This invention relates tomeans fonindicating the position of a sunken submarine and for supplying air to the interior of the submarine so that the usual salvage operations may be performed without danger or loss of life to the submarine creweven though a Week or more may to the surface.

.Noyv "having, particular reference to the drawings A; designates generally a conventionalrsubm'arinel In carrying ont'my invention the opposite sides ofthesubmarine are. constructed: with? compartments '5. each ofwhich is open at its outer side as: disclosed clearly in Figures 3,.and 4a. 1'

*Mounted ivvi 'hin. the open outer side of each compartment is a pair of vertically, arranged swinging doors 676; These doors reso mountedwith respect to thecomp'art v v ment-that-they-have to be opened inwardly of, the compartment as disclosedbythe ari rows, in Figure- 4. The. c adj acent vertical edges ofthese doors areformedwithflanges 6,,f 6"',.th e. edges of which are formed at op,- posite; sides to the center withnotchesi, the

are rotated for causing the rotation of the bolt 1111 for drawing the arms 88 as well as their extensions 99 toward the top and bottom walls of the compartment which will break the joint between the arms and the extension whereupon the doors will automatically open due to the pressure of the water when the submarine is 'in'submerged condition as disclosed in Figure 2.

Within each compartment is apair of barrel shaped buoys 16 and 17 arranged in side by .siderelation within the inner wall of the submarine as clearlyv disclosed in Figure 4. The pair of bouys in each compartment are connected to the opposite ends of a relatively great length of cable 18 which cable is trained over a horizontal bar 18 anchored within the compartment, and as soon asthe doors 6 have been opened the water rushing into the compartment will cause the floating'of the buoys whereupon they will be guided to the open side of the submarine by; the doors 66 eventually floating to the surface of the water as indicatedin Figure 2. The buoys 16 g' are for the purpose of identifying the location of the submerged ship while the other buoys air to'reach'the interior of the'sunken submarine. 1 By detaching one of the buoys from the end of the cable 18 a hoisting chain may beattached to the cable and thence by pulling upwardly on the end of the cable attached to the other buoy the chain may be "engaged around the bar 18 so as to enable the salvaging ship to raise the submarine;

V Each buoy 17 is constructed with a longi tudinal air pipe-19, the lower .endof which has communication with an air hose 20 that communicates at its opposite end with the interiorof-the submarine as disclosed in Figure 3; Liquid food may also'be conveyed to the submarine crew through this air hose.

The outer end of the air: pipe lg projects through the. top wall of the buoy: "and is threaded for the reception of a cap'23 which cap is of cylindrical formation and formed at its sides with air inletop enings24= so as to permit the'air to pass into the pipe. This buoy will riseso rapidly through the water that the small f'amountfof water passin through theopenings into the pipe19 and hose 2 will be negligible 1 V clearlydisclosed in Figures 6'an'd7 the sidewall of the buoy 17 extends above the top wall thereof so astofprevent thewaterfr'om- I flowing into the ope1'1 ings'24; Said side wall 7 of the buoy directly-above 'thetopfwall "is formed with'water outlet openings 25 so that the water cannot collectfin the'space above sa1d top wall."* 1

" The bottom wall of each buoy 17 is formed 7 that communicates at its opposite end to a suitable telephonic instrument within the in- 1 terior of the submarine so that conversation may be held between the submarinecrew and panying drawings, it will be apparent that I have provided ahighly novel, simple and extremely useful position indicating and air .7

supplying device for sunken submarines and herein I have shownand .described the in vention consisting of certain detail structural elements but nevertheless it will be understood that somechanges may be made therein'without' afiectingthe spirit. or'scope of the appended claims.

It is. obvious that my invention is susceptible to various changes and modificationsin construction without departing from the spirit ofthe invention or the scope of the appended claim, and I- accordingly claim all. such forms of the device to which I am entitled.

Having thusdescribed my invention, what I claim as new is:

In 'ameansfor supplying air to the interior of a sunken submarine, a buoy normal 1y attached to the submarine and adapted to float to the surface when released from the submerged vessel, said buoy comprising top and bottom walls, and an interconnecting side wall,the upper edge of the sidewall proj ecting above the top wall, the upper portion of the. sidewall directlyabove the top wall being formed with water outlet openings,.an air pipe extending through the top and bottom walls, the upper end providing an air in-} let and projecting above the water outlet. openings in the. side wall, a cylindrical cap secured at its lower end on the upper end of 1 the air pipe,-the top of the capbeingclosed,

the side of the cap above theupper end of the air pipe being formed with. airinlet openings, 7 and a hose affording communication between the lower end of the air pipeand the interior of the sunken; submarine. J V In testimony whereof I aflix my signature.
