ABSTRACT:
An improved locking device of the hook and transverse pin type is disclosed for locking together a pair of components, characterized by the provision of a cam member that is displaceable by linearly operable cam operating means to operate a hook member between locked, safety and fully released positions relative to a locking pin member. In one embodiment, the cam member is linearly displaceable throughout its entire length of travel between locking, safety and releasing positions by the cam operating means, and in a second embodiment, the cam member is pivotally displaceable between the locking and safety positions, and linearly displaceable between the safety and releasing positions. A pawl device may be provided for normally locking the cam member in its releasing position when the pin and hook housings are separated, said pawl device being operable to its unlocked condition when the pin and hook housings are returned to their adjacent contiguous position.
