The principle of this invention consists chiefly in con- structing electric lamps made luminous by incandescence, as well as by the voltaic arc; by means of continuous or alternating currents which produce the incandescence of a thin rod (preferably of carbon) and a voltaic arc at the circumference of a rod of refractory material, which may be fixed or movable on the second electrode o£ large section. One model showing inventions and improvements in electric lighting and apparatus therefor. The improvements consist in illuminating a flame of gas by passing therein and thereby an electric current, so that the passage of the current in the flame excites and transforms into luminous vibrations certain undulations of the gas-flame. The invention consists in the use of materials, relatively slight conductoi’S of electricity, in a finely divided state, such as powdered coal and magnetizable metals, or carbon and combustible gases (simple or compound), or steam or liquids in a globular form. Also in the double mode of feeding the lamp. Southern Gallery. 422 .—White House Mills, Hoosac, New York. Agents, Jas. S. Mackie & Son, 194, Broadway, New York. Arc Lamps, Ball's system.
