This flame safety lamp was manufactured in the mid-1800's by the American Safety Lamp and Mine Supply Company of Scranton, Pennsylvania. The lamp is called a safety lamp because it can be used safely in the presence of flammable gas. In 1815, inventor Sir Humphry Davy discovered that surrounding the flame with a fine wire gauze would cool the flame to such an extent that it could not ignite the gas surrounding the lamp. In 1813 William Clanny’s safety lamp innovation was the use of glass to surround the flame, and later safety lamps often feature both wire gauze and a glass globe at the lamps bottom.
