"Be it knownfthat I, Ciaanmas ALF ED JAMES, a. subject of the King of GreatiBritfain, residingat 148 Upper Claptonroa'd,
(E. 5,) London, England, have'inventednew and useful Improvements in Vessels Navigable in Water, Air, or "Both, ofwliich'the following is aspecification.
My inv ention' relatesv to an "improved boat or vessel which is navigable in the water or partly in the waterand partly in the air and which undercerta in circumstances may be caused to rise off the water and float wholly in the air, the object of my invention being to provide a vessel capable of attaining a greater speed than can be obtained with ves-r sels as heretofore constructed.
The hull of my improved boat somewhat resembles that of a flat bottomed boat heretofore proposed having a continuously and practically uniformly increasing draft from the water level toward the bow to a maximum at the stern.
According to my invention, however, the fiat bottom of the boat is extended upward above the water line for a large proportion of the length of the vessel, the bow or stem of the vessel is considerably above the water level, whereby as the boat is propelled reaction takes place between the immersed portion of-the bottom and the water and between the unimmersed portion of the bottom and the air, the united reactions tending to lift the boat and thereby reduce the immersion and consequent water friction. Furthermore the sides of the hull gradually diverge from the stern toward the bow which is the widest part of the vessel. 1
As the-speed of the boat increases the reaction of the air and water againstthe inclined bottom will tend to increase the inclination of the latter to the horizontal, and diminish thev area of immersion whereby with a sufiiciently light boat and the necessary power the boat can be practically lifted out of the water and even in some cases en- Specification ofLetters Patent. Patented Feb.24,II920. 'Apjplication filed September 10. 1919, Serial n); 322,973;
rig- .*sap1aa, nd 1 l a section onfthe line 4 4-, Fig. ,1.
Figs. 5 and'ti are respectively aside view and a plan illustrating "the a lic tio f planes to'the boat. I 1 H Figs/7 and8 are respectively aplan and a stern viewfshowmgthe'connection of two boats,. and iv V Fig 9. is a section on the line'9;9., Fig-f7- In these figures a indicates the inclined bottom and 7 b the sides of the boat,the said bottom having, as "shownfthe shape in'pl'an view of an isosceles'triangle, while the sides, which converge toward .the stern, where a rudder is fixed, are of approximately trifor the accommodation of a crew, and for ballast tanks, such as h, it.
Although under normal circumstances and at a given speed a boat thus constructed would never wholly leave the water it would be possible, either by increasing the speed to the requisiteextent or by lightening the boat, for instance, by discharging ballast, for the boat to lift wholly OK the water and pass over a break-Water or other obstruction, and to facilitate such an operation the boat may be provided with planes, say, as indicated at 2' Figs. 5 and 6 such planes, when not required, being taken down and stored in the boat. The boat may also be provided with masts and rigging.
'Itis to be understood that by the term inclined plane I do not limit myself to a plane which is rectilinear either longitudinally or transversely as thesaid plane may have either a concave or convex curvature in either or both of these directions.
If desired two or more boats constructed as hereinbefore described may be connected together, as indicated, for example, in Figs. 7 to 9 wherein Z0, is indicate the two boats united at the bow as at l and connected together amidship and astern' by ties or braces m, n. 7 Also the floats of'hydro-planes can be constructed in the manner hereinbefore described.
Claims: i v 1. A boat including a hull having a triangular shaped bottom, the bow end of which is formed by the base of the triangle and the stern end of which is formed by the apex of said triangle, the bottom being I gradually inclined downwardly from bow to stern, and said hull being balanced to cause substantially the front half of the hull to project above the surface of the water on a which the boat floats. v
2. A boat of the kind defined by claim 1 having an aerial propeller arranged at its bow for causing the boat totravel'.
3. A boat of the kind defined by claim 1 having a water propeller at its'sternnormally occupying the water, and an i l Propeller at its bow, I
,4. A hydroplane comprising 1 11111 having a bottom which in plan is in the shape of an isosceles triangle; thebow end-01"- the bottom being formed by the base of the triangle and the stern end being formed bythe apex of said triangle, triangular shaped sides cooperating with the bottom to form the hull, and the bases of the triangular sidesv meeting at the stern of the boat,,said bottom water,'and an aerial propeller arranged at the bow;
5, A plurality of hulls of the kind defined in claim 1 having certain ends of the bows connected together and braces connecting the sterns and spacing the sterns apart.
