Abstract: An improved holder for a carbon arc electrode has a tubular handle that receives an electrical conductor and a hose for conducting air under pressure. An insulation block is affixed to the forward end of the tubular handle. A metal torch body extends from the insulation block in the direction opposite the handle and is in electrical communication with the electrical conductor. A flow passageway opening is provided within the body. An electrode support is affixed to the body and has a concave electrode contacting surface that is inclined at an angle to the torch body and has a lower surface having a gas passageway recess therein communicating with the torch body flow passageway. A U-shaped bail extends from the insulation block and has a bight portion positioned laterally above the electrode contacting surface.

Abstract: An apparatus for carbon arc electrodes which permits the use of short length electrodes, having a body member for connection to an electrical energy source so that the body member may be manually manipulated for electric arc application purposes, and provision at the other end to removably receive a short length of electrode, the body member providing electrical continuity between the short electrode and the electrical energy source so that the short electrode may be consumed and replaced.

Abstract: A holder for an arc-forming electrode which directs the flow of air in the direction toward the arc formed by the electrode, the holder being formed of an elongated metallic body having an air supply hose and an electrical conductor attached to it, the body also having a cylindrical nozzle head rotatably affixed at the forward end, the turret having an upper surface with a notch formed therein to receive an electrode, the nozzle head having an internal passageway and a cylindrical external sidewall having an air jet opening communicating with the passageway and arranged to eject air in alignment with the notch, the body having a passageway therein communicating air supplied by the hose to the nozzle head and a tong member pivotally affixed to the body having a spring for releaseably retaining an electrode in contact with the notched upper surface of the nozzle head.

Abstract: A torch for a carbon electrode, the torch having a body with a conductive electrode support affixed to the forward end and means at the rearward end for attachment of a voltage source and air pressure, the body and electrode having a passageway for ejection of air forwardly of and along the electrode, a pair of elongated paralleled bail members extending from the body and to either side of the electrode support and an electrode engagement member secured between the outer ends of the bail members, the carbon electrode being receivable between the electrode engagement member and the electrode support, the bail members being deflected towards the electrode support thereby retaining the electrode in selected positions and wherein the user positions the carbon electrode by deflecting the bail members rearwardly relative to the electrode support.

Abstract: A holder for a cylindrical carbon arc electrode, comprising an elongated body of selected metal, having a forward and a rearward end, and a tubular handle attached to the bottom surface, at a selected angle. The top surface of the body has a longitudinal groove adapted to receive a cylindrical electrode and hold it co-linear with the top surface of the body. A quick-acting toggle clamp or latch means is provided, so that by simply pivoting a wire lever the latch can be loosened, and the position of the electrode in the groove can be altered. Various shapes and constructions can be provided, and the bail of the clamp can press directly on the electrode, or through means of metal blocks, etc.

Abstract: A holder for a carbon arc electrode: the holder having an elongated body with an opening therethrough in which the electrode is positioned, the body having a slot in the lower end thereof communicating with the opening, the opening being defined in cross-section such that the portion adjacent the slot provides opposed uniplanar ledges to either side of the slot, the plane of the ledges being tapered relative to the axis of the opening through the body; a slide block of length less than the body, the slide block being configured to be slidably positioned in the opening in the body, the bottom of the slide block being an engagement with the ledges, slide block having an electrode engaging upper surface which has a taper of the same angle as the taper of the ledges, the taper being oppositely inclined to that of the ledges so that the electrode engaging surface is parallel to the axis of the opening through the body so that the electrode is contacted by increased pressure as the slide block moves forwardly in th
