ABSTRACT:
An alignment sleeve for use with an universal joint-type socket wrench which provides for self-alignment of the wrench with the nut or bolt to be turned. The sleeve includes an integral piece of highly resilient rubber molded into a hollow cylindrical shape and sized to fit snugly around the main body of the universal joint. At least one pair of semi-elliptical shaped ribs are molded into the inner surface of the opposed walls of the sleeve and adapted to interlock with the base member of the universal joint. The self-locking ribs eliminate the need for additional securing means such as clamps or adhesive. Thus, the sleeve may be installed and removed without the use of any other tools. In addition, the upper rim of the sleeve is provided with means to prevent pinching of the sleeve between the universal joint and socket where the sleeve is slightly longer than the body of the universal joint to which it is applied. This permits the sleeve to adapt to many different brands of universal joints and provide self-alignment in existing, non-aligning universal joint socket wrenches.
