To all whom it may concern 1 Be it known that we, QOXRAI) REGEN- Bo EN and H'ANS VoGnL, citizens of the German Empire, residing at Kiel-Gaarden, Germany, and Kiel, Germany, have invented certain new and useful Improvements in Submarine Boats, of which'the following is 1 a specification. A

The present invention relates to submarine boats Which are driven by a steam engine during surface travel, but by an electric motor when under water, and itresides primarily therein that the blasting plant ior generating the Combustion pressure air for the boiler combustion is arranged outs1de of the pressure proof body of the boat.

"In the accompanying drawing, one ear bodiment of the invention has been illustrated, and the figure shows a vertical longitudinal section through the boiler chamber, as Well as portions-of the adjacent chambers of a submarineboat of the above described kind.

1A; represents the pressure proof body of '25 .structed as a superstructure which can be the" submarine boat and B a platform conflodd hen the boat dives down. 'fiWith the boat is formed a boiler room (3' the bulk heads a a, and this room is reached by means of bulk head doors, not shown. In the, room C a Water tube boiler D, preferably an oil burning boiler, is inserted which generates the necessarysteam for driving a steam engine, not shown. This boileris connected with'a smoke stack E which penetrates through the pressure prooi body A of the submarine boat, and the external portion thereof reaching above the platform is constructed to be laid down as represented by dot and dash lines during submarine travel. The opening of the Y, smoke stack may be closed watertight "through a lid N, by means of a hand wheel n from the.1nom P steam'turbine G. The suction pipe H of the adjacent to the boiler room.

In the superstructure B, that is, outside or the pressureproof body A of the boat, is

now, in accordance with the present invention, the blasting plant inserted this plant consisting of-a ventilator F and a driving ventilator F opens outwardly, while-the 1 pressure pipe"-K penetrates through the pressure proof body A id the boiler room G and s;

of the hoat 'outside re 11 Through the assistance of a hand wheel 3, the pressure pipe K mavlbe closed water tight from the"; om R through a closing valve L. starting and stopping "ofthe driving tur through the bulk head a into the boiler .From the same roo'inzthe.

bine G for the ventilator F may also be opother in a suitable manner through a pas- 1 sage, ago-"inst the boiler room.

During surface travel, the parts have the position shown by full lines in the figure, that is the smoke stack E stands erect. the valve L is open and the steam valve N set for running. marine boat then takes place through the steam engine fed from the boiler'D the blasting F G being in operation; If the boat is going to dive down, the boiler fire is put out and the ventilator F stopped through the closing of the steam valve M. Thereupon the valve L is closed tightly by turning the hand wheel P, the smoke stack E is laid down and the smoke stack lid N closed by means of the hand wheel n The driving of the boat now takes place in awell known manner through an electric n1otor, not shown, fed from an accumulator battery. 1 fit-er the rising of the boat, "-a teniperature will exist in the boiler room. (1, in accordance with experience, when the boat has been under water for a great length of time, which does not permit of entering the room without danger. By means of the described device it is now possible to open the lid N, to raise the smoke stack E, to unscrew the valve L and start the blasting plant F G from the adjacent rooms 1 and B. After a-short time the room C will besuflicientlycool so that it may be entered and the steam boiler againstarted for surface travel.

The arrangement of the blasting plant' outside of the pressure proof body of the not shown. which may be closed submarine boat provides a considerable ad vantage in that th'is'body of the boat is this case'not'penetrated by the large sucbut only by the small pressure the v ventilator F. The pressure The propulsion of the subroe proof body of the boat will therefore be less weakened and the closingvalve L receives a smaller diameter which is very essential for a tight closing. Still another advantage is attained by passing the pressure pipe K through the pressure proof body A of the boat outside of the boiler room C, as at this place a complete tightening of the joint is possible at the point of penetration, because the portion of the body of the boat situated outside the boiler room will show a more uniform temperature than the portion thereof situated Within the boiler room C which is exposed to considerable heat expansion and contraction in consequence of the different temperatures that occur therein, so that the tightening of the joints at the place of penetration is made very diflicult.

We claim 1. In a submarine boat provided with a steam engine, a blasting plant for generating the combustion pressure air for the boiler, said blasting plant being situated Igutside of the pressure proof body of the oat.

2. In a submarine boat provided with a [steam engine, and a pressure proof body, a blasting plant outside of said pressure proof body, a plurality of bulk heads with- -in said body forming a water tight steam boiler room and separate operating rooms, a pressure pipe for the blasting plant through said pressure proof body into one of said operating rooms and from there through one of said bulk heads into said boiler rooml 3. In a submarine boat provided with a steam engine, and a pressure proof body, a blasting plant outside of said oresi' ire proof body, a plurality of bulk heals w thin said body forming a water tight ates. boiler room and separate operating res-ms a pressure pipe for the blasting plant leading through said pressure proof body into one of said operating rooms and from there through one of said bulk heads into said boiler room, said boiler having a. smoke stack penetrating through said "pressure proof body, and means for closing said smoke stack, said means being actuated from within one of said operating rooms.

4L In a submarine boat provided with a steam engine, and a pressure proof body, a blasting plantou'tsideof said pressure proof body, a plurality of bulk heads Within said body forming a watertight steam boiler room and separate operating rooms, a pressure pipe for the blasting plant leading through said pressure proof body into one of said operating rooms andfrom there through one of said bulk heads into said boiler room, and means for closing said pressure pipe, said means being'actuate'd from one of said operating rooms.

In testimony whereof the foregoing specification is signed in the presence of. two witnesses.
