Patent number: 9702395Abstract: 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.Type: GrantFiled: July 21, 2015Date of Patent: July 11, 2017Assignee: HARGER, INC.Inventors: Mark S.

Patent number: 8581149Abstract: 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.Type: GrantFiled: April 21, 2011Date of Patent: November 12, 2013Assignee: Harger, Inc.Inventors: Curtis R. Stidham, Mark S. Harger
