(01. 121-102) This invention relates to a multiple-expansion a diameter of 970 mm. which is, however, so large Piston steam engine provided with a speedthat it is practically out of the question to build change gearing between the crank shaft of the such an engine. But if, according to this inhigh-pressure stage and a crank shaft of a lower vention, 800 revolutions per minute are used in 5 stage. With a known engine of this type a spurthe low-pressure stage, the diameter of the low- 5 wheel gearing is inserted between two crank pressure cylinder will amount to only 485 mm. shafts lying side by side. In contradistinction which is a very acceptable size for this cylinder. thereto the crank shafts are, in the present in- In the modification shown in Fig. 3 all three vention, arranged in a line and are connected crank shafts rotate with different speeds of with one another by planet-gearings having a revolution. Between the shaftB of the high- 19 corresponding ratio, whereby it is rendered pospressure stage and the shaft'9 of the mediumsible to arrange the engine upon a frame of the pressure stage is inserted the planet-Wheel gearusual construction. iii, and between said shaft 9 and the shaft The invention is illustrated diagrammatically ii of the low-pressure stage is inserted the and by way of example on the accompanying planet-wheel gearing 3. The low-pressure stage'l drawing on which is shown aconstructional form is divided into two low- pressure cylinders 3, 3. of an engine designed according to this invention It is assumed that the planet-wheel gearings l0, and on which Figure 1 is a front View of the i3 have a ratio of 1:1.5: 2.
