IMPROVEMENTS IN APPA
Year: 1865

page_text: LETTERS PATENT to Carl Johan Falkman, of St. Petersburg, in the
Empire of Russia, but now residing at No. 1*, Craven Street, Strand, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN APPA-
PROVISIONAL SPECIFICATION left by the said Carl Johan Falkman ȧt
the Office of the Commissioners of Patents, with his Petition, on the
1st March 1865.
I, CARL JOHAN FALKMAN, of St. Petersburg, in the Empire of Russia, but
now residing at No. 14, Craven Street, Strand, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR DISTILLING, PURIFYING, AND STORING SPIRITUOUS LIQUORS," to be
as follows:-
Apparatus for distilling and purifying spirituous liquors, as also for storing
the same after distillation, have heretofore been made either of wood, iron,
copper, or tin. Apparatus constructed of the first-named material are of a
very perishable nature; those of iron are very objectionable, on account of
the rapid oxydation of that metal; and those of copper or tin are necessarily
of a very expensive nature.
Now my present Invention consists in constructing such distilling, purifying,
and storing apparatus of zinc, I having found by experiment that this metal

page_text: has no injurious effect upon spirituous liquors distilled, purified, or stored in
apparatus made of the same. Such apparatus may either be made entirely
of zinc, or they may be made of wood or iron, lined or covered with zinc.
When made entirely of zinc, they are constructed in the same manner as
those made of copper, the plates or sheets being joined together by soldering
or by rivetting, or by both, and those parts that require greater strength than
is afforded by. zine alone, I make of iron or copper, well coated on all surfaces
with zinc, so as to prevent galvanic action from taking place.
The zinc employed for this purpose should be free from such substances
that would act injuriously upon the spirituous liquors, but I have found that
the ordinary sheet zinc of commerce is sufficiently pure for this purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Carl Johan Falkman in the Great Seal Patent Office on the
81st August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CARL JOHAN
FALKMAN, of St. Petersburg, in the Empire of Russia, but now residing at
No. 14, Craven Street, Strand, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of March, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Carl Johan Falkman, Her special licence that I, the said Carl
Johan Falkman, my executors, administrators, and assigns, or such others
as I, the said Carl Johan Falkman, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time.
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN APPARATUS FOR DISTILLING, PURIFYING, AND STORING
SPIRITUOUS LIQUORS," upon the condition (amongst others) that I, the said
Carl Johan Falkman, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Cal Johan Falkman, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
Apparatus for distilling and purifying spirituous liquors, as also for storing
the same after distillation, have heretofore been made either of wood, iron,
copper, or tin. Apparatus constructed of the first-named material are of a
very perishable nature; those of iron are very objectionable, on account of
the rapid oxydation of that metal; and those of copper or tin are necessarily
of a very expensive nature.
Now my present Invention consists in constructing such distilling, purifying,
and storing apparatus of zinc, I having found by experiment that this metal
has no injurious effect upon spirituous liquors distilled, purified, or stored in
apparatus made of the same. Such apparatus may either be made entirely of
zinc, or they may be made of wood or iron, lined or covered with zinc. When
made entirely of zinc, they are constructed in the same manner as those made
of copper, the plates or sheets being joined together by soldering or by rivetting,
or by both, and those parts that require greater strength than is afforded by
zinc alone I make of iron or copper, well coated on all surfaces with zinc, so
as to prevent galvanic action from taking place.
The zinc employed for this purpose should be free from such substances
that would act injuriously upon the spirituous liquors, but I have found that
the ordinary sheet zinc of commerce is sufficiently pure for this purpose.
Having now described the nature of my Invention, and in what manner the
same is to be performed, what I claim under the herein-before in part recited
Letters Patent is,-
First, constructing apparatus for distilling, purifying, and storing spirituous
liquors of zinc.
Second, constructing apparatus for distilling, purifying, and storing spirituous
liquors of iron or wood, lined or coated with zinc.
In witness whereof, I, the said Carl Johan Falkman, have hereunto
set my hand and seal, this Twenty-second day of August, in the year
of our Lord One thousand eight hundred and sixty-five.
CARL JOHAN FALKMAN. (L.B.)
