Abstract

16,783. Dutton, J. H. July 21. Hooks, safety.-A hook, for cranes and other purposes, of the kind having an arm projecting from the shank towards the hook proper, has a closing-latch E pivoted on the arm D with a recess I in its rounded end, into which a sliding block H enters and locks the latch E. The block is pressed by a spring in a cavity bored in the arm D, and for convenience in boring this cavity the direction of the arm D is such as to lie clear of the hook. A depression L in the latch E fits over the end of the hook.
