the 1st December 1862.
I, PETER WILLIAM REUTER, of Buckland Crescent, Saint John's Wood, in
the County of Middlesex, Merchant, do hereby declare the nature of the
said Invention for "THE PREPARATION OF A NEW COMPOUND TO BE USED FOR
DYEING AND PRINTING PURPOSES," a communication from abroad by Edward
Reuter, of Paris, in the Empire of France, Color Manufacturer, to be as
follows:
This Invention consists in the preparation of a compound for producing a
brown color on wools by mixing oxide of lead or other compounds of lead with
lime.or potash or.carbonate of potash, or soda or. carbonate of soda, or baryta
magnesia, strontia, or other similar substances, which on being mixed with
water will form an alkaline solution of oxide of lead. This compound is
applicable to dyeing or printing wools, as in the ordinary manner, but in all
cases the goods to be printed should be subjected to the steaming process.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Peter William Reuter in the Great Seal Patent Office
on the 1st June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
WILLIAM REUTER, of Buckland Crescent, St. John's Wood, in the County of
Middlesex, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Peter William Reuter, Her special license, that I, the said
Peter William Reuter, my executors, administrators, and assigns, or such
others as I, the said Peter William Reuter, my executors, administrators;
or 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 "THE PREPARATION OF A NEW COMPOUND TO BE USED FOR DYEING
AND PRINTING PURPOSES," a communication from abroad by Edward Reuter, of
Paris, in the Empire of France, Color Manufacturer, upon the condition
(amongst others) that I, the said Peter William Reuter, my executors
or administrators, by an instrument in writing under my hand and seal,
or under the hand and seal of one of them, 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.
NOW KNOW YE, that I, the said Peter William Reuter, do hereby
declare the nature of my 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:-
My said Invention consists in the preparation of a compound for producing
a brown color on wools by mixing oxide of lead or other compounds of lead
with lime or potash or carbonate of potash, or soda or carbonate of soda, or
baryta, magnesia, strantia, or other similar substances, which on being mixed
with water will form an alkaline solution of oxide of lead. In practice it is
preferred to employ a compound consisting of one part of oxide of lead well
mixed with four parts of slaked lime made into a stiff paste with water.

page_text: When required for dyeing purposes, a portion of this compound is well
mixed with water in the dye bath previous to entering the wool. The wool is
then entered, and the dye liquor thus prepared heated until the wool begins to
be dyed; the wool is then turned till of the required shade.
For printing, this compound is thickened with a convenient thickening,
printed, and then steamed in the ordinary manner.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, the preparation of a compound or
compounds of lead, which on being mixed with water will produce an alkaline
solution of lead, and also the application and use of such compound or
compounds for the dyeing and printing of woollen fibres or fabrics.
In witness whereof, I, the said Peter William Reuter, have hereunto
set my hand and seal, this Twenty-ninth day of May, One thousand
eight hundred and sixty-three.
PETER WILLIAM REUTER. (L.S.)
