  • Gas burner
    Patent number: 4222526
    Abstract: A burner formed from a sheet metal pressing doubled over to define a gas manifold has alternating flame ports 15 and 16 along one edge. Between the flame ports curled over tabs 19 and 20 define horizontally-directed retention flame ports 21. The tabs 19 and 20 also serve to clamp the edges of the pressing together against the strains of thermal cycling, eliminating the need for spot welding.
