Abstract
Abstract A rolling conductor support for supporting, guiding and protecting electrical, hydraulic, coolant and the like conductors extending between parts of machines which move relative to one another on guides or tracks. The conductor support comprises a plurality of parallel chains connected in laterally spaced relation by conductor supporting bridges to which the conductors are fastened by clips or retainer loops. The chains are composed of links pivotally connected at overlapping contiguous ends, with a slot in one end of each link receiving a stop pin in the overlapping contiguous end of the next link, the length of the slots determining the bending radius of the chains.

Claim 1
Independent Claim
188 words
A rolling conductor support comprising: a plurality of longitudinally extending chains connected together in laterally spaced apart relation by a succession of spaced apart bridge members extending therebetween, each chain including a succession of links having contiguous overlapping pivotally connected end portions, each pivotal connection having a pair of vertically spaced pivot parts extending laterally between and connecting together the overlapping end portions, the lower of said pivot parts providing a fulcrum for pivotal movement between the links, one of the overlapping end portions having a slot of determined length and the upper pivot part interfitting in said slot and fixed with respect to the other overlapping end portion and movable in the slot throughout the length thereof to limit pivotal movement between the links, alternate links of each chain including a pair of spaced parallel link plates embracing the contiguous overlapping end portions of the remaining links, and conductor retaining means comprising a plurality of rods extending through apertures in the chain links spaced vertically above said bridges and at least one stop pin projecting laterally through each rod to retain the rod against substantial longitudinal movement.
