SUBMARINE BO Application filed August 16, 1915.

To all whom it may concern:

Be it known that l, SinoN LAKE, a citizen of the United States. residing at Milford State of Connecticut have invented certain new and useful Improvements in Submarine Boats, of which the following is a specifi-- cation.

The, invention relates particularly to an improved submarine or submersible boat designed for commercial purposes and par ticularly for carrying cargoes of various description.

The invention consists in the peculiar and of a non-pressure-resisting outer hull; of the arrangement of a, pressure-resisting inner hull in Which is arranged an engine compartment, working compartment and living quarters; in the peculiar and novel arrangement of tanks Within the outer hull which are designed for carrying the cargo; and in the: novel manner of bracing said tanks in position and tothe outer hull the whole being so arranged as to provide a thoroughly rigid construction of relatively light Weight material.

The invention further novel-features of construction and peculiar combinations and arrangements of parts as will hereinafter befullydescribed and then claimed. i

.whereby observations may be made when divided by a horizontal partition 18 (Fig.

2), and connected airand water-tight to the lower side of this partition is a substantially U-shape trough 19 having closed ends 20. The upper longitudinal edges of the sides of the trough 19 and its ends 20 are connected airand water-tight to the horizontal partition 18, whereby to provide a battery compartment 19' in which is arranged the battery cells 21 from which the necessary power is derived foroperating the boat submerged and when in submerging condition. Access to the battery compartment 19' is had through a hatchway con trolled by a cover 19, as shown in Fig. 1.

As shown, the batterv compartment does not extend throughout the length of the space formed between the transverse partitions 4t and 5, so that a well 22 is provided at each end of the battery compartment. Mounted in each well is a hydraulic cylinder 23, in each of which operates a piston 7 (not shown), the rod 24 of each having its lower end connected. to one end of an arm or lever 25, pivoted intermediate its ends to the sides-0f a recess formed in the keel l of the outer hull 1, and the free end of each is provided with journals in which are mounted 'a bearing roller or traction wheel .26, the Wheels being designed to contact with the water-bed when the boat is operating upon or immediately adjacent to the water-bed. As the construction and the operation of these traction wheels forms the subject matter of Letters Patent No. 726,705, granted to me April 28, 1903, it is not thought necessary to describe the same in detail, a-ndattention is therefore invited to the said patent. for further understanding of their purpose.

The spaces formed between the outer nonpressure-resisting hull; the transverse part'itions 4 and 5, and the inner pressure-resisting hull 7, also the spaces in the forward end of the boat formed by the transverse partitions 5 and 6, and also the space in the aft r end of the boat, aft of the transverse parjtition 4, are divided by horizontal partitions 18' having openings formed therein controlled by valves 182 (Fig. 2), the stems of the valves being extended into the inner pressure-resisting hull 7, whereby the valves may be operated from Within the several compartments of the said hull section 7, as will be hereinafter described.

The spaces upon the opposite sides of the inner pressure-resisting hull], between the partitions 18 and 18, are divided by horizontal partitions 18 having their inner and outer longitudinal edges connected, respectively, with the plating of the inner hull 7 and the plating of the outer hull 1, and their forward and after edges connected, respectively, with the transverse partitions 4: and 5, said horizontal partitions l8 having a plurality of openings (not shown) whereby the spaces above and below the latter'partitions are in open communication. The spaces in the forward end of the boat, formed by the partitions 5 and 6, are divided 'by horizontal partitions 181, the spaces thus formed being also in open communication through openings183, shown in Fi 3.

The partitions 18, 18, 181,- and 18" are formed with circular openings 27 (Fig. 1) Y through which extend vertically arranged cargo-carrying tanks 28. The lower ends of the tanks are mounted upon transverse horizontal plates 29, arranged preferably in step-like order so as to meet theconditions imposed by the longitudinal and transverse curvature of the outer hull 1. Suitable longitudinal girders 30 are provided to strengthen the horizontal plates 29 and the bottom of the U-shape trough 19, and, in

practice, it will be understood that the girders and the plates will be securely connected together and to the plating of the ribs of the outer hull 1 as in all ship constructions.

In practice, the tanks are provided at their lower ends with flanged rings or frames 26 (Fig. 1), which are securely riveted to their supporting plates 29, and are also connected-to their respective horizontal partitionsby means of circular rings or frames 31, shown most clearly in Fig. 4, said rings or frames being L-shape in cross section, and riveted to the tanks and to the said horizontal partitions. The tanks 28 are providedin their tops with openings controlled by suitable covers 32, and the deck 1 of the outer hull is formed with alining hatchways controlled by suitable covers 33, so that access to the tanks may be readily had from the deck of the boat when loading or removing the contents into and from the said tanks.

In practice, the upper partitions 18 will be connected airand water-tight at their longitudinal edges to the sides of the outer operating upon the surface.

hull 1, so as to provide water-tight comartments in the upper portion of the outer hull to thus add buoyancy to the boat when When the boat .issubmerged, the valves 182 (Fig. 2) will be opened so as to permit water to flow into the spaces above the' partitions 18, as well as into the superstructure, valves heretofore referred to, so as to prevent the collapse of the deck of the boat, it being understood, of course, that when the .boat is submerged, the sea-valves (not shown) controlling the admission of waterballast to the lower compartments of the boat will be opened so that the water may flow into and through the several compartments of the outer hull and into the spaces formed above the horizontal partitions 18. To empty the various water-ballast compartments, I purpose connecting them with pipes (not shown) extending from suitable compressed air-storage bottles 37, preterthe lower hold of the boat, thatis to say, in the spaces formed below the plates 29 at each side of the battery sothat when air is admitted to the spaces, the water will be blown therefrom, it'being understood, that as the water is ejected, the spaces will be replaced by air of such pressure as to equalize the external pressure, decks and partitions, and the sides of the It will be further understood,-that when empty of water, the spaces above the decks 18, as well as the space formed by the superstructure, will greatly add to the surface buoyancy of the boat, and'furthermore, that the said spaces may be utilized as living quarters for the crew when the boat is operating on the surface.

In the construction shown and described, the spaces formed. between the outer nonhull 1, and the inner prespressure-resisting sure-resisting hull 7, and the spaces formed I at the forward and after ends of the boat are designed to be filled with water from the of water when the boat is surrounding body of course, be

the several compartments of the inner pressure-resisting hull 7, will be provlded for controlling the admission o-f'water to the aforesaid spaces.

Suitable pumps (not shown) Wlll also-be provided for pumping the water from the said spaces to emerge I the boat:

-' The tanks 28 ciently heavy weight material to withstand the pressure of submergence'equal to that for which the inner pressure-resisting hull 7 is designed, and when empty, or when carrying such materials in which air spaces through the.

'eral cargo-carrying and thus prevent the are constructed of satin are left in the tanks, that is to say, materials other than liquid, or when the tanks are not completely filled with liquid, I purpose admitting air under pressure to the tanks so as to prevent any possibility of collapse, the air being led into the tanks through pipes 36 (Figs. 1 and 2), extending from a suitable source of supply (not shown), the supply source being furnished with air either by a suitable air pump (not shown), similar to those installed upon all submarine boats, or from the compressed air bottles 37 carried in the lower part (or hold) of the outer hull upon either side of the battery compartment 19, as hereinbefore described.

It will be understood that in the construction shown, the entire space between the outer and inner hull sections forms the bal by water, so that I am able to build a strong and durable outer hull, as well as the superstructure, of comparatively light weight material and, of suflicient strength to avoid danger of collapse when operating upon the surface in rough weather. It will be further understood that I may provide the sevtanks with sea-inlet valves, whereby water-ballast may be admitted into any of the tanks in order to trim the boat when full loads are not carried within the tanks.

By my construction, I provide a. boat with a larger amount of reserve buoyancy, and

consequent greater surface buoyancy than has heretofore been produced. It will be further understood that the tanks may be connected together and to the outer hull, andto their adjacent partitions by suitable braces, but as these latter features constitute details of construction well known by those skilledin naval architecture, it is not thought necessary to show or to describe them.

It will thus be seen that I provide an eX ceedingly novel construction of submarine or submersible boats particularly designed for carrying cargoes of various descriptions, and which will be found of inestimable advantage in supplying blockaded .countries with food-stufi': or war materials during hostilities, and which may be readily submerged, when upon the high seas, in the event of interception by an enemys fieet.

"When operating in danger zones, such for instance, asm the presence of hostile ships, and when entering a blo-ckaded port, the

crew of the submarlnewillenterthe inner pressure-resisting hull section and from the said section navigate the boat past the hostile shipsfit,- of course, being understood that the boat will, from time to time, be

their bearings as in the operation of all sub.

marine boats.

\Vbile I have briefly described the elements best adapted to theconstruction set forth, it is obvious that various minor changes in details of the boat, and in the construction shown, may be resorted to Without departing from the spirit of, or sacrificing any of the principles of the invention. Also, that my improved freight carrying boat may be provided with fenders such as is shown and described in Letters Patent No. 1,135,537, granted to me April 13, 1915, assigned to the 'Lake Torpedo Boat Com pany of Maine, to thus enable the boat to be maneuvered through a mined field or under nets extended across a channel. without fear of detection, When entering a port.
