1. A ratchet wrench for applying and removing nuts, screws and bolts, through suitably recessed driving implements of a matched set comprising, in combination:

  • a. a leverage providing ratchet handle which includes a pair of pawls and means for making the pawls alternatively active and inactive; and

    b. a ratchet wheel, rotatively mounted in the ratchet handle, for rotation about an axes angularly related to the handle and selectively cooperative with the pawls, and having as an integral part thereof a noncircular projection that protrudes axially below the ratchet handle and is adapted to have a driving fit in any member of the matched set of recessed driving implements, the ratchet wheel being otherwise confined within the bounds of the handle body and having a noncircular recess in its upper face which is complementary in size, shape and depth to said projection, and is coaxial with the projection, the construction and arrangement being such that any drive member having a projection of the same shape and dimensions as the projection on the ratchet wheel is adapted to be applied directly to any member of the ratchet implement set to which the ratchet wheel may be applied, and may also be applied through the wheel to act upon any selected one of said implements.
