Abstract
Abstract A wrench including a handle portion and a wrench head that comprises an insertable flat disk containing an aperture therein for receiving a nut or the head of a bolt and, which further includes a rotatable drive shaft and a series of gears to provide rotation of the disk for turning the nut. The wrench is designed to be used in places where very little room is provided for turning a manual box or open-ended wrench in the necessary side-to-side motion. The wrench of the present invention including the flat nut turning disk is devoid of any protruding components such as is standard in the conventional socket wrenches.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
A wrench containing an elongated handle and a head, said head comprising a rotatable flat disk containing an aperture therein for engaging a nut or bolt head, a housing enclosing the rotatable disk for rotation thereof relative to the housing, a gear disk connecting with said rotatable disk within the housing and containing gear teeth about a periphery thereof, an elongated drive shaft positioned through said handle and terminating at one end at a point beyond said handle to be engaged by a rotating means and terminating at another end in a rotatable gear drive means containing gear teeth which intermesh with said gear teeth on said gear disk, said gear drive means being rotatable about a longitudinal axis of said handle and about a line perpendicular to a rotating axis of said gear disk with its connecting rotatable disk, said gear disk with its connecting rotatable disk being of circular shape having the gear teeth of said gear disk being contained within a uniform strip forming the circumference of said gear disk, said gear disk including a circular plate positioned within the circumference of said gear teeth, said plate containing a plurality of apertures, said rotatable disk including a plurality of posts positioned thereon to match the positions of said apertures on said plate, said rotatable disk being secured to said gear disk by the insertion of said posts in said apertures.
Claim 2
Dependent Claim
233 words
A wrench containing an elongated handle and a head, said head comprising a rotatable flat disk containing an aperture therein for engaging a nut or bolt head, a housing enclosing the rotatable disk for rotation thereof relative to the housing, a gear disk connecting with said rotatable disk within the housing and containing gear teeth about a periphery thereof, an elongated drive shaft positioned through said handle and terminating at one end at a point beyond said handle to be engaged by a rotating means and terminating at another end in a rotatable gear drive means containing gear teeth which intermesh with said gear teeth on said gear disk, said gear drive means being rotatable about a longitudinal axis of said handle and about a line perpendicular to a rotating axis of said gear disk with its connecting rotatable disk, said gear disk with its connecting rotatable disk being of circular shape having the gear teeth of said gear disk being contained within a uniform strip forming the circumference of said gear disk, said gear disk including a circular plate positioned within the circumference of said gear teeth, said plate containing a plurality of apertures, said rotatable disk including a plurality of posts positioned thereon to match the positions of said apertures on said plate, said rotatable disk being secured to said gear disk by the insertion of said posts in said apertures.
