  • Patent number: 3934397
    Abstract: A wire rope or cable splice assembly particularly for long splices in wire ropes or cables for uphill and overhead transportation systems such as ski lifts, overhead cable rides and the like. Cable ends to be joined together in such assemblies are frequently spliced by cross tucking corresponding strands of opposite ends of the cable into the core space at spaced regions along the cable length, the number of such tuck regions corresponding to the number of strands in the exterior lay of the cable. The invention provides a novel assembly of a protective metallic sheath for the portion of each strand tucked into the core space, as well as a void filling back-up member for the void formed in the tuck region or zone of crossover of end portions of corresponding strands of spliced opposing cable ends.
