This invention relates to improvements in marine vessels, and one object of the invention is to provide a vessel embodying a submerged multi-float cargo-carrying floatation base, a superstructure lying wholly above the surfaceof the water at such an elevation as to normally allow the Waves to pass beneath it, and a skeleton type of connecting trussframing rigidly oining and bracing the subbase and the super-structure, the elements of the base and the framing' being of streamline formation so as to reduce to the minimum displacement changes and resistance to the propulsion of the vessel.

A further object of the invention is to provide a vessel of this character in which the floats of the submerged floatation base are of such load carrying capacity and the stream-line framing so constructed that a vessel of substantially uniform displacement will be produced, namely, one in which the amount of displacement will not be materially increased by variations of load weight up to full cargo weight, so that the amount of the cargo carriedwill not to any appreciable the displacement or affect the extent change speed of the vessel or amount of power required to drive it at a given speed.

A still further object of the invention is to provide a novel and improved construction of vessel of. this type which will have great strength, stability, maneuvering qualities, carrying capacity for freight or passengers, or both, greatspeed and cruising range and capability of operating safely in stormy weather and in either deep or shallow water; which will belittle-rocked or otherwise disturbed in stormy weather; which will be which may be of great size-and yet propelled with relatively less power than vessels of standard types; greater comfort for passengers than vessels of standard types A still further object of the invention is to provide a vessel which embodies means for carrying airplanes and upon which airplanes may readily alight and from which they may be readily launched.

The principle of this invention-allows vessels of very large size to be economically conskeleton structed and operated and hence may be advantageously employed in of passenger and freight carrying vessels of great carrying capacity, floating hotels, theaters and the like, airplane carriers or mother ships, troop transports, naval or merchant repair ships, hospital ships, salvage ships, light ships, sea floats for airplanes and airships, and other similar-purposes.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which igure 1 is a View in side elevation of an embodiment of marine vessel constructed in accordance with my invention.

Figure 2 is an end elevation of the same.

Figure 3 is a vertical longitudinal section through one of the floats or submarines and the connecting pillars of the framing.

Figure 4 is avertical transverse section on line 44.ofFigure 3.

' Figure 5 is a horizontal transverse section on line 55 of Figure 3.

igure 6 is a sectional perspective view through a portion-of the truss-framin In the illustrated embodiment of the invention, the vessel comprises a floatation base consisting of a plurality of floats 1, a superstructure 2, and a truss-framing generally indicated at 3, which supports the superstructure from the floatation base and rigidly connects the floats of the base with each other and with the super-structure.

Any suitable number ofthe floats 1 may be employed ateaoh side of the longitudinal center of the vehicle. In the present in-' stance two floats are shown at each side of thelongitudinal center of the vessel, equidistantly disposed, respectively, between the waist or transverse center of the vessel and the bow and stern portions thereof. practice, each float 1 may be of a length'of from one-fourth to one-fifth more or less of the lengthof the vessel, so that, with a yes-- sel of, say, an overall length of one thousand feet, each float will be of a length of from'two hundred to two hundred and fifty feet.

the construction The floats are so proportioned in ma 'length, breadth and depth, and of such sides or surfaces of will 0 rate weight and load carrying capacity with respect to the weights and dimensions of the super-structure and connecting framing that major portions of the floats will be immersed when the vessel is unloaded, only the top portions of the floats projecting above the surface of the water, while when the vessel is loaded .to a certain degree the floats will be entirely immersed in the water. In Figure 1 w-w represents the water line when the vessel is unloaded, and indicates its minimum displacement, while y-y represents the water line when the vessel is loaded to a maximum degree, from which it will be seen that in the fully loaded condition of the vessel the floats l and more or less of the framing 3 will be immersed in the water, while the super-structure 2 will be supported by the framing at such a level with respect to the floats as to lie wholly above the surface of the water. The height of the framing is preferably such in practice that when the vessel is fully loaded and the floats submerged to a maximum degree the bottom of the super-structure will lie at a level above the crest of even very high under all normal conditions the waves'will pass below the body of the super-structure. The floats 1 are built of metal plate riveted or welded together in the usual way, and are trussed in any suitable manner to adapt them to resist all pressures and strains to which they are sub'ected in service. Each float may consist o abody or main section' l of approximately cylindrical, oblong rectangular or other suitable form in cross-section, and an outer shell 5 surrounding the sides, bow and stern portions of the body 4 and imparting to the float a desired streamline for1 mation. As shown in the'present instance, the float is of ovoidal form, longitudinally, transversely and in horizontal longitudinal section, givinglit a form which provides a proper breadt for stability and floatation efiect, while at the same time rendering it capable of traveling with minimum reslstance through the water. The shape of each float is also such that as all of its walls or surfaces slope in one direction or the other a geometrical bracing formation is obtained, while all the float slope in one direction or the other to allow water flow with a minimum of skin friction. This shape of the float is also of great value for the protection of ships against torpedo attacks in war-time, as the sloping surfacesof the floats as deflectors, either causing the torpe o to be entirely warded OE and diverted from its course without injury to the ship, or preventing a fair strike so that in the event of the explosion of the torpedo the amount of damage done will be greatly reduced.

It will be observed that the body 4: as shown waves, so that in the present instance is provided with flat arallel sides 4" and cross partitions 4* forming end walls and that the sides 4" continue beyond the end walls and form the sloping bow and stern portions 4 and 4 and that the outer shell 5 consists of longitudinally curved fairings or shell sections of ovoid cross section which enclose the sides 4 between their top and bottom edges and merge at their ends into the bow and stern portions 4 and 4", whereby a sectional float and having the conformation described may be built by a ready and economical shaping of sheet metal of required thickness, the plates of which may be either welded or riveted together. The body and shell sections 5 may be mutually braced by cross braces 5 acting also as partitions to form storage or other compartments. As shown in the present instance, the floats are each provided with propelling means, such as a screw propeller 6 driven by a suitable motor 7 within the float, and in practice each float may be provided, if desired, with its own steering gear and all necessary equipment rendering it a navigable unit. Each float therefore constitutes a body of submersible type, so that in the event of derangement of or damage to the propellers or steering gear of any one or two of the floats the vessel ma still be propelled and steered by means of t e propelling mechanism and steering ear of the other floats. It is to be understood, however, that the propellers upon thefloats may be driven by electric motors which may be supplied with current furnished from a common generator on the super-structure. Also it is to be understood that in the use of steering rudders or the like on .the floats, these may be controlled in unison by a master steering gear on the super-structure, or that in lieu thereof other steering gear of great strength I mounted on the super-structure or the trussframing may be employed.

Each float 1 is designed as a cargo-carrying craft and may be divided by suitable water-tight partitions into watertight compartments and living and cargo-carrying quarters or chambers, access from one to the other being afforded through suitable doorways or manholes which may be closed by doors or manhole plates 8. Each float is provided in its'top with one or more openings or hatchways 9 for the introduction of fuel and supplies and the introduction and withdrawal of cargo, which openings or hatchways are) I cl normally by water-tight covers 10.

The framing 3 com rises pillars-11 arranged inpairs, a pair oi such pillars connecting each float 1 with the su r-structure 2 and forming a sup ort for the utter. The pillars 11 of each pair are connected and stayed at their lower ends to the bow and stern portions of the float to which they are attached and then project upwardly in converging relation and are connected and stayed to the bottom of the super-structure 2. Each pair of pillars is thus so arranged as to form with the portion of the bottom of the super-structure to which they are attached an arched supporting column for the super-structure and a triangular form of suspension for the float, whereby a connecting andreinforcing structure between each float and that )ortion of the super-structure carried theret) duced. The pillars ll of each pair are aring crossed and the connecting ranged one in rear of each other, so that all the pillars of the floats at each side of the vessel are in longitudinal alinement, and the pillars are of ovoidal form in cross-section, as shown in Figure. 6, or of other suitable equivalent shape so as to secure maximum strength of construction with a streamline shape. The pillars provide passages or companionwavs between the bow and stern portions of the oat and the overlying portion of the super-structure, in which ladders or stairs 12 of suitable type may be arranged to permit passage of the officers and crew between the floats and the super-structure, aswell as to permit fuel, provisions or freight to be introduced from above through the companionways into the floats after the covers 10 are applied, as well as the discharge of cargo in part through these hatchways whenever desired or required. Through the pillars ventilation tubes or pipes may extend from the super-structure to supply fresh air to the interior of the floats and to discharge vitiated air, gases of combustion from the motors and any other noxious gases that may be present. Through the pillars also fuel may be conducted to the floats from auxiliary storage tanks or reservoirs in the super-structure, when motors of internal combustion or other fuel-consuming type are used in the floats for propelling purposes.

The truss-framing also includes arched cross girders 13 connecting the front floats with each other and the rear floats with each other, and longitudinal truss girders 1i connecting the floats and inner pillars of the columns with each other at each side of the vessel. Each girder 14, as shown, consists of diagonally arranged girder members 15 each forming a topbrace for the inner pillar of one float and a bottom brace for the inner pillar of the other float, said members 15 bejoined at the Waist line, as

at 16. A central arched cross girder 17 con- .nects the two longitudinal girders 14 at the points 16, thus completing the structure of framing. All the elements of this framing are of the hollow type and streamline form shown in Figure 6, and a skeleton type of truss-framing is thus produced which is at all points of streamline contour so as to adapt it to easily cleave the water and move with a minimum of resistance therethrough. This type of framing y is pro-- or of triangular form,

may be comparatively light in weight but of such strength as to support a very long and weighty super-structure and to tie the floatation base and super-structure so firmly and rigidly together as to produce a vessel which is of such strength as to be practically indestructible and unsinkable.

The super-structure 2 may be built to serve any desired purpose. with any suitable number of decks with a pilot house and saloons and cabins or quarters for oflicers, the crew and passengers and compartments for provisions, extra fuel and auxiliary freight. The whole of the superstructure may be dev ted to these purposes, if desired, and freight carried in thefloats, so that a passenger great capacity will be provided. As this super-structure maybe of great size it adapts the vessel to be built to serve as a floating hospital or theater or troop transport. airplane carrier or mother ship, as a naval or Y merchant repair or salvage ship, or as a light ship or sea float for airplanes and airshlps, and for many other similar purposes.

When used as a light shipor sea float for air- It maybe provided planes it may be anchored if the water is sufficiently shallow or may'cruise slowly within given limits. Because of its type and strength of construction this vessel is adapted to navigate both deep and shallow waters and is of such stability as to easily ride the waves in the roughest weather without damage or material rocking, rolling or other motion. Be-

cause of its great stability, no ballast need be carried on this ship, giving greater room for freight or fuel storage, and passengers. crew and livestock may be transported with greater comfort and convenience.

The super-structure is provided with a top deck 18 of the same length and breadth, i. e., of the same superficial dimensions as the body of the super-structure. This deck may serve as a carrier deck for aircraft. It also serves as an airplane alighting and launching platform, permitting airplanes for mail and express transport purposes or observation purposes to-travel to and from the ship. The great area of this deck or platform allowed by the permissible size of the super-structure will give ample running space for take-off and landingoperations without special equipment, but..if,desired, nets or the like to arrest the motion of an airplane in alighting and catapults for launching purposes may be employed.'- As stated, the vessel, provided with such a deck, may be used as an anchored or cruising sea float for airplanes on which airplanes engaged in overseas flights may alight for reprovisioning, refueling. repairs or other purposes, for which this vessel is admirably adapted.

In addition to the features above noted, a novel and special advantage arises from the construction of a vessel embodying my invcntion. As stated, the floats 1 constitute cargo carriers. When the floats are unloaded, i. e., without cargo load, these floats are not entirely submerged, their upper surfaces projecting just above 00-00. When the floats are loaded the floats descend and the water level rises to a point below'the line y'3 and line 00-11:, at which the floats are entirely submerged. I The weight of the cargo carried by these floats gives great stability, and when the floats are loaded a condition approaching maximum displacement is reached, beyond which any added displacement is more or less negligible so far as resistance to propulsion and reduction of speed is concerned because of the use of the skeleton streamline framing 3. It will, of course, be understood that after the floats are loaded and the condition above established is obtained, the addition of a superload weight (weight of passengers, etc.) upon the super-structure 2 will result in a further depression of the vessel and submergence of more or less of the framing 3, dependent upon he amount of superadded weight, until the displacement reaches a maximum and the water level also reaches a maximum at the line y-y. This maximum condition is reached when the floatation base and the super-structure are both loaded to full capacity,- he water level under general load conditions and varying between the tour it acts with a level y-y and a level at which the floats 1 are just immersed and their tops lie immediately below the surface of the water. The addition of any load weight, therefore, from such a general load condition causes increased displacement but only to such a degree as that resulting from a partial (more or less) immersion of the framing 3. By making this framing of skeleton form and streamline condisplacement minimizing eflect, such increase of displacement as may occur being practically unimportant from the standpoint of reduction of speed or increase of resistance requiring increased ower to secure a given speed. This vessel, t erefore has a maximum displacement below its full load carrying capacity from which it does not vary materia ly up to full load, the advantages of which will be readily to those versed in the art.
