BOAT.

W Specification of Letters Patent.

Patented Mar. 27, 1917.

Application filed January 26, 1916. Serial No. 74,375.

To all whom it may concern: I Be it known that I, GEORGE 'W. Bron/Ann- SON, a citizen of the United States, residing at South Hero, in the county of Grand Isle and State of Vermont, have invented certain new and useful Improvements in Boats, of which the following is a specification.

My invention relates to new and useful improvements in boats and more particularly to the hull construction, the primary object of myinvention being the provision of a boat which will encounter the least possible water resistance and which will be of light draft for its size and weight.

A still further object of my invention consists in constructing a boat hull of the above described character in such a manner that the faster the boat is going the less its draft will be.

In accomplishing the above objects I construct a boat hull having substantially vertical sides and a flat bottom curved upwardlyat its ends, the sides of the boat being provided at their ends with forwardly and rearwardly projecting extensions or wings. Because of this construction, I accomplish a still further object, namely, the provision of a boat hull of such a type as to prevent the setting up of side waves. For this reason, my boat is particularly adapted for use in narrow or shallow streams so that it will not interfere with other boats and will not wash the banks of the stream as ordinary boats do because of the setting upof side waves.

A still further object of my invention consists in providing the side of the boat with downwardly directed extensions projecting not only throughout the entire length of the boat but throughout the length of the wings and forming in eifect bilge keels of substantially the same depth as the main keel which extends longitudinally of the center of the boat. Because of this arrangement, the boat, if grounded, will rest upon a comparatively even keel and will will not turn over. 7 5

A still further object of my invention consists in the provision of a superstructure upon the prow of the boat in the form of a wedge shaped wave breaker in order that in rough water the wave may not offer too great a resistance to the progress of the boat.

Obviously, this superstructure may be omitted from boats intended for use in land locked waters.

1th these and other objects in View, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this application.

In the drawings:

Figure 1 is a perspective view of a boat hull constructed in accordance with my invention;

Fig. 2 is a bottom plan view of the hull shown in Fig. 1;

Fig. 3 is a central longitudinal sectional view of the hull;

Figs. 4 and 5 are vertical transverse sectional views taken on the section lines H and 5-5, respectively, of Fig. 3;

Fig. 6 is a side elevation of a somewhat modified form of ship hull construction, particularly adapted for use in the building of battleships;

Fig. 7 is a corresponding View of a still further modified form of hull construction;

Fig. 8 is a fragmentary perspective view of the bow of a still further form of hull construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

As will be best seen by reference to Figs. 1 and 2 of the drawings, my improved boat hull issubstantially rectangular in shape including parallel spaced side walls 10 connected by a horizontal bottom wall 11, the rear end of which curves upwardly somewhat, as at 12 to merge with the rear wall or stern and the forward end of which is curved upwardly, as shown at 13 to merge with the vertical front or bow wall 14 which extends at right angles between the side walls with its lower edge located at substantially the water line of the boat when the latter is normally loaded. The side walls 10, at substantially the water line, are provided throughout the greater portion of their length with outwardly projecting ribs or buffers 15 which protect the boat from injury by rubbing against what-"es or other boats 'and which also serve, to some extent,

proved to check rolling of the boat in rough water. As clearly shown in the drawings, the lower edges of the side walls 10 project below the bottomwall 11 and the ends of the side walls are extended at the front and rear of the boat to provide wings 16, the free ends of which are substantially vertical. These downwardly extending edges of the side walls of the boat hull in effect form bilge keels and the flat portion of the bottom 11 of the hull is preferably provided centrally with a longitudinally extending main keel 17 which may be of the same depth as the bilge keels or which, as in the case of the drawings, may be somewhat deeper.

The upwardly curved forward end 13 of the bottom of the hull may be provided in longitudinal alinement with the main keel 17 with a V-shaped groove 18 in order that water rushing through this groove may, to a certain extent, have the same effect upon the movement of the hull laterally through the water as would a keel. Preferably, however, the main keel 17 is extended at its forward end to provided a Win 19 which corresponds in shape and size to the forward wings of the bilge keels. This manner of extending the main keel is clearly shown in Fig. 8 of the drawings, the construction of the hull shown in such figure, with this distinction, being identical with that shown in Figs. 1 and 2 of the drawings.

From the foregoing description of my imboat hull, it will be clear that movement of the boat through the water will not cause any forcing of the water away from the sides of the boat as the sides of the hull are vertical and parallel throughout their entire extent. On the other hand, all water disturbed by the passage of the boat is in effect forced downwardly beneath the bottom of the boat and tends to lift the boat higher in the water, thereby decreasing its draft and also decreasing the resistance which it oifers to the water. Because of this taking in of the water at the bow and discharging it at the stern, all side wash or set ting up of side waves is prevented. This is an important feature, particularly if the boat is to be employed upon rivers or canals as the side wash is oftentimes dangerous to smaller boats and, in canals, tends to break down and destroy the banks.

If the boat is to be employed in large bodies of water where the waves will run high, it may be provided with what 1 term a wave breaker which is indicated as a whole by the numeral 20, being best shown in Figs. 1 and 2 of the drawings. This wave breaker is wedge-shaped in horizontal section, has its bottom wall 21 horizontally disposed at substantially the water level of the boat and has downwardly and outwardly diverging top walls 22. The rear of the wave breaker of course projects between the spaced forward wings 16 being integral with or secured to the front wall of the boat and the forward portion of the wave breaker extends a considerable distance in advance of the wings as clearly shown in Fig. 2. As will be readily understood, with this wave breaker any waves striking the boat head on wiill be split and the water deflected to the s1 es.

The above boat may, obviously, be driven in any of the ways now in common use, such as by propeller wheels disposed at the sides of the hull or by a screw propeller such as shown in the drawings at 25. A rudder may be of the hull, at the center of the stern and bow of the hull or two rudders may be secured one to the rear end of each of the wings 16, as shown'at 26 in Figs. 1 and 2. Preferably, at least two rudders are employed to facilitate turning of the hull in a relatively short distance and in many instances I find it advisable to employ four rudders, as shown at 26 in Fig. 7 of the drawings, free edge of each of the wings at the front and rear of the boat. With the exception that the boat shown in Fig, 7 is provided with four rudders, the hull construction there shown is the same as that previously described. Forward rudders'somedisposed at the center of the stern a rudder being mounted upon the what smaller than the rear rudders may be 7 employed with boats having wave breakers if desired.

In Fig. 6 I have illustrated a somewhat modified form of construction in which the front and rear wings 27 and 28, respectively,

are extended forwardly and rearwardly to a greater extent at their lower edges in order that the forward wings may in effect form a double ram and the rear wings an ample guard for the propeller. Otherwise,

the general design of the hull shown in Fig.

be apparent that with a main principle of my invention, namely, the

provision of a boat hull having substantially vertical parallel side walls extending beyond the ends of the hull to provide wings and having a bottom wall curved upwardly at its ends and spaced somewhat above the lower edges of the side walls. For this reason I reserve the right to make any changes within the scope of the appended claims without in the slightest degree departing from the spirit of my invention.

Having thus described the invention, what is claimed as new is:

1. A boat hull including vertical, parallel side walls, a bottom wall disposed between the side walls and at a level above the lower edges of the side walls, the side walls being extended at their forward ends to provide wings and the bottom wall being curved upwardly at its ends, end walls disposed between the side walls and connected to the upcurved ends of the bottom wall and spaced inwardly from the free edges of the wings, and a wave breaker disposed between the upper portions of the forward wings.

2. A boat hull including vertical, parallel side walls, a bottom wall disposed between the side walls and at a level above the lower edges of the side walls, the side walls being extended at their forward ends to provide wings and the bottom wall being curved upwardly at its ends, end walls disposed between the side walls and connected to the upcurved ends of the bottom wall and spaced inwardly from the free edges of the wings, and a wave breaker disposed between the upper portions of the forward wings,

Copies of this patent may be obtained for five cents each, by addressing the said wave breaker being wedge-shaped horizontally and having a fiat horizontal bottom wall and downwardly and outwardly diverging top walls.

8. A 'boat hull including substantially vertical and parallel side walls, a bottom wall disposed between the side walls and at a level above the lower edges of the side walls, the side walls being extended at their forward ends to provide wings and thebottom wall being curved upwardly at its ends, and a wave breaker disposed between the upper portions of the wings and extending in advance thereof.

4;. A boat hull including substantially vertical and parallel side walls, a bottom wall disposed between the side walls and at a level above the lower edges of the side walls, the side walls being extended at their forward ends to provide wings and the bottom wall being curved upwardly at its ends, and a wave breaker disposed between the upper portions of the wings and extending in advance thereof, said wave breaker having downwardly and rearwardly diverging upper walls.

In testimony whereof I aifix my signature.
