'Vio Ray' high frequency machine

Production date
Circa 1917
 Description
The 'Vio Ray' is a version of the Violet Ray technology invented by Serbian American inventor Nikola Tesla and first introduced at the Chicago World's Fair in 1893. The machine uses a coil similar to a spark coil in a car. 'Utilizing a transformer, the voltage is increased dramatically and as it moves through the resonating coil. The device's bulb contains a gas that ionizes and produces charged particles that emanate from the surface. This combination of charges particles and high frequency produces a mild heating effect in the body (source: ‘The Healing Powers of the Violet Ray’, by Deborah Seymour Taylor).
