Tesla Oscillator with Mercury Interrupter:
Patent 609,24
This patent utilizes liquid-to-solid interruptions of a
centrifugal ribbon of mercury to make and break contact
with a fan blade.
Tesla Oscillator with Mercury Interrupter:
Patent 609,248

This patent utilizes a liquid-to-liquid "make", with an insulating
disk used to separate the liquids for the "break" duration. 
Tesla Oscillator for Ignition Purposes:
Patent 609,250
A Tesla Coil for igniting gas engines - a "Tesla" ignition coil.
Tesla Oscillator with Mercury Interrupter:
Patent 609,251
It's not perfect, but these still took forever to draw!
