ABSTRACT:
An adjustable hand tool comprising an integral multi-sized socket tool, including a drive handle, and a multi-tiered drive mountable to said drive handle, said multi-tiered drives providing either a series of tiers of drives all extending concentrically from one end of the drive, or said drives being provided to either end of the tool, and capable of being shifted within the drive to provide for a drive of one dimension upon one of its ends, and a drive of a different dimension upon the opposite end, and said tiered drives being shiftable within the multi-tiered drive to provide for exposure at either end. The various drives may be of rounded shape, so as to function in a manner similar to a universal joint, while the handle is manipulated for turning of its drive, as when used for tightening or loosening a bolt. The ratchet portion of the drive may include locking means, so as to lock the ratchet head and socket relative to its handle, once adjusted into an operative position.
