Ratcheting wrench for octagonal members

Claim 1

A ratcheting wrench for an octagonal and a hexagonal member, the width across opposite corners of the octagonal member being designated by B, the width across opposite sides of the member being designated by A, and the length along a side of the member by D, the wrench comprising: a body; a handle means attached to the body; two spaced apart, parallel jaws designated a torquering jaw and a backup jaw, the jaws extending from the wrench body in the direction opposite the handle means, the backup jaw having a planar working surface facing the torqueing jaw, the torqueing jaw having a working surface, facing the backup jaw working surface the torqueing jaw working surface being in the form of a projecting tooth, the distance between said backup and torqueing jaw working surfaces being slightly greater than A, and the body having member engaging working surfaces between the backup jaw and torqueing jaw working surfaces defined by: a. a first body working surface of length slightly greater than D intersecting said backup jaw working surface at an angle of 45*, b. a second body working surface of length less than D intersecting said first body working surface at an angle of 45*, the plane of the second body working surface being perpendicular to the plane of said backup jaw working surface, and c. a third body working surface of length slightly greater than D and at a 45* angle with respect to said second body working surface, said torqueing jaw terminating at the outer end thereof opposite said handle in an inclined slipping surface adjacent said torqueing jaw working surface, the plane of the inclined slipping surface intersecting the plane of said backup jaw working surface at an acute angle and in the direction of said handle, said torQueing jaw working surface having a recess therein formed by the intersection of said third body working surface and said projecting tooth, the distance between said backup jaw working surface and said recess being greater than A, said first body working surface having a first V-shaped notch formed therein adjacent the intersection of said first body working surface with said second body working surface and a second V-shaped notch formed at the end of said second body working surface opposite said first body working surface, said third body working surface forming one side of said second Vshaped notch, said recess in said torqueing jaw working surface, said first and second V-shaped notches, and said backup jaw working surface engaging a hexagonal member.
