Abstract

New electrode clamp, which is essentially characterized by comprising an insulating cover to electricity, and the projection of incandescent particles, which form two hollow bodies, one of external cylindrical shape, being inferiorly of partially cylindrical section, continuing in another part hollow of hexagonal section, joining said body to another body, composed of a cylinder that is transformed into a truncated cone, which is joined by its lower base another cylinder that forms its semi-hemisphere free base, and this last hollow body, in such a way that its internal sections are cylindrical and exagonal respectively; the aforesaid sheath being externally provided with fins on one part and with threadings of intersecting ribs on the other, with the purpose of being able to rotate, by means of the fins, the part that contains them, and of avoiding by filleting the other part, that the tool slips by the hand; lodging inside this sheath, metallic pieces, of which one, of cylindrical shape, and exaggerated prismatic in its extension, internally presents an eccentric drill of cylindrical section that is reduced by a base, in another blind hole, and also of cylindrical section, said piece having clamping elements threaded in its wall, which retain the cable coming from the welding group; said piece being drilled and threaded inside its hexagonal part, in such a way that by means of said thread, another part is joined to it, which transforms its threaded neck into a hexagonal prism, which has at its end two circular holes that communicate with two others, located analogously in the insulating sheath, the piece being lately described being provided with a drill of quadrangular section, in which an element is fitted, also of quadrangular section, which has one end cut in an inclined plane, forming in the other end a hemispherical head, which retains a helical spring, embracing the piece to which we alluded, is located in the unthreaded space of the axial hole that exists in the piece to which the other piece that contains the latter is threaded of quadrangular section, the latter being the one that by means of its inclined plane of one end, imprisons or releases, according to turns of the head of the cover, the electrode that is introduced through the orifice s to the effect, already mentioned.
