HAY-SLING.

SPECIFICATION forming part of Letters Patent No. 384,9(0, dated June 26, 1888.

No model.)

To all whom it may concern:

Be it known that we, ANDREW CHURCH and. CHARLES A. CHURCH, citizens of the United States, residing at Morenci, Lenawee county, Michigan, have invented certain new and useful Improvements in Hay-Slings, of which the following is a specification.

Our invention relates to that class known as sectional hay-slings, composed of two or moreropesparallelorconvergingat their ends, In hay-slings of this class the slingis first laid so that the ends extend beyond the ends of the wagon rack or bed. The hay or grain is piled on the sling, and the ends of the sling are then brought together above the hay, which is thus compressed into a bundle which may be readily hoisted and conveyed to any desired part of a mow orstack. In certain hay-slings of this class heretofore in use the cross-bars are entire and the ropes of the sling converge together between the two cross-bars nearest the center of the sling. These ropes are made fast at this point to a tripping device, which when operated permits the two halves of the device to fall asunder, allowing the released bundle to drop. It is found in practice that in this arrangement of crossbars with centrally-converging ropes between them the cross-bars press into the hay, sothat when the two halves of the sling are allowed to drop apart the two cross-bars nearest the center pull the bundle apart and carry with them a considerable quantity of hay, which is either scattered 1agbout or which must be pulled off from the ars.

A further disadvantage of the sling here referred to is the shortness and rigidity of the cross-bars, the length of which is of course limited somewhat by the width of the wagon bed or rack upon which the sling is used.

The objects of our invention are, first, to obviate the difficulty here pointed out. and, secend, to provide a convenient and reliable triplock for our device. XVe attain these objects by means of the mechanism and arrangement of parts shown in the accompanying drawings, made part hereof, in whieh-- Figure 1 is a plan view ofour device aslaid upon a wagon bed or rack to receive its load; Fig. 2, a side elevation showing the sling sus Like letters represent like parts throughout the several views.

From each of the rings a lead two ropes, b, and a third rope, I). Ropes b, at their ends opposite from the rings, are attached to one of the pieces of sectional crossbar, and rope b terminates in a loop which slips loosely over the outer end of that section of the cross-bar to which the opposite group of ropes 1) 1s attaehed. (See Fig. 1.) Section 0 of the crossbar is provided at its inner end with a triplock, d, designed to engage an eye or ring, 0,

on the inner end of section of cross-bar 0, thus forming a joint which permits the cross-bar to conform somewhat to the bottom of the wagon bed or rack and permitting the cross-bar to partially embrace the sides of the load.

The locking device d is tripped and unlocked by means of cord 6 in the. hands of the operator.

The case 'of lock 01 is provided with a mortise to receive the end of bar 0. y

f is a hooked bolt oscillating on pin 9, pro vided with opening l2,i'orming a jaw to receive the loop or ring 0" on bar 0.

13 is a sliding stop to which cord e 18 attached, which stop, being slipped under shoulder 7c of bolt f, locks the jaw h against the inner side of the lock-case, asin Fig. 4, prevent ing oscillation of the boltf and escape of ring a". Stop i being withdrawn, as in Fig. 5, by a.

pull on cord e, the weight of ring 0 and its appendages causes bolt f to perform part of a revolution, opening jaw h and releasing ring 0.

Z is a coiled spring, one arm of which, Z, presses against the shoulder is of bolt f, so as to tend to keep jaw h openeonstantly. The springs other arm, l, engages sliding stop 6, exerting a constant pressure thereon in the direction of boltff. When ring a is pushed against the back of jaw h, the pressure of spring-arm Z is overcome, jaw h is closed, shoulder 70 is moved so that spring-arm Z forces sliding stop 2' forward under shoulder k, catching and holding the hooked bolt in position.

When cord 6 is pulled, the reverse operation takes place. The pressure of spring-arm Z is overcome, sliding stop i is withdrawn, boltf is tripped, and ring 0" is released, the jaw standing open until the ring is again introduced.

The. sling being first arranged as shown in Fig. 1, and the sections of cross-bar c 0 being united by locking ring 0 into lock d and slipping the loops of ropes I) over the outer ends of sectional bar a c, the sling is now drawn taut around the bundle of hay to be handled and the load is suspended by rings a from the usual pulleys and carriage and conveyed to the point where it is desired to drop the bundle. Cord e is now pulled, lock (1 is tripped, as hereinbefore described, the sections of cross-bar c 0 fall apart, the loop on the end of rope b slips from its place, the two halves of the load may be dropped, are not new, and we do-not therefore claim, broadly, a sectional cross-bar; but

What we claim as our invention, and desire to secure by Letters Patent, is-- 1. In a hay-sling, a single central sectional cross-bar composed of two sections meeting purpose specified.
