The inventions : researches and writing of Nikola Tesla, with special reference to his work in polyphase currents and high potential lighting
A technical compilation of Nikola Tesla's patents, lectures and papers edited by Thomas Commerford Martin, published in New York by The Electrical Engineer in 1894 for electrical engineers and instrument makers. The 178 line engravings give motor and dynamo cross-sections, hatched machine castings, coil windings, and wiring schematics with lettered keys — sources of concentric circle patterns, engraved shading, and circuit diagram linework.
