초록 ▼

A plurality of circumferentially-spaced driving lugs are formed on the improved square-drive tang of a wrench, such as a ratchet wrench; and these driving lugs cooperate with a corresponding plurality of recesses or pockets formed in the top portion of an improved interchangeable square-drive socket, thereby providing for improved torque transmission which is supplemental to, and not a substitute for, the square drive. The improved wrench is compatible with conventional sockets, and the improved socket is compatible with conventional wrenches.

대표청구항 ▼

[ I claim:] [1.] In combination, a modified ratchet wrench and a modified wrench socket, wherein the modified ratchet wrench may be used with a conventional socket, and wherein the modified wrench socket may be used with a conventional ratchet, comprising a drive tang on the modified ratchet wrench, the drive tang having a first portion adjacent to the modified ratchet wrench and further having a second portion extending from the first portion to the end of the drive tang, at least one supplementary driving lug carried only by the first portion of the drive tang and extending radially therefrom, such that the supplementary driving lug does not extend the full length of the drive tang, the modified wrench socket having an opening receiving the drive tang and complementary thereto to effect torque transmission therebetween, the modified wrench socket having a top portion and further having at least one internal pocket extending axially from the top portion of the modified wrench socket and radially of the opening formed therein to receive the supplementary driving lug on the drive tang of the modified ratchet wrench; such that when the modified ratchet wrench is engaged with the modified wrench socket, the drive is through both the drive tang and the supplementary driving lug on the drive tang; thereby accommodating increased leverage on the modified ratchet wrench, preventing slippage between the modified ratchet wrench and the modified wrench socket, and precluding premature failure of the drive tang; and such that when the modified ratchet wrench is engaged with a conventional socket, the drive is only through the drive tang and the supplementary driving lug extends above the conventional socket; and such that when a conventional ratchet is engaged with the modified wrench socket, the drive is only through the drive tang of the conventional ratchet, and there is no engagement with the internal pocket in the modified wrench socket.
