I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
my invention to be as follows:-
:-
This invention relates to that class of fire extinguishing apparatus comprising a
metallic holder or receptacle, and chemicals contained in said holder and separated
from one another; part of said chemicals being contained in a glass bottle which is
adapted to be broken by devices provided for that purpose when the apparatus
is required for use, thereby mixing the chemicals and causing the generation of
gases which, with a liquid contained in said receptacle, are forcibly expelled from the
holder through a discharge nozzle.
.
The said invention has for one of its objects to preserve the different chemicals and
prevent loss of their potency in case they remain unused for a considerable length of
time, and also to prevent the possible injurious action of the chemicals on the
metallic holder and the faucet which controls the escape of the liquid and gases.
Another object of the said invention is to cause the automatic breakage of the
frangible vessel by the act of opening the discharge pipe to permit the escape of gas.
The invention also has for its object to provide an improved construction of the
apparatus whereby it may be more conveniently prepared for use, also to provide an
improved bottle, and holding devices therefor, and also to provide certain improvements
in the construction of the faucet.
To these ends the said invention consists partly in the combination with a main
holder or receptacle having a discharge orifice or passage and a cock or faucet therefor,
of two or more glass bottles, each containing a chemical, said bottles being, by
preference, hermetically sealed by the glass of which they are made, so that no leakage
or deterioration of their contents is possible when the bottles are intact. I prefer to
enclose each chemical, excepting such as have no injurious effect on the metal of the
Price 811

page_text: receptacle, in a separate bottle, so that none of the injurious chemicals will be in
contact with the main holder when the apparatus is not in use, and none of the
chemicals will be liable to suffer deterioration by leakage or mixture with the others.
The invention also partly consists in the combination with the receptacle, its
discharge spout, and the frangible vessel, of a spring-actuated plunger or hammer,
arranged so that when released it will break the vessel, and a movable detent which
holds said hammer against the face of its operating spring-When the apparatus is
ready for, but not in, use, said detent being moved by the valve or faucet controlling
the discharge pipe of the receptacle so that when said valve or faucet is opened the
hammer is released.
The invention also partly consists in the combination with the main receptacle, of
two or more bottles within said receptacle, and a spring hammer constructed to
break all of said bottles, said hammer being held against the force of an operating
spring when the apparatus is not in use, and released and thus caused to break the
bottles, when the apparatus is to be used.
The invention also partly consists in the combination with the main receptacle, of
two or more holders to contain the bottles, and a spring hammer formed to simultaneously
break all of the bottles held by said holders.
According to the said invention the receptacle is provided with a pipe leading
from the lower part of the interior of the said receptacle. to a faucet, where it is
secured to a tubular branch formed on the casing of the latter. Said casing has
another branch leading to the cover of the receptacle and there communicating with
an escape passage in the cover.
The plug of the faucet has a groove or way formed to connect the two branches,
when turned to one position, and to shut off communication between them when
turned to another position. To the lower end of the faucet-plug is attached an
arm which, when the faucet is closed, acts to support a spring plunger in a holder
formed with, or attached to, the faucet casing.
The faucet casing is rigidly attached in any suitable manner to a cap which is
screwed into the body of the receptacle, and constitutes the cover thereof.
I prefer to cast the cap casing and holder in one part. The socket formed in the
casing for the plug is extended through the top of the cover, so that the plug can be
inserted and removed through the top of the cover.
A plate is fitted to slide on the top of the cover and is secured thereto by a screw
inserted in the cover through a slot in said plate. The plate has a key-hole shaped
slot through which the stem of the plug passes. Said stem has two parallel sides at
the point where it passes through the slot and the narrower portion of said slot fits
closely against said parallel sides and prevents the stem from turning when the plate
is at one end of its movement. When the plate is moved so as to cause the wider end
of the slot to enclose the stem said stem is released and may be freely rotated. When
the stem is locked as above described, the plug is in position to close the faucet and
hold the plunger.
Instead of placing any of those chemicals which will exert an injurious effect on the
faucet or any metallic part of the apparatus directly in the receptacle and the rest in a
bottle or bottles, I prefer to place all of said chemicals in bottles using two or more as
may be desired, so that no part of the injurious chemicals will be exposed to the air
within the receptacle. Such chemical ingredients as are not injurious in their action
and not liable to deterioration by mixture with others may be placed in the receptacle.
Each bottle is hermetically sealed by the glass of which it is made after receiving its
contents, so that there can be no possibility of deterioration of the chemicals, nor of
destruction of the oil used to ensure an air-tight fit of the plug in its socket, by the
gases evolved from the chemicals.
I prefer to support the bottles in a series of holders, each composed of a ring or a
section of a ring attached to a pipe or other suitable support within the receptacle and
a series of spring fingers secured to said ring and formed to bear on the body of a
bottle, the lower part of said bottle preferably resting on the ring, although, if desired
the arms may project downwardly from the ring, so that the bottle will not rest on the

page_text: latter. To break said bottles when the apparatus is to be used, I arrange the plunger
so that when released it will strike all the bottles.
If desired, the plunger may be provided with a series of beaks extending over the
bottles, so that when the plunger is released by the turning of the plug said beaks will
simultaneously strike and break the bottles. In the present instance one of the said
beaks is attached directly to the plunger, and the others to an arm extending
downwardly from the plunger the whole constituting a multiple hammer. The arm is
preferably bent at its lower end and provided with two guide pins which pass through
eyes or sockets attached to the pipe, the arm being thus guided in its movements and
prevented from turning or swinging laterally. The bent lower portion of the arm may
be arranged to break one of the bottles.
My invention is not limited to the multiple hammer however, as the plunger may
be formed and arranged to pass successively through the bottles. The turning of the
plug to open the faucet releases the hammer and causes the breakage of the bottles
and the mixture of the chemicals, the result being a violent ejection of combined gas
and liquid through the escape nozzle.
It is obvious that two or any greater number of bottles may be employed as desired.
I do not limit myself to the provision of a separate holder for each bottle, as they
may be placed one upon the other in a holder common to them all, said holder being
for example a series of parallel vertical rods, or a tube suitably affixed to the receptacle.
A perforated partition is arranged in the receptacle just above its bottom. This
partition has a central orifice which receives the lower end of a pipe and constitutes a
strainer to prevent the fragments of glass and other foreign matter from entering the
pipe, and also a support which prevents said pipe from moving laterally, and
therefore protects the bottles by preventing them from striking against the sides of
the receptacle.

page_text: Improvements in Fire-extinguishing Apparatus.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to that class of fire extinguishing apparatus comprising a
metallic holder or receptacle and chemicals contained in said holder and separated;
a part of said chemicals being contained in a glass bottle which is broken by devices
provided for that purpose when the apparatus is to be used, the chemicals being thus
mixed and caused to generate gases which with liquid portion are forcibly expelled
from the holder through a discharged nozzle.
My invention has for its object first to preserve the different chemicals and prevent
loss of their potency in case they remain unused for a considerable length of time and
also to prevent the possible injurious action of the chemicals on the metallic holder
and the faucet which controls the escape of the mixed chemicals and gases.
The object of this invention is, secondly, to cause the automatic breakage of the
fragilo vessel by the act of opening the discharge pipe to permit the escape of gas.
The invention also has for its object to provide an improved construction of the
apparatus whereby it may be more conveniently prepared for use, also to provide an
improved bottle and holding devices therefor, and also to provide certain improvements
in the construction of the faucet.
To these ends the said invention consists first, in the combination with a main
holder or receptacle having a discharge orifice or passage and a cock or faucet
therefor; of two or more glass bottles each containing a chemical, said bottles being
by preference hermetically sealed by the glass of which they are made, so that no
leakage or deterioration of their contents is possible when the bottles are intact. I
prefer to enclose each chemical; excepting such as have no injurious effect on the
imetal of the receptacle, in a separate bottle, so that none of the injurious chemicals
will be in contact with the main holder when the apparatus is not in use, and none of
the chemicals will be liable to suffer deterioration by leakage or mixture with the
others.
The said invention also consists in a combination with the receptacle, its discharge
spout and the fragile vessel, of a spring-actuated plunger or hammer arranged so that
when released it will break the vessel, and a movable detent which holds said hammer
against the face of its operating spring when the apparatus is ready for, but not in
use, said detent being moved by the valve or faucet controlling the discharge pipe of
the receptacle, so that when said valve or faucet is opened the hammer is released.
The said invention also consists in the combination with the main receptacle of two
or more bottles within said receptacle, and a spring hammer constructed to break all
of said bottles, said hammer being held against the force of an operating spring when

page_text: the apparatus is not in use, and relcased and thus caused to break the bottles when the
apparatus is to be used.
The said invention also consists in the combination with the main receptacle of two.
or more holders to contain the bottles, and a spring hammer formed to simultaneously
break all of the bottles held by said holders, all of which I will now proceed to
describe.
.
In the accompanying drawings forming a part of this specification
Figure 1 represents a side elevation of my improved apparatus.
Figure 2 represents a vertical central section of the same.
Figure 3 represents a top view of the same, the stem of the faucet plug being-
shewn in section.
Figure 4 represents a sectional view of a different construction.
The same letters of reference indicate the same parts in all the figures.
a represents the receptacle. the pipe leading from the lower part of the interior
of the receptacle to the faucet c where it is secured to a tubular branch b formed
on the casing of the faucet. Said casing has another branch d leading to the cover of
the receptacle and there cominunicating with an escape passage d' in the cover as
shewn in Figure 2. The plug 2 of the faucet has a groove or way 3 formed to
connect the branches b, d when turned to one position and to shut off communication
between them when turned to another position. To the lower end of the faucet plug
is attached an arm g which when the faucet is closed acts to support a spring plunger /
in a holder i formed with or attached to the faucet casing. The faucet casing is
rigidly attached in any suitable manner to a cap k which is screwed into the body of
the receptacle and constitutes the cover thereof.
I prefer to cast the cap k, casing e and holder i in one part, as shown in Figure 2.
The socket formed in the casing e for the plug 2, is extended through the top of the
cover, so that the plug can be inserted and removed through the top of the cover.
n represents a plate fitted to slide on the top of the cover K and secured thereto by a
screw o inserted in the cover through a slot p in said plate. The plate has a key hole
shaped slot through which the stems of the plug passes, said stem has two parallel
sides at the point where it passes through the slot and the narrower portion of said
slot fits closely against said parallel sides and prevents the stem from turning when the
plato n is at one end of its movement. When the plate is moved so as to cause the
wider end of the slot r to enclose the stem s, said stem is released and may be freely
rotated. When the stem is locked as above described the plug 2 is in position to close
the faucet and hold the plunger-h.
Instead of placing any of those chemicals which will exert an injurious effect on the
faucet or any metallic part of the apparatus directly in the receptacle a, and the rest in
a bottle or bottles, I prefer to place all of said chemicals in bottles m using two or
more as may be desired, so that no part of the injurious chemicals will be exposed
to the air within the receptacle.
Such chemical ingredients are not injurious in their action and not liable to.
deterioration by mixture with others may be placed in the receptacle. Each bottle
is hermetically sealed by the glass of which it is made after receiving its contents, so
that there can be no possibility of deterioration of the chemicals, nor of destruction of
the oil used to ensure an air tight fit of the plug 2 in its socket, by the gases evolved
from the chemicals.
I prefer to support the bottles M in a series of holders, each composed of a ring or a
section of a ring 6 attached to the pipe 6 of other suitable support within the
receptacle and a series of spring fingers 7 secured to said ring and formed to bear
on the body of a bottle, the lower part of said bottle preferably resting on the ring 6,
although if desired the arms may project downwardly from the ring, so that the bottle
will not rest on the latter.
:
To break said bottles when the apparatus is to be used, I arrange the plunger i so
that when released it will strike all the bottles.
If desired the plunger may be provided with a series of beaks B, extending over the
bottles m, so that when the plunger is released by the turning of the plug 3, said

page_text: beaks 'will simultaneously strike and break the bottles as shown in Figure 4. In the
present instance one of said beaks is shown as attached directly to the plunger, and
the others to an arm A extending downwardly from the plunger the whole constituting
a multiple hammer. The arm A is preferably bent at its lower end and provided with
two guide pins p' p' which pass through eyes or sockets G, G, attached to the pipe b
the arm being thus guided in its movements and prevented from turning or swinging
laterally. The bent lower portion of the arm may be arranged to break one of the
bottles, as shown in Figure 4.
My invention is not limited to the multiple hammer, however as the plunger
may be formed as shown in Figure 2 and arranged to pass successively through the
bottles.
It will be seen that the turning of the plug to open the faucet releases the hammor,
and causes the breakage of the bottles and the mixture of the chemicals, the result
being a violent ejection of combined gas and liquid through the escape nozzle a'.
It is obvious that two or any greater number of bottles may be employed as
desired.
I do not limit myself to the provision of a separate holder for cach bottle, as they
may be placed one upon the other in a holder common to them all, said holder being
for example a series of parallel vertical rods, or a tube suitably affixed to the
receptacle. I represents a perforated partition in the receptacle a just above its
bottom. This partition has a central orifice which receives the lower end of the pipe bl
as shown in Figure 2. This partition constitutes a strainer to prevent the fragments
of glass and other foreign matter from entering the pipe ', and also a support which
prevents said pipe from moving laterally, and therefore protects the bottles by
preventing them from striking against the sides of the receptacle.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed as communicated to me by my
foreign Correspondent I declare that what I claim is :-
First. In a chemical fire extinguisher the combination of a receptacle having a
discharge spout and a valve or faucet therefor and containing a suitable chemical or
