AN IMPROVE- MENT IN THE MANUFACTURE OF SOAP
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
LLOYD CALDECOT, of 6, Laura Place, in the City of Bath, Esquire, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventeenth day of March, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Lloyd Caldecot, my exors, admors, and assigns, Her especial license,
full power, sole privilege, and authority, that I, the said William Lloyd
Caldecot, my exors, admors, and assigns, or such others, as I, the said William
Lloyd Caldecot, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, and also in all
Her said Majesty's Colonies and Plantations abroad, and in the Islands of
Jersey, Guernsey, Alderney, Sark, and Man, my Invention of "AN IMPROVE-
MENT IN THE MANUFACTURE OF SOAP;" in which said Letters Patent is
contained a proviso, that I, the said William Lloyd Caldecot, shall particularly
describe and ascertain the nature of my said Invention, and in what mauner

page_text: the same is to be performed, by an instrument in writing under my hand and
seal, and cause the same to be inrolled in Her said Majesty's High Court of
Chancery, within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Lloyd Caldecot, do hereby declare that the nature of my Inven-
tion, and the manner in which the same, is to be performed, are. particularly
described and ascertained in and by the following statement thereof, that is to
say:-
My Invention consists of combining Barbadoes' tar with soap, so as to pro-
duce a new manufacture of soap. And the Invention also consists in com-
bining other bituminous substances with soap, such as petroleum and other
varieties of natural naphtha. And in order that my Invention may be most
fully understood and readily carried into effect, I will proceed to describe the
means pursued by me; I prefer to use. tar generally known in commerce as
Barbadoes tar, such tar being obtained from the surface of some springs and
wells of water arising on an estate called Mount Hall, as well as on other estates
in the Parishes of Saint Andrew and Saint Joseph in the Island of Barbadoes.
The compounded soap thus produced when in use is such that, the soap alone
retains its solvent powers in water; the Barbadoes tar or other bituminous
substance remains insoluble and floats on the surface of the water; and hence
in cutaneous eruptions, the soap in solution detaches any foreign matter from
the skin, and thus prepares the skin for the subsequent deposit of the tar, by
which its curative powers are brought into action; the peculiar properties of
the compound soap prevent that unpleasant irritation so often experienced
from the employment of ordinary soap. The Barbadoes tar or other bitu-
minous substances is combined with soap after the same has been made, in the
ordinary manner, and when the same is of about a temperature, a little below
that of boiling water, or 212° of Fahrenheit; and the proportion in which I
combine the tar with soap is about fifteen per cent. of the tar in weight of the
soap, and they are, combined by stirring till the whole are intimately mixed.
The soap is to be formed of the best materials, and should consist of the best
tallow, with its requisite proportions, of alkali to form the saponaceous mass,
and when properly united then to add any or either of the above-named
bituminous substances, but by preference. Barbadoes tar, otherwise called Bar-
badoes naphtha, from the natural springs of Barbadoes, as before mentioned.
Having thus described the nature of my Invention, and the best means I

page_text: am acquainted with for performing the same, I would have it understood that
what I claim is the combining Barbadoes tar or other variety of natural
naphtha with soap, as herein described.
In witness whereof, I, the said William Lloyd Caldecot, have hereunto
set my hand and seal, this Thirty-first day of July, in the year of our
Lord One thousand eight hundred and forty-five.
WILLIAM LLOYD CALDECOT. (L.s.)
AND BE IT REMEMBERED, that on the Thirty-first day of July, in the
year of our Lord 1845, the aforesaid William Lloyd Caldecot came before
our said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
