  • Patent number: 6289887
    Abstract: An artificial campfire device is disclosed and is fueled by a pressurized fuel source. The device includes a base receptacle which defines an open top, the base receptacle being adapted for placement on a ground surface. A burner member is positioned within the receptacle and is adapted to provide a flame of variable height. A fuel control mechanism is adapted for coupling a pressurized fuel source with the burner member for controlling the flow of fuel to the burner member and the size of flame emitted by the burner member. Finally, a plurality of artificial refractory log members are adapted for assembly in crisscross fashion to form a log cluster in the base receptacle.

  • Patent number: 6044836
    Abstract: An artificial campfire device is disclosed. The device is fueled by a pressurized fuel source and is adapted for permanent mounting to a fixed ground member. The device includes a base receptacle having a peripheral edge defining an open top and an interior bottom surface. The base receptacle is mountable to the fixed ground member. A burner member is mounted to and positioned above the interior bottom surface and is adapted to provide a flame of variable height. A fuel control mechanism is adapted for coupling a pressurized fuel source exterior to the receptacle base with the burner member to control the flow of fuel to the burner member and the size of flame emitted thereby. Finally, a plurality of artificial refractory log members are secured to each other in crisscross fashion to form a log cluster, and the log cluster is permanently secured to the base receptacle bottom surface.

  • Patent number: 5901697
    Abstract: A portable artificial campfire device is disclosed. The device includes a receptacle having upper and lower portions, an open top defined by a peripheral edge of the upper portion, and an interior bottom surface. A burner is positioned above the interior bottom surface and is adapted to provide a flame of variable height. A pressurized fuel source is positioned exterior to the receptacle, and a control member couples the fuel source with the burner for controlling the flow of fuel to the burner and the size of flame emitted by the burner. A plurality of artificial refractory log members are secured to each other in crisscross fashion to form a log cluster. A structure is provided for supporting the log cluster within the receptacle. Finally, a mechanism is provided for selectively adjusting the vertical position of the log cluster in the receptacle to vary the vertical position of the log cluster relative to the plane the open top.
