Zusatz zum Patent 276887.Addendum to patent 276887.

Patentiert im Deutschen Reiche vom 4. Dezember 1913 ab. Längste Dauer: !.Februar 1928.Patented in the German Empire on December 4, 1913. Longest duration:! February 1928.

Im Hauptpatent 276887 ist ein Nummernschalter für selbsttätig betriebene Fernsprechanlagen beschrieben, bei dem die Einstellvorrichtung derart ausgebildet ist, daß vor den der Einstellung und Wahl der gewünschten Teilnehmernummer entsprechenden Bewegungen der Einstellteile sowohl beim Aufzug als auch Ablauf ein toter Weg liegt, während dessen Zurücklegung die Stromstoßsendung ruht, zum Zweck, bis zur Abgabe des ersten Stromstoßes selbst verhältnismäßig langsamen Schaltwerken genügend Zeit zu ihrer Einstellung zu lassen.In the main patent 276887 is a number switch for automatically operated telephone systems described, in which the adjusting device is designed such that before the movements corresponding to the setting and selection of the desired subscriber number of the adjustment parts lies a dead path in both the elevator and the process, while the completion of which the impulse transmission is suspended, for the purpose of delivering the first Current surge even relatively slow switchgear has enough time to adjust allow.

Nach vorliegender Erfindung wird dasselbe Resultat erzielt, trotzdem die Impulskontaktunterbrechungen vom Beginn des Rücklaufes der Nummernscheibe an erfolgen, und um dieses zu erreichen, wird erfindungsgemäß die Wirkung einer bestimmten Anzahl von StromimpulsenAccording to the present invention, the same result is achieved, despite the pulse contact interruptions take place from the beginning of the return of the dial, and in order to achieve this, according to the invention, the effect a certain number of current pulses

durch Überbrückung der. Impulskontakte aufgehoben. Zu diesem Zweck ist ein weiterer Kontakt vorgesehen, der z. B. beim Aufzug der Nummernscheibe durch die achsiale Verschiebung eines Zahnrades parallel zu den Impulskontakten geschaltet wird. Beim Ablauf der Nummernscheibe wird das Rad dann gedreht und kehrt in seine ursprüngliche Lage zurück, wodurch der Parallelkontakt wieder ausgeschaltet wird und die darauffolgenden Stromimpulse durch die Leitung gehen.by bridging the. Impulse contacts canceled. To that end is another Contact provided, the z. B. when the dial is lifted by the axial displacement of a gear is switched in parallel to the pulse contacts. When the dial expires, the wheel will then rotated and returns to its original position, whereby the parallel contact again is switched off and the subsequent current pulses go through the line.

Auf der Zeichnung ist ein entsprechend der Erfindung ausgebildeter Nummernschalter in Fig. ι in Vorder- und in Fig. 2 in Rückansicht dargestellt, wobei die verschiedenen Teile sich in ihrer Ruhelage befinden. Fig. 3 zeigt das Zahnradwerk für die Bewegung des Parallelkontaktes.The drawing shows a number switch designed according to the invention in Fig. ι shown in front and in Fig. 2 in rear view, the various Parts are in their rest position. Fig. 3 shows the gear train for moving the Parallel contact.

Auf der durch die Platte 1 geführten Welle 2 ist die mit den üblichen zehn Fingeröffnungen versehene Nummernscheibe 3, das Anschlagrad 4 und ein Mitnehmerarm 5 befestigt. Eine auf der Welle 2 lose sitzende Scheibe 6 steht unter der Einwirkung einer Feder 7, die bestrebt ist, die Scheibe um einen durch einen Anschlag begrenzten Abstand a, b zu drehen, hieran aber durch einen Anschlag 8 an dem Anschlagrad 4 verhindert wird. Auf der Welle 2 sitzt des weiteren ein Schneckenrad 9, das mit einer auf der Bremswelle 11 einer Schnekkentriebbremse sitzenden Schnecke 10 in Eingriff steht. Die Bremse dient zur Regelung des Rücklaufes der Nummernscheibe, die in bekannter. Weise durch aufgespeicherte Federkraft in die Ruhelage zurückgeführt wird.On the shaft 2 guided through the plate 1, the dial 3, which is provided with the usual ten finger openings, the stop wheel 4 and a driver arm 5 are fastened. A disc 6 sitting loosely on the shaft 2 is under the action of a spring 7 which tries to rotate the disc by a distance a, b limited by a stop, but this is prevented by a stop 8 on the stop wheel 4. A worm wheel 9, which is in engagement with a worm 10 seated on the brake shaft 11 of a worm drive brake, is also seated on the shaft 2. The brake is used to regulate the return of the dial, which is known in. Way is returned to the rest position by stored spring force.

Auf der Bremswelle 11 sitzt ein Mitnehmerrad 12 und ein Unterbrecherrad 13. An der Platte ι ist ein Bügel 14 befestigt, der bei 15 geschlitzt ist. In diesen Schlitz greift ein an einer gezahnten Scheibe 16 angebrachter kegelförmiger Zapfen 17. Außerdem sitzt an der Scheibe 16 ein Anschlag 18. Die Scheibe 16 ist an einer Büchse 19 angebracht, die durch einen federnden Kontakt 20 nach aufwärts gegen den Bügel 14 angedrückt wird undA driver wheel is seated on the brake shaft 11 12 and a breaker wheel 13. A bracket 14 is attached to the plate ι, which at 15 is slotted. A conical one attached to a toothed disk 16 engages in this slot Pin 17. In addition, a stop 18 is seated on the disk 16. The disk 16 is attached to a sleeve 19, which by a resilient contact 20 upwards is pressed against the bracket 14 and

is isolated from the contact. The interrupt wheel 13 is used to open the pulse contact 21. A locking hook 22 holds the stop wheel 4 in its rest position, and a stop 23 on the disc 6 is used to keep a contact 24 open when the Number switch is in the rest position. Another stop 25 on this The purpose of the disk is to hold the brake in its rest position.

The mode of operation of the number switch when commissioning is carried out by a participant as follows:

When the receiver is picked up, the finger washer 3 connected to the stop washer 4 is released by releasing the locking hook 22. Then the participant starts from a finger opening, e.g. B. from No. 6 to rotate the disc in the usual way up to a stop 26, whereby the stop disc 4 is rotated and the disc 6 releases so that it is rotated by the spring 7 by the distance a, b and this by means of the stop 23 provided on it, the switching of the contact set 24 is effected, and the stop 25 triggers the locking of the braking element. The driver 5 fastened on the shaft 2 comes into engagement with the stop 18 on the toothed disk 16 through a projection 27 and rotates the disk, the pin 17 being pushed out of the slot 15 in the bracket 14 onto the surface of the bracket. This results in the downward movement of the disc 16 and the closure of the contact 20. The disk 16 also comes to lie at the same height as the driver wheel 12 as a result of this displacement.

As soon as the participant releases the number disc, it begins under the Influence of the spring force stored during pulling up to return to their rest position and takes the worm wheel 9 connected to it by a locking spring, which is attached to a Rotation in the opposite direction when the dial is wound by a spring 28 is prevented. The rotation of the worm wheel 9 causes the brake shaft and the Driving wheel 12, which sets the toothed disc 16 in rotation. At the beginning of the rewind on the dial, there are already pulse contact interruptions due to the intervention of the tone wheel 13 with the contacts 21, which when passing each individual tooth the disc 13 are separated from each other. However, these contact breaks have no effect because contact 20 is closed. However, if the toothed disc 16 is so been turned far that the pin 17 comes back to lie in the slot 15 in the bracket 14, then it is pushed upwards by the resilient contact 20, and the contact opens so that the current pulses now get into the line.

. During the return movement, the driver arm 5 no longer rotates the disk 16 because the shoulder 27 is provided resiliently and in this direction of rotation when passing the pin gives way.

Since it now depends on the absolute length of the pause, one can suppress the Impulse contacts also have an effect on the end or another point of the disc movement embarrassed. '.;. ■ ·>
