I claim: 1. A gas burner comprising a tubular member disposed in generally circular shape with its upper surface interrupted at one side and with its cross-sectional area decreasing from one side to the other, a tubular supply member connected thereto at the side having the larger cross-sectional area and cast integrally therewith, said first-named tubular member having a slot cut through the upper surface thereof and extending around the member from one side of said interruption to the other side of the same, and a pilot burner disposed in" the space formed by said interruption directly above said supply tube and having means to direct a starting flame to said slot.
2. A gas burner comprising a tubular member having a slot cut through the walls thereof and walls of substantial thickness to prevent deformation of said slot, dead ends disposed in said tubular member to form a space therebetween, a supply tube passing through said space to the opposite side of the burner at a height in said space lower than the upper surface of the tubular member, and a pilot burner disposed in the space S formed by said dead ends and directly above said O0 supply tube to direct a starting flame to said S slot.
3. A gas burner comprising a circular tubular S member and a supply tube integrally cast thereS with in one piece, a hollow segment horizontally disposed at the front of said burner and integrally s cast to the inner surfaces of said tubular member and to the supply tube, the said supply tube cont taining a passage that merges with the internal e channel of the tubular member through baffles vertically placed in the outlet end of said supply S60 tube to direct the flow of the gas, and the said tubular member being depressed at the front thereof to form a space above the supply tube, r a pilot burner disposed in said space directly r above the supply tube, a slot in the upper surface y 65 of the tubular member with continuous extent from one side of said space to the other side s thereof to form a jet for the gas, and the internal S channel of said tubular member gradually dee creasing in cross-sectional area in its travel from e 70 the front to the rear of the burner to maintain the s pressure of the gas with decrease in volume.
