ABSTRACT:
A fixture for forming electrical connections to rail and the like includes a narrow elongated template plate operative to be positioned on and secured to a rail, and to locate an electrical connection with respect to the rail. The fixture has a parallel clamp plate spaced from the template plate forming an opening between the plates. A toggle on the clamp plate is connected to a plunger. The toggle when locked positions the plunger to enable a refractory mold to be positioned against the electrical connection, and when open permits a spring to press the plunger to press the mold against the connection, and the connection in turn against the rail. The fixture has two permanent magnets, one at each end of the template plate, which can quickly be released by applying a force to the top of the fixture from the side.
