ABSTRACT:
The assembly which produces the flame is made up of a strip of conductive material, narrowed over an intermediate portion lengthwise, laminated onto a strip of combustible material such as cardboard, folded lengthwise over the strip such that the narrowed portion of the conductive strip is in a notch at one end of the combustible strip. The notched end of the combustible strip is saturated with a highly combustible material such as candle wax. Applying electrical power to the ends of the conductive strip causes the narrowed section to glow and ignite the highly combustible material and thereby the end of the combustible strip. This flame producing assembly is termed a flamestrip. The flamestrips are disposable. The flame producer includes a cassette which holds a plurality of flame strips and enables dispensing them one by one. The cassette may be adapted for attachment to a flashlight so that the power to produce the flame is drawn from the flashlight batteries. As a safety measure, two switches are used to complete the electrical circuit from the batteries through the flamestrip being dispensed. In an alternate embodiment the cassette incorporates a battery and is self sufficient; however, the battery portion of the cassette may be inserted into a specially adapted flashlight.
