Abstract

Abstract A burner having a pan containing a loose body of gas-diffuser particles having a surface coating adapted to realistically simulate a bed of glowing coals and ashes in the presence of burning gas, is positioned beneath a log-holding grate having a lift-off loose positioning attachment thereto, the pan and diffuser body dispersing the gas emitted from burner orifices with maximum realism of simulation of a log fire.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 229 words
In a gas log assembly, in combination: a burner comprising a tube having a gas-emitting orifice; a pan for holding a gas-diffuser bed of loose, noncombustible particles covering said burner tube and dispersing the gas jet issuing from said orifice for burning at thE surface of said body; said pan having a bottom for resting flatly on a hearth in a horizontal plane and its front being completely open so that said bed can extend beyond its front margin and rest directly on the hearth so as to conceal said front margin; said pan having an upstanding back to contain the rear portion of said bed and having generally triangular ends with free margins sloping downwardly and forwardly from the upper margin of said back to the plane of said bottom at the forward margin thereof, said sloping margins functioning as guides to determine a slope for the forward surface of said gas-diffuser bed, said burner being disposed above said bottom and closely adjacent thereto intermediate its forward margin and said back; said pan being attached to said burner in fixed relation thereto; a grate disposed above said burner when resting on said hearth; and means for loosely coupling said grate to said pan to position the grate with reference to the pan and burner while allowing the grate to be freely lifted off the burner and pan assembly.
Claim 2
Dependent Claim 229 words
In a gas log assembly, in combination: a burner comprising a tube having a gas-emitting orifice; a pan for holding a gas-diffuser bed of loose, noncombustible particles covering said burner tube and dispersing the gas jet issuing from said orifice for burning at thE surface of said body; said pan having a bottom for resting flatly on a hearth in a horizontal plane and its front being completely open so that said bed can extend beyond its front margin and rest directly on the hearth so as to conceal said front margin; said pan having an upstanding back to contain the rear portion of said bed and having generally triangular ends with free margins sloping downwardly and forwardly from the upper margin of said back to the plane of said bottom at the forward margin thereof, said sloping margins functioning as guides to determine a slope for the forward surface of said gas-diffuser bed, said burner being disposed above said bottom and closely adjacent thereto intermediate its forward margin and said back; said pan being attached to said burner in fixed relation thereto; a grate disposed above said burner when resting on said hearth; and means for loosely coupling said grate to said pan to position the grate with reference to the pan and burner while allowing the grate to be freely lifted off the burner and pan assembly.
Claim 3
Dependent Claim 60 words
The combination defined in claim 1, wherein said loosely coupling means comprises a pair of fingers projecting downwardly from said pan; and respective coupling clips on said fingers, defining vertical slots in which vertical edges of said back are loosely received to position said grate relative to said burner while allowing the grate to be freely lifted off the burner.
Claim 4
Dependent Claim 38 words
The combination defined in claim 2, wherein said back has a pair of vertical open notches in its upper marginal portion, one side of each notch defining one of the vertical edges loosely received in said coupling clips.
Claim 5
Dependent Claim 28 words
The combination defined in claim 2, wherein said back has a pair of vertical slots adapted to receive said clips, said vertical edges being defined within said slots.
Claim 6
Dependent Claim 28 words
The combination defined in claim 1, including said gas-diffuser bed comprising a main body of silica grains contained in said pan in a heap covering said burner tube.
Claim 7
Dependent Claim 72 words
The combination defined in claim 1, including said gas-diffuser bed comprising a main body of silica grains contained in said pan in a heap covering said burner tube; and a thin surface coating of asbestos particles mixed with a minor proportion of larger particles of artificial volcanic rock and cinders adapted when areas of said coating are contacted by flames, to simulate glowing coals and ashes on the surface of said bed.
Claim 8
Dependent Claim 87 words
The combination defined in claim 1, including said gas-diffuser bed comprising a main body of silica grains contained in said pan in a heap covering said burner tube; and a thin surface coating of asbestos particles mixed with a minor proportion of larger particles of artificial volcanic rock adapted when areas of said particles are contacted by flames, to simulate glowing coals and ashes on the surface of said refractory body; said thin coating further including expanded mica particles mixed with said asbestos and volcanic rock particles.
Claim 9
Dependent Claim 47 words
The combination defined in claim 1, including said gas-diffuser bed comprising a main body of silica grains contained in said pan in a heap covering said burner tube; said gas-emitting orifice being disposed on the underside of said burner tube and directing the emitted gas jets downwardly.
