An Improved Method and Apparatus for the Extinction of Fires in
Breweries, Distilleries, and other like Premises.

İ, HARRY MASON KETTELWELL, of 352, High Road, Kilburn, in the County of
London, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of and apparatus for utilizing the
carbonic acid gas (Co²) which is generated during the process of all fermentations
for the purpose of extinguishing fires in breweries distilleries etc.
The means of
collection I employ are as follows:-
When the carbonic acid gas etc. is to be collected from a fermenting or working
vessel which has a manhole opening above the surface of the liquid undergoing
fermentation I provide a hopper or funnel shaped collecting head fixed outside and
about level with the lower edge or sill of manhole opening in such a manner that
the carbonic acid gas which is heavier than air flows over edge of sill and falls
into the collecting head.
The collecting head I connect up to the force pump hereafter mentioned by suit-
able pipes or ducts.
Where the manhole opening is fitted with loose or removable yeast boards I
prefer to make the yeast boards box shaped open top and bottom and in such a
manner that they rest on top of collecting head and on one another to form a
channel down which the gas will fall.
Where a sluice is used for the removal of yeast I provide a similar collecting
head arranged at the front of overflow.
Where no manhole opening is provided in the side of working vessel or of a
storage vessel I make an opening through side connected up direct to pipes or ducts
before mentioned.
Where parachutes are used for collecting or skimming off head from fermenting
liquid I provide a trumpet mouthed pipe or duct passing down through parachute
pipe for taking off gas.
I sometimes provide a storage vessel for the gas from which it can be withdrawn
as required.
For my purpose I provide a suitable shaped vessel which is filled or partly filled
with water and into which I pump the carbonic acid under pressure either directly
through an opening below the top level of the water or through an internal pipe
coil or rose.
The pipe or coil can be perforated so that the gas enters the water in a finely
divided state, the object being to get the water to take the gas into solution.
This vessel is intended to form a reservoir of chemicalized water as in the ordinary
chemical fire engine and I provide suitable outlets for the water with gas in solu-
tion for connection to the fire nozzles or mains which would be fixed throughout
the building and used in the way of ordinary water fire mains.

page_text: I provide a safety valve on the dissolving vessel for the escape of undissolved
gas, air or any other unsolvable gases given off from the fermenting vessels etc.
The pump for forcing the gases into the vessel can be any ordinary suitable pump
driven in any well known convenient way.
In place of a closed vessel I sometimes use an open one the gas being simply
forced into the water. The vessel being placed at or near the top of the building
the chemicalized water will fall by gravity where required.

An Improved Method and Apparatus for the Extinction of Fires in
Breweries, Distilleries, and other like Premises.
I, HARRY MASON KETTELWELL, of 352, High Road, Kilburn, in the County of
London, Engineer, 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;―
My invention relates to an improved method of and apparatus for utilizing the
carbonic acid gas (Co²) which is generated during the process of all fermentations
for the purpose of extinguishing fires in breweries distilleries etc. The means of
collection I employ are as follows:-
:-
When the carbonic acid gas etc. is to be collected from a fermenting or working
vessel which has a manhole opening above the surface of the liquid undergoing
fermentation I provide a hopper or funnel shaped collecting head fixed outside and
about level with the lower edge or sill of manhole opening in such a manner that
the carbonic acid gas which is heavier than air flows over edge of sill and falls
into the collecting head.
The collecting head I connect up to the force pump hereafter mentioned by suit-
able pipes or ducts.
Where the manhole opening is fitted with loose or removable yeast boards I
prefer to make the yeast boards box shaped open top and bottom and in such a
manner that they rest on top of collecting head and on one another to form a
channel down which the gas will fall.
Where a sluice is used for the removal of yeast I provide a similar collecting
head arranged at the front of overflow.
Where no manhole opening is provided in the side of working vessel or of a
storage vessel I make an opening through side connected up direct to pipes or ducts
before mentioned.
Where parachutes are used for collecting or skimming off head from fermenting
liquid I provide a trumpet mouthed pipe or duct passing down through parachute
pipe for taking off gas.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of the vessel.
Fig. 2, is a plan on line A, B.
I sometimes provide a storage vessel for the gas from which it can be withdrawn
as required.
For my purpose I provide a suitable shaped vessel a which is filled or partly

page_text: filled with water and into which I pump the carbonic acid gas under pressure
either directly through an opening or inlet b below the top level of the water or
through an internal pipe coil or rose.
'
The pipe or coil c can be perforated so that the gas enters the water in a finely
divided state the object being to get the water to take the gas into solution.
This vessel is intended to form a reservoir of chemicalized water as in the ordinary
chemical fire engine and I provide suitable outlet d for the water with gas in
solution for connection to the fire nozzles or mains which would be fixed throughout
the building and used in the way of ordinary water fire mains.
I provide a safety valve e on the top of the dissolving vessel for the escape of
undissolved gas, air or any other unsolvable gases given off from the fermenting
vessels etc.
The vessel a is constructed of a metallic cylindrical shape and rivetted to a
base and cover g with rings h. At the base I provide a stand on which the
vessel is placed. At the side of the vessel a near the top is fixed a gauge-glass j
and a pressure gauge k near the base. On the opposite side to the gauge-glass i
I attach the liquor inlet with a suitable valve m. The liquor outlet d is situated
at the base with a valve n.
The pump for forcing the gases into the vessel can be any ordinary suitable
pump driven in any well known convenient way.
In place of a closed vessel I sometimes use an open one the gas being simply
forced into the water. The vessel being placed at or near the top of the build-
ing the chemicalized water will fall by gravity where required.
It will be understood that I do not particularly tie myself to construct the vessel
to the exact shape, or that it should be of a vertical construction, as it is evident
that the various parts may be modified in many ways without departing from the
nature of my invention.
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
C
1. In an apparatus for the extinction of fires, the combination of the vessel a
inlet for carbonic gas coil c outlet d safety valve e base f cover g rings h stand i
gauge-glass pressure gauge k liquor inlet and valves m and n, substantially as
herein described and according to the accompanying drawing.
2. The method and apparatus for the extinction of fires in breweries distilleries
and other like premises, substantially as above described in this specification.
