Abstract

A spring loaded clamp having handle members each with integrally formed cooperating jaw members, each provided with an angularly positioned, hardened steel, pointed pin adjustable anchored in the ends of the jaws with the pin points extending inwardly and abutting each other. The two handles and jaws are identical castings to cut down costs of manufacture. Each handle member is provided with inwardly extending ears pivotedly anchored together and provided with a strong torsion spring.

Claims

1. A grounding clamp of the class described comprising a pair of identical handle members, each handle member having a jaw member on one end and a pair of laterally and inwardly extending ears, the distance between each pair of ears being identical, one pair of said ears arranged to overlap the other pair Of ears, said pairs of ears having aligned apertures, means pivotally securing said ears together, each of said handles having an elongated cutout, a helical compression spring wound around said means interiorally of said ears and having the ends of said spring extending rearwardly in said cut-outs, the ends of said spring being bent substantially at right angles laterally outwardly with the terminal ends of said spring abutting against the inner surface of said handle, said jaw bored and threaded downwardly and inwardly toward said pairs of ears receiving an elongated case-hardened set screw, the inward ends of said set screws being pointed and the points abutting each other when in place in said jaws, the individual centerlines of said set screws intersecting at an acute angle, whereby when said handles are compressed towards each other the set screws will tend to approach a common center line.

2. the jaws device of claim 1 wherein the set screws are positioned in said jaws, when said device is inoperative, so that the individual center lines intersect midway between thejaws with an angle of about 15* between them and means on said set screws to prevent displacement thereof after setting.
