I, Specification of Letters Patent.

Patented Sept. 8, 1914. Divided and this application' filed ()ctober 21,

1911. Serial no. 655,882.

'en of the United States, residing in the of New York, borough of Manhattan, county 1'- zad State of New York, have invented a certain new and useful Device for l andling Freight in Packages, of which the llowing is a specification.

This ii iention is a sling for handling 11 erchandise contained in barrels, and similar packages, wherein the barrels are suspended in such manner that they cannot beome disengaged from the sling during the operation of hoisting them.

llhe invention of this application is a division of a prior application filed by me on August 9th, 1910, Serial No. 576,353.

The invention embodies two rigid loadengaging members each provided with two hooks adapted to engage eparately. with the two barrels, or other packages, to be hoisted, and a single flexible connection engaging loosely with said load-engaging members, said flexible connection being adapted to exert strain uniformly on the load-engaging members in such manner as to draw them firmly into engagement with the components of the divided load.

Other features of the invention, and the advantages thereof, will appear in the course of the following detailed description taken in con ection with the drawings.

in the accompanying drawings, 1 have illustrated one practical embodiment of the invention, but the construction shown there in is to be understood as illustrative, only, and not a defining the limits of the invention.

Figure 1 is a perspective view of a sling for hoisting barrels in accordance with this invention. Fig. 2 is a side view illustrating the positions of the parts when hoisting, and F 3 i a detail front View of one of the load-engaging members.

A, B designate the load-engaging members and G the flexible connection, the said parts comprising the sling of this invention. Each load-engaging member is preferably triangular in form, and is composed of metal, preferably bar or rod metal, the same being bent to form an eye or ring (5 at the upper middle part of the member. From this ring or eye, the arm of the mem er diverge in a downward direction, each arm being provided with a hook or claw e. As

an upward direction.

shown, the lower part of each arm is widened and bent outwardly and then upwardly, so that the hook or claw is positioned on one side of the arm and faces in The claw shown is wider than the arm and is provided with iilpwardly pointing teeth, whereby the claw is adapted to so firmly engage with a barrel, at the chime thereof, as to preclude slipping. The flexible connection is composed, preferably, of a rope, cable,- or the like Said connection extends loosely through the eyes cl of thetwo load members, the ends of said connection being united so that the connection is in the form of a loop.

My sling is used as follows: The two members are positioned at the respective ends of the; two barrels X, Y-to be hoisted, said members extending transversely to the barrels so that the hook at one end of each member will engage with one barrel and the hook at the opposite end of the member e11- gages with the other barrel. The members thus span or bridge the space between the barrels constituting the load, and said mem bers extend upwardly from the load, at the ends thereof. The loop or connection G extends between the members so as to unite them, and when the load is suspended during the hoisting operation, said loop draws upon the members so as to move them to the inclined positions shown in Fig. 2.

Preparatory to hoisting the load, the hook f of a fall block F is engaged with the loop C, and the load is raised or lowered by the operation of a fall rope G, the latter being reeved through the fall block. The pull of the fall-block hook f is exerted cen trally on the upper member of the loop 0 so as to result in the member assuming the tri angular form shown in Figs. 1 and 2, and this flexible loop in turn imposes strain uniformly on the two'load-engaging members, whereby the claws are pulled into tight engagement with the barrels composing the load and said barrels are caused, by the weight thereof when the load is suspended, to impinge against each other. The members are thus held into engagement with the barrels so securely that the load cannot become accidentally dislodged from the sling when hoisting the load, but when the load is deposited upon a floor, dock, or other surface, and the strain is relaxed on the fall line, the claws of the members can be readily disengaged from the barrels, or the members will. themselves drop away from the barrels so to become disengaged there from automatically.

The sling is simple and strong in construction, economical to manufacture, and easy and. rapid of manipulation so as to connect it to, or detach it from, the barrels. The sling may be used in many places, such as the hatchways of vessels and of stores and warehouses, and it aitlords a simple and efiicient means for rapidly and economically handling freight in barrels, or analogous containers.

Having thus fully described. the invention, what I claim as new, and desire to secure by Letters Patent is 1. In a sling of the class described, the combination of a plurality of rigid load-en gaging members each having upwardly converging arms and provided at their lower ends with upwardly facing hooks or claws, said load-engaging members being positioned to span the space between two barrels of a load and the hooks or claws of each member being adapted for engagement with the respective barrels at the ends thereof, a single flexible loop loosely engaged with the upper portions of said load-engaging members, and a fall line detachably connected to the upper part of the loop at a point between, and equidistant from, the rigid load-engaging members.

In a sling of the class described, the combination of two substantially triangular load-engaging members each composed of rigid material and each provided at the upper part with an eye and at the lower parts thereof with upwardly pointing claws, a single flexible loop running loosely through the eyes of the respective load-engaging members, said load-engaging members being positioned to span two barrels of a load, and a fall line connected with the loop so as to exert stress thereon. between the load-engagin;- members so that the load-engaging members will draw the components of the load into contact with each other.

In testimony whereof I have signed my name to this specification in the presence oi two subscribing witnesses.
