Abstract
A locking tool holder is disclosed which has a socket adapted to receive a tool which has a lateral recess. The tool holder contains a lock pin which is slidable in a first aperture transverse to the tool socket, and this lock pin has a wedge portion on the inboard end thereof to engage a tapered lateral recess on the tool. A cam bar is slidable transversely to the lock pin in another aperture in the tool holder, and has first and second cam surfaces to cooperate with first and second cam followers on the lock pin. The cam bar may be moved manually or by a spring into a first locked position, whereat the second cam engages the second cam follower on the lock pin to force the lock pin wedge portion against the lateral recess in the tool. When the cam bar is moved into the second position, the first cam surface engages the first cam follower on the lock pin to withdraw the lock pin from the tool so that the tool may be removed from the tool socket. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
