Description

The main patent describes a telephone automatic station with the use of a sectoral device, which has the form of an endless belt and: equipped with interconnected sockets. The sockets are located along the side of the penta and are intended to form contact between the plugs of two connected telephones. The plug is pushed into the socket by two electromagnets. The present invention relates to said device and is a modified form of its implementation.

In FIG. 1 shows a device diagram; FIG. 2-form of its implementation with the use of slip rings; FIG. 21 is a partial cross-section of the device of FIG. 2; FIG. 3-room selection mechanism; FIG. Z-cross section of this mechanism; FIG. 4 is a wiring diagram of number sampling and FIG. The diagram of the device during the operation of the dial of the electoral mechanism. Each pair of electromagnets 1 and; 2 is replaced by one electromagnet 1 (FIG. 1). To contacts 39 and 39i summed one pole of the battery I. to contacts 41

to 4: 11 is another position of this battery, and contact 40 is connected to resistance 413. When these contacts are switched, the currents of different polarity are sent to the circuit by washers mounted on the shaft of the electric motor 32 and having, around the circumference, the bevelled part. Electromagnets 1 are included in the local current circuit only when the linear finder is operating and are actuated by the coil of the electromagnet 12 as a longer reverse current passes through it through the use of a double core 14 (Fig. 2), one of which has ledge To include an electric magnet 1 in the battery circuit I c. two pins 33, located w; ees under lever 33-, with which they close.

Contact rows 25 (Figs. 2 and 2) are closed in the order of their numbers with slip rings 44 located along the edge of the tape 24; the number of the latter is equal to the number of rows of nests in each group; through the designated rings, slides; wands 44i, the other ends of which can be switched from the talker battery to the ringing devices, which is mainly necessary for the first row of contacts 35, opposite the plugs 6, and the second one above it. Switching is performed by contacts 44 and 44 located along two screw lines on the surface of the roller. The roller is rotated from the shaft 23 at a speed of one revolution during the passage of the set of contact rows; the current to contacts 44z and 44 is supplied through contact rings 44 located on the roller, adjacent to buzzer 70 and transformer 43; in a quiet state of the brushes 44, with their second ends, they adjoin the choke coils 43. The number-selective mechanism at the subscriber's telephone (Fig. 8) has the following parts: a short-pulse-sensitive electromagnet 45 with anchor hook slightly pressed to one of the poles of this electromagnet box 46 (Fig. 3) and a ratchet wheel 47 mounted on an axis, on which, in addition, a disk 50 with a sleeve and twenty Finger holes is mounted. The electromagnet 45 is provided with two windings that can be switched from differential to para-day. On the wheel 47 there is a spring contact 48 and a winding spring 49, and on the sleeve near the wheel 47 there is a contact with a spring 511, which is pressed against contact 48; when the disk 50 rotates at one of the holes, these contacts open; at the rear side of the disk, near the last finger hole, there is a tide with an inclined bar 52, against which a spring contact 53 with two mutually perpendicular plates is placed; on contact of tide 52 with contact 53, one of the plates bends to the side, and the inclined bar passes under the second plate and bends it upwards; during the reverse movement of the protrusion, the inclined plank passes over the second plate and bends it downwards; spring contact 54 is located against the second plate; on the back side of the disk 50 there is a step switch 56, which switches the contact 57, and thus the windings of the electromagnet 45, in the first step, in series, in the second, in parallel, in the third, again in series, etc., and consists of a gear driven in motion by a mating bracket 55 attached to the back side of the disk in such a way that it engages the wheel 47 and takes it one step only when the disk 50 rotates in one direction. The very switching of the contacts 57 is made by switching the switch; Next to contact 53, there is a three-plate contact 58, the middle plate of which is connected to the bell, extreme to the ground, and a third, closer to the contact 53, j with the return wire of the telephone; Against a small angle, a stop bracket 59 is located against the first and last finger hole, which holds the finger during rotation of the disk 50 and simultaneously switch the middle plate of the contact 58 from the ground contact to the contact of the second wire; The return of said stop bracket is made by lever 60, on which the telephone hangs.

If the subscriber inserts a finger into the hole of the disk 50 with the number of the required group, turns the disk up to the stop of the finger in the bracket 59 and releases the disk, then at the first moment of movement of the disk 50 (Fig. 3 and 4) the contacts 48 and 51 will open, then short The contacts 53, finally, the installation of the switch 56 by the spring clip 55 at the contacts 57, which include a winding of a large resistance of the romagnet 45,; but with a small number of active turns; when you put your finger in the bracket 59

the contacts 58 of the subscriber’s bell will switch from the ground contact to the second (return) wire, and when the disk 50 is released, the contacts 48 and 51 will close, resulting in a closed circuit and the electric motor 32, handle 31 and washer on the motor 32 shaft which, when rotated, will switch contact 40 from one pole of battery I to another. Due to this, alternating current pulses will be sent to the subscriber, from which the electrically-activated electromagnet 45 will move, influencing, in turn, measles 46; the latter will make it possible to turn around the wheel 47 and, after a series of repeated pulses (selection), disk i) 0 with a tide 52 will open the contacts b3; The outer circuit is interrupted, and the disk 50, by its further inertia one-step travel, closes contact 53 with contact 54 with pin 54 and forms for a short time a new reverse circuit through which the subscriber will be connected to the required group of the called station. After that, the secondary rotation of the disk 50 by the same loot (that is, by inserting a finger into the hole corresponding to its desired phone number) until it stops with a finger in the bracket 59 is the same; I release this disc at the first moment (Fig. 3 and 4) the contacts 48 and 51 will open, then the contacts 53 will close, and finally the spring switch 56 will be installed w, with the clip 55 to the position in which the contacts 57 switch on the parallel winding of the electromagnet 45 with low resistance but with a large number of active turns; The release of the disk 50 when the finger is pressed into the bracket 59. The contacts 48 and 51 will close, a circuit is formed: (Fig. 4) contacts 48 and 51. Contact 53, the subscriber's direct wire (Fig. 1), contacts 19 and 22 , relay 12 winding, contacts 11, relay winding 331, resistance 41, contacts 40 and 411, battery I, from the middle of the battery in the return wire to the polarized electromagnet 45, through the switching contacts 57 to contact 48. The relay 33 will come into effect and there is no left shoulder of the balancer box 33. The following circuits form: contacts 33 and 33, electromagnetic clutch, interlock E roll 20, battery I with return wire to contacts 33 and ЗЗЗ. The motor 32 will drive the handles 311, etc. (312 is shown in the drawing), the linear finders 301 and 302, etc., and the washer mounted on the shaft of the electric motor 32, with help 1 and which will be sent to the electromagnet 45 selection (variable) pulses of a weaker current than in the first case due to the included resistance 415; The electromagnet 45 will act in the same way as when it was first turned on, and the measles 46 will gradually release the wheel 47.

After a series of repeated parcels of selection pulses, the disk 50 at the end of the stroke with a tide 52 will open the contacts 53 and break, as in the first slz-cha, the external circuit; upon its further movement, the tide bar 52 also closes contacts 53 and 54 and for a short time forms a new reverse circuit: (Fig. 1) ground 3, contacts 54 and 53 (not shown), subscriber forward wire, contacts 19 and 22 ( not shown), relay winding 12, contacts 11, demagnetizing ZZ winding, battery II, contacts 28 and 283, contacts 59 and ground, demagnetizing under the influence of this current. the winding 33 will demagnetize the relay 33 and the balancing measles 33, made in the form of a yoke, will come to rest. The action of the winding 13 of the electromagnet, including; its electromagnet 1, is balanced by the action of the winding 12, through which in this case the reverse current will flow: the second pin 14 (.fig. 2) does not have, at the end of the projection, moves away from the electromagnet and closes contacts 14, forming a circuit: (fig, 1) battery I, contacts 14, electromagnet winding 1, contact 22 (in fig.5, winding relay 12, contacts 11, relay 28, contacts and the other pole of battery I. Electromagnet 1 will push rod 2 the plug 6 to the pin of the contact row 25; the plug is held in this position the magnet 7, and the head 5 closes the tires a and 6. forming a circuit: bahar I, bus b, goal; lamb 5, bus a, winding 35, handle 31, contact of group finder 30, handle 312, required contact of linear finder 30 , an electromagnet 1 of the required telephone, a winding of the relay 12, contacts 11, a relay 28. A contact of the battery and the other pole of the battery I, which causes the electromagnet 1 of the required subscriber to push the plug 6 to one of the contacts p 25. 25. Under the influence of the winding 35i with the assistance of the winding 36 will occur the attraction of the core and the switching of ectrodvit-atel to reverse. Due to the fact that electromagnet1 1 and 1 push plug 6 and 6, pins 11 and 11 open and the circuit is open, and through electromagnets J and 1, winding 35 and finder handles, as well as contacts 14, a new circuit is interrupted ( Fig. 5): ground 3, machine inductor 69, pins 286 and 28, closed by turnips 28, choke coil, caller return wire, pin 58z, 58, phone ring, caller straight wire, pin 19, load cord 10 plug 6, pin 25, pini, second pin 25, pin 6 of the desired phone, contacts 19, direct wire to binding subscriber, you call the desired party, the contact 581 and 58 and the land 84. The inductor signals give to know what the connection is ready. At the same time, the battery I is sent via buzzer 70 (Fig. 2) by brush 441, ring 44, contacts 25, the direct wires of the subscriber, call or telephone of the caller, return wires, middle of battery 1, intermittent currents, which and will be heard by the caller, provided that the required subscriber is busy. Under the action of the relay 28, the electromagnetic coupling 61 will be closed by contacts 28 and 28. sitting on the wapa of the motor 26 (Fig. 2 and 5), which causes the clutch to start moving 27 (FIG. 2), and with it the shaft 23 with the tape 24 will move one step. This is facilitated by a typical wheel, which in turn rotates off the coupling 61 from the circuit. If, after lifting the tape, the required subscriber does not pick up the tube, the machine inductor will be opened by contact 28 from contact 28, to which the return wires are connected, and closed with one of contacts 28. connected in seconds, the transformer 43i with contact 44 and further along the straight wires to the subscribers to whom the inductor call will be sent at intervals. When the caller removes the tube with the spring of the lever 60, the stop bracket 59 will return to its place and switch the call of the designated subscriber from the return wire to the ground. Disconnection of subscribers occurs by a double way. 1) The subscriber hangs up the tube, a reverse circuit is formed (partially

FIG. 1): ground 3, pin 54, straight wire, pin 19, top pair of pins 11 (bottom open), battery II, pins 28 and 28z, and ground S. .., resulting in a winding of relay 12 having reverse current, demagnetized relay 12; two cores, without the protrusion 6 already underneath (in FIG. 5), by opening the circuit of relay 12 and electromagnet 7, and plug 6 will return to its original position.

2) Subscribers talk more than the set time. The shaft 15, and with it the washers 16 rotate at a predetermined speed and before a certain time is arranged so that the circuit of the electromagnet 7 and (winding) relay 12 is open, all of which plug 6 will move away from contact 25.
