TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
TEALL, LOUIS LEPAIGE, and EDWARD THORNHILL SIMPSON, of Wakefield, in the
County of York, Oil and Grease Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Teall, Louis Lepaige, and Edward Thornhill Simpson, Her
special licence that we, the said William Teall, Louis Lepaige, and Edward
Thornhill Simpson, our executors, administrators, and assigns, or such others
as we, the said William Teall, Louis Lepaige, and Edward Thornbill Simpson,
our 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 THE MANUFACTURE OF
LUBRICATING OIL AND GREASE," a communication to us from abroad by Emile
Lepaulle, of Paris, Engineer, upon the condition. (amongst others) that we,
the said William Teall, Louis Lepaige, and Edward Thornhill Simpson, our
executors or administrators, by an instrument in writing under our, or their,
or one of our or 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 we, the said William Teall, Louis Lepaige, and
Edward Thornhill Simpson, 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 (that is to say) :-
This Invention consists in the combining or mixing of petroleum or mineral
oil with the grease obtained from soapsuds or soapy or greasy waters. The.
proportions may vary from two-tenths to six-tenths of the recovered grease
for producing the lubricating oil, and a larger proportion of the recovered

page_text: grease is used when producing the lubricating grease, the remainder being
mineral oil.
The manner in which this Invention is performed or carried into practical
operation is by a simple process of placing the two articles together in any
suitable vessel, in any proportions, according to the kind or quality of the
admixture or compound required to be produced. The mixing may then be
done by either hand or mechanical means. They are generally mixed in a
warm or heated state, but will mix in a cold state, as these ingredients have
such affinity for each other that they readily mix or combine.
In witness whereof, I, the said William Teall, for and on behalf of
myself and the said Louis Lepaige, and Edward Thornhill Simpson,
have hereunto set my hand and seal, this Second day of October, One
thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
within-named William Teall, in
the presence of
WILLIAM WHITTON.
WILLIAM TEALL. (L.S.)
