To all whom it may concern: 7

Be it known that I, JOHX /lAr-rnn, a citizen of the United States, residing at Vallejo, in the county of Solano and State of California, have invented new and useful Improve ments in Lumber Slings, of which the following is a specification.

This invention relates to a lumber sling.

It is the principal object of the present invention to provide a lumber sling which is decidedly simple in construction and may be readily applied and removed from lumber which it is intended to be used in lifting.

The present invention contemplates the use of a long splice member having a loop in each end and slidably carrying a short splice and a hook; the short splice being also fitted with a hook by which the parts may be instantly connected or disconnected during operation.

The invention is illustrated by way of example in the accompanying drawings, in

which Fig. 1 is a view in elevation showing the complete invention.

Fig. 2 is a view in end elevation showing the application of the present invention.

Referring more particularly to the drawings, 10 indicates a long splice member.

which comprises a cable, the ends of which form

loops

11 and 12. Secured upon the cable 10, at a point intermediate its looped ends, is a choke shoulder 13 adapted to limit the movement of a short splice cable 14; This cable is slidably looped on to the long splice at 15. Its opposite end is fitted with Y a hook 16. The long splice cable is provided with a hook 17 slidably mounted thereon by means of a hook ring 18. r

In application of the present invention the short splice cable 14 is passed beneath a pile of lumber to be hoisted, or it may be laid flat upon the ground to receive the lumber. In any event the long cable 10 is doubled and is looped around the hook 16. Loop 12 of the longcable is then carried back and is passed over the hook 17 When the members are properly adjusted the loop 11 and a portion of the long cable will eX- tend from the center of the stack of lumber and may bereadily secured to a hoist as indicated in Fig. 2. When large objects are lifted the advantages of the choke shoulder 13 are evident as this prevents the looped end 12 of the cable from passing through or becoming tangled with the hook 1Q When the slin is applied, as shown in- Fig. 2, it

construction, combination and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as' claimed.

-Having thus described my invention, what ent is 1. A ,device of the. character described comprising a long cable. having loops in its opposite ends, a short cable slidably connected to the long cable, a hook on the end of the short cable, and a hook slidably mounted having a loop at each of its ends, a-stop shoulder fastened to the long cable at. a

point intermediate its ends, a short cable slidably. mounted upon the long cable between the shoulder and one of the loops, a hook slidably mounted upon the long cable between the short cable and said last named loop, and a hook secured to the end of the short cable. I w i 3. A lumber sling comprising a short cable adapted to pass partially around an object to be lifted, a hook upon one end of said short cable, a loop upon the opposite end of said cable, a long cable passing through said loop of the short-cable and formed at I being adapted to pass around the opposite its opposite ends with loops, said long cable I side of the object to be lifted and to engage the hook of the short cable, and a hook slidably mounted upon thelong cable and adapted. to receive one ot the ooped ends of the long cable, While the other looped end of said cable remains free to be engagedby a lifting device.

A lumber sling comprising a short cable adapted to pass partially around an object to belifted, a hook upon one end of said short cable, a loop upon the opposite end of said cable, a long cable passing through said loop of the short cable and formed at its opposite ends Withloops, said long cable being adapted to pass around the opposite side of the object to be lifted and to engage the hook of the short cable, a hook slidably mounted upon the long cable and adapted to receive one of the loopedends of the long cable, While the other looped end of said cable remains free to be engaged by a lifting device, and a stop on the long cable adjacent the hook engaging loop thereof.
