Total Claims: 3
Claim 1
Independent Claim
356 words
A pedestal mounted gas fueled barbeque grill comprising, an open upper-ended housing having means defined by a first imaginary horizontal plane for supporting a cooking grate, a burner enclosure disposed within said housing, said enclosure including a bottom wall portion and a peripheral side wall means within said housing defined in part by a second imaginary horizontal plane spaced vertically below said first mentioned plane engageable with said enclosure for supporting said enclosure within said housing, said burner enclosure being provided with support means defined by a third imaginary horizontal plane spaced vertically below said second mentioned plane, a burner assembly supported upon said support means, means defining a fuel-air mixture inlet opening in said bottom wall portion of said burner enclosure and baffle means interposed between said opening and said burner assembly, whereby an air-fuel mixture supplied through a pedestal supporting said grill and introduced through said opening will be dispersed in a uniform manner towards the underside of said burner assembly, said burner assembly comprising a generally horizontally disposed partition supported at said third mentioned imaginary plane by said support means, said partition being formed with a plurality of spaced apart openings, a plurality of open lower sided, generally cup-shaped burner units associated one with each of said openings, said units being fabricated of a porous screen material and being complementary in shape to said openings and extending upwardly therethrough from the underside of said partition, each of said burner units including a peripheral flange portion engaged with and secured to the underside of said partition around the periphery of the associated of said openings, a layer of a porous wire screen of a smaller mesh size than said burner units disposed below said partition and being generally co-extensive therewith between said support means, and a support grate supported in a position generally coplanar of said second mentioned imaginary plane and having a layer of rock-like material supported thereon for catching any excess food drippings or the like which may be produced when food is being cooked on said first mentioned grate and thereby minimize the transfer of such drippings toward said burner assembly.
Claim 2
Dependent Claim
356 words
A pedestal mounted gas fueled barbeque grill comprising, an open upper-ended housing having means defined by a first imaginary horizontal plane for supporting a cooking grate, a burner enclosure disposed within said housing, said enclosure including a bottom wall portion and a peripheral side wall means within said housing defined in part by a second imaginary horizontal plane spaced vertically below said first mentioned plane engageable with said enclosure for supporting said enclosure within said housing, said burner enclosure being provided with support means defined by a third imaginary horizontal plane spaced vertically below said second mentioned plane, a burner assembly supported upon said support means, means defining a fuel-air mixture inlet opening in said bottom wall portion of said burner enclosure and baffle means interposed between said opening and said burner assembly, whereby an air-fuel mixture supplied through a pedestal supporting said grill and introduced through said opening will be dispersed in a uniform manner towards the underside of said burner assembly, said burner assembly comprising a generally horizontally disposed partition supported at said third mentioned imaginary plane by said support means, said partition being formed with a plurality of spaced apart openings, a plurality of open lower sided, generally cup-shaped burner units associated one with each of said openings, said units being fabricated of a porous screen material and being complementary in shape to said openings and extending upwardly therethrough from the underside of said partition, each of said burner units including a peripheral flange portion engaged with and secured to the underside of said partition around the periphery of the associated of said openings, a layer of a porous wire screen of a smaller mesh size than said burner units disposed below said partition and being generally co-extensive therewith between said support means, and a support grate supported in a position generally coplanar of said second mentioned imaginary plane and having a layer of rock-like material supported thereon for catching any excess food drippings or the like which may be produced when food is being cooked on said first mentioned grate and thereby minimize the transfer of such drippings toward said burner assembly.
Claim 3
Dependent Claim
43 words
A gas fueled barbeque grill as set forth in claim 1 wherein said housing is fabricated of a cast metal and wherein said support means defined in part by said second imaginary plane comprises inwardly projecting shoulder means formed integrally of said housing.
