Abstract

174,919. Kuffel, D. C. Feb. 3, 1921, [Convention date]. Hooks, safety.-A safety hook for use in attaching buckets &c. to hoisting cables, comprises a primary hook member 11 and a secondary hook member 2. The secondary hook is pivoted about a pin 5 within a slot in the primary and can slide in the direction of a slot 11 under the action of a spring 22. Each hook member is doubleended and has oppositely-disposed points to those of the corresponding member, which are so shaped as to allow space for connecting links 20, 21 when the combined hook is closed. In the closed or lifting position, the link 20 bears against the face of a tapering point 25, so that the links cannot be removed without sliding the member 2 relative to the member 1 against the action of the spring 22. This can only be done when there is no load.
