PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on. the
22nd July 1864.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No.. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN IMPROVED
PROCESS OR MEANS OF DECONGELATING OILS," (a communication to me from
abroad by Eugène Bernard and Eugène Perrin, both of No. 39, Faubourg
St. Martin, Paris, France, to be as follows:-
Without entering into the several chemical and physical causes which
occasion the congelation of oils, it may suffice to state that several incon.
veniences result from this state of solidification, and that the attention of
persons dealing with oils, more especially railway companies, which use oil

page_text: largely for lighting purposes, has long been directed to the discovery of a
means which will permit the use of these oils in a medium state when the
temperature is low enough to cause their congelation or thickening, but not-
withstanding all their efforts and researches this problem remained to be solved.
By this Invention it is proposed to preserve lighting oils in a liquid state
at the very low temperatures to which they are sometimes exposed by the
addition of certain agents in proportions varying with the nature of the oil.
'These agents are no other than "luciline" and "nut oil," used in proportions
which cannot be determined; but it is important to observe that far from
injuring the illuminating qualities of the oils, they add to them. These pro-
cesses apply to lubricating oils with as much success as to those used for
lighting, with this difference, that "luciline" only should be used, as the nut
oil would facilitate the formation of gome. In this case the decongelation
cannot be effected at so low a temperature as for the oils used for lighting,
nevertheless it has been effected at six degrees below zero.
To sum up, this Invention consists in the decongelation of oils of every
.description, no matter of what nature or from whence derived, by the appli-
cation of "luciline" and nut oil in combination, as well as the decongelation
by the addition of one of these two substances used singly; and as already
stated no quantities can be determined, as they depend entirely upon the
nature of the oil and the temperature at which the operation is effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Gedge in the Great Seal Patent Office
on the 20th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11, Wellington
Street, Strand, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of July, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Edward Gedge, Her special licence that I, the
said William Edward Gedge, my executors, administrators, and assigns, or
such others as I, the said William Edward Gedge, my executors, adminis-
trators, 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,

page_text: 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 "AN IMPROVED PROCESS OR MEANS OF DECONGELATING OILS,"
(a communication to me. from abroad by Eugène Bernard and Eugène Perrin,
both of No. 39, Faubourg St. Martin, Paris, France,) upon the condition
(amongst others) that I, the said William Edward Gedge, my executors 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 William Edward Gedge, do hereby
declare the nature of the said Invention, and in what manner the same was
to be performed, to be particularly described and ascertained in and by the
following statement:-
Without entering into the several chemical or physical causes which
occasion the congelation of oils, it may suffice to state that several inconve-
niences result from this state of solidification, and that the attention of persons
dealing with oils, more especially railway companies, which use oils largely for
lighting purposes, has long been directed to the discovery of a means which
will permit the use of these oils in a medium state when the temperature is
low enough to cause their congelation or thickening, but notwithstanding all
their efforts and researches this problem remained to be solved.
The means used under this Invention to preserve lighting oils in a liquid
state at the very low temperatures to which they are sometimes exposed is
based upon the addition of certain agents, in proportions varying with the
nature of the oil. These agents are no other than "luciline" and "nut oil," used
in proportions which cannot be determined; but it is important to observe
that far from injuring the illuminating qualities of the oils, they add to them.
This process applies to lubricating oils with as much success as to those used
for lighting, with this difference, that "luciline" only should be used, as the
"nut oil" would facilitate the formation of gome. In this case the deconge-
lation cannot be effected at so low a temperature as for the oils used for
lighting, nevertheless it has been effected at six degrees below zero.
To sum up, this Invention consists in the decongelation of oils of every
description, no matter of what nature or whence derived, by the application
of "luciline" and "nut oil" in combination, as well as the decongelation of
the addition of one of these two substances used singly; and as already stated

page_text: no quantities can be determined as they depend entirely upon the nature of
the oil and the temperature at which the operation is effected.
In witness whereof, I, the said William Edward Gedge, have hereunto
set my hand and seal, this Twentieth day of January, in the year of
our Lord One thousand eight hundred and sixty-five.
