in means for purifying casks and the
Year: 1898

page_text: I, THOMAS WHITING, of Cross Bargain Farm, Sparsholt, in the County of Berkshire,
Dairy Farmer, do hereby declare the nature of this invention to be as follows:
-
This invention for improvements in means for purifying casks and the like has for
its object to purify beer porter casks or barrels and the like, which have become
tainted or stale, from exposure or disuse or other causes and which are known in the
brewing trade as stinkers, such receptacles being rendered unfit for the storage of beer,
porter or any other liquid intended for human consumption.
According to this invention a stinker cask or other foul receptacle is filled with or
immersed in lactic acid, whey, obtained from milk, or other compound or product in
which lactic acid is the predominating constituent, at a suitable temperature under
any desired pressure and for a period sufficient to destroy the fungous growth, or sub-
stance forming the fouling material, such period depending on the nature of the
material of which the receptacle is constructed, the degree of foulness etc.
Preferably the cask or other receptacle is left open during treatment in order that
the exposure to the atmosphere may increase fermentation and thereby facilitate and
intensify the purifying action. After this treatment has been continued for a
suitable period the cask is removed and thoroughly cleansed with water and dried
when it is again fit for use.

I, THOMAS WHITING, of Cross Bargain Farm, Sparsholt, in the County of Berkshire,
Dairy Farmer, 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 for improvements in means for purifying casks and the like, has for
its object to purify beer, porter, and the like casks or barrels which have become
tainted or stale from exposure or disuse or other causes and which are known in the
brewing trade as stinkers, such receptacles being rendered unfit for the storage of
beer, porter, or any other liquid intended for human consumption.
According to this invention a stinker cask or other foul receptacle is first thoroughly
dried and then filled with or immersed in lactic acid, whey obtained from milk or

page_text: other compound or product in which lactic acid is the predominating constituent, at
a suitable temperature under any desired pressure and for a period sufficient to des-
troy the fungous growth or substance forming the fouling material, such period de-
pending on the nature of the material of which the receptacle is constructed, the
degree of foulness, etc.
Preferably the cask or other receptacle is left open during treatment in order that
the exposure to the atmosphere may increase fermentation and thereby facilitate and
intensify the purifying action. After this treatment has been continued for a suit-
able period the cask is removed and thoroughly cleansed with hot water or steam and
dried when it is again fit for use.
Instead of treating the casks, etc. wholly they may be taken to pieces and the
parts treated separately.
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 :-
1. Treating stinker casks and the like with lactic acid or compounds or products
containing lactic acid, substantially as described for the purpose set forth.
2. Treating stinker casks and the like with whey obtained from milk, substantially
as described for the purpose set forth.
Dated this 22nd day of June 1899.
