TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OSWALD
EARLE, of Liverpool, in the County of Lancaster, Manufacturing Chemist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of March, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Oswald Earle, Her special license that I, the said Oswald Earle,
my executors, administrators, and assigns, or such others as I, the said
Oswald Earle, my executors, administrators, or 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 "AN IMPROVED
LUBRICATING COMPOUND," upon the condition (amongst others) that I, the said
Oswald Earle, my executors or administrators, by an instrument in writing
under my hand and seal, or under the hand and seal of one of them,
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 Oswald Earle, 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, that is to say :-
My said Invention relates to the manufacture or production of a new
lubricating compound, and consists in the admixture of lime water with oils,
whereby an economical and efficient lubricant is obtained.
In carrying out my Invention in practice, I make a solution of lime either
by direct solution of caustic lime in water until a thoroughly saturated
solution is obtained, or I produce the lime water by the chemical decomposition
of a solution of salt of lime. This solution of lime or lime water is then
mixed in about equal proportions with either spurm, olive, rape, lard, fish, or
animal oils, and well agitated.
Having now described and particularly ascertained the nature of my said

page_text: Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion, that what I consider to be novel and
original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent, is, the manufacture or production of a
lubricating compound by mixing a saturated solution of lime in water with oil,
as herein-before described.
In witness whereof, I, the said Oswald Earle, have hereunto set my
hand and seal, this Twenty-fifth day of September, One thousand
eight hundred and sixty-one.
OSWALD EARLE. (LS.)
