Improvements in Fire Extinguishers.
I, GEORGE MORDAUNT, of the Firm of Mordaunt Brothers, of 1A, St. Helen's
Place, in the City of London, Merchants, do hereby declare the nature of this
invention to be as follows:-
This invention relates to fire extinguishing apparatus for use with chemicals,
and one object, among others, is to provide new and improved means for govern-
ing the acid receptacle in fire extinguishers using acids.
This invention includes the combination of a receptacle or cylinder having a
screw cap at one end and an outlet at the other end, a frame within the receptacle
and secured to the cap, an inner receptacle or bottle mounted in said frame on
studs taking into indentations in the sides of such inner receptacle, a movable
cap to cover the mouth of the inner receptacle provided with a stem extending
through the said screw cap.
This invention further includes the combination of a cylinder and apparatus
such as above described with the wheels and axle of a carriage upon the axle of
which it is mounted horizontally.
And this invention further comprises certain other combinations of parts herein-
after mentioned.
The body of the apparatus consists of an elongated metal receptacle or cylinder
preferably made of what is known as aluminium steel, which is capable of with-
standing considerable pressure without having great weight, and I find that such
cylinder may conveniently be made to contain about 30 gallons when it is to be
mounted on wheels, but larger and smaller sizes may also be made particularly
for hand carriage. The ends of the cylinder are slightly spherical and in one end
is a large aperture which is closed by a screw cap, and at the other end an outlet
which is connected on the inside with a curved pipe which is perforated and.
constitutes a strainer to prevent clogging when discharging. The outlet is adapted
for connection with a hose and is provided with a cut off or stop-cock.
Secured to the before mentioned screw cap and projecting within the cylinder
is a U shaped frame or yoke made in two pieces with a suitable catch or coupling
at the junction of the parts. The inner sides of the frame intermediate in its
length are provided with lugs which project towards each other and which engage
in corresponding indentations in the sides of the inner receptacle, the bottle for
containing acid, such indentations being somewhat below its centre.
A 'stem
The acid bottle is preferably made of glass or other suitable non-corrodible
material and is provided with a cap or cover which fits over its mouth and is
provided with suitable packing to prevent leakage of the contents.
passes outwards from the said cover through the screw-cap and is threaded so
that it may be screwed out or in by means of a handle on its outer end. By.
turning the stem so as to screw it outwards, when the cover closes the bottle, the
cover will be removed from the bottle and the bottle will revolve on the lugs of

page_text: the frame, owing to the greater weight of the upper part of the bottle or the
end having the mouth, and discharge the contents of the bottle into the large
receptacle where it mixes with the contents thereof, liberating carbonic acid gas
and thereby setting up considerable pressure, and the solution is then ready to
be discharged through the outlet. The before mentioned screw-cap is provided
with a suitable stuffing box through which the stem passes.
The strainer in the bottom of the cylinder is preferably curved to one side so
that when the cylinder lies in a horizontal position, as it does when mounted on
the wheeled carriage, it will convey substantially all the contents, the fire extin-
guishing solution to the outlet. When the apparatus lies in a horizontal
position the acid bottle will not when released from its cap turn completely
over, but will turn sufficiently to empty its contents into the soda solution in the
larger vessel.
When large cylinders such as those before mentioned are to be used and to
allow of their being conveyed readily and quickly, I preferably mount two or
more, side by side, in a horizontal position upon an axle of a two wheeled vehicle,
and provide this vehicle with a suitable tongue and ropes when it is to be drawn
by hand or with shafts when it is to be drawn by a horse. A pipe joins the
two outlets at the rear end of the vehicle to which pipe the hose is connected.
The hose may be carried coiled in a wire cage on the top of or over the cylinders.
A seat and a foot rest are provided for the driver in advance of the cage.
It will be obvious that small hand extinguishers also be mounted on the vehicle
or other receptacles containing chemicals, or the like.
By thus carrying two or more cylinders one may be re-charged while the other
is being discharged, thus keeping up a continuous stream on the fire.

I, GEORGE MORDAUNT, of the Firm of Mordaunt Brothers, of 1A, St. Helen's
Place, in the City of London, Merchants, 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 fire extinguishing apparatus for use with chemicals,
and one object, among others, is to provide new and improved means for govern-
ing the acid receptacle in fire extinguishers using acids.
This invention includes the combination of a receptacle or cylinder having a
screw cap at one end and an outlet at the other end, a frame within the recep-
tacle and secured to the cap, an inner revoluble receptacle or bottle mounted in said
frame on studs taking into indentations in the sides of such inner receptacle and
a moveable cap to close the mouth of the inner receptacle provided with a stem
extending through the said screw cap.
This invention further includes the combination of a cylinder and apparatus such
as above described with the wheels and the axle of a carriage upon the axle of which
it is mounted horizontally.
And this invention further comprises certain other combinations of parts herein-
after mentioned.
The invention will be best understood by reference to the accompanying draw-
ings in which
Fig. 1 is a horizontal section of one of the improved fire extinguishers with the
acid container closed, as when the apparatus is out of, but ready for use.

page_text: Fig. 2 is a view of the said apparatus in vertical section showing the acid-con-
tainer released and open as when the apparatus is in use and
Figs. 3 and 4 are respectively a back end elevation and a side elevation of a
hand-drawn vehicle provided with several fire extinguishers of the construction
shown in Figs. 1 and 2.
Like letters of reference indicate like parts throughout the drawings.
As shown most particularly in Figs. 1 and 2 of the drawings the body of the
apparatus consists of an elongated metal receptacle or cylinder A preferably made
of what is known as aluminium steel, which is capable of withstanding considerable
pressure without having great weight, and I find that such cylinder may con-
veniently be made to contain about 30 gallons when as shown in Figs. 3 and 4
it is to be mounted on wheels, but larger and smaller sizes may also be made
particularly for hand carriage. The ends of the cylinder A are or may be sub-
stantially hemispherical and in one end is a large aperture which is closed by a
screw cap A, and at the other end an outlet a which is connected on the inside
with a curved pipe a¹ which is perforated and constitutes a strainer to prevent
clogging when discharging.
The outlet a is adapted for connection with a hose and is provided with a valve
or stop-cock a Figs. 3 and 4.
Secured to the before mentioned screw cap A and projecting within the
cylinder A is a U shaped frame or yoke B made in two pieces with a suitable
catch or coupling b at the junction of the parts. The inner sides of the frame
at or near the middle of its length are provided with pivots or lugs which pro-
ject towards each other and engage in corresponding indentations c in the sides
of the inner receptacle or bottle for containing acid, such indentations being
somewhat below the centre of the bottle or nearer to the closed end than to the
mouth thereof.
The acid bottle C is preferably made of glass or other suitable non-corrodible
material and is provided with a cap or cover 1 which as shown in Fig. 1 fits over
its mouth and is provided with suitable packing d to prevent leakage of the con-
tents. A stem d¹ passes outward from the said cover 1 through the screw cap A¹
and is threaded so that it may be screwed out or in by means of a handle d² on its
outer end. By turning the stem so as to screw it outwards, when the cover D
closes the bottle C, the cover will be removed from the bottle and the bottle will,
as shown in Fig. 2, turn on the lugs b' of the frame B, owing to the greater weight
of the upper part of the bottle or the end having the mouth; by these means the
contents of the bottle will be discharged into the large receptacle A and become
mixed with the contents of the said receptacle whereby carbonic acid gas will
be liberated and considerable pressure generated so as to render the solution
ready for discharge through the outlet a. The before mentioned screw cap A¹
is provided with a suitable stuffing box a³ through which the stem d passes.
The strainer a¹ in the bottom or outlet end of the cylinder A is preferably
curved to one side so that when the cylinder lies in a horizontal position as it
does when mounted on the wheeled carriage, as shown in the drawings, it will
convey substantially all the contents, the fire extinguishing solution to the out-
let a.
When the apparatus lies in a horizontal position the acid bottle C need not,
when the cap D is released from it, turn completely over, but will turn sufficiently
to empty its contents into the soda solution in the larger vessel A.
When large cylinders such as those before mentioned are to be used, and to
allow of their being conveyed readily and quickly, I preferably mount two or more,
side by side, in a horizontal position upon an axle of a two wheeled vehicle E
as shown in Figs. 3 and 4 and provide this vehicle with a suitable tongue e and
other devices such as ropes when it is to be drawn by hand, or, with shafts when
it is to be drawn by a horse.
A pipe a joins the two outlets a between the valves a² at the rear end of the
vehicle to which pipe the hose F is connected.

page_text: The hose may be carried coiled in a wire cage G on the top of or over the
cylinders A. A seat and a foot rest are provided for the driver in advance of
the cage when the vehicle is to be drawn by a horse.
As shown in Figs. 3 and 4 small hand extinguishers H may also be mounted
on the vehicle. or other receptacles containing chemicals, or the like may be
carried thereon.
At the front end of the vehicle a fixed rail I may be provided for supporting
and guiding a funnel I' as shown in Fig. 4, which latter may be used for filling
the two cylinders A, being moved from one to the other cylinder according as
they require filling.
By thus carrying two cylinders as previously described one may be re-charged
while the other is being discharged, thus keeping up a continuous stream on the
fire, the two valves a serving for controlling their respective operations.
If desired more than two cylinders A may be mounted on the vehicle and all
these may be so connected that any one or more may be brought into operation
independently of the other or others.
The construction of the smaller extinguishers H shewn in Figs. 3 and 4 may
be the same as that illustrated in Figs. 1 and 2 the acid containers therein being
pivotted at such parts that when they are released by the removal of the cover
or other device closing their mouths they will immediately turn upside down;
this result may be attained either in the manner previously described and shown
in the accompanying drawing or by otherwise pivotting the acid container out
of balance as for example by pivotting it out of line with its axis or in other
words nearer to one side than the other.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I claim
is;
1. In a fire extinguisher the combination with a receptacle of another recep-
tacle so mounted or pivotted within it that when it is released it will heel over
and discharge its contents into the outer receptacle substantially as hereinbefore
described.
2. In a fire extinguisher the combination with a receptacle having another recep-
tacle pivotted within it in such manner that it heels over if left otherwise unsup
ported, of a cover such as D for the mouth of the inner receptacle and means
operated from the outside of the outer receptacle for removing the cover from
the mouth of the inner receptacle substantially as hereinbefore described with
reference to the accompanying drawings.
3. In a fire extinguisher the combination with a receptacle having
a cap such
a A¹, of a frame or yoke secured to the cap, a receptacle such as C pivotted in the
frame, and a screw passing through the cap and having on one end a cover for
the inner receptacle and on the other end means whereby it may be turned for
moving the cover in relation to the said inner receptacle substantially as herein-
before described with reference to the accompanying drawings.
4. A complete fire extinguishing apparatus arranged substantially as herein-
before described and illustrated in Figs. 3 and 4 of the accompanying drawings.
