LOUIS DOLONE, OF MARSEILLES, FRANCE.

INSUBMERG IBLE BOAT.

SPECIFICATION forming part of Letters Patent No. 647,813, dated April 17, 1900.

Application filed May 19, 1899. Serial No. 717,511. (No model.)

To @ZZ whom, it 11m-y concern.-

Be it known that I, LOUIS DOLONE, a citizen of the Republic of France, residing at Marseilles,Department of BouchesLdu-Rh one, France, have invented certain new and use' ful Improvements in Ships I-Iulls; and I do hereby declare the .following 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 same.

The present invention relates to shi ps7 hulls; and its novelty consists in the construction and adaptation of the parts, as more fully hereinafter pointed out.

The purpose of my invention is to provide a hull which Will when damaged by collision or otherwise be practically impenetrable to water. To this end I construct the hull with double walls, with an intermediate lining-of cork or the like material, which is preferably laid in blocks or slabs, the said blocks being with the broken joints covered by substantially the middle of the next block.

My improved hull construction is clearly illustrated in the accompanying drawings, forming a part of this specification, wherein Figure lis a diagram of a portion of the hull of a vessel, partly in section, showing two ways of carrying out my invention. Fig. 2 is a transverse section of one of the blocks. Fig. 3 is a similar view through a preferred modification.

Referring to the drawings by letter, a designates the inner wall of the hull, and b the outer Wall thereof, both of which may be made of metal or wood, as usual, and be-V tween which the blocks of cork are arranged.

Referring to the construction shown in Fig. 2, it will be seen that the blocks are composed of a plurality of cork plates c, mounted sidewise of each other and secured together by a wooden pin g and to the hull by rivets f. These blocks are square and are intended to be arranged end to end in the hull.

In the modification shown in Fig. 3 the cork lining is preferably arranged in two rows and composed of oblong blocks, the latter` being formed of cork plates d, fastened at one end by wooden pins g. The blocks are here laid inthe fashion ofl bricks, with the broken joints in one row covered by substantially the middle of the next block in the opposite row. As stated, the cork plates d are fastened together at vone end by wooden pins g, and rivets or bolts f are provided, which pass through the walls a Z9 of the hulland through the substantially loose ends of two adjacent blocks, firmly securing the latter in position. i

Of course in practice the plates may be bent or curved to coincide with the shape or' configuration of the hull, as they follow the' continuity of the same, and manifestly the blocks will be thicker in some parts of the hull than in others.

Having thus described my invention, I,

claim- In combination with the hull of a vessel having double Walls forming a continuous compartment embracin g the same, of a filling consisting of a series of blocks of cork ar-A ranged in and adapted to lill the said com partment, and composed of superposed slabs of cork united at one end by wooden pins g, said blocks being arranged in two rows whereby the point of juncture of two blocks in one row is covered by substantially the middle portion of a block in the second row, and united by bolts or rivets f passing through the double walls of the hull and through the substantially-loose ends of the blocks, in the manner herein described and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two Witnesses.

Louis DoLoNE.
