  • the setting of the discriminator results from an impulse series.
  • the discriminator device is set by means of two series of impulses.
  • the impulse relay for the vertical magnet H of the finder switch as well as for the rotary magnet D is provided by the relay RI.
  • the relay V is energized.
  • the impulses affecting the vertical magnet H are thus transmitted to the selector De over the following circuit (characterizing selector for the tens digit of the number of the calling subscriber): earth, contacts 24M, 26u, magnet Dz, battery, earth.
  • the wipers of the switch mechanism are operated to a particular contact by means of the magnet De, so that the wiper del connects a particular contact, in the tens contact series Z of the meter sending ZG, with earth potential.
  • the relay V restores.
  • the rotary steps of the finder switch are thus transmitted to the magnet De of the switch mechanism over the following circuit which characterizes the units digit of the number of the calling subscriber: earth, contacts 24H, 251i, wiper cia3 in operative position, magnet De, battery, earth.
  • the wipers of the switch mechanism are operated to a particular position by means of the magnet De, so that over wiper del a particular contact of the meter sender ZG in the unit contact bank E is connected with earth potential.
  • the following circuit is completed for the relay A in the first group selector: earth, winding II of relay A, lower talking conductor b, contact 2pl, wiper b of the finder switch, subscribers loop, upper talking conductor a, wiper a of the finder switch contact I pl, winding I of relay A, battery, earth.
  • the relay A operates and by removing the short-circuit at contact 33a connects the seizing relay C of the group selector.
  • Relay C closes its contact 46c and locks up independently of the off-normal contact 39lclc.
  • the subscriber now sets up the desired connection by sending out dial impulses.
  • the setting of the rst group selector is not important for the invention and is therefore not shown.
  • the test relay P2 is energized over its windings I and 1I and over the test wiper c of the group selector.
  • the dial impulse series which follow are transmitted to succeeding connecting devices over contacts 38a, 28e, 3
  • the locking conductor is further connected with earth potential over resistance and contact Mp2 so that the release of the line to the subscriber is in the rst place prevented.
  • the repeater ZZZ for the time zone metering now sends out the number of metering impulses which has been determined. This takes place by the repeated energizing of metering impulse relay Za.
  • the metering impulses are transmitted .to the metering relay Zr in the group selector over the following circuit: earth, battery, resistance Will, contacts 53m. 54M, lower talking conductor, wiper b of the group selector, contacts 32122, 33e, 35e, winding of the metering relay Zr, earth.

  • the relay Hi not shown, in the repeater ZZZ is energized and by opening the contact 54M disconnects the metering battery from the lower talking conductor and over Contact 55h
  • the registering device can be controlled by the dial impulses sent out and thus the registering elements are displaced which make possible the recording of the desired number. Further other registering elements can be controlled by the metering impulse rela-y, so that the number of metering periods to be reckoned can be indicated. Further the registering device indicates the number of the calling subscriber.
  • the wiper of the meter sender is operated to the rst contact so that the wiper daI stands on the rst contact of the tens sending contact group ZT.
  • the magnet Da operates its contact 45da and thereby connects the slow relay J as follows: earth, contact 45da, winding I of relay J (parallel to the resistance Wi), resistance WiB, battery, earth.
  • Relay J opens a point in the circuit indicated above the magnet Da at contact 607'. The magnet Da is thus deenergized and opens contact 45de, so that relay J is disconnect'ed. This further closes the contact 607' and completes the energizing circuit for the magnet Da again. The wipers of the meter sender are thus moved to the next contact.
  • the relay J which is energized and deenergized for each step of the wiper of the meter sender, by closing its contact 317' sends a denite number of impulses to the registering impulse over the following circuit: earth, contacts 317', 36pa, 34e, 32102, wiper b of the group selector, contact 55h
  • the digits of the call number of the last two positions are characterized by the connection of calling potential. It is assumed that the meter sender shown is associated with the 340th of a hundred group. In the ten thousands contact groups of the meter sender, the contact 3 is thus characterized by the connection of earth potential, in the thousands group contact 4, and in the hundreds group contact I0.
  • the calling subscriber has the number 34057.
  • the wiper dal reaches the contact 3 of the tens sending group ZT, i. e., three impulses are sent out to the registering device RE by means of contact 311', so that after the operation of the relay J the following circuit is closed for the relay Pa: earth, contact 3 of the tens sending group ZT, wiper dal, contact 567', winding II of relay Pa, battery, earth.
  • the relay Pa connects itself in the following holding circuit: earth, contacts 581m, 51e, winding II of relay Pa, battery, earth.
  • the contact 361m is opened and remains open in the rst place so that by the succeeding operations of contact 317' no impulses are sent out to the registering device RE.
  • the wiper dal is thus connected over the succeeding contacts without the contact steps being registered.
  • the wiper daI connects with the winding I of relay Pa so that after the operation of the relay J the following circuit is completed: earth, contacts 581m, 51e, 567', wiper daI, winding I of relay Pa, battery, earth.
  • winding I of relay Pa is wound in the opposite direction to winding II as isclear from the drawings, since the winding II connects positive to the upper soldering pin 2 and the negative to the lower pin I while the winding I connects the positive to the lower pin 4 and negative to the higher pin 5.
  • Relay Pa is therefore released and thus interrupts the holding circuit of contact 581m.
  • the contact 361m is again closed and the sending of impulses to the registering device begins again on the release of relay J and closing of contact 317'.
  • the circuit of the registering device is again interrupted at contact 361m, and remains interrupted during the resulting stepping on of the wipers of the meter sender since the relay Pa locks up over contact 58'pa.
  • the wiper dal reaches the contact immediately in front of the hundreds-contact group H the wiper dal is again in contact with the reverse winding I of the relay Pal so that this relay restores, and by closing Contact 36pa makes it possible to send out impulses from the registering device again.
  • the nder switch which is connected in order to come to rest on a decade on which the calling subscriber is connected has executed 5 vertical steps. These 5 vertical steps will be repeated as previously described to the magnet De' whose wiper dzI has connected earth potential to the contact 5 of the tens-contact group Z.
  • the wiper dal in the course of its movement and after the transmitting of the 5 impulses to the registering device RE, reaches the contact 5 of the tens-group Z the relay Pa is energized in the following circuit: earth, battery, winding II of relay Pa, Contact 567', wiper dal, contact 5 in the tens-contact group Z, Wiper dal, earth.
  • the Wiper del by means of the '7 rotary steps for the finder switch, is set on the contact 'I of the units-group E in order to reach the calling subscriber. Finally, '7 impulses are sent out to the registering device.
  • the wiper dal reaches the contact 'I in the units-group E a circuit is completed for the relay Pa once more: earth, battery, winding II of relay Pa, contact 567', Wiper dal, contact 1 in the units-contact group E, wiper del, earth. 'Ihe relay Pa, locks up again by closing its contact 581m.
  • the circuit for the registering device is interrupted so that by the further stepping on of the register sender the registering device is not iniiuenced.
  • the wipers of the register sender are stepped on to the home position where the following circuit is completed for the relay J over winding II: earth, wiper da2 in rest position, contacts 62g', 531ml, winding II of relay J, battery, earth.
  • Relay J remains energized in this circuit until the relay Pa is restored so that the magnet Da of the meter sender ZG can receive no further impulses. The release of the relay Pa results by action of the registering device.
  • the registering operation for example the printing operation, is carried out in known man ner.
  • the relay P2 By the setting up of the seizing circuit the relay P2 is also restored. By the opening of contact Mp2 earth potential is removed from the locking conductor so that the test relay PI of the finder switch is released. By the closing of contact Hpl the rotary magnet of the finder switch is connected: earth, contacts Ido,
  • magnet De earth, contacts Illa, Mp2, 46j, wiper dz2 in home position, wiper de2 in operating position, magnet De, battery, earth.
  • the magnet De has a contact 44de which connects the relay J and the latter interrupts the circuit for the magnet De at contact 46j.
  • Fig. 2 shows a further embodiment of the subject of the invention which is so arranged that in contrast to the arrangement according to Fig. l the operations for repeating the number of the calling subscriber in the registering device and the switching devices, are simplilied.
  • Fig. 2 only parts of the rst group selector are shown i. e., the part which in Fig. l is connected between the two dotted separate lines.
  • the finder switch AS situated in front of the group selector and the repeater ZZZ situated behind it correspond accurately to the corresponding organ of Fig. l with the exception that contact I llc in the finder switch is dispensed with in the arrangement according to Fig. 2.
  • the impulses for setting the finder switch in the two impulse trains i. e. for setting up the nder switch to a denite contact bank, and then rotating the switch on to the calling subscriber, are repeated to both switch mechanisms by means of magnets De and De.
  • special wires of these switch mechanisms for characterizing the tens and units positions of the calling subscriber in the contact bank of the meter sender ZG are not necessary.
  • the meter sender ZG can be simplied as it only serves to repeat the group characterization, i. e. the rst three digits of the call number.
  • the wiper idg serves to repeat the impulse series for the registering device RE in the repeater ZZZ by which the group characterization comprising the rst three digits of the number of the calling subscriber (ten thousands, thousands, hundreds) is indicated.
  • the wiper ldg reaches the contact which is connected up, an impulse is sent out for registering over the following path: earth, contact 14e, wiper idg of the meter sender ZG lower talking conductor, contact 32132, wiper b of the group selector and further to the registering device RE in the repeater ZZZ (in Fig. l).
  • the wiper idg is then connected over the hundreds contact group H and thus sends impulses to the registering device.
  • the three rst digits N340 have been indicated in the registering device, and with the aid of the relay interrupter RU the meter sender is stepped on until its Wiper idg has reached the contact by which the relay X is connected.
  • This relay then operates in the following circuit: earth, contact 14e, wiper idg, winding of relay X, battery, earth.
  • the relay X locks up in the following circuit: earth, contacts 16e, 153,', winding of relay X, battery, earth.
  • the relay X opens its contact 19a: and thus the impulse circuit for the magnets Dg, so that the meter sender ZG remains operated.
  • the relay interrupter RU is connected to the magnet De to which the vertical steps of the finder switch were repeated.
  • the magnet De receives impulses from the relay interrupter RU over the following path: earth, relay interrupter RU, contact 18m, wiper ide in operating position, magnet De, battery, earth.
  • the magnet De has a contact 12de which is closed each time the magnet is energized.
  • an impulse is transmitted to the registering device RE over the following path: earth, contacts 13x, 12:12, lower talking conductor, contact 32112, Wiper b of the group selector and further to the registering device RE (in Fig. l).
  • the registering device therefore takes up as many impulses by means of the contact 12de as are necessary to step on the switch mechanism with the magnet D2 from its set position to its home position.
  • the complementary number is transmitted to the switch mechanism Dz over the registering device.
  • the registering element which records the tens digit of the call number must therefore be provided with an inverted series of numbers.
  • the magnet De also has a contact 'iide which is closed for every energization of the magnet and transmits impulses to the registering device RE in the repeater ZZZ over the following path: earth, contacts 13:11,', Tide, lower talking conductor, contact 32102, wiper b of the group selector and further to the registering device (Fig. l). Also in this case the complementary numbers of the switch mechanism are transmitted to the registering device by means of the magnet De so that the meter series of the registering element must be inverted in order to record the units digit in the same manner as for recording the tens digit. When the wiper ide has reached its normal position the circuit for the magnet De is interrupted over this wiper.
  • the relay E in the group selector is restored by means of the repeater ZZZ.
  • the magnet Dg of the meter sender is then connected over the following path: earth, relay interrupter RU, contact 80e, Wiper Zdg in operating position, magnet Dg, battery, earth.
