ABSTRACT:
A double cable reel utilizes a cylindrical core and a pair of flanges affixed thereto. The reel, thus formed, is journaled to a cover plate and has two pair of wiper and contact washers arranged in concentric arrangement such that one pair is secured to the cover plate adjacent thereto. A cam drum is journaled so as to have its longitudinal axis aligned parallel to the longitudinal axis of the core and displaced radially outwardly therefrom. The cam drum is frictionally coupled to one of the flanges of the reel. Electrical contacts or terminals both of the stationary and the rotating variety are secured to the washers. The cam drum has a cam follower coupled into the double helical cam path located on the exterior surface thereof such that a double cable is wound up on the reel in a multi-layer helical path, such that one end of the cable is electrically connected to the pair of rotating terminals. Convenient mounting apparatus are provided for the apparatus whose major parts are easily disassembled facilitating cleaning and maintenance operations.
