ALUMINUM BOAT.

Application filed October 14, 1926. Serial No. 141,601.

' -An object of the invention is to provide.

in a boat structure of the character stated ribs of- SPGCltLl design and adapted particularly to be used in such a structure, seat bracesof aispecial .designand adaptation,

corner braces, a bow piece,.and, an arrangement of gunwales all particularly designed to be used in a boat of the character stated.

Afurther object of the invention is to provide a general arrangement of the parts specified whereby the structure of the boat as an entirety is rigidly braced and consequently is susceptible of withstanding the heavy strains to which it is subjected when being propelled through water. Also the boat structure is light in weight and may be read ily transported. over land or withdrawn or launched in the water. I

In the accompanying drawing:

Figure 1 is a top plan view of the aluminum boat.

Figure 2 is a transverse sectional view thereof cut on the line 22 of Figure 1.

Figure 3.,is a perspective view of one of the seatv braces of the boat structure.

As illustrated in the accompanying drawing the boat structure includes a hull 1, preferably of aluminum, but which may be of any other suitable material as for instance, wood, metal or fiber board. Transversely disposed ribs 2 of aluminumare located interiorly of the hull 1 and are spaced from each other in parallel relation as shown in Figure 1 of the drawing. These ribs are connected at their ends with inner gunwale strips 3. Other gunwale strips 4 are located interiorly of the hull 1 and are connected with the ribs 2 along lines spaced below the upper edge of the hull 1 and seat boards 5 rest at their ends upon the gunwale strips 4 and consequently are located below the upper edges of the hull 1. Braces 6, of light metal as for instance, aluminum, are provided at their ends with transversely dis posed heads 7 and the heads are provided with perforations 8 which are located beyond the side edges of the intermediate portions of the braces 6 as best shown in Figure 3 of the drawing. The heads 7 are disposed in planes at an angle to each other and the upper heads 7 are secured to the gunwale strips 3 and the lower heads 7 are secured to the seat boards 5 by means of bolts, screws or other securing devices whereby the intermediate portion of the braces 6 are disposed at angles with relation to the plane in which the seat boards 5 lie as best shown in Figure 2 of the drawing.

Upper and lower gunwale strips 9 and 10 are applied to the eXteri-orsurface of the hull 1' andarespaced from each other in parallel relation. The strips 9 and 10 are preferably of aluminum or other light metal.

A bow piece 11 is inserted in the forward end of the hull and its upper surface is flush with theupper edges of the body of the hull 1. End brace pieces '12 are positioned in the stern corner of the hull ofthe boat and their upper surfaces are flush with the upper edges of the sides of the hull 1.

Hence, it will be seen that the seat boards 5 bear directly at their ends a 'ainst the upper portions of the ribs 2 and the-seat boards 5 rest upon the lower inner gunwale strips 4. Also the braces 6 areupwvarclly and outwardly inclined from the median longitudinal dimension of the hull of the boat and being connected at their ends with the seat boards 5 and the uJper gunwale strips 3 serves to effectually hold the seat boards in proper position upon; the gunwale strips 4 so that the upper edge portions of the hull of the boat are effectually braced and the structure as an entirety .may sustain the pressure of heavy strain against the exterior surface of the hull. The gunwale strips 9 and 10 serve to hold the upper portions of the edges of the hull inwardly toward the ends of the seat boards and the braces 6 and consequently the sides of the hull cannot swerve in consequence of internal pressure or weight carried by the hull. The ribs 2 being of light metal serve to hold the intermediate portion of the hull in proper shape 'so that the same cannot warp or twist in consequence of strain applie interiorly or exteriorly or in consequence of strain due to the propulsion of the boat through the water by the use of an engine or other high power motor.

A floor structure is used in the boat and the said floor structure consists of a forward section and a rear section. The forward floor section includes longitudinally 'dis- 13 are mounted upon the intermediate strips 11 and may be used for holding oars (not shown) upon the floor of the boat or may be used as handles for lifting and carrying the floor section. '1 he rear floor section con sists of spaced strips 1% which are mounted upon cross pieces 15 and as shown in the drawing five strips l i are used; however, a greater or less number of strips may be employed if desired. The floor is made in sections so that the sections may be readily removed from the bottom of the boat for cleaning and painting. The boat may be used for hunting or for any other desired purpose.

From the foregoing description taken in conjunction with the accompanying drawing it will be seen that an aluminum boat of simple and durable structure is provided and that the same has its parts and features so arranged and assembled as to render the structure strong and durable and capable of withstanding the excessive and heavy strain to which it is subjected when in use. Furthermore, the boat is light in weight and may be easily and quickly transported from point to point and may be (prickly launched in the water or withdrawn therefrom.

From the foregoing description of the con struction of our improved device, it will be seen that we have provided a simple. inex pensive and etticient means for carrying out the objects of the invention.

While we have particularly described the elements best adapted to perform the tune tions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be re sorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described the inventiom what is claimed is:

1. A boat structure comprising a hull, ribs disposed transversely thereof in spaced relation, gunwale strips applied to the inner surfaces of the ribs and disposed longitudinally oi the hull below the edges thereof, a seat board resting at its ends upon the gunwale strips and having end edges bearing against the inner surfaces of the ribs and outer gunwale strips applied to the exterior surface of the hull and disposed longitudinally thereof, and opposite the ends of the seat board.

A boat structure comprising a hull ribs disposed transversely thereof in spaced rela tion, upper and lower gunwale strips ap plied to the inner surfaces of the ribs and disposed longitudinally of the hull, a seat board resting at the ends upon the lower inner gunwale strips and having end edges bearing against the ribs, braces connected at their lower ends with the seat board and at their upper ends with the upper inner gunwale strips, outer gunwale strips applied to the exterior surface of the hull and disposed longitudinally thereot', and disposed opposite the ends of the seat board.

In testimony whereof we aflix our signatures.
