strasse 3, ALBERT KÖNIG, Banker, of I Elisabetlistrasse 3, CARL CAMILLE
WEINER, of I Elisabethstrasse 3, Gentleman, and Dr. ALEXANDER JORG, of
I Opernring 1, all of Vienna, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to a carbon clamp which is electrically connected to the
material forming a carbon electrode, by means of an enclosed body of mercury,
where by a reliable connection of the carbon electrode with the conducting wire is
effected, which is not injuriously affected by any corrosive vapours that may rise
up from the battery cell.
The said carbon clamp is shewn in two modifications in Figures 1 and 2 of the
accompanying drawing. The carbon electrode a is formed with an enlarged hole b
through which is passed the screw bolt d of a clamp.
The space between the bolt and the sides of the hole is filled with mercury,
the escape of which is prevented by caoutchouc plates c which are pressed against
the end surfaces of the hole. For this purpose the bolt & is provided with a
head and a screw nut de which latter, in the arrangement at Fig. 1, maintains
the conducting wire g in conducting connection with the bolt d by means of the
metal washers f.
As the electric contact between the bolt and the electrode a is effected by
means of a body of mercury which is enclosed by means of the caoutchouc discs c,
this contact cannot be injuriously affected or destroyed by any corrosive gases
or vapours that may rise up from the battery element.
In the modification shewn at Figure 2, the head of the bolt d is formed into
a terminal screw clamp of known form for securing the conducting wire.

page_text: WEINER, of I Elisabethstrasse 3, Gentleman, and Dr. ALEXANDER JORG, of
I Opernring I, all of Vienna, 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 carbon clamp which is electrically connected to the
material forming a carbon electrode by means of an enclosed body of mercury,
shut off from the outside whereby a reliable connection of the carbon electrode
with the conducting wire is effected, which is not injuriously affected by any cor-
rosive vapours or gases that may rise up from the battery cell.
.
The said carbon clamp is shewn in two modifications in Figures 1 and 2 of
the drawing accompanying our Provisional Specification. Tho carbon electrode a
is formed with an enlarged hole through which is passed the screw bolt d of a
clamp.
The space between the bolt and the sides of the hole is filled with mercury,
the escape of which is prevented by caoutchouc plates c which are pressed against.
the end surfaces of the hole. For this purpose the bolt d is provided with a
head and a screw nut which latter in the arrangement of Fig. 1 maintains
the conducting wire g in conducting connection with the bolt d by means of the
metal washers f.
As the electric contact between the bolt d and the electrode a is effected by
means of a body of mercury which is enclosed so as to be shut off from the
outside by means of the caoutchouc discs c, this contact cannot be injuriously affected
or destroyed by any corrosive gases or vapours that may rise up from the battery
element.
In the modification shewn at Figure 2, the head of the bolt d is formed into
a terminal screw clamp of known form for securing the conducting wire.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim iB:-
A carbon clamping device for insuring the electrical contact between the carbon
electrode and the conductor, consisting of a hollow such as formed in the body
of the carbon electrode and hermetically closed at each end'aud which is filled with
mercury, through a bolt such as d passing through the said hollow for effecting the
connection of the electrode with the conductor, substantially as described:
