IMPROVEMENTS IN-OILING WOOL
Year: 1864

page_text: the City of Glasgow, Civil Engineer and Patent Agent, for the Invention
of "IMPROVEMENTS IN-OILING WOOL."A communication from abroad by
Benjamin Head Lightfoot, of Philadelphia, Pennsylvania, United States
of America.
Sealed the 28th March 1865, and dated the 7th October 1864..
PROVISIONAL SPECIFICATION left by the said George Davies at the
"Office of the Commissioners of Patents, with his Petition, on the
7th October 1864.
.
I, GEORGE DAVIES, of No. 1, Serle Street, Lincoln's Inn, in the County of
Middlesex, and No. 28, St. Enoch Square, in the City of Glasgow, Civil
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN OILING WOOL," (a communication to me from
abroad by Benjamin Head Lightfoot, of Philadelphia, Pennsylvania, United
States of America,) to be as follows:-
This Invention consists in the use, for oiling wool, of petroleum or other oily
hydrocarbons, also in the use, for the same purpose, of petroleum or other oily
bydrocarbons in combination with olein oil or lard oil, or other equivalent
material.
After repeated experiments it has been found that oily hydrocarbons may be

page_text: used to great advantage for cleaning wool or for oiling the same prior to
carding it.
Oily bydrocarbons, being solvents of gummy matters, readily remove from
wool all traces of such substances which may remain after the wool has been
washed, and thus render the wool less liable to spontaneous combustion than
the materials usually employed for a similar purpose.
As regards economy it will be evident to those familiar with the process
that a great saving is effected by the practice of this Invention.
Although any of the oily hydrocarbons may be used it has been found that
the most efficient for the purpose is the ordinary petroleum refined until it has
reached a-gravity of from 30 to 40 degrees Beaumé.
By mixing the petroleum (or other oily hydrocarbons) with about one-third of
its weight of olein oil or lard-oil a very excellent composition for cleaning and
oiling wool is produced, the olein or lard oil having a tendency to deodorize
the hydrocarbon, while the latter dissolves the gummy matter in the olein or
lard oil.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Davies in the Great Seal Patent Office on. the
4th April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, GEORGE
DAVIES, of No. 1, Serle. Street, Lincoln's Inn,, in the County of Middlesex,
and No. 28, St. Enoch Square, in the City of Glasgow, Civil Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of October, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did for Herself, Her heirs and successors, give and grant unto
me, the said George Davies, Her special licence that' I, the said
George Davies, my executors, administrators, and assigns, or such others
as I, the said George Davies; -my-executors,- administrators, and assigns,
sliould 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 "IM-
PROVEMENTS IN OILING WOOL," (a. communication to me from abroad by

page_text: Benjamin Head Lightfoot, of Philadelphia, Pennsylvania, United States of
America, upon the condition (amongst others) that I, the said George Davies,
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 George Davies, 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 in writing, that is to say :-
This Invention consists in the use for oiling wool of petroleum or other
oily hydrocarbons, also in the use for the same purpose of petroleum or other
oily hydrocarbons in combination with olein oil or lard oil, or other equivalent
material.
After repeated experiments it has been found that oily hydrocarbons may
be used to great advantage for cleaning wool or for oiling the same prior to
carding it.
Oily hydrocarbons, being solvents of gummy matters, readily remove from
wool all traces of such substances which may remain after the wool has been
washed, and thus render the wool less liable to spontaneous combustion than
the materials usually employed for a similar purpose.
As regards economy it will be evident to those familiar with the process
that a great saving is effected by the practice of this Invention.
Although any of the oily hydrocarbons may be used it has been found that
the most efficient for the purpose is the ordinary petroleum refined until it has
reached a gravity of from 30 degrees to 40 degrees Beaumé.
By mixing the petroleum (or other oily hydrocarbons) with about one-third of
its weight of olein oil or lard oil a very excellent composition for cleaning and
oiling wool is produced, the olein or lard oil having a tendency to deodorize
the hydrocarbon, while the latter dissolves the gummy matter in the olein or
lard oil.
Having now particularly described the nature and object of the said Inven-
tion for "Improvements in Oiling Wool," together with the manner in which
the same is to be or may be performed or carried into practical effect, I
would remark in conclusion that I claim as the Invention communicated to
me by the said Benjamin Head Lightfoot,―

page_text: Firstly, the application of petroleum or other, oily bydrocarbons to the
oiling of wool..
...
Secondly, the application to the oiling of wool of oily hydrocarbons in com-
bination with olein or lard oil or other equivalent material.
In witness whereof, I, the said George Davies, have hereunto set my
hand and seal, this Fourth day of April, in the year of our Lord One
thousand eight hundred and sixty-five.'
GEORGE DAVIES. (L.S..)
