Abstract
Abstract An elongated burner body having a series of fuel ports extending along the axis of the burner body is provided with a crossover fuel aperture adjacent the fuel inlet end of the burner. A crossover body comprising a hollow transversely extending member is provided with a crossover fuel inlet aperture from the downstream edge of which extends a depending scoop element. The crossover body is assembled on the burner body so that the crossover fuel apertures are in registration with each other. The scoop serves as a means for locating the crossover body with respect to the burner body and to direct fuel from the burner into the crossover. The scoop element is provided with an opening which allows a portion of the fuel mixture to pass through the opening to directly supply gas to the burner fuel ports most closely adjacent to the crossover and thereby to provide a dependable source of fuel for smooth ignition by the crossover.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
276 words
A gas burner comprising an elongated hollow gas burner body having fuel inlet opening means adjacent one end thereof, said burner body having fuel burner port means extending along the top side thereof for discharging said fuel mixture along a substantial portion of the axial length of said burner body, a crossover fuel aperture formed in the top side of said burner body between said one end of said burner body and the other end thereof; a crossover body mounted on said burner body, said crossover body being hollow and forming a crossover fuel passage extending transversely of said burner body, said crossover body defining crossover fuel port means having a portion thereof disposed adjacent the fuel burner port means in said burner body and extending transversely therefrom, said crossover body having a crossover fuel inlet aperture formed on the bottom side thereof disposed in registration with said crossover fuel aperture on the top side of said burner body, and a crossover scoop element extending downwardly from the downstream edge of the crossover fuel aperture in the crossover body through the crossover fuel aperture in the burner body into the interior thereof to deflect a portion of fuel mixture from the interior of said burner body into said crossover body for passage through said crossover fuel port means, said crossover scoop element having an opening formed therein to allow another portion of the fuel mixture to pass from said one end of said burner body through said opening in the scoop element to a portion of the fuel burner port means in the burner body located adjacent the crossover fuel port means of said crossover body.
Claim 2
Dependent Claim
276 words
A gas burner comprising an elongated hollow gas burner body having fuel inlet opening means adjacent one end thereof, said burner body having fuel burner port means extending along the top side thereof for discharging said fuel mixture along a substantial portion of the axial length of said burner body, a crossover fuel aperture formed in the top side of said burner body between said one end of said burner body and the other end thereof; a crossover body mounted on said burner body, said crossover body being hollow and forming a crossover fuel passage extending transversely of said burner body, said crossover body defining crossover fuel port means having a portion thereof disposed adjacent the fuel burner port means in said burner body and extending transversely therefrom, said crossover body having a crossover fuel inlet aperture formed on the bottom side thereof disposed in registration with said crossover fuel aperture on the top side of said burner body, and a crossover scoop element extending downwardly from the downstream edge of the crossover fuel aperture in the crossover body through the crossover fuel aperture in the burner body into the interior thereof to deflect a portion of fuel mixture from the interior of said burner body into said crossover body for passage through said crossover fuel port means, said crossover scoop element having an opening formed therein to allow another portion of the fuel mixture to pass from said one end of said burner body through said opening in the scoop element to a portion of the fuel burner port means in the burner body located adjacent the crossover fuel port means of said crossover body.
Claim 3
Dependent Claim
20 words
A gas burner as defined in claim 1, wherein said opening in the scoop element comprises a centrally disposed slot.
Claim 4
Dependent Claim
38 words
A gas burner as defined in claim 1, wherein said scoop element comprises a pair of tabs extending downwardly from the bottom of said crossover body, said opening in the scoop element comprising a slot between said tabs.
Claim 5
Dependent Claim
62 words
A gas burner as defined in claim 1, wherein said crossover scoop element has a transverse dimension substantially the same as the transverse dimension of the crossover fuel aperture in said burner body so that the scoop element serves as a locating means for said crossover body on said burner body and as a sealing means between said crossover and burner bodies.
Claim 6
Dependent Claim
265 words
A gas burner comprising an elongated hollow gas burner body having fuel inlet opening means adjacent one end thereof, said burner body having fuel burner port means extending along the top side thereof for discharging a fuel mixture along a substantial portion of the axial length of said burner body, a crossover fuel aperture formed in the top of side of said burner body between said one end of said burner body and the other end thereof; a crossover body mounted on said burner body, said crossover body being hollow and forming a crossover fuel passage extending transversely of said burner body, said crossover body defining crossover fuel port means having a portion thereof disposed adjacent the fuel burner port means in said burner body and extending transversely therefrom, said crossover body having a crossover fuel inlet aperture formed on the bottom side thereof disposed in registration with said crossover fuel aperture on the top side of said burner body, and a crossover scoop element extending downwardly from the downstream edge of the crossover fuel aperture in the crossover body through the crossover fuel aperture in the burner body into the interior thereof to deflect a portion of fuel mixture from the interior of said burner body into said crossover body for passage through said crossover fuel port means, said crossover scoop element having a transverse dimension substantially the same as the transverse dimension of the crossover fuel aperture in the burner boDy so that the scoop element serves as a locating means for assembling the crossover body on the burner body during assembly thereof.
Claim 7
Dependent Claim
265 words
A gas burner comprising an elongated hollow gas burner body having fuel inlet opening means adjacent one end thereof, said burner body having fuel burner port means extending along the top side thereof for discharging a fuel mixture along a substantial portion of the axial length of said burner body, a crossover fuel aperture formed in the top of side of said burner body between said one end of said burner body and the other end thereof; a crossover body mounted on said burner body, said crossover body being hollow and forming a crossover fuel passage extending transversely of said burner body, said crossover body defining crossover fuel port means having a portion thereof disposed adjacent the fuel burner port means in said burner body and extending transversely therefrom, said crossover body having a crossover fuel inlet aperture formed on the bottom side thereof disposed in registration with said crossover fuel aperture on the top side of said burner body, and a crossover scoop element extending downwardly from the downstream edge of the crossover fuel aperture in the crossover body through the crossover fuel aperture in the burner body into the interior thereof to deflect a portion of fuel mixture from the interior of said burner body into said crossover body for passage through said crossover fuel port means, said crossover scoop element having a transverse dimension substantially the same as the transverse dimension of the crossover fuel aperture in the burner boDy so that the scoop element serves as a locating means for assembling the crossover body on the burner body during assembly thereof.
Claim 8
Dependent Claim
67 words
A gas burner as defined in claim 5, wherein said crossover scoop element has an opening formed therein to allow another portion of the fuel mixture to pass from said one end of the burner body through said opening in the scoop element to a portion of the fuel burner port means in the burner body located adjacent the crossover fuel port means of the crossover body.
