Year: 1866

page_text: LETTERS PATENT to Scipion Sequelin, of Deptford, in the County of
Kent, Chemist, for the Invention of "IMPROVEMENTS IN THE PURIFICATION,
CLARIFICATION, AND PREPARATION OF ANIMAL AND VEGETABLE WAX, TALLOW,
OILS, AND OTHER SIMILAR WAXY AND FATTY SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Scipion Sequelin at the
Office of the Commissioners of Patents, with his Petition, on the 26th
April 1866.
I, SCIPION SEQUELIN, of Deptford, in the County of Kent, Chemist, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
PURIFICATION, CLARIFICATION, AND PREPARATION OF ANIMAL AND VEGETABLE WAX,
TALLOW, OILS, AND OTHER SIMILAR WAXY AND FATTY SUBSTANCES," to be as
follows:-
This Invention is designed for the purpose of purifying, clarifying, and
preparing wax, tallow, oils, and other waxy and fatty substances for illu-
minating and other purposes.
I first melt the wax or fatty substance in a vessel or apparatus heated by
means of a hot water bath (or by steam), and raise the temperature to about
one hundred and eighty degrees Fahrenheit; I then add to each one hundred
pounds of the same about one ounce and a quarter of isinglass (using by
preference the Russian isinglass cut very fine), which will have the effect of
causing the precipitation of all the impurities to the bottom of the vessel; and
after allowing it to remain and settle in the vessel or apparatus for about

page_text: thirty hours (keeping it liquid by a heat of about one hundred and seventy
degrees Fahrenheit); I then run the solid fatty substances into moulds, and
the liquid fatty substances into casks or other vessels, and the operation is
finished.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Scipion Sequelin in the Great Seal Patent Office on the
26th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SCIPION
SEQUELIN, of Deptford, in the County of Kent, Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Scipion Sequelin, Her special licence that I, the said Scipion
Sequelin, my executors, administrators, and assigns, or such others as I, the
said Scipion Sequelin, 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 "IM-
PROVEMENTS IN THE PURIFICATION, CLARIFICATION, AND PREPARATION OF ANIMAL AND
VEGETABLE WAX, TALLOW, OILS, AND OTHER SIMILAR WAXY AND FATTY SUB-
STANCES," upon the condition (amongst others) that I, the said Scipion
Sequelin, my exccutors 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 Scipion Sequelin, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, that is to say:―
This Invention is designed for the purpose of purifying, clarifying, and
preparing wax, tallow, oils, and other waxy and fatty substances for illu-
mination, lubrication, dressing wool, and other purposes.

page_text: In treating solid waxy or fatty substances I first melt such waxy or fatty
substances in a suitable vessel or apparatus by means of a hot water bath (or
by steam), and I raise the temperature to about one hundred and eighty
degrees Fahrenheit; I then add to each hundred pounds of the same about
one ounce and a quarter of isinglass (using by preference the Russian
isinglass cut very fine), which will have the effect of causing the precipitation
of all the impurities to the bottom of the vessel, and after allowing it to
remain and settle in the vessel or apparatus for about thirty hours (keeping it
liquid by a constant heat of about one hundred and sixty to one hundred and
seventy degrees Fahrenheit); I then run the purified waxy or fatty substance
into moulds, where it cools and solidifies, and it is then ready for use.
In treating oils or other liquid fatty substances I proceed in the same way
by the employment of isinglass in the same proportion, either with or without
the application of heat, excepting that they of course being already liquid do
not require melting in the first instance, nor yet keeping in a liquid state by
means of heat during the settling or precipitation of the impurities, and instead
of running them off (when purified) into moulds I run them into casks or
other vessels suitable for containing liquids, and they are then ready for use.
Having now described the nature and object of my said Invention for
Improvements in the Purification, Clarification, and Preparation of Animal.
and Vegetable Wax, Tallow, Oils, and other similar Waxy and Fatty Sub-
stances," together with the manner in which the same is to be or may be
performed or carried into practical effect, I would remark in conclusion that
I claim as my Invention the treatment of waxy or fatty substances by means
of isinglass in combination with heat, substantially in the manner and for the
purposes herein-before particularly set forth.
In witness whereof, I, the said Scipion Sequelin, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
