Arrangement of Auxiliaries in Engine Room of the Robert W. Stewart room there is one American Blower fan driven by a reciprocating steam engine with a capacity of about 9000 cubic feet. In the engine room there_is a ballast pump 16 x 10 x 14 inches of duplex type. This pump may also be used for fire purposes. The boiler feed system is served by one main feed pump 12 x 7 x 12 inches duplex PILOT HOUSE type and by an auxiliary pump of 12 x 7 x 12 inches duplex type. In ad- dition there are also two Metropolitan double tube two-inch injectors. Usual lake practice has been fol- lowed in the layout of the sanitary system. The necessary sanitary water supply is furnished by a 6 x 6 x 6 inches horizontal duplex pump fitted with a governor set at 45 pounds. at @& @)\(S © ons There are two hot water tanks for furnishing hot water to officers and men, one forward and one aft. All pumps except as noted are of Dean make. It is of utmost importance that the drinking water should be pure and the Ropert W. STEWART is equipped with a Griscom-Russel distilling ap- paratus consisting. of an evaporator, distiller and filter with a capacity of 50 gallons per hour. After being dis- tilled the water is drained through the distiller into a tank from which the drinking water pump of duplex type, 3 x 2 x 4 inches in size de- livers it to a tank on the upper deck. From the latter tank drinking water is then supplied by gravity to the faucets and drinking founts in various places. The practice of attaching auxiliary pumps to the main engine undoubtedly reduces the steam consumption for the services that these pumps take care of. In the past it has been the custom to attach an air pump and a bilge pump. In this vessel there are no pumps attached to the main engine and this is undoubtedly better en- gineering practice. With this ar- rangement there is complete freedom and flexibility. The auxiliary ser- vices do not depend on the main en- gine and the main engine does not need to depend upon the attached pumps. The air pumps are of the steam jet type and there is also a separate 6 x 6 x 6-inch bilge pump in the lower engine room. Two Electric Generating Sets Electricity for light and all other purposes is supplied from two 15- kilowatt, 115 volt, direct current, Eng- berg generators direct connected to FORECASTLE DECK Arrangement of Pilot House and Captain’s Quarters on the Robert W.
