ABSTRACT:
A socket wrench of improved design which not only provides for interchangeability but also for easy removal of the socket member. The ratchet and socket openings are provided in separate annular coaxial members. The ratchet wheel is adapted to loosely receive a removable socket insert. The periphery of the ratchet wheel is provided with a plurality of ball bearings which are mounted in openings which face inwardly toward the socket insert. The socket insert is provided with receiving structure for the ball bearings. A spring wraps around a portion of the periphery of the ratchet wheel and normally biases the ball bearings into locking engagement with the socket insert. The spring is provided with a portion spaced from the ratchet wheel which is actuatable to release the spring tension on the ball bearings, thus permitting the socket insert to freely drop out of the ratchet wheel.
