AU rescue bell to the surface of the water for discharge of the passenger or passengers in it ;y to provide novel means for controlling and operating such an apparatus; and to provide the novel combination and arrangement of t parts ldisclosed in vthe accompanying drawinOfs.

rFVe yattain these and lother objects of our invention by the apparatus disclosed in the accompanying drawings, in whiclny Figure 1 is a side elevation of the invention assit is being lowered for attachment to the safety hatch on the deck of a sunken sub Y marine;

Fig.V 2 is a view on a plane at right angles to the plane in which Fig. 1 is taken on the section line 2 2 through the submarine the submarine being rolled on her port side and the rescue bell being attached to the starboard hatch;

Fig. 7 is a detail Vertical section through the lower portion of the rescue bell and the adjacent portion of the wall of the subma Like characters of reference designate likeparts in each of the several views.

Referring to the accompanying drawings,

we provide a suitably shaped rescue bell 1,v

which if necessary may be used to supplenient the main operating cable 10 for raising and lowering the rescue bell. We provide' suitable' braces 4 extending from the top of the post 2 to the upper portion of the rescue bell 1, as shown in Fig. 3.

Slidably mounted on the rescue bell are a plurality of horizontal arms 5 slidably mountedon the post 2 between the top 6 of the rescue bell and the annular lange 7 on` post 2. lVe provide rods or cables 8 extending from the horizontal arms 5 to a ring 9 to which an operating rope or cable 1() is attached, and which may also be used for raising and lowering the bell. Secured to the ends of the horizontal arms 5 are rods 11 which are pivotally connected to the upper supporting arms and are slidably mounted in spaced apertured braces 12 and pivotally connected at their-.lower ends to clamps 13, which in turn are pivotally mounted in a suitable manner7 as by brackets 14, on the lower end of the rescue bell.

XVe provide suitable springs 15 arranged to exert resilient pressure down on clamps 13. Positioned near the lower end of the rescue bell is an annular platform or floor 16, as shown in Figs. 5 and 7, threaded as at 17 to releasably engage the circular screw threaded door 1S. le also provide a plurality of clamps o1 releasably engaging the door 18 to give increased protection against deep water pressure. lVe provide a suitable handle 19 for operating door 18, and may provide a suitable gasket 2O to make a watertight closure.

le provide suitable and preferably approximately S15-shaped locks or bolts 21, which may be provided with collars 22 resting on the floor 16. These locks are operable from within the rescue bell and are adapted to engage the annular-ly flanged anchoring ring y23 which is integral with or aiiixed to the door 25. Spaced from the anchoring ring 28 is a second anchoring ring 26 having an outturned annular flange 27 adapted to be engaged by the hook ends of clamp 13.

We provide a suitable gasket or resilient `ring 28 resting onthe annular. flange 27 of `the anchoring ring26. The ring 26 which is integral with or affixed tothe hull of the submarine is spaced from the anchoring ring 23 sulliciently to just receive the lower end 'of therescue bell in the manner illustrated in Fig. 7 of the drawings. le also prefer to provide a suitable door 29 to permit convenient accesss'tov theinterior@ ofthe bell i through the side Wall thereof and we may' provide one ormoresuitable ports' or wins'- dows 30 in the wall ofthe rescue bell, as

shown in Fig. 3. l/Ve' provide suitable iieirible air. pipe or conduit 32 through whichair. may bepumpedto the interiorof the bell yiivhe'n the'bell'is long submerged'. l

The mode ofoperation of .the invention is illustrated in Figs. land 2r of the drawings.

The rescue bell is lowered by the yoperating ropes-r `cable lO'whi'chis Vattached to ring 9 to y.which in turn the 'rods 'or .cables 8 are secured, vthese Vrods or cables in turn being secured tothe horizontal arm V 5 slidablyy mounted on the post 2, yas shown in Fig. 3,

kand to Vthe' ends of which armsv the roidskll .are pivotally attached,- ythe rods 1l in turn being attached, at their lower end to the pivted :clamps which yare yheld in a raised :position so that when the rescue bell comes in contact with any one ofthe three safety ports A, B,y.or C, the ybottom portion of the bell mayfseat .over this port in the manner shown in Fig. 2, the operating rope or cable being lowered to allow the spring controlled clamps .to engageiunder. the annular flange 27 of theV anchoring ring 26 .whichA is integral withor affixed tothe lhu'll of the submarine. 'lheIS-shaped blocksl or bolts-22 are swung into engagement with the inner anchoring ring 23, 'as shownk inFig. 7. The' screw threaded ldoor 18 is removed from its' seat and the door 3l ofv port 24 is opened, thus aifordingaccess of the imprisoned passengers of the sunkengsubmarine to the rescue-bell.

' The door Slmayv then beclosed, the door -18 replacechthe locks or bolts 21.1eleased and the rescue bell elevated by means of the lmain icable 3 which is yattached securelyto the post 2 at the top 'of the rescue bell.

Itis our belief that three or--four'resting platforms 'A,YBY and C can be placed in such positions on the submarine so that in no matter what position the submarinemight lieA a contact could reasonably'be made especially with the assistance of divers Vto assist in directingoperations. t is within-the-contemplation of our invention that means for directing contact'of ythe rescue bell with one of the resting'platforms may be accomplished by a suitable means not disclosed VinV this speciiication, without theassistance .of divers.

What we claim is: 1. ln an apparatus of the class described adapted for use with a submarine having atlattaching the cable to the upper end of the rescue bell, spring actuated clamps mounted on the lower end of the rescue bell and adapted to engage suitable attachment means on the submarine, and means operativelyconnected withv said clamps for controlling them from a point` above the surface of the water.

2.,V A :rescuef bell for useV on s submarines, comprising a cylindrical structure having a posta-Ontheanpper .end thereof to which a cable may be attached, pivoted spring actuated Aclampsmounte'dffon the lower end thereof'and adapted to engage. .an attachment member on the hullof the submarine, rods attached to said clamps, and means operatively'connecting saidrods with a cable adapted to'be'l operated from a pointabove the surface of the/water to control the action'of the clamps, 'and a water-tight doorin thelower portion 'ofthe rescue'gbell adapted vto be `opened from within theres'cue belly after it has been attached to the'. hull ofthev submarine over a port thereof.. 'A ,f

'3. In' an apparatus cftheclass described, the'rcombination with a 'submarine ofmeans for securing a rescue bell` tothe Vhull of same over a port of the submarine, saidl means comprlsmg anV inwardly Vturned L-shaped ring' encirclingzthe port and havingan annular flange, an outwardly turned L-shaped ring encircling the iirst ring and spaced from it a A'carried by the rescue bell.

Y 4. In an apparatus of the classdescribed, thev combination withl a submarine-of means for securing a rescue bell to the Vhull-fof same over a port of the submarine, said means comprising an inwardly turned "L-shaped' ring ,encircling the port' andl having an annular flange, an outwardly turned L-shapedring encircling the iirst vring and spaced from it a'suliicient distance to snugly. receive the lower end of the rescue'bell therebetween, each of said elementsbeing` adapted to be engaged by fastening means carriedV by the resl cue bell. Y l

5. In a rescue device for use on sunken submarines comprising la rescue bell, means for lowering the rescue'bell, reversely faced L- shaped rings spaced apart to receive the lower end of the rescue bell, said rings being affixed to or integral with the hull Aof the submarine and encircling ports thereof, and means carried by the rescue bell and operable 'from a point above the water for clamping the rescue bell to the outer ring, and means .operl able from within the rescue bell for attachingit to the inner ring, and an airtight door the bottom portion of the rescue bell.
