Chemist, for the Invention of "AN IMPROVED DISINFECTANT AND
DEODORISER."
Sealed the 12th April 1872, and dated the 18th October 1871.
PROVISIONAL SPECIFICATION left by the said William Crookes at the
Office of the Commissioners of Patents, with his Petition, on the
18th October 1871.
I, WILLIAM CROOKES, of the City of London, Scientific Chemist, do
hereby declare the nature of the said Invention for "AN IMPROVED
DISINFECTANT AND DEODORISER,” to be as follows:-
My Invention consists in mixing together or passing sulphurous acid
gas to saturation into carbolic acid, or the liquid commercially known
as carbolic acid, which consists of carbolic and cresylic acids, and similar
homologues of carbolic acids, to produce a compound or compounds
possessing disinfecting, deodorising, and antiseptic properties, of a nature
superior to those of the constituents when employed separately.

page_text: Another part of my Invention consists in the use of the liquid com-
mercially known as creosoto, or any mixtures of carbolic, cresylic, and
homologous acids and creosote in lieu of carbolic acid,
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Crookes in the Great Seal Patent Office
on the 16th April 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CROOKES, of the City of London, Scientific Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of October, in the 1
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Crookes, Her special license
that I, the said William Crookes, my executors, administrators, and
assigns, or such others as I, the said William Crookes, 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 DIS-1
INFECTANT AND DEODORISER," upon the condition (amongst others) that I, the
said William Crookes, 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 William Crookes, 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 Invention consists in mixing together or passing sulphurous acid
into carbolic acid to produce a compound or compounds possessing.

page_text: disinfecting, deodorising, and antiseptic properties of a nature superior
to those of the constituents when employed separately.
Another part of my Invention consists in the use of cresylic acid or
other similar homologue of carbolic acid or the liquid commercially
known as creosote or any mixtures of the above in lieu of carbolic acid.
Having thus stated the nature of my Invention I wish it to be
understood that I do not limit myself to any definite proportion of the
ingredients referred to, as the same must be varied according to the
peculiar purpose for which the improved disinfectant or deodoriser is
intended to be applied.
י
I claim first, the mixing together or passing sulphurous acid into
carbolic acid for the purposes described, and, secondly, the mixing
together or passing sulphurous acid into cresylic acid, or the liquid
commercially known as creosote, or any mixtures of the same.
In witness whereof, I, the said William Crookes, have hereto
set my hand and seal, this Thirteenth day of April One thousand
eight hundred and seventy-two.
