transverse pivot to scribed. the outer end of said shaft and having a han- V dle projecting at right angles from its outer 5 end and a hook arranged at the opposite side Witnesses:

thereof to embrace the ro e, whereby the DANIEL D. WooDWARD, shaft may be positively locked against rota- Jos. M. CooNs.
