Abstract: 129,980. Foltz, I. J. July 12, 1918, [Convention date]. Atmospheric gas and vapour burners; vaporizing-apparatus.-A gas or vapour burner comprises upper and lower mixing-chambers, tubular burner heads connected to the upper mixing-chamber, two burner heads positioned at the sides and connected to the lower mixing-chamber, and valves rotatably and longitudinally movable in the mixing-chambers and adapted to direct the gaseous mixture to the upper or lower sections of the side burner heads, or to one end of the side burner heads, or to one or more of the tubular burner heads. When employing vaporizing - apparatus, the arrangement of valves enables any or all of the vaporizing-tubes to be employed, and the vapour generated to be supplied to any of the burner heads. The vaporizing-tubes are heated by one of the tubular burner heads, and the vapour tubes are kept hot by means of an auxiliary burner head forming a side extension of the tubular burner head. Figs. 3 and 10 show two cross-sectional views of a vapour burner adapted to rest on the grate bars of the fire-box of a kitchen stove or like device. The upper tubular burner heads 3, 4, 5 comprise slotted tubes capable of being turned for directing the flame in any direction, whilst the outer faces of the side burner heads 6, 7 are flat and slotted, each side burner head consisting of an upper and a lower section. Vaporizing-tubes 8, 9, enclosed by a hood 66a, extend longitudinally above the tubular burner head 5 and terminate in downwardly extending pipes 17, through which the vapour passes to mixing-tubes 19 communicating with the mixing-chambers 40, 2 and axially adjustable in the burner casing so that the internal air supply can be adjusted. The pipes 17 are kept hot by means of a slotted burner head 20 communicating with the burner head 5. The controlling-valves 25, 26, 27 consist each of a semi-cylindrical sleeve portion 29 and an end disk 28, and are slidably and rotatably mounted in the burner casing, the valves being operated by a rod 30 and a handle 31 outside the stove. The mixing-chambers are divided into two compartments by a central partition, so that, by sliding one of the valves 26, 27, gaseous mixture can be supplied from the corresponding mixing tube to one end of the corresponding side burner head, or to both ends, or to neither; and, by turning one of these valves, gaseous mixture can be supplied to either or both the upper and lower sections of the side burner head, or can be directed into the lower mixing-chamber 40 and thence to 'the other side burner head, or by means of the third controlling-valve 25 to the uppertubular burner heads. Each of the tubular burner heads is provided with an independent regulating-valve comprising two semicylindrical sleeve portions 29<a>, Fig. 5, separated by a central disk member 28a, so that the gaseous mixture can be admitted through an opening 50, Fig. 10, in the lower and central part of each tubular burner head, or can be shut off. Kerosene is supplied to the starting-pan 60 from a measuring-tank 62 provided with inlet and outlet regulating needle valves 65, 64 provided with handle's having a projecting-lug 66, with which a rooking-catch 67 engages so that one needle-valve can be opened when the other is closed. Kerosene is supplied... after starting, from the tank 62 to a chamber 14 communicating by means of needle valves 16 with the vaporizing-tubes. The upper part of the burner casing is slotted so as to form an auxiliary pilot burner head 65<a>, Fig. 5, for transferring the flame from one end of a tubular burner head to the other.
