It has not yet been found possible with this system to weld either wrought iron or steel, but the welding of cast iron inmedium thicknesses has proved successful and and wrought iron may be readily cut and steel bars upto 8 in. square have been cut with great success. The processis especially adapted for the smaller sizes of iron castings andis most economical and efficient on brass and aluminum is quite applicable to such work as the repairing of brasscastings, the filling in of blow holes and in boiler shops, par-ticularly, for the cutting of plates; there are also many oppor-tunities lor its use in electric railroad repair shops as well. Apparatus for Welding and CuttingGas ■ith Oxygen and Illuminating as in signal work. The process has been developed byE. Raven Rosen-Baum, consulting engineer on high temperaturegases, 607 West Forty-third street, New York, and all the ap-paratus has been patented by him. QUADRUPLE COMBINATION MACHINE The design of this machine was the result of the experiencewith the Oeking solid steel frame triple combination is a quadruple combination machine, which the manufacturersterm the Imperator type, and is being placed on the marketby the Wiener Machinery Company, New York, as managers forthe Oeking Company, Dusseldorf, Germany. The machine is theresult of careful study and contains in one frame, ready forwork, all the tools for a large variety of cutting, shearing, co-ping, mitering and notching. It is claimed that it is the onlymachine of the kind that is in actual operation. The frame ismade of steel in one piece and the machine is sufficiently com- Au
