Abstract

732,716. Mine cage catch gear. COAL INDUSTRY (PATENTS), Ltd. Aug. 12, 1953 [Aug. 18, 1952], No. 20701/52. Class 78 (3). Catch gear for a mine cage comprises wedges 10 located in slots 15 in a slipper 11 engaging a cage guide rail or rope (not shown), and freely suspended from a lever 6 which is pivoted to the slipper at 20 and is urged clockwise by a spring 9 and a weight 8. Two such devices are provided, one for each guide, and the arrangement is such that normally ropes 7, secured to the hoisting rope (not shown), hold the devices out of action, whilst when the tension in the hoisting rope is reduced the wedges are forced into engagement with the guides and the cage is brought to rest.
