EXPLOSIVE-ENGINE.
SPECIFICATION forming part of Letters Patent No. 705,022, dated July 22, 1902. Application led November 24, 1900. Serial No. 37,652. (No model.)
To all whom it may concern:
Be it known that LWILHELM BERNHARDT,a subject of the Emperor of Austria-I-Iungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Explosive-Engines3 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichl it appertains to make and use the same, reference being had to the accompanying draw ings, and to letters of reference marked thercon, which form a part of this specification.
The present invention relates to certain improvements in explosive-engines, the object of which is to diminish the quantity of water required for the cooling ofthe motorcylinder. For this purpose the exhaustgases from the motor, are discharged in the shape of a jet through a tube terminating in a noa/ile into a tube communicating with the receptacle oontainin g the cooling-water. The suction produced by this jet induces a iiow of air through the receptacle, said air passing over the surface of the cooling-water,and thus refrigerating the same. i
The accompanying drawings represent in Figures l and 2 the arrangement of the device according to this invention in two sectional views.
It is a well-known fact that in explosiveengines the cooling of the cylinder requires a considerable quantity of cooling-water, which in stationary engines is mostly supplied by a separate pump actuated by the motor. This circumstance-ic., the great quantity of cooling-water required-constitutes a serious drawback in explosive-motors, particularly in the case of portable engines, which are intended for field work and mostly have to carry with them their supply of coolingwater. To obviate this inconvenience, the additional pressure of the exhaust-gases over the atmospheric pressure, which is not utilised in the cylinder, is employed, according to the present invention, for lowering the temperature of cooling-water. This is effected as follows: As will be seen from the accompanying drawings, the engine-cylinder u is surrounded bya receptacle b for the cooln ing-water, this receptacle being not quite full of water and communicating with the atmosphere by means of two tubes c and cl. The exhaustgases are caused to pass through a pipe finto an exhaust-chamber g and from the latter through a tube h, terminating in a'nozzle, into the tube c. The gases escaping from the nozzle withgreat rapidity in the shape of a jet induce a flow of air from the receptacle b and cause it to pass through the tube c. As fresh air from the outside constantly enters through the tube d, a permanent air-current is thus generated,which produces an intense cooling of the water.
It is very important to give the exhaust chamber g a comparatively great capacity, as otherwise the discharge of the waste gases would take place by jerks. As will be seen from the drawings, this is effected by making the exhaust-chamber the connecting-piece vbetween the axles and the body of the carriage. l
In order to obtain a continuous supply of fresh water into the'cooling-water receptacle l) in the measure as the water contained thereinV has evaporated, the following arrangement is provided:
p The receptacle h for cooling-water is con nected, by means of a pipe fi, with an open reservoir 7c, arranged on the rear part of the engine and in which is rotatablyl mounted a receptacle m, closed on all sides, provided with a filling-aperture Z, and preferably made of cylindrical shape. This receptacle is completely filled with water, and bythe rotation of the crank n it is turned so far as to bring the filling-opening Z in its lowermost position.
The'water from the receptable m' is discharged successively, so that the water-level in the reservoir 7s permanently remains more or less on the level of the filling-aperture Z, because as soon as the water-level rises above this aperture the atmospheric pressure prevents a further outflow of the water from receptacle m. By this birds-fo-untain arrange=- ment the water-level in the receptacle h for the coolingwater is also maintained constantly on the same level.
I claim l. In a gas-engine, the combination with the cylinder, of a chamber containing cooling liquid surrounding the same, an air inlet and outlet to said chamber both above the level IOO of the liquid therein, and an exhaust-pipe from the engine arranged to exhaust gas into said air-outlet and thereby induce a current of air over the surface of the cooling liquid, substantially as described.
2. In a gas-engine, the combination with the cylinder, of a chamber containing liquid surrounding the same, an air-inlet to said chamber above the level of the liquid therein, and an injector connected to the chamber and operated by exhaust-gases from the cyl-v inder, whereby a current of air is created across the surface of the liquid in said chamber, substantially as described.
3. In a gas-engine, the combination with the cylinder, a chamber containing a cooling liquid surrounding the same, air inlet and outlet pipes for said cooling-chamber both above the level of the liquid therein, of an eX- haust-chamber connected with the exhaust- Valve, and an exhaust-pipe leading from said exhaust-chamber and leading into the airoutlet pipe of saidchamber, substantially as described.
4. In a gas-engine, the combination with the cylinder, of achamber containing a cooling liquid surrounding the same and provided with an air-space above the liquid, an air-inlet at one end and an air-outlet at the opposite end of said cooling-chamber, an exhaustchamber, a pipe connecting the cylinder With the exhaust-chamber, and a pipe leading from the exhaust-chamber and terminating in the outlet-pipe, substantially as and for the purpose specified.
5. In a gas-engine, the combination with the cylinder, of a chamber containing a cooling liquid surrounding said cylinder and provided with an air-space above the liquid, means for automatically supplying said liquid to the chamber, an air-inlet mounted in one end ot' said cooling-chamber above the air-space, and an air-outlet mounted in the opposite end of said chamber, an exhaustchamber, a pipe leading from the cylinder to the bottom of the exhaust-chamber, and a pipe leading from the top of said exhaustchamber and terminating in the air-outlet, substantially as and for the purpose specified.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
