An interesting manifold system of valveshas been worked out in connection with the pumps. By meansof these valves, which are located at the side of the pumps, itis possible to make any combination of pipe connections fromthe floor without the annoying and time-taking work of climb-ing all over the boiler room to change valves. The details ofthis manifold system of valves are illustrated in a pumps are provided with Lunkenheimer mechanical lubri-cators. The exhaust lines from the engines to the condenser. INTERIOR OF POWER STATION, SHOWING DIRECT-CONNECTED GENERATING SETS is a Hoppes closed type live-steam purifier, consisting of alarge drum provided with numerous shells. Two Worthington 9-in. x 534-in. x 10-in. inside-plunger typeduplex pumps take the water from the heater and pass itthrough the purifier. The water flows over a series of shellsand comes into contact with live steam from the boilers, whichprecipitates all impurities. The bottom of the purifier is 6 the boilers and the water flows by gravity to the boilers,flow being aided by the steam pressure in the purifier. Eitherof the boiler feed-pumps are amply large enough to supply thefull capacity of the boilers, and the piping is arranged so thatthey can take water directly from the hot well to theboilers, if necessary, or can deliver cold water from the coldwell. Adjoining the boiler-feed and hot-well pumps is a Still- have Hoppes heaters, purifiers, steam separators and oil elim-inator
