Abstract
Abstract A pair of metal plates having face-to-face channels are secured together and sealed at their edges by ceramic enamel. The plates define manifold chambers communicating with the channels and an annular burner, having burner holes near its top, is secured to the plates at the manifold chamber. A depression in a side of the burner has openings for directing jets of gas fuel to mix near an igniter tube and to move upwardly toward the burner holes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A top burner for a gas range, comprising: upper and lower plates secured together in face-to-face relation by spaced spot welds and configured to define therebetween at least one elongated gas passage; one of said plates having a boundary edge lying within the peripheral edge of the other plate and defining therewith a groove extending along said boundary edge; and a layer of ceramic enamel covering the outer surfaces of said plates, said ceramic enamel filling said groove and being bonded therein to thereby seal the joint between said boundary edge and said other plate.
Claim 2
Dependent Claim
95 words
A top burner for a gas range, comprising: upper and lower plates secured together in face-to-face relation by spaced spot welds and configured to define therebetween at least one elongated gas passage; one of said plates having a boundary edge lying within the peripheral edge of the other plate and defining therewith a groove extending along said boundary edge; and a layer of ceramic enamel covering the outer surfaces of said plates, said ceramic enamel filling said groove and being bonded therein to thereby seal the joint between said boundary edge and said other plate.
Claim 3
Dependent Claim
33 words
A burner as defined in claim 1 wherein said other plate is provided with a rib extending along and adjacent said boundary edge, said boundary edge and said rib defining said groove therebetween.
Claim 4
Dependent Claim
53 words
A burner as defined in claim 1 wherein said plates are provided with aligned openings therethrough, the periphery of the opening in said other plate having a peripheral flange extending through the opening in said one plate adjacent the boundary edge thereof, said groove being defined by said flange and said boundary edge.
Claim 5
Dependent Claim
71 words
A gas burner comprising means defining an upstanding gas fuel chamber and burner openings around the upper periphery of said chamber; an inwardly extending depression in a sidewall of said chamber below said burner openings; an igniter tube having an open end adjacent and facing said depression; and an upwardly directed opening through the bottom portion of said depression for directing gas fuel from said chamber upwardly toward said burner openings.
Claim 6
Dependent Claim
71 words
A gas burner comprising means defining an upstanding gas fuel chamber and burner openings around the upper periphery of said chamber; an inwardly extending depression in a sidewall of said chamber below said burner openings; an igniter tube having an open end adjacent and facing said depression; and an upwardly directed opening through the bottom portion of said depression for directing gas fuel from said chamber upwardly toward said burner openings.
Claim 7
Dependent Claim
40 words
A gas burner as defined in claim 4 including a further opening in said depression arranged to direct gas fuel outwardly toward said igniter tube and across the path of flow of fuel gas issuing from said upwardly directed opening.
Claim 8
Dependent Claim
49 words
A gas burner as defined in claim 5 wherein said depression is defined by side surfaces tapering generally upwardly and outwardly; and additional openings through said side surfaces arranged to direct additional gas fuel from said chamber to mix with gas fuel from said upwardly directed and further openings.
Claim 9
Dependent Claim
21 words
A gas burner as defined in claim 6 wherein said upwardly directed opening is larger than said further and additional openings.
