Abstract: A portable exothermic welding ignition controller includes a housing configured to receive a first portion of a portable power tool battery with a second portion of the portable tool battery external to the housing. A circuit board is positioned within the housing and configured for electrical coupling to the portable power tool battery. An actuator is operatively engageable with the circuit board for selectively discharging power from the portable power tool battery to a connection terminal electrically coupled to the circuit board.

Abstract: The present disclosure relates to a new improved dual crimping and cutting tool, such as a portable hand tool with removable for repair or adding features having a rotating jaw serving in one area as a cutter blade against the body of the tool, and in an adjacent area a crimping portion for conducting a semi-circular crimping for one of multiple size conductors. The invention includes features such as a multi-die removable wheel, a rounded periphery multi-die removable wheel, a dual segment jaw, a multiple angle crimping nest, a new jaw with a self-release and a manual release, a high leveraged multi-groove driving pawl, and a removable blade system.

Abstract: A washer includes a perimeter portion, a support edge adjoining the perimeter portion and defining a first plane, and a contact portion having a generally planar contact surface. The contact surface defines a second plane parallel to and spaced from the first plane. The contact portion further includes at least two apertures extending therethrough. The washer further includes a rim portion extending between the perimeter portion and the contact portion. The rim portion surrounds the contact portion and forms an angle with the first plane of between 6 and 20 degrees. The contact portion and the rim portion are integrally formed as one-piece.

Abstract: An assembly is disclosed for exothermic welding comprising a mold which is formed of a material which withstands exothermic welding temperatures and includes a weld cavity therein for positioning at least two members which are to be exothermically welded together, and an ignition cavity communicating with the weld cavity. The mold is capable of accommodating any one of several exothermic welding procedures which may involve either a flint igniter or the use of an electrical igniter which is readily accommodated by the mold in the performance of several of the procedures. The electrical igniter is formed of a pair of flat, longitudinally extending conductor strips with a sheet of insulation laminated therebetween, a filament adjacent one end of the strips, and one or more positioning tabs adjacent one end of the strips. A cartridge is also provided which contains the weld metal and the electrical igniter and which may be positioned in the ignition cavity of the mold.

Abstract: An assembly and method are disclosed for exothermic welding including a mold which is formed of a material which withstands exothermic welding temperatures, and includes a weld cavity therein for positioning at least two members which are to be exothermically welded together adjacent to each other, and an ignition cavity communicating with the first cavity. The members which are to be exothermically welded together are positioned adjacent to each other using the weld cavity, and a weld metal cartridge is positioned in the ignition cavity. The cartridge comprises a container having copper walls which define a chamber therein, and a particulate weld metal in the chamber.

Abstract: A staking nut and a grounding clamp with the staking nut are disclosed in which the clamp includes a flexible metal strap with openings through the ends of the strap. Threaded studs extend through the openings at one end of the strap to firmly attach the lug of a grounding conductor to the strap. The staking nuts are provided through the openings at the other end of the strap to prevent removal of the nuts from the strap, but permit rotation so that the nuts while held captive to the strap may be threaded upon the threaded studs to clamp the grounding clamp to a coaxial cable which is to be grounded.

Abstract: Handle clamps and a clamping kit for clamping or clamping and fastening a mold during exothermic welding are disclosed in which a single handle clamp may be utilized in at least three different exothermic welding operations. The handle clamp may be utilized with or without removable support arms to simply clamp the mold parts together where only the ends of cables are to be connected together within a cavity of the mold. If it is desired to connect the cables to either a flat surface or a curved surface, the support arms are attached to the handle clamp, and either a magnetic fastening assembly or a chain assembly is attached to the support arms to fasten the handle clamp and mold to the respective differently shaped surfaces.
