To all whom it may concern:
Be it known that I, KARL Scrum), manufacturer, subject of the Emperor of Germany, residing at Landsberg-on the-Warthe, Germany, have invented certain new and useful Improvements inSingle-Acting, Condensing, Continuous- Current Steam Engines, of which the following is a specification.
The present invention relates to a singleacting condensing continuous currentstearn engine, and in particular to engines of this kind of a vertical type, as they are chiefly used as marine engines, for drivingdynamos and the like purposes. The object of the present invention is'toprovide as compact a design as possible, to avoid all piping between engine and condenser and to prevent that the condensate, which is produced, chiefly in starting penetrates into the crank casing and there, when immersion -lubrication 15 employed, saponifies the oil, whereb also the danger exists that the mixture of Oll and condensate "gets into the exhaust passage, soils the condenser and renders the condensate unsuitable for feeding the boiler.
This object is obtained, as far as multiple c linder sets are concerned, essentiall b t e arrangement that the exhausts of al cy inders open into a common condenser chamber, by't e engine frame serving at the same timeas condenser casing actin as connection between the cylinders. on this arrangement is provided with continuous current steam engines with closed and evacuated crank casing the entrance of the condensate intothe latter is prevented by the piston being stepped and working with its two steps in a non-continuous, likewise stepped cylinder, whereby the upper end of the smaller cylinder pro ecting mto the exhaust chamber is encircled cup-like not only by the lower end of the larger cylinder projecting into the same chamber but also by the larger end of the piston itself.
In the accompanying drawing a constructional form of the present invention is exem lified.-
igiure 1 is a vertical section through one cylin er of a single acting continuous current steam engine. 7
inder engine shown Fig. 2 is the upper portion of a four cylpartly in section, seen fromone side.
Fig. 3 is a diagram in a reduced scale, of the plan ofa four cylinder engine, the dot: and-dash line 11-11 indicating the line on which the section in Fig. 2 is made.
And Fig. 4 is a part of a view similar to Fig. 1 of a modified form of condenser chamber provided with spray cooling.
The frame a of the engine is constructed in its upper part in form of a condenser chamber b, which, in case of a surface condenser is fittedwith cooling pipes c throu h which the cooling medium travels in the irection indicated by the arrows. It is obvious that the condenser may also be con-. structed as injection condenser in which case injectors, sprays or the like would be substituted for the cooling pipes a, (see Fi 4).
The cylinders d,wh 1ch are made in orm of ordinary flanged tubes, project with their lower edge e so far into the condenser chamber, that the upper edge 7 of each piston, when the latter is in its lowermost osition, enters into the condenser chamber. he cyl-= inders d are secured to the condenser chamber b by means of their flanges only, so that the cylinders can expand fr y without any trouble being caused thereby. In the lower part the cylinders communicate with the condenser chamber, several rows of bores being arranged in the resent exemplifies.- tion over each other, the said bores h arranged at an angle to the axis of the cylinder which is favorable to the impinging on the cooling surfaces. tive exhaust angle, the communications be- For avoiding an inefieotween cylinder and condenser may be bored wholly or partly at right angles to the axis of the cylinder immediately a ove the piston when in its lowermost position.
Therpistons i are made as step ed plungers and are guided in cylindric guides k which are disposed partly in the engine frame a, partly in the condenser 12. The upper edge I of the cylindrical ides k projects for some distance into t e lower end of the, corresponding cylinder dand the up-' per part of the piston 71 is made at m in form of a cuif, so that when the piston is in its lowermost position the upper edge Z of the guide It is overlapped by the head of the. piston as seen in Fig. 1. The consequence of such arra ement is, that the condensate,
. which accum ates either at the lower edge e oi the cylinder or at the lower edge of the denser or into the exhaust chamber, while the working surfaces between the lower art of the piston 11 and the cylindrical gui e k is not reached by the condensate, andthe latter can neither penetrate into the crank casing n closed all around and serving as oil vessel, and preferably evacuated.
All other parts of the engine have no relation to the subject matter of the present invention and have, .for such reason, been.
either quite omitted or have been onl dia grammatically shown and shall not described any, further.
I claim: 7
1. A single-acting condensing steam engine, comprising a condensing chamber, a working cylinder and a coaxial guiding cylinder extending into said condensing chamber from opposite sides thereof with open inner ends separated from each other; a

cylinder when the working cylinder is exhausting.
2. A single-acting condensing steam engine, comprising a condensing chamber, a working cylinder and acoaxial guiding cylinder extending into-said condensing chamher from opposite sides-thereof with open inner ends separated from each other; a working piston fitted to said working cylinder, and a rigidly united guidin piston WOrking cylinder having ex aust ports leading into the condensing chamber and said worki piston having a longitudinall extended 0% which surrounds the end of a guiding cylinder'when the working cylinder is exhausti'n the workin cylinder being of lar r iameter than t e (guidin cylinder, an the open ends of sai cylin ers bein longitudinally overlapped, so that the cu on the workln piston remains withinthe working cylin er when surrounding the end. of the guiding cylinder.
3. A single-acting condensing steam en- .engme, comprising a common condensing chamber, a series of single-actingworking cylinders all having open inner ends proecting into the common condensing chamber and constructed with exhaust ports com- .municating with said chamber, a coaxial guiding cylinder for each working cylinder,
each having an open inner end projectinginto the condensing chamber from the side opposite to its working cylinder, and each being of smaller diameter than and telescopmg partially with its working cylinder, an a working piston for each w'orkmg cylinder, having a rigidly united guiding piston fitted to the corresponding guiding cyl inder; each working piston being constructed with a longitudinally projecting cufi' in position to surround the end of the guiding cylinder when the working piston is in the exhaust position.
