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

suspending the cartridge in the ?re extinguishing ' tion, other types of extinguishers such as soda
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.
The invention will now be described in detail 10
with reference to the, accompanying drawings,
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

medium from the shell. The cartridge 14 is pro

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
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

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

From‘the foregoing description it will be seen
that I have made new and useful improvements
in cages for holding or suspending stored pres
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
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

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

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

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.
