5 INCH INDUCTION COIL, 1950's

In several of Jules Verne's science-fiction novels, so-called "Ruhmkorff lamps" are mentioned. These were an early form of portable electric lamp. The lamp consisted of a Geissler tube that was powered by a battery-powered Ruhmkorff induction coil, an example of one (made much later)is shown here.

Your comments:

• I restored an identical model about 10 years ago. The secondary winding was badly corroded due to poor storage, and the contacts on the interrupter needed a touch of fine emery paper as they were very pitted. The re-wound coil gives 1/2 sparks when run at 4-6 volts.
