METAL BOAT.

SPECIFICATION forming part of Letters Patent No. 433,085, dated July 29, 1890.

Application filed September 6, 1889. Serial No. 323,205. (No model.)

To @ZZ whom it may concern:

Beit known that I, WILLIAM W. KEYS, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Metal Boats; and I do hereby declare the followingr to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the My invention relates to boat-building, but has especial reference to the construction of metal boats, the end aimed at being a strong and simply-constructed boat which shall be perfectly water-tight and which shall present a smooth exterior, unbroken by rivets or bolts.

With these ends in Viewmy invention consists in the details of construction and combination of element-s, such as will be hereinafter fully described, and then specifically designated by the claims.

In the accompanying drawings, Figure l is a side elevation of a boat constructed in accordance ,with my improvement; Fig. 2, a horizontal sectional view at the line of Fig. l; Fig. 3, a longitudinal vertical sectional view; FigA, a cross-section at the line y y of Fig. l; and Fig. 5, a cross-section showing the keel and bottom section cast integral. I

Similar letters denote like parts in the several figures.

A is the keel, to which the bottom sections B are bolted on both sides. The bottom sections C D at the bow and stern are cast each in a single piece, with flanges E F on their inner and upper edges, which extend inwardly, and the intermediate sections B have flanges G II extending inwardly from their lateral and upper edges, the outer lateral O P along their lower and lateral edges, the fianges O being bolted to the upper flanges H of the lower intermediate sections B, while the outer flanges P are bolted to the inner fianges L of the upper bow and stern sections, and the inner flanges P are bolted to each other. The bolting of the flanges forms a water-tight joint, while the flanges themselves constitu-te strengthening-ribs capable of resisting an enormous strain or shock. If desired, the keel may be cast integral with the intermediate bottom sections, as shown at Fig. 5.

I prefer to use cast deoxidized bronze in the construction of the various sections, since such metal has no effect on the magnetic needle of the compass, is not corrosive, does f not require painting, will repel barnacles, is stronger and tougher than steel, and in the end, as scrap, has the market value of copper. I have shown only two intermediate sections and only two tiers of sections; but it is obvious that this invention is not limited in these respects, since the gist ot' said rinvention resides in the broad idea of a castmetal boat made in sections bolted together on the inside, so as to leave an unbroken and smooth exterior.

I claiml. A boat made from cast metal in sections, each section having inwardly-extendi-ng flanges on all its edges which are abutted against adjacent sections, the contiguous flanges of adjacent sections being bolted together, substantially as set forth.

2. A boat made from castmetal sections fitted together by longitudinal and upright joints, the edges of said sections at each ot' the said longitudinal and upright joints being provided with inwardly-extendin g flanges bolted together, substantially as set forth. I 3. In a boat made from cast-metal sections, as described, the upper and lower bow and stern sections, cast each in a single piece and provided with inwardly extending edge flanges which are bolted together, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
