To all whom it may concern y Beit known that I, VIRGINIO CAyaLLINr, a subject of the King of italy, residing at Spezimin the Kingdomroit italy, have in Vented certain new and useful improvements in Hulls. for Submarine Boats, of which the following is a specification. Y

The hull for submarine boats accordin to the present -invention has` for its object, on the one hand, to secure complete separation of the storage batteries, and on the other hand to render the liteV turret accessible by two diderent passages. ln the hull are formed tour independent compartments,

one of them being exclusively designed for receiving the storage batteries.

in the annexed drawing is represented of them are the compartments -awhich -i receive the water ballast, the inner compartment -bbetween the aforesaid two compartments, is -or the crew and which contains all the' propelling and operating machinery .of the submarine boat, the compartment -c, which forms the special feature of the present invention, is designed exclusively to house' the storage batteries. -The partltion -fwhich separates the com partment -ofrom the contiguous rooms, is strongly buiit so as to be able to resist a high water-pressure; In this manner even in the' case ot the huit being damaged by reason. et receiving shocks, or running aground, or in consequence ot any other enternal casualty, the noxious ases, 'which may discharge from. the accuinu ators, owing to the sea water having @coded the interior of the boat, wiltV remain oonned in the compartment -cwhich, as already stated, is separated trein the dwelling rooms of .the hull by partitions capable of resistingvery great pressure. it necessary, the compartment -cmay be further subdivided into a certain number ci"i sinailer cornartrnents separated by strong watertight nlhheads provided with communicating by way ot example an embodiment of the pres?v vent invention.

doors, so as to keep separatev the various storage batteries, and to reduce atthe same time, to a minimum, the space susceptible of being flooded in case of damage. As shown by the cross sections, thelstructure of the hull in the compartment om is designed so as to allow of thestorage batteries being placed on the right hand side, and on the left hand side, of the hull, leaving free a middle s gang way eef running llilil'pugh practically thewhole length of the At the ends of the compartment .--cthere is provided twosmallhatchwaysf-dwithV watertight closures, which put the lower compartment of the hull into communication with the inner upper compartment --b-1 occupied by the crew. The cen tral portion 'of the submarine boat'and the upper portion is provided with a turret -g capable of containing the whole crew. This turret, by means of the ports -p and -Q-, may communicate with two of the smaller partitions of the inner' upper compartment of the hull and may be detached so that the crew can reach the surface of the sea in case of accident.

The turret '-g-, and the lower compartment -c-, with its passage -e-, forms a combination, which in most .cases allows a crew, distributed at the bow and at the stern ofthe inner compartment -b,- to all' gather in one of lthe two compartments communicating with the life turret, to enter the turret itself, and Ito reach the surface of the sea.

The lite turret rests upon the upper por-I tion of the hull and is connectedl with it by means. of two entrance ports -p-- and -f-gw and a double lock nfwhich enters into two sockets fixed on the lates -c-, rigidly connected with the hu The two locks are connected by a double threaded nut --t-. After having disengaged the two ports -;0- and -g-, from their bolts connecting them with the hull, the turret may be detached by simply turning the nut -z-.

'lihe working ot this device is as follows: Should the boat sink, or any mechanism oi it fail to work properly, all of the men assemble in the compartment -c.-, availing themselves also ci the longitudinal passage ecand from there they pass .into the turret which is then detached and set adoat.

',"ihe device according to the present in vention maybe applied to any submarine l hull, as it is based on a principle which is dependent upon the shape of thefboat.

.Having now, fully described and ascervtained the nature of the said invention and a compartment for the crew, two lateral compartments for- Water baliastand a compartment `disposed beneath the tbreeiirst named compartmentsand designed to receive storage batterie@ said last named compartment having a longitudinal passage and tWo ports provided at the ends of said pase sage and communicating with the compartment of the crew, and two ports provided in the crews compartment and communicating With the life turret.

In testimony whereof I ax mysignature in the presence of two Witnesses.
