Abstract
Abstract A clamp for fastening an object to a supporting bar has a body forming a first clamp jaw and carries a swingable arm forming a confronting second clamp jaw; the free end of the arm is bifurcated and engageable by a thumb nut on a bolt also articulated to the body. The pivot of the arm is slidable in an inclined track diverging at a small angle, in the direction toward the body, from the line of force exerted by the engaged thumb nut upon the free end of the arm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
A clamp for fastening a load to a bar-shaped support, comprising: a body provided with a face having a first groove engageable with a lateral surface of the support; coupling means on said body for joining same to the load; an arm pivotally secured at one end thereof to said body on one side of said first groove and provided with a portion spacedly overhanging said face, said arm being formed at said portion with a second groove confronting said first groove, said body forming a track for the pivot of said one end diverging at a small angle from a plane of symmetry of said first groove, perpendicular to said face, in a direction away from said face whereby said pivot is shifted away from said plane of symmetry upon a displacement of said portion toward said face; and latch means articulated to said body at the opposite side of said first groove for engagement with said arm, the latter having a free other end beyond said portion engageable by said latch means for maintaining said portion substantially parallel to said face in an operative position to hold said support gripped between said grooves.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
14 words
A clamp as defined in claim 1 wherein said grooves are of polygonal cross-sections.
Claim 4
Dependent Claim
13 words
A clamp as defined in claim 2 wherein said cross-sections are substantially trapezoidal.
Claim 5
Dependent Claim
40 words
A clamp as defined in claim 1 wherein said other end of said arm forms a pair of parallel prongs, said latch means including a bolt receivable between said prongs and a nut on said bolT tightenable against said prongs.
Claim 6
Dependent Claim
46 words
A clamp as defined in claim 4 wherein said other end is provided with an outer circular depression of a diameter greater than the spacing of said prongs, said nut having a neck fitting into said depression for preventing disengagement of said bolt from said prongs.
Claim 7
Dependent Claim
63 words
A clamp as defined in claim 1 wherein said body has a recess extending inwardly from said face, said recess being bounded by sides lying parallel to the pivotal plane of said arm and receiving said one end thereof between them, said track being formed by a pair of slots in said sides slidably accommodating a pair of projections on said one end.
Claim 8
Dependent Claim
13 words
A clamp as defined in claim 1 wherein said arm is generally elbow-shaped.
