Its practicability in this new field, however,has been clearly demonstrated by the results secured by theIndianapolis Traction & Terminal Companys mechanicaldepartment. L. M. Clark, master mechanic, who made theinitial installation of this type of welding apparatus, hasobtained exceedingly satisfactory results with it in his shops,and new work is being found for the equipment almostdaily. One man is now kept at work with the welding outfitcontinually, and it is expected that a second equipment willbe purchased in the near future so that two operators maybe employed to take care of the large amount of work whichmay be handled by this means. The original installation was made about two years agoand comprised an Oxweld ioo-lb. duplex acetylene gen-erator, a number of oxygen and acetylene cylinders forportable work, the necessary regulators, blowpipes, welding. Oxy-Acetylene Welding—Motor Frame Worn Through bySuspension Bar Between Lugs head and welding material furnished by the Ox-WeldAcetylene Company of Chicago. In looking around for aman to operate the plant a car repairman of average intel-ligence was selected. After receiving instructions from oneof the manufacturers experts, which extended over a periodof about ten days, it was decided that the companys mancould go ahead on his own responsibility. EARLY EXPERIMENTS At first Mr. Clark gave considerable personal attention tothe plant in order to determine its adaptability to the re-quirements encountered in his own shop practice, and al-though he had familiarized himself with the various classesof work which were usually handled by this process beforepurchasing the plant, he soon discovered that numerousother savings were possible. The convenience of being ableto repair in a short time truck frames and motor frameswhich under ordinary conditions would have gon
