I In the upper part of the casing p of the machine, there is a hole / (figs. 4 and 5), fitted to lower the gchoneta of a certain merit. Hole / joint. Ts with a sloping channel A, leading to the outside of the cup D and equipped with an adjustable screw J, f, with a slanting direction of the coin in kEnad C. c, the third channel B, and also leading to the chalryk D: for this channel C has

- a stop formed by the core T of the electromagnet / installed inside the casing and a slot connected to channel B. When the microphone is picked up, this slot is covered by a plate d connected by a rotary lever T with a lever mic {ertele / / background (Fig. 4 and 6). When the microtelephone is hung on the lever, the hole opens (Fig. 7). The induction cable and the capacitor, shown in dotted lines, are attached to the top of the machine. Terminals n serve for connecting the device to the three linear wires a, c ,. 6 (FIG. 1) and ground, and terminals L serve to turn on the handset. The device is equipped with group buttons A, B. To avoid uneven distribution, neither coins in the piggy bank (formation / slides and no longer access of coins to the piggy bank when filling it from one side only) the piggy bank channel is made so that when the coins get stuck in the hole qi again lowered coin. can pass into the hole q, is filled in this case, the left side of the ko. sawing. Cuts D are made along channel j4, B and C, which serve to push out the jammed coin lice without having to open the channel. Channels A, B and C can be used for 10, 15 and 20 kopecks if they are designed for; most of them (20 k.). Right;

The action of the machine in all three cases is achieved by installing a larva of the appropriate size above the hole /, installing the adjusting screw / and moving the electromagnet / (up or down, depending on what payment is made for using the coin machine). The circuit for switching on the automaton (Figs. 1 and 2) has been drawn up in relation to the conditions for allocating special switch positions for servicing the coin machines. The servicing of automatic telephonists does not differ from the service of real subscribers.

- When the telephone is hung, the line is switched on to the capacitor. When off-hook and in the absence of a coin in the channel, the microphone circuit in contacts mi and t2 will be open. To call the station, the subscriber picks up the phone from the lever of the device, lowers the coin of the corresponding denomination And in the same way also stops Kak when using the O & T device. If the coin is larger than the required size, then, due to the size of the blocking hole / larva, it cannot pass in. MoHeVa will be rolled along the lower edge of the channel L and will not touch the adjusting screw by inertia, will slip through the opening of channel C and go out into the cup D. If the coin is lowered into the channel, the size is the required one, then it will hit the adjusting screw / will go into channel C. VcanaleS it will reach the stop formed by the core t of the electromagnet S, and, when raised into the contact spring t, will connect it to the spring t. The small coin, even if it enters channel C, will not be able to close the springs mi and Otz and scat In the piggy bank. Since, when the tube is picked up, channel B is closed by plate d, the coin in channel C will close the microtelephone circuit by it, and will remain in the position shown in the figure by a dotted line only until the electromagnet has operated (the connection with the required subscriber was established) and release the coin path into the piggy bank (while the springs mi and W2 will remain in a closed position under the action of the electromagnet core).

or until the handset is hung (in the case of a failed connection), as a result, the passage to the channel is opened.5 and the coin is thrown out, through channel 5, into the plate D (the subscriber receives the coin back).

After receiving the call, the telephone operator of the corresponding group inserts the test plug O. ZZ /. Into the socket and, as in the normal scheme, separation relay No. 3, connected in parallel with separation relay РК24, comes into effect. Relay Р№ 4, due to insufficient current, to pull your own. measles can not. When this, relays # 1 and rel4 KO 3 are triggered. Closing contacts 1 - 2, relay # 3, apart from the formation of normal chains of burglar lamps, causes the operation of a slowly acting relay # 8, which prepares additional circuits for further work. When interrogating the subscriber in the automatic machine, all the devices are in the position preceded by the interrogation, i.e. the electromagnet measles / is in the rest position and the coin is in the channel. If the desired subscriber is busy, the tube is hung on the lever and the coin returns through the cup D in the manner described above. -

When making a call to the required subscriber, if he is not busy, supplying the inductor current to the keys occurs via an additional relay J42 7. The number of these relays Corresponds to the number of keys. Relay No. 7, having caused its measles under the influence of excitation with inductive / winding current O, locks itself through the second winding, which, being connected to the pole of the battery, connects the second end of the circuit: its contacts 3-4, to minus. If the called subscriber does not respond, the burglary relay / No. 2 remains at rest and in the circuit of the interrogation cord the operation mode remains I unchanged. In this case, the telephonist informs the person using the coin machine that the callee does not respond; the caller hangs up the phone and gets the coin back. If the called subscriber responds, then relay No. 2 is activated and, in addition to the normal opening of the bounce lamp circuit, the contact springs 1-2-3 are formed; the following circuits form: 1) batteries, contact 2 - 3 Wol relays, contact 1-2 relay No. 2, contact 5–6 relay We 7 and contact 3--4 relay No. 8 to O. Sh .’s housing, through closed contacts 1 –2 time relay No. 9; 2) batteries, contacts 2 - 3, relay No. 1, contacts 1-3, relay No. 2 are not valid, and the relay winding is L 8. Connecting the negative pole of the battery to the case of the test plug on the first of these circuits causes the relay drive current to increase P number 4, which at the same time triggered and shorting

:: Of their contact springs 1-2 creates circuits for an electromagnet / and for counter P no. 5. An electromagnet / connected at one end of the winding and a positive noTirocy battery (ground) will be connected via wire A to the negative pole of the battery stan | diy. Due to this, the electromagnet / will work, it will pass the coin in and will close its contact springs with its core, t - Otg; the spoken goal will be closed and subscribers will be able to talk. The second of the aforementioned 1x circuits feeding the negative pole of the battery on

the inactive winding of relay No. 8, the active winding of it will be bypassed. Relay 8 will release the measles and interrupt the circuit connecting the negative battery pole to the plug case. Thus, in conversational. The numbers of subscribers will remain on when the transformer relays are turned off. No. 3. When through relay P No. 4 again a small current will flow. Relay No. 8 is made slow-acting so that the relay I No. 4 has time to work within a period of time from the moment of shunting the operating winding of the relay 8 to the moment of opening its contacts 3-4. Relay number 7, is intended to ensure that the passage of the coin to the piggy bank was impossible without sending a call to the line (if the called subscriber closes the line, the plug will trigger the signal when the plug is inserted, and the telephone operator does not send the call per line, will cause the caller 6 line damage).

When an abantenta i is called i, relay No. 8, as can be seen from the previous description, releases the message

your contact springs 1-2. At the same time, the relay is in the working position —and closed contacts 1 - 2. It includes the winding of relay No. 9 on the pulsator. Thus, from the moment the called subscriber answers, time relay No. 9 comes on. The pulse machine pulses are designed so that after three and three minutes, the time relay contacts are opened, due to which the interrogator circuit Q. 4 release your measles and open the electromagnet circuit. The latter, releasing the measles, opens the microphone circuit and the conversation between the subscribers is interrupted, - Since the burglary relay No. 1 loses the supply current, it releases its measles through the contacts 1–2 liters of the 6th negative pole; batteries to the flashlight O.L. and to the second winding of the time relay. The latter, by bringing its own measles, will free the cog wheel / which will return to the initial position. In addition, having lost the shunt again, it will enter into operation the relay No. B and: open the time relay circuit by disconnecting it from the pulse machine. Lowering the additional coin (if you wish to continue the conversation) will activate the burglary relay No. 1 and again create conditions for the PMA 4 relay (connecting the negative pole-correcting plug to the case O.Sch.}. -Relay P # 4, having pulled, measles trigger electromagnet / and the conversation between subscribers can again continue for three minutes, as with relay No. 8 again, they can get rid of their measles and turn on the relay time No., 9 He pulse device. The number of passed coins in the coin box is made counter P number 5. After the day is triggered every time; as soon as the relay P No. 4 operates, this relay can only work when the coin in the channel nd closes, the contacts t, and tg, in the device. In the absence of this contact (no coin), the relay circuit I 1 will be is open and therefore the net minus will not be fed to the interrogator's case, which means Rale R No. 4 will not be able to work.The electromagnet / may work and give an opportunity to talk to the subscribers only if there is a coin s

Chanale, and therefore only with. passing it in; piggy bank. In this way,

: every passing of a coin in will. match; counter operation. The counter P N ° 5 on the de disk with a tkrv has a protrusion that, with a py: but; m, reverse it, i.e. during the passage

: one hundred coins, closes, contacts 1, and 2, which causes the connection of the negative pole of the battery (for

l disk movement from the extreme position to zero); to, the winding of the relay current. The distributor C / Kol through the springs

buttons / s. Since one end of the winding rex (e 7 № 1 attached to the positive terminal of the battery is permanent, it

- there is no measles and will move the brushes - the distributor one step. When In the piggy bank; it will be missed, a thousand coins, a counting disc will make ten turns and, accordingly, the current distributor's brush will become the tenth contact and attach a negative

pole: battery to signal lamp. Pressing the K button of the current distributor is brought to the zero position, since in this case its winding switches on through the rings of chain 2 on the relay P No. 5. After the piggy banks are removed from the coin-operated machine, the station’s personnel, having received a notification, puts the / С button back to the normal position and the power distributor, pzet into action.

Modification of the switch-on circuit of the automaton isoberg in FIG. 8 and 9. In this case, the time limit for negotiations is somewhat different. After the called party answers (the moment the conversation begins), relay No. 8 releases its measles (see the description of the action according to the first scheme) and turns on the current winding; Limiter UN ° 2 through its contacts -2 and contacts 1-2 relay No. 7, n, and pulstmashina. If a full turn of the current distributor is reached, for example, by twenty five times by moving the brushes (each time by one step), then the pulses must be fed approximately every 7 seconds. By the end of the third minute,

, mrm) ent | a start of the conversation (seconds) will be in the twenty fifth position A. (M ..

Ufc -i -.,. “..

In this case, the circuit, going from the opening of the transformer relay to the housing of the questionnaire, will be open. Thus, (as was described above for the scheme in which it is applied, the time relay), the conversation between the subscribers will be interrupted. Breaking the rampage; the thief between subscribers, the distributor goes to the position no longer under the action of the pulse mask, but under the action of the pulse relay No. 10, the circuit that is connected to the current distributor winding closes through pin 1-2 of the relay No. 9 (the last action takes place immediately after the conversation is interrupted) Is the zero-current distributor stop working, since its winding circuit in the direction of the nyj bc-relay in the ring rings 7 and in the direction, the pulse maschine in contacts 1-2 of the relay number 8 will be unlocked.The addition of an additional coin causes 11 prod False talk between subscribers and launching a current distributor (1 to 3 minutes) through a pulse machine. If subscribers end the conversation earlier than 3 times, the current distributor goes from zero to the third. is reset.
