Abstract
410,921. Catch-gear for mine cages. BUCKNALL, A., Glenmaye, Crescent Gardens, Swanley, Kent. Feb. 2, 1933. No. 3200. [Class 78 (iii).] On breakage of the winding rope, spring actuated levers 11, 16 on the cage operate rack rods 7 in housings 17 so as to rotate spur wheels 8 and turn eccentrically mounted gripping rollers 22 into engagement with the rope guides 6. The pair of levers 11, 16 are drawn down by springs 12, 15 which are connected by a compensating rope 13 passing round a sheave 14. The four guide ropes 6 pass through housings 17 at the corners of the cage, and the two pairs of levers 11, 16 at opposite sides of the cage are connected to the lifting shackle 4 by a yoke 19 and two arched members 18 which span the width of the cage. The yoke 19 is connected with the shackle 4 by a spring 20. The levers 11, 16 engage between rollers 9 on the rack rods.
