The design and construction of a practical wireless telegraph station (1910)
Spurck, Robert Michael, Wheatlake, Burton Cyrenius Job · leaf 11
on the roadto his investigations was the accidental discovery that the dis-charge of a Leyden jar or induction coil through a coil of in-sulated wire would incite induced currents in a similar coilprovided there waa a spark gap in the first. This then gave amethod of detecting electric waves in… … Figure 3. Figure 1. 1. Fahie History of Wireless Telegraphy, Page 179. 3 A spark gap was provided in the center, in his experimentsthis exciter was charged by an induction coil. The detector (Figure 3) consisted of a wire bent in acircle having a spark gap similar to that of the exciter circuit,but…
