IMPROVEMENTS IN THE MANUFACTURE OF INK
Year: 1865

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF INK."-A commu-
nication from abroad by Josiah Vincent Lavers, of Sydney, New South
Wales.
Sealed the 18th July 1865, and dated the 24th March 1865.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 24th March 1865.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF INK,"
to be as follows:-
This Invention of "Improvements in the Manufacture of Ink" consists in
combining with an aqueous extract or infusion of bruised Aleppo galls a
proper proportion of sulphate of iron, gum arabic, and cloves, and submitting
the liquid mixture drop by drop to the action of the air. The proportions in
which the several ingredients may be employed for the purposes of the

page_text: Invention admit of considerable variation, but as an ample, I may say that
to manufacture, say, 150 gallons of ink 120 lbs. of bruised Aleppo galls should
be placed in a suitable open vessel and covered with cold water, in which they
should be macerated for about 14 days. A sufficient quantity of boiling water
to make the required quantity of liquid is then added with 50 lbs. of green
sulphate of iron, 50 lbs. of gum arabic, and about 12 lbs. of cloves. After
these ingredients have been allowed to stand for a short time until the
sulphate of iron and gum arabic have become dissolved, the liquid is poured
into vessels provided with perforated bottoms, the holes in which are filled
with cotton wick or threads about a foot long, and which hang down there-
from. The liquid passes through the perforated bottoms of the vessels and
down the pendent threads, and is thus filtered, and in so doing becomes
exposed in minute subdivision to the action of the air, which fixes the colour
during the filtering process, instead of this result requiring months to effect,
as is now the case. The ink thus produced will be perfectly limpid and free
from sediment.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office on
the 23rd September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth 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 William Edward Newton, Her special licence that I, the said
William Edward Newton, my executors, administrators, and assigns, or such
others as I, the said William Edward 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 "IMPROVEMENTS IN THE MANUFACTURE OF INK," a communication
from Josiah Vincent Lavers, of Sydney, New South Wales, upon the condition
(amongst others) that I, the said William Edward Newton, my executors

page_text: per-
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
formed, 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..
:
NOW KNOW YE; that I, the said William Edward Newton, 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 (that is to say) :-
This Invention of "Improvements in the Manufacture of Ink.. consists in
combining with an aqueous extract or infusion of bruised Aleppo galls a
proper proportion of sulphate of iron, gum arabic, and cloves, and submitting
the liquid mixture drop by drop to the action of the air. The proportions in
which the several ingredients may be employed for the purposes of the
Invention admit of considerable variation, but as an example I may say that
to manufacture, say, one hundred and fifty gallons of ink one hundred and
twenty pounds of bruised Aleppo galls should be placed in a suitable open
vessel and covered with cold water, in which they should be macerated for
about fourteen days. A sufficient quantity of boiling water to make the
required quantity of liquid is then added, with fifty pounds of green sulphate
of iron, fifty pounds of gum arabic, and about twelve pounds of cloves. After
these ingredients have been allowed to stand for a short time until the
sulphate of iron and gum arabic have become dissolved, the liquid is poured
into vessels provided with perforated bottoms, the holes in which are filled
with cotton wick or threads about a foot long, and which hang down there-
from. The liquid passes through the perforated bottoms of the vessels and
down the pendant threads, and is thus filtered, and in so doing becomes
exposed in minute subdivision to the action of the air, which fixes the colour
during the filtering process, instead of this result requiring months to effect,
as is now the case. The ink this produced will be perfectly limpid and free
from sediment.
Having now described the Invention that has been communicated to me
from abroad, and having explained the manner of carrying the same into effect,
I would observe that I do not intend to limit myself to the use of the particular
ingredients herein-before mentioned for the manufacture of ink, as other well
known ingredients may be used for the purpose, nor do I intend to claim the
exclusive use of such ingredients for the manufacture of ink, but what I claim
as the Invention which I desire to secure by Letters Patent is, the mode

page_text: herein set forth of filtering the liquid so that during the filtering operation
such liquid may become exposed in a state of fine subdivision to the action of
the air for the purpose of fixing the colors. I claim this method of filtering
the liquid whatever ingredients may be employed in manufacturing the ink.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Twenty-third day of September, in the year
of our Lord One thousand eight hundred and sixty-five.
W. E. NEWTON. (L.s.)
