ANTSUBMAR-INE DEVICE.

Application filed August 6, 1917.

To all whom may concern s Be it known 'that l, HARRY LEMISZCZAK, a subject o the Emperor oi Austria, resident oi Yonkers, countyv of lVestohester, and- State oi New York, have invented certain neuv and useful linprovenients in Autisubinerme Devices. of which the following 1s a i specification.

This invention, relates to improven'lents in protecting devices for the hulls of vessels, and has as its special object the provision of means which may rapidly. be suspended iironi the hull of a vessel and arranged to iorni an effective guard against torpedoes and the lilre, Which are prevented from causnre; damage to the vessel.

ri"his object attained by the novel construction and combination oi' parts here after o escribed and shown in the accom-A panj/'ine' d Iavvings, iorniinga material part oi this disclosure, and in which- Figure l. is a side. elevational View of a conventional type of vessel indicating the application of the invention.`

lil 2 is a fragmental vier7 ci' one of the dcliectingplates, the view beingitalen substantially en line of Fi( Fig. is a transverse va cal sectional view talren on line 3-3 of li l.

Fig'. is a top plan view illustrating the application of guard plaies to a vessel.

5 is a ragniental verti al sectional view similar to 3. b'utshovving a inediiieaiion in construction.

Figi. tl sectional viev of taken on line "l" is i i'ragniental side elevational vi( y oil the seine.

. ,il 8 is a transverse vertical vi W talren 8 8 of Fig. Q and 9 is a perspective vieu.' looking from r side oi one oiz the guard plates. iis it obi/'ions that au armor plate disposed at a distance from the Walls oi' the will iin; de its movement through is'deei. l advisable to provide plates in rorins which may be readily attached to the gunwales of a vessel in time of need. and which ma;V normally be carried.' upon 'the v Alsel itself.

'The prese; 'Wen on comprises a plu rectangular' arinor l0, adapten to be suspended by straps the saine being,1 hooked-shaped and adapted to over the top e of the vessel so as to han@ pendently beside the the saine Specification of Letters Patent.

Patented Feb. 18, 1919. serial no. 134,691.

hull 13, and in order to provides desirable degree of resilience to the plate it), a plurality of arcuate or elliptical springs l5 are attached by rivets 16 to the plateupon one side, the springs being disposed one above the other in a vertical row in such manner that the opposite side of the spring will make contact with the vessel hull 13, so that if the plate l receives the shock or impact of a projectile, a certain amount of resilience is obtainable, tending to cushion the blow transmitted to the walls of the vessel, and it will be obvious that the armor plates are substantially straight along-'the sides and bent in conformity with the outline of the vessel at the stern and bow thereof.

In place of the elliptical spring l it may be preferred to use the device shown in Figs. 5 and G, in which a pluralityv of resilient contact elements 20 are irinly engaged to the plates 1S the edges 2l `and 22 of the plate being beveled and arranged in vertical rows in the manner of the scales of a fish, the edge of one slightlyv overlapping that of the sueceeding plate.

In order t0 hold these plates in relation with the sides 13 ot' the vessel, a plurality of bolts 23,; are alixed in the Walls of the vessel, the' saine extending through the plates 18 and secured in position by means of the nuts 24, there being disposed between the walls 13 of the vessel and the plates 1S, spira-ily coiled compression springs 25, the saine e circling, the Shanks of the bolts 23.

ln mis forni, each of 'the plates is independently suspended and so held as `to be able to nieve in toward the vessel until the springs and resilient elements have absorbed the shock or blow.

iin 7 to 9 inclusive a soniewha-te simiM lar arrangement of sectional plates is iii-:iicatcd, each oi' the plates 30 having beveled Ydges and a central opening 82, receptive of the reduced stein 35, of posts 36, supported by brackets 37, secured by screws 38 or the like to the wall i3 of the vessel, the posts l'izwing` shoulders against which the inner side of the gllard or armor plates ulalie contact and which are held in posilion by means of the nuts lli), all of these several guard or armor plates being' Ytorined with rigid projections l2 at their corners, the inner rounded points ci which make contact with the vessel hull, presenting in eil'ect a substantial, rigid outer casing for the vessel.

From the foregoing it will be seen that a .substantial arrangement for protecting the hulls of vessels has been disclosed.

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

In a sliips armor of the character described, the combination of a plurality of centrallyT perforated plates having beveled edges, with posts adapted to space and hold said plates apart from the ships hull, reduced stems on said posts passing through the perforations of said plates, brackets on lessee@ HARRY l'iEMSZGZAK.
