Abstract
632,066. Safety catch gear for hoists, lifts &c. WARRY, R. F. Jan. 24, 1948, No. 2217. [Class 78 (iii)] On breakage of its hoisting rope a platform hoist, lift cage or the like is brought to rest by a pivoted gripper bar 19 which is wedged across the guides 9, 10. The hoist which may be similar to that disclosed in Specification 627,571 comprises a platform 1 secured to a pair of uprights 2, 3 braced by members 5, 6 and 7 and carrying guide engaging rollers 8. A hoisting .cable passes around a pulley 12 secured to one end of a rod 13 which is guided for vertical movement in members 5 and 6 and carries at its other end a bar 15 which normally abuts against, and lies parallel with, the gripper bar 19. This latter bar is freely pivoted about a pin 241 on the member 5 and abuts against a stop member 24 secured to the upright 2. Springs 16, 17, which connect the gripper bar and the bar 15 respectively to the paltform 1, are normally in tension but on breakage of the cable they separate the bars 15, 19 and engage abutments 21, 22 on the bar 19, with the guides 9 and 10. Subsequent falling of the hoist engages the stop member 24 with one end of the bar 19 so forcing the abutments 21, 22 to bite into the guides.
