ABSTRACT:
Apparatus for routing a resilient cable of specified length, such as an electric power transmission cable, across a rotary joint between first and second members, wherein the first member is supported for rotation with respect to the second member. The apparatus includes a first guide element disposed to rotate with the first member, for guiding a first component or portion of a cable along a first arcuate path of specified radius, the length of the first cable component disposed to vary as the first member rotates. The apparatus further includes a second guide element, in fixed relationship to the second member, for guiding a second component of the cable along a second arcuate path, the length of the second cable component disposed to vary in inverse relation to the length of the first cable component. The first and second guide elements are mounted in spaced-apart relationship, to provide a spacing therebetween which is selected to form a third component of the cable, extending between the first and second cable components, into a loop of specified configuration. The first and second guide elements are provided with first and second annular channels, respectively, each arcuate cable path lying along a portion of one of the annular channels.
