for increasing its buoyancy, which is sella` hailing so that its buoyancy will not he reduced by water entering the boat and which is provided with means for removing water 'from' any of the said air compartments in the case of injury thereto.v

In accomplishing the objects of the invention, l have provided the improved details of construction, the preferredformsv of which are illustrated in the accompanying drawings, wherein- Figure 1 is a central, longitudinal sec tional view of a boat constructed in accordance with the present invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a transverse sectional view of the boat.

Fig. 4 is an enlarged sectional view through one of the valved hailing pipes.

Fig. 5 is a sectional view ot a valve ot an alternative type, to be used in lieu of that shown in Fig. 4.

Referring more in detail to the several views of the drawings, wherein like reference numerals designate the same or like parts- 1 designates the hull of the boat taken as a whole. This may he of any suitable shape and size, but preferably of sheet metal con` individually sealed air tanks 5, arranged end' to end along the sides and at the ends of the 'boat upon thc bottom 2 and beneath seats 6r which are secured along the boat walls as shown in Fig. 3. rlChese tanks, or compart-V ments, are for the purpose of increasing` the buoyancy of the boat and for preventing its being capsized by high waves or rough water.

Extending longitudinally ot the boat,

vfrom end to end above the bottom 2, is a bulkhead 8 which is principally t'or effecting counterhalance of thehoat when full ot water, and which serve the purpose et preventing occupants of the boat from being thrown from side to side it the boat rocks, for preventing water splashing over one side of the boat from `lilling or falling into the entire boat and for adding strength andy rigidity tothe construction.

Ink order that the boat will be seli hailing, I have provided at opposite sides of thepartition wall, at spaced intervals along 'the boat, a plurality of drain pipes l0 which, at their upper ends open through the bottom 2 and at their lower ends open through the bottom of the hull so that water that may splash within the boat will drain therefrom by gravity. y

in order to prevent water from entering the boat through these pipes, there is provided in each pipe a wood or cork iioat valve l2. These valves areslidahly mounted on pins 13 extended downwardly from perforated cover plates 14, which are threaded into the upper ends of the pipes in such manner that incoming water will raise the floats against the cover plates to close the perforations and thus prevent its entering the boa-t, while water draining from the boat will move the float downward away from the coverand provide an open passage to the bottom of the hull.

In Fig. 5 l have illustrated an alternative valve construction wherein the drain pipes have a horizontally turned elbow portion 15 provided with a pivotally mounted gravity valve 16 to swing outwardly from and against a flange or seat 17 to control the passage of water as previously described.

For the purpose of hailing the comparte f in the boat upon the floor 2 where it will pass outwardly'through the drain pipes 10.

VThe boat is'further provided with transverse seats 22 beneath which watery caslrs, bread breakersor the like may be placed. Also with the usual oar locks, a rudder, and mast socket so that the boat may be properly navigated.

It is apparent that should aV boat sov constructed, for any reason, become lilled with Water, the buoyancy afforded by the airtight compartments will raise it sufliciently to cause the water therein to drain quickly through the pipes l0 so that the boat will ride at its normal level in the water.

It is also` apparent that the disposition of the air tanks will greatly increase the buoy ancy of the boat and will insure it agai-nst capsizing. Y

- Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent, is:

1. A boat of the class described having a false bottom spaced from the floor of the hull forming an Y air-chamber, transverse Walls dividing Said chamber into a plurality of individual air-tight compartments, and a .partition wall above said falsebot-tom dividing the boat longitudinally. f

2. A boat of the class described comprising a Jfalse bottom spaced from the Vbottom of the hull and forming an air-tight chamber of such volume that the boat will ride normally with said false floor above the outside Water level, partitions placed transversely acrossl said chamber dividing itV into a plurality of individual, air-tight compartments, a par-V of said hull, perforated closures for theV upper ends of said pipes, and float valves mounted beneath said closures permitting and outflow oie water but movable against said closures to prevent any inflow therethrough. Y

3. ln a boat of the class described havinof a false bottom spaced from the bottom of t e hull and forming an intermediate air chamber, a drain pipe extending through said false bottom and hull and opening at its opposite ends to the interior ofthe boat and exterior of the hull, a perforated cover plate mounted in the inner end of the pipe, a pin extending downwardly from said plate, a float slidahle on said pin from and against the plate to permit an outflow of water but preventing an inow therethrough.

Signed at Seattle, l/Vashington, this 16th day of December, 1920.
