Application filed March 28, 1917.
- To all whom it may concern:
Be'it known thatl, FEELING C. Fos'rnn, a citizen of the United States residingat Chicago, inthe countyof Cook andState of Illinois, have invented a certain new and 1 useful'lmprovementin Self-Ini iating Floats,
ot collapsible floating bag or balloon which bit in all :the: figures.
of which the following is a specification.
My invention relates toimprovementsin life savers and the like, and has: forlone object to provide anew and improved form will automatically. fill with gaslunder, sulficientpressure to distend is as soon as it becomes immersed in the water. Other objects of myinvention will appear from time to time in the specification.
My invention is illustrated more or less diagrammatically drawings, wherein Flgure l 's a side elevation showing parts a in section;
Fig. 2 is a section through a partof the automatic inflating device;
along the line 33 of Fig. 1;
Fig. 4 is a section along the line 4% of j v I 5 [is a sectional view of one end of a modifiedformof water tube.
Like parts are indicated by like letters A is acanvas cover; Itcontains a rubber air-tight vbag A adapted to be inserted 1nto the canvas cover thnoughthe slit A closed by lacing This canvas cover is proneckAiof the bag. t
1B is a. rigid metallic chamber. B is a metallic inflating tube contained within the 7 parts A ,;A It has an enlarged head 13*,
which head is located within the bag adjacent therneck. B is a .metallic ring surrounding the member B integral wlth a sllt sleeve Btwhich slit sleeve is held closed by wrapping B The member 13 is screwed tight into the member 13 clamping the.
parts together to hold the inflating device on the bag as shown. C is a snap lioolc fastened to the band B wherebygany load,
may be attached to the fioat inzanyyway which may beappropriate. a
. The cylinderor tube 13 1s open at 5 both ends and is adapted to containa supply of material which forms gas when in contact withwater such as car-bid so that acetylene s e. s ay b f e ime ;T e e d Ofth r Specification of Letters Patent.

through theperl'orations wettingthe blotting paper and. elothmand thusnpassing through to wet the carbid. As. soonas the .carbid becomes Wet gas will be generated and this will compress the blotting paper andcloth into the openings and more or less etl'ectually prevent the escape of the gas.
;It will also,however, prevent the ingress of any water and so separate. means must be provided to continue the moistening of the carbid to form the gas. These means take the form of a tube E which contains water. This tube E is open at both ends. It is providedat each end with. a plug E This plug is slotted as 'atE so that the water maypass out. It will be noted that the plug is provided adjacent its outer periphery with. an annular groove E andthe ends of the tube are upset as E. E is aavaxed or paratlin plug which is poured into the space betweenthe upset end of the tube and the plug and which. penetrates more or less into the slots and into the .annular ring so as. to make a suflieiently watertight joint thus closing the water up inside the tube. The small amount of water which enters the main receptacle from either end when it is first immersed which inaugurates the formation of the gas will cause the genera tion ofsutfieient heat inside the chamber to meltthe wax or parafiin plug and to permit the water to run outifromthe tube into the chamber. water to complete the gasification and this gas which is formed in this brass or metallic chamber will rush out into thebag and inflate it. This action takesplace almost immediately since there is an excess of water present and the balloonwill be inflated almost as soon asitreaches the water so thatit will instantly commence to operate as a life saver or float or support for any objects which may be attached thereto.
It will be evident that while I have shown in my drawings an operative device, still many changes might be made both in size, shape andarrangement of parts without departing materially from the spiritof my invention and I wisln therefore thatniydrawingsbe regarded as in a sense diagrammatic.
This will furnish sufficient hang onto them.
The use and operation of my invention are as follows p I These devlces are maintained on the boat folded up in position foruse readyloaded;
loads in the water, it beingnecessary to, provide means only for-fastening the hooks so that such loads could be supported.
In 'themodifled form it will be noted that the metallic plug in the water cham her is omitted. The end of the water ehamberlisgmerely upset and crimped and the wax lplug is poured in'there. When this melts', of course, the water will beable to rush out even'more freely than if the metallic fillingwas used.
Obviously the apparatus which I have de-' scribed carries out'a peculiar and novel *process, wherein the fuel is first treated or 'vided owing to the increase of temperature,
actedupon by water and then by the pressure-of the fuel the supply of water from outside is out off and'an additional supply' of fluid from elsewhere is subsequently pro- I claim: 1.
