Description

Dialers are already known in which the dialed number is marked by turning the levers corresponding to the number digits, and the pulses are sent by turning the eccentrics driven by a mechanical engine, and the number of eccentrics will not determine the numbering system of the telephone network.

The present invention consists in the constructive implementation of such a dialer and aims at reducing the time for dialing, realizing the possibility of checking the dialed number, changing the speed and rate of pulses, and also realizing the possibility of automatically dialing a series of numbers.

The proposed dialer uses a number of already known structural elements, such as snail-shaped clowns with teeth, stopped at the right time with a spindle pulled out according to the number, as well as known techniques, such as changing the number of pulses per second by changing the speed of rotation of the engine and etc.

In FIG. 1 depicts

General view of the dialer from the side; FIG. 2, a front view thereof; FIG. 3 is a vertical section and FIG. 4 is a view of the dialer part along the arrow a in FIG. 3

Main axis 3 dialer.;. is driven in rotation (e.g. at 40 rpm) from the motor. On axis 3, the axis 2 is placed on the floor, which, before starting the dialer, remains stationary iodine by the action of the coil spring 4.

On axis 2 are located eccentrics 5 (according to the number of digits in the number). These eccentrics can rotate freely on axis 2 and have the shape of a cochlear ratchet (Fig. 3 and 4). In axis 2 there is a gap of transverse slits (approximately, on; 3), in each of which a tooth of 6 core 7 is hinged, hinged together in an eccentric 5. Anchor 7 has three outlets, one of which ends with tooth b, the other abuts against a flat spring 8 fixed on the same eccentric and fixing measles either in the resting position or in the working position (the tooth 6 completely fits into the slot of the axis 2), and the third in the resting position of the core enters the clip 9 fixed on the support shelf 10, which in turn, it is attached directly to the wall of the case.

On the same axis 2, a collar 77 is fixedly fixed, which, when moved counter-clockwise in FIG. 3 with the help of the pawl dog, the ratchet is fastened with the ebonite impulse wheel 72.

This last, in the same way as in a conventional dialer, acts upon pulse contacts 13 and upon returning axis 2 with a buckle to its original position is fixed in place by means of brake springs 14.

A movable pin 75 is located near each eccentric, which can move towards the eccentric using a plate 76. The pin returns to its initial position by the action of a helical spring 25. The six such plates 16 are fixed hingedly on a fixed axis 77 and have on the edge of ten cuts each of which is more than the previous one removed from the center of the axis. Thus, with the aid of the handle 18, the plate 76 can be turned at a certain angle, and the corresponding pin will thus be more or less pushed towards the eccentric.

The position of the handle is indicated by the arrow 19 on the dial, which has a number of rows (for each handle, one row with ten digits (from 9 to 0).

The entire dialer is enclosed in a metal case or made of plastic, on the lid of which the said dial is placed.

As a source of movement in the dialer, a gramophone type motor with small dimensions and weight can be used, and due to the presence of a centrifugal regulator, it is sufficiently stable to maintain a certain rotational speed, which is controlled within known limits.

If necessary, a spring mechanism can also be used as an engine, which is set in motion after the plant before the cal {smoke dialing number).

The required speed of axis 5 is achieved either by adjusting the engine or by an appropriate gear.

The action of the dialer is as follows. The knobs set the required number on the scale located on the cover-case, and at the same time the engine is turned on so that at the beginning of the set it rotates at the required speed.

Depending on the dialer's application, whether the subscriber’s apparatus, the telephone operator’s workplace, or the transparent table, the engine can be turned on manually or the engine can be automatically turned on at the beginning of dialing and off when dialing is completed. The possibility of continuous rotation of the engine in the event of increased use of a dialer, for example, at an intercity station, at intermediate tables, etc., is also not excluded.

The dialer itself can be launched either by pressing a button after the PBX signal appears in the telephone, or automatically using an electromagnet (not shown) that works, replacing the button when the register is connected to the line equipped with the dialer described .

A button or a measles electromagnet presses the measles 7 of the first eccentric 5 on the left (that is, the corresponding first digit of the dialed number), with the tooth b core entering the slot of axis 2, and its third process extending from its clamp 9 (see Fig. 3, where for convenience of observation a part of the eccentric is cut out and a tooth 6 and a slot in the axis 2 are visible). Spring 8 fixes this position.

In axis 3, rotating in the direction indicated in FIG. 3 with an arrow, there is a longitudinal key 20, in cross section having the appearance of a flattened tooth. When the key 20 fits with its beveled part to the tooth 6 of the core 7 of the first eccentric, it will carry away

is this tooth, and therefore eccentric. At the same time, axis 2 begins to rotate as well, as tooth 6 rests against the end of the first slot of this axis. All other eccentrics will remain in place, as their measles will be held in place by clips 9.

Thanks to the clamp //, as mentioned above, the impulsive wheel / 2 will start moving and will start to give impulses, the number of which depends on which way the impulse wheel has time to pass.

The movement of the first eccentric 5, and with it the entire system (axis 2-collar / 7-pulse wheel / 2) will continue until one of the teeth of this eccentric rests into the projecting end of the pin 7.5. Since each succeeding tooth of the eccentric is removed from the center of its axis more than the previous one, the path that the eccentric will manage to pass depends on how far the pin 15 is pushed forward and, thus, on which number is set by the handle 18. If, for example, a rake was assembled, then the fifth tooth of the first eccentric is pinched in the pin 75, and the impulse wheel will give five impulses during this time.

As soon as the eccentric stops, the key 20 of axis 3, while continuing to press the bark 7 with its beveled part, pushes this tooth out of the slot of axis 2 and this latter, due to the action of the coil spring 4, will immediately begin to return to its original position (the axis 3 will continue its rotation in the same direction).

At the same time, the eccentric will also return, as the tooth b does not fully exit from the slot, and the end of the slot will carry it along with the bark 7 and the eccentric (see, Fig. 3).

When the first eccentric is returned, the pin 27 located on the second core of the process 7 and passing through the oval holes of the eccentric will meet with the beveled protrusion 22 located on the second process of the core 7 of the subsequent (second) eccentric. Push this

the protrusion, the tong 27 will force the measles 7 of the second eccentric to occupy the working position, since the second process of the core will rise to the right (Fig. 3), and the tooth 6 of this core will go into the slot of axis 2.

The interaction of the pin 27 and the protrusion 22 is also visible in FIG. four.

When moving forward the first eccentric, the pin 27 and the protrusion 22 of the next core did not meet, since the measles of the first eccentric was in the working position and the pin 27 bypassed the protrusion 22 on the right side (Fig. 3).

Thus, after returning to the initial position, the first eccentric triggers the next eccentric, and the entire process described above repeats again, whereby the pulse wheel gives a new series of pulses, respectively, to the second digit of the dialed number.

Then the third, and so on, eccentrics will be used until all the digits of the number have been dialed.

Tension of the coil spring / and other elements of the structure must be chosen so that, firstly, axis 2 in any case returns to its original position earlier than key 20 in its movement approaches tooth b for the next process and, secondly, the dynamic force created when the axis 2 returns in any case (with the smallest rotation of this axis in the previous process — set of units) was sufficient to transfer the box of the subsequent eccentric to the working position.

The shunting of the conversational circuit at the time of sending pulses is carried out as in a conventional dialer, using special shunt contact 23 (in Fig. 3 for not shown) and the corresponding pin on the collar 77.

When recruiting special lines, as is known, a combination of only two digits-zero and any other is needed. In order for the dialer in this case not to send an excessive series of pulses, a special device has been introduced into the device, the description of which is given below. In the bar on which the pins 15 are located, the curved lever 24 (Fig. 2) is pivotally fixed, pulled away by a spring 25. If the first digit is zero when the number is dialed, then the special protrusion on the first left plate 16 when translating the first handle 18 to a digit It will push the lower end of the lever 24 so that its second end enters the special cutout of the third eccentric 5 and slows it down.

The set of the first two digits will occur normally, and when the key 20 approaches the tooth 6 of the third eccentric, nepei dedented to the working position when the second eccentric returns, it will encounter resistance (the eccentric is inhibited) and slide it to its original position.

Thus, the sending of pulses will stop there.

The dialer is described above in a form in which it can be installed at the work station of a manual station or at a subscriber during similar work.

Using it for special purposes (for testing equipment of the PBX) requires the introduction of some devices not shown in the drawing.

Thus, for example, an automatic change in the speed of sending pulses is achieved by introducing a special electromagnet at the engine, which, at the required moment, triggers an additional felt plug (other than that pressed by the main regulator) to the adjusting disk of the engine. By adjusting the course of the core of this electromagnet and the main regulator, one can thus obtain two rotational speeds from the engine, which automatically change when the electromagnet is turned on.

The automatic change of the pulse coefficients is achieved by introducing an additional pair of pulse springs into the pulse wheel 12, which are adjusted so that the pulses are obtained with a different coefficient.

The main and auxiliary impulse contacts are switched at the required moment in accordance with the circuitry of the test instrument.

The automatic replacement of one number by another is achieved as follows. On the smallpox 17, instead of the plates 16 with the handle / (), are placed the throat of the shields having ten radial cuts of different depths, depending on the digits of the given numbers. The washers are fastened to each other and to the ratchet wheel having ten teeth that rotate with the help of an electromagnet that has a doggie on its cortex (like a seeker).

Pins / 3 fall into the recesses of the shields at different depths, and this creates the necessary digital number combination.

When an electromagnet is triggered, all the shields are rotated by one tenth of a circle, and P1-types fall into the other notches, creating the next numerical combination of the ten preset ones. If you wish to replace these ten numbers with other points, they may be shifted with respect to each other or replaced.

The dialer, installed at the subscriber, may also have such washers on the axis / 7, and in this case they will already be rotated with a handle with a pointer installed against the signs placed on the shchka. subscribers

The maximum number of specified numbers depends on the size of the washers and can be determined with the constructive detail of the device.

In addition to the options for using the proposed dialer already mentioned in the description, it is also obvious that it can be used on commutators that are connected to PBX, long-distance switches for communication with urban exchanges, on any kind of intermediate tables, etc. Using the dialer greatly simplifies the work of telephonists, shortens the subscriber service time when connecting it to the PBX, and eliminates

useless register delay. The dialer can replace the keyboard, and can be installed not only on the PBX itself, but also on ia of any manual station associated with it.

Manipulations when using the dialer in this case allow the telephone operator, do not wait for the PBX signal, you can dial, disconnect and go to the service of the next subscriber, the dialer itself when the PBX signal appears, dials the number itself.

If the called subscriber is busy, the call can be repeated any number of times without any additional work on dialing, since the required number has already been set up (if during this time the dialer was not used to dial another number). Due to the fact that dialing begins immediately after register connection, the dialing time is significantly reduced, and the accuracy of dialing all digits of the number is achieved, eliminating unproductive register work and repeated orders; According to the author, the coefficient of the use of the register of ATS can be increased to 100%.

The dialer should also be used for all sorts of training and test works in the operation of ATS (cord testing, control of the number of failures, etc.). In this case, the most cumbersome and difficult part of the work of dialing is eliminated, and it is possible to automate all the work.

The subject matter of the invention.
