Abstract: Apparatus for providing connection between two members having relative movement in a horizontal plane in a rotary or linear fashion. The apparatus includes a set of vertical surfaces affixed to each of the members, laterally aligned across a selected vertical gap. A number of cables or hoses, for electrical, hydraulic, or pneumatic connection are arranged between consecutive surfaces in a C-shaped traveling loop, connected through their end portions to the two respective members, so that through a sliding motion portions of the cable are transferred from between one set of surfaces to the other aligned set, across the gap, upon relative motion of the members. A number of flexible devices are affixed to the upper set of surfaces for supporting the upper portion of each looped cable.
