Year: 1857

page_text: LETTERS PATENT to Charles Emilus Wright, of Green Street, Black-
friars, for the Invention of "IMPROVEMENTS IN PREPARING LUBRICATING....
COMPOUNDS."
Sealed the 3rd July 1857, and dated the 6th January 1857.
PROVISIONAL SPECIFICATION left by the said Charles Emilus Wright
at the Office of the Commissioners of Patents, with his Petition, on
the 6th January 1857.
I, CHARLES EMILUS WRIGHT, of Green Street, Blackfriars, do hereby
5 declare the nature of the Invention for "IMPROVEMENTS IN PREPARING LUBRI-
CATING COMPOUNDS," to be as follows:-
This Invention has for its object improvements in preparing lubricating
compounds, and consists in combining soap, tallow, palm oil, Venice turpentine,
and water. These matters may be combined in varying quantities or pro-
portions.
The best preparation I, however, believe to be as follows:-Equal quantities
of soap and tallow are melted together (say 3 cwt. of each). The Venice tur-
pentine (about 42 lbs.) is mixed with palm oil (about 63 lbs.), and this mixture
is added to and combined with the soap and tallow. A suitable quantity of
boiling water is added to the mixture of soap and tallow before or after adding
the mixture of palm oil and Venice turpentine. These quantities and mode of
mixing may be varied.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
EMILUS WRIGHT, of Green Street, Blackfriars, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of January, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Emilus Wright, Her special licence that I, the said Charles
Emilus Wright, my executors, administrators, and assigns, or such others as
I, the said Charles Emilus Wright, my 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 PREPARING LUBRICATING COMPOUNDS," upon the condition
(amongst others) that I, the said Charles Emilus Wright, 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 Charles Emilus Wright, 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 :-
This Invention has for its object improvements in preparing lubricating
compounds, and consists in combining soap, tallow, palm oil, Venice turpentine,
and water. These matters may be combined in varying quantities or pro-
portions.
The best preparation I, however, believe to be as follows:-Take equal
quantities of soap and tallow, say three cwt. of each, and melt them together
in any convenient vessel. Dissolve about 42 lbs. of Venice turpentine in about
63 lbs. of palm oil. This mixture is then to be added to and thoroughly
incorporated with the melted soap and tallow, so as to form a material of
uniformi consistency. A suitable quantity of boiling water is to be added to

page_text: this composition in order to bring the mixture to the ordinary or any other
required consistency. This water may be added either after the whole of the
materials have been combined or it may be mixed with the melted soap and
tallow.
These proportions may be varied by increasing or diminishing the quantities
of any of the materials when the composition is required to possess more or less
of the qualities of such materials.
During the formation of this composition I keep the mixture in constant
agitation by means of a wooden crutch or other suitable instrument. When all
the materials have been thoroughly incorporated and combined, I remove the
composition to broad flat coolers, where the agitation is continued until the
grease is cold, when it may be packed in casks for use.
In witness whereof, I, the said Charles Emilus Wright, have hereunto
set my hand and seal, this Sixth day of July, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
S. CARPMAEL.
CHARLES EMILUS WRIGHT. (L.S.)
