RICHARD S. CHEW, OF SAN FRANCISCO, CALIFORNIA.

SHIP CONSTRUCTION.

a citizen of the United States, residing at the city and county of San Francisco and a State of California, have invented new and useful Improvements in Ship Construction, of which the following is a specification.

This invention relates to a ship construction.

It is the principal object of this invention to provide a ship structure which will be reinforced to resist the various sea actions, and thus permit ships to be built of larger capacity, and yet possess necessary stiffness and strength.

By the present invention the structure is reinforced in such a manneras to efliciently resist any of the sea actions that might tend to distort it, 'as the triangular bulkheads will act to prevent hogging, sagging, torsion or twisting. This construction further provides that the hull of the ship will be subdivided into numerous compartments, a large number of which might be punctured without placing the ship in distress.

The present invention contemplates the use of a ship of timber, steel, or reinforced concrete construction, and, which is formed with a hull of any predetermined design reinforced by a pluralitv of diagonal bulkheads. which are arranged transversely of the ship and crosswise of each other.

The invention is illustrated by Way of example in the accompanying drawings in which- Figure 1 is a plan view disclosing the arrangement of the bulkheads and the prote ted position of the engine room and boilers.

Fig. 2 is a view in transverse section further illustrating the construction.

Referring more particularlv to the drawings, 10 indicates the hull of a ship. This hull may be of anv design, and may be formed of any desired material. In the present instance it is indicated as of timber construction. The height of the ship here shown permits the use of a top deck 11, a middle deck 12 and a lower deck 13. These de ks are supported by timbers 14. The top deck is fitted with a series of hatchways 15, whi h are here shown as divided in quarters, the separating line being drawn from corner to corner diagonally.

In the usual ship construction it is com- Specification of Letters Patent.

mon to extend the bulkheads laterally of the ship and in parallel relation to each other. In the present instance this structure is eliminated, and a series of diagonal bulkheads 16 utilized. The diagonal bulkheads emanate from corresponding points on the opposite sides of the hull and cross each other midship to form a series of rectangular compartments 17 supplemented by triangular compartments 18. Other compartments of irregular shape will be formed at the prow and bow of the vessel. In this manner a series of inclosed compartments will occur throughout the length of the vessel, and triangular compartments will be formed at the sides thereof. The compartments A may inclose the engine room, while the compartments B may be fitted with boilers. This will virtuallv surround the vitals of the ship with a double wall, the inner members of which are inclined, and would act to deflect any projectile or other puncturing member struck thereagainst.

The hatchways are positioned directly over the center of the vessel, and are of sufficient dimensions to allow access to each of the four adiacent compartments surrounding the hatch.

The bulkheads 16 are formed with a set of doors 19, which occur at the point of crossing of the two partition walls. which may he slid upwardlv t provide a passageway directly through the various compartments.

In operation it will he noted that the diagonal bull headsare reinforced to truss the hull ofthe ship a ainst local pressure tending to crush the hull. Furthermore. it will be observed that when the hull is subie ted to a hogging or sagging action the bulkheads will reinforce the entire ship structure longitudinallv, and relieve it from the detrimental effects incident to such strains. As the various compartments are sealed during the transit of the ship, it would be possible for certain of the small triangular compartments to he punctured without placing the vessel in distress.

While I have shown the preferred form of my invention, it will be understood that various changes in the construction, combination and arran ement of parts will be made by those skilled in the art without departing from the spirit of the invention as claimed.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

1. In a ship structure, a hull, and diagonal bulkheads extending continuously and uninterruptedly from side to side of the hull and intersecting each other, said bulkheads being Vertical and extending from deck to deck LO form a series of sealed compartments along each of the ships sides.

2. In a ship structure, a hull, and diagonal bulkheads extending continuously and uninterruptedly from side to side of the hull and intersecting each other, said bulkheads being Vertical and extending from deck to deck to form a series of sealed compartments along each of the ships sides each bulkhead being formed With a pair of openings adjacent and extending outwardly from the point of intersection of the bulkheads,whereby to provide four divergent openings for adjacent bulkheads extending "from a common center, and doors for closing the respective penings.

In testimony whereof I have hereunto set my hand in the presence 01-" tWo subscribing Witnesses.
