1 Be it known that we,"Ronsa'r GI FoRn States, and both residingat Chicago, county of Cook, and [State of Illinois, ha'veinvented 5 certain new and usefulv Improvements in lvas'hing' and Filling Systems for'Locomotive-Boilers. y

This invention relates to \v' shing out and filling systems for locomotive-boilers and it. has fOl'ltif; salient. objects to provide an ap- 'pa'ratus by 'which nearlyall ofthe-units of heatieontained in blown out Wa-ter can be recovered and transmitted to fresh supplies of'water to be'used for heating or other 7 purposes asfor refilling and washing loco- ;motive boilers; to provide anapparatusso organized that the waste-water front. the

' 1 boilers is transferred to a closed tank and the heat off the steam, incident to the relief o'f pressure. utilized for. heating other. water, and lower'pressure steam taken off and simi-;: lai-lyaitilizeclfby creating a partial vacuumin .tlie. reheating apparatus to provide a;

mechanism so organized that-1n .the event of a deficiency of heat froni waste water, a

supplemental"supply derived from steam.

from an auxiliary soureefwill be automatically turned into the heating apparatus to bring the ufatcr-to the desired temperature;

' to provide an" apparatus so organized that the supplementalsteam used for'boostmg will be utilized, not for heat-ingthe' entire supply, hut-"only; somuch thereof as is nectein. so organized that the steam. evolvcdl' from the \vasto water andntlllzed for heatessary for immediateusg thereby insuring both economy and rapid heating of the water.

The operation of the system can now be followed. Valves 12 and 2l.and 68 are"normally closed and valve 10 is opened 'to"1'al-' low the. hot water and steam to flow from 1 the boiler into the'vat' compartment2, this compartment being sufficie'ntly lar etoreceiveand to hold all the water -llle water. and steam coming :from the boiler have-still considerable pressure, and temperature,"and when the large vat is reached the-pressure isimmediately relieved and thegwater be .gins to boil.
