Abstract
Abstract An electrical conduit grounding device includes a clamp formed of a pair of similarly shaped screw connected clamp sections each formed of a web including a crowned medial section terminating in coplanar wings and provided with longitudinal flanges. One of the clamp sections is provided with a cable clamp at the crown apex and which is stamped and shaped from the web, leaving corresponding openings therein, and includes first and second laterally spaced vertical arms atop the crowned section, a longer arm terminating in a horizontal leg projecting toward and above the top of the other arm. The leg has a tapped vertical bore engaged by a cable clamping screw.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A conduit grounding device comprising a pair of first and second conduit clamp members relatively movable between an open conduit release and a closed conduit clamping position and delineating a clamp engaging longitudinal passageway, said first clamp member including a laterally extending web having stamped therefrom to leave a corresponding first opening therein, an outwardly extending first leg terminating in a raised laterally projecting arm directly overlying a predetermined portion of said web and having a tapped vertically extending bore therein and said first clamp member laterally extending web having stamped therefrom to leave a corresponding second opening therein laterally spaced from said first opening an outwardly extending second leg having a free end transversely spaced from the free end of said arm, and a screw engaging said tapped bore and adapted to clamp a cable between said screw and said predetermined web portion, said first and second legs and said arm delineating a second longitudinal passageway and the proximate edges of said arm and second leg delineating a lateral passageway into said second longitudinal passageway.
Claim 2
Dependent Claim
176 words
A conduit grounding device comprising a pair of first and second conduit clamp members relatively movable between an open conduit release and a closed conduit clamping position and delineating a clamp engaging longitudinal passageway, said first clamp member including a laterally extending web having stamped therefrom to leave a corresponding first opening therein, an outwardly extending first leg terminating in a raised laterally projecting arm directly overlying a predetermined portion of said web and having a tapped vertically extending bore therein and said first clamp member laterally extending web having stamped therefrom to leave a corresponding second opening therein laterally spaced from said first opening an outwardly extending second leg having a free end transversely spaced from the free end of said arm, and a screw engaging said tapped bore and adapted to clamp a cable between said screw and said predetermined web portion, said first and second legs and said arm delineating a second longitudinal passageway and the proximate edges of said arm and second leg delineating a lateral passageway into said second longitudinal passageway.
Claim 3
Dependent Claim
43 words
The conduit grounding device of claim 1 wherein said web includes upwardly converging laterally spaced side sections and a horizontally extending top section extending between the upper ends of said side sections, said first and second openings being formed in said side sections.
Claim 4
Dependent Claim
22 words
The conduit grounding device of claim 2 wherein said top section faces and is spaced from said bore in said projecting arm.
Claim 5
Dependent Claim
23 words
The conduit grounding device of claim 2 including coplanar laterally outwardly projecting wings extending from the lower edges of said web side sections.
Claim 6
Dependent Claim
23 words
The conduit grounding device of claim 4 including vertically projecting flanges formed along the longitudinal edges of said web side sections and wings.
Claim 7
Dependent Claim
67 words
The conduit grounding device of claim 4 wherein said second clamp member comprises a web including downwardly converging laterally spaced side sections, a horizontally extending top section extending between the bottom ends of said second clamp side sections and terminating in horizontal coplanar wings confronting the underfaces of said first clamp member wings and comprising screws extending between and engaging the wings of respective confronting pairs thereof.
