Tesla’s Patents 6481 and 6502

6481. “Improvements relating to the electrical transmission of power and to apparatus therefor.” H. H. Lake. (Communicated from abroad by N. Tesla, of New York.) Dated May 1. 8d. A motor is employed in which there are two or more independent energising circuits through which are passed alternating currents, which effect a progressive shifting of the magnetism or of the “lines of force” which, in accordance with well known theories, produces the action of the motor. The claims are 8 in number.

6502. “Improvements relating to the generation and distribution of electric currents and to apparatus therefor.” H. H. Lake. (Communicated from abroad by N. Tesla, of New York.) Dated May 1. 8d. Relates to those systems of electrical distribution in which a current from a single source of supply in a main or transmitting circuit, is caused to induce, by means of suitable induction coils, a current or currents in an independent working circuit or circuits. The main objects of the invention are the same as have heretofore been obtained by the use of these systems, viz., to divide the current from a single source whereby a number of lamps, motors, or other translating devices may be independently controlled and operated by the same source of current, and in some cases to reduce a current of high potential in the main circuit to one of greater quantity and lower potential in the independent consumption circuit or circuits. The claims are 4 in number.
