Abstract
Abstract A method of providing a strong field splice for a wire rope sling, and the like, involving the steps of taking the preformed wire rope and unravelling a selected length of the end of the rope, forming two groups of strands, and reweaving them together in the form of the loop; and when the reweaving is completed, the two remaining ends are woven together to again form the original wire rope. This dead end is clamped to the live portion of the wire rope by means of a streamlined clamp.

Claim 1
Independent Claim
179 words
The method of field forming a loop splice at the live end of wire rope comprising the step of: (a) unravelling a selected length of said live end of wire rope to form two bundles of wires, with substantially the same number of wires in each bundle; (b) forming a left-hand loop about the live end with one bundle and a right-hand loop with the other bundle; (c) reweaving the two bundles in the loop to form a complete rope, until the loop is complete, and two bundle ends extend on opposite sides of said live end; (d) reweaving the two bundles to form a dead end rope; (e) positioning a top half of a clamp on said live-end; (f) positioning a bottom half of said clamp opposite said top half, the bottom half having a portion that slopes upwardly and so positioned that the sloping portion shields the terminus of the dead end; and (g) drawing and retaining said top and bottom halves together at two longitudinally spaced points on each side of said dead and live ends.
