IMPROVEMENTS IN INSULATING TELEGRAPHIC CONDUCTORS, AND MANU- FACTURING CABLES FOR TELEGRAPHIC PURPOSES
Year: 1859

page_text: LETTERS PATENT to Charles Hancock, of West Street, West Smithfield, in
the City of London, Gutta Percha Manufacturer, for the Invention of
"IMPROVEMENTS IN INSULATING TELEGRAPHIC CONDUCTORS, AND MANU-
FACTURING CABLES FOR TELEGRAPHIC PURPOSES."
Sealed the 12th June 1860, and dated the 15th December 1859.
PROVISIONAL SPECIFICATION left by the said Charles Hancock at the
Office of the Commissioners of Patents, with his Petition, on the
15th December 1859.
I, CHARLES HANCOCK, of West Street, West Smithfield, in the City of
London, Gutta Percha Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN INSULATING TELEGRAPHIC CONDUCTORS, AND
MANUFACTURING CABLES FOR TELEGRAPHIC PURPOSES," to be as follows:-
According to my Invention I take india-rubber that has been previously
vulcanized, and in that condition apply it on the wire or other conductor for
insulating purposes. I pass wire or other metallic conductor through tubes
made of vulcanized india-rubber, and afterwards bind or braid the same with
cords, tapes, or twine, or other suitable binding or braiding substance or
material. The tubes may be made of sufficiently thin material, to admit of
their stretching with ease over the wire or other conductor; they should then
be retained to the full stretch required whilst being bound around, as stated,

page_text: with
any
suitable material (preferably in the shape of cord, tape, or twine,)
that will ensure a close contact between the tube and wire or other conductor,
whether such conductor be of bare metal, or previously coated or insulated.
I also cover or insulate wire or other conductors with tapes, threads, fillets,
ribbons, or bands of vulcanized india-rubber alone, or combined with other
suitable material, by binding the tapes or other bindings around the wire or
other conductor, either spirally or by laying or arranging them longitudinally,
and then binding them with tapes or threads of the same material, or braiding
them over, or otherwise fixing the insulating tapes, bands, or bindings in their
proper position. The tubes, tapes, or other binders may, if required, be coated
with a cement or solution, in order to give adhesive property to the surface,
and for this purpose I manufacture a cement of a compound of masticated
india-rubber dissolved in a solvent composed of oil, gold size, and cold naptha.
Any number of wires coated according to any of the methods herein described
may be twisted or otherwise formed into cables of any size.
My Invention is also intended to be applied to wires or other conductors
which have been previously coated or covered with other insulating material
or materials, and other insulating materials may be placed upon wires and
other conductors which have previously been insulated by any of the means
which I have described above. The bands, ribbons, tapes, or other bindings
may be applied by any suitable machinery for taping and covering purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Hancock in the Great Seal Patent Office on the
15th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
HANCOCK, of West Street, West Smithfield, in the City of London, Gutta
Percha Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Charles Hancock, Her special licence that I, the said
Charles Hancock, my executors, administrators, and assigns, or such others
as I, the said Charles Hancock, 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

page_text: 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 INSULATING TELEGRAPHIC CONDUCTORS, AND MANUFACTURING
CABLES FOR TELEGRAPHIC PURPOSES," upon the condition (amongst others)
that I, the said Charles Hancock, 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 Hancock, 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:
According to my Invention I take india-rubber that has been previously
vulcanized, and in that condition apply it on the wire or other conductor for
insulating purposes. I pass wire or other metallic conductor through tubes
made of vulcanized india-rubber, and then fix or retain the tubes in place by
binding or braiding them with cords, tapes, or twine, or other suitable binding
or braiding substance or material. The tubes may be made of sufficiently
thin material, to admit of their stretching with ease over the wire or other
conductor; they should then be retained to the full stretch required whilst
being bound around, as stated, with any suitable material (preferably in the
shape of cord, tape, or twine,) that will insure a close contact between the
tube and wire or other conductor, whether such conductor be of bare metal,
or previously coated or insulated. I also insulate wire or other conductors
with tapes, threads, fillets, ribbons, or bands of vulcanized india-rubber alone,
or combined with other suitable material, by binding the tapes or other
bindings around the wire or other conductor, either spirally or by laying or
arranging them longitudinally, and then fix these insulating tapes, bands, or
bindings in the proper position by binding them with tapes or threads, or by
braiding them over, or by otherwise fixing them. The tubes, tapes, or other
binders before being applied on the wire may, if required, be coated with a
cement or solution, in order to give adhesive property to the surface, and for
this purpose I prefer a cement consisting of a compound of masticated india-
rubber dissolved in a solvent composed of oil, gold size, and coal tar naptha.
Any number of wires coated according to any of the methods herein described
may be twisted or otherwise formed into cables of any size.
My Invention in so far as it relates to the passing of wires through tubes of

page_text: vulcanized india-rubber may be applied to wires or other conductors which
have been previously coated or covered with other insulating material or
materials, and other insulating materials may be placed upon wires and other
conductors which have previously been insulated by any of the means which I
have described above. The bands, ribbons, tapes, or other bindings may be
applied by any suitable machinery for taping and covering purposes.
In witness whereof, I, the said Charles Hancock, have hereunto set my
hand and seal, this Fifteenth day of June, in the year of our Lord
One thousand eight hundred and sixty.
Witness,
M. HENRY, Patent Agent,
84, Fleet Street, London.
