ABSTRACT:
This invention is directed to rotary release hook apparatus comprising a rotatable release hook of a generally circular configuration. In the release hook there is a recess for receiving a cable or a rope or a chain. The rotary release hook apparatus can be on a dock or an oil well platform or a barge or another suitable device. The cable or rope or chain cam connect with a boat or a ship or a barge or other large similar object. In the release hook there is a notch. There is a rotatable pawl having a projecting finger projecting into the notch to prevent rotation of the release hook. There is a rotatable member having a recess. Part of the pawl bears against the rotatable member. There is a release lever arm connecting with the rotatable means for rotating the rotatable member to allow the pawl to move into the recess and away from the rotatable release hook. This allows the rotatable release hook to rotate to release the cable or rope or chain. Further, there is a locking member to restrict the movement of the release lever arm and thereby to restrict the rotation of the rotatable members and thereby to restrict the rotation of the rotatable pawl and thereby to restrict the rotation of the rotatable release hook.
