SAFETY-BOAT.

Specication of Letters Patent.

Patented Mar. id, MHG.

To all whom 'it may concern.'

Be it known that we, HYRPOLYTF. M. CHIRON and JEAN F. BERRIEX, citizens of the Republic of France and the United States, respectively, residing in the city and county of San Francisco and State of Caliornia, have invented a new and useful lmprovement in Safety-Boats, of which the following is a specification.

Our invention relates to safety boats wherein an inner hull is supported, surrounded and vthereby protected by means of an outer hull consisting of separate compartments and having overhanging portions adapted to maintain the equilibrium of the boat and also to protect the same against collision and torpedo attacks; and the objects of'our invention are,kirst, to provide an improved boat adapted to withstand attacks from torpedoes and the like; second, to provide improved means adapted to main tain the boat on an even keel; third', to provide improved means adapted to prevent the iiooding of a compartment when the same has been penetrated from without,l

and, fourth, to provide a construction that shall be adapted to minimize the danger of sinking when the hull has been perforated. YVe accomplish these several features by means of the preferred form ot' the invention disclosed in the drawings forming a part of the present speciiication wherein like characters of reference are used to designate similar parts throughout the saidl 'hull removed. Fig. 5 isa horizontal longitudinal sectional view taken on line Y-Y or" Fig. l of the drawings. Fig. 6 is a horizontal sectional view taken on line Z-Z of Fig. l of the drawings". Fig. 7 is a transverse sectional view taken on line V-V of Fig. l ol the drawings.

Referring to the drawings the numeral l is used to designate an inner hull consisting of a lower portion 2, substantially open, and an upper portion 3 divided by means of decks 4 in the usual manner so as to provide space for state rooms and the like. The spaces between the decks 4 are again divided into separate compartments by means- `of double bulkheads i3 and the upper por` tions of the bulkheads T. rlhe bulkheads are arranged with a space between whereby access may be had to the hold of the boat. The lower portions of the bulkheads 7 are used to divide the lower portion 2 of the inner hull l into separate compartments which may be used for stoke holes, an engine room and the like.

Baggage may be lowered into the lower l compartments l5 when penetrated from without.

A series of columns i8 are provided just beneath the double hulklieads 6 so as to properly support the decks fl.

Should the bow oi the boat collide with an object it is obvious that while the front of the boat may he crushed and the compartments l5 penetrated the air tight empty cans or receptacles l@ will prevent the ilooding oi' the said compartments and thereby tend to prevent thesinking of the boat. The double side and bottom portions of the outer hull 9 being composed of the compartments 17 will obviously tend to prevent a penetration of that portion of theboat by reason of said double construction and compartments. As the overhanging portions ll are of considerable weight it is evident that said overhanfring portions l1 will tend to maintain the equilibrium of the boat.

It is also obvious from the foregoing that wehave provided improved means adapted to'withstand attacks fromtorpedoes and mines as well as an improved construction adapted to prevent the flooding of the penetrated compartments due to a collision.

The details of construction' are so susceptible to variation that we do n'ot wish to confine. ourselves to the precise construction shown herein but rather to availt ourselves of any modification that may fall properly within the scope of our invention.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is` A safety boat comprising an inner hull 5 having an upper portion divided into decks and a lower open portion; double transverse lbuikheads arranged. to divide the upper and lower portions of the inner' hull and to provide access to the hold thereof; and an outer 10 hull arranged around the inner hull and having tiers of compartments therein, and

In Witness whereof We hereunto set our `15 zl signatures.
