Year: 1853

page_text: LETTERS PATENT to Jean Emile Barse, Chemist, of Paris, in the
French Empire, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF GREASE OR COMPOSITION FOR LUBRICATING THE AXLES
AND MOVING PARTS OR MAQUINED"
PROVISIONAL SPECIFICATION left by the said Jean Emile Barse
at the Office of the Commissioners of Patents, with his Petition,
on the 16th May 1853.
I, JEAN EMILE BARSE (Chemist), of Paris, in the French Empire,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF GREASE OR COMPOSITION FOR LUBRICATING THE
AXLES AND MOVING PARTS OF MACHINERY" to be as follows:-
My Invention consists of combining with mercury fatty or unctuous
matters, such as the following:-Hog's lard, ricini or castor oil, and
soft soap, prepared from whale oil, by acting on it with metallic oxides
or alkalies.
The proportions in which I mix these substances vary according to

page_text: the use to which the composition is to be applied, but I find the
following to be generally useful-Mercury, 1 part; hog's lard, 24 parts;
ricini or castor oil, 6 parts; soft soap, 10 parts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jean Enile Barse in the Great Seal Patent
Office, on the 14th November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I
JEAN EMILE BARSE (Chemist), of Paris, in the French Empire, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing late the Sixteenth day of May, in the year of
our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jean Einile Barse, Her special
licence that I, the said Jean Emile Barse, my executors, adminis-
trators, and assigns, or such others as I, the said Jean Emile Barsc,
iny 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,
uso, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF GREASE OR COMPOSITION FOR
LUBRICATING THE AXLES AND MOVING PARTS OF MACHINERY," upon the
condition (amongst others) that T, the said Jean Emile Barse, by an in-
strument 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 Scal Patent Office within six calendar months next and imme-
liately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jean Emile Barse, 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):

page_text: My Invention consists of combining with mercury fat or unctuous
matters, such as the following:-Hogs lard, ricine or castor oil, and
soft soap, prepared from whale oil, by acting on it with metallic oxide
or alkalies.
The proportions in which I mix these substances vary according to
the use to which the composition is to be applied, but I find the
following to be generally useful:-Mercury, 1 part; hogs lard, 24 parts;
ricine or castor oil, 6 parts; soft soap, 10 parts.
And in order that my Invention may be most fully understood, and
readily carried into effect, I will proceed to describe the manner in
which I prepare the composition. I add the mercury (which I profer
to use in the form of protoxide), or as it is sometimes called (Ethiops
per se), to a portion of the hogs lard, and incorporate them by trituration
in a mortar. I then add a portion of the ricine or castor oil, and
afterwards the soft soap. After they have been well mixed I add the
rest of the constituents, and continue the trituration until the mixture is
complete.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not
confine myself to the precise quantities mentioned. But what I claim.
is, the above-described combination of materials, forming a grease or
composition for lubricating the axles and moving parts of machinery.
In witness whereof, I, the said Jean Emile Barse, have hereunto
set my hand and seal, this Twentieth day of August, in the year
of our Lord One thousand eight hundred and fifty-three.
