Abstract
Abstract A gas-fired broiler having a compacted volume of trap rock interposed between a grill which supports the edibles and a primary source of heat which cooks the edibles. The trap rock provides both a substantially uniform temperature cooking surface and a noncombustible collector and absorber of liquid animal fats. A member capable of being heated to incandescence is positioned between the primary source of heat and the trap rock pack acting as a distributor of the heat from the burner to the whole area of the trap rock pack.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A gas-fired roller comprising: an elongated housing having spaced-apart broadsides and opened along one surface in the direction of its length, means extending along said broadsides of said housing, said means dividing said housing into a grill section adjacent said one surface and a firebox section underlying said grill section, an atmospheric burner positioned within said firebox and extending in the direction of the length of said firebox for supplying the primary source of heat, said burner having two spaced-apart parallel rows of evenly spaced burner ports, heat dissipation means comprising an expanded metal housing enclosing a compacted porous volume of trap rock bodies, said heat dissipation means overlying said burner, and an incandescent radiating member interposed in the space between said burner and said heat dissipation means, said radiating member responsive to said burner for incandescently radiating heat to said heat dissipation means and for directing the products of combustion from said burner to said heat dissipation means providing a substantially uniform layer of heat across said heat dissipation means.
Claim 2
Dependent Claim
171 words
A gas-fired roller comprising: an elongated housing having spaced-apart broadsides and opened along one surface in the direction of its length, means extending along said broadsides of said housing, said means dividing said housing into a grill section adjacent said one surface and a firebox section underlying said grill section, an atmospheric burner positioned within said firebox and extending in the direction of the length of said firebox for supplying the primary source of heat, said burner having two spaced-apart parallel rows of evenly spaced burner ports, heat dissipation means comprising an expanded metal housing enclosing a compacted porous volume of trap rock bodies, said heat dissipation means overlying said burner, and an incandescent radiating member interposed in the space between said burner and said heat dissipation means, said radiating member responsive to said burner for incandescently radiating heat to said heat dissipation means and for directing the products of combustion from said burner to said heat dissipation means providing a substantially uniform layer of heat across said heat dissipation means.
Claim 3
Dependent Claim
27 words
A gas-fired broiler according to claim 1, wherein said radiating member is operatively connected to said burner means and extends away therefrom toward said heat dissipation means.
Claim 4
Dependent Claim
41 words
A gas-fired broiler according to claim 2 wherein said radiating member is a Y-shapEd member connected to said burner between said parallel rows of evenly spaced burner ports and the arms of said Y-shaped member extend underlying said heat dissipation means.
Claim 5
Dependent Claim
31 words
A gas-fired broiler according to claim 1 wherein said radiating member comprises an expanded metal housing enclosing a compacted porous volume of trap rock bodies capable of being heated to incandescence.
Claim 6
Dependent Claim
26 words
A gas-fired broiler according to claim 4 wherein said heat dissipation means and said radiating member form an unitary structure having an air space sandwiched therebetween.
Claim 7
Dependent Claim
132 words
A broiler comprising: an elongated rectangular housing having spaced-apart broadsides enclosed at each end and opened at the top, support means mounted along said broadsides and dividing said housing into a grill section overlying a firebox section, an elongated tubular burner extending in the direction of the greatest length of said housing and supported within said firebox section substantially midway between said spaced-apart broadsides, and a radiating shield member connected to said burner along a vertical plane bisecting the axis of said burner, said shield extending away from and to either side of said burner in an arc toward each of said broadsides, said member shielding said burner from said grill section and radiating the heat from said burner across said grill section to provide a uniform temperature across said grill section.
Claim 8
Dependent Claim
132 words
A broiler comprising: an elongated rectangular housing having spaced-apart broadsides enclosed at each end and opened at the top, support means mounted along said broadsides and dividing said housing into a grill section overlying a firebox section, an elongated tubular burner extending in the direction of the greatest length of said housing and supported within said firebox section substantially midway between said spaced-apart broadsides, and a radiating shield member connected to said burner along a vertical plane bisecting the axis of said burner, said shield extending away from and to either side of said burner in an arc toward each of said broadsides, said member shielding said burner from said grill section and radiating the heat from said burner across said grill section to provide a uniform temperature across said grill section.
Claim 9
Dependent Claim
79 words
The broiler according to claim 6 further comprising a heat dissipation means mounted on said support means and extending in said grill section toward said opening in said housing, said heat dissipation means comprising a bed of trap rock bodies capable of being heated by the radiated heat from said radiating shield member and by the convected products of combustion directed from said burner to the outer edges of said bed of trap rock by said radiating shield member.
