Year: 1860

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "AN IMPROVED LIQUID PREPARATION OF TOBACCO,"
-A communication from abroad by George Jaques, of Somerville,
County of Middlesex and State of Massachusetts, United States of
America.
Scaled the 24th August 1860, and dated the 19th May 1860.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton at
the Office of the Commissioners of Patents, with his Petition, on the
19th May 1860.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Mechanical Draughtsnian, do hereby declare the
nature of the said Invention for "AN IMPROVED LIQUID PREPARATION OF TOBACCO,"
to be as follows:-
The object of this Invention is the preparation of a decoction of tobacco in
a highly concentrated form to be applied to the destruction of vermin, and for
the removal of cutaneous diseases from sheep and other animals. To this end
tobacco (preference being given to that which is very strong) is placed in a
still, and covered with water. Heat or steam is then applied, and the still is
run until a strong solution of the tobacco is forined and has become con-
centrated by the evaporation of a portion of the water which is distilled
over, carrying with it nicotine and volatile oils, which are collected and
condensed.
The contents of the still are now discharged, the liquid drawn off, and the
residue pressed to extract all the juice. This being added to the solution the
whole is concentrated by evaporation, and, if necessary, to this extract the
[Price 8d.

page_text: nicotine and volatile oils obtained in the distillation are added. The pre-
paration will then contain all the active principles, volatile as well as soluble,
which can be obtained from the tobacco, and may be used without farther
preparation, and transported at a comparatively small expense. Alcohol, ether,
and alkaline solutions may be used in place of water, but the aqueous process
is preferred on account of its cheapness.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office on
the 17th November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of May, in the year of our Lord
1860, in the twenty-third year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said Alfred Vincent Newton,
Her special license that I, the said Alfred Vincent Newton, my executors
administrators, and assigns, or such others as I, the said Alfred Vincent
Newton, 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 "AN IMPROVED LIQUID
PREPARATION OF TOBACCO," being a communication to me from abroad by George
Jaques, of Somerville, County of Middlesex, and State of Massachusetts,
United States of America, upon the condition (amongst others) that I, the said
Alfred Vincent Newton, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, aud cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of tho said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Decoctions of tobacco have been employed for the purpose of destroying
parasitic animals, and large quantities of this plant are imported into sheep-

page_text: growing countries at considerable expense for freight and transportation for
this purpose. To save this expense of transportation, and to relieve the
farmer of the disagreeable and tedious labor of preparing the decoction, I
have invented a new article of manufacture, consisting of a preparation of
tobacco in a highly concentrated form, the method of preparing which I will
now proceed to describe.
Tobacco of any description, preference being given to that which is very
strong, is placed in a still, and with a quantity of water sufficient to cover it.
Heat or steam is applied, and the still is run until a strong solution of the
tobacco is forined and has become concentrated by the evaporation of a portion
of the water, which is distilled over, carrying with it nicotine and volatile oils,
which are condensed and afterwards collected by a suitable process.
The contents of the still are now discharged, the liquid drawn off, and the
residue pressed to extract all thejuice, which is mixed with the solution, which
is afterwards concentrated by evaporation; ifnecessary to this extract is added
the nicotine and volatile oils which have been produced or separated by
distillation. The preparation thus contains all the active principles, volatile
as well as soluble, which can be obtained from the tobacco, and may bo
used without further preparation, and transported at a comparatively small
expense. I have also made use of alcohol, ether, and alkaline solutions in
place of water, but prefer the aqueous process on account of its cheapness.
Having now set forth the nature of this Invention, and explained the
manner of carrying the same into effect, I wish it to be understood that under
the above recited Letters Patent I do not claim boiling or macerating tobacco
in water for the purpose of making a sheet or leaf, and soaking the same in
the decoction thus made, or in water distilled therefrom; but what I do
claim as a new article of manufacture is, the within-described preparation
of tobacco, consisting of the soluble and volatile portions, as set forth.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Fifteenth day of November, in the year of
our Lord One thousand eight hundred and sixty.
Witness,
J. W. MOFFAIT,
