Abstract

Abstract A combination open end wrench and ratcheting wrench for a hexagonal member, the wrench having a body and a handle extending in one direction and opposed, spaced apart jaws extending in the opposite direction, one of the jaws being a torqueing jaw and the other being a back up jaw, the back up jaw having a planar working surface, the torqueing jaw having a breaking surface adjacent the body and parallel to the back up jaw, the torqueing jaw having an arcuate surface adjacent the breaking surface and the torqueing jaw having a ratcheting surface adjacent the arcuate surface, the ratcheting surface being parallel the back up working surface, the ratchet surface being in length less than one half the length along one side of the hexagonal member to which the wrench is dimensioned to fit, and the torqueing jaw having a retaining surface intersecting the ratcheting surface at an angle of 120 degrees.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 235 words
A combination open end wrench and ratcheting wrench for a hexagonal member wherein the member has a width across opposing corners of A, a width across opposing sides of B, and a length along one side of C, the wrench comprising: a wrench body portion having a handle portion extending in one direction therefrom and opposed, spaced apart jaws extending in the opposite direction, one of the jaws being a torqueing jaw and the other being a backup jaw, the backup jaw having a planar working surface facing the torqueing jaw, the torqueing jaw having: 1. a breaking surface adjacent the body portion parallel the backup jaw and spaced from the backup jaw a distance slightly greater than B, the length of the breaking surface being greater than 1/2 C, 2. an arcuate surface adjacent said breaking surface, the distance of the arcuate surface from said backup jaw working surface as measured perpendicular the working surface being greater than A, 3. a ratcheting surface adjacent said arcuate surface, the ratcheting surface being parallel to said backup jaw working surface and spaced from it a distance slightly greater than B, the length of the ratcheting surface being less than 1/2 C, and 4. a retaining surface intersecting said ratcheting surface at an angle of 120* , the plane of the retaining surface intersecting the plane of backup jaw working surface at an angle of 60* .
Claim 2
Dependent Claim 235 words
A combination open end wrench and ratcheting wrench for a hexagonal member wherein the member has a width across opposing corners of A, a width across opposing sides of B, and a length along one side of C, the wrench comprising: a wrench body portion having a handle portion extending in one direction therefrom and opposed, spaced apart jaws extending in the opposite direction, one of the jaws being a torqueing jaw and the other being a backup jaw, the backup jaw having a planar working surface facing the torqueing jaw, the torqueing jaw having: 1. a breaking surface adjacent the body portion parallel the backup jaw and spaced from the backup jaw a distance slightly greater than B, the length of the breaking surface being greater than 1/2 C, 2. an arcuate surface adjacent said breaking surface, the distance of the arcuate surface from said backup jaw working surface as measured perpendicular the working surface being greater than A, 3. a ratcheting surface adjacent said arcuate surface, the ratcheting surface being parallel to said backup jaw working surface and spaced from it a distance slightly greater than B, the length of the ratcheting surface being less than 1/2 C, and 4. a retaining surface intersecting said ratcheting surface at an angle of 120* , the plane of the retaining surface intersecting the plane of backup jaw working surface at an angle of 60* .
Claim 3
Dependent Claim 29 words
an arcuate surface adjacent said breaking surface, the distance of the arcuate surface from said backup jaw working surface as measured perpendicular the working surface being greater than A,
Claim 4
Dependent Claim 29 words
an arcuate surface adjacent said breaking surface, the distance of the arcuate surface from said backup jaw working surface as measured perpendicular the working surface being greater than A,
Claim 5
Dependent Claim 65 words
A wrench according to claim 1 wherein said torqueing jaw has a positioning surface at the wrench body portion intersecting said breaking surface at an angle of 120* , and wherein said backup jaw includes a positioning surface at the wrench body intersecting said working surface at an angle of 120* , the two positioning surfaces intersecting each other at an angle of 120* .
Claim 6
Dependent Claim 49 words
A wrench according to claim 1 wherein said torqueing jaw breaking surface includes a plurality of paralleled grooves therein perpendicular the length of the torqueing jaw, the grooves forming teeth in the breaking surface which serve to more effectively engage a hexagonal member to be rotated by the wrench.
Claim 7
Dependent Claim 40 words
a ratcheting surface adjacent said arcuate surface, the ratcheting surface being parallel to said backup jaw working surface and spaced from it a distance slightly greater than B, the length of the ratcheting surface being less than 1/2 C, and
Claim 8
Dependent Claim 40 words
a ratcheting surface adjacent said arcuate surface, the ratcheting surface being parallel to said backup jaw working surface and spaced from it a distance slightly greater than B, the length of the ratcheting surface being less than 1/2 C, and
Claim 9
Dependent Claim 33 words
a retaining surface intersecting said ratcheting surface at an angle of 120* , the plane of the retaining surface intersecting the plane of backup jaw working surface at an angle of 60* .
Claim 10
Dependent Claim 33 words
a retaining surface intersecting said ratcheting surface at an angle of 120* , the plane of the retaining surface intersecting the plane of backup jaw working surface at an angle of 60* .
Claim 11
Dependent Claim 72 words
A wrench according to claim 3 wherein the plane of the torqueing jaw breaking surface is inclined towards the plane of the backup jaw working surface, the spacing between said backup jaw working surface and said torqueing jaw breaking surface at one edge thereof being less than B, whereby the breaking surface and the opposed backup jaw working surface may be forced to securely engage the opposite sides of a hexagonal member.
Claim 12
Dependent Claim 33 words
A wrench according to claim 1 wherein said torqueing jaw and said back up jaw are closed to each other at the outer ends whereby the wrench is of a box end configuration.
