page_text: LETTERS PATENT to James Gordon, of Park House, in the Parish of
Gateshead, and County of Durham, Manufacturer, and Bartholomew
Henderson, of the South Shore, Gateshead, in the County of Durham,
aforesaid, Engineer, for the Invention of "IMPROVEMENTS IN THE MANU-
PROVISIONAL SPECIFICATION left by the said James Gordon and Bartho-
lomew Henderson at the Office of the Commissioners of Patents, with
their Petition, on the 30th December 1861.
We, JAMES GORDON, of Park House, in the Parish of Gateshead, and County
of Durham, Manufacturer, and BARTHOLOMEW HENDERSON, of the South Shore,
Gateshead, in the County of Durham, aforesaid, Engineer, do hereby declare
the nature of our Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ROPES,"
to be as follows:-
Our Invention has for its object the diminution of risk from fire by the
ordinary use of boiling tar in preparing the hempen yarn of which ropes are
made, and also the preservation of the yarn from decay.
For this purpose, instead of using boiling tar we use coal oil, either
alone or mixed with tar in such different proportions as may be required for
different kinds of rope, and we use such saturating material or materials either
in a cold state or warmed.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed

TO ALL TO WHOM THESE PRESENTS SHALL COME,, we, JAMES
GORDON, of Park House, in the Parish of Gateshead, in the County of Durham,
Manufacturer, and BARTHOLOMEW HENDERSON, of the South Shore, Gateshead,
in the County of Durham, aforesaid, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of December, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said James Gordon and Bartholomew Henderson, Her special license that
we, the said James Gordon and Bartholomew Henderson, our executors,
administrators, and assigns, or such others as we, the said James Gordon and
Bartholomew Henderson, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF ROPES," upon the condition (amongst others)
that we, the said James Gordon and Bartholomew Henderson, by an instru-
ment 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 Inven-
tion, 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 James Gordon and Bartholomew
Henderson, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
Our Invention of "Improvements in the Manufacture of Ropes," has for
its object the diminution of risk from fire by the ordinary use of boiling tar
in preparing the hempen yarn of which ropes are made, and also the preserva-
tion of the yarn from decay.
For this purpose instead of using boiling tar we use coal oil, either alone
or mixed with tar in such different proportions as may be required for different
kinds of rope, and we use such saturating material or materials, either in a
cold state or warmed.

page_text: The Invention thus consists in the substitution of coal oil either alone or
mixed with tar in suitable proportions for boiling tar in preparing the hempen
yarn. In other respects the manufacture of ropes is the same as usual.
Having thus described the nature of the said Invention and in what manner
the same is to be performed, we hereby declare that what we claim as of
our Invention is, the use of coal oil either alone or mixed with tar in
suitable proportions in preparing the hempen yarn of which ropes are made.
In witness whereof, we, the said James Gordon and Bartholomew
Henderson, have hereunto set our hands and seals, the Twenty-
eighth day of June, in the year of our Lord One thousand eight
hundred and sixty-two.
JAMES GORDON.
