A burner construction and method of making the same are provided, the burner construction comprising a burner body having a chamber therein and having opposed ends one of which is open to the chamber and the other of which has structure for interconnecting a source of fuel to the chamber, and a removable cap closing the one end of the body, the cap having opposed sides and an annular peripheral edge interconnecting the opposed sides together, the burner construction having ports interconnecting the chamber to the exterior of the burner construction and through which the fuel can issue to burn externally to the burner construction, the cap having an annular groove in one of the opposed sides thereof and inboard of the peripheral edge thereof, the burner body having a projection disposed in the groove to hold the cap on the one end of the burner body in its closing position thereof.
In a burner construction comprising a burner body means having a chamber means therein and having opposed end means one of which is open to said chamber means and the other of which has means for interconnecting a source of fuel to said chamber means, and a removable cap means closing said one end means of said body means, said burner construction having port means interconnecting said chamber means to the exterior of said burner construction and through which said fuel can issue to burn externally to said burner construction, the improvement wherein said body means has an annular surface means interrupted by a plurality of radially disposed groove means that are spaced apart by land means of said annular surface means and that define a generally repeating pattern of a set of a certain number of said groove means and said land means separated from the next adjacent set of said certain number of said groove means and said land means by one of said land means that is not part of said sets and that has an annular length that is longer than the annular length of any one of said land means of said sets separated thereby and wherein said cap means has an annular surface means cooperating with said annular surface means that has said groove means therein to close said groove means on one end thereof whereby said groove means define said port means, said annular surface means that has said groove means therein having an igniter receiving slot means therein, the slot means causing a side of a groove means at opposite ends of said slot means to be deleted and an igniter assembly having a part thereof disposed in said slot means and defining a missing side of each of the two of said groove means that are respectively disposed on opposite sides of said igniter assembly.
In a method of making a burner construction comprising a burner body means having a chamber means therein and having opposed end means one of which is open to said chamber means and the other of which has means for interconnecting a source of fuel to said chamber means, and a removable cap means closing said one end means of said body means, said burner construction having port means interconnecting said chamber means to the exterior of said burner construction and through which said fuel can issue to burn externally to said burner construction, the improvement comprising the steps of forming said body means to have an annular surface means interrupted by a plurality of radially disposed groove means that are spaced apart by land means of said annular surface means and that define a generally repeating pattern of a set of a certain number of said groove means and said land means separated from the next adjacent set of said certain number of said groove means and said land means by one of said land means that is not part of said sets and that has an annular length that is longer than the annular length of any one of said land means of said sets separated thereby, forming said cap means to have an annular surface means cooperating with said annular surface means that has said groove means therein to close said groove means on one end thereof whereby said groove means define said port means, forming said annular surface means that has said groove means therein to have an igniter receiving slot means therein, the slot means causing a side of a groove means at opposite ends of said slot means to be deleted, and disposing part of an igniter so that said igniter assembly defines a missing side of each of two of said groove means that are respectively disposed on opposite sides of said igniter assembly.
