To all whom it may concern.-

Be it known that I, MIOI-IE'LE CIGANENKO, a subject of the Czar of Russia, resident of S. S. Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Tor pedoltepelhng Devices, of whlch the followingis a specification.

This invention relates to improvements in torpedo repelling devices, as attached to the hullsof vessels when Within a danger zone.

The principal Object of the invention is to provide devices extending longitudinally of the vessePsside andat a considerable dis tance therefrom, or which may. be folded compactly against the hull.

A; further object is to provide means at the rear or stern of the vessel which may be con'ipletely' raised out of the water when not in use, thereby avoiding. impediment during navigation.

Theseand other likeobjects are attained by the novelconstruction and combination of parts hereafter described and shownin the accompanying drawings, tor-ming e material part of this disclosure, and in which Figure 1 is a side elevational View of a conventional type ofvessel and indicating the application ofthe invention. 7

Specification of Letters Patent. atmlijed duly Application filed .1 uly 27, 1917.

Fig. 13 shows a modification ofwthewbaffle plate elements, together with their supports.

In the drawings, the numeral 10 represents thehull of the boat, the same being provided withtlie usual decks, smokestacksy masts, etc. a

Along each side of the vessel, at a point above the normal water line, are engaged b ackets 1 1, the same having outstanding flanged elements 15,-and containing elongated slots 16, in which the shank of the bolts 17 mayfreely operate. Pivotally s ecured by these bolts are links 18, whilerearward; of thebrackets 14-, are other brackets 20, having extending fianges21,co incident with which are similar flanges 22,1formed with a strip element 23, theflanged portion containing a pin 25, by means of which.

links 26 are pivotally engaged, similar links 28 being secured by p1ns29, affixed 1n the flanges 30 and31, thet'orlner being formed integrally with the strip 23,while the latter has an extending foot 32, secured tothe lower part of the vessel hull,"ascan best be seen in Fig. 41-, the pins being arranged one directly over another so as to be in the same aXial plane.

Plates 35 elvtending the full lengthof the vessel, have attached upon their inner surfaces atregular intervals strips36, the ends being turned inwardly forming flanges 37 and 38,respectively, at the top andbottom,

co-incident' with which are thefla'nges 39 and 10, formedwith the brackets 41 and 4E2, also secured to the plates 35, the'upper set of brackets containing pins 14., by means of whichtlie-links 18 and26are pivotallyengage'd, a similar pin 16 passing throughthe flanges 38 and ldco'nnectlng the lower link 28, both sets plane.

At tlieektreme front ofthe vessel are of: pins being in] the same initial secured brackets 5.0, in which i are hiiigedly engaged wlthln slots formed therein, links 51 pivoted by pins-52; similar brackets be outwardly the links 26 and 58 are turned upon their pivots, while the longer links 18 and 51 are not only turned upon their pivots but allowed to move forwardly within the;

' antelements 70 comprised of cork or other like'material, contained in nets 7 2, the same having compartments 73, therein so as to hold the buoyant material in place even shouldthe net become damaged.

'Aplurality of buoys 70 are used, the same being-connected near their front ends by connections 68 having flanges 69 in their ends and with which areengaged the succeeding buoys- A plurality of gratings 74: are extended between the buoys, which terminate at their lowerend'inrelatively heavy elements 75, so that the entire structure is held in a relatively vertical pendant position.

Engaged withthe hooks 80, set in the levers 63, are cables 81, passing over pulleys 82, to a winch or the like carried by the vessel and by means of which the buoyant structure atthe' rear of the vessel may be raised completely out of the water, as can be seen by the broken lines in Fig. 1, thereby offering =no impediment 1 to the free movement of the vessel, and it will be understood that the plates 35 are of ,a relatively thin cross-section and because of their position,

being parallel with the center line of the vesselat all times, that the plates will present substantially no opposition to the movement through the water, and particularly so when they are folded closely adjacent to thevessel sides.v

In'the views, Figs. 9 to 13 inclusive, is indicated a preferredfform of construction for-the baffle'plates, the same consisting of a wire'100, embedded in blocks of cork 101,

' the: blocks being made of rectangular crosssection and so molded that the embedded wire maybe colled about a relatively rigid bar 102,- a plurality of the coils being ar -"ranged in rowsas shown in Figs. 10 to 13,

inclusive, the several rows being held by Copieso! this patent may be obtained for bands 106 so as to form a light strong and buoyant structure of great elasticity and resilience.

In Fig. 18 single rows of the cork encircled elements 102 engaged by the bands 100, are connected together at uniform intervals by interengaged transverse rods 110, the rods and bands being soldered or otherwise rigidly connected together at their points of intersection.

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

1. In a device as described, in combination, with the side of a ship, a plate extending along one side thereof, a strip secured upon the inner face of said plate and formed at its opposite ends with right angular portions, angle strips also secured above and below the first strip to said plate and no viding arms disposed parallel to the right angularportions,similar strips secured upon the side of said ship and also providing the right angular portions and the arms, a bracket secured to the upper side of said ship so as to provide an additional arm, a lever pivoted between the arms and right angular portions at the lower ends of said ship and plate, and another lever similarly pivoted at the upper end of said ship side and said plate, a pin projecting through the upper arm of said plate, and a third lever slidably pivoted to the uppermost arm of the ship side and carrying at its outer end a depending sleeve engaging said pin.

2. In a device as described, in combination, with the stern of a ship, a pair of lever arms pivotally mounted thereon in projecting relation, a parallel series of cork buoyant elements, wire-mesh nets containing said buoyant elements, said nets having compartments for said elements, a pair of bearings for said lever arms, each bearing consisting of a pin formed at opposite ends with parallel sides secured between and against the sides of said nets, and between said buoyant elements, and a plurality of gratings extending between said buoyant elements and terminating at their lower ends in relatively heavy bodies.

In testimony whereof I have afiixed my signature.

MICHELE GIGANENKO.
