To all whom it may concern-.-

Be it known that I, SALVATORE .Ponzro, a citizen of Italy, residing at Syracuse,- in the county, of Onondaga and State of New York, have invented new and useful Improvements in Unsinkable Boats,.of which the followingis aspecification. i This invention relates to ship construction and has for itsobject the provision .of" means carried by a shipand carrying a plurality of buoys, this means being movable to lie upon the surface of the water in case of injury to the ship whereby the ship will be not only prevented from sinking but also held upright upon an even keel.

An important object is the provision of a structure of this character which includes a plurality of wing-like members pivotally mounted upon the sides of a ship somewhat below the normal water line thereof and normally held in elevated position by suit able cables trained about proper windlasses, these wing members being swingable downwardly onto the water in the event of a mishap, and carrying a plurality of bars which are adapted to be rigidly secured at their upper ends with respect to the ship whereby to prevent folding up of the wings.

An additional object is the provision of a device of this character which will be comparatively simple and inexpensive in manufacture. and installation, which will be highly eflicient in preventing loss of a ship,.and which will be a general improvement in the art.

lVith the above and other objects and advantages in view the invention consists 'in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Figure 1 is an end elevation of a ship equipped with my device, the wings being,

of aship with the in extended position,

Fig. 5 is a plan view with the wings in folded position,

Fig. 6 is a plan view with the wings in extended position, and

mechanism.

Fig. at is a similar view showing the Wings Fig. 7 a detail vieW. Referring more particularly to the'drawings, the letter A designates thehull of a ship and B designates the deck. In carrying out my invention I provide upon each side of the hull a pair of wing members, each of which is designated broadly by the numeral 15. Each wing member comprises a frame formed of transverse bars16 which I are pivotally connected, as shown at 17, with the hull, preferably at a slight distance below or at least adjacent the normal water line. These transverse bars were upwardly and inwardly curved at their outer ends, as shown at 18. Each frame further includes a plurality of longitudinal bars 19 which are secured to the transverse bars 16 and the inner frame is braced by a plurality of diagonally extending bars or the like, 20. Each frame carries a plurality of spaced buoyant members 21 which are preferably hermetically sealed tanks rigidly secured in position upon the frames by any suitable means.

In order that the wings may be held in their normal or upright position, each frame has connected therewith one or more steel cables 22 which are suitably secured to the frame and which are trained about suitable Windlassstructures 23 mounted upon the deck of the ship and provided with the usual operating handle and pawl and ratchet By this means it will be seen that the wing members may be readily maintained in inactive position.

In the event of a collision or any other mishap which results in tearing a hole in the hull of the ship, in order to maintain the ship afloat, it is merely necessary to release the cables 22 by unwinding them from the windlasses 23, whereupon the wing members will descend and engage the surface of the water. As this alone would not be sufiicient to maintain the ship aifoat, it is necessary to provide means for holding the wing members down on the water. In order to accomplish this I provide a plurality of strong steel bars 24 which may be solid or tubular, as preferred, which are pivotally connected, as shown at 25, with the'transverse frame bars 16, and which have their upper ends adapted to be forced into retaining members 26 mounted either u on the deck or upon the sides of the hull; ad acent the deck. It will be seen that when these bars 24 are pressed position.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided readily operable and easily oontrolledmeans which may, in an extremely short time, be moved into such position as to support a ship in the event of damage to the hull thereof which might cause danger of sinking. a a

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, andarrangement of parts as will not depart from the spirit of the invention Having thus described my invention, I claim:

Incombination with the hull of a ship, a buoying device comprising a plurality of frames pivoted upon the hull adjacent the the hull of the shipnear the deck line and pivotally connected with the frame, each of sald brace bars belng ]01Ilt6(l lntermechate its ends by means of a rule joint, the function of said brace bars being to hold said frame in substantially horizontal position when in use. i

In testimony whereofI afiix my signature.

' SALVATORE PONZIO.
