GRAVITY BOILER WASHING SYSTEM The purpose of all hot water locomotive boiler washing sys-tems is to reclaim the greatest possible amount of heat from theblow-off in order that hot water for washing and filling may beobtained with a minimum expenditure of live steam. In theWinters gravity system of locotnotive boiler washing the ma-terial used in tlie construction of the plant has been chosen and ■llMirTUM W,\T«p_t««. Hot Water Boiler Washing and Filiing Piant forces the valve open. In doing this the inner piston over-travels six grooves leading from the annular chamber, thusallowing live steam to enter the cylinder. The constructionof the valve is such that its operation in opening and closingshould not be accompanied by a serious shock. The length the tanks have been arranged with especial attention to theconservation of heat. This system, which is being placed onthe market by the George M. Newhall Engineering Company,Philadelphia, Pa., is shown in the accompanying plant consists of two standard 3 in. cypress tanks, one S46 RAILWAY AGE GAZETTE, MECHANICAL EDITION Vol. No. 10 submerged within tlie other. The outside tank forms the hotwell into which the locomotives are blown off, the inside tankcontaining water for refilling. The hot well is equipped witha copper lined hopper bottom which guides the mud depositedfrom the blow-oft water to a central opening lead
