Steam Cylinder

Sectional View of Steam Cylinder

sand mold and bored to a true circle; all ports and passages for live and exhaust steam are of ample size to give a minimum frictional resistance. The steam distribution is regulated by a Meyer adjustable valve gear, having a wide range of action, the adjustment being easily and quickly made by a hand wheel, even when the machine is in motion. The cylinder drain cocks are of a special pattern and can be opened or closed like an ordinary globe valve, but which will automatically open under an excess of pressure due to water in the cylinder.
