Relief valve (R) can be adjusted as desired. Keeping the cock to the pressure gauge partlyclosed will prevent the hand from unduly vibrating. One of the Many Ways It May Be Located, is so totake cold water to the apparatus from, and put hotwater back into the pipe that supplies water for.

The hotwater from the apparatus will pass with great forcethrough the same pipe, hose, nozzles, etc., as are usedwith cold water. HOT WATER WASHOUT PLANTS A general description of what constitutes a hot water boilerwashing and boiler filling apparatus, and some of the principalfunctions and advantages. A boiler washout and filling apparatus consist of heaters,tanks, pumps, valves, temperature regulators, etc., intendedto provide hot water with which to wash out locomotive boilersand to refill them after washing. The water is heated in part^by the blow-off products from the locomotive supplemented byexhaust steam and occasionally by live steam. The tempera-ture of the washout water is maintained at approximately 130degrees and the water for refilling at 180 degrees or heat control is automatic, the apparatus provides for
