`This invention relates generally to' fire extinguishers and .has more particular reference to a novelmanual @operable firey eX- tinguisher. y 5 o f 5 y The invention has for an object the provision of 'a device of the class mentioned, which isof simpledurable construction, desirable inuse and efficient in action, and which. can be `manufacturedand sold at a l0 reasonable cost.;y
The inventionproposes the use of a bottle provided with a stopper thru which a metallic tube passes. A valve is arranged on the top of this tube and connects with a nozzle 1'5 and a head for depressing the tube. Said head is arranged on the top of the valve body. The lower end of the tube is provided with a vial breaking foot normally resting against y l a vial'lled'with citric acid. The tube may '20 be manually depressed for causing the breaking of the vial and *the kcitric acid within which coacts withy l a solution Vof sodium bicarbonate contained inthe bottle so as to o raise a pressure within the bottle and cause 25 a discharge of its contents.
` 30 the tube is in a depressed condition. This arrangement reduces the frictional resistances between the stopper andthe tube permitting easyk depression of the tube. A means may be provided for holding the tube inits "depressed conditionfor insuring a gas tight joint between'the stopper and the tube when the pressure within the bottle rises due to they' chemical reaction.
. o kThe rpresent application shows a further Y development of the invention disclosed in my pending application, filed August 24, 1928,
Serial No. 301,868. o
For further comprehension of the inven- 45 tion, and ofthe objects and advantages thereof, reference will be hadY to the following description and accompanying drawings, and to the appended Vclaims inV whichfthe-.variousy novel features of the invention are more par- 50' ticularlyset forth.
Fig.v 5 is anenlarged viewjof a portionof y y Fig. 2. Y.
The reference numeral 101' indicates generally a bottle of any design or constructionA preferably `made of'metal and providedfwith a neclrll having threadslQ. Acapil?) thread# edlyfengages upon the threadslfor closing p the top ofthe bottle. In'addition, alst'o'pper lat isrengaged withinthe'wneck'Q th bottle. A metallicv tube 15 passes vthruv an aperture 16 y formed in thecap 12 and thruan aperture 11:7,
formedfin the stopper. 'L1A Ycoll'arfris fixed `uponY the tube 15'beneaththe,stopper-14Tfor preventing excessive npwardmotion of "the tuae.; o The 'tube 1,5 isof L-shape and thebottoni portion 4IQVthereofis provided with a. lufy ralityj'of slots 20V for provili-nglfa'passage from the' interior .of thebottlethruthetube. f Y Y A vialzbreaking foot "21 is'attac/lied upon Ythe tube 'l5 and engagesagainst vial QQfilled with citric acid` 23.5' The vialY breaking Afoot 2l is: composed 'of two sections 4secured:to-`y ,f ggether.v v
The fop 0ftheiube :15 'is farmaci-mini@ within" this body, A jst'em26"c onne cts .on thevalvejbody and isprovided with a yhead 27; The lower'portion ofthe Villye body 24 of the-capl 'forjjlimitingzt'he downward motion ofthe tube ll5.` A nozzle 29 connects Y with the 'valvel so that in'o'pe'n condition of thevalve a passagel exists .betweenthc nozzle and the tube '151" o v Y llie'stopper14y has a tapered aperture portion'lF.' The tubeV 1'5 is provided with a pered portion j 17 i of the. stopper for -providpressed condition;V 'Thisf arrangement .re-`
Vhas a shoulder 28which`coacts with the top duces the frictional area between the stopper and the tube so that a much smaller force is necessary to depress the tube than if the contacting area between the stopper and the tube were greater.
A pin 30 projects from the shoulder 28 and is aligned with an aperture 3l formed in the cap 13 and another aperture 32 formed in the stopper 14. A stationary arm 33 is embedded Within the stopper and is connected with a pivotal link 34 having a pivotal locking pin 35 on its free end. This locking pin 35 extends into a transverse aperture 36 com` municating with the opening in the stopper 14. A string 37 connects ywith the pivotal joint between the locking pin 35 and the link 34 so that upon pulling the stringthe locking pin 35 may be moved into an inoperative position as shown in the drawing.
The tube 15 is provide-d with a recess 38 arranged yfor receiving the locking pin 35 when the ltube is in its depressed condition. Upon depression of the itube rlthe pin 30 enters the apertures 31 and n 32 `and acts against the locking pin 35 for moving the locking in'inwards into the recess 38 and thus hol ing the tube 15 in its depressed con dition. The tube cannot be raised until the vString y37 is drawn yupon for` retracting the locking ypin from its locking position.
In operation of the device the vial 22 is broken by manually striking the head 27 for depressing the tube. vUpon a breaking of the vial 22 citric acid within the vial is free andk chemically reacts with a solution of sodium bicarbonate 39 held Within the bottle 10. Gases are then released which raises the pressure yWithin the bottle and causes its contents to ass thru the slots 20 and thru the tube 15 an finally out of the nozzle 29. Thisdischarge may be directed againsta ame of a fire for extinguishing it. The nozzle 29 mayy be turned for operating the valve 25 and cutt-in off the dischargeif this is desired.
ile I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications comingwithin the scope of the invention as defined in the appended claims'.y
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is 1. In a fire extinguisher, av stopper :for closin a bottle with a solution of bicarbonate of so a and formed with an aperture, a tube slidably engaging in the kaperture for break? ing when depressed a vial holding citric acid within the bottle and for directing the disf charge from the bottle, a pin connected with the tube and extending within an opening in the stopper upon depression of the tube, pivotall connected links mounted in the opening 1n the stopper and extendible by said pin for engaging in a recess in the tube and holding the latter element depressed, and a string connected with the links and extending from the stopper for manual drawing to disengage the links from the tube.
2. In a fire extinguisher, a stopper for closing a bottle with a solution of bicarbonate of soda and formed with an aperture, a tube slidably engaging in the aperture for breaking when depressed a vial holding citric acid within the bottle and for directing the discharge from the bottle, a pin connected with the tube and extending within an opening in the stopper upon depression of the tube, pivotally connected links mounted in the opening in the stopper and extendible by saidpin for engaging in a recess in the tube and holding the latter element depressed. and manual operable means for disengaging the links from the tube.
In testimony whereof I have affixed my signature.
