BOAT.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application led March 19, 1918. Serial No. 223,370.

To all whom z't may concern:

Be it known that I, JOSEPH WYMORE, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Boats, of which the following is a specification.

My invention relates to boats and has for its object the production of a vessel which will continue to float after Contact with a mine or torpedo and which will provide means for maintaining passengers out of the water until they may be rescued.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be particularly pointed out in the claims following a detail description.

In the drawings:

Figure l is a side elevation of a vessel embodying my invention.

Fig. 2 is a plan view of the same partly broken away and in section.

Fig. 3 is an elevation of the stern.

Fig. l is a view partly in elevation and partly in longitudinal section.

Fig. 5 is an enlarged transverse section of the line 5-5 of Fig. l. t

In carrying out my invention, I provide a plurality of hulls, four being shown in the accompanying drawings and indicated respectively by the reference numerals l, 2, 3 and 4. These hulls will be spaced apart and the innermost hull l will carry the engine and other machinery, indicated at 5 in dotted lines in Fig. 5 as well as the propeller 6 and the rudder 7. Each hull will be constructed with a keel 8 and the keels of the inner hulls will each be disposed vertically above the respectively subjacent keel so that they will act as supporting members to maintain the several hulls'out of direct contact and, consequently, air chambers will be formed between the several hulls. The hulls may be also re-inforced by beams 9 extending vertically and longitudinally and these beams will further aid in maintaining the spaced relation of the several hulls and producing air chambers between them. The outer hulls 2, 3 and at will be constructed at their sterns with openings 10 defined by inwardly extending plates l1 of such size and shape that they will extend around the propeller and rudder and the supports for the same and, consequently, will permit the several hulls to clear the propeller and rudder lwhen becoming detached from the vessel.

- ranged iiush with each other so as to provide a support for the main deck l2 of the vessel. A lower deck 13 may be suspended from the main deck in any desired manner and a cabin 14: may be built uponV the main deck as will be readily understood. The main deck will be provided with a mast l5 carrying sails and the smoke stack 16 may be extended from the inner hull through the lower deck 13 and the cabin and be detachably connected with the boiler furnace.

It is thought the advantages of my improved construction of vessel will be evident from the foregoing description taken in vconnection with the accompanying drawings. T he spaced relation of the several hulls providing air chambers or cells between them imparts great buoyancy to the vessel so that under ordinary conditions it will float steadily and may be propelled with a minimum consumption of fuel. The provision of a plurality of hulls in spaced relation tends to counteract the disastrous effect of a mine or torpedo inasmuch as the penetrating power of the mine or torpedo is very materially lessened, so that when the outer hull is struck it will at once release itself from the inner hulls and sink when the vessel may be navigated upon the remaining hulls. Should all the hulls be destroyed, the deck 13 with the cabin thereon will form a very ellicient raft upon which the passengers or crew may float until land is reached or some other vessel meets the raft and rescues the persons thereon. The construction is very simple and a vessel embodying my invention may be produced at a low cost which will be determined by the size of the vessel.

Having thus described my invention, what I claim as new is:

1. A ship provided with a plurality of similar hulls arranged one within another in spaced relation and successively removable upon being flooded, propelling and steering devices carried by the innermost hull, the outermost and intermediate hulls being provided at their sterns with inwardly extending plates defining openings to clear the propelling and steering devices, an upper deck supported on the hulls and releasable therefrom as the hulls are Hooded, and a lower deck suspended from the upper deck and normally housed within the innermost hull.

2. A ship including a plurality of spaced hulls fitting one within the other and terminating flush at their upper edges7 a main deck overhanging the upper edges of the hulls to close the spaces therebetween and detachable from the hulls, a lower deck suspended from the main deck within the innermost hull and free with respect thereto whereby the hulls may successively separate from each other beginning with the outermost hull and the innermost hull separate from the main and lower dec-ks, the connected main and lower decks being adapted to provide a raft, propeller mechanism projecting from the innermost hull through the outer hulls, and plates carried by the intermediate and outermost hulls and defining openings about said propeller mechanism adapted to clear said mechanism whereby the intermediate and outermost hulls may sink away from the innermost hull.

3. A ship including a plurality of spaced hulls fitting one within the other, propeller and steering` mechanism projecting from the innermost hull through the intermediate and outermost hulls, and plates mounted upon the intermediate and outermost hulls at the Sterns thereof and defining openings about the propeller and steering mechanism adapted to clear said mechanism whereby the intermediate and outermost hulls may sink away from the innermost hull, the said plates successively fitting snugly one over the other and being provided with inwardly directed side flanges abutting the innermost hull.

In testimony whereof atliX my signature.
