Abstract
An electrode holder to be connected to a welding current cable and having a pair of jaw support members pivoted to a tubular member therebetween which has a bore receiving said cable, the cable being connected by separate conductors to electrode gripping jaw pieces in said support members, and a pair of springs separately urging the respective jaw support members about said pivot to bring the jaw pieces together and clamp an electrode therebetween, the ends of the springs being supported in a collar which surrounds the tubular member and is adjustable longitudinally thereof to adjust the spring pressure closing said jaw pieces.
Claims9
A holder for supporting a welding electrode and connecting it to a current carrying cable entering the holder, comprising:
- a. an externally threaded tubular member having an axial bore therethrough receiving said cable at one end and having a transversely disposed pivot at the other end;
- b. a pair of jaw support members disposed on opposite sides of said tubular member and each connected intermediate its ends with said pivot, each of the support members having a handle portion at one end overlying the tubular member and having at its other end a jaw portion extending beyond the pivot and having electrode gripping means, the electrode gripping means on the jaw support portions of the paired support members being mutually opposed;
- c. a spring holding collar surrounding the tubular member and axially positionable thereon beneath said handle portions, the collar having spring locating means facing outwardly toward each handle portion, and the handle portions of the jaw support members each having a spring locating means facing toward said collar;
- d. a pair of springs mounted in said spring locating means and each extending between the collar and a different one of said handle portions, thereby urging the handle portions apart and the jaw portions together, the springs and locating means being located at about the same distance from the pivot as the electrode gripping means of the jaw portions and on the other side of the pivot therefrom;
- e. conductor means joining said electrode gripping means to said cable;
- and
- f. sleeve means threadedly engaging said tubular member and abutting said collar, and operative to adjust the compression of said springs when the sleeve means is screwed axially back and forth on the tubular member.
