PROVISIONAL
SPECIFICATION.
Improved Joint for Telegraph and other Wires Conveying Electricity.
I, HARRY WILLIAM NEILD, of 89, Blackheath Road, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
The joint is made by passing the ends of the two wires to be joined, through
a tube or sleeve of suitable size, which has near the centre about half the section
cut away, thus exposing the two wires to be joined at this part of the sleeve.
When the wires are taut, the ends are bent over, thus keeping them in position,
while the joint is made absolute by soldering or brazing the wires together.
through the opening in the sleeve. For example
To join copper telegraph wires, the tube or sleeve is made of copper tube, or
tube of its alloys, oval in shape, just large enough to take the wires side by side,
and the opening at the centre of the sleeve is made through one of its flatter
sides. By preference the sleeve is previously tinned inside with a suitable solder.
Heat is then applied by soldering iron or other well known means with suitable
solder to the wires where they are exposed through the opening in the sleeve,
and the two wires are thus joined in sight of the operator. This avoids the
uncertainty, which must always occur where joints are made in sleeves in a con-
tinuous tube, where the result of the soldering process is hidden from view. It
also enables the joint to be made in the centre of the sleeve (or joint) where the
wires overlap, and the heat applied to effect the soldering is thereby prevented
from affecting the main wires, and weakening them by their being made soft by
the heat applied, and only the joint (where the wires are double) is so affected.
Iron, steel, or aluminium wires can be joined in the same manner, but require
somewhat different treatment in making the joint.
For iron or steel wire the ends at least should be previously cleaned or treated
by the ordinary galvanizing process, and the sleeves should also be so treated
inside, whether they be of copper (or its alloys), steel or iron, and the joint should
be made by heating through the open part of the sleeve and joining the wires
with a solder principally composed of zine which will adhere to the cleaned or
galvanized parts of the wires and the sleeve previously treated as above.
Aluminium wire can be joined in very much the same manner using either
sleeves of aluminium, iron, steel, or copper (or its alloys), but by preference the
solder of zinc should be alloyed with a small proportion of aluminium.
Although satisfactory joints can be made as above described by using sleeves
of a different metal to the wire to be joined, it is preferable to use a sleeve of
the same metal as the wire.

I, HARRY WILLIAM NEILD, of 89, Blackheath Road, in the County of Kent,
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 joint is made by passing the ends of the two wires to be joined, through
a tube or sleeve of suitable size, which has near the centre about half the section
cut away, thus exposing the two wires to be joined at this part of the sleeve.
When the wires are taut, the ends are bent over, thus keeping them in position,
while the joint is made absolute by soldering or brazing the wires together,
through the opening in the sleeve.
Figure 1 is a plan, Figure 2 a side elevation, and Figure 3 an end elevation of
the sleeve. Figure 4 is a plan of the completed joint.
a is the sleeve of oval section just large enough to receive the wires b side by
side and the opening at the centre of the sleeve is made through one of its flatter
sides. c is solder filling the interstices between the wires b and the tube a.
To join copper wires the sleeve is of copper or its alloys preferably tinned inside
with a suitable solder. Heat is then applied by soldering iron or other well
known means with suitable solder to the wires where they are exposed through
the opening in the sleeve, and the two wires are thus joined in sight of the
operator.
For iron or steel wire the ends at least should be previously cleaned or treated
by the ordinary galvanizing process, and the sleeves should also be so treated
inside, whether they be of copper (or its alloys), steel or iron, and the joint should
be made by heating through the open part of the sleeve and joining the wires
with a solder principally composed of zinc which will adhere to the cleaned or
galvanized parts of the wires and the sleeve previously treated as above.
Aluminium wire can be joined in very much the same manner using either
sleeves of aluminium, iron, steel, or copper (or its alloys), but by preference the
solder of zinc should be alloyed with a small proportion of aluminium.
Although satisfactory joints can be made as above described by using sleeves
of a different metal to the wire to be joined, it is preferable to use a sleeve of
the same metal as the wire.
When there is any strain on the wires to be joined as is the case with air lines
the ends of the wires after being passed through the sleeve a are bent as shown
at Figure 4 which not only strengthens the joint but takes the strain whilst
the joint is being made.
The use of this invention avoids the uncertainty which must always occur where
joints are made in sleeves in a continuous tube, where the result of the soldering
process is hidden from view. It also enables the joint to be made in the centre
of the sleeve (or joint) where the wires overlap, and the heat applied to effect the
soldering is thereby prevented from affecting the main wires, and weakening them
by their being made soft by the heat applied, and only the joint (where the wires
are double) is so affected.
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. A sleeve open at one side for part of its length and coated internally with
solder.
2. The combination of a sleeve open at one side for part of its length two con-

page_text: ductors lying side by side in the sleeve and solder filling the interstices between
the conductors and the sleeve.
3. The combination of a sleeve open at one side for part of its length two con-
ductors lying side by side in the sleeve their ends protruding beyond the sleeve
and being bent at an angle to their length and solder filling the interstices
between the conductors and the sleeve.
4. Joints for electric conductors substantially as described and illustrated in the
drawings.
