  • Fuel/air supply assembly for gas burners
    Patent number: 5873713
    Abstract: A pair of spaced tubular half-shells are stamped in each of two separate sheets of metal which are then joined at their margins to form two mixer tubes each having an inlet end with a venturi for connection to a fuel gas supply and an outlet end adapted for connection to a burner. The space between the mixer tubes is stamped to form a pair of grooves which lock and seal the sheets together to prevent the fuel/air mixture from leaking from one mixer tube to the other.
