“The shaft, where it passes through the diaphragm, is fitted to a bronze bushing with a few thousandths of an inch clearance. This bushing seats on the metal surface of the diaphragm with latitude for slight side motion. It is kept to its seat by the steam pressure, but can move sideways to accommodate any whipping motion of the shaft.” —Derr, 1911
