Y., with capa-city of 50,000 gallons and 100 feet SAN FRANCISCO VALVE. These steel tanks have been primar-ily used for waterworks systems. Wheregravity systems are desirable and nonatural elevation is available, steeltanks have a wide use. The tanks areconstructed with hemispherical bot-toms and large diameter riveted steelriser pipes which are more permanentthan small pipes with wood frost cas-ing. The bottom of the riser is equippedwith inlet pipe flanges, manhole andblow-ofT valve, having an operatingmechanism for discharging sedimentwithout emptying the tank. The illus-tration shows a 560,000 gallon tankwith 12 posts, 70 ft. top, built for thecity of Lakewood, O. AN OPERATING AND REGULAT-ING VALVEEquipped With a Self-Locking San Francisco type of Tro-jan operating and regulating valve 367 has a very useful feature in the handlewhich allows continuous operation ofthe valve without continuous handle is fitted with a spring lever,at the end of which is a is made to fit into notches whichare
