Abstract
380,215. Safety devices for lift cages. HUSBAND, W., 5, Upper St. Albans Terrace. and BOWEN, 1., Tynewydd Hotel, both in Treherbert, Rhondda Valley. May 4, 1932, No. 22037/31. [Class 78 (iii).] In a safety device for lift cages a spring-operated wedge b, connected to the hoisting rope by a chain a, falls when the rope breaks and forces arms c, having lugs engaging grooves f in the back of the wedge, outwards so as to press rope guides d against members e on the cage and arrest the movement of the latter.
