Year: 1873

page_text: LETTERS PATENT to Richard Gibbon, of Warwick House, Maidstone,
in the County of Kent, for the Invention of "AN IMPROVED Manu-
FACTURE OF SOAP."
Sealed the 17th February 1874, and dated the 21st August 1873..
PROVISIONAL SPECIFICATION left by the said Richard Gibbon at the
Office of the Commissioners of Patents, with his Petition, on the
21st August 1873..
I, RICHARD GIBBON, of Warwick House, Maidstone, in the County of¨*
Kent, do hereby declare the nature of the said Invention for "AN IM-
PROVED MANUFACTURE OF Soap,” to be as follows:—
The object of the Invention is the manufacture of soap having
increased cleansing properties, by which it is especially adapted to
laundry and such like uses..
In the manufacture of soap according to my Invention before the.
process of boiling is complete, but after all the ordinary ingredients have
been supplied to it, I add thereto some of the best imperial or other
blue, which has first been thoroughly dissolved or reduced to fine

page_text: powder, and I combine the whole by thorough mixing. The proportion
of blue added will vary. with the quality or character of the bluc used,
but when employing the best imperial blue I find a proportion of it of,
say, one-tenth by weight of the whole mass to answer well, but I do pot
confine myself to that proportion. The compound obtained is then cut
into bars or formed into blocks for use, as may be desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Gibbon in the Great Scal Patent Office
on the 18th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
GIBBON, of Warwick House, Maidstonc, in the County of Kent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of August, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Richard Gibbon, Her
special license that I, the said Richard Gibbon, my executors, admi-
nistrators, and assigns, or such others as I, the said Richard Gibbon,
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 MANUFACTURE OF SOAP," upon the condition (amongst others)
that I, the said Richard Gibbon, 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 Richard Gibbon, do hereby
declare the nature of the said Invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
The object of the Invention is the manufacture of soap having
increased cleansing and beautifying properties, by which it is especially
adapted to laundry and such like uses.
In the manufacture of soap according to my Invention before the
process of boiling is complete, but after all the ordinary ingredients for
the manufacture of soap of the ordinary commercial character have been
supplied to it, I add thereto some of Reckitt & Son's best Paris or
other suitable blue, which has first been thoroughly dissolved or reduced
to fine powder, and I combine the whole by thorough mixing.. The
proportion of blue added will vary with the quality or character of it.
used, but when employing Reckitt & Son's best Paris blue I find a
proportion of it, of say, one-tenth by weight of the whole mass to answer
well, but I do not confine myself to that proportion. The compound
obtained is a perfect blue solid soap, and is then cut into bars or formed
into blocks for use, as may be desired.
Having thus described my Invention I would have it understood I
am aware that in the manufacture of a very low class of cheap soap
china, clay, common kitchen stuff, lime, chalk, sulphur, soda, tallow,
and other materials are mixed together in the copper, and a small
quantity of ultramarine blue is then introduced and mixed with such
ingredients to hide the adulteration thereof, and give a somewhat
mottled appearance to the soap obtained, but with no beneficial object
or effect adapted in any way to make the soap a better cleansing agent,
I do not therefore claim the use of the blue coloring matter so employed,
but what I do claim is, the manufacture of a solid blue soap in which
Paris or other suitable blue is incorporated in manner and for the
purpose substantially as stated.
In witness whereof, I, the said Richard Gibbon, have hereunto set
my hand and seal, this Sixteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-four.
