SLING.

Specification of Letters Patent.

Patented Oct. 6, 1914.

Application filed May 17, 1912. Serial No. 697,996.

To all whom it may concern:

Be it known that I, Faann E. SLUTMAN, citizen of the United States,'residing at Brentwood, in the county of Contra Costa and State of California, have invented certain new and useful Improvements in Slings, of'which the following is a specification.

This invention relates to a sling especially adapted to be used in conjunction with overhead cranes or telpher systems for the purpose of'holding material while it is being moved from point to point. The sling is especially adapted to be used for holding sticks of timber, bars of metal, or other relatively long and narrow objects.

With the above objects in view, the slim consists of frames composed of L-shaped sections pivotally connected together and adapted to engage or interlock with each These frames areconnected with the end portions'of a connecting bar. Supporting chains are connected with the connecting bar and are adapted to be engaged with the hook of the crane or other lifting apparatus.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing in which Figure 1 is an enlarged edge view of the sling; Fig. is a side view of the same,

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The sling consists of a connecting bar 1 to the end portion of which are attached supporting chains 2. These chains are adapted to be connectcdnvith the hook of a lifting apparatus. Chains 3 are connected with the endportions of the bar 1, and the lower "ads of the chains 3 are connected n ith th opposite sides of frame sections at the upper ends thereof.

The frame sections are indicated one at 4 and the other at o. 'lhese frame sections are L-shaped in edge elevation, and the frame section 4 is pivoted to the frame section 5 at the point 6. The frame section 4 is provided at its upper corner with an eye 8, and the lower ends of the chain 3 are connected with the said eyes 7 and 8, as shown. The eye/8 is provided with angularly disposed flanges 9 which extend along the outer sides of the angularly disposed portions of the frame section 4 and brace the same. An angle iron 10 is secured to the corner of the frame section 5 and extends along the outer sides of the angularly disposed portions thereof and braces the same. The lower end of the frame section 4 is beveled at its inner side as at 11, and the engagement of the head 13 with the lower edge of. the opening 12 so that the free ends of the frame sections 4 and 5 will be held together when the frame sections are sustalning the weight of a load.

V hen the sticks of timber or similarmaterials are supported by the frames and have been transported to a desired point, the sling is lowereduntil the lower side of the frame section 5 comes in contact with the ground or the ends of the sticks of timber are brought in contact with spaced supports. Then the flexible member of the crane is permitted to slack and the frame sections are permitted to swing down on the pivot 6 with relation to the frame sections 5. A crowbar or other implement is then inserted between portions of the frame sections 4 and 5 which normallv are in vertical ositions. A chain section 16 is connected with the eye 15 upon the frame section 4, and a chain 17 is connected with the eye 15 upon the frame secthe sling should assume the inclined position. The chain sections 16 and 1.7 are passed over the load and the bar 18 is inserted through one of the links of the chain section 16 and is then swung'back andthe ring 19 is slipped over the end of the bar 18,.

whereby the bar is held and the ends of the chain sections 16 and 17 are connected together over the load.

Having describedthe invention, what is claimed as new is:

1. In a sling, frame-sections, each including members rigid with respect to each other and extending substantially at right angles to each other, pivotal connection between the upper member of one of the frame-sections and the vertical member of the other framesection, a latch for connecting the lower end of the vertical member of the first mentioned frame-section and the lower member of the second mentioned frame-sect1on, and suspension means connected at the upper ends of the vertical members of the said frame-sections.

2. In a sling, frame-sections, each including members rigid with respect to each other and extending substantially at right angles to each other, pivotal connection between the upper member of one of the frame-sections and the vertical member of the other framesection, a latch forconnecting the lower end of the vertical member of the first mentioned frame-section and-the lower member of the second mentioned {frame section, a binder chain connected adjacentthe lower end of the vertical member of the firstmentioned frame section, a binder chain connected ad-. jacent the lower end of the vertical member of the second mentioned section, and means for connecting the ends of the chains.

In testimony whereof I aflix my signature in presence of two witnesses.
