Abstract

333,080. Coates, H. Sept. 16, 1929. Catch gear and like safety retaining-mechanism. -When the hoisting rope breaks the lower portions of the wedges 1 are pressed against the guides 2 by spring-operated tee-shaped levers 4 acting through links 3, whereby the wedges are arrested relatively to the cage, thus causing the bearings 7 to engage the upper portions of the wedges and stop the cage. In normal operation the retaining mechanism is held out of action through rods 15, links 13 sliding in guides 14, and links 13 connected to the tee-levers 4.
