Abstract

225,835. Hauck, A. Dec. 8, 1923, [Convention date]. Coiling and uncoiling.-A vertically suspended cable or like flexible member, such as an electric cable 4 supplying stage lighting apparatus 2, is passed through, and secured to, the top or ridge of the arched or V-shaped bottom of a receptacle 1 so that, when the latter is raised, the slack portion of the cable is deposited in windings therein. The lighting apparatus 2 may be carried by ropes 3 passing over pulleys 5, 6 and connected to a balance weight 7, the sum of the weights per unit length of all the suspension ropes 3 being equal to half the weight per unit length of the cable 4. When the weight of the ropes 3 is too small, the correct weight may be obtained by means of an additional rope 8 passing over pulleys 9, 10.
