I, OSKAR BEHREND, of 67, Unterlindau, Frankfort-on-Maine, in the Empire
of Germany, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide means for producing from alternating
electric current generators continuous current effects such as are necessary for
example for charging electric accumulators or for purposes of electrolysis.
I will describe an application of the invention to the charging of accumulators.
The accumulators to be charged are divided into two groups between which are
the terminals by which they are connected to one pole of the alternating current
generator. The outer terminals of the accumulator groups are connected to the
other pole of the generator each through a contact device, each such device consist-
ing of a fixed contact and a moveable contact the moveable contacts being provided
each with a spring tending to make the contacts and each with an armature in
proximity to one of two electro-magnets, inserted in a shunt circuit across the
poles of the alternating current machine.
As the electro magnets are polarised, every second impulse only will act upon
each one of the armatures of the moveable contacts so that at each alternate impulse
the one electro-magnet is excited and attracts its armature and removes the corre-
sponding contact. The current then passes through the other contact and through
one group of the accumulator. During the other impulses the other electro-magnet
is excited and consequently removes the contact before made and the current then
passes through the other contact and the second group of the accumulator.
Thus from the alternating current of the generator each group of the accumulator
receives only current which passes in one direction.

in and by the following statement:
The object of this invention is to provide means for producing from alternating
electric current generators continuous current effects such as are necessary for
example for charging electric accumulators or for purposes of electrolysis.
I will describe an application of the invention to the charging of accumulators,
which is shewn diagrammatically in the accompanying drawing.
The accumulators to be charged are divided into two groups A and B between
which are the inner terminals meeting at a by which they are connected to one
pole of the alternating current generator C. The outer terminals 6 of the
accumulator groups are connected to the other pole of the generator C each
through a contact device each such device consisting of a fixed contact c c and a
moveable contact d d' the moveable contacts being provided each. with a spring g g¹
tending to make the contacts and each with an armature e e¹ in proximity to one
of two electro-magnets FF inserted in a shunt circuit across the poles of the
alternating current machine.
As the electro-magnets are polarised, every second impulse only will act upon
each one of the armatures of the moveable contacts so that at each alternate
impulse the one electro-magnet is excited and attracts its armature and removes the
corresponding contact. The current then passes through the other contact and
through one group of the accumulator. During the other impulses the other electro-
magnet is excited and consequently removes the contact before made and the
current then passes through the other contact and the second group of the
accumulator.
Thus from the alternating current of the generator each group of the accumulator
receives only current which passes in one direction.
The said apparatus may also be used for feeding electrolytical baths from
alternating currents.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
An apparatus for producing from alternating current generators continuous
current effects such as are necessary for example for charging electric accumulators
or for purposes of electrolysis consisting of a supplementary circuit, spring contacts,
and electromagnets regulating these contacts substantially as and for the purposes
set forth.
