Steam boiler explosions, in theory and in pactice; . ed. A few minutes before noon, while the engine wasrunning at the usual speed, the steam-gauge indicatingforty-seven pounds pressure, and the water-gauges show-ing the usual amount of water, the middle one exploded; THE RESULTS OE EXPLOSIONS. 137 the shell burst open and was nearly all stripped off. Theremainder of the boiler was thrown high in the air. While this boiler was in the air, No. 1, the left-handboiler, having been forcibly struck by parts of No. 2,also gave way, so that its main portion was projectedhorizontally to the front, arriving at the front wall ofthe building in time to fall under No. 2, as shown inFig. 38. The most probable method of rupture is indi-cated in Fig. 38, as the line A B separates a ring ofplates which was found folded together beneath the pileof debris. If the initial break had been at some pointon the bottom, this belt of plates would have beenthrown upward and flattened, instead of downward,where it was folded by the flood of water from No. Fig. 39.—Initial Rupture. The third boiler was raised from its bed by the issuingwater, and thrown about fifty feet to the right of itsoriginal position. These two boilers contained probably more than four-teen tons of water, which had a temperature due toforty-seven pounds of steam, and the effect of its sud- 138 STEAM BOILER EXPLOSIONS. den liberation equalled that of several hundred pounds ofexploded gunpowder.
