IMPROVEMENTS IN SUBMARINE ELECTRIC TELEGRAPH CABLES."
Year: 1865

page_text: LETTERS PATENT to Stopford Thomas Jones, of No. 11, Oxford Terrace,
Peckham, in the County of Surrey, for the Invention of "IMPROVEMENTS
IN SUBMARINE ELECTRIC TELEGRAPH CABLES."
PROVISIONAL SPECIFICATION' left by the said Stopford Thomas Jones at
the Office of the Commissioners of Patents, with his Petition, on the
28th August 1865.
I, STOPFORD THOMAS JONES, of No. 11, Oxford Terrace, Peckham, in the
County of Surrey, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SUBMARINE ELECTRIC TELEGRAPH CABLES," to be
as follows:-
The objects of my Invention are to reduce the specific gravity of the cable
to render it buoyant, whereby friction will be considerably if not altogether
prevented; to lessen the possibility of the cable being worn or. cut by the
action of currents or by frictions; to retain the cable in a state of suspension
at any desirable depth by giving it buoyancy. To effect one or all of these
objects I apply an internal or external covering of cork cemented together by
a solution of gutta percha or other cement.

and of an Order of the Lord Chancellor, by the said Stopford Thomas
Jones in the Great Seal Patent Office on the 6th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STOPFORD
THOMAS JONES, of 11, Oxford Terrace, Peckham, in the County of Surrey,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Stopford Thomas Jones, Her special licence that I, the said
Stopford Thomas Jones, my executors, administrators, and assigns, or such
others as I, the said Stopford Thomas Jones, 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 SUBMARINE ELECTRIC TELEGRAPH CABLES,"
upon the condition (amongst others) that I, the said Stopford Thomas
Jones, 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 Stopford Thomas Jones, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of my Invention is to give to the cable any degree of buoyancy
that may be found desirable, by enveloping the insulator with cork; I prefer
leaf or sheet cork for this purpose, to be made adhesive with cement if
required; the quantity of cork is easily ascertainable by or according to the
specific gravity of the cable to be used. From the buoyancy of this cable
it will descend in the water so gradually there will be scarcely any strain in
paying it out, and when laid at the bottom there will be little or no friction,
consequently it will be durable.
claim the introduction of cork in the construction of submarine electric

page_text: telegraph cables internally or externally to give the cable buoyancy and to
reduce or prevent friction.
In witness whereof, I, the said Stopford Thomas Jones, have hereunto
set my hand and seal, this Sixth day of March, in the year of our
Lord One thousand eight hundred and sixty-six.
STOPFORD THOMAS JONES. (L.S.)
