Abstract
539,682. Safety devices for lift cages. HECTOR, G. April 27, 1940, No. 7592. [Class 78 (iii)] In a safety device for pit and like cages in which a safety rope 8 secured to the cage tops passes over an idler pulley 1 supported in vertically movable bearings and adapted to apply a brake to the rope 8 on breakage of the main hauling rope, the brake comprises fixed members 20 and horizontally slidable members 17 adapted to grip the rope 8 between them. In one form, Fig. 2, the bearings. for the shaft 11 of the pulley 1 are formed in wedge members 9 supported by adjustable springs 14 on guide pillars 16 and engaging inclined members 10 slidable in guides 10a and carrying the brake members 17. In a modification, Fig. 3, the brake members 17 are carried by slides 27 connected to the bearing blocks 23 by links 29, levers 21 and links 26a, and adjustment of the spring 14 is effected by a screw 30. The springs 14 may be replaced by counter-weighted means for supporting the bearings.
