Year: 1855

page_text: LETTERS PATENT to George Durham, of No. 3, Drummond Crescent,
Euston Square, and Cornelius Wyatt, of 1, Conduit Street, Regent
Street, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
GREASE FOR LUBRICATING THE AXLES OF RAILWAY AND OTHER CARRIAGES,

"
PROVISIONAL SPECIFICATION left by the said George Durham and
Cornelius Wyatt at the Office of the Commissioners of Patents, with
their Petition, on the 10th August 1855.
We, GEORGE DURHAM, of No. 3, Drummond Crescent, Euston Square, and
CORNELIUS WYATT, of 1, Conduit Street, Regent Street, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
GREASE FOR LUBRICATING THE AXLES OF RAILWAY AND OTHER CARRIAGES, AND THE
JOURNALS OF MACHINERY GENERALLY," to be as follows:-
These improvements consist in compounding certain ingredients, not hereto-
fore employed in combination, into a grease or lubricating composition, designed
for reducing the friction of the axles of railway and other carriages, and the
journals of machinery generally; at less cost and in a more efficient manner
than heretofore. The ingredients employed in and for the manufacture of
grease according to this Invention are as follows, namely, tallow, soap, resin,
and water, the whole being thoroughly mixed and incorporated together by
any suitable means.

Patent Office on the 9th February 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
DURHAM, of No. 3, Drummond Crescent, Euston Square, and CORNELIUS
WYATT, of 1, Conduit Street, Regent Street, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of August, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
George Durham and Cornelius Wyatt, Her special licence that we, the
said George Durham and Cornelius Wyatt, our executors, administrators, and
assigns, or such others as we, the said George Durham and Cornelius Wyatt,
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 GREASE FOR
LUBRICATING THE AXLES OF RAILWAY AND OTHER CARRIAGES, AND THE JOURNALS OF
MACHINERY GENERALLY," upon the condition (amongst others) that we, the said
George Durham and Cornelius Wyatt, by an instrument in writing under our
hands and seals, or under the hand and seal of one of us, 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 George Durham and Cornelius Wyatt,
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:-
These improvements consist in compounding certain ingredients into a
grease or lubricating composition, designed for reducing the friction of the
axles of railway and other carriages, and the journals of machinery generally.
The ingredients employed in and for the manufacture of grease according to
this Invention, and the mode of combining the same, are as follows:-I take,
say, one ton of tallow, half a ton of soap, and two hundredweight of resin, or
in like proportions; but in cold weather a less quantity of resin, say, one
hundredweight, will be sufficient. To these ingredients 1 add warm water in

page_text: such quantity as to reduce the mixture to a semi-fluid state, or the consistence
of flour paste. The tallow and soap may either be melted together or
separately in a vessel suitable for the purpose, and when mixed together the
water is added thereto. The resin is then added in a melted state, and
the whole thoroughly mixed and incorporated together by stirring until cool.
The grease is then fit for use.
Having now described the nature of our said Invention, and in what manner
the same is to be performed, we hereby declare that we claim as of our Inven-
tion, the manufacture of grease compounded of the materials and in the manner
berein-before described.
In witness whereof, we, the said George Durham and Cornelius Wyatt,
have hereunto set our hands and seal, this Seventh day of February;
in the year of our Lord One thousand eight hundred and fifty-six.
