Abstract

3435. Beccat, G. Feb. 10. Self-sustaining gear. - Comprises a self-sustaining gear for hoisting-apparatus in which a loose brake drum carrying coiled cable is arranged between the axially-movable operating- member and a friction disk keyed to the driving or drum spindle. The drum spindle a carries a disk c, the boss of which is screw-threaded to receive the operating-pulley d. The brake drum h is mounted between a flange on the disk c and the boss of the pulley d, a leather washer g and a zinc washer i being provided. A collar f is secured to the end of the spindle a. A cable is coiled round the drum h, one end being fixed to the framing by a rod l, while the other end is attached to a spring m, the tension of which can be lessened by operating a cam o. Hoisting is effected by turning the pulley d so as to squeeze together the drum h and washers against the disk c. The brake does not come into action as the hoisting movement tends to uncoil the cable. Any tendency of the load to run down increases the friction of the cable. To lower, the tension of the cable is released by operating the cam o. The speed of lowering may exactly correspond to the movement of the pulley d by maintaining the proper tension on the spring m, any tendency to over-run locking the members together again.
