  • Patent number: 4869662
    Abstract: A flame extinguishing device for use with an ornamental lamp having a base, a chimney, and a wick which provides a lamp flame, includes a plate coupled inside of the chimney below the flame. The plate has a hole in the center thereof surrounding the flame but below the flame. As the plate is lifted above the flame, a low pressure area is formed below the plate. The pressure differential between the bottom of the plate and the top of the plate causes combustion by-products above the flame to flow downward through the hole. As the combustion by-products flow past the flame, oxygen is temporarily prevented from reaching the flame, thus extinguishing it. Therefore, extinguishing the flame is a simple matter of lifting the chimney an inch or so. The plate may include side holes which prevent the flame from being extinguished when the chimney and plate are placed on the lamp when the flame is burning.
