IMPROVEMENTS IN APPARATUS FOR EXTINGUISHING FIRE
Year: 1884

page_text: I ERNST GUSTAVUS REUSS, of Oak Road, Withington, near Manchester in the
county of Lancaster, Engineer and Machinery Exporter, do hereby declare the
nature of this my invention for IMPROVEMENTS IN APPARATUS FOR EXTINGUISHING
FIRE, to be as follows:-
The object of this invention is the construction of a simple and inexpensive
portable apparatus capable of being instantly attached to any water supply under
pressure, say a town's water pressure or cistern pressure and whereby a supply of
water impregnated with Carbonic Acid Gas may be instantly obtained for fire
extinguishing purposes.
In carrying out my invention I employ a vessel having inlet and outlet pipes
fitted with suitable valves or taps the former provided with a screwed or other
union for connecting to the water pressure whilst the outlet pipe has a nozzle at its
extremity. This vessel contains a perforated cage or vessel into which the necessary
dry chemicals are placed, for impregnating the water, as it circulates through, with
carbonic acid gas and thus such apparatus is always ready charged for use and only
requires to be connected to the nearest water tap under pressure to constitute a
most efficient fire extinguisher upon what is known as the "Extincteur" principle.

page_text: COMPLETE DI ECIFICATION,
I, ERNEST GUSTAVUS REUSS, of Oak Road, Withington, near Manchester, do
hereby declare the nature of my said Invention for "IMPROVEMENTS IN APPARATUS
FOR EXTINGUISHING FIRE" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of this invention is the construction of a simple and inexpensive
portable apparatus capable of being instantly attached to any water supply under
pressure or cistern pressure and whereby a supply of water impregnated with
carbonic acid gas may. be instantly obtained for fire extinguishing purposes.
In carrying out my invention I employ a vessel having inlet and outlet pipes
fitted with suitable taps the former provided with a screwed or other union for
connecting to the water pressure whilst the outer pipe has a nozzle at its
extremity.
This vessel contains a perforated cage or vessel into which the necessary dry
chemicals are placed for impregnating the water as it circulates through with
carbonic acid gas, and thus such apparatus is always ready charged for use and
only requires to be connected to the nearest water tap under pressure to constitute
a most efficient fire extinguisher upon what is known as the "Extincteur
principle.
"
On the accompanying drawing Fig. 1 represents a side sectional view Fig. 2 a
side elevation and Fig. 3 is a front end view of my improved Fire extinguishing
apparatus.
In all the views a is my improved portable fire extinguishing vessel formed by
preference of cast metal and provided with an inlet passage controlled by the
screw down inlet valve cand also furnished with an outlet passage d leading to the
nozzle e.
To the valve c is attached a length of flexible hose f for forming a
connection with the water supply under pressure say for instance to the screw
down bib stop valve g upon the town's main or connected to an overhead cistern.
In order to make the connection to the water supply I prefer to use that
description of union known in the market as Royles Patent Tap Union and
illustrated on Fig. 2 by the letter h-this union only requiring to be pushed on to
the bib of any ordinary water supply tap or valve and making its own joint-Any
ordinary screwed union or other connection might however be substituted as a
means of connecting the hose pipe f to the water supply.
The vessel a contains a perforated metallic cage i which is attached as illustrated
in Fig. 1 to the front removeable end or cover j of the apparatus-a tight joint
being secured by the insertion between the flange of a hard rubber leather or other
suitable packing ring k
In order to tighten the two flanges together a pair of projecting lugs or claws
and l'are formed upon the outer vessel a and a pair of segmental inclined planes m
and m¹ upon the outside of the cover j-these latter being cut away as illustrated
at the parts marked n and n' to enable the cover to pass the said projecting claws.
The cover being thus placed in position and turned in the direction of the arrow
(on Fig. 3) the inclined planes m and m³ will passage beneath and engage with
their respective projecting claws and land thus will draw the flange surfaces

page_text: together and effect the desired joint. This perforated cage i is designed to receive
the requisite chemical salts introduced through the movable cover i and to store up
the same ready for use-the perforated plate o serving to prevent the escape of the
solid chemical and the nozzle e being furnished with an annular rubber ring p and
a cap q to render the contents of the vessel air-tight and prevent the access of
moisture to the same. Instead of the nozzle e being formed upon the end cover j it
will be obvious that it might be connected at the extremities of a length of hose
pipe attached to the cover or any convenient part of the vessel and that in such
case instead of carrying the vessel a by means of the handle a¹ it could be placed
upon the floor leaving the hands at liberty to direct the jet.
The action of the improved Fire extinguishing apparatus may be described as
follows:-
The union being connected to the water supply and the valve g opened, the
vessel a can be carried by means of its handle a¹ to the scene of the fire, the valve o
being then opened the water will first enter the vessel a and passing through the
perforations will find its way into the cage i-here it will become impregnated
with the chemical salts contained therein, and as it issues through the plate o will
be charged with carbonic acid gas and may be directed by means of the nozzle on
to the fire. In this manner and by means of my improved apparatus I am enabled
to impregnate a large volume of water with carbonic acid and even when the
chemical salts are exhausted the extinguishing apparatus is still available for
throwing water only. It will be observed that the apparatus being charged with
dry chemicals remains ready for instant use and only requires to be connected to
the nearest water tap under pressure to constitute a most efficient Fire extinguisher
upon the "Extincteur principle."
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st The improved construction and arrangement of apparatus constituting a fire
extinguisher substantially as herein before described.
2nd The employing of a perforated cage for containing the necessary chemicals in
combination with the outer vessel provided with inlet and outlet passages sub-
stantially as and for the purposes herein before described and illustrated on the
accompanying drawing.
3rd The use and application to a water supply of a vessel charged with chemicals
whereby the water issuing from such supply can be impregnated with carbonic acid
gas substantially as and for the purpose herein before described.
