Abstract
A tool locking and releasing device having a rotatably driven spindle rotatably mounted on a support frame. A socket is formed in the spindle coaxial with an axis of rotation thereof and is adapted to receive a tool holder and to retain it against relative rotational movement. Wrench means is provided to grip a tool locking member so that upon the application of a rotary drive to the spindle in a first directional sense the tool holder is rotated and the tool locking member is tightened with a predetermined torque, and upon the rotation of the spindle in an opposite directional sense the tool locking member is loosened.
