Abstract: The simulated log fireplace apparatus housing forming a fire box having back, bottom, top wall, two side walls, and an open front containing at least one artificial log and simulated flame sheet. A blower directs air on to the flame sheet to simulate real flame movement. A colored light source provides color of real flames. The light source and blower are adjustable from a control panel under a top louver panel. The artificial log may include a translucent base log and ember bed with a light source beneath the translucent log. A window log having an aperture simulate a burning core. A transparent partition has a partially opaque area just above the simulated flame sheet provides the full depth of real fireplace. The apparatus may include electric blower heater, a crackle box, decorative simulated brick panels placed on back and side walls, metal screen, glass doors, vents and louvers.

Abstract: The simulated log fireplace apparatus having a housing (14) forming a fire box having a back wall (22), bottom wall (18), top wall (16), two side walls (23a,b) and an open front side (11) containing at least one artificial log (32) and simulated flame sheets (33) therein. A blower (50) directs air on to the simulated flame sheets to simulate the movement of real flames. A colored light source (39) provides the color of real flames. The light source and blower are adjustable from a control panel (21) under a louver panel (47) in a top front of the apparatus. The artificial log may include a translucent base log (32) on an ember bed (26) with a white light source (31) beneath the translucent log. A window log (29) having an aperture (26) simulate a burning core of a real log. A transparent partition (45) that has a partially opaque area (55) just above the simulated flame sheets helps to further simulate appearance and depth of a real fireplace.

Abstract: An artificial log burning fireplace assembly which produces a visual effect indistinguishable from a real log burning flame in a fireplace. The assembly includes one or more artificial logs lying horizontal along the front of the fireplace. A rod lies horizontally behind the artificial logs. A plurality of elongated pieces of colored fabric are spaced apart and one short end of each piece of colored fabric is attached to the rod. A pair of electrically powered blowers are positioned behind the artificial logs and each blower is mounted near one end of the rod. The blowers are angled one to the other to create in the region surrounding the pieces of colored fabric a turbulent air flow in the region surrounding the pieces of colored fabric thereby creating a visual effect that is indistinguishable from a real log burning flame in a fireplace.

Abstract: To make imitation coal elements, in the form of pellets or lumps which will glow and radiate heat effectively when heated by a gas flame in an open-type firegrate, use is made of raw ceramic bulk fibers. An appropriate mass thereof is moistened with a stiffening agent such as potato starch and is then squeezed to shape it into its pellet or lump shape and to express any excess stiffening agent; then it is baked to set the stiffening agent and fix the shape of the pellet or lump. Thereafter the element is colored by use of a black metallic oxide/colloidal sodium silicate impregnant which is applied twice in successive dipping and baking operations.
