air supply strap having'a mouth piece for manual inflation, anda means for attaching" the containers to each other and upon; a per- 15 son. It is proposed to so construct the 0011- I tainers and the air suppl strap so as to be inflatable and maintain the inflation without actual valves. These parts should be so arranged to have an inherent valve action. The valve action referred to should be arranged independently for each of'the containers'so that'in the event of ruptureof one, all ofthem will notdeflate. The valve action is primarly accomplished by providingv a 25 small passage for air and composed offlexible material rubberized fornormally closing the passage. 8 1 A For further comprehension of the invention, and of the objects and advantages thereof, reference willbe had to the following description and accompanying drawings, and to the appended claims in which the varlous novel features of the invention aremoreparticularly set forth. r

The reference numeral 14 indicates generallya person having a swimmerslife saving belt'15. applied. This belt encircles the waist portion and consists of a plurality of air containers 16 with reduced inlets; 17 connected with an airsupply strap 18 having a mouth piece 19 for'manual inflation, a means 7 20 for attaching the containers to eachother,

another means 21 for attaching the contalners upon a'person.

"Each of the containers consists of apair of superimposed congruent sheets. of cloth 22 rubberized on their inner sides and hermeti- 'cally sealed along all edgesexcept at small tube constituting'the said mouth piece "19,

and'at portions along its length where the reduced portions 17 of the containers connect.

This arrangement provides an "air passage extending the full length of the air supply strap and connecting with the interior of the containers 16.]

The saidreduced inlet portions 17 of each o f'the containers consist ofthe sheetsof the container flat against each other andfare engaged between the material 22,0f the air supplystrap. In Fig. 7 the air passage between the reduced: inlet 17 and the sheets 23 is high:

other and open slightly only upon theiforcing 1y exaggerated. In reality they toucheach I of air'through these parts. Immediately adjusted. The means -21" for attadiingT the thereafter they touch each other again and form a valve action forvretaining the air 7 within the containers. v p

The said means 20 forattaching the containers'to each other consists of forming the adjacent edges of each of the containers with eye jopeningsi24 and 'then'connecting these open- This arrangementperings with a lace 25. mitsthe distancebetween thecontainersto be containers upon a wearer consist of upper. and

lower straps 26 on each of the containers'and" attached intermediate of their ends. This, permits the'ends of thestraps to-be free, and

v adjacentfends ofadjacent straps are formed with eye openings 27, and lace 28 is engaged between these openings for connecting the straps. Y W

a The vouter ends" of the upper and lo wer straps 26 of the first and last containers16 areattached upon vertical dowels 29. .These dowels are adjustably connected with the vertical edgesfof the :container by lace's30. A

' strap 31- with a buckle 32 is attached upon one of the dowels and the buckle is engageable zwith anothe'r strap-33 attached upon theother f the dowels which completes the means f or' 'attaching the belt upon a. person.

,In Fig. 4, thesection ofthe'top strap 26 discloses that thisstrap is made from fsheets of cloth :with rubber therebetweem Adjaf cent edges'of eachfof the containers are :reinforced with-strips 34 securedon their inner sides. This isclea'rly shown in Fig. which represents a section of adjacent containers in Fig. 2. The airpassage straplShas been de- A 'fined with a central air passage indicated in Fig. 12 byreference numeral:35. This air passage is highly exaggerted in the draw.- ingbrit-serves to illustrate its arrangement.

Because of the length of the'air passage strap, it has been foundnecessary to insert an intermediate passage tube ;36;for holding a portion of the passage open so that'it is not very diflicult to inflate the device; The passage tube 36 extends for a shortdistance'between two of thereduced inlets .17 of adjacent containers; lAfter the. device has been inflated,lthei air passage strap:18 is turned up- .wards on theinner side of the belt asillustratedin.

In this position. each of the bentreducedinlets 17 insuresjagainst' deiflation of the air'containersif a v i In'thermodified';form of the device illustrated in Fig. 11, an air supply strap 18. has

. been illustrated connecting with the central preferred construction. this beltis similar, and correspondingparts maybe recognized by correspondingfnumen ;als.:" The valve action'inthis'case is obtained whenthe beltis securedabout a wearer which portionsof-the containers 16 instead of with the edges as illustrated and described in the accomplishes body of a wearer. v; I

In other respects firmly forces the passage withinthe air supply strap closed. 1

In operation of the device, it may be inflated manually by blowing through the,

mouth piece 19. The air forces the passage momentarily open'and also forces the passages through the reduced inlets 17 open so ingtheclosing ofthe passage of air and the locking of the air within the containers,

Afterthecontainers have been fully inflated, the air supply strap is bent upwards against an air tight constructio'n'is obtained. "Partic ular attention is called to the rubber lining of that the air may enter :the containers: Immediately upon the ceasing! of blowing, these passagesclose and particularly the redu'ced inlets 17 tend to bend for furtherinsur the containers and the air passage strap which the air tight valve action dis cussed. 1 V
