About saving coal and using steam in a simple way with steam engines Drifting up to a very high point, the inventors did the in enclosed Drawing schematically represented steam engine constructed.

I is the small, II the larger cylinder of a Wo ο If'sehen machine with an intermediate one Slide for both cylinders.

Cylinder III, which is larger than II, is the smaller and IV the larger cylinder of a second Woolf's machine with the former similar slide located between the two cylinders III and IV. I and II are surrounded by a steam collector X (receiver), which can be heated in a known manner by direct steam or outgoing fire gases, which is not shown any further. All four cylinders can be provided with a steam jacket. The cranks of the cylinders I and II, and of III and IV are opposite to each other, and the first pair are offset by 90 ⁰ to those of the second pair, as shown in Fig. 3 sketched.

The vapor α enters I at a ^1. The exhaust steam leaves I at b ^l and enters II at a ² , while the exhaust steam from II exits at έ ² and enters receiver X. From here he goes at a ^s to III. The exhaust steam verläfst III at b ^z and occurs in a ^l to IV. The exhaust steam from IV verläfst this cylinder by <5 ⁴ and goes to the outside or in the condenser, event, yet the distiller pass irend. These latter two apparatus are not indicated in the drawing.

The four cylinders therefore represent two Woolf machine pairs, whose cylinder II and III are connected according to the compound principle and where only the smallest cylinder I receives fresh steam, namely high tension (of approx. 6 atmospheres and more), while the remaining cylinders II, III and IV always receive the exhaust steam of the previous one.

This construction can be extended by using three pairs of Woolf cylinders two receivers arranged between the first and second and the second and third pair will. The cranks of each pair are opposite or above each other and are to those of the next pair 12o ° or 60 ° offset, as in the sketch indicated by FIG. Of course, the steam has to be even higher right from the start Have tension (about ι ο atmospheres and more) than when using only two pairs Cylinders.

The arrangement of the slides is shown differently in the drawing to show that any suitable arrangement can be used. A well-known mussel slide is drawn between III and IV. Between I and II a new slide S with a trapezoidal cross-section is shown, which is to be preferred since the friction on the slide surfaces can be reduced to a minimum by passing it through

Wedges resp. Adjusting screws and strips can be precisely adjusted.

Claims (1)

Patent-to sayings: i. A steam engine with two or more Cylinder pairs I II, III IV and so on, which at the same time have the following characteristics having: a) only the smallest cylinder I receives fresh steam; the second, larger one Cylinder II receives the exhaust steam from the first, the third, again larger cylinder ΙΠ the exhaust steam from the second u. s. w .; b) between cylinders II and III, IV and V etc. a possibly heatable receiver is switched on;
c) the two cranks of each cylinder pair I and II, III and IV etc. form an angle of 180 ° or ⁰ ° with each other, while the cranks of the pairs with two pairs by 90 °, with three pairs by 60 ° respectively. I2o ° etc. are offset from one another. The application of a multi-cylinder compound steam engine of this type Slide between the two cylinders I and II, III and IV and so on each one Couple. For this purpose ι sheet of drawings.
