Abstract
Abstract A ratchet and speed wrench is provided together with a set of implements comprising sockets and/or screwdriver bits and an optionally usable, upstanding speed handle. A reversible, rotatively mounted, ratchet wheel is completely contained in a ratchet handle or arm, except for a noncircular, lower projection onto which implements may be selectively fitted. The portion of the ratchet wheel within the arm has formed in its upper surface a recess (standard for the set) which is complementary in size, shape and depth to the wheel projection. The upstanding speed handle is adapted to be detachably fitted into the recess of the wheel in axial alignment with the wheel for directly turning the ratchet wheel relative to the ratchet handle. Extension bars may be interposed between the ratchet wheel and the speed handle, and/or between the ratchet wheel and the chosen implement, each bar being provided at its opposite ends with a recess and a projection of the size and shape which is standard for the set.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
212 words
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.
Claim 2
Dependent Claim
212 words
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.
Claim 3
Dependent Claim
99 words
A combination of ratchet wrench as set forth in claim 1 and speed handle which further includes c. a speed handle having as an integral part thereof a fixed, axially extending projection constructed and arranged to fit detachably but rigidly into the recess of the ratchet wheel, the construction and arrangement being such that the ratchet handle and the speed handle may be simultaneously connected and selectively operated to drive the active implement through the wheel, but the speed handle may be withdrawn at any time desired without impairing the driving connection of the ratchet handle through the wheel.
Claim 4
Dependent Claim
70 words
A combination of ratchet wrench and speed handle as set forth in claim 2 which further includes a plurality of extension bars each having at its opposite ends a socket and a projection corresponding, respectively, in size, shape and depth to the socket and the projection of the ratchet wheel, for optional use between the speed handle and the ratchet wheel and/or between the ratchet wheel and the active implement.
