Place, Holborn, in the County of Middlesex, Civil Engineer, for
the Invention of "IMPROVEMENTS IN SOLID AND LIQUID DISINFECTANTS
AND DEODORIZERS."
Sealed the 9th July 1875, and dated the 10th February 1875.
PROVISIONAL SPECIFICATION left by the said Harry Langston Jones
at the Office of the Commissioners of Patents, with his Petition,
on the 10th February 1875.
I, HARRY LANGSTON JONES, of Webster's Hotel, Ely Place, Holborn,
in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN SOLID AND LIQUID
DISINFECTANTS AND DEODORIZERS," to be as follows:-
:-
This Invention relates to disinfecting powders and solutions, and
consists in a combination or mixture of mineral sulphates and chloroides
of the earthy, salts, especially the combination of sulphate of zinc or
sulphate of iron, with chloride of sodium or of calcium.
The salts are powdered and mixed in the proportions of 10 per cent.
of sulphate of zinc to 90 per cent. of chloride of calcium.
For liquid disinfectants this same powder is dissolved in water in the

filed by the said Harry Langston Jones in the Great Seal Patent
Office on the 16th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HARRY
LANGSTON JONES, of Webster's Hotel, Ely Place, Holborn, in the County)
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of February, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Harry Langston Jones, Her special
licence that I, the said Harry Langston Jones, my executors, admi-
nistrators, and assigns, or such others as I, the said Harry Langston
Jones, my executors, administrators, and assigns, should at any time
agrco with, and no others, from time to time and at all times there.
after 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 Inven-
tion for "IMPROVEMENTS IN SOLID AND LIQUID DISINFECTANTS AND DEODORIZERS,"
upon the condition (amongst others) that I, the said Harry Langston
Jones, 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 Harry Langston Jones, 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:-
The object of this Invention is to produce cheap and efficient disinfec-
tants and deodorizers either in a solid or liquid form. With this view I
employ a mixture or combination of mineral sulphates with chlorides of

page_text: the earthy salts, especially the combination of sulphate of zinc or sulphate
of iron, with chloride of sodium or of calcium.
I either make use of a mixture consisting of sulphate of zinc and
chloride of calcium in the proportions of from 10 per cent of the sulphate
of zinc to 90 per cent. of the chloride of calcium, or the mixture I most
generally employ is one composed of sulphate of zinc, chloride of
calcium, and chloride of sodium, the proportions of which in 100 parts
are as follow:-Chloride of calcium, 20 parts; chloride of sodium, 50
parts; sulphate of zinc, 30 parts = 100 parts. This powder is granulated
and intimately mixed, and the compound powder thus formed then by
chemical reaction consists of mixed chlorides of zinc and sulphates of
sodium and calcium.
This mixture or combination of the mineral sulphates with the
chlorides of the earthy salts may be employed in a solid form, or a
solution thereof used in the proportions of 1 pound of the powder to
every gallon of water. The degree of strength may be varied according
to desire, or a saturated solution used for disinfecting and deodorizing
purposes, and by the addition of a little blue aniline the liquid may be
coloured. The essence of the Invention therefore consists in the mixture
of the mineral sulphates with the chlorides of the earthy salts in the
proportions specified, which when combined undergo and effect a mutual
decomposition, and thus acquire valuable qualities for the purposes of
cheap and efficient disinfectants and deodorizers.
I claim the compound powder herein described for use either in a
solid form, or as a solution in the manner and for the purposes herein
specified.
In witness whereof, I, the said Harry Langston Jones, have here-
unto set my hand and seal, this Thirteenth day of July, in the
Heer of our Lord One thousand eight hundred and seventy-five.
