The ver-tical marine engine may sometimes be altered into thecompound form by placing the new cylinder above the oldand the two pistons on a common rod. The straight-line engine.—Since the first introduc-tion of this engine in 1880 there have frequently been madeimprovements in the details of construction and two im-portant changes in steam-distribution. In the use of constant lead and the specially devisedvalve-motion to accomplish it, it was discovered that a con-stant lead was not a
