—the combination with each group of lines and their con-
nectors, and with the main distributor, main selector, and
manipulator for common use by a group, of a rotary return-
to-rest distributor or multiple switch formed of a plurality
of sets of pairs of contacts and of brushes electro-magneti-
cally revolved together as one, whereby to concurrently effect
various circuit changes; and of electro-magnetically
operated mechanisms to which local currents are sent
through said return-to-rest distributor, said mechanisms
being respectively adapted to return to initial position the
line-connector which has been operated, and the main dis-
tributer, main selector, and manipulator of the group to
which that line belongs. (10.) In an automatic telephone-
exchange system in which the subscribers’ lines are divided
into groups, and presented by line- and service-contacts to
coupling-devices composed of pairs of electrically operated
couplers, having sets of contact-fingers selectively controlled
and electrically associated at predetermined moments as
described, the several pairs of associated couplers being
located with regard to the groups of lines in the manner
described ; and in which there is connected with each sub-
scriber’s line an electro-magnetic multiple commutator,
designated a connector, adapted to act as described, and in
which there is combined with each group of lines a set of
electro-magnetic apparatus (for use in common by all the
lines of the group), comprising an electro-magnetically
actuated rotary main distributor or multiple switch, con-
structed and adapted to act as described ; a main selector,
comprising electro-magnetically operated mechanisms, to
each of which in turn the signals sent are switched by the
main distributor, the action of the said mechanisms being
so co-ordinated that their conjoint action will have for effect
to complete one out of a number of selector-circuits ; and
a manipulator formed of relays and batteries adapted to
transmit through the selector-circuit completed, local cur-
rents corresponding to the signals which the manipulator
receives through the main distributor,—the combination,
with each circuit controlled by the main selector, of a double
polarised receiver, two rotary distributors or multiple
switches, and two different called-line couplers (designated
twin-couplers) located at different coupling-boards, and each
provided with electro-magnetically operated mechanism con-
trolling its motion across the coupling-board, and with a con-
tact-fingers’ selecting mechanism determining the bringing
into operation of one or other of its sets of contact-fingers,
the circuit-connections of the double polarised receiver with
the distributors, and of the distributors with the mechanisms
of the respective couplers, being such that the one or other
distributor and the one or other coupler will be actuated
according to the polarity of the first current by which the
polarised receiver is influenced, whilst the other distri-
buter and the other coupler are blocked in position of rest.
(11.) In an automatic telephone-exchange system in which
the subscribers’ lines are divided into groups, and presented
by line- and service-contacts to coupling-devices composed of
pairs of electrically operated couplers having sets of contact-
fingers, selectively controlled and electrically associated at
predetermined moments as described, the several pairs of

multiple commutator, designated a connector, adapted to act
as described ; and in which there is combined with each
group of lines a set of electro-magnetic apparatus (for use in
common by all the lines of the group), comprising an electro-
magnetically actuated rotary main distributor or multiple
switch, constructed and adapted to act as described, a main
selector comprising electro-magnetically operated mechan-
isms, whose action is so co-ordinated as to complete one
out of a number of selector-circuits, and a manipulator,
adapted to transmit through the selector-circuit completed,
local currents corresponding to the signals which it receives ;
and in which there is combined with each such circuit a
double polarised receiver, two rotary distributors or multiple
switches, and two different called-line couplers (designated
twin-couplers), located at different coupling-boards, and each
provided with electro-magnetically operated actuating me-
chanism and with a contact-fingers’ selecting mechanism,
the circuit-connections of the double polarised receiver
with the distributors and mechanisms of the twin
couplers being such that the one or other will be actuated
according to the polarity of the first current by which the
polarised receiver is influenced,—the combination with each
of the twin called-line couplers controlled through the same
selector-circuit of a calling-line coupler ; each of such two
calling-line couplers (designated quasi-twins) being provided
with electrically-operated mechanism adapted to set the
coupler in motion by a current transmitted to said mechanism
through the distributor appertaining to the associated called-
line coupler, and through the line-finger circuit of the as-
sociated couplers ; each calling-line coupler being also pro-
vided with electrically operated mechanisms adapted to
arrest the motion of the coupler by the action of a current
transmitted to such mechanism through the service-finger
circuit of the calling-line coupler on the completion of said
circuit by a service-finger of the calling-line coupler meeting
a service-wire which has been put to earth by the previous
operation of the connector appertaining to the line to which
such service-wire belongs. (12.) In an automatic telephone-
exchange system in which the subscribers’ lines are divided
into groups, and presented by line- and service-contacts to
coupling-devices composed of pairs of electrically operated
couplers having sets of contact-fingers selectively controlled
and electrically associated at predetermined moments as
described, the several pairs of associated couplers being
located with regard to the groups of lines in the manner
described ; and in which there is connected with each sub-
scriber’s line an electro-magnetic multiple commutator desig-
nated a connector, adapted to act as described, and in which
there is combined with each group of lines a set of electro-
magnetic apparatus (for use in common by all the lines of the
group) comprising an electro-magnetically actuated rotary
main distributor or multiple switch, constructed and adapted
to act as described, a main selector comprising electro-mag-
netically operated mechanisms to each of which in turn the
signals sent are switched by the main distributor, the action
of the said mechanisms being so co-ordinated that their con-
joint action will have for effect to complete one out of a
number of selector-circuits, and a manipulator formed of
relays and batteries adapted to transmit through the selector-
circuit completed, local currents corresponding to the signals
which the manipulator receives through the main dis-
tributer ; and in which there is combined with each such
circuit a double polarised receiver, two rotary distributors,
and two called-line couplers (designated twin-couplers)
located at different coupling-boards, the circuit-connections
of the double polarised receiver with the distributors and
mechanisms of the twin-couplers being such that the one or
other will be actuated according to the polarity of the first
current by which the polarised receiver is influenced ; and in

couplers controlled through the same selector-circuit a
calling-line coupler, each of such two calling-line couplers
(designated quasi-twins) being adapted to be set in mo-
tion by a current transmitted to its mechanism through
the distributor appertaining to the associated called-line
coupler, and through the line-finger circuit of the associated
couplers ; such calling-line coupler being also adapted to be
arrested by the action of a current transmitted to its mechanism
through the service-finger circuit of the calling-line coupler,—
the combination with the line-connectors, and with the main
distributor, main selector, and manipulator common to the
group, and with the mechanisms of the called-line couplers
(designated twins) that are controlled through the same
selector-circuit, of two return-to-rest rotary distributors, each
formed of a plurality of brushes electro-magnetically revolved
over a plurality of sets of pairs of contacts, of which the cir-
cuit-connections (with the mechanisms of the called-line
couplers, with the connectors of the lines of the group, and
with the main distributor, the main selector, and the mani-
pulator common to the group) are such that the action of
the one or other return-to-rest distributor will be dependent
on the previous operation of the distributor of the twin
called-line coupler with which such return-to-rest distributor
is associated, and will have for effect to transmit local cur-
rents to the several mechanisms with which it is combined,
whereby to return to initial position the line-connector, main
distributor, main selector, and manipulator appertaining to
the group.
