ATTACHMENT FOR BOATS Filed April 8, 1931 INVENTOR W W mamas E atented Jan. 5, 1932 LIL) . UNITED STATES PATENT OFFICE GEORGE W. CABLE, OF LA JOLLA, CALIFORNIA ATTACHMENT FOR BOATS Application filed April 8, 1931.

The object of this invention is the provision of a prow for flat bottom boats whose sides are rounded to the bow thereof, of a construction which will greatly facilitate the speed of the boat as the same cuts or parts the water to direct such water against the sides and not under the bottom of the boat and which is provided, at its sides, adjacent its front and its rear portion, with openings through which air, water or both air and water will pass to create a suction at the bottom of the boat, and drain the prow to render the same lighter and also overcome friction by the introduction of air bubbles near the bow directly below the bottom of the boat.

I A further object is to improve the prow attachment for boats upon which I have received U. S. Letters Patent No. 1,7913%, granted me Feb. 3, 1931.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a side elevation of the bow portion of a flat bottom boat equipped with the improvement.

Figure 2 is a bottom plan view thereof.

Figure 3 is a central longitudinal sectional view therethrough.

Figure at is a sectional view approximately 0n the line t& of Figure 1.

In general the prow construction is similar to that of my patented device. The prow 1 is of metal and is designed to be attached to the forward end or how of a flat bottom boat. The bow from the bottom of the boat is arranged at the usual inclination, as indicated by the numeral 2 and my improvement is designed to be attached to the sides, front and bottom of the bow. The improvement is preferably constructed of metal but is hollow. The improvement includes inclined side walls 3 which have their upper edges riveted,

as at 4, to the sides of the bow of the boat. The sides merge into a point and from this point extends the bottom 5 of the prow. The rear of the bottom is fiat to correspond with the shape of the bottom of the boat 1 and is riveted thereto, as indicated by the numeral 5. The sides, adjacent to the forward end and Serial No. 528,666.

top of the prow l are provided with openings 6, and these openings are surrounded by outwardly extending funnel-shaped members 7. The flat bottom portion of the prow is also provided with a series of laterally arranged openings, each of said openings being surrounded y a rearwardly arched pipe in the nature of a nozzle 8. W ith my present construction of prows for boats water will enter the funnels 7 when the boat is propelled through the water and this water will find an outlet through the pipes or nozzles 8 at the rear and at the bottom of the prow. This creates a suction while the boat is under way and will completely drain the prow of water,

thereby making the prow lighter and enabling the same to resist the friction of the water against the bottom of the boat as air bubbles are created in the hollow prow and are directed through the nozzles against the flat bottom of the boat.

.t is thought the foregoing description will fully and clearly set forth my improvement and the advantages thereof so that further detailed description will not be required.

Having described the invention, I claim:

An attachment for a flat bottom boat consisting of a. prow shaped plate having edge portions adapted to be attached to the sides and bottom of the end of the boat, said plate being provided at its sides with inlet openings and at its bottom with rcarwardly disposed ends of which are located below the bottom of the boat when the prow is applied thereto.

In testimony whereof I affix my signature.

GEORGE W. CABLE.
