SLING.

SPECIFICATION forming part of Letters Patent No. 756,304, dated. April 5, 1904.

Application filed August 4, 1903.

To all whom, it may concern;

Be it known that I, FRANK LESLIE VVEB- STER, a citizen of the Dominion of Canada, residing at l/Vaialua, Island of Oahu, Territory of Hawaii, have invented certain new and useful Improvements in Slings; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in slings used in handling certain crops of merchandise and to that class of slings employing a separator or spreader.

On account of its construction and the ease and the rapidity with which it may be applied .and released my sling is particularly well adapted for use in loading sugar-cane in the field onto cars, as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 represents in perspective a bundle suspended in one of my improved slings. Fig. 2 represents in plan the spreader of same. Fig. 3 represents, on a larger scale, an end view of said spreader. Fig. 4: represents in perspective the rack used for loading my slings.

Similar letters of reference indicate similar parts throughout the views.

Referring to the drawings, it will be noted, Fig. 1, that the sling is composed of two ropes a a and the spreader Z). These ropes, preferably of light flexible wire cable, are of equal length and terminate in the rings a and c and e and 0, respectively, the rings sand 0 being connected together by the ring 0". The rope (4 passes through and is free to move in a staple (Z, attached to the spreader 6 near one end, while the rope (0 passes through and is free to move in a similar staple cl near the other end of the spreader. The spreader b is preferably made of pipe or tubing, and a notch It it is cut in the side of said pipe between its ends and the staples (Z cl, the notches being large enough to receive the rings c and 6' when the bolts inside the pipe are withdrawn, Fig. 2. In their normal position the bolts cover these notched openings, being held there by spiral springs g inside the pipe. These bolts project at f and f through slots Serial No. 168,196. (No model.)

cut in the pipe 6. A rack or frame (shown in Fig. 4:) made of pipes bent to shape is in two parts It and K1, the ends of one part, In, being small enough to slide inside the ends of the other part,

The mode of operation is as follows: The laborers pile the cut cane into the bundlingrack, which is made of such dimensions as to hold a suitable sling-load. The sling-ropes a (0 having been previously laid on the ground alongside the rack, the ring 6 at the free end of the rope a is brought up and over the cane in the rack and attached to the spreader b. This is accomplished by first withdrawing the bolt by means of the projecting end f, moved in the slot j against the action of the spring g, and next introducing the ring a in the notched opening it, and then permitting the spring to force the bolt through the ring a, locking same to the spreader. The ring 6' at the free end of the rope a is attached to the spreader in a similar manner. The rack may then be withdrawn, if desired, by separating its parts. The hoisting-rope now being attached to the ring 0 pulls the ropes a and a, drawing them through the staples snugly against the load. When the load has been landed in the car, by withdrawing the bolts by a tap on their handles f the rings a and a are instantly detached from the spreader Z2, and the sling is then withdrawn from the load.

While I have described my invention as applied to loading sugar-cane, it will appear that'it may be used for any similar crop or merchandise.

l/VhatI claim, and desire to secure by Letters Patent, is-

1. A sling for loading crops or the like, consisting of two ropes connected together at one end, a spreader having staples near its ends through which said ropes pass, and means for quickly connecting or disconnecting the free ends of said ropes to the ends of the spreader, substantially as described.

2. In a sling of the kind described,a spreader made of tubing 1), having a staple d, a notched opening it, out near its end, a bolt inside of said spreader its handle f projecting through a slot j, and aspring g for keeping said bolt normally over said notched opening, substanto this specificatidn in the ipieseiice dii two Sill) tially as described. scribing witnesses:

3. A sling of the kind described in combination with a bundling-rack in two parts 70 FRANK LESLIE WEBSTER 5 and k, for the purpose and substantially as Witnesses:
