Abstract
A battery powered, hand-held, lightweight electrical shocking device provides a visible and audible display of sparks continuously upon the operation of a switch. The device is capable of delivering a jolting shock. The display of sparks makes clear the nature of the device and serves as a deterrent to unruly persons. The device is comprised of a non-conductive housing in a generally annular shape, permitting it to be gripped in one hand. On one surface away from the hand are first and second conductive plates separated from each other by an insulator. The electrical circuit comprises a free-running multi-vibrator, a small transformer, a rectifier, a voltage doubler and an internal spark gap. The circuit can deliver a series of short duration, high voltage, low current electrical shocks from two penlight batteries.
