Sealed the 3rd September 1860, and dated the 5th March 1860.
PROVISIONAL SPECIFICATION left by the said Joseph Broel at the Office
of the Commissioners of Patents, with his Petition, on the 5th March
1860.
I, JOSEPH BROEL, of Manchester, in the County of Lancaster, Merchant,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN THE MANUFACTURE OF SOAP," (a communication from abroad by A. B.
Devine, of New York, U.S.A.,) to be as follows:-
This improvement consists in an alteration of the process in the manu-
facture of soap, whereby considerable economy is effected both in time, labor,
and fuel, and also further saving is effected, inasmuch as there is little or no
waste of the lyes. The improvement is effected by blending or bringing
together the different materials employed whilst in a boiling state, and in such
quantities as to form soap. at once, in contradistinction to the methods
employed at present in "soap boiling" in the manufacture of common yellow
soap, which may be made either with tallow or palm oil. I take about one
hundred and seventy-four pounds of tallow or palm oil, and ninety-six pounds
of rosin; next I take about twenty-four pounds of water, and boil it with
about thirty pounds of such lime as contains seventy per cent. of carbonic acid
gas, and which has been previously thoroughly slacked, and when sufficiently
so pour in water to make in all four hundred and thirty-two pounds; then

page_text: add one hundred and ninety-six pounds of soda, and allow it to dissolve,
stir these together, and pour the lay so made through a sieve (of about eighty
meshes to an inch), and allow it to fall into the vessel of tallow and resin,
continually stirring them together, when it will at once form itself into soap.
Although the process is here described for the manufacture of "yellow soap,"
yet, with slight alterations in the ingredients, it is equally applicable to all
other descriptions of soap. ·
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Broel in the Great Seal Patent Office on the
5th September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BROEL,. of Manchester, in the County of Lancaster, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year. of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Broel, Her special license that I, the said Joseph Broel, my
executors, administrators, and assigns, or such others as I, the said Joseph
Broel, 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 "CERTAIN, IMPROVEMENTS, IN THE
MANUFACTURE OF SOAP," upon the condition, amongst others, that I, the said
Joseph Broel, by an instrument in writing under my hand and seal, . 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Broel, 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) :-
This improvement consists in an alteration of the process in the manu
facture of soap, whereby considerable economy is effected both.in time, labor,
and fuel, and also further saving is effected, inasmuch as there is little or no

page_text: waste of the lyes. The improvement is effected by blending or bringing
together the different materials employed, whilst in a boiling state, and in such
quantities so as to form soap at once, in contradistinction to the methods
employed at present in "soap-boiling." In the manufacture of common yellow
Soap (for example), which may be made either with tallow, common fat, or
palm oil, or cocoa-nut oil, with the addition of resin, I take about 174 lbs. of
tallow or other fats, and about 96 lbs. of resin; next I take about 24 lbs. of
water, and boil it, and slack therein about 30 lbs. of fine lime, and when
sufficiently so, pour in water to make in all about 400 lbs. or less, then add
196 lbs. of soda, and allow it to dissolve, stir together, boil up well, and pour
the solution or lye so made through a seive (of about 80 meshes to an inch),
in order to keep back the sediment of the line, and allow it to fall into the
vessel of tallow and resin, continually stirring them together, when it will
form itself into soap; allow this soap to cool, and when so boil it up again, so
as to bring it again into a liquid state, when it will be ready to pour into the
"soap frames," and allow it to cool. If it is desired to make the soap dry
quicker, I use less water, say from 250 to 350 lbs. of water to the above-
named quantities. Although the process is here described for the manu-
facture of "yellow soap," yet, with slight alteration in the ingredients, it is
equally applicable to all descriptions of soap.
For white curd soap I take 270 lbs. of tallow, or for a better quality
I employ 300 lbs. of tallow, to which, when melted, I add the lye prepared of
30 lbs. of fine lime, about 190 lbs. of soda, and about 300 to 350 lbs. of water.
This soap allowed to cool and then heated again to the liquid state, and
poured into the "forms," will yield when dry a clear and hard quaity of
washing soap.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I would remark, in con-
clusion, that I claim blending together the several materials employed in a
boiling state, and in such quantities as to form soap at once, in contra-
distinction to other methods at present in use.
In witness whereof, I, the said Joseph Broel, have hereunto set my
hand and seal, this Fourth day of September, in the year of our Lord
One thousand eight hundred and sixty.
JOS. BROEL. (L.S.)
