The system described in this article uses a com-bination of oxygen and illuminating gas taken from the citymains. One of the illustrations shows the apparatus as set upin a permanent installation, although, by the use of flexibleconnections a portable outfit may easily be constructed. Theilluminating gas passes from the meters to a water jacketedbooster K which is driven by a small electric motor; thisbooster is used to raise the pressure of the gas. its maximumcapacity being 30 lbs. per sq. in., although more than 14 never required for even the heaviest cutting, as this pressurelias proved sufficient when cutting steel bars 8 in. the booster the gas passes upward through the pressureregulating waterseal L, then through the pipe M to the pres-sure gage and the specially constructed reducing valve .V. which. Burner for Welding and Cutting with Oxygen and Illuminating Gas. reduces the pressure to that required for whatever class ofwork is being done. From the reducing valve the gas passesdirectly through the pipe O to the burner where it is com-bined with the oxygen. The use of tanked oxygen, as in other welding processes, isrecommended. The oxygen is stored in the tanks P and passesthrough the small coil pipe to the reducing valve Q, fromwhich it passes through the pipe R to the burner. The maxi-mum pressure used in the oxygen for welding is 25 lbs. persq. in., and for heavy cutting up to 90 and 100 lbs. The illus-tration shows a two-torch outfit, but they may be built to anyrequired size and there is one 14-torch outfit in successfuloperation. The other illustration shows the construction of the burneror torch. This burner insures the complete mixture of thegases by means of the multiple stage system of mixing chambersand has been approved by the New York Municipal
