Year: 1869

page_text: LETTERS PATENT to Augustus Matthiessen, of No. 77, Carlton Hill,
St. John's Wood, in the County of Middlesex, for the Invention of
"A NEW OR IMPROVED INSULATING SUBSTANCE FOR THE COVERING OF ELECTRIC
TELEGRAPH CONDUCTING WIRES, AND FOR ELECTRIC TELEGRAPH APPARATUS AND
INSULATORS."
Sealed the 24th June 1870, and dated the 31st December 1869.
PROVISIONAL SPECIFICATION left by the said Augustus Matthiessen
at the Office of the Commissioners of Patents, with his Petition, on
the 31st December 1869.
I, AUGUSTUS MATTHIESSEN, of No. 77, Carlton Hill, St. John's Wood,
in the County of Middlesex, do hereby declare the nature of the said.
Invention for "A NEW OR IMPROVED INSULATING SUBSTANCE FOR THE COVERING OF
ELECTRIC TELEGRAPH CONDUCTING WIRES, AND FOR ELECTRIC TELEGRAPH APPARATUS
AND INSULATORS," to be as follows:-
My Invention consists in the application of a mineral or substance
known as "ozokerite" or "earth wax" found in Galicia and elsewhere
as an insulating coating for electric telegraph conducting wires, and for
electric telegraph apparatus and insulators. For this purpose I apply
such substance either in its natural state or the products obtained by.
partial or complete distillation thereof, or a mixture of either the natural

page_text: substance or of the said products with gutta percha, india-rubber, balata,
or other known insulating substances capable of incorporation with the
said substance. Such mixture is produced by heating both substances
together until their fusion is effected, and by incorporating them by
stirring or by any other suitable known means. The coating of the
telegraph wires may be effected with the above substance or the com-
pound by any known means or apparatus now employed for coating such
wires with gutta percha, india-rubber, or other plastic substances or
compounds.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Augustus Matthiessen in the Great Seal Patent
Office on the 29th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTUS
MATTHIESSEN, of No. 77, Carlton Hill, St. John's Wood, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of December, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Augustus Matthiessen, Her special
licence that I, the said Augustus Matthiessen, my executors, adminis-
trators, and assigns, or such others as I, the said Augustus Matthiessen,
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 "A NEW OR IMPROVED
INSULATING SUBSTANCE FOR THE COVERING OF ELECTRIC TELEGRAPH CONDUCTING
WIRES, AND FOR ELECTRIC TELEGRAPH APPARATUS AND INSULATORS," upon the
condition (amongst others) that I, the said Augustus Matthiessen, 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.

page_text: NOW KNOW YE, that I, the said Augustus Matthiessen, 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 :-
My Invention consists in the application of a mineral or substance
known as "ozokerite" or "earth wax" found in Galicia and elsewhere
as an insulating coating for electric telegraph conducting wires, and for
electric telegraph apparatus and insulators. For this purpose I apply
such substance either in its natural state or the residues or products
obtained by partial or complete distillation thereof, or a mixture of either
the natural substance or of the said residues or products with gutta
percha, india-rubber, balata, or other known insulating substances with
or without fibrous material, such as silk, wool, or any other suitable
fibre or fibrous residue, mica, asbestos, and similar substances capable of
incorporation with the said substance. Such mixture is produced by
heating the substances together until their fusion is effected, and by
incorporating them with or without the fibrous or other materials by
stirring or by any other suitable known means. The coating of the
telegraph wires may be effected by the above substance or the compound
by any known means or apparatus now employed for coating such
wires with gutta percha, india-rubber, or other plastic substances or
compounds.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, what I claim is, the application of
"ozokerito" or the residues or products of distillation thereof, and either
with or without admixture of other substances as an insulating coating
for telegraph wires, and for electric telegraph apparatus and insulators,
substantially as set forth.
In witness whereof, I, the said Augustus Matthiessen, have hereunto
set my hand and seal, this Twenty-eighth day of June, in the year
