Specification of Letters Patent.

Patented Nov. 1%, 1916.

Application filed March 23, 1916. Serial No. 85,287.

This invention relates to slings employed for elevating and conveying hay and other loads, and its object is to provide a novel and improved attachment whereby the load is borne by both ends of the sling.

With the object stated in view, the invention consists in a novel combination and ar rangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing, Figures 1 and 2 are perspective views showing the application of the invention, and Fig. 3 is a detail in perspective.

Referring specifically to the drawing, 5 denotes the two lines of a sling which are connected at one end to a loop attachment 6 by means of a hook 7 on the latter, and at their other end to the frame of an elevating pulley 8 around which pulley the rope 9 of an elevated carrier or other similar apparatus (not shown) passes. The loop attachment 6 is of the type illustrated in Patent No. 739901, dated September 29, 1903, the same carrying guide pulleys 10, said pulleys being carried by a pivoted arm 11 provided with a bolt 12 whereby it is locked to the loop. The arm is pivoted on a shaft 13 carried by and extending between the branches of the loop, and on said shaft are also mounted pulleys or rollers 14:. A. trip device is provided for operating the bolt 12 to release the arm 11 so that the latter may swing clear of the loop to allow the pulley 8 to pass therethrough.

In use, the lines 5 are passed around the load to be elevated and conveyed. Before starting to hoist the load, the pulley 8 is below the loop 6 and the two ends of the hoisting rope or line 9 engage the pulleys 10. Upon starting the pull on the hoisting line, the sling lines 5 are drawn tight around the load and the latter is compressed, and then lifted and conveyed to the desired place. As the pulley 8 approaches the loop, the bolt 12 is tripped to release the arm 11 and the latter now swings clear of the loop so that the pulley may pass therethrough, the two ends of the hoisting line 9 now passing to the pulleys or rollers 1%. These parts, and their operation as described are the same as in the patent hereinbefore referred to.

lVith the loop attachment 6 hereinbefore described, the entire load is carried by the two ends of the sling lines 5 which are connected to the pulley 8. The invention therefore has been designed to remedy this objectionable feature and to have the ends of are.

JOHN H. SANDMEYER, 33,01 CHENOA, ILLINOIS- the slin lines which are connected to the loop attachment also bear the load, so that both ends of the sling are made to support the load. This result is accomplished by anchoring the pulley 8 to the loop attachment after it has passed therethrough and the load has been compressed and is ready to be elevated. The frame of the pulley has therefore been provided with a hook adapted to engage the loop, preferably the pulleys or rollers 14: located between the branches thereof. The pulley frame, indicated at 15, has at the bottom a lug 16 which is straddled by two laterally spaced lugs 19 on the inner ends of the shanks 20 of two hooks 21, said shanks being connected at their inner ends and extending divergingly therefrom to laterally space the hooks 21, which latter extend in the same direction. A third hook is provided, the same being indicated at 22 and having a shank 23 which is located between the shanks 20 and is connected to the inner ends thereof. A cross bar 24: connects the shanks of the three hooks near their outer ends. The hook 22 extends in the opposite direction from the hooks 21 and is designed to be engaged with one end of the sling lines 5, the other end being connected to the loop 6. The hooks 21 are so positioned that they are intercepted by the pulleys or rollers 14. upon passing through thealoop 6, and when they engage said pulleys or rollers, the pulley 8 is anchored to the loop 6 with the result hereinbefore described, and entirely clear of the loop so that the hoisting line 9 may run freely over said pulley, the hooks being a sufiicient distance below the pulley to leave the same spaced and above the loop.

I claim y The combination with a sling, a hoisting line, a pulley over which said line passes and to which one end of the sling is connected, and a loop attachment to which the other end of the sling is attached, and through which the pulley is adapted to pass; of a pair of laterally spaced hooks carried by the pulley and adapted to engage the loop when the pulley has passed therethrough and cleared the same, said hooks being spaced vertically from the pulley, and another hook carried by the pulley for attachment of the first-mentioned end of the sling, all of the aforesaid hooks being integrally connected, and the shank of the second-mentioned hook being located between the shanks of the first-mentioned hooks, said second-mentioned hook extending in the op posite direction from the first-mentioned hooks.

In testimony whereof I efiix my signature.
