SHIP-FENDER;

speciaeation of Lettersratent.' Y. Patented` Mar. 1.1,A 1919.

Application filed July 19, 1918. Serial No. 245,615.

To all whom it may concern:

Be it known that I, PRoKoFY KUHARCHEK, a citizen of Russia, residing at Jerome, county of Somerset, and State of Pennsyl- Vania, Improvements in Ship-Fenders, of. which the following is a specication. V

This invention relates to improvements in ship fenders and particularly to types adapted to defend the ship against the attack of torpedoes, mines and like undersea projectiles. n

The principal object of the invention 1s to provide a 'fenderV comprised of resilient elements adapted to receive the impact or blow of a projectile, whenin an operative position, soas to eifectually prevent damage being done to the hull of the ship.

A further object is to provide means whereby the fender may be raised or retracted when not in use so as not to impede the progress of the ship through the water.

A still further object is to provide a fender comprised of few and simple parts, easily operated and readily applled.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which 'Figure 1 is a fragmentary top plan view, showing a conventional type of ship and indicating the attachment of the invention.

Fig. 2 is a side elevational view of the same.

Fig. V3 Vis a transverse vertical sectional view,`taken through a portion of the hull of the vessel and the `fender elementsl employed, and

F'g. 4 is a perspective fragmentary view showing a modified form of the fender elements.

Engaged with the hull of the ship 10, here conventionally represented, and possessing all of the necessary paraphernalia for propulsion and navigation, are extending lugs 14, the same being arranged at spaced intervals in two horizontal rows around the hull and pivotally engaged in them are link bars 15, the same operating in the manner of a hinge and adapted to extend Vhorizontally outward when in an operative position, fromv the hull of the ship. l Y

These bars engage with similar lugs 16 carried by rigid rails 18, arranged in'rows,

have Vinvented certain new and useful i v'parallel' with the central line of the ship and at a considerable distance therefrom, according to the length ofthe connecting bars 15. Y

Extending between the pairs of rails 18 are a plurality ofV coiled springs 1 9, the same being arranged in spaced vertical relation. along the entire length of the supporting rails 18.

Fixed upon the deck ofl the ship are Winches 20, operating drums 21, to which are attached cables 22, the cables passing over pulleys 23, mounted upon the upper .l

ends of vertical posts 24, secured upon the` hull of the ship, the cables ultimately Vbeing connected, at their extreme outer ends,

Y with the upper rails 18 in such manner that when the drums are rotated, the cables will be wound thereon and the arms l5, together with the springs 19, raised into the position shown in the broken lines in Fig. 3, thus elevating the entirevstructure, which normally extends downward into the water in which the ship floats, to such an extent as to offer no impediment to the progress of the ship.

In the modification shown in Fig. 4, the same identical construction is used with the addition of vertical bars 30 pivoted on pins 31 to the bars 15, and extending between the vertical bars 30 are aplurality of horizontally disposed helical springs 32, thus forming a net work, the elements of which are n spaced Auniformly apart.

As a furtherl protection, a woven net 33 is suspended at its corners by the pins 34 to the bars 1K5 so that should a torpedo or like projectile pass the springs 19 and 32, in addition to its being retarded thereby, it willbe prevented from close approach to the hull Vof the ship, due to the net 33, this arrangement, like that previously described, being readily raised completely out of the water by actuating the Winchesl 20.

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

In a ship fender, the combination with the Y being eorinected with the uppermost'of said' otallyseoured between said link bars, other coiled springs arranged horizontally and' e'ngaged at their en ds with said vertical bars,

and a meshed` net pivotall'y engaged with saidV linkbars, allxof sa-i'd bars, Vsprings and'nets being' raisedl upon the operation of'said 10r Winches, allv substantially shown and de-V Y scribed. f Y VIn testimony whereof I have Yaixed my Y* signature.

Y PRoKoFY KUHARCHEK Copies of' this patent may be obtained forY five cents each, by addressing they Commissioner of Patents, Y Washington, D. C. Y.
