SUBMARINE BOAT.

Specification of Letters Patent.

Application filed April 13, 1915. Serial No. 21,036.

To all whom it may concern:

Be it known that I, JOSEPH BARRAJA- FRAUENFELDER, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Submarine Boats, of which the following is a specification.

The invention relates to improvements in submarine or submersible boats, and particularly to the construction and arrangement of boiler-rooms for such class of boats such as that shown and described in United States Letters Patent granted to me April 6, 1915, No. 1,134,940, and assigned to The Lake Torpedo Boat Company of Maine.

The object of the invention is to provide an arrangement to permit communication between the forward and after ends of the boat when the boiler-room is closed without necessitating passage through the boilerroom, to thus not only prevent the highly heated air of the boiler-room from escaping into the working or living compartments of the boat through the opening of the doors leading intothe boiler-room, but also to avoid the discomfort and danger incident to passing through the highly heated air contained within the room when the ventilators thereof are closed.

The invention consists in arranging a compartment within the main hull of the boat, providing a boiler-room of such size so as to provide a chamber around and at the ends of the compartment or boiler-room, said chamber providing a water-jacket which is designed to be filled with water from the surrounding body of water when the boat is submerged, or an insulating air space or jacket when the said chamber is empty of water; in the construction of air locks at the ends of the compartment, and in the arrangement of a passageway between said air-locks; the arrangement being such to'permit one to pass from one end of the boat to the other without passing through the boiler-room when the doors leading thereto are closed, to thus prevent the heat within the boiler-room from escap ing into the working or living compartments of the boat.

The invention further consists in details of construction and arrangement of parts as will be hereinafter fully described.

In the drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a diagrammatic vertical longitudinal section of the amidships portion of a submarine or submersible boat. Fig. 2 is a horizontal section of the same drawn on the line a-w of Fig. 1. Fig. 3 is a transverse section on a larger scale drawn on'the line 6-?) of Fig. 1. Fig. 4 is a similar view drawn on the line c0 of Fig. 1. Fig. 5 is a similar view to Fig. 4 illustrating a slightly different form of passageway connecting the airlocks. Fig. 6 is a detail horizontal section drawn on a larger scale on the line d-d of Fig. 1.

1 designates the main hull of a submarine or submersible boat of any improved design, in the present illustration shown clrcular in cross section, and as is usual, is constructed of ribs or frames 1 and shell plating 1". Within the hull and preferably at amidships, is arranged a compartment 2, providing a boiler-room substantially cylindrical in cross section, said compartment having its ends closed by bulkheads 3 which are connected airand water-tight to the ends of said compartment, and to the plating or ribs of the main hull l as shown, the bulkheads being provided with doorways or openings 4 leading into the boiler-room which are controlled by inwardly opening doors 5. Spaced from the bulkheads 3 are bulkheads 6, having their edges connected airand water-tight to the shell plating or ribs of the main hull 1, and these bulkheads 6 are also provided with doorways or openings 7 controlled by outwardly opening doors 8. In the spaces thus formed between the bulkheads are arranged substantially U- shaped frames 9, having their forward and rear edges connected airand water-tight to the

respective bulkheads

3 and 6, and their lower edges connected to the plating of the main hull 1, thus providing air-tight compartments or vertical passages 10, which I shall hereafter refer to as air-locks. In the space thus formed below the boiler-room 2 and the skin of the main hull 1, is arranged longitudinal partitions 11 providing a longitudinal passageway 12, said partitions 11 having their upper and lower edges connected airand water-tight to the bottom of the boiler-room and to the plating of the Patented Nov. 2, 1915.

main hull respectively, and their ends likewise connected to the bulkheads 3. The said bulkheads are provided with doorways or openings 13 establishing communication between said passageways 12 and said airlocks 10, the said openings 13 being controlled by doors let opening within said airlocks. Vithin the air-locks 10, immediately below the

openings

1 and 7, are arranged arched top 16. In either construction, however, it will be noted the partitions 11, pro vide longitudinal supporting girders for the boiler-room 2.

Like the construction shown in my aforesaid application, the space 2 around the boiler-room and the spaces 2 at the ends thereof, are designed to be filled with water when the boat is operating submerged, or in a semi-submerged condition, and thus form a water-jacket around the boiler-room, whereby to confine the highly heated air to the boiler-room.

The partitions or bulkheads 3 are provided with openings 3' Fig. 3, to permit free circulation of water between the spaces 2' and 2". Any suitable means may be provided for controlling the inlet and expulsion of water to and from the

spaces

2 and 2", but as this feature forms no part of the present invention, it is not thought necessary to illustrate or describe the same. I do not wish to be limited to the construction of admitting water to the space 2 as it will be obvious that the openings 3 in the bulk heads 3 may be dispensed with and the said spaces 2 thus converted into air-chambers, or air-locks when the doors controlling the openings in the bulkheads are closed. When the chambers or spaces 2 are used as airlooks, it will be understood that the frames 9 may be dispensed with.

The boiler-room will be supported within the main hull intermediate its ends by suitable struts (not shown), but as this detail will be well understood by anyone skilled in the art to which the invention relates, it is not thought necessary to show it.

In operation, when the boat is submerged and the ventilators, not shown, of the boilerroom, and of course the hatches and ventilators leading into the main hull of the boat have been closed, the

doors

5, 8 and 14 are also closed and securely locked air-tight. \Vhen it is desired to pass from one end of the boat to the other, one first enters either air-lock 10, as the case may be, and closes and locks the door 8 leading into said airlock. The hinged portion 15 of the grating in said air-lock is then lifted so that passage may be had down through the vertical portion of said air-lock; the door 1 1 controlling the opening into the passage 12 from said air-lock 10 is then opened to permit entrance into the passage 12 after which the said door 14 is closed and locked. Then one has traversed the passage, the door 141 at the opposite end thereof is then opened to permit entrance into the lower end of the air-lock 10, after which the said door 14 is closed and locked. The person then climbs up the air-lock 10, and lifts the hinged section 15 of the grating 15 and then opens the door 8 leading into the main hull and passes out into the opposite end of the boat, thus avoiding the necessity of passing through the highly heated atmosphere of the boilerroom. It will be understood that in passing from one end of the boat to the other, the several doors leading into the air-locks and the passage 12 are immediately closed when entering the air-locks and the passage, so that but little of the heat from the boilerroom is permitted to escape into the main hull of the boat when one passes from one end of the boat to the other.

20 designates a horizontal partition arranged in the boiler-room and is supported by longitudinal girders 21 as shown in Figs. at and 5. While I have shown the boilerroom as substantially cylindrical in cross section, I do not wish to be confined to this particular form, as it is obvious the bottom of the boiler-room may be provided with a substantially flat floor and the partition or floor 20 thus dispensed with.

IVhile I have particularly described a construction best adapted for the purpose as set forth, it is obvious that various changes in the form, proportion and the minor details of construction may be resorted to without departing from the spirit of or sacrificing any of the principles of the invention.

\Vhat I claim is 1. A submarine or submersible boat, having a boiler-room arranged therein, air-locks formed at the ends of the boiler-room and communicating therewith and with the interior of the boat, a passageway arranged under the boiler-room and communicating with said air-locks, and doors controlling all of said communications.

2. A submarine boat, having a boiler-room arranged therein and spaced from the main hull of the boat, bulkheads forming closures for the ends of said boiler-room and connected thereto airand water-tight, said bulkheads being connected to the main hull, transverse bulkheads arranged within the main hull and connected thereto airand water-tight, said bulkheads being spaced from the bulkheads closing the ends of the boiler-room, doorways or openings formed in said bulkheads, doors for said doorways or openings, a passageway arranged in the space formed between the bottom of said boiler-room and the main hull and comn'iunicating with the spaces formed between the said bulk-heads, doors controlling said communications, and hinged gratings arranged in said latter spaces.

8. A submarine boat, having a compartment arranged therein providing a boiler room and spaced from the main hull of the boat, bulkheads forming closures for the ends of said compartment or boiler-room and connected airand water-tight to the main hull of the boat, longitudinal partitions arranged in the space formed by said compartment and the hull of the boat and in the lower end thereof, said longitudinal partitions being connected airand watertight to said compartment or boiler-room and to the main hull, and to said bulkheads, transverse partitions or bulkheads arranged within the main hull and spaced from said first mentioned bulkheads, doorways arranged in said bulkheads, and doors controlling said doorways, all substantially as and for the purpose specified.

4. A submarine or submersible boat, havi lg a compartment arranged within the main hull thereof providing a boiler-room and spaced from the main hull of the boat, bulkheads closing the ends of said compartment or boiler-room and having their edges connected air and water-tight to said main hull, transverse partitions or bulkheads spaced from said first mentioned bulkheads and having their edges connected airand watertight to said main hull, all of said bulkheads having doorways formed therein, doors controlling said doorways, frames arranged in the spaces formed by and between the adjacent bulkheads providing air-locks, a passageway arranged under said boiler-room and communicating with said air-locks, and doors controlling said communications.

In testimony whereof I have hereunto set my hand this 9th day of April, A. D. 1915.
