PROVISIONAL SPECIFICATION.
Improvements in Treating or Seasoning New and Purifying Old of
Foul Casks, Vats, Backs, or other Vessels.
I, HENRY HILL, of Parkside, Flodden Road, Camberwell, in the County of Surrey,
Brewer, do hereby declare the nature of this Invention, to be as follows:-
According to this invention I utilize the tannic acid or tannin and other astringent
material obtained from various vegetable substances for the production of a material
or materials which I have found suitable for seasoning or sweetening new, and
purifying and sweetening old or foul casks, vats, backs, and other wooden vessels, thus
also for treating casks or other vessels which have contained beer or other liquors, and
have been rinsed with water and dried, and are to be left unused for a time; also for
treating casks, or other vessels that have contained wine, beer, spirits, and some other
liquors, and have been similarly rinsed and dried, and which by treatment with my
astringent preparation may be rendered fit for receiving other liquors or substances
without imparting taste or odour thereto.
I obtain the material by decoction, infusion, or dilution by the aid of water, steam,
or spirits or other mode of extraction. The materials I use are tannic or gallic acid,
artificial tannic acid, or any vegetable substances containing tannic acid, gallic acid,
or other astringent substances. As examples of the latter I may mention oak bark,.
willow bark, elm bark, cutch, myrabolams, galls, catechu gun or wood, rhatany bark
or root, pomegranate rind or root, gambir, hops, kino.
The tannin material or solution may be combined or used in conjunction with
alkalies, thus forming tannates, and should be applied hot; but with the spirituous,
solutions heat is unnecessary. One or more applications are needed according to
circumstances, and I sometimes uso a final treatment with a solution of chloride of
lime, or bisulphite of lime, either singly, consecutively, or in conjunction, or with a
solution of permanganate of potassium, or of chloride of zinc or other suitable
disinfecting agent.

Improvements in Treating or Seasoning New and Purifying Old or
Foul Casks, Vats, Backs, or other Vessels.
I, HENRY HILL of Parkside, Flodden Road Camberwell in the County of Surrey,
Brewer 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 :-
According to this invention I utilize the tannic acid or tannin and similar material
obtained from various vegetable substances for the production of a material or
materials which I have found suitable for seasoning or sweetening new, and purifying
and sweetening old or foul casks, vats, backs, or other vessels. Also for treating casks
or other vessels which have contained beer or other liquors and have to be left unused
for a time. Also for treating casks or other vessels that have contained wine, beer,
spirits and some other liquors and which by treatment with my aforesaid preparation
are rendered fit for immediately receiving such or other liquors or substances without
imparting taste or odour thereto.

page_text: I obtain the aforesaid tannic material by decoction, infusion or dilution by the aid
of water steam or spirits or by other suitable modes of treatment.
I obtain the desired material from tannic or gallic acid, artificial tannic acid or any
vegetable substances containing tannic acid, gallic acid or other similar substances.
As examples of the latter I may mention oak bark, willow bark, elm bark, cutch,
myrabolams, galls, catechu, gum or wood rhatany bark or root, pomegranate rind
or root, gambier, hops, kino. The tannin material or solution should be combined or
used in conjunction with alkalios, thus forming tannates and be applied hot, but with
the spirituous solutions heat is unnecessary. One or more applications are needed
according to circumstances..
As a suitable example I shall name concentrated extract of oak bark or other tannic
substance the said extract having a specific gravity of 11.50 and combined with about
one tenth its weight of soda or carbonate of soda or of potash.
For use dilute this material with water about 200 or 250 times its weight for beer,
wine or spirit casks or vessels making the solution rather stronger in the latter two
cases.
If I use tannic acid I dilute it with about 1200 to 150 times its weight of water.
I keep the cask hot by means of steam blown in occasionally for the space of two to
four days.
The treatment thus far described when applied to foul casks has to be repeated one
or more times according to circumstances.
After emptying and rinsing the cask I next treat it with a chloride of lime solution
about one ounce to 36 gallons of water, cold or hot. The cask having been then
emptied and rinsed I treat it with a bisulphite of lime solution of about 10-30 specific
gravity.
Instead of the treatment with solution of chloride of limo and then with a solution
of bisulphite of lime I may treat with a solution of permanganate of potash or soda
about one of the permanganate to 250 of water by weight. Or instead of this I may
use a chloride of zinc solution of a strength of about one part chloride of zinc in 150
parts water by weight.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
First The employment of tannic solutions prepared and applied substantially as
set forth for the purification of foul beer wine and spirit casks and other vessels for
the seasoning and sweetening of new casks and other vessels and for rendering used
casks and other vessels fit to receive the same or other liquors.
Second-The mode of treating foul beer wine and spirit casks and other vessels.
consisting in treating with tannic solution then with chloride of lime solution and then
with bisulphite of lime solution, substantially as set forth.
Third: The mode of treating foul beer wine and spirit casks and other vessels
consisting in treating with tannic solution and then with a solution of permanganate
of potash or of soda or a solution of chloride of zinc, substantially as set forth.
