vision of means whereby a torpedo directed a against the hull of a vessel may be seizedand held so to avoid injury being den@ to the ship.

A further object is to provide torpedo rearranged aloi'igside the shipsl hull, made of flexible, pliable material so as to avoid detonating a torpedo coming in contact, preventing explosion of the same.

'lhese and other like objects are attained by the novel construction and combination described and shown in tcrial part of this specification, and in whichl Figure 1 is a side elevational view of a conventional type of ship showing the application of the invention.

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

'In the drawings, the ship, indicated by the numeral 10, is of an ordinary type of construction and has rigidly engaged to its hull two horizontal rows of laterally extending, horizontalk bars lil, having nuts 15, rigidly holding plates 16, through which :ire formed a plurality of uniformly spaced circular openings i7, in which are plugs having cylindrical bushings 18, the same being Hush or level with the inner sides of the plates.

Extending enlarged cylindrical heads 20, are formed with the bushings, the shoulders 19 resting upon the opposite outer sides'of the plates, while conical openings 2l, suited to receive the front end of a torpedo extend through the plugs, which are made of rubber or other elastic, pliable material and are arranged so that their peripheral edges are juxtaposed, forming a plurality of inclined surfaces receptive of the end of a torpedo which may enter and extend through the openings 22, to the inner side of the plates. ris these several plugs are circular in their cross-section, at the triangle formed between any group of three plugs, raised triangular posts 2d, are set in the plate, the side and end angles of the posts beingfshaped in conformity with the beveled interior of the plugs, so as to present a substantially unbroken, continuous surface adapted to receive and divert the point of an incoming torpedo into any of the several openings.

ln the modification shown in Figs. at and 5, the plugs are formed with like bushings 17, fitted to the circular openings formed inl the plate, while the heads 30, are rectangular ,and suited toclosely Contact one with the other.

The interior beveled surfaces are so arranged4 as to` present substantially no tlat space against which the point of a torpedo might strike.

rlhese plugs are also made of relatively soft, pliable material into which the points of a torpedo may enter without damage to the vessel or to the torpedo, which may be recovered when its propulsive force is expended, and it will be evident from the foregoing that as the plates containing the plugs extend from a line slightly above the water level to a line below the keel, that any torpedo aimed at the vessel along the side will loe received and retained, thereby preventing damage to the vessels hull.

in the modified construction shown in Figs. Z to l1 inclusive, a plurality of brackets 35 are secured tothe hull 10 of the ship, other brackets 36 being arranged at the ends. Extending from the brackets 36 are outsecuredv standing projections 37, corresponding to A'projections 38 from the brackets 35, which have attached to them arms 40, byV means of pivot screws' 4l, similar screws 42 con-V necting the arms 43 with' the brackets 36.v The arms 40 areY joinedby pivots 44 to 'studs Y 45, rigidly secured to the plate v48', similar in all respects to Vthe plate 16, except that the plate 48 may be attached at vulnerable partsof thefship rather VY than extend over Y AtheY entireY side.V

5 Iiiorder 'thatthe plate 48 may be brought" closely adjacent to the hull Vofthe vessel when desired, hand screws 49, are used to Y connect the end-arms 43fwith thefplate,the Vsame beingjnormally engaged withprojectionsv 50 at oneV end, and withthe innern most opening in a 'bracket 52V at thev other end, .inV such manner that tliejarm may be the` arrangement of pliable bushings remain moved from one opening to. cated best in lIfigs.l 7 and 8.V

At the same time the otherY arm may be engagedin a post. 53, Vset in the plate 48, thereby holding the plate closely` adjacent to the side of the' vessel, it being understood that another as indiarranged in two rows respectively near thef y-top and bottom of said hull, a

plate rigidlyj said arms, said plate of Vuniformly spaced securedV at the ends of containing a plurality openings, pliable plugs secured in said openbases of saidl ings, *the outer Vsurfaces of said plug being closely'adjacent one to another, and a conical opening formed in each of said plugs', the

openings Ybeing outward.

' 2. Ink a submarine fender, the combination with a plurality .ofrigid arms arranged in two rows at the top and bottom ofthe ships hull, said arms extending horizontally outward upon either'side thereof, and rigid plates engaged at the outer ends of `said arms, of aplurality of uniform open ings formed Vthrough said. plates, pliable 'bushings secured inthe mentioned openings,

enlarged heads formed with saidA bushings,

the periphery of said heads ,being closely'adi jacent` to one another, Vconicalv openings exopenings being outward, and means affixed in said plates adapted to: direct articles into saidV openings.

In'azsub'marine fender, the combination with a plurality ofarms pivotally attached vto the hulljof a vessel, extendingloutward' therefrom, and a rigid plate secured at the ends of said arms, ofa'pair of arms at the seAV ends of said plates, said arms pivotally con- Y nected between said plateand the hull ofthe ship, and means by which saidv arms may bev attachedV to,` differentpoints on saidV plate,

so as to hold said plate in an extended posi'- tion orrallow it. to be folded alongside the hull of said ship. Y v

plurality of openings through said plate,

to be intimately in contact, beveled openings pliable bushings secured in said Y openings, said bushings being so arranged as formed in 'said bushings, theouter edges of said openings presenting sharp lines'at their junction at both sides, top and bottom thereof, pivoted arms connecting between the hull of said ship, and the ends of ysaid plate,and means for permit said plate toY be disposed closely adjacent to the hull ofthe ship, lorfezlitended therefrom.
