ABSTRACT:
An auxiliary handle assembly useful with load-lifting hand tools. The assembly includes a cylindrical sleeve with an external thread, the sleeve being received over the end of the primary handle before its operating member is attached thereto. An auxiliary handle is connected to the sleeve by an attachment nut which has a single turn thread which engages the external thread of the sleeve. The sleeve and primary handle turn freely relative to the attachment nut to permit dumping of the load carried by operating member. The load application point of the auxiliary handle can be moved up and down the primary handle by relative rotation between the attachment nut and the sleeve to optimize the lifting capabilities of the modified tool for a particular user.
