Eco Gilbarco Model 98 Texaco Air Pump w/Light Kit

Eco Model 98 Texaco Air Pump with porcelain Gilbarco face, light kit and water spigot. Serial #8P 10350, Model 98, Spec No 98 1001, Code W. Height 50", width 17", base 8.5". The first ECO air meter was made around 1916 or 1917 by the Western Manufacturing Company, of Oskoloosa, Iowa. It appears that the first ECOs were actually called the Economy Air Meters. The name was then shortened to ECO. The ECO does not produce air, it only meters it. It operates by air pressure, not by electricity. When you lift the hose from the hook it opens the mechanism allowing the air to circulate. Once the chuck is placed on the valve stem of the tire, a shot of air is sent into the tire. It then stops and reads the pressure of the tire to see if it the same as what the setting is. If it is not the same, another shot of air is sent into the tire. Each time it does this, the bell rings. It works like this: SHOT....READ....SHOT....READ....SHOT.... It will continue to do this until the pressure in the tire is the same as the pressure that was set on the mechanism. This is what the words "BALANCE INFLATION" on the top chrome piece means.
