  • Patent number: 4966554
    Abstract: A continous cable is passed through a rotatable member which has axially adjacent non-rotatable members on both sides of the rotatable member. The continuous cable is coiled around one non-rotatable or stationary member, passed over deflectors mounted on and rotatable with the rotating member, passed through an opening in the rotatable member to a second non-rotatable member and is coiled around the second non-rotatable or stationary member. As the rotatable member rotates, the deflectors transfer the cable linearly from one coil to the other coil across the rotatable member, that is, through the opening thus maintaining continuity in the cable.
