PROVISIONAL SPECIFICATION.
Improvements in the Formation of Solid Ends on Flexible or
Compound Electrical Conductors.
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:-
My invention has for its object to form solid ends on flexible compound
conductors and is more especially intended for application to conductors which are
to be used for armature windings.
According to my invention metal (which should be of the same kind as that of
which the wires or strips are composed) is applied at the requisite temperature to
the ends of the wires or strips. This is most conveniently effected by introducing
the ends of the wires or strips to be connected into a mould of the form and size
which the solid ends are to have and introducing molten metal into this mould.
Dated this 11th day of February 1893.

COMPLETE SPECIFICATION.
Improvements in the Formation of Solid Ends on Flexible or
Compound Electrical Conductors.
I HENRY EDMUNDS of 39 Victoria Strect 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:-
My invention has for its object to form solid ends on flexible compound
conductors and is more especially intended for application to conductors which are
to be used for the armatures of dynamo electric machines.
According to my invention metal (which should be of the same kind as that of
which the wires or strips are composed) is applied at the requisite temperature to
the ends of the wires or strips. This is most conveniently effected by introducing
the ends of the wires or strips to be connected to an extent necessary to ensure
firm connection into a mould of the form and size which the solid ends are to have
and introducing molten metal into this mould.
The accompanying drawings illustrate forms of conductors made according to my
invention.
a is the part of the conductor made of compound strands of wires or strips as
hereinbefore described and bare the solid ends.
Figure 1 is a side view and end view of a rectangular or flattened compound
conductor before the solid ends are applied. The other figures shew the conductors
with the solid ends applied.
Figure 2 shews in side elevation and end views a square conductor with a plain
solid end and with the other end formed with a reduced mid-tongue.
Figure 3 shews in side elevation and end views a rectangular or flattened
conductor with a mid-tongue at one end and with a side tongue at the other end.
Figure 4 shews in side elevation, plan and end views a rectangular or flattened
conductor with one end forked and the other end pierced by a hole.
Figure 5 shews in side elevation and end views a square conductor with plain
solid ends having collars at b³.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
Flexible or compound electrical conductors provided with solid ends in the
manner herein before described.
