Year: 1870

page_text: LETTERS PATENT to Samuel Elkens Phillips, of Francis Terrace,
Hackney Wick, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN ELECTRIC CARING OR CANDHARA "
Sealed the 30th August 1870, and dated the 3rd March 1870.
PROVISIONAL SPECIFICATION left by the said Samuel Elkens Phillips
at the Office of the Commissioners of Patents, with his Petition, on
the 3rd March 1870.
I, SAMUEL ELKENS PHILLIPS, of Francis Terrace, Hackney Wick, in
the County of Middlesex, do hereby declare the nature of my said In-
vention for "IMPROVEMENTS IN ELECTRIC CABLES OR CONDUCTORS," to be as
follows:-
This Invention consists in lapping with strips of gutta percha in one
or more layers a conducting wire, and in covering the same with a
protecting or separating material of suitable form and consistence, such,
for instance, as shellac, and finally applying an outer protective coating
or covering of some flexible waterproof material, by preference one
containing xyloidine, such, for example, as is described amongst others
in the Specifications of Edward Orange Wildman Whitehouse, No. 3224,

page_text: 1868, and Daniel Spill, No. 3984, 1868, whereby a highly insulated
and protected conductor is obtained with a much smaller quantity of
insulating material, and at less cost than by any other mode heretofore
in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Elkens Phillips in tlic Great Seal Patent
Office on the 2nd September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
ELKENS PHILLIPS, of Francis Terrace, Hackney Wick, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of March, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Samuel Elkens Phillips, her special license that I, the
said Samuel Elkens Phillips, my executors, administrators, and assigns,
or such others as I, the said Samuel Elkins Phillips, my executors,
administrators, or 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 ELECTRIC
CABLES OR CONDUCTORS," upon the condition (amongst others) that I, the
said Samuel Elkens Phillips, my executors or administrators, by an
instrument in writing under my hand and seal, 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 Samuel Elkens Phillips, 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, that is to say :-
My said Invention consists in lapping with strips of gutta percha in
one or more layers a conducting wire or wires and the cementing and

page_text: covering the same with a protecting or separating material of suitable
form and consistence, such, for instance, as shellac or a thin tape of
xylonite, and finally applying an outer protective coating or covering of
some flexible waterproof material, by preference one containing xyloidine,
such, for example, as is described amongst others in the Specifications of
Edward Orange Wildman Whitehouse, No. 3224, One thousand eight
hundred and sixty-eight, and Daniel Spill, No. 3984, One thousand
eight hundred and sixty-eight, whereby a highly insulated and protected
conductor is obtained with a much smaller quantity of insulating
material and.at less cost than by any other mode heretofore in use. I
have found in practice that a good result is obtained by the use of the
thin sheet gutta percha known in the trade as gutta" tissue or strained
"sheet" gutta.
"
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the peculiar
mode of insulating electric conductors herein-before described.
In witness whereof, I, the said Samuel Elkens Phillips, have
to this my Specification set my hand and seal, the First day
of September One.thousand eight hundred and seventy.
SAMUEL ELKENS PHILLIPS. (L.S.)
