Abstract
6598. Heap, R. S. March 21. Lifts.-Relates to lift-well doors and means for automatically operating them. The well door is divided horizontally into two parts e, e<x> connected by ropes, so that when the upper part rises, the lower drops. A rope f connected to the upper part e is led round five pulleys arranged in a box h at the side of the shaft, and its end is anchored. The pulleys j, k are movable in inclined slots i in the sides of the box while the other pulleys are fixed, and thus an upward movement of the pulley k or a downward movement of the pulley j opens the well door. These movements are effected by hinged projections o, o<x> on the cage adapted to operate the pulleys j, k respectively, according as the cage is descending or ascending. The rope f instead of being fixed direct to the door e, is secured to a catch p, Fig. 5, which, under the action of a weight q, normally locks the doors e, ex together, but is opened by the tightening of the rope f.
