ABSTRACT:
A universal joint adapted for attachment to a socket wrench or similar device. The universal joint includes first and second bodies having adjacent convexly curved outer surfaces. Each body has a central axis, and the curved surface on each body defines a pole along the corresponding central axis. A plurality of angularly spaced teeth are provided on the curved surface of each body and extend from the pole thereon to a position along the side of the corresponding body. The teeth are adapted for meshing engagement regardless of the relative angular displacement between the central axes of the bodies. Each body defines a cavity therein and a hole extending from each cavity to the corresponding pole. A reciprocating plate is positioned in each cavity, and a flexible cable or wire interconnects the plates. Springs are positioned around the cables in the cavities for biasing the plates apart. In an alternate embodiment, an O-ring is provided as a bushing adjacent the pole of each body for guiding the wire and for minimizing wear on the wire and reducing the likelihood of binding during mutual rotation of the bodies.
