Tesla's New Oscillator

An Invention the Fruit of Ten Years’ Research

New York, Oct. 2. - Nikola Tesla has explained the principles of the electric oscillator for which he has just obtained a patent. He has been working on the idea for ten years.

“The object of my oscillator,” said Mr. Tesla, “is to provide a simple, compact and effective apparatus for producing greater effects with existing circuits carrying direct currents. Practical electricity is too expensive, it must be cheapened so the multitude may have advantage of it. That is all I am aiming at.

“My new invention is simply this: In any given circuit I interpose a device in the nature of a choking coil, in order to give the circuit a high self induction. I also provide a circuit controller that may be operated to make and break the circuit. Around the point of interruption I place a condenser to store the energy of the discharge current, and in series with such condenser I place a transformer, which becomes the source of currents of high frequency.

“Inasmuch as the self induction of the circuit through which the condenser discharges, as well as the capacity of the condenser itself may be given practically any desired value. The frequency of the discharge current may be adjusted at will.”
