Moreover, since the connectors a, b, and e are joined to each other by resistances (filaments) which are practically equal, the current through each of the three resistances becomes practically uniform. It will be obvious that should the number of phases be increased above three the number of rotation current receivers (mains) and the number of connecting-resistances (filaments in the glow-lamps) should be correspondingly increased. The shape or arran gement of the filaments may also be varied in many details, provided the fundamental idea be adhered to of the multiphase current entering the lamp through as many connectors as there are phases and passing through a number-of filaments of equal resistance connected to each connector and forming equal resistances between the various mains.

Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States, is-

1. A system for operating glow-lamps by means of multiphase currents, which consists in a number or rotation-current conductors corresponding to the number of phases of the current, any desired number of glow-lamps, a numberof current-introducers to each lamp equal to the number of said conductors and connected to the said conductors, and glowbodies at the interior of the lamp electrically connected to each other and to pairs of the said current-introducers, substantially as described.

2. In a system for operating glow-1amps by means of multiphase currents, the combination, with a multiphase dynamo, of a number of rotation-current conductors deriving their electricity from the terminals of the said dynamo, any desired number of glow-lamps connected to the said conductors and having a number of leading-in wires corresponding to that of the said rotation-current conductors, with glow-bodies at the interior of the lamp electrically connected to each other and connecting the said leading-in wires in series, substantially as described.

3. A system for operating glow-lamps by means of three-phase currents, which consists in three rotation-current conductors, any desired number of glow-lamps, a current-introdueer from each of said conductors electrically connected to each lamp, and three glowbodies at the interior of the lamp electrically connected to each other and to the said current-introducers, substantially as described.

at. A system for operating glow-lamps by means of three-phase currents, which consists in three rotation-current conductors, any desired number of glow-lamps, a leading-in wire from each of said conductors to each lamp, and three filaments connecting the three leading-in wires with each other in series, substantially as described.

5. A system for operating glow-lamps by means of three-phase currents, which consists in three rotation-current conductors, any desired number of gloW-lamps,aleading-in wire from each of said conductors to each lamp, and three filaments of equal length, each connected at one end to one of said leading-in wires and connected at the other to the ends of the other two filaments, substantially as described.

In testimony whereof I al'tix my signature in presence of two witnesses.
