32 MARINE REVIEW AND MARINE RECORD. dates APPLIES ALSO TO MARINE BOILERS. "© It's surprising to note that some of our railroads in these days of high boiler pressure will persist in the criminal practice of plugging up the holes in drilled stay bolts that have been broken in service, rather than make immediate repairs. This is generally put off until the boiler is washed out, -which may mean several weeks or a month, according to the water used. Not only is such work criminal, but it destroys the object for which the drilled bolt was adopted. Experience has taught that it is impossible, even with an expert, to locate broken bolts at all times, and it is due to this that the. drilled bolt has been adopted. At best it is only a makeshift. The drilling is gen- erally done by inexperienced labor and a large percentage of the holes are found away from the center of the bolt, which natur- ally weakens it. If it is done by the piecework system and no inspector around, cases have been found where the hole did not penetrate the thickness of the boiler shell. Adopting rules and furnishing special charts for the guidance of those whose duty it is to watch the broken bolts is a waste of time and money unless the rule is rigidly enforced. We are not quoting from hearsay, but are giving facts as we found them. On one road we counted thirty-six broken bolts on a Mogul that had not seen a year's service. Wire nails and file points were used. The en- gineer claimed that he reported them and that the boiler-maker had used the file ends in the absence of wire nails, the nails he had put in himself, taking his lesson from the boiler-maker who made repairs in that way. The master mechanic said these en- gines always came in at night and got out again before morn- ing, so that the work could not be done, as he had no night force to do this work. With the hollow bolt plugging is out of the question. If a plug is inserted from the outside, to prevent the annoying escape of steam and water, it simply drives it into the fire box, which means death to the fire. We do not believe that the parties guilty of these practices do so with any criminal in- tent, but it behooves the management to watch this more close- ly. Life and property is at stake, and certainly the crews that man these engines are due every consideration. This practice of having boiler insurance companies that make a specialty of this sort of risk do this work is a commendable one. When the inevitable explosion happens to boilers whose broken stay bolts have given due and timely warning that was disregarded, men will hold up their hands and say that the cause of the accident was a mystery. Then others interested in having the owners of the locomotive escape the penalty of the reckless practice of plugging leaky stay bolts will look wise and say that s@]e DWE VWVEVWVEVBWABBWAI™'wGY QVQEeeouses Northwestern Steam Boiler & Mfg.
