I HENRY EDMUNDS of 39 Victoria Street in the City of Westminster Electrical
Engineer do hereby declare the nature of this invention to be as follows :—
The object of my invention is to provide an Improved Electrical Conductor for
use for conveying current to objects moving in contact therewith. For instance
for electric tramways such conductors as hitherto employed have consisted of an
overhead single solid wire or rod of a thickness sufficient for the required current.
Such wire or rod owing to its thickness does not possess the flexibility which is
desirable in such conductors. It has hitherto not been found practicable to
employ a conductor made up of a number of wires as owing to the wear which
takes place on one side of the conductor the wires which are situated on that side
become worn through and the strands or individual wires then become dismembered
or separate from the others. It is the object of my invention to provide a con-
ductor which presents the desired flexibility and which at the same time will allow
of wear without the component members of the conductor becoming separated from
the main body of the conductor. According to my invention I compose the
conductor of wires or strips (I will presume them to be wires) of copper or other
conductive metal which I interweave plait or interlace in such a manner that they
are interlocked with each other so that adjacent wires at short intervals of their
length serve mutually to bind or retain each other in place in such a way that
should portions of the wires become worn through the remaining parts of the wires
will still be retained in place by the adjacent wires interlocking therewith. I may
for some purposes after the wires have been combined as aforesaid subject the
conductor to compression which may be effected between rolls or in any other
suitable way so as to at one or at several operations compress and reduce the
conductor to the required cross sectional shape and compactness.

COMPLETE SPECIFICATION.
Improved Electrical Conductor.
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:-
The object of my invention is to provide an Improved Electrical Conductor for
use for conveying current to objects moving in contact therewith. For instance
for electric tramways such conductors as hitherto employed have consisted of an
overhead single solid wire or rod of a thickness sufficient for the required current.
Such wire or rod owing to its thickness does not possess the flexibility which is
desirable in such conductors. It has hitherto not been found practicable to
employ a conductor made up of a number of wires as owing to the wear which
takes place on one side of the conductor the wires which are situated on that side
become worn through and the strands or individual wires then become dis-
membered or separate from the others. It is the object of my invention to provide
Price 8d1

page_text: a conductor which presents the desired flexibility and which at the same time will
allow of wear without the component members of the conductor becoming
separated from the main body of the conductor. According to my invention as
shewn for example by the accompanying drawing which represents a face view of a
portion of a conductor constructed according to my invention I compose the
conductor of wires or strips a (I will presume them to be wires) of copper or other
conductive metal which I interweave plait, interlace or combine in such a manner
that they are interlocked with each other so that adjacent wires at short intervals
of their length serve mutually to bind or retain each other in place in such a way
that should portions of the wires become worn through or broken as shewn for
example at a the remaining parts of the wires will still be retained in place by the
adjacent wires interlocking therewith. I may for some purposes after the wires
have been combined as aforesaid subject the conductor to compression which may
be effected between rolls or in any other suitable way so as to at one or at several
operations compress and reduce the conductor to the required cross sectional shape
.and compactness.
I do not claim a wire rope or conductor laid in the way in which wire ropes
have been hitherto made in which the wires are coiled in such a manner that when
they become worn through or broken the wires will uncoil neither do I restrict my
invention to the interlocking arrangement of the wires shewn in the accompanying
drawing as the said wires may be otherwise combined so that such conductors will
have their component wires so disposed that they mutually overlap each other at
short intervals or partially overlap each other or interlock with each other at short
intervals throughout their length so that when they become worn through or
broken they will still be held in place by the adjacent wire or wires.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
.claim is :-
1. An electrical conductor for conveying current to objects moving in contact
therewith the said conductor being composed of wires or strips of copper or other
conductive metal plaited interlaced or interwoven in the manner and for the
purpose herein before explained.
2. An electrical conductor for conveying current to objects moving in contact
therewith the said conductor being composed of wires or strips of copper or other
conductive metal plaited interlaced or interwoven in the manner and for the
purpose herein before described and afterwards subjected to compression.
