We, ALFRED WUNDERLICH, Civil Engineer, and OTTO EISELE, Mechanician of
8 Boulevard Baudouin Brussels, in the Kingdom of Belgium, do hereby declare the
nature of this invention to be as follows
This invention relates to galvanic batteries and has for its object a battery which
shall yield a constant current.
The battery is formed as follows:
A convenient number of carbon or copper plates, preferably circular are threaded
alternately with similar zinc-plates on a shaft and secured thereon by two clamping
plates or discs of wood or other suitable material fixed one, on or over each end of the
said shaft. The shaft is journalled or otherwise revolvably supported in a frame
which supports a tank or receptacle situated above the plates and serving to contain
the exciting liquid. A second tank is placed below the plates. The zinc-plates may
be cast with raised frets on one of their surfaces of such a shape as to divide the
surface into sector-shaped compartments of suitable number. In this case, when
putting the plates together the zinc-frets are insulated by suitable packing from the
carbon plates; or a separate perforated plate of non-conducting material representing
and forming the said frets may be placed between each zinc-plate and the carbon
plate on one side of it. The frets are so contrived that the sectorial compartments
formed thereby may have one inlet and one outlet formed by two channels side by
side extending from the rim of the plates towards the centre, where they terminate in
the said sector-shaped compartments, at the apex of the latter. The upper tank is
provided below with a number of valves corresponding to the spaces in the revolving
battery. These valves are closed by conical plugs, which when drawn up, allow the
liquid to flow onto the battery. In the liquid in the tank is also a float attached by
an arm to a cam which controls the plugs, so that in proportion as the liquid and
float descend, the plugs are raised by the cam so that the opening of the valves is
proportional to the pressure of liquid, and the outflow therefore constant.
The liquid falling on the outer sector wall of one of the compartments follows this
until the entrance channel is reached when it enters this and gradually fills the
respective sector; when the weight of liquid therein is sufficient to turn the battery

the lowest sector begins to turn on its upward course, the liquid therein will flow out
into the tank below, and so on with each sector, the empty sectors, passing upward
and in due course arriving under the jets, are again filled and the process continues.
As the liquid runs low in the upper tank, it can be supplied from the lower. By this
apparatus the carbon plates will recover from the polarising effect of the solution
whilst the sectors are empty.
To receive the current, a ring of copper or brass or other metal is arranged at each
end of the shaft, in contact with the last plate of the series, a contact brush or spring
slides along each ring and carries the current to two terminals on the frame. The
contact spring may be adjusted so as to exert more or less pressure on the ring and so
control the speed of revolution of the discs. Instead of several valves in the upper
tank, one long valve may be used opening over a gutter provided with separate jets.
The accompanying drawing will show a method in which this invention may be
performed.

page_text: We, ALFRED WUNDERLICH, Civil Engineer, and OTTO EISELE, Mechanician, of
8 Boulevard Baudouin, Brussels, in the Kingdom of Belgium, do hereby declare the
nature of our 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 galvanic batteries and has for its object a battery which
shall yield a constant current.
The battery is formed as follows; a convenient number of carbon or copper plates
preferably circular are threaded alternately with similar zinc plates on a shaft and
secured thereon by two clamping plates or discs of wood or other suitable material
fixed one on or over each end of the said shaft. The shaft is journalled or otherwise
revolvably supported in a frame which supports a tank or receptacle situated above
the plates and serving to contain the exciting liquid. A second tank is placed below
the plates. The zinc plates may be cast with raised frets on one of their surfaces of
such a shape as to divide the surface into sector-shaped compartments of suitable
number. In this case when putting the plates together the zinc frets are insulated
by suitable packing from the carbon plates. Or a separate perforated plate of non-
conducting material representing and forming the said frets may be placed between
each zinc plate and the carbon plate on one side of it. The frets are so contrived that
the sectorial compartments formed thereby may have one inlet and one outlet formed
by two channels side by side extending from the rim of the plate towards the centre,
where they terminate in the said sector shaped compartment, at the apex of the latter.
The upper tank is provided below with a number of valves corresponding to the
spaces in the revolving battery. These valves are closed by conical plugs which when
drawn up allow the liquid to flow onto the battery.
In the liquid in the tank is also a float attached by an arm to a cam which controls
the plugs, so that in proportion as the liquid and float descend, the plugs are raised by
the cam, so that the opening of the valves is proportional to the pressure of liquid,
and the outflow therefore constant.
The liquid falling on the outer sector wall of one of the compartments follows this
until the entrance channel is reached when it enters this and gradually fills the
respective sector; when the weight of liquid therein is sufficient to turn the battery
the next compartment will be brought under the jets and filled and so on; as however
the lowest sector begins to turn on its upward course, the liquid therein will flow out
into the tank below, and so on with each sector, the empty sectors, passing upward
and in due course arriving under the jets, are again filled and the process continues.
As the liquid runs low in the upper tank it can be supplied from the lower. By this
apparatus the carbon plates will recover from the polarising effect of the solution
whilst the sectors are empty.
To receive the current, a ring of copper or brass or of other metal is arranged at
each end of the shaft, in contact with the last plate of the series, a contact brush or

spring slides along each ring and carries the current to two terminals on the frame.
The contact spring may be adjusted so as to exert more or less pressure on the ring
and so control the speed of revolution of the discs. Instead of several valves in the
upper tank, one long valve may be used opening over a gutter provided with
separate jets.
The drawing filed with our provisional specification will show a method in which
this invention may be performed.

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 :-
1. Electrode-discs Z and K separated from each other by ribs M so as to form
between each two discs canals op and chambers N¹ to N° in combination with
reservoir E, substantially as and for the purpose set forth.
2. For the purpose of regulating the flow of the liquid from the reservoir E of a
valve F which is opened more or less by an eccentric, when the float L connected with
said eccentric sinks.
3. The gutter with tubes m, which gutter is made adjustable and kept filled on its
whole length through the funnel tube b.
4. The slide springs R for receiving the current, and serving at the same time to
regulate the rotary speed of the electrode discs, by pressing them more or less strongly
onto the brass tube A¹ serving as current accumulator, by displacing the levers S,
between the set screws u u¹.
