Abstract
1,273,436. Spring drum balance apparatus. LANGSTILL Ltd. 20 July, 1970 [30 Aug., 1969], No. 43264/69. Heading B8B. A load balancing device comprises a load cable drum mounted for free rotation on a shaft 16, a spiral spring connecting the drum to the shaft so as to be tensioned during rotation of the drum in the paying out direction, a device 26, 27, 28 for pre-tensioning the spring, and a safety device 39 preventing rotation of the drum in the paying out direction when the spiral spring tension is released, e.g. by spring breakage. The safety device comprises a catch member 39 which is movable into engagement with one of a series of locking notches 43 formed on the periphery of the drum to brake the same, when the spring tensioning device shaft 28, to which the member 39 is secured, is moved downwardly in Fig. 1 by a spring 34, once the spiral spring tension is released. The spiral spring is tensioned by a handle 38, which through the shaft 28 operates a worm-wheel gear 27, 26 associated with the shaft 16, this tensioning tending to force the shaft 28 and worm 27 upwardly in Fig. 1 against the bias of the spring 34.
