Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
173 words
A tubular socket wrench for an equilateral polygonal nut comprising a straight tube of predetermined material and length and diameter and wall thickness with the ends thereof normal to the axis of said tube and having a predetermined number of equispaced longitudinal narrow slots of predetermined length through one end portion of said tube forming a like number of fingers of substantially equal width and in equilateral polygonal formation coaxial with said tube and adapted for spring contact against the outer sides of said nut, each of said fingers formed at a small predetermined divergent angle from said tube and flattened at an outer end portion thereof with the inner corners of the ends of said fingers chamfered whereby a nut having flat outer sides equal to the number of said fingers may be manually urged into frictional contact with the inner flat sides of said fingers coaxial with said axis and temporarily manually positioning said nut coaxial with a mating threaded member and rotating said nut on said member with said wrench.
Claim 2
Dependent Claim
173 words
A tubular socket wrench for an equilateral polygonal nut comprising a straight tube of predetermined material and length and diameter and wall thickness with the ends thereof normal to the axis of said tube and having a predetermined number of equispaced longitudinal narrow slots of predetermined length through one end portion of said tube forming a like number of fingers of substantially equal width and in equilateral polygonal formation coaxial with said tube and adapted for spring contact against the outer sides of said nut, each of said fingers formed at a small predetermined divergent angle from said tube and flattened at an outer end portion thereof with the inner corners of the ends of said fingers chamfered whereby a nut having flat outer sides equal to the number of said fingers may be manually urged into frictional contact with the inner flat sides of said fingers coaxial with said axis and temporarily manually positioning said nut coaxial with a mating threaded member and rotating said nut on said member with said wrench.
Claim 3
Dependent Claim
48 words
The construction recited in claim 1 wherein said tube has six slots forming six said fingers in equilateral polygonal position and adapted to frictionally and coaxially engage the sides of a hex nut or a like size hex nipple or fitting having a like size hex projection thereon.
