ABSTRACT:
A socket wrench tool set. A hollow drive ring is retained in an annular head of a socket wrench and is rotatable therein in both directions. The wheel has a ratcheted outer peripheral portion and an interior female drive ring portion with a prismatic driving inner periphery at one end and a circular cylindrical inner periphery at the other end joined by a flat shelf. The cylindrical inner periphery has a diameter greater than that of the largest bolt with which the wrench is to be used. A ratchet pawl is mounted on the handle for engagement with the ratcheted outer peripheral portion. A series of removable sockets is provided; each has at one end a prismatic outer periphery sized for fitting in the drive ring; an inner prismatic periphery at the other end drives a nut or bolt head, and a large circular cylindrical opening, nearly as large as the distance between the opposing walls of that inner prism, extends therethrough to enable passage of a bolt all the way therethrough. Acting as a stop against which the drive end of the socket pushes. A narrow shelf joins the prismatic inner periphery to this cylindrical opening, a socket retainer in the drive ring retains an installed socket in place while enabling its ready purposeful removal.
