Not illustrated. 1894 Excerpt: ... be seen that almost the whole of the compressed air remains in the valve chambers (see Fig. 3, Plate II.). During the return stroke of pistons 2 and 3, the air passes from these chambers into the cylinders, in the proper direction to meet and mingle with the coal dust as it falls. The heat is thus equally distributed through the whole quantity of air, the volume of which is very small. Of all the parts of the engine, the rotating disc H alone is directly exposed to the flame, but as it is not a tight-fitting valve, this is of little importance. Besides, it is so constructed that it can be easily and quickly replaced. External Valve Gear. From this description it is evident that all the valves, with the exception of valve V4, are opened or closed only at the end of the strokes of their respective pistons. This greatly simplifies the mechanism, as great precision is not required, because the speed of the pistons at the end of the stroke is zero. Cams have therefore been chosen for raising all the valves, and springs for closing them, as in Sulzer steam engines. The transmission of the motion from the cams to the valves, through rods, bell cranks, &c., is also similar to the Sulzer valve gear. As will be seen from Plate II., especially Fig. 7, all the cams are upon one horizontal valve shaft, placed behind the three cylinders (shown in plan, Fig. 8), which also drives the helical gearing working the coal distributor. It receives its motion from the vertical shaft W, driven in its turn by a pair of helical wheels from the main crank shaft. The valve shaft only makes half as many revolutions as the crank shaft. The construction of the engine is such that each valve, taken separately, is only set in motion at every second revolution of the motor, with the ex...
