Abstract

5917. Marks, E. C. R., [Roebling Sons Co., J. A.]. March 9. Slings. - A lifting- sling, Fig. 1, is composed of an endless wire rope 10 having eyes 11, 12, the eye 11 being adapted to pass through the eye 12. The rope is held by rings 14 and ears 2, or by a grooved clamping-piece 16. To protect the rope and permit inspection throughout its length, a series of short separate sleeves 17 are threaded thereon, the sleeves being preferably of different lengths to separate the joints on the two parts of the rope. The sleeves -may be connected at intervals, as at 4, to prevent the two parts of the rope from spreading apart. In a modification, Fig. 5, two such slings are suspended by the eyes 11 from a grommet 20, while other grommets 22 slide on the slings 18, 19 and carry hooks 21 for attachment to the eyes 12. In this form the sling ropes may be protected, as by lengths of helically-coiled wire 25. The hook 21 may be mounted on the eyes 12. Fig. 14 shows a further modification in which a wire rope grommet 26 slides on the sling rope by an eye 27, and is held round the load by a pin 28. The load is released by pulling a cord 30. Two such slings may be suspended from an eye such as 20.
