SUBMAJBJINE-FENDER.

Application filed June 9, 1917.

To all whom it may concern:

Be it known that I, IsRAiaL LEVY, a subject of the King of Hungary, resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Submarine-Fem ders, of which the following is a specification.

This invention relates to improvements in submarine fenders as applied to the exterior of seagoing vessels.

The principal object of the invention is to provide a plurality of sectional fenders so arranged with relation to the hull of a vessel, both above and below the water line, as to render the same substantially immune against attacks by torpedoes, mines, bombs, and the like.

A further object is to provide such fenders of relatively small sectional area, so that should damage occur to any particular one, the others will be maintained in operative condition.

A still further object is to provide such tenders in forms which may be readily aplied to vessels already built as well as to be installed originally.

These and other like objects are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this, disclosure, and in which Figure 1 is a side elevational view indicating a conventional type of sea-going vessel to which the invention is applied.

Fig. 2 is a top plan view of the same.

Fig. 3 is an enlarged fragmental top plan view showing the arrangement of a single plate fender.

Fig. 4 is a transverse sectional view taken on line H of Fig. 3, and

Fig. 5 is a partial vertical sectional view taken on line 55 of Fig. 3.

In the drawings, the hull of a conventional vessel is indicated by the numeral 10, to which is attached in vertical rows, a plurality of plates 14, from which extend the tubular stems 15, provided with partially closed ends 16, through which spindles 18 are slidably engaged, the spindles having upon their inner ends, within the tubular stems 15, enlarged heads 19, thereby limit ing their outward movement.

Specification of Letters Patent.

Patented Nov. 29, 191?.

Serial No. 173,703.

These stems 18 are engaged at their outer ends with rigid rectangular plates 20, adapted to receive the impact of the blow, as from a projectile. the blow being transmitted through coiled push springs 21, encircling the hollow stems 15 and spindles 18 in an obvious manner.

Also secured to the hull 10 of the vessel, intermediate of the plates 14, are a plurality of cups 24, the same having disposed at their lower or bottom ends elastic cushions 25, covered by a circular disk 26, the cups also receiving the lower ends of springs 28, the outer ends of which are engaged with plugs 29, rigidly set in the inner side of the plates 20, thus effectually interposing a spring resistance between the plates 20 and the hull of the vessel sutlicient to soften the blow or impact of a projectile, and ultimately retard the same to such an extent as to prevent damage to the vessels hull.

From the foregoing, it will be seen that a plurality of the protective devices are secured to the vessel side completely surrounding the same and in such manner that each may work individually without conflicting with those adjacent, the plates at the ends of the vessel being arcuately formed or an gular in order to suit its contour, thus providing effective protection.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a vessel fender, the combination with a plurality of rigid fiat rectangular plates arranged in plural rows, both horizontally and vertically, stems engaged with said plates, tubular elements secured to the walls of the vessel in which said stems are engaged, springs encircling said tubular elements and stems exerting an outward pres sure upon said plates, means for limiting their outward movement, a plurality of cup elements interposed between said tubular elements, elastic cushions contained in said cups, and springs extending between said cup elements and said plates adapted to cushion their inward movement.

In testimony whereof I have ai'fixed my signature.

ISRAEL LEVY.
