NOVEL TRIPLE COMPOUND MARINE novel features are the three-part eccentric oscillating upon the. crank pin and upon each of which a strap fixed to the piston rod ofeach cylinder slides in ways parallel with each piston rod. The throwof eccentrics and crank are each equal to one-half the piston eccentrics are at 90° and 180°, as shown at a. The three pistonvalves are directly connected by rods to thin straps on an angularlymounted cylinder that slides on the shaft by the hand lever for for-ward, stop, or reverse motion. Piston valves are used, taking the steam in the middle and exhaust-ing at the ends. The steam passes from the first valve, through thetriangular space between the cylinders, to the next valve chest. 162. Vertical section through intermediate cylinder.
