PROVISIONAL SPECIFICATION.
Improvements in Electrical Conductors, and in the Method of
Making Connections between 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:-
The object of my invention is to provide means whereby connections between
electrical conductors can be made with great facility and in a very efficient manner.
According to my invention the conductor being composed of a number of members
such as wires or strips connection is conveniently made by severing one or more
of the said members from the main body and connecting the member so severed
to another conductor so that the said member constitutes a connection for the
passage of electricity between the conductors so connected. This method of
connection can advantageously be applied to various arrangements of conductors
or where electrical connection is to be made between a conductor and any other
conductor or object for example it can be applied to electrical railways or
tramways where electrical connection is to be established between the lengths of
rails and a conductor supplementary to the rails. In this case the supplementary
conductor composed of several members may be laid between the rails and at the
requisite intervals a member severed as aforesaid be led from the said conductor
and connected alternately to the lengths of rails on either side. In order to guard
against the separation of any portion of the conductor entirely from the conductor
by severance of the same member at two points 1 weld or otherwise connect the
members of the conductor together at such intervals in the length of the conductor
as will allow the necessary length of the member to form the connection being led
therefrom. When the conductor from which the severed member is to be led is
covered with an insulating material a slit can be made therein corresponding to the
length of the member to be led therefrom and the member being severed is drawo
from the said slit and connected to the conductor or article with which electrical
connection is to be made and the portion of the member thus withdrawn can be
covered by insulating material and the slit be closed with insulating material to
make good the insulation of the conductors as a whole.

page_text: Improvements in Electrical Conductors, and in the Method of
Making Connections between Electrical Conductors.
I, HENRY EDMUNDS of 39 Victoria Street in the City of Westminster,.
Electrical Engineer do hereby declare the nature of my 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 means whereby connections between
electrical conductors can be made with great facility and in a very efficient
manner.
According to my invention the conductor being composed of a number of
members such as wires or strips, connection is conveniently made by severing one
or more of the said members from the main body and connecting the member so
severed to another conductor so that the said member constitutes a connection for
the passage of electricity between the conductors so connected. This method of
connection can advantageously be applied to various arrangements of conductors
or where electrical connection is to be made between a conductor and any other
conductor or object for example it can be applied to electrical railways or tramways
where electrical connection is to be established between the lengths of rails and a
conductor supplementary to the rails, and this is the arrangement shewn in the
drawing where c are the rails. In this case the supplementary conductor a
composed of several members may be laid between the rails c and at the requisite
intervals a member severed as aforesaid be led from the said conductor and
connected alternately to the lengths of rails c on either side. In order to guard
against the separation of any portion of the conductor entirely from the conductor
by severance of the same member at two points I weld or otherwise connect the
members of the conductor together at such intervals in the length of the conductor
as will allow the necessary length of the member to form the connection being led
When the
therefrom. These portions so welded or connected are indicated at d.
conductor from which the severed members are to be led is covered with an
insulating material slits can be made therein corresponding to the length of the
members to be led therefrom and the members being severed are drawn from the
said slits and connected to the conductor or article or conductors or articles with
which electrical connection is to be made and the portion of the members thus
withdrawn can be covered by insulating material and the slits be closed with
insulating material to make good the insulation of the conductors as a whole.
For the sake of clearness however the insulating material is not shewn in the
drawing. Where it is not convenient to detach the members of the conductor
as described I may attach to the main conductor by welding or fusion or the like
separate connecting conductors which while in each case being free at each of its
ends shall be so solidly attached to the main conductor by the welding fusion or the
like that a complete homogeneous connection is formed therewith thus rendering
the connection of each separate connecting conductor absolute and complete in
itself and in no way detracting from the electrical continuity of the main conductor.
The connection of the ends of the members to the rails or other conductors may
be effected in any convenient way for example by passing each end through a slot
in a copper rivet and passing the bolt or rivet through a hole in the web of the rail
or in other conductor and rivetting over the end of the bolt or rivet together with
the end of the member so passed into the slot or by forming the end of the member
into a spiral or coil and placing this in a hole in the web of the rail or in other
conductor and pressing this out by means of an expander to give good electrical
contact.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what I
claim is :
1. An arrangement of electrical conductors formed or constructed substantially
as herein before described and illustrated.
2. In electrical conductors a main conductor formed of members connected at
intervals by welding fusion (or the like) and having members for making connection
severed therefrom at intervals between the welded or fused portions and attached
to other conductors substantially as herein before described.
3. Electrical conductors consisting of a main conductor composed of members
with other members welded fused or similarly connected thereto and led therefrom
and joined to other conductors substantially as hereinbefore described.
