from The Century Dictionary.
- noun A vessel, usually a cylinder with curved ends, for collecting the steam from a boiler. Such a receptacle is almost always used on a water-tube boiler to permit a sufficient volume of steam to be accumulated so that the pressure will not fluctuate as steam is taken intermittently by the engine.
- noun A pipe or cylinder on top of or above a steam-boiler and connected thereto by a short neck, serving as a dome to allow the flow of steam from the water to be slow enough therein to permit entrained water to settle at the bottom and be drained back.
