Patent for a new and improved electric-arc lamp. This design consists in "the combination of a single horseshoe electro-magnet in the circuit of a main line, connected on the positive side to a binding-post having shunt material as a bushing around it, an armature hinged at its center and free to vibrate throughout its length with a carbon-rod holder, which it is adapted to clutch at the hinged part, said magnet acting upon the ends of the armature only, and an adjustable trip and limiting-stops, and means permitting both to be readily adjusted upon the outside of the casing to regulate the lamp" (lines 46-58).
