Application filed. February 12, 1917. Serial No. 148,287.

between the inner and the outer hull of the vessel for closing an opening in the inner hull, caused by a collision, thereby arresting a flow of water into the hull.

A further object of the invention is to provide a plurality of shiftable elements capable of being interposed between the outer and inner hull of aship for the purpose of reinforcing said innerhull to prevent damage thereto by collision.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically de scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes,variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout'the several views Figure 1 is a perspective view of a portion of the inner and outer hull of a vessel showing the adaptation of a-leak stopper associated with the innerhull.

Fig. 2 is a front elevation of a portion of a leak stopper.

Fig. 3 is an end view of a portion of said leak stopper with the coupling between the rolls removed.

Fig. 4 is an end view of a portion of said leak stopper with the coupling means between the rolls in position.

Figs. 5 and 6 are diagrammatical views illustrating the manner of shifting theleak stoppers.

Referring to the drawings in detail 1 denotes the outer and 2 the inner hull of a vessel and interposed therebetween are spaced bracing elements 3 in the form of T-irons. The elements 3 are secured to the inner face of the outer hull l and the outer face of the inner hull 2, by securing devices as at 4, 5.

The brace members 3 conform in contour to the shape of the hull in vertical section and each lateral flange of each brace member, at the inner end of saidbrace member, is formed with a lengthwise groove 6, extending from end to end ofthe brace member and capable of being shifted in a pair of opposed grooves 6 is a leak stopper constituting a combined reinforcing and sealing element for the inner hull 2.

A leak stopper is arranged between each pair of brace members 3 and when not in, such position they are arranged in guide grooves, not shown, formed in the bottom of the deck. The stoppers are not, when in operative position, of a height equal to the height of the hull, but are about one-half to two-thirds of the height of the hull.

The stoppers are to be arranged, when in an operative position, at each Side of the hull and when not in operative position stored in the guide groove of thefloor of the deck; the stoppers employed on one side of the vessel are arranged below the stoppers employed on the other side of the vessel. Each' of the stoppers has connected to its upper end a pair of elevating cables 7, which are adapted to wind upon the longitudinalshaft arranged in the guide groove in the deck referred to. lVhen the shaft 8 is operated in one direction all of the stoppers are elevated and housed in the recess in the floor of the deck. A shaft 8 is employed in connection with one side of the hull and a shaft 8 employedfor the stoppers in connection with the other side of the hull.

Each of the stoppers has its lower end for lowering the stoppers and said cables 9,

of the elements employed for both sides of the ship, wind on a single shaft 10 which is arranged at the keel.

Each of the stoppers consists of a plurality of rolls 11 and a plurality of filler members 12. The rolls 11 are alternately disposed with respect to the filler members 12 and each of the latter has curved seats 13, 14, against which seat a pair of rolls 11.

Each of the rolls 11, at each end has a pintle 15, provided with a reduced end 16. The enlarged portions of the pintle 15 travel against the side walls of the groove ("3. Each lit] llll'l of the tiller members has its end provided with a shaft 17 of the same diameter as the they will act as a reinforcing means and furthermore if an opening has been formed in the inner hull 2- by a collision, then by lowering the elements they will act as a sealing means and interrupt the passage of water into the hull.

7 hat I claim is 1. An attachment for marine vessels comprising the combination of members interposed between the inner and outer hulls of the vessel, each of said members in the form v of I-beam and each having the flange at the inner end thereof grooved, of a combined reinforcing and sealing member capable of being shifted against the outer face of the inner hull and extending into a pair of opposed grooves.

2. An attachment for marine vessels comprising the combination of members interposed between themner and outer hulls of the vessel, each of said members in the form of Ibeam and each having the flange at the inner end thereof grooved, of a combined reinforcing and sealing member capableof beingshifted against the outer face of the inner hull and extendlng into a pair of op- JOSBCl grooves, said element consistin of al h i i b ternately disposed rolls and filling members, means; for coupling sald fillermembers and rolls together, said coupling means sliding the opposed grooves, means for elevating and lowering saidelement.

3. An attachment for marine vessels comprlsing a combinatlon with an mner and outer hull and spaced bracing members between sa d hulls, the inner ends of said bracing members provided with opposed grooves, of a combined reinforcing and sealing member capable of shifting in said grooves, to a position at the front. of the inner hull, and means for elevating and lowering saidselemeat.

Copies bf this, patent may be obtained for i it An attachment for marine vessels comprising a combination with an inner and outer hull and-spacedbracing members between said hulls,-the inner ends of said bracing members provided with opposed grooves, of a combined reinforcing and sealing member capable of shifting in said grooves to a position at the front of the inner hull-,and means for elevating and lowering said element, said element consisting of alternately disposed rolls and filling members coupled together at their ends. I

5. An attachment for marine vessels comprising a combined reinforcing and sealing element adapted to be positioned between the outer and the. inner hulls of the vessel, said element consisting of alternately disposed rolls and filler members, said filler members having seats against which bearsaidrolls, and means connected to the GDClS'Of said rolls a and filling members 7 for connecting them to gether.

6. An attachment for marine vessels comprising a combinedreinforcing and sealing member for the hull of a vessel, said element consisting of alternately disposed rolls and filler members coupled together at their ends.

7,. An attachment for marine vessels comprising the combination with pairs of op posed grooves arranged within the hull, of a combined reinforcing and sealin element slidably mounted in each pair of opposed grooves, means connected with one end of said element for elevating itfromwithin the grooves, and meansconnected ,to the, lower end of the element for lowering it to a position within-the grooves, each of said elements consisting of alternately disposed rolls and filler members coupled together at their ends. Y

In testimony whereof I affix my signature in the presence of two witnesses.
