Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
In combination with a first wall having at least one burner port extending therethrough, a second wall spaced from the first wall and forming a passageway therewith for flow of combustion air to the port, an improved burner apparatus and means for supplying pressurized gaseous fuel thereto, said apparatus having a portion thereof disposed within the passageway and including at least one conduit having an inlet and an outlet end, said outlet end being disposed adjacent the port and being formed with at least one discharge orifice directing the gaseous fuel along a path offset from the central axis of the conduit, and said inlet end including means for changing the location of said gaseous fuel discharge path, the last name means comprising a threaded portion formed along the outer periphery of said inlet end.
Claim 2
Dependent Claim
135 words
In combination with a first wall having at least one burner port extending therethrough, a second wall spaced from the first wall and forming a passageway therewith for flow of combustion air to the port, an improved burner apparatus and means for supplying pressurized gaseous fuel thereto, said apparatus having a portion thereof disposed within the passageway and including at least one conduit having an inlet and an outlet end, said outlet end being disposed adjacent the port and being formed with at least one discharge orifice directing the gaseous fuel along a path offset from the central axis of the conduit, and said inlet end including means for changing the location of said gaseous fuel discharge path, the last name means comprising a threaded portion formed along the outer periphery of said inlet end.
Claim 3
Dependent Claim
