PAUL RAOUL DE FAUCHEUX D'HUMY of Carlton Mansions Clapham Road, in
the County of Surrey IMPROVEMENTS IN WIRES OR CONDUCTORS FOR ELECTRICAL
PURPOSES AND IN THE INSULATION THEREOF, AND IN MEANS OR APPARATUS AND
MATERIALS EMPLOYED THEREIN
"
The Invention has for its object improvements in wires or conductors for
electrical purposes and in the insulation thereof and in means or apparatus and
materials employed therein.
For this purpose I. form the wire of copper or other suitable metal either round,
flat or grooved.
This wire I pass through a bath consisting of the following ingredients in about
the proportions stated and which bath is hereinafter referred to as bath A.
Bath A.
India Rubber.
Powdered glass

I then encase the wire in strips filaments or rods of desiccated wood, glass or
other suitable material which has previously been passed through a bath of
soluble glass and I pass the wire so covered through bath A, one or more
times according to the thickness of the coating required and then wind it upon a
bobbin.

page_text: The wire is then gradually unwound from the bobbin and passed through a
heated cylinder to soften the coating and is then passed through powdered glass,
powdered talc, powdered asbestos, cotton wool or other suitable material which
adheres to the coating. The wire is then passed between two wheels or rolls formed
with semi-circular or other shaped recesses upon their peripheries to compress the
covering material and subdivide it into the form of beads or sections so as to give
the required flexibility to the wire.
Or I pass the wire in the first instance through a bath of soluble glass and then
through bath A, and I then introduce the wire into a tube of desiccated wood or
other suitable material.
The wire so covered is then passed through a bath of soluble glass and then
through the bath A, after which it is passed through the heated cylinder and
finished by being passed through the powdered material and rolls in the manner
before mentioned.

Or I first form a number of fine longitudinal grooves in the wire and then twist 1
it as to form spiral threads around the same. This twisted wire is then passed
through a bath consisting of the following ingredients in about the proportions
stated and after being passed through water is wound upon a bobbin.
Pulp of paper, wood, felt, cotton or similar
material
India rubber
Powdered glass

The wire so covered is then unwound from the bobbin and passed through
bath A and through the heated cylinder and powdered material and rolls as before
mentioned. Or the wire finely grooved is first laid in a mould or form containing 2
filaments of spun glass which have been previously passed through a solution of
Camphor, Resin, Turpentine and Linseed or other suitable oil in about equal parts
to cause them to adhere together.
The wire so covered is then removed from the mould or form and exposed to a
sharp flame or passed through a highly heated cylinder in order to fuse the glass 3
and burn off the last mentioned solution.
The glass coated wire is then passed through bath A, then through the heated
cylinder and powdered material and rolls in the manner above mentioned.
Or I first pass the wire which may be either plain or finely grooved or twisted
or otherwise shaped through bath A, and through a number of beads formed of 3
glass or other material arranged in a form and I then remove the bead- covered
wire from the form and pass it through a heated cylinder in order to fuse the
coating of solution and thus cause the beads to adhere to the wire, thus finishing
it. Or I pass the wire previously shaped or not, through a number of perforated
discs of paper, cardboard, papier maché or other suitable material which have 4
previously been saturated with a solution of soluble glass. I then pass the wire so
covered through bath A and then through the heated cylinder and powdered
material and rolls as before mentioned.
Or I draw the wire, which may be either plain or shaped, through molten glass
and while the glass is still fused I pass. the glass covered wire directly through the 4
rolls herein before described to finish it.. In some cases I may afterwards pass the
glass coated wire through bath A and then through the heated cylinder and
powdered material and through the rolls as before described.
Or I thread the wire either plain or shaped through a tube of glass and I then
heat the wire and tube and pass them quickly. through cold water. This has the 5
effect of causing the glass tube to break up transversely into a number of small
sections or beads. The wire covered with these beads is then passed through
bath A, then through the heated cylinder and powdered material and rolls as
before mentioned

page_text: wire through a suitable guide I cause the edges of the strip to approach each other
with the wire in the centre of the tube so formed.
The wire so covered is then passed through a bath of soluble glass and then
through the bath A after which it is passed through the heated cylinder b and
finished by being passed through the powdered or other insulating material and
rolls c, c. in the manner and for the purpose before mentioned.
This
According to another method I first form a number of fine longitudinal grooves
in the wire and then twist it so as to form spiral threads around the same.
twisted wire is then passed through a bath consisting of the following ingredients in
about the proportions stated and after being passed through cold water or other
material to prevent sticking it is wound upon a bobbin a.
Bath B
Pulp of paper, wood, felt cotton } 50 parts by weight
or similar fibrous material
India rubber (dissolved)
Powdered glass

The wire after having passed through the processes above described is then as
before described unwound from the bobbin a, and passed through bath A and
through the heated cylinder or chamber b, and powdered or other insulating material
and rolls c. c. as before mentioned.'
Or the wire finely grooved is first laid in a mould or form containing filaments
of spun glass which have been previously passed through a solution of camphor
resin turpentine and linseed or other suitable oil in about equal parts to cause
them to adhere together.
:
Or the spun glass may be wound round the wire without the latter having been
previously passed through the last mentioned solution.
The wire so covered is then removed from the mould or form and exposed to a
sharp flame or passed through a highly heated cylinder or chamber in order to fuse
the glass and burn off the last mentioned solution when such is employed.
The glass coated wire is then passed through bath A then through the heated
cylinder or chamber band powdered material and between the rolls c, c, in the
manner above described.
Or I first pass the wire which may be either plain or finely grooved and twisted
or otherwise shaped through bath A as before described and then through a
number of beads formed of glass or other insulating material arranged in a
form and I then remove the bead covered wire from the form and pass it
through a heated cylinder or chamber in order to fuse the coating of solution
and thus cause the beads to adhere to the wire thus finishing it. In order
to facilitate the placing of the beads on the wire, I provide a number of forms con-
structed as shewn at Figures 2 and 3 of tubes divided longitudinally and hinged
together. These half tubes are lined with india rubber and provided with suitable
fastening means. I then thread beads on to a short length of wire which I after-
wards place in the form Figures 2 and 3 then when the two halves of the said form
are fastened together I withdraw the short length of wire and leave the beads in
position in the form, the wire can then be readily passed through the beads in the
form. By these means I am enabled to employ a number of hands threading beads
on to the short lengths of wire and preparing the beads for ready application to the
long length of wire.
Or I pass the wire either plain or grooved and twisted or otherwise through a
number of perforated discs of paper, cardboard, papier maché or other suitable
insulating material which have previously been saturated with a solution of soluble
glass, I then pass the wire so covered through bath A and then through the heated
cylinder or chamber b and powdered material and rolls c, c, as before mentioned.
Or as before described I draw the wire which may be either plain or shaped,
through molten glass and while the glass is still fused I pass the glass covered
wire directly through the rolls c, c, hereinbefore described to finish it.
In some
cases I may afterwards pass the glass coated wire through bath A and then through

page_text: the heated cylinder or chamber b and powdered, material and then through the
rolls c. c. as before described..
.
Or I thread the wire either plain or shaped through glass tubing and I then
heat the wire and tube and pass them quickly through cold water. This has the
effect of causing the glass tube to break up transversely into a number of small
sections or beads. The wire covered with these sections, or beads is then passed
through bath A then through the heated cylinder or chamber b and powdered or
other insulating material and then through the rolls c. c. as before mentioned.
Having thus described the nature of the said Invention and the mode in which
I carry the same into effect I would have it understood that what I claim is.
First. The employment of grooved wire either twisted or straight in the
manufacture of insulated wires or conductors for electrical purposes.
Second. The insulation of wires or conductors for electrical purposes by the
application thereto of soluble or fusible glass either. alone or in combination with
the other materials and processes substantially as herein described.
Third. The employment in the manufacture of insulated wires or conductors for
electrical purposes of wheels or rolls c, c, and of india rubber lined tube d, substan-
tially as herein shewn and described and for the purposes stated.
Fourth. The employment in the manufacture of insulated wires or conductors
for electrical purposes of soluble or fusible glass and of baths A and B, substantially
as herein described and for the purpose stated.
In witness whereof I the said Paul Raoul de Faucheux d'Humy have
hereunto set my hand and seal this first day of February in the year of
our Lord One thousand eight hundred and eighty three.
