IMPROVEMENTS IN APPARATUS FOR EXTINGUISHING FIRE
Year: 1884

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 my said invention of "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 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 an efficient fire extinguisher upon what is known as the "Extincteur"
principle, or in place of the perforated cage the water may enter directly into
or he admitted through a perforated tube into the vessel itself containing the
impregnating chemicals and be so arranged that the water shall not have a direct
course out at the jet end but be compelled to thoroughly mix and become combined
with the chemicals. The jet end of the apparatus is so arranged that the end is
capable of removal for the purpose of introducing a fresh charge.
Although herein before described as applicable to a water supply under pressure
it will be obvious that this improved apparatus is capable of being combined with
a hand or power pump for the purpose of obtaining the requisite pressure and thus
the combined apparatus constitutes a hand or power chemical fire engine.

County of Lancaster, Engineer and machinery exporter, do hereby declare the
nature of my said invention of "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.
On the accompanying drawing Fig 1 represents a side and Fig 2 an end exterior
view of my improved fire extinguishing apparatus.
Figs 3 and 4 are side sectional views of the same.
:
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 c and also furnished with an outlet passage d leading to
the nozzle c. To the valve c is attached a length of flexible hose ƒ for forming a
connection with the water supply under pressure-For making this connection
I prefer to use that description of union known in the market as "Royle's Patent
Tap Union" but any ordinary screwed union or other connection might be
substituted. As all the foregoing is already covered by Letters Patent N° 9795
granted to me on the 5th day of July 1884 I do not claim any portion of the same
in the present application but instead of using a perforated cage as described in the
specification of my said former application I affix a perforated tube g as illustrated in
fig 3 to the inlet passage b through which the water enters directly into the vessel a
itself or I employ a chamber h (as seen in Fig 4 and in front sectional view Fig 5)
through which chamber the water passes and escapes through the perforations i
(drilled by preference at an angle as seen in Fig 5) into the vessel a. This
chamber is further provided with a tube j pointed at its extremity and there also
opening into the vessel a. This vessel a in this case contains the impregnating
chemicals which are introduced direct into such vessel itself through the removable
cover h which is secured and provided with a nozzle or outlet tube in a similar
manner to the cover described in my former specification.
By this application of a perforated tube 7 and of a perforated chamber h and
tube I secure that the water shall not have a direct course out at the jet
end but shall be compelled to thoroughly mix and become combined with the
impregnating chemicals.
Although hereinbefore described as applicable to a water supply under pressure
it will be obvious that this improved apparatus is capable of being combined with
a hand or power pump for the purpose of obtaining the requisite pressure and thus
the combined apparatus constitutes a hand or power chemical fire engine.
In this case it is however advisable and more convenient to have a length of
flexible hose & affixed at the outlet end d of the apparatus say as indicated in
Fig 6.

page_text: 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 combination and arrangement of vessel with a perforated tube
or chamber whereby the chemicals can be introduced direct into the impregnating
chamber substantially as and for the purposes herein before described.
2nd The combination of the aforesaid apparatus with a hand or power pump
thus constituting a hand or power chemical fire engine substantially as herein before
described.
