    September 1911] THE S.S.WHITE DENTAL MFG. CO, THE S. S. WHITE GASOMETER The strong points of the S. S. White Gasometer are its simplicity, its cleanliness, its convenience, its durability. The bell is perfectly balanced; the slightest inhalation affects it. An annular air chamber at the bottom of the bell forms the float, the perfect balance being maintained by means of ordinary gun shot in two small compartments covered with screw caps on the inner sur- face of the float. The bell, which holds eight gallons of gas, works on a nickel-plated guide rod, without unsightly gallows. The guide rod is graduated to show the quantity of gas in the bell. All parts exposed to the water are brass, insuring cleanliness and durability; zinc becomes slimy, unfit for gas to circulate through. The bell is nickel plated all over, the top burnished. The water tank is fin- ished on the outside in a blue-black bronze, oxidized, with the beads and edges nibbed through to the polished brass, the whole lacquered. The stand is of cast iron, japanned black and ornamented. Will hold either 450-gallon, 250-gallon, or 100-gallon cylinder, and is on rollers for convenience in handling. The socket (A) of the stand is for large cylinders. The reversible clamp (B) fits the large cylinders on one side, and on the other the small cylinders. The side which fits small cylinders has a flange (C) on which sits the cylinder. A set screw (D) holds the cylinder firmly in position. The reservoir (E) is filled with water to the bead (K). At the bottom of the reservoir, where the inhaler tubing is attached, is a piston valve (G), placed there for absolute security against waste when oper- ations are suspended with the receiver full of gas. At the opposite side (not seen in illustrations) is a pipe to which the cylinder yoke is connected by means of rubber tubing (L). Near the top of the reservoir is a wooden fork (H), to support the inhaler when not in use. The bell (F) works on the guide rod (I). The outfit includes yoke and plain rubber tubing (1 ft.), Inhaler No. 5, silk-covered Inhaler tubing (4 ft.), and metal connection, wheel key and Russia-iron Jackets for the large and small cylinders, everything complete, ready to attach a gas cylinder. Directions for setting up and operating accompany each Gasometer. PRICE The S. S. White Gasometer, without Gas Cylinder and Gas $75.00
