IMPROVEMENTS IN MAKING OR MANU- 5FACTURING SOAP
Year: 1836

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
LEMAN, of Lincoln's Inn Fields, in the County of Middlesex, Gentleman,
send greeting.
WHEREAS His most Excellent Majesty King William the Fourth, by His
5 Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twelfth day of April, in the sixth year of His reign, did, for
Himself, His heirs and successors, give and grant unto me, the said James
Leman, His special licence that I, the said James Leman, my exors, admors,
and assigns, or such others as I, the said James Leman, my exors, admors,
and 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 within all His Majesty's Colonies
and Plantations abroad, my Invention for "IMPROVEMENTS IN MAKING OR MANU-
5FACTURING SOAP," in which said Letters Patent there is contained a proviso,
obliging me, the said James Leman, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause
the same to be inrolled in His Majesty's High Court of Chancery within six

page_text: calendar months next and immediately after the date of the said recited
Letters Patent.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Leman, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, is described and ascertained
in the manner following, that is to say :-
My improvements in making or manufacturing soap consist of my new
mode of perfecting soap when it is made with cold oil without the use of fire
or boiling, and also of perfecting soap when it is made with concrete oil, fat,
grease, &c., or such matter not in a liquid state, with the use of fire merely
to melt the concrete oil, fat, grease, &c. Those useful results are obtained
by the introduction, in the fabrication of the soap, of chloride or oxymuriate
of lime, of soda, or of potash.
100 ditto
ditto
45 ditto
ditto
of solution of chloride or oxymuriate of lime,
filtered and very clear, of a specific gravity
of 1,047, to 1,064.
of ley of caustic soda, of a specific gravity of
1,333.
Begin the operation by pouring the solution of chloride of lime upon the
oil in small quantities, at the same time taking care to stir and beat them
continually well together during the operation; after having poured the
solution of chloride of lime, then pour the ley of caustic soda in the same
manner, always taking the same care to stir it well; the act of the pouring
must be done very slowly, for the mixture must not be made quickly. The soap
being thus compounded, pour it into the moulds, and at the end of three days
it will be of a suitable consistency. When the concrete oil, fat, grease, &c.
are used, melt it in a water bath, taking great care not to make use of more
heat than is necessary merely to melt it, then operate as before explained.
To make the soap by employing the chloride or oxymuriate of soda, take,—
108 parts by measure of oil.
110 ditto
ditto
36 ditto
ditto
of solution of chloride of soda, of a specific
gravity of 1,089.
of ley of caustic soda, of a specific gravity of
1,333.

page_text: the chloride or oxymuriate of potash may be used in the same manner and in
the same proportions as the solution of chloride of soda.
In witness whereof, I, the said James Leman, have hereunto set iny
hand and seal, this Eleventh day of October, in the year of our
Lord One thousand eight hundred and thirty-six.
Signed, sealed, and delivered by the
within-named James Leman, in
the presence of
J. F. BERNARD, his Clerks.
JAMES (L.S.) LEMAN.

tenor of the Statute made for that purpose.
Inrolled the Twelfth day of October, in the year of our Lord One
thousand eight hundred and thirty-six.
