page_text: LETTERS PATENT to Henri Adrien Bonneville, of the British and
Foreign Patent Offices, 18, Rue de la Chaussée d'Antin, Paris,
France, and 6, Piccadilly, in the County of Middlesex, Patent
Agent, for the Invention of " CERTAIN IMPROVEMENTS IN CONDUCTORS
FOR TELEGRAPH WIRES."-A communication from William Radde,
residing in the City, County, and State of New York, United States
America, Bookseller.
Sealed the 5th December 1873, and dated the 13th June 1873.
PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition,
on the 13th June 1873.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent
Offices, 18, Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly,
in the County of Middlesex, Patent Agent, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN CONDUCTORS FOR
TELEGRAPH WIRES," communicated to me by William Radde, a person

page_text: resident in the City, County, and State of New York, United States of
America, Bookseller, to be as follows:-
This Invention consists in the arrangement of an insulated bridge
enclosed in a box, which forms the connecting link between sections of
pipes, which enclose one or more telegraph wires in such a manner that
by opening said box access can be had to the wire or wires whenever it
may be desirable. Also in a pipe containing a series of insulated
passages, which are separated from each other, and from the enclosing
shell, by a layer of cement, bitumen, plaster Paris, or other suitable
material, in such a manner that a separated passage is obtained for each
of a series of telegraph wires in the smallest possible compass.
This Invention is illustrated in the accompanying Drawing, in which
Figure 1 represents a longitudinal section of this Invention; Figure 2 is
a transverse section of the same; Figure 3 is a plan or top view of the
same, the cover of the box being removed, and showing several bridges
for carrying the wires in different directions; Figure 4 is a transverse
section of the pipe. Similar letters indicate corresponding parts.
In the Drawing the letter A designates a box made of cast iron, or
any other suitable material, and provided with a cover B, so that by
removing said cover access can be had to the interior of the box.
The ends of the box connect with pipes C, C, which represent sections
of a conductor for telegraph wires, and which may be arranged with one
or more passages, according to the number of telegraph wires to be
passed through the same. Each passage of these pipes is lined with
glass, or other bad conductor of electricity, and separated from the
remaining passages by a layer of cement, bitumen, plaster Paris, or
other suitable material, and the whole is protected by a common shell of
metal, or other suitable material (see Fig. 4).
In the interior of the box A is secured an insulated bridge D provided
with one or more notches a (see Fig. 2), through which the wire or
wires are passed. Or if it is desired to carry the telegraph wires in
different directions several bridges are arranged in the box A, as shown
in Fig. 3. By this arrangement easy access can be had to any part of
the telegraph wire or wires, and repairs can be effected with facility.
The conductors C, O, may, for instance, be used in cities for the wires of
fire alarm telegraphs. In this case said conductors are provided with a

page_text: multiplicity of passages, one insulated from the other, so as to make
room for the required number of wires.
If the conductors are placed under ground, and one of the wires gets
broken or inoperative, it is impossible to repair the same without much
trouble and expense, and for this reason subterranean conductors for
telegraph wires have not been considered pratical. But by my improve-
ment I am enabled to repair each wire with the greatest facility. The
bridge containing boxes A will be distributed at suitable intervals along
the line, and if either of the wires becomes inoperative it can readily be
determined by an electro-meter where the faulty place exists in the wire,
and by opening the boxes next to this place the fault can be remedied
without much trouble.
In order to facilitate the operation of picking out the faulty wire the
notches in the bridges are numbered to correspond to the numbers of
the wires; and if it is found, for instance, that wire 4 is inoperative the
wire is easily picked out by opening the boxes, and looking at the
numbers marked on the bridges.
By my improvement subterranean conductors for telegraph wires are
rendered praticable, and any repairs which may be required on such
wires can be made with as much ease as on wires suspended on
poles.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henri Adrien Bonneville in the Great Seal Patent
Office on the 6th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18, Rue
de la Chaussée, d'Antin, Paris, France, and 6, Piccadilly, in the County
of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of June, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Henri Adrien Bonneville, Her special licence that
I, the said Henri Adrien Bonneville, my executors, administrators, and

page_text: assigns, or such others as I, the said Henri Adrien Bonneville, 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 "CERTAIN IMPROVE-
MENTS IN CONDUCTORS FOR TELEGRAPH WIRES," communicated to me by William
Radde, a person resident in the City, County, and State of New York,
United States of America, Bookseller, upon the condition (amongst
others) that I, the said Henri Adrien Bonneville, 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 Henri Adrien Bonneville, 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:-
This Invention consists in the arrangement of an insulated bridge
enclosed in a box, which forms the connecting link between sections of
pipes, which enclose one or more telegraph wires in such a manner that
by opening said box access can be had to the wire or wires whenever it
may be desired. Also in a pipe containing a series of insulated passages,
which are separated from each other, and from the enclosing shell by a
layer of cement, bitumen, plaster Paris, or other suitable material, in
such a manner that a separated passage is obtained for each of a series
of telegraph wires in the smallest possible compass.
This Invention is illustrated in the accompanying Drawing, in which
Fig. 1 represents a longitudinal section of this Invention; Fig. 2 is a
transverse section of the same; Fig. 3 is a plan or top view of the same,
the cover of the box being removed, and showing several bridges for
carrying the wires in different directions; Fig. 4 is a transverse section
of the pipe. Similar letters indicate corresponding parts.
In the Drawing the letter A designates a box made of cast iron, or
any other suitable material, and provided with a cover B, so that b

page_text: removing said cover access can be had to the interior of the box. The
ends of the box connect with pipes C, which represent sections of a
conductor for telegraph wires, and which may be arranged with one or
more passages, according to the number of telegraph wires to be passed
through the same. Each passage of these pipes is lined with glass, or
other bad conductor of electricity, and separated from the remaining
passages by a layer of cement, bitumen, plaster Paris, or other suitable
material, and the whole is protected by a common shell of metal, or
other suitable material (see Fig. 4).
In the interior of the box A is secured an insulated bridge D provided
with one or more notches a (see Fig. 2), through which the wire or
wires are passed. Or if it is desired to carry the telegraph wires in
different directions several bridges are arranged in the box A, as shown
in Fig. 3. By this arrangement easy access can be had to any part of
the telegraph wire or wires, and repairs can be effected with facility.
The conductors C, C, may, for instance, be used in cities for the wires of
fire alarm telegraphs. In this case said conductors are provided with a
multicity of passages, one insulated from the other, so as to make
room for the required number of wires.
If the conductors are placed under ground, and one of the wires gets
broken or inoperative, it is impossible to repair the same without much
trouble and expense, and for this reason subterranean conductors for
telegraph wires have not been considered practical. But by my improve-
ment I am enabled to repair each wire with the greatest facility. The
bridge containing boxes A will be distributed at suitable intervals along
the line, and if either of the wires becomes inoperative it can readily be
determined by an electro-meter where the faulty place exists in the wire,
and by opening the boxes next to this place the fault can be remedied
without much throuble.
In order to facilitate the operation of picking out the faulty wire the
notches in the bridges are numbered to correspond to the numbers of the
wires; and if it is found, for instance, that wire 4 is inoperative the wire
is easily picked out by opening the boxes, and looking at the numbers
marked on the bridges.
By my improvement subterranean conductors for telcoranh wire ara

page_text: wires can be made with as much ease as on wires suspended on
poles.
Having thus described the nature of the said Invention, I claim and
wish to secure my Letters Patent,-
The arrangement of boxes A containing insulated bridges D between
the sections C, C, of a conductor for telegraph wires, substantially as
and for the purpose herein shown and described.
Also a pipe containing a number of passages, each of which is lined
with glass, or other non-conductor of electricity, and separated from the
remaining passages by a layer of cement, bitumen, plaster Paris, or
other sutable material, as shown and described.
In witness whereof, I, the said Henri Adrien Bonneville, have here-
unto set my hand and seal, this Twenty-ninth day of November,
in the year of our Lord One thousand eight hundred and
seventy-three.
