Cable loop forming and hoisting device
First Claim
1. A cable retaining device for forming a cable loop around an article to be lifted or restrained, said device comprising, in combination, a cable having at least one free end, a cable knot block having a generally rectangular shape, a pair of similar parallel holes in an upper region of said block, a third hole in said block located at right angles to said pair of parallel holes, all said holes having a slightly greater diameter than the cable diameter adapted to receive the free end portion of said cable in fixed relation, a continuous lineal slot in said block formed parallel to said third hole to receive an intermediate portion of said cable beyond a sized lifting loop, said slot having a slightly greater width than said cable diameter, an enlarged recessed circular area formed in an upper terminating region of said slot, and a circular keeper member surrounding said cable fitted within said enlarged recessed area of said slot for positive retention of said cable therein.

Abstract
The present invention relates to a cable loop forming and hoisting device and, more particularly, to a cable knot block device adapted to forming a sized hoisting sling or loop in fixed relation which is capable of lifting or restraining various types and sizes of loads of varying weight. The device may be readily attached to the load and easily disconnected from the cable while positively retaining the cable in looped load-bearing locked-in relation.
