(Cl. 169-31) be sold as a unit for recharging purposes, which is , The present invention relates to ?re extinguish ing apparatus of the type employing a ?re ex tinguishing liquid propelled by a medium stored easily replaced and which is in general fool-proof, it is necessary that a‘ holder which will receive under pressure in a cartridge or other container a cartridge easily and yet hold it securely, be 5 and embodies speci?cally means for holding or . provided. with the holder of the present inven- 5 suspending the cartridge in the ?re extinguishing ' tion, other types of extinguishers such as soda apparatus. ' , More speci?cally, the present invention ‘relates to a ?re extinguisher comprising a container for a 10 ?re extinguishing liquid, a cartridge containing gas under pressure, and a holder for the cartridge, the holder supporting the catridge within the con tainer of ?re extinguishing liquid in such a man her that the medium in the cartridge may be 15 easily released. ' It is the usual practice ‘to charge the cartridge with a medium under pressure, such as carbon dioxide, the pressure medium being seal'edin the container by means which must be punctured in uid extinguishers. '» I a The invention will now be described in detail 10 with reference to the, accompanying drawings, wherein: Figure 1 is a central longitudinal view of an ‘extinguisher embodying the invention. , b Figure 2 is a longitudinal view of a holder ac- l5 cording to the present invention. - Figure 3 is a top view of a holder or cage in accordance with the present invention. In Figure 1 of the drawings there is repre sented at I a standard shell or container for 20 20 order to release the gas under pressure. A cartridge, sealing means and seal puncturing device, or preferred embodiments thereof, such as are shown and described in my United States Let— ters Patent No. 1,919,149, granted July 18, 1933, 25 may be employed. The dii’?culty has heretofore been encountered that means for holding the cartridge have been complex and di?lcult to employ. The present in vention therefore broadly contemplates the pro 30 vision of means for placing a cartridge in the con tainer to form a compact unit that may be easily inserted or removed from the ?re extinguishing liquid container. and‘acid ?reextinguishers, may easily be con verted into stored pressure medium propelled liq ‘ holding a liquid fire extinguisher medium, such as ‘water, calcium chloride solution, or other suit able ?re extinguishing medium, which is ?lled into the container up to the level of the ?lling indicator 2. The shell is provided with a handle 25 3 for carrying the extinguisher in an erect posi tion, another handle 4 for carrying the extinguisher in an inverted position, a strainer 5, an ouiet elbow i, and a standard hose 1 coupled to the outlet el bow and having a discharge nozzle 8. A holder or 80 cage comprising an upper ?ange 9, a base plate Ill and suspension "rods II and I2 is supported upon a shoulder It in the neck of the shell and holder which is supported on the neck of the con in turn supports a cartridge ll containing a me dium under pressure, such as liquid carbon diox- 35 tainer of ?re extinguishing liquid and within said ide, for propelling the liquid fire extinguishing container. medium from the shell. The cartridge 14 is pro vided with a coupling I5 containing means for More speci?cally the invention contemplates a . _ A desirable advantage of the'present invention is that no tools are necessary in order to either 40 insert the cartridge in or- remove it from the holder. - - _ An additional advantage of the present inven tion is that the cartridge can not be removed from nor can it fall out of the holder once it has been 45 placed in the extinguisher container and the-cap has been securely fastened to the shell. A further desirable advantage, is that the holder is so designed that it'may be employed in punctur ing the sealing means of the pressure medium 50 cartridge. In extinguishers of the type here contemplated employing a stored pressure medium‘v cartridge, which is certain in operation and capable of wide spread adaptation' to use with ?re extinguishing I‘ apparatus of various manufacturers, which can effecting release of the pressure medium from the cartridge, for example, such as is more fully 40 described in my United-States Letters Patent No. 1,919,149, said releasing means becoming opera tive upon inversion and jarring of the shell, vwhereby to cause forcible engagement of the releasing means with a projection I6 formed on 745 the top ?ange 9. .A cap I‘! is threaded to the neck of the shell with an intervening gasket l8, which not only effects a leakage-tight joint with the O shell, but secures the flange 9 of the cage against movement. The cap I1 is otherwise standard, 50 being provided with a rim handle I8 for carrying the extinguisher in an upright position and for ef fecting rotation of the cap. The holder which will now be dwcribed in fur the: detail in connection with Figures 2 and 3, 55 9,069,700 comprises three suspension rods II, which are securely fastened at one end to the upper ?ange shell with liquid ?re extinguishing medium up to the level of the ?lling indicator 2, and replac tandatthe opposlteendtothebaseplate ll. ing the cap I]. tween any two of them on the same edge of the From‘the foregoing description it will be seen that I have made new and useful improvements in cages for holding or suspending stored pres 'lheserodsaresospacedthatthedistancebe baseisalwayslessthanthediameterofthecar tridge it. This distance is chosen to prevent the cartridge from passing between them and to . thereby retain it in the holder. A fourth suspen 10 sion rod I I is provided, which slides in a hole 10 20 in the ?ange I. The rod i! has an enlarged head II at the end situated above the ?ange l, the head being of a greater diameter than'the hole it of the ?ange s, so that the head cannot pass 15 through the hole in the ?ange. The opposite end of the rod is provided with a shank 22 of a smaller diameter than the rod. the shank being of such a size that it will readily slide into a hole 23 in the base II and permit the shoulder ll to Of course, in practice. the rod I! might be somade that it will rest on the head 2|, or on the shoulder it and the head I! at the same time. when the cage is being assem bled, the shank II is ?rst pushed through the 20 rest on the base it. 25 hole It in the upper ?ange I. A means of .nre venting the rod it from slipping out of the ?ange I after assembly, such as a cotter pin fl, is also provided. The rods II and II- are so propor tioned that when a cartridge has been inserted 30 in the holder and is resting on the base II, as shown in Figure l, the projection II is spaced a desired distance from the releasing means in the E i2 § 5 % insaid?ange,apluralityofrodsrisidlytastmed at oneendtosaidilangaabaserigidlyfastened at the opposite end of said associated with both said ?ange. and said base. said movable rod having a on said ?ange to hold the own weight when the hold is sition, ‘a stop on said movable rod to withdrawal of the rod from the ?ange. laid stop being sopositioned thattherorirnaybev topermit thecartridgetobeinsertedinandm 30 coupling II. It will be readily apparent that when it is de 35 sired to either insert or remove a cartridge, it is only necessary to raise the rod l2 and place the cartridge on the base It, as illustrated in Figure 2. The rod II is then dropped in posi tion through the hole I! in the base II and the 4.0 cartridge is then prevented from falling out of the holder by the suspension rods. When the cage and cartridge have been placed gas a ?lling opening at one end thereof, a removable cap for said opening, a cartridge containing av pressure medium for expelling "the ?re extin guishing medium irom said a holder in the extinguisher and the cap I‘! has been se curely tightened to the shell I, the rod I! can 45 not fall out upon inversion of the extinguisher. since the clearance space between the ?ange I and the cap I1 is not so great as to permit the shank I! of the pin II to come out of the hole 23 in the base II. In Figure 3 is shown a view of the top ?ange I, wherein is illustrated ?nger holes 2', which fa cilitate the removal of the cage from the liquid container. The projection it, which is securely fastened ; to the ?ange I, serves the purpose of releasing the pressure medium from the cartridge when the extinguisher. normally in an erect position as shown in Figure 1, is inverted, causing the cartridge to fall. The cartridge and pin are so spaced that the projection It enters into the coupling ii and operates the releasing means, which permits the escape of the stored pressure medium. In view of the present invention the act of re charging an extinguisher is exceedingly simple, comprising removing the cap I! from the shell I. removing the holder and cartridge i4, substi tuting a new cartridge in the holder,v ?lling the rods fastened at one end to said ?ange. a fastenedtotheopposlteendofsaid a able rod passing through ‘both said said base. said movable rod having a head adapt edtorestonsaid?angeplateto in position by its own weight when the holder in its normal podtion, a stop onsaid movable i . to prevent withdrawal of therod from the ?ange, said stop being so positioned that therod may bemovedtopermitthecarttldletobeilssrted in and removedfrom theholder, and a m tion on said ?ange adapted to forcibly engage said cartridge upon movement at the cartridge by‘ the force of gravity when the holder‘ is inverted, whereby to eifect release cf'the pressure mec?um > from the cartridge into the outer container. the arrangement being such that said cap serves both to retain the holder within the outer container and to prevent removal of the earti'ldse fm the holderbyengagingtbeheadonsaidmovable rod.
