Abstract

992,063. Gas burners. BRITISH OXYGEN CO. Ltd. Jan. 10, 1962 [Jan. 10, 1961], No. 1040/61. Heading F4T. A device for effecting the combustion of a mixture of butane or propane and air comprises a housing 1 adapted to releasably support a container 2 for the fuel gas, a piercing means 5 arranged to puncture a seal 7 on the container, a mixing chamber having an inlet for the admission of the combustion supporting gas and a forward outlet 16 for the discharge of the gas mixture, a flow path from the container 2 to the mixing chamber which includes control means 11 and a vaporizing chamber, the vaporizing chamber being located wholly rearwardly of the outlet 16 from the mixing chamber. As shown, the container 2 is held by a strap 3 against pin 5 which is hollow and has side apertures to enable the fuel gas to pass from the container into a recess 6 and hence into the vaporizing chamber. The vaporizing chamber comprises two concentric tubes 8 and 9, the inner tube 8 containing a wire to limit the flow of any liquified fuel passing through from the container (Fig. 3, not shown). From the vaporizing chamber the fuel gas passes through control valve 11, through nozzle 13 to the rearward end 14 of the mixing chamber where it mixes with air which enters the mixing chamber from under cover 17 (Fig. 1, not shown). In a modification, the vaporizing chamber may constitute a coiled tube situated adjacent the mixing chamber or wound round it. The device may be constructed in the form of a blow-lamp, picnic stove or as a source of illumination.
