The safetychains between the locomotive and tenderat the time the drawbar broke allowed thelocomotive and tender to separate, which. FIG. 3. FAILURE OF A CRYSTALLIZED DRAW BAR. Fig. 3 shows a drawbar which failed,causing the instant death of one companys records showed that thisdrawbar had been removed and annealed16 days prior to accident: however, ourinvestigation disclosed that the materialwas badly crystallized where it broke, and is conclusive evidence that they were notof ample strength, as required by the lawand rules, and this accident again forciblyillustrates the importance of properly con-structing, inspecting and maintaining suchparts, and cannot be too strongly im-pressed upon all concerned. Some Properties of Boiler Tubes Scientific Investigation as to the Causes of Failure Because of the failure of the tubes in abattery of Stirling boilers of the DetroitEdison Co., Prof. Albert E. White madean investigation into the causes therefor,the results of which he gave in a paperpresented to the American Society ofMechanical Engineers at its annual meet-ing in
