La locomotiva . fatto di3 16 in acciaio. Longitudinale e giunzioni di testa sono state saldate. Esso wasrated come in grado di resistere a 115 libbre di pressione e stato beingused in combinazione con una bobina riscaldatore in cui il gas è stato il carburante. Dopo l'illuminazione del riscaldatore su la mattina dell'incidente, Elbertwent torna a letto. Contrariamente alle sue intenzioni si è addormentato. Come muchas non vi è stata alcuna valvola di sfiato sul serbatoio e una valvola di ritegno nel supplyline non consentivano di sollievo in quella direzione, lo stadio è stato impostato fora violento blow-up non appena la pressione ha raggiunto un punto in cui delserbatoio non poteva più tenere.

The Locomotive . made of3 16 steel. Longitudinal and head seams were welded. It wasrated as capable of withstanding 115 pounds pressure and was beingused in conjunction with a coil heater in which gas was the fuel. After lighting the heater on the morning of the accident, Elbertwent back to bed. Contrary to his intentions he fell asleep. In as muchas there was no relief valve on the tank and a check valve in the supplyline did not permit relief in that direction, the stage was set fora violent blow-up as soon as the pressure reached a point where thetank could no longer hold it. With a roar that shook the whole neigh-borhood, the bottom head blew off and the tank shot through timbersand woodwork. No one knows how high the tank traveled after it Wliile. of course, his chosen work claims a great deal of his atten-tion, the young inspector is finding time to develop himself alongother lines.

It landed in the back yard twenty feet fromwhere it started. At Glenolden, Pa., on March 13 an explosion of a somewhat similararrangement caused about $10, 000 damage to the home of Fred Werner.Although in this case the tank did not rise up through the house, thelatter was damaged so badly that to undertake repairs was not feasible. This tank, 14^2 by 32, was connected to an automatic gas waterheater, controlled by a thermostatic valve. It had no relief valve and, as in the case first cited, a check valve prevented the pressure frombacking water out into the city mains. Apparently the thermostatfailed to close oflf the gas. The tank ripped open the full length ofthe welded longitudinal seam. While to anyone acquainted with pressure vessels it is obviousthat a relief valve is a necessity for safety, there are some systems —as the one about to be described — in which at first glance the need ofsuch a valve is not apparent. 90 THE LOCOMO
