COMPLETE SPECIFICATION filed by the said John Henry Johnson at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 9th January 1866, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HENRY
JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS I am in possession of an Invention for "A NEW OR IMPROVED
DETERGENT TO BE USED IN THE WASHING OR CLEANSING OF WOOL," and have
petitioned Her Majesty to grant unto me, my executors, administrators,
and assigns, Her Royal Letters Patent for the same, and have made solemn
declaration that the said Invention is communicated to me from abroad
by Charles Dyonise Reinfeld, Chevalier of the Order of Saints Maurice and
Lazare, of Paris, in the Empire of France.
NOW KNOW YE, that I, the said John Henry Johnson, do hereby declare

page_text: that the following Complete Specification under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in and by the following statement:-
"
The said Invention has for its object a more perfect and economical washing
or cleansing of wool, whether in the form of fleece or manufactured into
fabrics, and consists in the employment for that purpose of the peculiar
detergent substance herein-after described. This detergent substance is
obtained by making a solution of carbonate or salt of soda, and according to
the quality of the wool evaporating this solution to a density of 80 to 90
degrees of the alkalimeter. To this solution is added powdered "soap wort
(saponaire), in the proportion of from two-fifths to three-fifths of the weight
of the solution. The result is a substance resembling vegetable soap. By
the use of this detergent the washing or cleansing of the wool and the
removal therefrom in a perfect manner of all fatty or oily matters may be
accomplished with cold in lieu of hot water whatever may be the temperature
of the atmosphere at the time, whilst the natural elasticity of the wool is at
the same time preserved.
Another advantage in the use of this detergent is its great economy, as by
it a saving of from 60 to 200 per cent. in the cost of the materials is effected.
The saving of labor is also considerable, as the detergent above described
enables the operation of cleansing the wool in less time and in a more effectual
manner than by the ordinary methods.
Having now described and particularly ascertained the nature of the 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,-
First, the application and use to and in the washing and cleansing of wool
in cold water of the peculiar detergent herein-before described.
Second, the manufacture of the herein described peculiar detergent,
substantially as and for the purpose specified.
In witness whereof, I have to this my Specification hereunto set my
hand and seal, the Sixth day of January, One thousand eight hundred
and sixty-six.
