1 7 IMPROVED COOKING GAS BURNER ABSTRACT THE PRESENT INVENTION PROVIDES A COOKING GAS BURNER ASSEMBLY INCLUDING A DISTRIBUTOR 5 (30), A GAS MANIFOLD (50) AND A CUP (40), SAID COP (40) BEING LOCATED BETWEEN SAID GAS MANIFOLD (50) AND SAID DISTRIBUTOR (30). THE INVENTION ALSO PROVIDES A METHOD OFASSEMBLING A DISTRIBUTOR (30) AND A CUP (40) IN A COOKING GAS BURNER ASSEMBLY, SAID METHOD INCLUDING THE STEPS OF PROVIDING: SAID DISTRIBUTOR (30) WITH DOWNWARDLY EXTENDING SPIGOTS (32), PROVIDING SAID CUP (40) WITH 10 RECESSES (48) TO RECEIVE SAID SPIGOTS (32), SAID RECESSES (48) INCLUDING A BASE SURFACEBASE SURFACE (246), SAID RECESSES (48) BEING SIZED AND OR SHAPED WHEREBY THERMAL EXPANSION OF SAID DISTRIBUTOR (30) RESULTS IN SUBSTANTIALLY NO INCREASE IN THE CONTACT SURFACE BETWEEN SAID CUP (40) AND DISTRIBUTOR (30), WHEN SAID DISTRIBUTOR (30) IS HOT COMPARED TO WHEN IT IS COLD.. 1 5 THE INVENTION FURTHER PROVIDES A BUMER ASSEMBLY HAVING AT LEAST A CAP (220) AND A DISTRIBUTOR (30) ON WHICH SAID CAP (220) IS MOUNTED, SAID DISTRIBUTOR (30) INCLUDING AN INTERNAL AND AN EXTERNAL CROWN OF FLAME PORTS, AND AT LEAST ONE CROSS LIGHTING PASSAGE (37) THERE BETWEEN. SAID CAP (220) INCLUDING AN APERTURE (222) THERE THROUGH WHICH IS ADAPTED TO BE POSITIONED OVER SAID CROSS LIGHTING PASSAGE (37)WHEN SAID CAP (220) AND 20 DISTRIBUTOR (30) ARE ASSEMBLED. THE INVENTION FINALLY PROVIDES A COOKING GAS BUMER ASSEMBLY HAVING A DISTRIBUTOR (30) AND A FIRST FORMATION TO SUPPORT SAID DISTRIBUTOR ('30) IN SAID ASSEMBLY, SAID DISTRIBUTOR (30) AND SAID FIRST FORMATION INCLUDING SPIGOTS (32) AND RECESSES (48) TO ALLOW SAID FIRST FORMATION TO SUPPORT SAID DISTRIBUTOR (30), SAID RECESSES (48) INCLUDING A SURFACE BEING 25 SIZED AND OR SHAPED WHEREBY THERMAL EXPANSION OF SAID DISTRIBUTOR (30) RESULTS IN SUBSTANTIALLY NO INCREASE IN THE CONTACT SURFACE AREA BETWEEN SAID FIRST FORMATION AND DISTRIBUTOR (30), WHEN SAID DISTRIBUTOR (30) IS HOT COMPARED TO WHEN IT IS COLD. |
