  • Such an apparatus comprising a source of light, simulated flame effect means for reflecting said light to simulate frames, simulated fuel means illuminated by the light source to simulate a bed of combusting fuel, and screen means to view an image of the simulated flames.
  • screen means is positioned between said flame effect means and said simulated fuel means.
  • the screen means is capable of diffusely transmitting light reflected by the said flame effect means and also capable of reflecting light from the simulated fuel means so that the simulated flames means appear to emanate between the simulated fuel means and an image of the latter means reflected in said fuel means, such as described in UK Patent Specification No. 2230335 .
  • Another type of apparatus often used includes a translucent screen supported on a frame.
  • the translucent screen is usually of a synthetic plastics material and a red lamp is mounted behind the screen to provide a light source.
  • the light source may be directed from moving light reflecting elements onto the rear surface of the screen.
  • the shadow of an irregularly shaped fuel simulating member may also be projected onto the rear surface of the screen.
  • UK Patent Specification No. 1457540 describes another such device.
  • the flame effect is provided by using a movable element between a screen and the light source.
  • an apparatus for simulating a solid fuel flame including:
  • a translucent refractor panel is mounted between the container and the screen.
  • the refractor panel is a frosted panel.
  • At least one face of the refractor panel has a roughened surface.
  • At least one face of the refractor panel has an uneven surface.
  • the refractor panel is coloured.
  • the refractor panel is a glass panel.
  • the container has a number of spaced-apart indentations In a sidewall of the container.
  • said indentations are randomly dispersed around the sidewall of the container.
  • said indentations include a number of shallow Indentations at translucent portions of the sidewall, said shallow indentations formed by cut-out grooves in the side wall of the container.
  • said indentations include deep indentations which project into an interior of the container.
  • said deep indentations are formed by deformations in the sidewall of the container.
  • the container is formed from glass.
  • the sidewall of the container must be at least partially translucent to allow through passage of light and may be partially or fully transparent.
  • the screen comprises a reflective plate mounted behind the container and extending upwardly above the container.
