FLASHLIGHT WITHOUT FLAME.

Electric Lamp that Lessens Dancer of Using Flash Powder. All flash powders used by photographers are explosives and dangerous. One source of danger is that a flame must be maintained in the proximity of the powder for the purpose of igniting it. Frequently the air becomes sufficiently charged with the dust to form a means of communication between the lamp and the powder and a premature explosion results, often doing serious

damage. By , means of electricity a lamp has been devised which dispenses with the flame, and, accordingly, decreases the danger. A pan provided to receive the powder has two wires from a battery, and as these ends are covered by the powder, the explosion takes place at the desired time by causing a spark to pass between the two ends. This is done by a touch button connection. The electric-flash lamp is the patent of Simon D. Alter and Lewis T. Young of Philadelphia, Pa.
