Not only did this procedure require considerable time to perform but at least two men were required, one being the diver and the other operating from within the ship to apply the nuts to the bolts and to cinch them up. In cases where the leaks happened to be in the bilge plates or at points deep below the waterline, the diver had a very difficult task ands ometimes, was unable to dothey job at all. .L Q3; I ,i u f I have provided means whereby repairs of the above-described type may be very expeditiously-l, accomplished and wherein the work may, ifJl needs be, requires the services ofy only one Vman or two at the most. In Figures 5 `and 64 Ilhave:

shown the principal embodiment of "my inven'-"" tion which comprises what maybe aptly -termed '1 a bo'bber having a pair of cylindrical vplugs* ,I2 I and I3 which are secured lin the opposite ends i of a tubular rubber sac I4, bands I6 encircling the ends ofthe sac'bein'g 'crimped AcircumferentiallvI so as to'radially 'compress thesac about the plugs and thus provide 4a iluid-tightjoint therebetween.- Iheplug I3is provided with acoaxial tubular extension I1 threadedinto the outer end of whic'hi'sl a' tubular valve housing' I8 havingaN pair' of diam'etricallyvopposed ports I9 opening throughfthe'side walls thereof and `into the chamber 2`I The plug member I3, in the; tu'- bfular' extensionfllthereof, is providedwith a similar 'axial' chamber -22 andducts- 23 drilled longitudinally V'through the` plug' member I'establish communicatonjbetween the chamber 22 and 4thesac cavity ,24. rAc'heclt valve,` preferably of theinap type, is providedirrthe chamber 2| for the purpose of 1imitingv flow of fluid, specifically air, unidirect'ionall'y ,throughth'e ports I9 v,and thenceinto the sac cavity 24."`Indetail however, it comprises ga cup-shaped rubber {member 26 the valve' housing I8, the closed end4 28 fof the member' being centrally apertured to receivea screw 29 threadedinto housing and-serving to `ret'a'tin the rulrbervalvev in` place;v The' skirt fof the 4valve'mem-ber is extended sufficiently so as ,to complet-ely'overlie" and 'close the ports I9.` It

will be seen that'if `pressure exists :in the cham'- ber'` 2l which exceeds atmospheric'therubber valve will be jsubjectedto 'an internal'raldialfex- [pensive 1 force tending to bulge the1 Aportions `)of 'the valvev skirt in registry with the' ports VI 9 outwardlythrough the latter and thustlghtlyseal the, portsv and ,thel chamberi'ZI. Conversely; if

air, at rva pressure exceeding that' whi'chmay exist in the chamberf2I,is admittedto the ports I9 from the exteriorof the housing I8, the valve vskirt will' be readily ,dispiaeainwardly thereby opening the ports and permitting the air to ow cation, ,c through afpluralit'y'of drilled ,passages isa withy the cavity 241Tne peripherai'porton of the bottomof `the bore ,3l bordering 'the .coun- ,tenbore ,312 form a valve seat adaptedtoeng'age 36 adjustably engaged, by vmeans ofthe screw jsized 'to snuglyt into the chamber bore 21 of f 4 threads 4I in the end of the plug I2. A coil spring 42, interposed between the disk valve 36 and the plug 39, serves to forcibly maintain the disk valve on its seat. Vents 43, drilled through the wall of the plug I2, serve to establish communication of the chamber 44, defined by the bore 3|, with the atmosphere. Let us assu-me that a. pressure of 25 pounds per square inch is all that wcan safely beintroducedinto the cavity 24 to expand the sacIlI. The1 plug .539,5 is manipulated seas to compress the spring 4-2` and thus store Zin it sufficient force, in addition to the pressure off the atmosphere against the exposed area of fthe fdisk valvefearrier, to just 'balance the predeterminedl'pressure which will be imposed on ythefa-ce ofthe disk valve in the chamber 33. If

, air ,at-,apressure 0h25 pounds per square inch is admittedthrough the charging ports I9 into the cavity-24 the sac I4 ,will expand radially, as shown in Figure 6, to the point where the stretched member andthe force ofthe atmosphere on the exteri-orfthereof exertsa-counterpressure sufficient to balance the-internal pressure. Under these conditionsthe valve 36 will remain closed since no more pressure than the pre-determined amount may 'be admitted into the cavity 24fro-m the source. @.AI-IoweverlinK the event that air at a pressure in excess of 251pounds per square inch is admittedlthrough the Vcharging ports I9, the sac will expand toafpoint wherein its internal pressure slightly exceeds 25 pounds whereupon the valve 36 will vcrack open and allow the excess pressure, foraslbngas it may persist,.to escape from'the1cavity24 through the passa-ges 34 into the chamber 32 andthence through thelvalve port and vents 43 to the atmosphere l p i;

Conveniently'portable' meansiis provided'flfor storing fluidunder pressureV and for inflating the bobber when desired. Referring to Figures 3 and 4, a plier-type hand tool-is provided comprising a cylindrical body 4B having a` chamber 41 therein which may be charged with a volume of compressed'air fromk a 'pump or other source through 'a charging valve 43 carried by a plug 49 which is in-th'readed engagement with a boss 5I xed jaw 52 and a pivot lug 53,1 the latterbeing l into the chamberZ I and thence into the sac". I4f A Y,

Extending axially into the plug |`=2 isl a,bore, 3l having latthebottom thereoffa coextensive counterbore 32 ,forming fa' chamber 33 whichv is in communi- 'provided 'with a fixed pivot pin 54. A triggerl 56,

The remote endsv of the `arms 51 are connectedfintegrally with a jaw 59 which confronts and parallels the xed jaw 52.

Thus `any forcewhich tendsto compressthe sac axially will be resisted by the .tube |03 .as will.;v forces tending to flex the sac about its axis. However since lthetube andcollar 4are free to move toward the left -asviewedand shown in Figure 6 ther-normal, expansion of the, sac when vair ,pressureis. admittedthereto .will in no Way be interfered with. i l

In Figure2 I have shown a modified `form of device, although operating'onl the, general principles outlined above, `is intended toserveas a leak` ,Stopper incertain instancestwhere repair bolts cannot conveniently. i be y.used or wherein the outboardportion vof abroken rivet cann'ot be removed or.. driven from the hole. The plug member ||4 is secured in the end of the rubber sac; H6, as already described, by-.means ofa crimped,metallicfbandf||1 and a tube, ||8, anchoredattone end in a central aperture ||9 formed in the. plug member,` has a globularouter end ;|2| and is, provided V3with apertures- |22 through which communication maybe had from the .interior of the tube to the cavity |23 of the sac. `A valve housing |24, similarto the. housing I8, is provided being threaded onto a nipple-|26 formed on the plug |4 and is. fitted with charging ports |21 andseating surfaces 28 bordering the ports. Inthe chamber.|29. ofthe valve housing is a checkvalve |3| `identical with the valves previouslydescribed except .that a screw |32 having; an axial bore,|33 therethroughis pro-f vided for. securingthe valvein place@ .The passage |33 through the-mounting screw `opens into a chamber |34, Aconcentric .withthehousing, which is closed by a threaded lplug :|36 having a centralfaperture |31:.and.radial ly spaced ports |38. A valve stem |39', slidable` in Athe aperture |31, has-an rintegral valve, disk |4| overlying and ,closing theports |38 outsideof the-chamberLl34 and acoil spring |42, concentric with-the stem `|39 and interposed between the plug |36 and a washer |43 which is mounted yby a nut |44 on the ste`m,serves to hold vthe valve disk llllyfwith .adjustable pressure in position-closing the ports |38. 'Ihe stem |39 is eidzendedl bya shank|46 beyondthe valve-disk |4| and; is fitted with a head |41 whichprojects suiiicientlycbeyondthe outer end ofthe plug |36, toenablet a person to grip the heady |41 with his. vfinger. nails and thus lift the valve disk |4| from-.its-zseat. Acap |48 provided with vents |491is ,providedl for engaging Atheprojecting threaded end of the plug: |36 and isforthe-purpose of protecting the valve'mecha'- nism yagainstaccidental disturbance or damage. 'The tube-.H8 in the sac ||6 lends suicient rigidity tothe latterso that it may beworked, in ,deflated` condition into holes. or cracksthatare to be `closed afterwhich the sac' is inflated inthe manner abovev described, Thisdevicelis useful both, asfa Ibobberfand as ameans'forstopping hole leaks when alarge'group of .theflatterexist and it-is desiredto' reduce theylarge volumeof water owinginto the vessel `while the; more permanent repair effected `.by thebolts 96 may be carried on in ,successiveof the;holes.`
