Improvements in or relating to Electric Accumulators.
I, PETER LAUBER, of Fasanenweg 40 Basle, in the Republic of Switzerland,
Technical Electrician do hereby declare the nature of this invention to be as
follows:-
The spread and sale of electric power by means of accumulators are checked on
account of their effecting too low an electromotive force in comparison with the
intensity of the current. The use of these accumulators is therefore mostly
confined to a great number of cells, or in other words: the commercial value of
electricity depends on the possibility of storing the electric current in any desirable
proportion of volts to ampères. This is possible with a high electric power without
taking a surplus of energy into the bargain; to do this with a small power is a
matter of impossibility.
"
The Elektrothek is a kind of secondary pile with which any proportion of
volts to ampères can be obtained. It is a derivation of a Voltaic or a Zambonic
pile, of an Elster and Gertel's pile, and it connects them with the accumulators
used at the present date.
The electrodes are made of metallic plates which are impenetrable for fluids.
On their surfaces they have deepenings or cavities of any shape, into which the
active material is put. The electrolyte is shut in between the electrodes in such a
manner that the electrolyte on one side of the electrode has no contact with the
electrolyte on the other side. The electrodes are placed at a suitable distance
from each other by means of an insulating substance. They have electrical
connexion only by the conductivity of the electrolytes. The electrodes and the
insulating interpositions are fastened together in a suitable manner. The first and
the last plates only have each a metallic lame, serving as conductors of the
pile. These two plates have only one polarity, as they are only on one side in
contact with the electrolyte all the other plates have two polarities, as both sides
of them touch the electrolytes which cannot join or unite.

and the last plate P, will be negative.
The number of the electrodes may be eventor odd; it depends on the electro-
motive force which is required from the Elektrothek.” The size of the, electrodes
depends on the required intensity of the current.
As the connecting pieces between the different plates are omitted, and as there is
a possibility of storing the whole power with a few Elektrotheks or even a single
one, it is evident, that, in order to have the same effect as any storage-battery
hitherto in use, the Elektrothek has the advantage of being lighter and smaller
than any other accumulator.
The Elektrothek" is therefore of high value as a motive force of automatic
vehicles and of illuminations in a small style.

Improvements in or relating to Electric Accumulators.
I, PETER LAUBER of Basle in the Republic of Switzerland, 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 spread and sale of electric power by means of accumulators are checked on
account of their effecting too low an electromotive force in comparison with the
intensity of the current. The use of these accumulators is therefore mostly
confined to a great number of cells, or in other words; the commercial value of
electricity depends on the possibility of storing the electric current in any desirable
proportion of volts to ampères. This is possible with a high electric power without
taking a surplus of energy into the bargain; to do this with a small power is a
matter of impossibility.
The "
Electrothek is a kind of secondary pile with which any proportion of
volts to ampères can be obtained. It is a derivation of a Voltaic or a Zambonic
pile, of an Elster and Gertels pile, and it connects them with the accumulators used
at the present date.
The electrodes are made of metallic plates which are impenetrable for fluids.
On their surfaces F they have deepenings or cavities of any shape, into which the
active material is put. The electrolyte is shut in between the electrodes in such a
manner, that the electrolyte on one side of the electrode has no contact with the
electrolyte on the other side. The electrodes are placed at a suitable distance
from each other by means of an insulating substance J. They have electrical
connection only by the conductivity of the electrolytes. The electrodes and the
insulating interpositions J are fastened together in a suitable manner. The first
and the last plates only have each a metallic lame serving as conductors of the pile.
These two plates have only one polarity, as they are only on one side in contact
with the electrolyte; all the other plates have two polarities, as both sides of them
touch the electrolytes which cannot join or unite.
Let the first plate be P.

and the last plate P, will be negative.
The number of the electrodes may be even or odd; it depends on the electro-
motive force which is required from the "Electrothek." The size of the electrodes
depends on the required intensity of the current.
As the connecting pieces between the different plates are omitted, and as there is
a possibility of storing the whole power with a few Electrotheks or even a single
one, it is evident, that, in order to have the same effect as any storage-battery
hitherto in use, the Electrothek has the advantage of being lighter and smaller
than any other accumulator.
The Electrothek" is therefore of high value as a motive force of automatic
vehicles and of illuminations on a small scale.
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 :-
1. A storage battery in which the electrolytes are separated by the electrodes
substantially as described.
2. A storage battery in which the electrodes are insulated from each other and
electrically connected only by the electrolytes.
3. A storage battery in which the electrodes are connected only by the
electrolytes and the electrolytes are separated by the electrodes.
4. The storage battery substantially as described and illustrated in the accom-
panying drawings.
