Description

Different tariffs are often used in telephone systems. So are z. B. brought lower fees into account for connections at night time than for connections during the daytime and especially during rush hour. The present invention relates now to systems in which different values Connections are made and in those equipped with self-loading devices Connection positions are available. It aims, also in these systems, the different fee tariffs from the Operation to meet the requirements that arise in the simplest and most expedient manner. To achieve this, the respective tariff (e.g. day and night tariff) characteristic switching devices in the exchange on the various

zo the value of self-incriminating the connection points in such a way that they are controlled in a manner corresponding to the respective tariff by self-incriminating switching measures of the speech stations.

Switching devices that determine the tariff changes can at the same time tariff displays on the call stations and switching devices in the exchanges, which registration devices to determine all Influence, control, overall loads at a connection point.

In the drawings, an embodiment of the inventive concept is shown.

In Fig. 1, the parts of a coin operated telephone MF are shown at the top right, insofar as they are important for explaining the subject matter of the invention. The office part AT which is individually assigned to the remote coin-operated speaker is connected to the two speech cores α, b going out from the coin-operated telephone. The connections are made via a preselector VW shown on the right in the drawing and other numbered surge receivers (not shown). Furthermore, a switching device GZE with six switching arms is shown on the left in FIG. is designated. An apparatus ZPR , referred to in the description as a zone tester, is connected via three wires O ₁ , m, r going out from this switching device (see FIG. 2, which is to be added to FIG. 1 on the left), to which in turn (see left-hand side Part of Fig. 2) a device referred to as counting set ZS in the description is connected.

From the payphone station itself, the collection magnet EM, the return magnet RM, a contact 2 g ₁₀ actuated by thrown in io-penny pieces, a contact 1 g _Sd actuated by thrown 50-pfennig pieces , a flag galvanoscope SG and the im. Quiet-

state of the hook switch HU connected to earth. The two wires a, b outgoing from the coin phone are connected to two money pulse relays G ₅₀ and Gi ₀ in their circuit extension in the office - In the rest position of the coin phone there is a _o closed circuit, which is o of the Xo indicator galvanoscope allows current to flow in the two wires α and b only in one direction. At one end of the fork there is an earthed office battery via relay An, contacts 3 a », 4 free and 5 from , while the other end of the fork is connected to earth via the closed hook switch ab, qbes, closed contact 3 an, winding of the relay An, branch point y, _ winding I and via contact 6 «winding II of relay G ₅₀ , contacts 15 e, 12 1 parallel to this from branch point y via winding I of relay G ₁₀ , Contacts 8 r, ιοί, then further in parallel over both wires a and &, contacts _{2g "10} , χ g- ₅₀₎ cashier magnet BM, return magnet RM, indicator galvanoscope SG, branch point x, hook switch HU, earth. The contacts 6η and Jn are below the influence of a relay N, the at. Providence multiple tariffs, for example a day and night tariff it denotes the tariff in force, which is caused by switching operations, as described in the following. the relay N is controlled by a clock such that e For example, as shown in the drawing, it is excited between 7 p.m. and 8 a.m. Either of the two. Money pulse relays G ₅₀ and G _{10 have} two windings. I and II. Both the windings I of both Re- ^ -lis and their Wicklungsll have the same resistance. One of the 'windings II of these two relays' is now' switched alternately in the morning at 8 a.m. and in the evening ig o'clock in parallel to winding I of the same name, so that during the daytime as a result of the parallel connection of the two windings of relay G ₅₀ at contact 6 η the c -Ader is traversed by a current of greater strength than the & -Ader. During the night, when the ^ relay N is excited and the contact 7 η is closed, the current branching in the two wires changes in the opposite sense. The consequence of the different strengths of current flow in the two veins is that the indicator galvanoscope is influenced in such a way that it deflects a pointer it moves by a certain amount. The distraction is thus opposite during the nighttime to that during the daytime. In this way, the tariff in force at the time of the call, night or day tariff, is displayed to a speaking guest.

In the current flow described above, which exists in the idle state, the return magnet and the cashier magnet do not receive enough current to be actuated, even if the current load of the two veins changes, as just explained. These two magnets are activated by amplifying the current either on wire α or b. The current gain occurs when the low-resistance relay P is switched on instead of the relay G ₁₀ or G ₅₀ on one of the two wires. This can be done, as will be explained later, by closing the contact 9 r , which causes the current to flow through the β-wire and thus the excitation of the return magnet RM , or by closing the contact t / \. E, which causes the current to flow in the & -wire amplified and the excitation of the cashier magnet EM is caused. Only the relays An :, G ₁₀ and G ₅₀ respond in the circuit mentioned, that is to say in the idle state of the coin-operated telephone MF, and keep their contacts in the working position.

In the case of the pay phone shown here, it is possible to establish both local and long-distance connections. Since the device is also intended for the production of relatively high-quality connections (connections can be made according to the example for which the speaking guest has to pay according to the daily tariff i, 209Ui ), the arrangement is made so that the amount to be paid both in io-pfennig-pieces, in 50-pfennig-pieces or at the same time with both types of coins.

The coins, which can also be inserted in any order, are before they are picked up by the payphone, by a control device examined for authenticity and suitability, a measure that explains the present Invention proposal is irrelevant and therefore not further described! will. . _,

Depending on the type, the coins are guided on different paths in such a way that after inserting a 50-pfennig piece the contact ι If ₅₀ , when inserting an io-pfennig piece, the contact 2 g _{ia is} opened. ng

It should also be noted that the two contacts Ig ₅₀ and 2g _{t0 are} not under the influence of the relays G ₁₀ and G ₅₀ , but are purely mechanical contacts, only actuated when coin is inserted, the latter having to take place when the hook switch contact is closed. So the coin slot takes place

instead of before the handset is lifted off the hook.

Let us now first describe a local connection for which a fee of 10 pfennigs is to be paid both during the day and at night. The participant throws the io-pfennig piece into the money slot without lifting the hook switch. As already mentioned, the coin is checked by a coin validator. After this process, it passes through the receiving channel and briefly opens contact 2 ^ ₁₀ . As a result, the flow of current in one fork branch, namely in the α-branch, is interrupted and the relay G ₁₀ for a short time. Brought garbage. Therefore, in the money and time setter GCW the contact 16 ^ ₁₀ is closed so that the rotary magnet D ₁₀ is a current surge in the following way: battery, earth * rotary magnet D _10, contacts 16 g of _10, ¹ 7 IF50 (d ^as relay G ₅₀ remains excited, as has been no interruption of & Vein by inserting the 10-penny piece), contacts 20 p, 22 on (the relay is on, as the hook switch HU has not yet been actuated, nor excited), earth . The rotary magnet D ₁₀ therefore advances its switching arms 1 to 6 shown on the left in FIG. Since it is a local connection, no further payment of coins is made, the magnet D _{10 is} not further influenced, so that its switching arms stop on the contact 1.

If the subscriber now lifts the receiver and thereby switches the earth off from the hook switch HU , the current flow through the fork is interrupted and ti.-a. the relay on brought to waste. As a result, the contact 21 to be closed and thereby ι at the contact of the swept by the switching arm 2 Contact Bank earth applied: earth contacts 21 on, 23 /, 25 ", 2SD _2, 3OD _1, switching arm 2 of the money and time setter GZE, contact 1. The contacts of the contact banks swept by the switching arms 1 to 6 are connected to money rails r to 6 and wired according to the fee distribution and the zone.

For example, money rail 1 applies to local connections for which 10 pfennigs are to be paid, rail 2 for connections to the first remote zone, for which a daily fee of 30 pfennigs and a night fee of 20 pfennigs is charged, etc. Also for money and time adjusters a setting is made to the corresponding tariff, day or night tariff. In the case of a connection according to the daily tariff (as assumed for this example), contact 25 »is closed, while contact 26 η is closed during the time during which the night tariff applies. These contacts are also under the influence of the relay N controlled by a clock.

By the drop of at the contact 31 to be closed and thereby the current circuit for the rotary magnet Dvw the preselector VW is closed further comprising: earth contacts 31 on, 33 ^ 3 5 bes, 36 o, rotary magnetic Dvw, battery, earth. The rotary magnet Dvw works with the relay O as a breaker in such a way that when the magnet Dvw is first excited, contact 37 dv is closed and a circuit for relay O is established: earth, contact 37dv, winding of relay O, battery, earth . The just beschriebene'Stromkreis is ο on Kontakt36 opened for the magnet Dvw, so that the circuit for the contact 37 O dv turn geöffnet.wird. The rotary magnet Dvw is ο on the back closing contact 36th energized again, etc. This game continues until the switching arms a, b, c of the preselector VW are on a next free connection device, for example a free I. group selector /.

At the moment when this occurs, the relay " T " in the preselector VW is excited in the following way: Earth from the next free connection device, wire c, switching arm c of the preselector VW ₁ contacts 38 bes, 39 on, windings II and I of the relay · T ₁ battery, earth. Relay T closes its contact 41 1, thereby shorting its high-resistance winding and thereby blocking the connection device found against other occupancy. Relay Z, which is parallel to winding I of relay T , cannot yet respond in this circuit. By responding to T , the contacts γοϊ and 12 1 are still opened and the exchange part AT assigned to the payphone is disconnected from it. By closing the contacts iri and 13 1 , the payphone is connected to the free connection device found 1 the circuit for the rotary solenoid of the preselector is opened and the selector is shut down by closing the contact es 32 ί the following circuit is closed for the second winding of relay M : earth, contacts 310 ·% 32 1, 427% winding II of relay M ₁ battery, earth. The relay M responds and closes its contacts 45 · m, 46 ″, 48 m. By actuating these contacts, the wires%, m and r, via which a zone tester ZPR can be reached, are switched on.

This; Game between the torque magnet Dvs and the relay G continues until the "switching arms ι to 8 of the connection seeker VS have adjusted to the .den Adernai, tn andr connected time and money adjuster GZE . Do the switching arms have the relevant contact is reached, the following circuit is effective via the switching arm 8 : Earth ^ windings II and I of the relay P ₁ , contacts 53 m _lf 59A> switching arm 8 of the connection finder VS., wire r, contacts 48 m (Fig. 1), 62hes, 6jp, .WicklungI of the relay M, winding I. of the relay R, battery, earth. In this circuit, the relays M and R in the money adjuster GZM and the relay P ₁ in the zone tester ZPR are energized. At contact 427- (Fig. 1) the second winding of the relay M is turned off. However, the contacts of this relay remain actuated because the relay is held still energized via its first winding. By closing the contact 43 r is turned on, the second winding of the relay R and the following so for this relay Holding circuit closed: earth, contacts 31 on, 32 i, 43 r, winding II of relay R, winding I of relay R, battery, earth. In the Zönenprüf he ZPR was in the mentioned, about the. Switching arm 8 of the connection finder VS running circuit the relay P ₁ come. At contact 64 ^ ₁ , this relay closes its high-resistance winding I and thereby blocks the money and time setter GZE from being used by other connection seekers. The circuit for the rotary magnet Dvs is opened at contact 58 ^ ₁ and the connection finder is thereby stopped. Closing contact 65 P ₁ creates the following circuit for relay S ₁ : earth, contact 65 ^ ₁ , winding of relay A ₁ , battery, earth. At contact 66 ^ ₁ is for. the delay relay V ₁ closed the following circuit: earth, battery, winding of the ReIaIsF ₁ , contact 66 ^ ₁ , holding arm IV of the tracking plant MWl in rest position, contacts 51O ₁ , 52 h, earth. Furthermore, the relay P ₁ also opens the contact 6Jp ₁ and closes the contact 6Sp ₁ . This prepares the excitation of relay A , which shortly afterwards, when contact 69% is closed, is excited in the following circuit: earth, battery, winding of relay A, contacts 69 ^ ₁ , 6Sp ₁ , switching arm 7 of connection finder VS , Wire a _x , contact »(Fig, χ), wire b, contact ι If ₅₀ , winding of the cashier's magnet EM, indicator galyanoscope SG, winding of the return magnet RM,, contact 2 ^ ₁₀ , wire a, resistance Wi, contact jom, earth .

Circuit 'for' the winding I of the relay G. The relay V ₁ opens when it is energized the 'contact 71 V ₁ and closes the contact 72 ^ ₁ , whereby the following circuit is closed for the relay V ₂ : earth, battery, winding of the Relay V ₂ , contacts 72 V ₁ , 74 a, 75 f, 7Sr ₁ , earth. The relay V ₂ opens its contact 8σζ / ₂ and closes its contact 79 V ₂ and thereby switches the rotary magnet DmW _{1 of} the traveling mechanism MW I under the influence of the impulse contact of A.

The first series of impulses sent by the calling party indicates whether the desired connection is a local or a long-distance connection. It is assumed for the present example that a digit between the numbers 2 to 8 must be selected as the first digit when making local calls. The contact bank "swept by the switching arm r of the co-running mechanism MWl" is therefore also designed so that the contacts 2 to 8 are wired to one another and the relays O , which characterize the local connections, are routed Relay A in the zone tester ZPR is influenced by the interruptions caused by the impulse transmitter on the coin-operated telephone. Every time A drops out, a circuit is closed for the magnet DmW _{1 of} the moving mechanism MW I: earth, battery, winding of the rotary magnet DmW ₁ , contacts 79 V ₂ , 73 a, 75 f _{s 7Sr 1} , earth. This circuit is closed and reopened five times during the transmission of the five number current surges by the calling subscriber. The rotary magnet DmW ₁ therefore switches its visual arms I to IV forward five steps. The follow-up mechanism MW I is designed so that the switching arms II and III at an angle v on 120 ⁰ are offset in relation to the switching arms I and IV.

A switching process is therefore not carried out via the switching arms II and III when the co-running mechanism MW I is set by five number current surges. After the end of the series of impulses, the relay V ₁ , which, as soon as the traveling mechanism MW I with its visual arms has left the rest position after the first impulse that takes effect on the magnet DmW _x , is via the contacts 81 a, 82 W ₂ and 65 ^ ₁ holds and, since it is designed as a delay relay, during the short power interruptions at contact 81 α keeps its contacts in the working position, brought to waste.

By opening the contact 72 V ₁ , the circuit for the relay V _{2 is} interrupted, which however, thanks to its design as a delay relay, lasts for a short time. During this fall time, the following circuit is closed for the winding I of the relay O : Earth, battery, contacts 83 «Ι, · 85 ^ ₂ , 86 /, switching arm I of the follow-up mechanism MW I, contact 5 of the contact bank I which it has marked, Winding I of relay 0, earth. The relay O closes the following holding circuit: earth, contacts 8Sr ₁ , 870, 'winding II of the ReIaIsO ₁ , battery, earth. By closing contact 89 0 , the following circuit is closed for the first winding of relay G : earth, battery, winding I of relay G, contact 89 o, busbar 11, which is connected to contact 890, switching arm 1 of connection finder VS, zone rail i, contact 1 to which the money and time adjuster GZE was set, switching arm 2 of the money and time adjuster GZE, contacts 3.Od ₁ , 28 ^ ₂ , ² 5 ^ 23 /, 21 on, earth. By closing contact 91 0 , the following circuit is closed for relay H : earth, battery, winding of relay H, contacts 90 u, 910, 7 & r _lt earth. As a result, relay G is placed in the following holding circuit: earth, contacts 93-Äj, 92 g, winding I of relay G, battery, earth.

The relay G checks in this way whether the inserted amount corresponds to the charge for the connection that the subscriber wishes to establish. The addressing of G is thus the indicator of a correct counting for the desired connection. The contact 94g is opened, and thereby the occurrence of a h extending through the contact 60 energizing circuit for the coil of the relay II Bes in money and time setter GZE, a process ^Io o is explained in more detail later prevented.

As soon as the relay G has verified the accuracy of failure to pay, the role of the auditor zone ZPR is satisfied, ¹⁰ S that was shut down and provision for other connections nothing stands in the way. The triggering of the zone tester takes place in the following way: The above-mentioned excitation of the relay H opens the contact 59 h and closes the contact 60 h. As a result, the previously mentioned circuit running over the switching arm 8 of the connection finder VS , in which the relays P ₁ in the zone tester ZPR and M ¹¹ S and R. were excited in the money setter GZE , opened. The relay R in the money maker remains energized via its contact 43 r. Relay P ₁ drops out in the zone tester ZPR . The circuit for the "relay R _{1" is} interrupted at contact 65 j>. This drops out and opens at contact 88 Y ₁

The magnet severed at its contact · g4, ämw _i the above circuit for the relay A on ,, the un'd opens thus its contact 740 opens, the circuit for the rotary magnet. At the contact g4dmw _t the current circuit for the relay A is closed again, so that the rotary magnet DmW ₁ receives a new pulse. This game between the rotary magnet Dm ¹ W ₁ and relay A is repeated so often: until the SehaltarmilV of Mitlaufwerkea MW I has expired from its return segment ttttd has reached the normally closed contact. In this position: Relay A can no longer respond. The zone tester ZPR has thus been returned to its rest position.

The relay M in the money and time adjuster GZß had dropped out. By. When the contacts 48 m, 46 m and 45 m are opened, the ZPR zone tester. Leitongen (C ₁ , πι and r switched off.

Let it now be assumed that the calling subscriber has established the connection to the desired subscriber by sending out further series of numbers and thereby setting not shown, the preselector VW next- • 45 ordered connection devices. If the desired subscriber answers, so will Via the c-wire an incentive, the counting stimulus, is transmitted in such a way that the relay Z lying parallel to the winding I of the relay T responds by amplifying the current on the c-wire. The relay Z closes its contact 100 z, whereby for the second. Winding of relay E, the following circuit is closed: earth; contacts ggr, laas, XQi f, second winding of relay .5, local call counter: ZO, battery, earth.

The counter ZO is designed in such a way that it only responds when the winding II of the relay E is excited in series with it, but not even if, in this case, yes; does not happen, the winding I of this relay, 'is switched on. The counter ZO is thus incremented each time a local connection is made, so that it records the total number of all local connections made by the payphone MF. The relay E is independent of the relay Z in a heating circuit running via the contacts 99 r and / 102 e. A hold circuit is also closed for relay Z; Earth, contacts 103m, 104.2, io§e / io6t, RelaisZ, battery, earth. The relay E opens its contacts io8ß and ι S e and closes its contact 14 #. The response of the relay E is the indicator that; the calling subscriber has received the connection to the desired subscriber and the deposited amount can be collected, which happens when the call is ended and the calling subscriber hangs up the receiver

If the conversation is ended and the hook switch HU earth is switched on when the handset is hung up on the part of the * end of the call, the connection is triggered by switching processes not shown here and of no further interest, and the relay activated via the c-wire falls back brought by opening the contacts χι # and 13 1 , the preselector VW "from the" lines α and b leading to the coin-operated telephone MF is switched off.

By closing contact 12 1 , the following circuit is created: earth, battery, contact ξ ab, winding of relay P, contacts 142, vz-t-, wire b, contact 1 g _s0 , winding of the collection magnet EM ₁ . Show galvanoscope SG, branch point x, hook switch HU, earth. Since, as already mentioned, the relay P has a low resistance, the current flow via the δ-wire to the coin-operated telephone MF is so strong that the cash-in magnet EM pulls through. is thus collected and the coins fall into the cash box. The collection process is triggered by relay J? secured, which, although its hold circuit at contact 32 * was opened, thanks to its design as a delay relay, the circuit for the relay £ at contact ggr maintains long enough to safely complete the checkout process.

In the circuit mentioned above, the ^ relay P was also energized. It closes contact 109 ^. At the moment when the relay R drops out, the relay A η and the first winding of the "relay G _{10" are} applied via contacts 5 ah, log-pr, battery and

The relay ^ 'and G ₁₀ speak in this circuit, and connect their contacts. If the holding circuit of relay £ at contact 99) is interrupted, windings I and II of relay O _{50 are placed} parallel to winding I of relay G ₁₀ at contact 15 £ with simultaneous disconnection of the winding of relay P and so, there after is falling of the relay P and open the contact 109 p meanwhile the contact 3 to be closed, the original state in which a quiescent current via contacts ζ · al ,. 4bes _r San flowing relay On, G ₁₀ , G ₅₀ , etc., restored.

If the connection just described is made during the time during which the relay N has been energized, ie at the time of the night tariff from 7:00 p.m. to 5:00 p.m., the contact 25 »is open and the contact 26 η is closed. The relay G imZanenprüf er ZPR , which checks the correct payment, is now energized via the zone rail 1, contact i, switching arm 5 of the money adjuster GZE, contacts 17Jd ₁ , 176 d * ,, 26% 23 f, 21 on, earth. In this case, no switching process takes place via the switching arm 2. Otherwise, the processes correspond to those already described.

Let us now describe the establishment of higher-quality connections, such long-distance connections, for which there is a charge depending on the zone in which the call is being made from 30, 40, 70, 90 and 120 pfennigs on Days and 20, 30, 50, 60 and Sun pennies during the night time are taken into account will. Assume that the subscriber has a connection in the third remote area want to establish, i.e. a connection for which a fee of 70 pfennigs per day, is credited at night from So Pfennigs. As mentioned at the beginning of the description the arrangement is such that the fee is paid both in units of 10 pfennigs can be paid as well as in units of 50 pfennigs and 10 pfennigs at the same time. It is initially assumed that the subscriber is seven individual io-pfennig pieces in the money

55. Throw in the coin operated telephone MF promoted. When the individual 10-pfennig pieces are thrown in, the contact 2g _{10 is} briefly opened, as already described, thereby causing the relay Gi ₀ to drop each time.

The magnet D ₁₀ receives current impulses: earth, contacts 22 on, 20 p, ifg _so , i6g _1Q (this contact generates the impulses for the magnet D _i0 }, magnet .D ₁₀ , battery, earth corresponding to the number of inserted coins The magnet P ₁₀ thus receives, in the present case, seven current surges and sets its switching arms 1 to 6 to the seventh contact If the subscriber picks up the receiver after inserting the coins and thereby, as described for local calls, also the relay An brings to waste, is via contacts 21 α «·, ² Sfί 2 $ n _r 2% άζ, _ 3 & ά _± , switching arm'2 of the GeIdeinsteileirs GZE ,. Contact 7 of the contact bank stroked by him, earth to the for the third far zone characteristic zone track4 created.

In the manner already described, the connection searcher VS belonging to the zone prescriber ZPR is started, which searches (via switching arm 8) for the money counter GZE that has come into effect.

For the present example it is assumed that every long-distance connection with Aus. Transmission of the code number ο must be initiated. In addition to the pre-selector VW, the connected connection devices set the tracking mechanism MW I in the zone tester ZPR in the manner described. After the first series of impulses, the switching arm I of this follow-up mechanism is thus on contact 10. Since no switching mechanisms are connected to this contact at the moment, there is no switching process via arm I and this contact. ^{The switching arms II and HI, which are offset by 120 Q} compared to the switching arm I, are on the contacts o after the first series of pulses. Since, in contrast to the previous example, the relay O was not now energized, triggering of the zone tester ZPR is also prevented for the time being. The second series of impulses, the. may consist of seven current surges, is accordingly also transferred to the magnet DmW _{1 of} the follow-up mechanism MWl . It should be "remembered that the circuit for the magnet DMW ₁ 'proceeds as follows:. Earth, battery, magnetic DMW _1, Kontakte79 ^ _2, 73 a, f 75, 78T _1, Earth The switching arms II and ΪΙΓ of Mitlaufwerkes MW I are thus brought to the seventh contact.

Earth, the relay G responds in this Electric circuits, which, as before, indicate the correctness of the deposit. . The initiation of the triggering of the zone tester ZFR takes place in turn by relay if. The relay. U ₁ , which is designed as a delay relay, drops a short time after opening the contact 121% and thereby closes its contact 90 m. The following circuit is now created for the relay H : Earth, battery, winding of the relay H ₁ contact 90 μ, at first rotary step of the MWTL tracking mechanism closed contact 128 w., earth. For the relay G, a holding circuit is again established via the winding I: Earth, battery, winding I of the relay G ₁ contacts 92 g, 93 h; Earth. The relay G opens its contact 94g and thereby prevents that after the relay H has responded and its contact 60 K closes the switching process via the switch arm of the connection finder VS _1, namely the excitation of the relay Bes on the money setter. If this relay Bes is not activated while a connection is being established, the connection can be established unhindered. Relay H conducts in exactly the same way as; triggers the zone tester ZBR beforehand and initiates the return of the Mitlaüfwerke MW I and MWH. It should also be noted that when relay F responds, contact ruf is opened and contact 112 / is closed. As a result, when the contact 67 ^ 1 is closed, earth is applied to the switch arm 7 of the connection finder VS , which is effective in the following circuit: earth, contacts 112 f, 6Jp ₁ , switch arm / of the connection finder VS, AAe-Ta ₁ , contact 44 w (Fig. 1) of the relay M in the money adjuster GZE ₁ winding I of the 'relay F ₁ battery, earth', which has since dropped out. In this circuit, the relay F in the money adjuster responds and closes a hold circuit on contact 129 /: earth, contacts 31 an, .. 32t, 129 /, windings II: and I of relay F ₁ battery, earth. Relay F opens its contact 101 f, thereby switching off the second winding of relay E and closing its contact \ 02 f, thereby " preparing a circuit for the thermal relay Thf.

If now, after establishing the connection and reporting the desired subscriber via the switch arm c of the preselector VW. Again the counting stimulus is given and the relay Z is excited as a result, is for the thermal relay Thf. following circuit closed: earth, contacts 99 ^ -1002, 102 /, ^12σ e, winding of the thermal relay Thf, battery, earth, the thermal relay Thf is so off-

formed that it only actuates its contact 132 thf after about 15 seconds. It is thereby achieved that the excitation of the relay E and the decision about the collection S of the inserted amount of money is delayed by about 15 seconds. During this time after the called subscriber has reported, the subscribers can speak without the inserted coins being collected if the caller gives the final signal by hanging up the receiver during this time. If, for example, the calling subscriber finds within this time, the so-called waiting period, that the subscriber reporting is not the one he wants, he quickly hangs up his receiver and thereby closes the contact on the hook switch HU. In a known manner, this causes the relay T of the preselector VW to drop, so that a current flow over the wire leading to the payphone arises which, since the low-resistance relay P is now switched on via contact or, is so strong that the Return magnet RM pulls through its armature and thereby transports the amount of money thrown into the return tray. This current flow runs as follows: earth, battery, contact 5 off, winding of relay P ₁ contacts 108 e, or, ιοί, wire α, contact 2g _{lt> 1} return magnet RM, indicator galvanoscope SG, branch point x, hook switch HU, earth.

If the calling subscriber is now correctly connected, contact 132 thf is closed after the waiting period has expired, i.e. after about 15 seconds, and the following circuit is created for relay B : earth, contact 132 thf, windings I and II des Relay B, local call counter ZO (which, since both windings of relay E are connected in series with it, is not energized in this circuit.), Battery, earth. The relay E closes the contact 102 e for itself a holding circuit and prepares by closing the contact 14 g coming after the closing bell pick the calling party to the effect circuit for the Einkassiermagneten EM before.

The thermal relay Thf is switched off at contact 131 e , while a circuit leading to the counting set (FIG. 2) is closed by closing contact 1302.

The counting set denoted by ZS in the drawing is a control device which is jointly assigned to a plurality of coin operated telephones and by means of which two counters ZF and KZ are incremented. KZ is a control counter that records the value of remote calls made by all of the payphones to which the counting rate is commonly assigned. The counter ZF is the remote counter which is individually assigned to each payphone and which is incremented for each long-distance call by the number of io-pfennig units that are to be paid each time for a call.

Since a local connection counter ZO (see Fig. 1) is now also arranged for each payphone, it is possible to determine the amount contained in the money box of a payphone with the help of these devices and thus avoid loopholes when replacing or emptying the money boxes to investigate.

The circuit indicated above runs: earth, contacts 99 r, xöog, 102 / v 1300, line ZK _x leading to counting set ZS (Fig. 2) , resistor Wi in counting set ZS, contacts 133 ds, 134 *, 135 s, winding of the Relay U, parallel to it resistance Wi, which is greater than the resistance of relay U, battery, earth. Relay U responds in this circuit. At contact 136 " the following circuit is closed for the magnet DS of the counting seeker: earth, contact τφιι, winding of the rotary magnet DS, battery, earth. The switching arms 1 to 8 of the count finder are thus brought to the first contact. At the same time, the circuit for the relay U is interrupted at the contact 133 ds go, so that the contact 1361; and thus the circuit described above for the magnet DS is opened. As a result, the contact 133 ds is closed again, the relay U is again energized and the circuit for the magnet DS is restored. This interplay between the rotary magnet DS and the relay U continues until the switching arms of the counting seeker have reached the contact indicated by the earth on the connecting line ZK _1. ^{Relay 6 1 is} excited via ZK ₁ , switching arm 7 of the count seeker, which finally interrupts the circuit for relay U at contact 13.5 J and thus stops the count seeker. By closing the contact 137 j the relay ISf determining the fee is switched on, which is energized by this switching process between 7 and 8 o'clock when the clock-controlled pointer is on the segment. A connection is established during the night established, the contact 139 "is opened and the contact 140% closed. This results in the switching off of the switching arm 2 of the tap ABW , which takes effect during the daytime, and the switching on of the switching arm 3. In the present case, however, the connection was according to the daily tariff established, thus the contact 139κ closed. By closing the contact

Has the tap reached its last contact; so 'is applied via switching arm 4 of the tap and contact 147 1 earth to ■ the peeling arm 8 of the counting set and thus to the wire ZK ₂ . The meaning of this switching measure is described in detail below. Before it should be mentioned that when the switching arm 1 of the tap runs off its contact segment and reaches the rest position, the holding circuit for the relay Γ is opened, so that the contacts 143 i, 145 1 and 147 * -opened. The earth potential applied via the wire ZKi is then switched off in any manner, so that the relay 5 also drops out and brings its contacts into the rest position. The counting rate ZS has then reached its rest position and is ready for further use.

The earth potential applied to wire ZK _{2 for} a short time via switching arm 4 of the pick-up -ABW and Sehäitarm 8 of counting set ZS causes the excitation of relay D ₂ in the money adjuster GZE: Earth, wire ZK ₂ , contact ϊΰβα ₂ , Winding I of relay D ₂ , battery, earth. The * relay D ₂ is placed immediately! Via its contact 149 d _s , winding II of relay D ₂ , contacts 150 m, 152 / or i-53j? “Earth, in a holding circuit. That

Relay D ₂ - closes its contact

and

thereby- for the magnet D _{10 of} the cash adjuster the following circuit: earth, contacts -1-54 d ₂ , 156 0, 1-59 ^ ₁ , Wickhing III of the relay R, -MagnetD ₁₀ , ^ battery, earth. The magnet D ₁₀ closes its contact 157O ₁₀ when it is excited, whereby the following circuit is closed for the relay O : Earth, Centakt ί'54ώ ₂ . Ϊ57 ^ ιο> winding of relay O, battery, earth. At contact 1560 the circuit that has just been established for Di _{0 is} interrupted, the relay O at contact 157 ^ _{10 is} switched off again and contact 1560 and thus the circuit for D ₁₀ is closed again. The game between D ₁₀ and O continues until the switching arms of the GZE money setter have reached their rest position. If this has happened, the following circuit for relay D ₁ is established via switching arm 1: Earth, contacts Ί54ίΖ ₂ , 157Ci ₁₀ , switching arm 1 in rest position, contact 172 f, winding I of relay D ₁ , battery, earth The ReIaIsD ₁ is immediately placed in a holding circuit via its contact 1670E ₁ , winding II of the relay D ₁₁ contacts i '$ om, 152 / or T $$ P> earth. The circuit of the magnet D ₁₀ is opened by opening the Open contact 159Ci _1. Through

Closing of the contact 15Si ₁ is brought to the solenoid D ₁₀ under the influence of an IQ-second switch which, at intervals of 10 seconds, the magnet D ₁₀ each time transmits an impulse, thereby incremented each time the contact arms 1 to 6 of the money adjuster to -a step will. This circuit runs as follows: earth, 10-second switch, contacts 168 t, i6ge, 161 c, 158 ^ ₁ , winding III of relay R, magnet D ₁₀ , battery, earth.

The money setter will namely, after having taken part in the finding of the correct one Contributed fee deposit and has done this task in a positive sense, according to Completion of this control process for another purpose, namely as a timer for time counting and for compulsory disconnection after a certain time, for example after 3 minutes.

If the money adjuster GZE has switched its arms 1 to 6 to the 17th contact under the influence of the _{10 second switch, the following circuit is closed, i.e. after 170 seconds: Earth, contacts 154 ^ 2} , ¹ Sy ^ iO; Schaltarm'ι of the money adjuster GZE, contacts 17, 162 ^, winding of the relay from ₁ battery, earth. In this circuit, the relay Ab responds and switches on the contact 172 from the busy buzzer to the cores α and b leading to the payphone and thus gives the speaking participants the sign that the speaking time has almost expired. If the participants ignore this warning signal, when the switching arm ι has reached the 18th contact, i.e. after 3 minutes, the following circuit is closed for the relay Bes : Earth, contacts 154J ₂ , iS7 <iio> switching arm ι of the money adjuster GZE , last contact of the contact bank marked by it, contact 170 ^ _1. , winding III of the relay Bes, battery, earth.

The relay Bes closes for itself at the contact 63 bes a holding circuit running through the contact 61 p, winding I of the relay JIi, winding I of the relay R to the battery, which, when the relay P is energized during the checkout process, at the contact 61 p is opened. By opening the contact 2>& bes , the c-wire in the preselector 1 ^ W is interrupted, thereby giving the signal to trigger the connection devices and causing the relay T to drop. By opening the contact 32 1 , the holding circuit for the two windings I and II of the relay F and the relay R is separated.
The collection of the coins and the

Transfer of the facilities to the idle state takes place in exactly the same way as was described for the establishment of local connections. It should be mentioned here that at the moment the relay P is registered and energized, the hold circuit for the two relays D ₁ and D ₂ , which have participated in the time counting, are brought to waste by opening the contact 153p.

Let us now consider the case that the calling subscriber is responsible for the desired Connection due fee is paid not with one, but with two types of coin. It again assume that a connection is desired for which a charge of 70 pfennigs is charged, and that the calling party receives a 50 pfennig ^ piece and two ioPfennig ^ want to deposit pieces. The coins should, no matter what type of coin they belong to, in one and the same coin slot The order in which the coins are inserted is arbitrary. Be it Therefore, it is assumed that the participant first receives a 10-pfennig piece, then the So-pfennig piece and finally another 10-pfennig piece. Throws in a penny piece.

When throwing in: the first io-pfennig piece, the magnet D _{10 is} influenced, as has already been described in detail for Ortsyerbindungen, which thereby brings its switching arms 1 to S to contact 1. If the 50-pfennig coin is now thrown in, it is directed to another path than the one-pfennig coin, also after the coin tester has checked it for suitability and authenticity. The contact 1 g ₅₀ , which is briefly opened during the falling movement of the 50-pfennig piece, lies in this path. As a result, the relay G _{50 is also} dropped for a short time. The relay G ₅₀ closes the contact i8g ₅₀ when it drops, which creates the _{following circuit for the relay D 1} : earth, contacts 22 an, 20 p, 1Sg ₃₀ , 16Od ₁ , winding I of the ReIaIsD ₁ , battery, earth. The relay D ₁ immediately closes a holding circuit via its contact 167 ^ ₁ , which via its winding II, contacts x ^ o / yn, ¹ SS? runs to earth. By opening the contact 3Od ₁ , the switching arm 2 of the money adjuster GZE, via which the zone testing process took place in the connection described above, is switched off and by closing the contact ^ p ^ the switching arm 3 of the money adjuster Si via which the zone testing process now runs is switched on. If the participant throws in the second 100 penny piece, an earlier mentioned circuit for the T) rehmagnet D _{10 is} closed _{by interrupting the circuit for the relay G 10} and closing the contact 16 g _10. The switch arms 1 to 6 of the cash dispenser are thus transferred to the second

clock switched. The contact 2, to which the switching arm 3 is set, is also connected to the zone rail 4, as can be easily seen from the drawing. The zone check is therefore carried out in exactly the same way

As in the case when the speaking guest pays with seven io-pfennig pieces ^ only with the difference that the earth potential required for the excitation of the relay G in the zone tester is now via switching arm 3 of the money adjuster GZE and the contacts _{29d v} , 23, 2i applied to 2 d _2, 2ζ% /. The processes in the zone tester and in the counting set ZS are exactly the same. ... . . :

The ReIaIsD ₁ , which in turn has to participate in the time counting, is brought into the rest position before the start of the time counting in the following way: After the relay G in the zone tester ZPR has been energized and "2Q this is in a holding circuit (via contacts 92 g -, 93 h) had settled, short time thereafter, the contact 84 ^ ₂ is closed and thereby applied ground potential to the switching arm II of -Mitlaufwerkes MWI .and the SchaltarmII of Mitlaufwerkes MW II This is the money adjuster GZE of the winding II.. Relay M. closed a circuit that runs as follows: Earth, contact 84 ^ 27 winding II of relay G, switching arm II of the follower works MWI, contact 7, Sehaltarm II -des follower works MWII, contact x, - busbar 44, switch arm 4 of the connection finder VS ,. Zone rail 4, switching arm 3 of the cash adjuster GZE, contacts. 29 J ₁ , 28 ^ ₂ , 25 ^ 24 / (the relay F - was, as described above, excited by the zone tester), winding II of relay M, battery, earth e. The relay M opens its contact 150w and thereby opens the hold circuit of the relay D ₁ . This relay drops out and can now be used for the time counting process that now follows. -. . ": .-" .-

Let us now consider the case that a remote call is desired for which an amount of 1.20 MJi is to be paid. The participant has the option of paying this amount in three ways:

_o i. By! Throw in twelve io-pfennig pieces

- Each time with Einw-urfeinesio.-Pfennig-Stükkes, as already described, the contact ² ITiO is opened and thus the relay G _{10 is} brought to waste for a short time. The magnet. D ₁₀ ■ obtained by closing and opening the

• Contact i6g _{10 has} twelve current surges and adjusts its switching arms to the twelfth contact. The zone rail 6 is connected to the twelfth contact of the contact bank exposed by the switching arm II of the cash adjuster GZE. The code number for such a connection naturally has a different composition than that for the remote connection described above. As a result, the shared drives MW I and MWII are set in a different way in the zone tester ZPR. The zone testing and excitation of the relay G then takes place via the switching arm II. Of the follow-up works MWI and an arm of the follow-up works MW II, for example in this case the arm III, which is then on a contact to which the busbar 66 and also the Switching arm 6 of the connection finder and the zone rail 6 is connected. The zone test procedure is otherwise carried out in the same way as before.

2i By inserting a 50-pfennig piece _go . "'And seven io-pfennig pieces

If a 50-pfennig piece is thrown in, the magnet D _{10 is} not influenced, but the relay D ₁ , as explained above, is activated, thereby switching on the switching arm 3 of the money adjuster GZE and using it to carry out the zone check. By inserting the seven io-pfennig coins, the rotary solenoid D ₁₀ receives seven current surges and switches its switching arms to the seventh contact. The contact 7 of the contact bank marked by the switching arm 3 is now also connected to the zone rail 6, so that the zone check is carried out in the same way as for the entry of twelve io-pfennig coins, with the difference that that Equalizing potential for the relay G via contact 29 O ₁ and to the switching arm 3 of the .Geldeinstellers is applied.

3. By inserting 2 χ So-pfennig pieces and two io-pfennig pieces

When the first 50-pfennig piece was thrown in, relay D ₁ was activated, as explained above. If then a second 50-pfennig piece is thrown in and thus the contact 18 g ₅₀ to the. Closed the second time, the _{following circuit is created for relay D 2} : earth, contacts 22 an, 20p, 18If ₅₀ , 173-d'i, 164 <2 ₂ , winding I of relay D ₂ , battery, earth. The relay D ₂ immediately closes a hold circuit, which runs to earth _{via contact 149J 2} , winding II of D ₂ , contacts 150 w, 153 ρ. When D _{2 responds} , contact d. ₂ . opened, .due the switching arm 3 of the zone tester off, and switched on by closing the contact 27 d _{2 of} the switching arm 4 of the money adjuster. In this case, the zone check takes place via the switching arm 4 of the cash adjuster. Now are the still required two io-pfennig pieces

62? 197

thrown in, the magnet D ₁₀ switches its switching arms to the second contact. As is readily apparent from the drawing, the contact 2 of the contact bank swept by the switching arm 4 is also connected to the zone rail 6. The zone test is carried out again in exactly the same way, with the difference that now the response to relay G in the zone tester ZPi? required ground potential is applied via contacts 21 , 23 f, 25 η, 27 d ₂ , to switching arm 4 of the cash adjuster, contact 2 and zone rail 6.

The relay D _t and D ₂ , -the one at the throw-in.

The 50-pfennig pieces are then actuated in turn by the excitement of the Relay JIi, as previously described, brought to waste and used to count the time used. <

The zone test is carried out, as can now be easily seen,

1. If only io-pfennig pieces are thrown in via switch arm 2,

2. when inserting a 50-pfennig piece alone or with io-pfennig pieces at the same time.

tig 'via switch arm 3,

3. If two 50-pfennig pieces are thrown in alone or with other io-pfennig pieces at the same time via switch arm 4.

The switching arms 5 and 6 of the cash adjuster GZE come into effect during the zone test during the night tariff, that is, when the contact 25 η is open and the contact 26 η is closed.

i. If only io-pfennig pieces are thrown in, the zone test is carried out via arm 5, earth potential is applied via contacts 21 cw, 23 /, 26 n, 17Od ₂ , IJ / 'U ₁ , switching arm 5, etc. . .

2. If a 50-pfennig piece is thrown in alone or at the same time as io-pfennig pieces, zone testing is carried out via contact arm 6, earth potential application to excite G in zone tester ZPi? via contacts 21 an, 23f, 26η, i76d ₂ , 17Sd ₁ , switch arm 6 etc.

Let us now consider the processes that occur when the subscriber connects establishes, but does not pay the fee prescribed for the connection.

i. If a speaking guest tries to establish a connection without inserting coins, since the switching arms of the money adjuster GZE remain in their rest position, a circuit for winding III of the relay Bes is immediately closed when the receiver is lifted: Earth, contacts 21 on, 23 / , 25 n, 28 d ₂ , 30 dl, switching arm 2 of the cash adjuster GZE in the rest position, contact connected to relay Bes , winding III of relay Bes, battery, earth. The relay Bes responds and transmits a busy number signal to the subscriber by closing contact 175 of the. At the same time, the contact 38 is opened besides , thereby making any kind of connection impossible. -

2. What happens if the speaking guest pays an amount that exceeds the fee for the connection to be established does not match?

If the participant inserts too few coins, in this case there is a discrepancy between the two switching mechanisms, zone checker ZPR and money setter GZE , such that a certain zone rail is grounded via one arm of the money setter GZE according to the amount thrown in, but on the other hand the switchgear MWI and MW II of the zone inspector set by the code numbers according to the traffic direction occupy such a position that the earthed zone rail cannot be reached via these switchgear. The circuit for the correctness of the fee payment ascertaining relay G can now not come into being in the above-mentioned circuit. As a result, contact 94g "in the zone tester ZPR remains in its rest position, while contact 60 h of relay H, which was energized independently of relay G , is closed. This creates a circuit for relay Bes: earth, battery, contacts 94g ·, 60 h, switching arm 8 of the connection finder FS, wire r, contact 47 m (Fig. R) (the relay M in the money adjuster GZjB was brought to waste by opening the contact 59 h in the zone tester ZPR ), winding II of the relay Bes earth. the relay Bes again turns off the busy signal to the speech wires of causes open by des.Kontaktes 386 is die.xoo triggering the previously set communication facilities and prevented the completion of the connection. through the relay Bes so one already under construction Connection at the moment when it is established that the money deposit on the payphone has not been made correctly or that codes and thus traffic directions have been dialed that were not the one that was inserted n amount, interrupted and the connection devices set up until then released.

If the subscriber hangs up his receiver after receiving the busy signal, since the relay E determining the collection of the amount has not yet been energized (relay /?

_r The solution of this object is of 'Her drawing immediately apparent ,. If four individual io-pfennig pieces are thrown in; ,, the switch arm 2 is opened. the contact4 and thus to the. Zone rail 3 is set, via which then! the zone test takes place. If a SovPfennig piece is thrown in instead of the four individual io-pfennig pieces, - sa is thrown in through the contact 29 "(A ₁ and break contact of the contact bank crossed by the switching arm (as already described," yes The switching _{magnet D 10} does not affect the switching arms; the cash inserter remains in their rest position) also ^: the zone scene 3 is switched on, so that here too the zone test is carried out in a positive sense; can rar the same way as via switch arm 2 when inserting four io-pfennig pieces.

The same applies if the amount of τ 91Jt is paid in for a connection instead of 90 pfennigs. If the participant pays with nine individual io-pfennig pieces, Zöirenprüfung via holding arm 2 of the cash dispenser, KontaM 9 of the contact bank and zone rail 5. The payment is made with one 50-pfennig piece and four io-pfennig pieces. the switch arm j of the cash adjuster GZB is switched on at contact 29 ^ ₁ , and “the switching arms of the cash adjuster are set to the fourth contact.” Zone rail 5 is also located on this contact the contact 27 ^ _{2 is} closed and thus the switching arm 4 is switched on. In this case, switching of the switching channels 1 to 6 by the switching magnet O ₁ Q does not take place. The normally closed contact on which the switches * 4 stent is also connected to the zone rail 5. In all three cases, the zone test is carried out in the same way via the zone rail 5, the only difference being that the earth potential is applied once via the switching arm 2, then via the switching arm 3 and finally via the switching arm 4.

The control of the relay N indicating the entry of a new tariff can, as mentioned, take place by a clockwork arranged in the exchange. However, in order in a large network with many exchanges on the one hand: to avoid such movements by Möglichfoeit uniform, on the other hand for the whole network ^to:. To determine the occurrence of a new tariff in all exchanges at the same time, the switching devices determining the occurrence of the tariff change can only be arranged in a main exchange, while the switchover to a "different tariff in the

individual exchanges automatically from this main exchange from by remote control over existing, the speech traffic serving connection lines takes place.

Patent claims: i. In telephone systems in which different-valued Connections made ίο, the respective tariff (e.g. day and night tariff) characterizing switching devices (N) in the exchange on the different value of self- loads of the connection points determining devices (GZE) so that they bring about this in a way corresponding to the respective tariff by self-loads Switching dimension machines of the microphone units can be controlled. 2. The switching devices according to claim ι simultaneously control a tariff indicator (SG) at the speech stations (MF) with self-loading devices. 3 * The switching devices according to claim ι simultaneously control switching means (ABW) which influence registration devices (ZF) to determine all total loads on a connection point. 4. In telephone systems according to claim i, in which the value of the respective self-exposure is determined by the identification of certain identification lines (zone rails 1 to 6) on the part of the detection devices (GZE) , the same identification lines are used for the different tariffs to identify different values (e.g. zone track 2: 30 Pfennig daily fee, 20 Pfennig additional fee). 5. "In telephone systems according to claim i, in which switching mechanisms (D ₁₀ ) are used to determine the value of the self-loading, these are equipped with several switching arm sets (2 to 4 and 5 to 6) for the various tariffs, one of which is through the Switching devices that determine the respective tariff are switched on (at contacts 25 n, 26 n). 6. In telephone systems according to claim i, which consist of several exchanges, the switching devices (N) determining the occurrence of the tariff change are only arranged in one or in a few main exchanges and control the switching devices provided for speech stations with self-loading devices via existing connecting lines serving for voice traffic.
