Abstract

22,467. Yardley, C. E. Oct. 3. Hooks, automatic-release.-A releasing-hook for detaching a pit cage from the hoisting- cable in the event of over-winding comprises a pair of dogs 6, 7 held together normally by a spring P and disengaged from the head M by the outer ends of the dogs engaging fixed obstructions 8, 9. The dogs 6, 7 are pivoted within a hollow casting L suspended from the hoisting-cable by a pin 10, and the head M is coupled by links N, 0 to levers A by which safety grips for suspending the cage on the guides are operated.
