PROVISIONAL SPECIFICATION left by the said George Thomas Jourdain
at the Office of the Commissioners of Patents, with his Petition, on
the 10th June 1862.
I, GEORGE THOMAS JOURDAIN, of St. Paul's Terrace, Canonbury, in the
County of Middlesex, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN TREATING COCOA-NUT OIL," to be as follows:-.
This Invention has for its object improvements in treating cocoa-nut oil.
For these purposes cocoa-nut oil is boiled in water in which is cyanide of
potassium, or of sodium, or of calcium, and such boiling is continued till the
oil is deprived of smell; the whole is then allowed to cool and settle; the
oil is then separated from the matters which settle from it, and washed.,
By these means cocoa-nut oil is rendered more pure and fit for various
purposes.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
THOMAS JOURDAIN, of St. Paul's Terrace, Canonbury, in the County of
Middlesex, send greeting.
WHEREAS Her most. Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of June, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Thomas Jourdain, Her special licence that I, the said George Thomas
Jourdain, my executors, administrators, and assigns, or such others as I, the
said George Thomas Jourdain, 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 TREATING COCOA-NUT OIL," upon the condition (amongst
others) that I, the said George Thomas Jourdain, 'my executors or adminis
trators, by an instrument in writing under my, or their, or onc 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 George Thomas Jourdain, 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:-
This Invention has for its object improvements in treating cocoa-nut oil.
For these purposes cocoa-nut oil is boiled in water in which is cyanide of
potassium, or of sodium, or of calcium, and such boiling is continued till the
oil is deprived of smell; the whole is then allowed to cool and settle; the
oil is then separated from the matters which settle from it, and washed.
By these means cocoa-nut oil is rendered' more pure and fit for various
purposes.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
For each 112 lbs. of cocoa-nut oil, which is to be treated according to my

page_text: Invention, I employ by preference about 4 lbs. of cyanide of potassium,
though other cyanide may, as above mentioned, be used. The cocoa-nut oil
is to be placed in a suitable vessel of wood, together with about 12 gallons of
water for each 112 lbs. of the oil, and the same are to be heated till the oil is
melted, which is conveniently done by free steam introduced through a wooden
pipe perforated with numerous holes, so as to divide the steam into numerous
streams. When the oil is melted the cyanide of potassium is to be thrown in,
and the boiling is to be continued till the cocoa-nut oil is purified to the
desired extent, the contents of the vessel being stirred continually during
the boiling; after which the whole is to be allowed to cool, when the cocoa-
nut oil will separate from the water and impurities.
Any soap which may be formed by the cyanide and the cocoa-nut oil is to
be allowed to cool and separate from the water, and such soap may then be
decomposed by dilute vitriolic acid.
In witness whereof, I, the said George Thomas Jourdain, have hereunto
set my hand and seal, this Sixth day of December, in the year of
our Lord One thousand eight hundred and sixty-two.
G. T. JOURDAIN. (L.S.)
