There were no batteries used on Dr. Tesla's Colorado Springs coil!

Yes Sandy, I have talked on the subject on numerous occasions. The idea is
that when a large inductance has it's supply voltage cut off suddenly the
collapsing magnetic field develops a high counter E.M.F. which is then used
to drive the Tesla coil. This is also the principle of the handheld Tesla
coils used for vacuum testing and the old "violet-ray" coils. Below is an
ASCII drawing of the layout.

You have an iron core coil connected at one side of it's windings to
the line. The other side of the coil connects to a vibrating armature
almost identical to those found on the old induction coils. The
stationary contact of the interrupter is connected to the Tesla coil
primary P, the other side of the primary is connected to the Tesla
coil secondary S. the primary also connects to the moving contact of
the interrupter and the capacitor C is across the vibrating spark gap
VG. There should be an adjusting screw that pushes the moving
armature of the vibrating spark gap closer to or further away from
the stationary contact. Instructions for building several different
size Tesla coils driven by a "kicking coil" are described in
Thomas Stanley Curtis's "High Frequency Apparatus" 1916
(reprinted by Lindsay Publications 1988)in chapter VIII
"Kicking Coil Apparatus".
