-JOHN B. SARDY, OF NEV YORK, N. Y.

Specification forming part of Letters Patent N o. 34,165, dated January 14, 1862.

To @ZZ whom t may concern.-

Be it known that I, JOHN B. SARDY, of 58 South street, in the city, county, and State of New York, have invented certain new and useful -Improvements in Ships of War and other Vessels; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side view of a vessel of war constructed according to my invention; Fig. 2, a view looking directly toward the stern of the same; Fig. 3, aplan of the gun-deck; Fig. 4f, a central longitudinal section; Fig. 5, an inverted plan, and Fig. 6 a transverse section t-aken in the plane indicated by the line :c a: in Fig. 4.

Similar letters of reference 'indicate corresponding parts in the several figures.

In war-vessels built according to the plans and models at present in use clad with iron or steel armor-plates and propelled by steam, unless they are of too small size to be safe and formidable sea-going vessels, it is impossible to obtain carrying capacity sufficient for the battery and for machinery powerful enough to obtain high speed, with coal enough for several days service, without so great a draft of water as renders it impracticable for them to enter most bays, harbors, rivers, and other inland waters.

The principal object of the first part of this invention is to overcome this difficulty', and to this end this part of the invention consists in the construction of a Vessel with what may be termed a double-inclined stern-that is to say, with two stern-posts having between them a double-inclined run commencinginthe after body of the'vessel and a midship-keelby which construction I am enabled to make the vessel with a very fiat floor and greater width of beam extending very far aft, and so greatly increase the buoyancy and carrying capacity, while I do not interfere with the propelling or steering qualities of the vessel, but, on the contrary, afford better provision for the use of two screw-propellers and two rudders attached to the stern-posts. The same construction is also applicable with corresponding advantage, so far as lightness of draft, speed, and carrying capacity are con sidered, to vessels for other than war purposes.

The second part of the invention consists in the construction of a vessel, for the purpose of making it serve as a battering-ram against other vessels or structures, with a pointed prow terlninating at or near the water-line and having an inclination in every direction-viz., upward and downward and laterally toward the bow of the vessel-such yprow not being simply put on the outside of the vessel, but being built with and forming a part of the vessel, and thereby having great strength and stability. This prow is to be covered with iron or steel armor-plates and heavily clad with steel at its point.

The form of the double-inclined stern is illustrated in Figs. 2, 4, 5, and 6.

ct a are the two stern-posts, and b b the double-inclined or central runs, corresponding nearly in form with the outside runs c c. The stern-posts a ct combine with two parallel keels d d, which may extend the whole or any portion of the length of the vessel.

e is the central or main keel, extending the whole length of the vessel and having in the after part of the vessel an inclination from where the double inclined or central runs c c commence upward to the stern.

The pointed prow is illustrated in Figs. l, 3, and 4, by a comparison of which it may be seen that the said prow is inclined or tapered in every direction bottom, and sides. This prow is built out as a portion of the hull ot the vessel and made 0f or lled with solid timber for some distance back from its point.

I propose in building vessels of war to have the sides inclined toward the center from the water-line upward, as shown in Figs. 2 and 6, to cause the glancing olf of projectiles which may strike them; also, to throw the weight under the center of motion, and I also propose to have an iron or steel plated bomb-proof deck f, covering the gum-deck g, with suitable and adequate means of ventilation and carrying away the smoke from the guns.

What I claim as my improvement in the construction of a mau-onf-war ship or other navigable vessel isthat is to say, on its top,

1.l The combination of two or more stern- @lined runs b b, substentiztllyes heren'speciposts a, a, two or more keels cl d, and two or ed. more propellers hh or other motors revolving v3. The pointed proW tapered in all direcin the same Vertical plane, construct-ed and tions when used in a 11u11, as before described.

operating in the manner and for the purpose described, in order that greater buoyancy, JOHN B. SARDY. speed, and capacity may be obtained. Witnesses:

2. The combination of the central keel e RICHARDSON GAWLEY; with keels d l and propellers h 77, and n- JAMES LAIRD.
