Year: 1870

page_text: LETTERS PATENT to Spendlove Desborough, of Owen's Row, Clerk-
enwell, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF SOAP, AND IN CHEMICAL COMPOUNDS
APPLICABLE TO THE CURE OF SKIN DISEASES."
Sealed the 23rd May 1871, and dated the 25th November 1870.
PROVISIONAL SPECIFICATION left by the said Spendlove Desborough
at the Office of the Commissioners of Patents, with his Petition, on
the 25th November 1870.
I, SPENDLOVE DESBOROUGH, of Owen's Bow, Clerkenwell, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF SOAP, AND IN CHEMICAL COMPOUNDS
APPLICABLE TO THE CURE OF SKIN DISEASES," to be as follows:—
The first part of my Invention relates to the manufacture of a superior
quality of soap from ordinary common yellow or other inferior soap,
by the addition thereto of hyposulphite of soda and water, whereby a
soap of superior quality and colour is produced, and at less cost than
the ordinary yellow or other inferior soap, from which it is. chiefly
manufactured.

page_text: For this purpose in manufacturing soap in accordance with my
Invention I dissolve twenty-eight pounds, or thereabout, of hyposul-
phite of soda in about four gallons of boiling water, to which I add
about two hundredweight and a half of ordinary soap of commerce, the
whole being melted in a suitable vessel and boiled for about an hour,
after which it is run into frames to cool, and cut up in the ordinary
manner, as is well understood in the manufacture of soap. The frames
are furnished with a strainer at the bottom for drawing off any surplus
water.
Ordinary soft soap may be treated in accordance with my Invention;
equal parts by weight of hyposulphite of soda dissolved. in its own
weight of water, being added to and combined with the same weight
of soft soap, melted as previously described, the quantity of hypo-
sulphite employed depending upon the nature of the soft soap to be
treated. A sweet and hard soap is thus manufactured at a greatly
reduced cost.
In place of remelting and treating manufactured soap as previously
described in accordance with my Invention, and description of soap
may be treated according to my Invention in the first process of
manufacturing the same by the addition of a solution of hyposulphite
of soda thereto in suitable quantities according to the nature of the
soap, in order to improve the quality and reduce the cost of soap so
manufactured.
In order to manufacture fancy soap in accordance with my Invention
I add coloring matter and scent in suitable quantities when the soap is
in a melted state and treated as previously described.
In order to manufacture medicated soap in accordance with my
Invention for the treatment and cure of skin and other diseases I add
to soap (prepared and treated as previously described according to the
first part of my. Invention or otherwise) whilst in a melted state about
half an ounce of iodine dissolved in about one ounce of solution of
hyposulphite of soda to every pound of soap.. After being thoroughly
incorporated with the soap it is run into frames to cool and be cut and
made up for sale in the ordinary manner.
The combination of iodine with hyposulphite of soda dissolved in a
water, as previously: described, may be employed in accordance with
another part of my Invention for the treatment and cure of skin diseases
without the addition of soap, the discolouring of the skin by the use of

filed by the said Spendlove Desborough in the Great Seal Patent
Office on the 24th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SPENDLOVE
DESBOROUGH, of Owen's Row, Clerkenwell, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-fifth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Spendlove Desborough, Her special licence
that I, the said Spendlove Desborough, my executors, administrators, and
assigns, or such others as I, the said Spendlove Desborough, my exe-
cutors, 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 SOAP, AND IN CHEMICAL COMPOUNDS APPLICABLE TO THE
CURE OF SKIN DISEASES," upon the condition (amongst others) that I, the
said Spendlove Desborough, 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 Spendlove Desborough, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
The first part of my Invention relates to the manufacture of a superior
quality of soap from ordinary common yellow or other inferior soap,

page_text: by the addition thereto of hyposulphite of soda and water, whereby
a soap of superior quality and colour is produced, and at less cost
than the ordinary yellow or other inferior soap, from which it is chiefly
manufactured..
For this purpose in manufacturing soap in accordance with my
Invention I dissolve twenty-eight pounds, or thereabouts, of hypo-
sulphite of soda in about four gallons of boiling water, to which I add
about two hundredweight and a half of ordinary soap of commerce, the
whole being melted in a suitable vessel and boiled for about an hour,
after which it is run into frames to cool and cut up in the ordinary
manner, as is well understood in the manufacture of soap. The framers
are furnished with a strainer at the bottom for drawing off any surplus
water.
Ordinary soft soap may be treated in accordance with my Invention;
equal parts by weight, or thereabouts, of hyposulphite of soda dissolved
in its own weight of water being added to and combined with the same.
weight of soft soap melted, as previously described, the quantity of hypo-
sulphite of soda employed depending upon the nature of the soft soap
to be treated, inferior or adulterated qualities of soft soap absorbing less
hyposulphite than the better qualities. A sweet and hard soap is thus
manufactured at a greatly reduced cost.
In place of remelting and treating manufactured soap, as previously
described, in accordance with my Invention, any description of soap
may be treated according to my Invention in the first process of
manufacturing the same by the addition of a solution of hyposulphite
of soda thereto in suitable quantities, according to the nature of the
soap, in order to improve the quality and reduce the cost of soap so
manufactured. The solution of hyposulphite of soda may be added in
such quantities during the process of manufacture in accordance with
the judgment of the maker in order to obtain the quality and color of
the soap required.
In order to manufacture fancy soap in accordance with my Invention
I add coloring matter and scent (the latter after ebullition has ceased)
in suitable quantities when the soap is in a melted state, and treated
or combined with hyposulphite of soda, as previously described.
In order to manufacture medicated soap in accordance with my
Invention for the treatment and cure of skin and other diseases I add
to soap (prepared and treated as previously described, according to the

page_text: first part of my Invention, or otherwise) whilst in a melted state about
half an ounce of iodine dissolved in about one ounce of solution of hypo-
sulphite of soda to every pound of soap. After being thoroughly incor-
porated with the soap it is run into frames to cool and be cut and made
up for sale in the ordinary manner.
The combination of iodine with hyposulphite of soda dissolved in
water, as previously described, may be employed in accordance with
another part of my Invention for the treatment and cure of skin diseases
without the addition of soap, the discoloring of the skin by the use of
iodine alone being prevented by its admixture with the solution of hypo-
sulphite of soda.
The preparation of iodine and hyposulphite of soda is simply applied
to the parts affected by a brush or otherwise.
Having thus described the nature of my Invention, and the manner
of carrying the same into practice, what I claim is,--
First. The manufacture of an improved quality of soap by the
combination of hyposulphite of soda therewith, as herein described.
Secondly. I claim the manufacture of medicated soap by combining
iodine dissolved in hyposulphite of soda with melted soap, as herein
described.
Thirdly. I claim the use and application of iodine dissolved in a
solution of hyposulphite of soda for the treatment and cure of skin
diseases, as herein described.
In witness whereof, I, the said Spendlove Desborough, have here-
unto set my hand and seal, this Twenty-third day of May, in the
year of our Lord One thousand eight hundred and seventy-one.
