Improved Controlling Apparatus for Accumulator Batteries.
We, GEORG JACOB ERLACHER and MICHELE ANGELO BESSO, both of Schaffhauser-
strasse 5, Winterthur, in the Republic of Switzerland, Gentlemen, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a novel controlling apparatus for the cutting in and
out of the elements of a battery of accumulators which apparatus presents the
advantage in comparison with the similar apparatuses hitherto known, of requiring
fewer connections between the accumulators and the apparatus, because reductions
are possible by the charging and discharging of the elements.
in
The invention is shown diagrammatically in the accompanying drawings.
In Figure 1 the invention is shown applied to a simple current controller, and
Figure 2 to a double apparatus.
Of the eleven elements 2¹ to 211 of an accumulator battery shown in Figure 1,
the five first elements 21 to 5 are connected to the insulated conductors cl to ch
and C¹ to C in such a manner, that between the contact pieces c¹ and C¹, c² and C²

of the other six elements 26 to z¹ are connected. Upon the displacement of the
contact shoe S placed movably upon a spindle and provided with the two contact
springs F F insulated there upon, the springs upon the contacts and the bars first
establish electric communication between s¹ and c¹ up to c and then between $2
and C¹ to C6.
At this motion of the shoe the elements of the group z¹ to are cut in one after
the other into the current circuit and consequently there is also obtained a pro-
gressing regulation of the tension thereof. Upon the transfer from s¹ to $2 and
from co to C¹ the same graduation is obtained, because, although the five elements z¹
to are cut off from the current circuit, on the other hand at the same moment
the elements 26 to 211 are cut in. If the slide be moved further from C', the first

the number of elements of the undivided group and by corresponding adjustment
of the number of not divided groups, the number of the regulating elements can
be altered at will.
In order to prevent short circuiting of single elements during the transfer from
one contact piece to another, the spring F is divided and provided with a little
resistance, which in the said moment is cut in so as to weaken the current of the
respective element.

page_text: In Figure 2 the new method of control is applied to a double controlling
apparatus.
Both with the machine and also with the main conductor there is connected a
controlling apparatus with the contacts c¹ to co and C¹ to C. The similarly named
contacts are mutually connected and the elements z¹ to 25 are connected thereto.
Consequently c¹ and "C¹ are connected with the element z¹, and c² C² are connected
with the element 22, whilst the group of elements placed at the other end of the
battery 26 to 21 is connected on the one hand to the two contact bars 2. The main
conductor is connected to the two bars 3 st and the machine to the two bars 5 s.
The bars 35 56 are conductors throughout their whole length and lie parallel
to the contact rows c¹ to C6 and the bars s¹ $2.
The contact shoes adjustable by means of screw spindles are provided with
contact springs f¹ 2 which are connected together in the usual manner through
resistances. It will be seen from the drawing that the two controlling apparatuses
are independent the one of the other, and that the one admits of the regulation of
the supply circuit and the other of the current consuming circuit.
In the position
of the shoes shown in Figure 2 the lighting current goes through all elements
excepting 21 22 23, whilst the elements 21 22 23 and 26 to 2" are shut out from the
machine current. The lighting current passes from 26 to the bar s from that to
the bar 3, then to the lamps and through the bar s, the contact back to the
element. The machine current passes over the bar so to the bar s2 and into the
element 12 of the battery, which it quits after flowing through element in order
to return over C+ and the bar to the machine. By moving backwards and for-
wards of the two contact shoes the number of the elements included in each current
circuit can be altered in the same manner as already described with regard to
Figure 1.

Improved controlling Apparatus for Accumulator Batteries.
We, GEORG JACOB ERLACIER and MICHELE ANGELO BESSO, both of Schaffhauser-
strasse 5, Winterthur, in the Republic of Switzerland, Gentlemen, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a novel controlling apparatus for the cutting in and
out of the cells either simply or by sections of a battery of accumulators. My
improved apparatus presents the advantage in comparison with the similar
apparatuses hitherto known, of requiring fewer connections between the accumu-
lators and the apparatus.
The invention is shewn diagrammatically in the drawings filed with the Pro-
visional Specification.
in
In Figure 1 the invention is shown applied to a simple current controller, and
Figure 2 to a double apparatus.
Of the eleven elements 21 to z 11 of an accumulator battery shewn in Figure 1,
the first five elements z 1 to z 5 are connected to the insulated conductors c 1 to c6
and C1 to C6 in such a manner, that between the contact pieces cl and C1,

page_text: c2 and C2 and so forth a conducting connection is formed. These rows of con-
tacts have opposite to them two bars s 1 s2 insulated from one another, to which
bars the connections of the other six elements 26 to z 11 are connected.
Upon the
displacement of the contact shoe S placed movably upon a spindle and provided
with the two contact springs F1 F2 insulated thereupon, the springs upon the contacts
and the bars first establish electric communication between 1 and c 1 up to € 6
and then between s 2 and C1 to C 6.
S
By this movement of the shoe the elements of the group z 1 to z5 are cut in
one after the other into the current circuit and consequently there is also obtained
a progressive regulation of the voltage supplied thereto. Upon the transfer from s 1
to s 2 and from c6 to C1 the same graduation is obtained, because, although the
five elements 21 to 25 are cut off from the current circuit, on the other hand at
the same moment the elements z 6 to 11 are cut in. If the slide be moved further
from C', the first elements z2 to 25 are successively again çut in,
The number of the graduations of voltage in the arrangement illustrated amounts
to eleven, whilst only seven connections between the groups of elements and the
controlling apparatus are requisite. Consequently there are required in this device
four connections less than there are in the arrangements hitherto in use. By
suitably choosing the number of elements of the undivided group and by corres-
ponding adjustment of the number of undivided groups, the number of the regu-
lating elements can be altered at will.
In order to prevent short circuiting of single elements during the transfer from
one contact piece to another, the spring F2 is divided and provided with a little
resistance, which at the time of transfer is cut in so as to weaken the current of the
respective element.
In Figure 2 the new method of control is shewn applied to a double controlling
apparatus.
Both with the machine and also with the main circuit conductors there is connected
a controlling apparatus with the contacts c 1 to c6 and C1 to C6. The similarly
named contacts are mutually connected and the elements z 1 to 25 are connected
thereto. Consequently c1 and C1 are connected with the element z 1, and c2 02
are connected with the element z 2, whilst the group of elements placed at the
other end of the battery 6 to z 11 is connected on the one hand to the two contact
bars s 2. The main conductor is connected to the two bars s3 s4 and the machine
to the two bars s5 s 6. The bars s3 s4 s5 s6 are conductors throughout their
whole length and lie parallel to the contact rows c1 to C6 and the bars s 1 s 2.
The contact shoes adjustable by means of screw spindles are provided with con-
tact springs f1 f2 which are connected together in the usual manner through
resistances. It will be seen from the drawing that the two controlling apparatuses
are independent the one of the other, and that the one admits of the regulation of
the supply circuit and the other of the current consuming circuit. In the position
of the shoes shewn in Figure 2 the lighting current goes through all elements
excepting 12 23, whilst the elements 1 2 3 and 6 to 11 are shut out
from the machine current. The lighting current passes from z 6 to the bar s 1, from
that to the bar s 3, then to the lamps and through the bar s4, and the contact c4
back to the element 4. The machine current passes over the bar s 6 to the bar s2
and into the element z 12 of the battery, which it quits after flowing through
element z4 in order to return over C4 and the bar s5 to the machine. By moving
the two contact shoes backwards and forwards the number of the elements in-
cluded in each current circuit can be altered in the same manner as already
described with regard to Figure 1.
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. The combination with a battery of accumulators having at least two groups
of cells of a controlling apparatus so connected thereto that the cells of one of the

page_text: groups can be cut in singly or by sections and after all have been included re-
placed by the second group of cells which is undivided, and then the cells of the
first mentioned group cut in again singly or by sections.
2. The modification of the invention wherein two controlling apparatuses are
combined with a battery of accumulators one of which varies the connections of
the cells with the charging circuit and the other varies the connections of the cells
with the current consuming circuit substantially as described with reference to
Figure 2 of the drawings.
3. The controlling apparatus for accumulators constructed and operating
substantially as described with reference to Figure 1 of the drawings.
