PROVISIONAL SPECIFICATION.
An Improved Method and Apparatus for the Prevention and Ex-
tination 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 to be as
follows:-
My invention relates to an improved method of and apparatus for collecting
and utilizing the carbonic acid gas which is generated during the process of all
fermentations for the purpose of preventing fires more especially those caused by
the carbonic acid
explosion of malt dust eto. in breweries, distilleries, etc.
gas (Co. 2) being a well known nonsupporter of combustion.
When the carbonic acid gas etc., is to bo 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 lovel 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 1 connect up to any machine vessel or part of the building
I wish to protect from fire by suitable pipes or ducts.
Where the manhole opening is fitted with loose or removable yeast bourds 1
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 1 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.
Where the machinery vessel or part of building to be protected is situated
above the fermenting vessel or source of the gas I provide a pump fan or blower
for raising the gas to the required lovel through the before mentioned pipes or
ducts.
I sometimes provide a storage vessel for the gas from which it can be withdrawn
as required.

tinction 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 collecting
and utilizing the carbonic acid gas which is generated during the process of all
termentations for the purpose of preventing fires mpre especially those caused by
explosion of malt dust etc., in breweries, distilleries and other like premises, the
carbonic acid gas (CO 2) being a well known nonsupporter of combustion.
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 fermenting vessel.
Fig. 2, is an elevation.
Fig. 3, is a plan of the top.
When the carbonic acid gas is to be collected from a
vessel a which has a manhole opening babove the surface of the liquid undergoing
fermenting or working
fermentation I provide a hopper or funnel shaped collecting head e 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 c.
The collecting head c I connect up to any machine, vessel or part of the building
I wish to protect from fire by suitable pipes e or duets.
I
Where the manhole opening is fitted with loose or removable yeast boards
prefer to make the yeast boards f box shaped open top and bottom and in such a
manner that they rest on the top of collecting head c and on one another to form
a channel down which the gas will fall, indicated by arrows in Fig. 1.
Where a sluice is used for the removal of yeast 1 provide a similar collecting
head arranged at the front of the overflow.
Where no manhole opening is provided in the side of a working vessel or of a
storage vessel I make an opening through the side connected up direct to the pipes
or ducts before described.
Where parachutes are used for collecting or skimming off the head from the
fermenting liquid I provide a trumpet mouthed pipe or duct passing down through
parachute pipe for taking off gas.
Where the machinery, vessel or part o building to be protected is situated
above the fermenting vessel or source of the gas I provide a pump, fan or blower
for raising the gas to the required level through the before mentioned pipes or
ducts.
I sometimes provide a storage vessel for the gas from which it can be withdrawn
as required.
It will be understood that the foregoing is given as an illustration of the im-
proved method of and apparatus herein before described, and that I may vary the
method and apparatus in many ways without departing from the nature of my
invention.
