Abstract
A quick releasable clamp for welder's ground and rod connections, characterized by a thumb operable release lever releasing an adjustable toggle link, wherein the opposed jaws have toothed engagement buried into a work piece clamped by extended lever arms having resilience for reserved clamping energy, and alternately wherein the opposed arms have wedging action to position a rod normal to the disposition of the clamp, and wherein the cable conductor is anchored remote from its terminal electrical fitting to the frame of the clamp.
Claims20
A quick releasable welder's clamp for mechanical engagement onto and electrical continuity into a work piece or rod, and including;
- an elongated frame disposed about a transverse pivot and axis and comprised of a handle portion extending rearwardly and a lever arm extending forwardly,
- an actuating lever carried by the pivot and extending rearwardly therefrom and complementary to and underlying the handle portion of the frame and from which a lever arm extends forwardly and complementry to and underlying the lever arm of the frame,
- a toggle link adapted to be releasably set by adjustment means in an adjusted over-center position and operable between the handle portion of the frame and the actuating lever to force the two arms into spaced relationship,
- a release lever carried by a pivot on the actuating lever and having a lever arm extending forwardly with a pad at the exterior of the frame for manual depression and having a lever arm extending rearwardly and engageable beneath the toggle link to lift the same from said over-center position,
- and opposed jaws carried by the complementary lever arms at the ends thereof remote from the pivot and axis for pressured engagement with opposite sides of a work piece or rod placed therebetween,
- there being an anchor coupling means mechanically and electrically connecting an electric cable to the frame.
