The machine runs quietly on any cir-cuit without trouble, and delivers a current of any quantityand character, independent of the primary current. Fromthe ordinary incandescent light circuit a small volume ofcurrent at a voltage of no may be transformed to a largervolume of current with a voltage of from 3 to 6 volts, thusmaking a saving of 50 per cent, over the old method ofusing the electric current in a large amount directly througha series of lamps or other resistance.
