Year: 1862

page_text: LETTERS PATENT to Harper Twelvetrees, of Bromley, in the County
of Middlesex, Manufacturer, for the Invention of "IMPROVEMENTS IN
THE PREPARATION OF WASHING POWDERS, SOAP POWDERS, AND CLEANSING
CRYSTALS."
Sealed the 17th February 1863, and dated the 22nd August 1862.
PROVISIONAL SPECIFICATION left by the said Harper Twelvetrees at
the Office of the Commissioners of Patents, with his Petition, on the
22nd August 1862.
I, HARPER TWELVETREES, of Bromley, in the County of Middlesex, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE PREPARATION OF WASHING POWDERS, SOAP POWDERS, AND CLEANSING
CRYSTALS," to be as follows:-
My improvements in, the manufacture of washing and soap powders and
cleansing crystals consist in the introduction of glycerine or extract thereof,
or other oleaginous and fatty matters used in or suitable for the manufacture
of soap in its various branches, into the other ingredients of which the above
powders are composed. The whole of the ingredients when prepared and
mixed in the following proportions, viz., four ounces of glycerine or other
oleaginous matter, three ounces of soda ash, one ounce of borax, one ounce of
carbonate of soda, and half an ounce of carbonate of potassa are to form a
powder, which, with a proper quantity of water to be added, will form a thick

page_text: soap or paste. It is, however, necessary in some cases, according to the
strength and quality of the various ingredients, to vary the proportions of the
component parts in order to attain the desired improvement, which is to
convert all the ingredients into a thick washing soap or paste. I
prepare the
powder for sale either in loose or in casks, boxes, or packets, and if in the latter 5
form I label them with printed labels containing the name of the article on
the face of the packet, and directions for use at the back thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Harper Twelvetrees, in the Great Seal Patent Office on
the 21st February 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HARPER
TWELVETREES, of Bromley, in the County of Middlesex, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of August, 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 sucossors, give and grant unto I, the
said Harper Twelvetrees, Her special licence, that I, the said Harper
Twelvetrees, my executors, administrators, and assigns, or such others as I,
the said Harper Twelvetrees, 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 PREPARATION OF WASHING POWDERS, SOAP POWDERS, AND
CLEANSING CRYSTALS," upon the condition (amongst others) that I, the said
Harper Twelvetrees, 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.
NOW KNOW YE, that I, the said Harper Twelvetrees, 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):-

page_text: My improvement consists in the introduction of glycerine or extract thereof,
or other oleaginous and fatty maters used in or suitable for the manufacture
of soap, into the manufacture of and in combination with washing and soap
powders and cleansing crystals. I usually adopt the following as the proportions
of ingredients in the manufacture of my improved washing and soap powders
and cleansing crystals, viz., four ounces of glycerine or other oleaginous
matter, three ounces of soda ash, one ounce of borax, one ounce of carbonate
of soda, and half an ounce of carbonate of potassa. When the component
parts are properly prepared and mixed in the manner and as well understood
in the manufacture of washing and soap powders, they will form a powder,
which, with a suitable quantity of water to be added, will form a thick soap or
paste. It may be necessary in some cases, according to the strength and
quality of the various ingredients used, to vary the proportions of the component
parts in order to attain the desired result, which is to convert all the ingredients
into a thick washing soap or paste.
Having described the nature of my Invention, and the manner of performing
the same,
I would remark that other ingredients may be substituted for the
soda ash, borax, carbonates of soda and potassa, or added thereto, without
departing from the nature of my Invention, and I declare that what I claim
as my Invention to be protected by the herein-before in part recited Letters
Patent is, combining glycerine or extract thereof, or other oleaginous and
fatty matters, such as are used in or suitable for the manufacture of soap, with
other ingredients or materials in the manufacture of soap powders, washing
powders, and cleansing crystals, as herein-before described.
In witness whereof, I, the said Harper Twelvetrees, have hereunto set
my hand and seal, this Nineteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-three.
