page_text: Improvements in or connected with Electrical Conductors.
I, HENRY EDMUNDS, of 39, Victoria Street, in the City of Westminster, Electrical
Engineer, do hereby declare the nature of my invention to be as follows:-
My invention has for its object to provide electrical conductors which are adapted
for use in situations where it is convenient or permissible only to employ a single
line, but where it is desirable to have a return wire; the invention also providing a
conductor which is protected against injury. The conductor according to my
invention consists of a wire, or wires, insulated by any suitable insulating material
and then covered with lead, or lead alloy, or the like, and then over this is applied
copper, or other conductive metal, which is to act as the return line and this, if
desired, may in turn be insulated. If the conductor is to have an ornamental
appearance the outer tube may be made of gold, silver, or other ornamental metal,
which will afford a protection against oxidation or other injury.
The outer tube or covering may be conveniently applied to the lead or the like by
electro-deposition, and a very thin coating will answer the purpose of protection.
The tube however, where the coating is to be used as a return line, is of a thickness
in accordance with the current which it is to carry. Although I have stated that the
inner conductor is for the feeding line and the outer tube for the return line this
may of course be reversed if desired.

I, HENRY EDMUNDS, of 39, Victoria Street, in the City of Westminster, Electrical
Engineer, 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 :-

a conductor which is protected against injury. The conductor according to my inven-

The outer tube, or covering, may be conveniently applied to the lead, or the like,

The tube, however, where the coating is to be used as a return line, is of a thickness
in accordance with the current which it is to carry. Although I have stated that the
inner conductor is for the feeding line and the outer tube for the return line this may
of course be reversed if desired.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An electrical conductor provided with an inner conductor insulated and covered
with lead, lead alloy, or the like and then with an outer conductor as hereinbefore
described.
2. An electric conductor provided with an inner conductor insulated and covered
with lead, lead alloy or the like to which is applied a coating or electro-deposit of gold,
silver or the like as hereinbefore described.
3. An electric conductor consisting of or comprising an inner conductor covered
by insulation, and then by lead, lead alloy or the like which has a coating or covering
of a conductive metal protected by insulation as herein before described.
