To all whom it may concern.-

Be it known that I, FRANK J. LIESKE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan,

5 have invented a certain new r 11d useful Improvement in Submarines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertalns to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to submarines, and its object is a. submarine so arranged as to 15 allow the inmates thereof to escape ln case of the submarine sinking. Another object of the invention is a main submarine proyidcd with a slip at the rear end adapted to receive a completeauxilia'ry submarine. An

additional object of the invention is an auxiliary submarine provided with means for securing it in the slip in the main submarine, the device being so arranged as to not change the general outline of the main submarine. These and other objects and the several novel features of theinvention in its preferred form are hereinafter more fully described and claimed and shown in the accompanying drawings in which' Figure 1 is an elevation of a submarine embodying my invention.

Fig. 2 is a longitudinal section thereof.

the auxiliary submarine .from movement within the main submarine. I

Similar characters refer to similar parts throughout the drawings and specification. 5 The main submarine as shown in Fig. 1 is of the well known type, and isprovided with the usual periscope 1 and conning tower 2 which gives access to and from the main submarine. At the forward end the submarine is provided with torpedo tubes 3 and torpedoes therefor as is the usual practice. While the boat maybe driven by any of the several well known mechanisms, I have shown an internal combustion engine 4. which propels the boat and generates electricity by means of the generator 5. Tanks 6 are placed at desirable points within thehull of the main i submarine and are adapted to 'be filled with water,for submerging the main submarine 70. or by expelling the water from the tanks the submarine is made to rise;

The auxiliary submarine 8 which is carried by the main submarine is also provided with a means of propulsion (an internal combustion engine being shown), and is provided with a tube 9 at the forward end thereof which is of suific-ient size to receive a torpedo and is used as an entrance to the auxiliary submarine, the auxiliary submarine being shown more particularly in Figs.

3 and lVhile I have shown the auxiliary submarine as used with a main submarine it may also be used in connection with a freight boat or 'a'rship or other boat in conjunction with which a small submarine is useful. This auxiliary submarine is provided with water tight portlights 10' and a miniature model of the main submarine, being provided with submerging' tanks and other ap- '90 purtenanccs of the larger boat (though not hereshown). As will be seen more particularly in Fig. 2, the auxiliary submarine is adapted to fit tightly in the slip 11 of the main submarine, the tube 9 thereon fitting n aperture therefor in the main submarine and the joint between the main and auxiliarysubmarines being packed to prevent It will also be seen when the auxiliary sulmiarine is settingmines or 1 disconnected from the main submarine water would flow into the main submarine through moves into the slip 11 and a hookedengag mg member 15 which protrudes as shown in dotted lines in Fig. 3, engages over thehook nuuuber 16 of 'the main submarine.

The auxiliary submarine is drawn forward in the slip 11 by means ofthe mechanism shown in the auxiliary submarine and which consists of a motor 17 adapted to drive the shaft 18 through the belt 19 and thus turn the gear 20 on the shaft 18, the gear 20 being in mesh with the gear 21 threaded on the shaft 22 of the hooked engaging member 15. This gear 21 thus acts as a nut and as it is turned the auxiliary. submarine is drawn forward until the nose 9- engages tightly in the aperture therefor in the main submarine at which time the hooked engaging member 15 has been drawn up and assumes the position shown in full lines in Figs. 2, 3 and 4. To keep the shaft 22 and engaging member 15 from turning with the ear 21 a keyway is provided in the said time as is shown in Fig. 6. Itcan thus be seen that by placing a suitable key in the keyway the shaft is held from rotation and the engaging member is held in proper alinement. As will be noted more particularly in Fig. 3 the auxiliary submarine is providedyvith a flange 23 thereon having undercut lugs 24. The method of under-cutting the lugs is shown more particularly in Fig. -7. The main submarine is provided with lugs 25 thereon having hooked ends adapted to engage under the lugs 24 of the auxiliary submarine. The keel of the auxiliary submarine shown in Fig. 3 is provided with lugs 26 thereon which are adapted to engage under similar lugs 27 on the main submarine in the same manner as the lugs 2-1- and 25 engage. 'As is shown more particularly in Fig. 9, as the auxiliary submarine settles into the slip on the main submarine, the undercut lugs 2i move-in between the lugs 25 on the main submarine, and as the auxiliary submarine is drawn forward the lugs 24 and 25 engage and prevent movement of the auxiliary submarine in relation to the main submarine. The lugs 26 on the heel of the auxiliary submarine are adapted to operate in the same manner, the lugs 26 passing between the lugs 27 as the auxiliary submarine settles into the slip 11 on the main submarine, and as the auxiliary submarine is drawn forward 1n the shp 11 the lugs 26 engage beneath the lugs 27 and tend to further prevent motion. of the auxiliary well known character of construction. by

means of which the auxiliary, upon longitudinal movement into the slip, may be locked from vertical movement therein; i

It is to be understood thatthe auxiliary submarine moves into the slip 11 on the main submarine in the same manner as a ferry boat moves into its slip and the main submarine can be moved about to receive the auxiliary submarine by the vertical and horizontal propel1ers30 and 31 which may be used to raise or lower the rear end of the main submarine or turn it about on a pivot. The novel features of this invention exist in providing the well known type of sub marine with a life boat which gives the passengers on thesubmarine anopportunity of escaping if the main submarine is disabled an enemy shell or by accident. For instance, ifthe main submarine is struck by a shell and sinks, the passengers of the main submarine may withdraw the closure 12 should the closure be in closed position, from the nose9 of the auxiliary submarine by turning the hand wheel 13 and the passengers or crew would then open the water tight door 28 of the auxiliary submarine. and pass into the interior thereof. The water tight door 28 may then be closed and the motor 17 set into operation forcin the auxiliary submarine backward and 1sen-. gaging the lugs 24 and 25 at the sides of the auxiliary submarine. disengage the lugs 26 and 27 on the keel thereof, whereupon by exhausting the water from the tanks of the auxiliary submarine, (not here shown) the auxiliary submarine will float free from the main submarine and can then be guided toany point at will, for instance, the auxiliary submarine could then by use of the torpedo and tube 9 sink the ship which blew up the main submarine.

The auxiliary submarine may also be used .for laying mines as. it can beopera'ted more easily than the main submarine, and the auxiliary submarine may use the main submarine as a base and do scouting work and This will also tion,'its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is 1.
