265 Victoria Park Road London N.E. EMILE ROUSSEAU Electrician 3 Knotts Green
Leyton Essex, Conrad Krauss FALKENSTEIN, electrical engineer 265 Victoria Park
Road, London, N.E. do hereby declare the nature of this invention to be as
follows:-
Electric Light Fittings of Vulcanite or other insulating material with the leads
inserted, and covering same with metal.
Our improvements consist in the construction of Electric Light fittings combining
lightness with high insulation of the leads, carrying the electric current to lamps
through Electroliers, brackets, etc., also applicable to other purposes where electric
currents have to be conveyed.
In carrying out our improvements we insulate the wires in the following manner;
riz., A core of vulcanite or other suitable insulating material is taken, and grooves are
cut or moulded along it to receive the wires or leads, the core, with the wires-which
may be bare or covered-laid in the grooves is now drawn into a closely fitting tube
of vulcanite or other insulating material, the whole can now be bent to any required
shape, and then built up into electroliers, brackets, table lamps, portable standards, etc.
the tubes may also be used for mains, which can be made into any lengths, screwed
together by unions which can be made air and water tight, the said tubes etc. after
being formed or built up into electroliers, brackets, etc. may be electrically or otherwise
covered with metal to any desired thickness.

COMPLETE SPECIFICATION.
Improvements in Electric Light Fittings and Conductors.
We, CHARLES KRAUSS FALKENSTEIN, Electrician and India rubber Manufacturer of
265 Victoria Park Road, London N.E. EMILE ROUSSEAU Electrician 3 Knotts Green,
Leyton Essex, CONRAD KRAUSS FALKENSTEIN, Electrical Engineer, 265 Victoria
Park Road, London N.E. do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
Electric light fittings of vulcanite or other insulating material with the leads
inserted, and covering same with metal.
Our improvements consist in the construction of electric light fittings combining
lightness with high insulation of the leads, carrying the electric current to lamps
through Electroliers, brackets, &c. also applicable to other purposes, where electric
currents have to be conveyed.
In carrying out our improvements we insulate the wires in the following manner;
riz. a core of vulcanite or other suitable insulating material is taken, and grooves are
cut or moulded along it to receive the wires or leads, the core, with the wires which
may be bare or covered, laid in the grooves, is now drawn into a closely fitting tube
of vulcanite or other insulating material, the whole can now be bent to any required
shape and then built up into Electroliers, brackets, table lamps, portable standards &c.,
the tubes may also be used for mains, which can be made into any lengths, screwed

page_text: together by unions which can be made air and water tight, the said tubes &c. after
being formed or built up into Electroliers brackets &c. may be electrically or otherwise
covered with metal to any desired thickness, and finished in any style this outer plated
vulcanite tube can also be used for gasaliers, gas brackets &c.
Fig. 1 of the accompanying drawings is a transverse section and Fig. 2 is a
longitudinal section shewing two conducting wires W (which may he bare or covered
with insulating material) laid in the grooves of a core C of vulcanite or other suitable
insulating material, the whole enclosed in a tube T of similar material. Obviously
there be a greater number of grooves in the core to accommodate a greater number of
wires.
:
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is
An insulated conductor for two or more wires consisting of a core having grooves in
which the wires are laid and a tube covering the core and wires.
