Specification of Letters Patent. Patented Jan. 14, 1919.
Application filed May 27, 1918. Serial No. 236,705.
Improvements in and Relating to Life-Preservers, of which the following is a full, clear, concise, and exact description, such as will enable others skilled in the art to which our invention relates to make and use the same,-reference being made therein to the accompanying drawing, which forms a part of this specification.
Our invention relates to life preservers of the type or class having a. hollow collapsible and inflatable supporting member, to-
gether with means for supplying gas to the interior of said member to there y lnflate and expand the same and render it buoyant,
. because of the volume of water displaced by it; and particularly to life preservers of the type or kind above referred to and in which the operation of the inflating means, device,
or mechanism is dependent upon the action of the water in which the preserver floats; so that the inflation of the inflatable member will take place when the preserver reaches the water, and is brought about by the action of the water upon some element or device present in and forming a part thereof.
The object of our invention is to provide a life preserver of the general type above referred to and one in which the inflation of the inflatable member is entirely automatic, and requires no act whatever on the part of the wearer in order to insure the inflation of said member; so that should a person wearing a preserver made in accordance with our lnvention sufl'er ln ury, become bewildered,
or be otherwise incapacitated from acting during the confusion ordinarily incident to the sinking or to serious injury inflicted upon or sufiered by a vessel, then and in that event the inflatable member of the preserver will, upon the falling of the-person wearing A further object of our invention is to provide a life preserver of the type in question in which the means for accomplishing the inflation of the inflatable member is in the form of a single unitary device or structure, and is entirely independent of the specific form, shape, or other characteristics of the inflatable member; so that inflating mechanism of one standard form and construction may be used with inflatable members of various shapes and forms, and with inflatable members adapted to be secured to and worn in various positions upon the body of the user.
A further object of our invention is to provide a life preserver having the features above enumerated and one which will be simple in construction, reliable in its operation, and effective for the purpose for which it is designed, and which may be manufactured and assembled and made ready for use, at a minimum of expense.
lVith the above and other objects of invention in view, our invention consists in the improved life preserver illustrated in Figure 1 is a View showing our invention as applied to an ordinary form of life preserver, in the form of a belt designedto extend about the body of a user;
Fig. 2 is a view upon a considerably en-' larged J scale showing the gas generating mechanism by itself, a portion of the casing thereof being broken away to show features of internal construction;
Fig. 3 is a view showing a section upon a plane indicated by the line 33 of Fig. 2; and
Fig. 4: is a view similar to Fig. 3 but showing the parts in another phsition.
Referring now to the drawing, Fig. 1 illustrates a complete life preserver made in ac cordance with our invention, while Figs. 2, 3 and d illustrate the gas generating mechanism thereof by itself, and unconnected with the hollow inflatable member designed to be secured to a person; it being expressly un derstood that our invention includes gas generating mechanism pe'r 8'6, and apart. from an inflatable member, as well also as the combination of a gas generating device and an inflatable member; and that the gas generating mechanism as a unitary structure may be secured to any kind of a hollow 1nflatable member, and to inflatable members designed to be secured to or worn in varlous positions by and upon the person of the user of the device. p
In Fig. 1 the gas generating mechanism is shbwn as secured to and carried by a hollow inflatable member 3 in the form of a belt designed to extend about the'body of the wearer, and vthe ends of which are securedtogether in any way as by means of the fasteningmembers 4, 5; the gas generating device as a whole and indicated in this figure by the reference numeral 6, being shown upon a larger scale in Figs. 2, 3 and 4. Referring now to Figs. 2 to 4, the reference numeral 7 designates a portion of the wall of a hollow inflatable member, the same being provided with an opening Withinwhich the gas generating mechanism is secured; the said gas generating mechanism j having a closed casing within which the various elements thereof are contained; and
which casing is made up of an inner casing member 8, an outer annular casing member 9, and a cover 10 closing the central opening edges ofthe peripheries of the casing mem- V bers in order to secure a'tight joint between in the annular casing member; said casing members being secured together and in place 1n the opening in the wall 7 by screws 11 extending through holes in the ,casing members and into threaded openings provided in a ring 12 between which and a flange on the inner casing member the edge of the inflatable member is clamped, in the embodiment of our invention illustrated; a gasket 13 being interposed between the meeting the parts, as will be appreciated.
The cover 10 is provlded with a depend- 111g annular portion or flange lei: which is in threaded engagementwith an opening provided in the annular casing member 9, and
the inner end 15 of this depending portion forms a valve seat (referred to hereinafter and in various of the concludlng clalms as asecond valve seat), and a plurahty'of holesv 16 are rovided in said' cover through which water may flowj when the preserve'r comes into contact wlth the water; the holes forming a normally open water inlet passage through. which water'may flow into the interior of the casing of the f gas generating device, and which passage extends past and is surrounded by the valve; seat 15, as will be appreciated. Said cover 10 is also provided, with astrut member 17 which serves as a'guide for and as a part of locking mechanism associated with and adapted to hold a valve located Within the casing upon its seat, as will hereinafter appear.
The inner casing member 8 is so shaped as to provide a chamber 18 adapted to contain a substancewhich will generate a gas when water comes into contact therewith, such, for
example, as ca cium car-bidthe said chamber being located in line'and concentric with theopening into which the cover 10 fits, and the same being annular in form in the embodiment of our invention illustrated; and the inner of the concentric walls 19, 20 of the said chamber forms a gas outlet passage through which gas may flow from the interior of the casing into the hollow inflatable member to thereby dilate the same. The particular form and location of the chamber in question, as well as the form and locationv of the gas outlet passage are, however, of secondary importance, and may be varied 1 within the scope of the concluding claims mences, there will be a sufiicient supply of v water within the casing to carry on the generation of the gas and to secure the production of a quantity thereof sufficient to accomplish the proper inflation of the hollow inflatable member.
Located within the casing of the gas gen- .erating mechanism is a valve 23 which, in
effect, forms a cover or closure for the inlet to the carbid containing chamber 18, the periphery of said valve seating upon the valve seat 21 and thus preventing the entrance of water into said chamber until the valve shall have moved off its seat; and which valve also-serves to seal the contents of the said chamber and prevent access of air carrying moisture thereto which, if not prevented, would tend to cause a gradual generation of gas due to the slow decomposition of the carbid caused'by the presence of moisture in the air. This sealing of the contents of the chamber which contains the gas generating material is ,the more .per-
fectly accomplished in the form of our invention illustrated in which the gas outlet passage from the interior of the casing in fact leads from the carbid chamber, by pro: "viding a second valve 24, which is secured to and moves with the valve 23 and. seats upon the upper end of the inner annular wall- 20 which forms the gas outlet passage.
The valvedesignated as a whole by the reference numeral 23 is preferably made up I move it off its seat and which, in the em-v of spaced upper and lower plates 25, 26 between which a flexible soft rubber disk 27 is clamped, and the valve 24 which is also of soft rubber rests against the lower of said disks. The disks and the two valves are held together by a centrally located tubular sleeve or guide 28 extending through openings provided in said members and having a shoulder against which the upper disk abuts, and a washer 29 at its lower or inner end; said guide having a central passage into which the free end of thestrut member 17 extends whereby said valve is guided by the said-strut member when it moves from its seat, as will be understood. The valve 23 is acted upon by a spring which tends to bodiment of our invention illustrated, is located within the carbid chamber 18 and surrounds the inner annular wall 20 thereof, and to which spring the reference numeral 30 is applied. p
The valve 23 is held in place upon the seat 21, thus sealing the contents of the chamber 18, by means dependent upon and controlled by a soluble member located within the casing of the gas generator in the embodiment of our invention illustrated,
and which holding means when released by the action of Water upon the soluble member releases the valve and permits the spring 30 to move the same away from the seat 21 and into contact with the second seat 15,. to thereby arrest the flow of water into the casing and permit the water which has already entered thereinto to come into contact with the gas generating substance or material contained in the chamber 18; the preferred form of holding, locking, and releasing mechanism and the operation thereof to accomplish the results enumerated being V as follows: The upper of the valve disks 23 carries a movable locking member shown as in the form of a U-shaped spring 31 one end of whichis secured in an abutment 32 struck up from the material of the disk and bent down over the spring, as shown in Figs. 3 and 4;, and which spring extends about a guide 33 also struck up from the disk; the free end of said spring which forms a movable locking member lying in a recess 34: provided in the tubular guide 28, and the-said end being normally in line with the end of the strut 17. The said free end of the movable locking member is held in the normal locking position in which it is shown in Figs. 2 and 3 by a soluble member 35 carried by the disk 23 and held in place by an'abutment 36 thereupon. When, however, water entering the casing has dissolved the said soluble member, which, may be a block ofsugar or any other suitable soluble substance, or weakened it to such an extent that the force 0f.the spring 31 may crush it, then the locking member will move out of the recess 34 and away from in front of the end of the strut 17, and the spring 30 will move the valve 23 ofi its seat as hereinbefore explained; it being understood that the valve in question is normally closed on to the seat 21, and that the locking member or spring- 31 normally lies opposite the end of the strut 17 to thereby lock the valve in place upon its seat.
In view of the premises it will be appreciated that should a person wearing a life preserver equipped with or made in accordance with our invention fall, jump or be thrown into the water, perhaps in an in- .jured or unconscious condition, water will 23 from the locking actioh of the strut 17 and movable locking member normally lying opposite its free inner end, and'permits the spring 30. to move the said valve awayv from the valve seat 21 and into engagement with the second'valve seat 15, thus arresting the flow of water into the casing.
Before the upward'movement of the valve 23 occurs, ,however, a; considerable quantity of water will have entered the casing, or at least a quantity suflicient for the end to be accomplished, the interior of the casing being quite roomy and additional water re ceiving and holding capacity being provided for by the annular groove 22. When the said valve moves from its seat it uncovers the mass of calcium carbid or other gas generating material contained within the chamber 18, and the water present within the casing is thus permitted to come into contact with the gas generating material; whereupon a gas is produced which flows through the gas outlet passage formed by the wall 20 and into the interior of the hollow inflatable member, thus inflating and distending it in a manner which is entirely automatic, and without any attention on the part of the wearer or theperforming by him of any act or operation whatever upon the preserver or upon the mechanism thereof whereby the gas for infiatingthe same is generated or 'into the casing, prevents the flow of gas therefrom; and the. force with. which the valve. is pressed against this last mentioned hollow inflatable member; a casing carried by said member and having a normally open water inlet passage, a chamber adapted to contain a gas generating substance, and a "gas outlet passage through which gas may flow into said inflatable member; a valve seat extending about the inlet leading into said' chamber; a valve within said casing and adapted to seat upon said valve seat to thereby prevent the entrance of water into I said chamber; a spring acting upon said valve and tending to move it ofl its seat; means for holding said valve in place upon its seat; and locking means cooperating with said holding means and adapted to be held in its normal locking position by a soluble member located within said casing.
