IMPROVEMENTS IN THE MANUFACTURE OF PROVISIONAL SPECIFICATION
Year: 1866

page_text: LETTERS PATENT to John Hooker, of Walton-on-Thames, in the County'
of Surrey, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
PROVISIONAL SPECIFICATION left by the said John Hooker at the Office
of the Commissioners of Patents, with his Petition, on the 15th January
1866.
I, JOHN HOOKER, of Walton-on-Thames, in the County of Surrey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF AMMONIACAL AND AMMONIATED SOAP," to be as follows:-
I treat ammoniacal common or other soap with ammonia in excess, or I add
an ammoniacal or ammoniated salt to soap, which salt will give off ammonia
when the soap is used (a salt or base to be added if necessary in order to free
the ammonia, such as lime potash). I propose also to cover the soap so
made with a case of suitable soap or washing compound or soluble or other
substance which would prevent the ammonia escaping until such time as
the soap is required for washing purposes, but which would not interfere with
the detergent properties of the soap. The case may be made in many ways,
two of which may be mentioned; first, to cast the substance used in a mould,
and fill in the ammoniacal soap, afterwards plugging the case with the same

page_text: material used for the case; secondly, by boring a hole in a bar of soap, which
hole is then to be filled with my improved soap and closed by a plug of the
same material as the outer casing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hooker in the Great Seal Patent Office on the 14th
July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HOOKER,
of Walton-on-Thames, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-six, and in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Hooker, Her special licence that I, the said John Hooker,
my executors, administrators, and assigns, or such others as I, the said John
Hooker, 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 MANUFACTURE
OF AMMONIACAL AND AMMONIATED SOAP," upon the condition (amongst others)
that I, the said John Hooker, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 John Hooker, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
.
I treat ammoniacal common or other soap with ammonia in excess, or I
add an ammoniacal or ammoniated salt to soap, which salt will give off
ammonia when the soap is used, (a salt or base to be added if necessary in
order to free the ammonia), such as lime potash. I propose also to cover
the soap so made with a case of suitable soap or washing compound or
soluble or other substance, so as to prevent the ammonia escaping until such

page_text: time as the soap is required for washing purposes, but which would not
interfere with the detergent properties of the soap. The case may be made
in many ways, two of which may be mentioned; first, to cast the substance
used in a mould and fill in the ammoniacal soap, afterwards plugging the case
with the same material used for the case; secondly, by boring a hole in a bar of
soap, which hole is then to be filled with my improved soap and closed by a plug
of the same material as the outer casing.
In witness whereof, I, the said John Hooker, have hereunto set my hand
and seal, this 14th day of July, in the year of our Lord One thousand
eight hundred and sixty-six.
JOHN HOOKER. (L.B.)
