Improved Means for Securing the Conducting Wire to the Carbon
Electrode in Elements of Galvanic Batteries.
We, FRANZ AUGUST VON ALIMONDA, Doctor of Law, and NINO VON
ALIMONDA, Doctor of Medicine, both of Castello Alimonda, Sagrado, in the
Province of Goerz and Gradisca, Austria, 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 :-
This invention relates to a simple and reliable device for securing the conducting
wire to the carbon electrode in galvanic elements, the said device consisting in
clamping the extremity of the said wire between the carbon electrode and a
non-metallic lug fastened to the latter, in such a manner that the wire can neither
rise, nor descend, nor turn round its longitudinal axis nor move in a plane parallel
to the carbon plate.
For this purpose, the lower end of the wire is bent at right angles and projects
either into the carbon or into the lug affixed to the latter, whereas the vertical
portion of the wire is embedded in a groove preventing any lateral deviation.
In the accompanying drawing,
Figure is a perspective view of a carbon electrode to which a 'wire is secured
according to this invention.
Figure 2 shows in vertical section six different arrangements of this connection.
As shown, the lower end m of the leading wire is bent at right angles and
projects within a corresponding recess of the carbon K (Figure 2, I, IV, VI) or of
the lug B (II, III, V). The groove for the reception of the vertical portion of the
wire is cut into the carbon (II, IV) or into the lug (I, III) or half into the carbon
and half into the lug (V, VI).
After the wire has been embedded between the carbon and the lug these two
parts are secured to each other by gluing, tying, pressing, baking or any other
known process, whereby the extremity of the wire is immobilized in every
direction.
The lug B of the carbon electrode K is by preference made also of carbon ;
but it is clear that it may be formed of any other solid non-metallic material.
This device has the characteristic advantage of simplicity and cheapness and
besides allows of using only short lengths of wire for electric connections with the
carbon, thus affording the facility of effecting these connections, at a small cost, by
means of the material that is the most suitable on account of its resistance to
oxydation, viz. —platinum.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
A device for securing the conducting wire or terminal to the carbon electrode of
galvanic batteries, consisting in embedding the extremity of the wire between the
carbon (K) and a lug (B) of carbon or other known, solid, non-metallic material,
which is afterwards fastened to the carbon, the end m of the said wire being bent
at riglit angles and projecting into a recess in the carbon (Figure 2, I, IV, VI) or
in the lug (I, HI, V), the vertical portion of the said wire being embedded within a

page_text: groove cut in the carbon (II, IV) or in the lug, (I, III) or half into the carbon
and half into the lug (V, VI) substantially as described and shown.
