Nummernschalter für selbsttätige Fernsprechanlagen.
Gegenstand der Erfindung bildet eine neue, einfache Ausführungsform für Nummernschalter, bei welchen gemäss dem Patente Nr. 68977 die Einstellvorrichtung derart ausgebildet ist, dass vor den der Einstellung und Wahl der gewinschten Teilnehmernummer entsprechenden Bewegungen der Einstellteile sowohl beim Aufzug als auch beim Ablauf eine Leerlaufstrecke vorgesehen ist.
Die Erfindung besteht darin, dass zum Erzeugen der Leerlaufstrecke am Nummernschaltcr zwischen der Nummernscheibe und dem Kontaktwerk mehrere, miteinander durch Mitnehmer
EMI1.1
Summe der Leerlaufstrecken bestujunt, welcho die einzelnen Kupplungsglieder bei ihrer Bewegung zurückzulegenhaben..
Eine besonders einfache und gedrängte Anordnung der Kupplungsglieder wird erreicht, wenn diese gemäss der Frfindung als auf einer gemeinsamen Welle drehbar angeordnete Mit- nehmprscheiben ausgebildet sind. Hiebet können zweckmässig die Kupplungsglieder durch entsprechende Stellung ihrer Mitnehmer noch derart ausgebildet werden, dass die aus denselben zusammengesetzte Kette für jeden Leerlaufschritt der Nummernscheibe einen vollen Umlauf

Number switch for automatic telephone systems.
The subject of the invention is a new, simple embodiment for number switches, in which, according to patent no. 68977, the setting device is designed in such a way that an idle distance is provided before the movements of the setting parts corresponding to the setting and selection of the desired subscriber number, both in the elevator and in the process is.
The invention consists in that, in order to generate the idle section on the number switch between the number disc and the contact mechanism, several, with one another by means of drivers
EMI1.1
Sum of the idle distances determined what the individual coupling links have to cover when moving.
A particularly simple and compact arrangement of the coupling members is achieved if, according to the invention, they are designed as driving disks rotatably arranged on a common shaft. The coupling links can expediently be designed by appropriately positioning their drivers in such a way that the chain, which is composed of the same, makes one full revolution for each idling step of the dial
