label: Description
content: The engine has four single-acting, horizontal cylinders arranged in a block like the chambers of a revolver. Connecting rods form the four pistons connect to pins on crank disks on a common shaft. The head ends of the four cylinders open into a drum-like exhaust chamber. A rotary valve of peculiar construction revolves in the exhaust chamber close to the ends of the cylinders and opens the cylinders to the exhaust chamber or to the pressure inlet pipe, which forms the hollow stem of the valve, in proper sequence. The hollow stem of the valve passes out of the forward side of the exhaust chamber through a gland and bearing. It carries a spur gear that meshes with a pinion on a lay shaft, which parallels the cylinders and is turned by a bevel gear pair at the crankshaft.
