Burner construction and method of making the same

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 main 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, one of said body means and said cap means having an annular surface means interrupted by a plurality of radially disposed main 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 main groove means and said land means separated from the next adjacent set of said certain number of said main 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, the other of said body means and said cap means having an annular surface means cooperating with said annular surface means that has said main groove means therein to close said main groove means on one end thereof whereby said main groove means define said main port means, each said land means having a free end surface means that faces said annular surface means of the other of said body means and said cap means, the improvement comprising the steps of forming said free end surface means of said land means that are not part of said sets to each have a small radially disposed groove means therein that leads from said chamber means to the exterior of said burner construction and that is closed on one end thereof by said annular surface means of said other of said body means and said cap means to provide small carry-over flame means between said sets of main groove means adjacent that respective land means that is not part of said sets, forming each said small groove means to have an inner end and an outer end, and forming said outer end of each said small groove means to be wider than said inner end thereof.
