Tesla Coils Resurrected

The article by Willis L. Nye that follows was short on construction details and long on uses in wireless telegraphy such as testing insulation, looking for shorts, antenna systems, leaky capacitors, etc. This has been edited out to save space for other articles. The basic construction details for the Tesla coil have been retained. There are two circuits on which this project may be energized. (1) Use of an induction coil and, (2) a circuit for a standard high voltage transformer. A novel feature of both circuits is the use of a horn gap to neutralize peak voltages on the input side. (Thanks to Ed Taylor for sending this one in to TCBA).

A Practical High Frequency Coil

By Willis L. Nye
Here is shown a cross-section of the Tesla coil with the plan of the base. A magnetic interrupter gap is shown also and the cross-section of the very substantial condenser required for this apparatus.
This is the layout of the circuit, using the spark coil system for the energy supplied. Note the protection afforded by the grounded horn gap.
Here the Tesla coil is supposed to be supplied from the standard lighting circuit, using the power transformer described above. Again the grounded horn gap is used to protect the system.
