Melcombe Place Dorset Square in the County of Middlesex for an invention
of IMPROVEMENTS IN THE METHOD OF AND MATERIALS FOR PURIFYING CASKS
AND OTHER RECEPTACLES. AND FOR DRESERVING THEM FROY TALLING
PROVISIONAL SPECIFICATION left by the said John La Mert & Braham
La Mert at the Office of the Commissioners of Patents on the 8th June
1882.

Square in the County of Middlesex "IMPROVEMENTS IN THE METHOD OF AND
MATERIALS FOR PURIFYING CASKS AND OTHER RECEPTACLES AND FOR PRESERVING
THEM FROM FOULING
"
According to our invention we first coat the insides of casks and other receptacles
such as crates meat safes and the like with a mixture of shellac or similar gums or
combinations thereof, alcohol or wood spirit, and powdered charcoal, and we then
set fire to or "flare" such coating, allowing it to burn until the alcohol is consumed
and the surface of the wood becomes slightly charred. By this means casks or
receptacles that have become foul from previous use are effectually purified, while
new casks or receptacles so treated are preserved from fouling for a long time.
The casks may be repeatedly treated in the above described manner as often as
may be required.
The proportions of the ingredients for the above described compound which we
have found to answer in practice are shellac from 1 to 4 parts by weight alcohol
from 2 to 10 parts and charcoal from 1 to 4 parts but we do not limit ourselves to
these proportions.
In combination with the said compound we also sometimes use an antiseptic
such as boracic or salicylic acid, or any other of the known antiseptics or
combination of such, which we either mix with the said compound, or apply
separately in either an aqueous or alcoholic solution; if the latter is used we again
flare, as with the other compound
Our invention is specially applicable to what is known in the trade as stinking
casks or "stinkers," and in treating these it may be sometimes found advantageous
to wash or steam them in the first instance, although we have obtained perfect
results without any such previous treatment.

دو
According to our Invention we first coat the insides of casks, barrels, flour
barrels and other receptacles such as crates meat safes and the like with a mixture
of shellac or similar gums or combinations thereof, alcohol or wood spirit, and
powdered charcoal, and we then set fire to or "flare" such coating, allowing it to
burn until the alcohol is consumed and the surface of the wood becomes slightly
charred. By this means casks or receptacles that have become foul from previous
use are effectually purified, while new casks or receptacles so treated are preserved
from fouling for a long time. The casks may be repeatedly treated in the above
described manner as often as may be required.
The proportions of the ingredients for the above described compound which we
have found to answer in practice are shellac from 1 to 4 parts by weight alcohol
from 2 to 10 parts and charcoal from 1 to 4 parts but we do not limit ourselves to
these proportions.
In combination with the said compound we also sometimes use an antiseptic
auch as boracic acid or salicylic acid or any other of the known antiseptics or
combination of such, which we' either mix with the said compound or apply
separately in either an aqueous or alcoholic solution; if the latter is used we again
flare, as with the other compound.
Having thus described the nature of our Invention and in what manner the
same is to be performed we claim :-
First. Purifying casks and other receptacles by first coating them with a.
mixture of shellac or similar gums or combinations thereof, alcohol or wood
spirit and powdered charcoal and then setting fire to or "flaring" such coating,
substantially as herein described.
Second. The manufacture of a compound for purifying casks consisting of shellac.
or similar gums or combinations thereof, alcohol or wood spirit and powdered
charcoal, substantially as herein described.
Third. In combination with the process of purifying casks by means of a
compound formed of shellac or other gums, alcohol or wood spirit and powdered
charcoal the use of an antiseptic such as boracic or salicylic acids, either mixed
with the said ingredients or employed as a separate coating substantially as herein
described.
In witness whereof I the said John La Mert have hereunto set my hand
and seal this Sixth day of December in the year of Our Lord One thousand
eight-hundred and eighty-two.
