Method of constructing and assembling burners

Claim 1

A METHOD OF CONSTRUCTING AND ASSEMBLING A GAS BURNER OF THE TYPE HAVING A RADIATION SURFACE RENDERED INCANDESCENT BY THE COMBUSTION OF FUEL THEREON OR ADJACENT THERETO, SAID GAS BURNER COMPRISING A HOUSING FORMING A MIXING CHAMBER FOR GASEOUS FUEL AND AIR, A MIXING TUBE WITHIN SAID HOUSING ADAPTED TO CONVEY A MIXTURE OF FUEL AND AIR INTO SAID MIXING CHAMBER, SAID MIXING TUBE HAVING AN INLET ADJACENT ONE END OF SAID HOUSING TO PROVIDE A SUBSTANTIALLY CYLINDRICAL LOCATING SURFACE THEREIN, A BOSS ON SAID ONE END OF SAID HOUSING PROVIDING AN AIR ASPIRATOR OPENING AT SAID INLET END OF SAID MIXING TUBE, SAID METHOD COMPRISING THE STEPS OF PROVIDING AN UNFINISHED GAS BURNER HOUSING, FORMING A FIRST GAUGING SURFACE ON SAID BOSS NORMAL TO THE LONGITUDINAL AXIS OF SAID LOCATING SURFACE AND USING SAID LOCATING SURFACE AS A GUIDE, PROVIDING A FLUID CONDUIT AND A FLANGE, FORMING AN OPENING IN SAID FLANGE CENTRALLY THEREOF AND LOCATING MEANS IN PREDETERMINED RELATION WITH SAID OPENING, SECURING SAID CONDUIT IN SAID OPENING WITH THE AXIS OF SAID CONDUIT NORMAL TO SAID FLANGE AND IN PREDETERMINED RELATION TO SAID LOCATING MEANS WHEREBY SAID FLANGE PROVIDES A SECOND GAUGING SURFACE, MOUNTING A FUEL NOZZLE ON SAID CONDUIT COAXIALLY OF SAID CONDUIT AND IN PREDETERMINED RELATION TO SAID SECOND GAUGING SURFACE, PROVIDING LOCATING MEANS ON SAID FIRST GAUGING SURFACE SO POSITIONED THAT WHEN SAID FIRST AND SECOND GAUGING SURFACES ARE PLACED IN FULL SURFACE CONTACT AND THE RESPECTIVE LOCATING MEANS ON SAID SURFACES ARE ALIGNED WITH ONE ANOTHER, THE FUEL NOZZLE WILL EXTEND INTO SAID GAS BURNER AND HAVE ITS LONGITUDINAL AXIS IN SUBSTANTIALLY EXACT COINCIDENCE WITH THE LONGITUDINAL AXIS OF SAID MIXING TUBE, PLACING SAID FIRST AND SECOND GAUGING SURFACES IN FULL SURFACE CONTACT, ALIGNING SAID LOCATING MEANS, AND SECURING SAID SURFACES RIGIDLY TO ONE ANOTHER IN THIS POSITION.

Claim 2

A METHOD OF CONSTRUCTING AND ASSEMBLING A GAS BURNER OF THE TYPE HAVING A RADIATION SURFACE RENDERED INCANDESCENT BY THE COMBUSTION OF FUEL THEREON OR ADJACENT THERETO, SAID GAS BURNER COMPRISING A HOUSING FORMING A MIXING CHAMBER FOR GASEOUS FUEL AND AIR, A MIXING TUBE WITHIN SAID HOUSING ADAPTED TO CONVEY A MIXTURE OF FUEL AND AIR INTO SAID MIXING CHAMBER, SAID MIXING TUBE HAVING AN INLET ADJACENT ONE END OF SAID HOUSING TO PROVIDE A SUBSTANTIALLY CYLINDRICAL LOCATING SURFACE THEREIN, A BOSS ON SAID ONE END OF SAID HOUSING PROVIDING AN AIR ASPIRATOR OPENING AT SAID INLET END OF SAID MIXING TUBE, SAID METHOD COMPRISING THE STEPS OF PROVIDING AN UNFINISHED GAS BURNER HOUSING, FORMING A FIRST GAUGING SURFACE ON SAID BOSS NORMAL TO THE LONGITUDINAL AXIS OF SAID LOCATING SURFACE AND USING SAID LOCATING SURFACE AS A GUIDE, PROVIDING A FLUID CONDUIT AND A FLANGE, FORMING AN OPENING IN SAID FLANGE CENTRALLY THEREOF AND LOCATING MEANS IN PREDETERMINED RELATION WITH SAID OPENING, SECURING SAID CONDUIT IN SAID OPENING WITH THE AXIS OF SAID CONDUIT NORMAL TO SAID FLANGE AND IN PREDETERMINED RELATION TO SAID LOCATING MEANS WHEREBY SAID FLANGE PROVIDES A SECOND GAUGING SURFACE, MOUNTING A FUEL NOZZLE ON SAID CONDUIT COAXIALLY OF SAID CONDUIT AND IN PREDETERMINED RELATION TO SAID SECOND GAUGING SURFACE, PROVIDING LOCATING MEANS ON SAID FIRST GAUGING SURFACE SO POSITIONED THAT WHEN SAID FIRST AND SECOND GAUGING SURFACES ARE PLACED IN FULL SURFACE CONTACT AND THE RESPECTIVE LOCATING MEANS ON SAID SURFACES ARE ALIGNED WITH ONE ANOTHER, THE FUEL NOZZLE WILL EXTEND INTO SAID GAS BURNER AND HAVE ITS LONGITUDINAL AXIS IN SUBSTANTIALLY EXACT COINCIDENCE WITH THE LONGITUDINAL AXIS OF SAID MIXING TUBE, PLACING SAID FIRST AND SECOND GAUGING SURFACES IN FULL SURFACE CONTACT, ALIGNING SAID LOCATING MEANS, AND SECURING SAID SURFACES RIGIDLY TO ONE ANOTHER IN THIS POSITION.
