Abstract

13,427. Adams, F. E. June 6. Catch gear of mine-cage type.-Safety suspending-apparatus for colliery cages and lifts comprises loops d bent around the four guideropes h and supporting gripping - cams a mounted within the loop on transverse shafts g. The loops d are connected in pairs by bars c, and are attached to the cage roof by brackets e. Curved levers b mounted centrally on the shafts g are connected by a link a<2> to the hoisting- ring f<2>. If the hoisting-cable breaks, weights f tilt the levers b and bring the cams a into engagement with the guides h.
