IMPROVEMENTS IN DISTILLING AND RECTIFYING SPIRITS
Year: 1876

page_text: LETTERS PATENT to George Archbold, William John Cooper; and James Alfred
Wanklyn, all of Charlotte Street, Fitzroy Square, in the County of Middlesex,
Analytical Chemists, for the Invention of "IMPROVEMENTS IN DISTILLING
AND RECTIFYING SPIRITS."
Sealed the 1st September 1876, and dated the 18th March 1876.
PROVISIONAL SPECIFICATION left by the said George Archbold, William
John Cooper, and James Alfred Wanklyn at the Office of the Commissioners of
Patents on the 18th March 1876.
GEORGE ARCHBOLD, WILLIAM JOHN COOPER, and JAMES ALFRED WANKLYN, all of
Charlotte Street, Fitzroy Square, in the County of Middlesex, Analytical Chemists.
"IMPROVEMENTS IN DISTILLING AND RECTIFYING SPIRITS.
This Invention relates to the removal of the so called fusel oil, and of other
deleterious compounds or impurities, contained in impure spirits, so as to effect the
separation of such impurities during the process of distillation or of rectification,
and thereby obtaining a clean silent spirit without the production of feints, and it
consists in the employment and use of a compound known as Cooper's salts, or as
Cooper's disinfecting salts, mixed with either carbonate or with caustic potash, and
also with animal or with vegetable charcoal.
We also apply our Invention to the distillation of manufactured spirits such for
example as, brandy, rum, gin, and whiskey. In such cases the proportions of the
purifying agents employed, should be varied according to the condition of the
article operated upon, and the result it is desired to obtain. By the employment of
the aforesaid processes a more delicate flavor is imparted to the spirituous liquors,
which hitherto has been only attainable by age.

page_text: The said Invention relates to the removal of the so called fusel oil, and of other
deleterious compounds or impurities contained in impure spirits, so as to effect the
separation of such deleterious compounds or impurities, during the process of cis-
tillation or of rectification, and thereby obtaining a clean silent spirit, without the
production of feints, and it consists in the employment and use of a compound,
known as Cooper's salts, or as Cooper's disinfecting salts, mixed with either
carbonate or with caustic potash, and also with animal or with vegetable charcoal.
We also apply our Invention to the distillation of manufactured spirits, such for
example as brandy, rum, gin, and whiskey; in such cases the proportions of the
purifying agents employed, should be varied according to the condition of an article
operated upon, and the result it is desired to obtain. By the employment of the
aforesaid processes, a more delicate flavor is imparted to the spirituous liquors,
which hitherto has only been attainable by age.
In carrying out this Invention in addition to the ordinary materials now
employed in the distillation and rectification of spirits, we add what we have termed
and what is known in commerce as Cooper's salts, consisting essentially of the chlorides
of the alkaline earths, together with the chlorides of the alkalics. The proportions in
which the same are or may be employed, are about 112 lbs. of such salts to about
2,000 gallons of crude spirit, but we do not confine ourselves to these proportions,
as other proportions may in some cases with advantage be adopted.
In applying our Invention to the preparation of gin, we place in the distillatory
apparatus, together with the juniper berries and the spirit, about 14 lbs. of coni-
mercial carbonate of potash, and about 40 lbs. of the before mentioned Cooper's salts
or mixtures of the chlorides of the alkaline earths, and of the alkalies corresponding
thereto, and in above the same proportions, which salts or compounds we employ
in about the before-mentioned proportions to about every 1,000 gallons of spirits.
Having now described and particularly ascertained the nature of our said Inven-
tion, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the herein-before
in part recited Letters Patent is,-
Effecting improvements in distilling and rectifying spirits, by the employment
either alone or in conjunction with the materials now usually emyloyed, for effecting
the purification of crude or of rectified spirit of the salts known as Cooper's salts
or of mixtures of the chlorides of the alkaline earths, and of the alkalies, sub-
stantially in the manner hercin-before described.
In witness whereof, we, the said William John Cooper and James Alfred
Wanklyn, on behalf of ourselves and of the said George Archbold, have to
this our Specification set our hands and seals, this Fifth day of September,
One thousand eight hundred and seventy-six.
