ABRAHAM IVIOYER, OF MOYERS, OKLAHOMA.

WAGON-BED I-fOIST.

To all whom it may concern:

Be it known that I, ABRAHAM MoYnR, a citizen of the United States, residing at Moyers, in the county of Pushmataha and State of Oklahoma, have invented certain new and useful Improvements in lVagon- Bed Hoists, of which the following is a specification.

This invention relates to wagon-bed or body hoists, and pertains especially to the class of such hoists which carry the hoisting drum or windlass with them during a rais ing and lowering operation.

This invention is designed as an improvement on Patent No. (362,800, issued to me November 27, 1900, and involves certain elements not found in said patent, and comprises such arrangement of parts as to furnish improved results over the said patent.

The object of the invention is to provide novel and peculiar means for connecting a hoisting frame with the hoisting sheaves or pulley blocks.

A further object of the invention is to provide a special hanger for the hoisting mechanism, peculiar connections between the hanger and the hoisting frame, and improved construction and arrangement ofthe hoisting frame having depending grapples or hooks.

Other objects, advantages and improved results are attainable in the practical application of the invention.

In the accompanying drawings forming part of this application: Figure 1 is a side elevation partly broken away. Fig. 2 is a top view with the pulley-blocks removed. Fig. 3 is an enlarged section showing a pulley-block connected to the hanger. Fig. 4 is a detail perspective view of the hanger. Fig. 5 is an enlarged section taken through one corner of the frame.

The same reference numerals denote the same parts throughout the several views of the drawings.

The hoisting frame comprises longitudinal beams 1, connected by central crossbeams 2, and end cross-beams 3. A drum or windlass 4 is revolved between the central beams 2 by a shaft 5 journaled in said beams 2 and the end beams 3. Said shaft has a suitable crank-handle 6, and a ratchet-wheel 7 controlled by a pawl 8. At each corner of the frame a vertical bolt 9 extends Specification of Letters Patent.

Application filed December 14, 1909.

Serial No. 533,088.

through the ends of the beam 1, preferably upon the outer side of the beams 3. The rods or bolts 9 are provided with a nut 10, and the head of the bolt 9 holds an eye, ring, or link 11, to which are attached chains 12, having grapple hooks 13.

The device for attaching a double pulleyblock 14, consists of a hanger 15 having a central plate 16 and provided with an elongation 17 through which the eye 18 of the block 14 extends, and having a depending guide or fender 19 for the windlass rope or cable 20; a semi-circular bar 21 projects from each end of the plate 16, and these bars hold one end of suspending rods 22. The rods 22 extend diagonally from the bars 21, through the cross-beams 3, and the bolts 9 extend through this end of the rods. A bolt or key 23 fits the block-eye 18 and has a chain 24 for connecting it with the rope fender 19.

The rope or cable 20 has one end attached to a pulley-block 25, adapted to be suspended as desired or as occasion may demand. Said rope extends from the block 25 through the block 14, through the block 25, and again through the block 14 and through the fender end of the hanger to the drum or windlass.

It will be seen that the peculiar arrangement of the rods 22 not only connect the hanger with the frame, but they securely brace the frame diagonally, so that the weight of the bed or body in a hoisting operation is distributed at the four corners of the frame.

It is obvious that the frame may be connected and disconnected so that it may be removed and replaced for raising or hoisting a vehicle body, bed or box, by simply operating the hanger-key. It will be understood that the hanger may be attached to this frame or a similar hoisting frame by simply connecting the rods with the corner bolts.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination, with a hoisting frame comprising longitudinal beams, central cross beams, and end beams, corner bolts connecting the longitudinal beams, a windlass, and means for revolving it between the said central beams, of a plate hanger, and suspending rods having one end secured to the hanger and extending diagonally and downa wardly therefrom with the other end of the pending from the plate and forming a guide rods projecting through the end beams and secured to the said bolts.

2. The combination, with a hoisting frame, corner bolts connecting the frame parts, a Windlass, a block and tackle device, and a series of rods having one end attached to the bolts and projecting upwardly and diagonally therefrom, of a hanger comprising a central plate having an elongation in which is secured said block, a tender defor the Windlass rope, a bar projecting from each end of the plate to which bars the other end of the rods are secured for fixing the 15 hanger over the Windlass.

In testimony whereof I aflix my signature in presence of two witnesses.
