  • Patent number: 4817476
    Abstract: A locking socket wrench extension includes an elongated extension member having an axially aligned opening at one end adapted to receive the driving stud of a ratchet wrench or similar tool and including a socket drive stud at the other end thereof. A socket engaging ball which is adapted to lock a socket onto the extension stud is located in a transverse slot in the side wall of the extension stud. An elongated pin is contained within and coaxial with the extension member and is movable rearwardly and forwardly. When in the forward position, the pin moves the ball into its locking position. In one embodiment, the pin extends rearwardly into the stud opening. As the driving stud of a ratchet wrench is inserted into the opening, the pin is pushed forwardly to lock the ball in place. In another embodiment, the pin is biased forwardly in the locking position but can be moved rearwardly by manually sliding a button located on the exterior of the extension which is interconnected with the pin.
