PROVISIONAL SPECIFICATION.
An Improvement in the Electrodes of Electric, Galvanic, and
other Batteries.
I, ALFRED WILLIAM ARMSTRONG, of 33 Chapter Road, Willesden Green,
in the County of Middlesex, Electrical Engineer, do hereby declare the nature
of this invention to be as follows :-
My invention relates to an improvement in the electrodes of electric galvanic
and other batteries and has for its object to prevent them from breaking and
deteriorating as has hitherto been the case.
It is a well known fact that the insulated wires fixed to electrodes constantly
break off at the joint or are corroded by the exciting fluid on account of the
plastic material not adhering to the joint, thus causing an interruption in the
working of the battery and necessitating the removal of the electrode and its
substitution by another, or the repairing of the former. Now my invention has
for its object to remedy this defect; and, I accordingly provide a cap of any
suitable shape made of brass or the like. This cap is placed over the joint
between the insulated wire and the body of the electrode, so as to protect this
otherwise weak part and hold the wire firmly in position. The hollow part of the
cap may be filled with any suitable plastic material thereby securing a double
protection to the wire exposed. The cap is then milled down to the insulated
wire by any suitable milling tool.

COMPLETE SPECIFICATION.
An Improvement in the Electrodes of Electric, Galvanic, and
other Batteries.
I, ALFRED WILLIAM ARMSTRONG, of 33 Chapter Road, Willesden Green, in
the County of Middlesex, 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 relates to an improvement in the electrodes of electric, galvanic
and other batteries and has for its object to prevent them from breaking and
deteriorating as has hitherto been the case.
In the accompanying drawings
Figure 1 is a view of an electrode provided with my improvement
Figure 2 being a separate view of the cap hereinafter referred to.
It is a well known fact that the insulated wires fixed to electrodes constantly
break off at the joint or are corroded by the exciting fluid on account of the
plastic material not adhering to the joint thus causing an interruption in the
working of the battery and necessitating the removal of the electrode and its
substitution by another, or the repairing of the former.
Now my invention has for its object to remedy this defect; and, I accordingly
provide c preferably of the shape shown in Figure 2 and made of brass or other
01

page_text: suitable material. This cap is placed as shown in Figure 1 over the joint between
the insulated wire w and the body E of the electrode, so as to protect this
otherwise weak part and hold the wire firmly in position.
The hollow part of the cap may be filled with any suitable plastic material
thereby securing a double protection to the wire exposed. This cap is then
milled down to the insulated wire as shewn in Figure 1, by any suitable milling
tool.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In the electrodes of electric, galvanic and other batteries, the cap c substantially
as herein described and shown and for the purposes set forth.
