' HOISTING SLING Filed Aug. 1, 1930 ATTORNEY.

Patented Sept. 22, 1931 warren stares n Ar ALARIK LUNDQUIST, PORTLAND, OREGON HOIS'IING SLING Application filed August 1,

The invention relates to improvements in hoisting slings especially adapted and arranged for use in conjunction with hoisting apparatus, the primary object of the invention being to provide a simple and efiicient device of this character, capable of economical construction and highly etlicient in use.

Another object of the invention is the provision of a hoisting sling of the character indicated, so constructed and arranged-as to prevent injury or damage to the. packages hoisted.

Another object of the invention is the provision of a hoisting sling of the character indicated, having improved means of attachment or connection with a hoisting element.

Other objects will appear hereinafter.

The invention consists of the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in -which V Fig. 1 is a perspective view of a hoisting sling embodying the invention, and shown in position of use, and r Fig. 2, a similar View of a modified form of construction.

The form of construction illustrated in Fig. 1 of the drawings comprises a relatively wide flexible belt 3, preferably of cotton, leather, or the like, and adapted and arranged to embrace or encircle the objects or articles to be hoisted. The belt 3 is provided at one end with a back-turned loop, or flap, 1, se-

cured thereto as indicated by suitable rivets, and forming a securing loop 5. A transverse rod is mounted as shown in the loop 5, said rod being provided at opposite ends with eyes 6, swiveled to the ends 7 of the flexible loop 7 preferably in the form of a wire rope,

or cable, has its ends securedto the eyes 6,

and is adapted and arranged to detachably engage the hook at the end of a hoisting cable 9 or the like.

The strap 3 is provided at its other end also with a back-turned flap 10, forming a securing loop 11, in which is mounted the transverse rod 12' having protruding ends bent'to or objects, such as'sacks of sugar, grain, and u p the like, ior hoist ng purposes, and which .jVlll not tear or Cllll Sitld SaCliS, or other objects 192.0. Serial No. 472,304.

,form hooks 13, adapted and arranged to slidably engage the sides 01': the loop 7 as shown. by this arrangement, aslip-noose is formed which may be readilypl'a-ce'd around articles engaged. The sling disclosed will be found to be especially adapted for use in loading and unloading ships; is of great strength; is waterproofjand',nonkinkable; and may be readily applied to or reniovedfrom the object hoisted. Thewire, cables, or ropes, in

the sling,n iay be readily replaced when necessary, and the sling wlllthus last a long time.

7 1 second flexible loop 1 1, preferably of rope, is also passed through the securing loop ll,and twisted togetherat15 and forming an eye 16. Another loop 17 also preferably of rope, is passed through the securing loop 5, as

shown. MAS the sling is emptied, the loop 1 1- 16 is looped through the loop 17, and the sling is 'returned to loading position by engaging the loop 17 with the hook 8. The loops 1l-16 and 17 may also be employed to advanage in manipulating the sling when placing it around or removing it from the object' to be hoisted. This form of the device is especially adapted for use in loading into railroad cars or narrow quarters Where the belt is liable to be rubbing against doors, and the like, and thus wearing out.

In the form'of construction illustrated in Fig. 2, the'belt 3 is provided at each end with triangular metal loops 18 and 19 secured to securing loops 11' and 5, as indicated. The loop 18 passes through atube orpipe 18 which prevents rubbing against loop 11 and furnishes additional reinforcement. The loop 19 is adapted and arranged to engage a double hock 2O loosely pivoted at the apex of the tringular metallic loop 21, adapted and arranged to slide upon the body of the belt 30, as shown, the base .of the loop 21 being provided wih a roller 22 to facilitate such slidingj This arrangement forms a simple and efilcient slip-noose construction which may be readily applied to or removed from the objects to be hoisted. This form of'con-- 100 struction is especially adapted for use in situations Where there is no especial danger of rubbing, and is especially adapted for use in loading such things as lumber, paper, etc., Where there is little or no. swaying or swinging against sides of the hatchways of the ship, or the like. The loose hook 20 Will not tear or mar the enclosed objects or other parts of thesling. f

While I have illustrated and described the preferred forms of construction for carrying my invention into effect, these are capable of variation and modification Without departing from the spirit of the invention. I therefore do not Wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall Within the scope of the appended claims.

' Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent is:

1, A hoisting sling comprising a flexible I belt; metal loops secured to'the ends of saidbelt; and a loop slidable on the body of said belt, and having a hook detachably engaging the loop on one end of said belt.

.2. A hoisting'sling comprising a flexible belt having its ends turned backwardly upon itself to form securing loops; triangular metal loops secured in said securing loops a triangular metal loop slidable on said belt, a hook being formed at the apex thereof'to detachably engage one of the loops on an end of said belt; and a roller mounted on the base of said slidable triangular loop, said roller slidin against said belt. 7

n Witness whereof, I have hereunto set my hand this 21st day of July, 1930.

ALARIK LUNDQUIST.
