Patent ID: 7670136

Claim:
An artificial acetylene gas candle comprising: a first cylinder comprising a cylindrical wall, a closed bottom end, and an open top end, the cylindrical wall and the closed bottom end forming a fuel chamber adapted to contain calcium carbide fuel; a second cylinder comprising a cylindrical wall, an open bottom end, and a partially closed top end defining an aperture within the top end, the open bottom end adapted to slidingly engage the first cylinder, an inner diameter of the second cylinder sized relative to an outer diameter of the first cylinder such that water is drawn by capillary action into a gap between the first and second cylinders and into the first cylinder when the first and second cylinders are at least partially immersed in water; a third cylinder comprising a cylindrical wall, a closed bottom end, and an open top end, the third cylinder adapted to receive water and to receive the slidingly-engaged first and second cylinders such that the first and second cylinders are at least partially immersed in water within the third cylinder; a fourth cylinder comprising a cylindrical wall, an open bottom end, and a partially closed top end defining an aperture within the top end, the fourth cylinder sized to be received snugly by the second cylinder top end aperture; and a fifth cylinder comprising a cylindrical wall, an open bottom end, and an open top end, the fifth cylinder sized to be received snugly by the fourth cylinder top end aperture; wherein water drawn into the first cylinder contacts the calcium carbide fuel resulting in formation of acetylene gas, and wherein the acetylene gas exits the artificial candle through the fourth and fifth cylinders to be ignited.
