Original patent lithograph for Nikola Tesla's "Apparatus for Producing Currents of High Frequency" one page, 7 x 10.75, June 8, 1897. The diagram features views of the device from multiple angles. Marked at the bottom: "The Norris Peters Co., Photo-Litho, Washington, D.C." Includes the printed United States Patent Office specification sheet, two pages on one sheet, which describes the invention as an "improvement in the apparatus for the conversion of electrical currents of ordinary character—such, for instance, as are obtainable from the mains of municipal electric light and power systems and either continuous or alternating—into currents of very high frequency and potential." In fine condition.
