Pancake Tesla Coil Operated with Carpentier Style Interrupter:  Electric Autographs

This coil was producing snake-like strobing negative discharges 4-5" long, interposed with very distinct branching positive discharges 3" long.  Current consumption:  100 watts at 110VAC.

Lichtenberg Figures in Crookes vacuum
These figures are unfortunately unclear due to the near
impossible circumstances of trying to photograph them -
they were created using a burned out Edison bulb with
a straight filament.  The filament heavily bombarded
was spinning around the tube, and when it hit the glass
formed rapid moving Lichtenberg Figures.

Frank found a real gem here!  He won't tell me when he gets it up and running, because he knows I'll fly there and will never leave!!
Rogers Violet Ray
One of the few Violet Rays with a provision made to keep the electrode from spinning around.
Westinghouse Stopper Bulb
Tesla saved the day with this clever bulb.  Still intact, luckily it found a safe home with Frank!

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 609,248

This patent utilizes a liquid-to-liquid "make", with an insulating
disk used to separate the liquids for the "break" duration. 
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 609,251
It's not perfect, but these still took forever to draw!

Harry, I can't thank you enough for this.  I've searched years
for this issue with no luck!  For me, this is the greatest

By popular request, here's a high resolution scan of this article...
it's a good one!
We've recently acquired 3 large 3-phase variable transformers. ("Variacs" type transformers, manufactured by Powerstat)
Divided they form 3 single phase autotransformers.  We need only
1 unit, the other two are FOR SALE!
Reproduction Thompson Plaster Spark Gaps
These gaps are unique in that they are stationary, yet adjustable through the use of a sliding arm that short circuits the number of gaps not wanted in the circuit.  They are ideal for voltages from 3,500 - 25,000V or more.
