UNSINKABLE BOAT.

Specification of Letters Patent.

Patented Nov. 28, 1911.

7 Application filed September 8, 1911. Serial No. 648,284.

To all whom it may concern:

Be it known that I, Josnrrr PASTOREL, a citizen of the Republic of France, and a resident of Asbury Park, in the county of Monmouth and State of New Jersey, have invented a new and Improved Unsinkable Boat, of which the following is a full, cle r, and exact description.-

My invention relates to unsinkable boats, and its object is to produce a vessel of this type which will be lighter, faster and better able to resist damage than other vessels of the'same description.

To this end I construct the'frame of my unsinkable boat of hard rubber, and cover it with sheets of rubber or rubber cloth in such a way as to form a number of independent air-tight compartments which can be inflated to increase the buoyancy of the boat. The elasticity of the materials" employed enables the structure to incur severe blows and shocks, because, when subjected to rough usage, theboat will yield instead of breaking, as it undoubtedly would in case common material, such as wood or iron, were employed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of reference indicate the same parts in all the views.

Figure 1 is a side view of the framework of my improved unsinkable boat; Fig. 2 is a top plan thereof, showing the same with the coverings in position; Fig. 3 is a sectional view on the line 3--3 of Fig. 2 Fig. 4 is a side view of the framework of. another form; Fig. 5 is a top plan of the parts shown in Fig. 4, the dotted lines showing the position assumed by the walls of the air-tight compartments when the same are inflated; and Fig. 6 is a'transverse sectional view on the line .66 of Fig. 5.

On the drawings, referring to Figs. 1, 2 and 3, the numeral 1 indicates the keel of the framework or hull, and this keel has-an upturned forward end 2, forming the cutwater of the bow of the boat, and having a rear portion 3. The upper end of the fore part 2 of the keel 1 and the rear part 3 are united by the gunwales 4, and the gunwales- 4 are supported above the keel and on each s de of the same by means of a plurality of IlbS 5. The entire framework of the hull of the boat may be molded in one piece for small craft, or made in sections for larger craft and united-together by rivets, bolts or cement, according to the choice of the builder.

i The deck of the boatisUindicwted-at-t, and it is shown as having an opening or cockpit 8 surrounded by a coaining 7. The rudder is shown at 9 at the stern, and it is controlled by means of a tiller 10. A motor 11 having a prop ller shaft 12, is used to supply the power lo run the boat, but it is obvious sired. v v

The framework of the hull is covered inside with sections of rubber cloth 13, which are secured to the keel, the gunwale and the ribs. These sections are made waterproof and air-tight; and the adjacent edges of the sections are cemented together to avoid the possibility of leakage. The, outside of the boat, on the other hand, from the lower edge of the gunwales down to the keel 1, is covered with sheets of rubber or other that I may use sails or oars if desheets 14 must be both waterproof and airtight and capable of stretching to a certain extent when the boat is in use. These sheets 13 and 14 form a number of longitudinal a ir compartments between the ribs- 5; and when these air compartments are filled with air, the rubber sheets 14 are forced outward,

as shown in Fig. 2, thus greatly increasing the buoyancy of the boat.

Along the gunwales 4 are arranged compartmental tubes 15, also made of sheet rubber or some other material having the same properties; and 16 are valves which are employed to admit air to inflate the compartments formed by the sheets 13 and 14, and the compartments of the tubes 15 aswell.

The'seats are shown at 17, arranged along the sides of the cockpin 8; and 18 1s a floor. The seats 17 may also be in the form of pneumatic cushions inflated by air the same as the air chambers at the sides of the hull.

Figs. 4, 5 and 6 illustrate a boat having a hull made of a somewhat difi'erent shape.

In this form a keel 19 is connected by means of ribs 21 to longitudinal braces 22 on each side, into which the keel merges at its oppo si'te ends. These longitudinal braces 22 are connected by an upper series of longitudinal ribs to the gunwales 4. The inside of the framework or hull is covered by means of sheets of rubber cloth 23, the same as the f of longitudinalair chambers, one series bewaterproof canvas or other strong Watering arranged above the other on each side of the boat, as plainly a pears from -Figs..4 and 6. The sections 0 sheet rubber.24 and the sections of rubber cloth 23 and 24 are, of .course, 0 mented together along adjacent edges to 'm ke the air compartments perfectly air-tight; and whenever it is desired to increase the buoyancy of the boat the air is pumped into the upper series of compart- .ments on each side of the boat through valves 25. This will stretch the sections of sheet rubber shown. at 24, forcing them out into the dotted-line position shown in Figs.

5 and 6, and thus greatly increasing the amount of water displaced and the buoyancy of the boat.

It will be obvious that I may also employ proof fabric as an additional protecting cover for the inside and outside of both forms of boat shown. This protecting cover will overlie the sections 13 and 14 forming the air compartments for the hull of the boat shown In Figs. 1, 2 and 3, as Well as the compartmental tube 15; and will overlie also the sectional sheets 23, 24 and 24' in the form shown in Figs. 4, 5 and 6. Such a covering would make the boat last longer, and would in'no way interfere with or diminish the increase in the buoyancy of the craft when the air compartments are inflated, which-is one of the chief objects of my invention.

From the above description it will be apparent that a boat made in the manner set forth can have a very great carrying capacityin proportion to its weight, and can be propelled at greater speeds than ordinary J boats. At the same time, the boat itself I will be strong and able to resist shocks and damage in caseof collision with other boats or impediments in the channel, because of the yielding. and resilient nature of the material employed in making it. Should the boat, for example, run against a snag, the sheets 14, 15, 24 or 24 would merely yield inward to some extent, stopping the boat and causing it to rebound without damage;

punctured or damaged, the remaining ones will be sufficient to enable the boat to remain shore.

I may em loy a number of iron weights to ballast the hoat and keep the same on an even keel. Both forms of boat shown are provided with two longitudinal rows of airtight compartments one above the other on each side'of the boat; and the upper rows of compartments when pumped full of air serve not only to increase the buoyancy, but on account of their'location they also serve to assistin the important function of trimming or ballasting the craft.

I" wish to have it understood that I may make certain small changes in the details of the above described construction, such as fairly fall within the scope and spirit of my terial secured thereto on the inside and outside thereof, said sheets forming air compart ments which increase the buoyancy of the said boat;
