  Wird dagegen der Anker durch Erregung des Elektromagneten nach dem Pole 90 bewegt, so bleibt der Arm 79 des Hebels 72 in seiner für gewöhnlich angenommenen Stellung stehen, und die Klinke wird bei Drehung des Hebels 51 ausgerückt und lässt das Zählwerk unbeeinflusst. Mit der Bewegung des Ankers ist die Scheibe 81 auch entsprechend verstellt worden, so dass der Teilnehmer imstande war, an der   SchauöNnung J   zu beobachten, ob der   Zählvorgang   ordnungsgemäss stattgefunden hat. 



   Es sei noch erwähnt, dass die Form der Scheibe beliebig gewählt werden kann. und dass z. B. statt der dreieckigen eine mehreckige Scheibe verwendet werden kann, wobei natürlich eine entsprechende Anzahl der Anschläge 64 und 65 vorhanden sein muss. Eine mehr als dreieckige Form der Scheibe hätte den Vorzug, dass der Hub des Schaftes 60 herabgemindert würde. 



   PATENT-ANSPRÜCHE :
1. Gesprächszähler für Fernsprechstellen, bei welchem nach Drücken einer Taste ein Kontakt geschlossen und nach Stöpseln der Klinkenbuchse auf dem Amte ein Magnet des Zählers erregt wird, dadurch gekennzeichnet, dass durch   Drücken   der Taste (18, 61) eine Feder   (2?, 58)   eines Schaltwerkes gespannt wird, worauf nach Erregung des   Magneten   die Feder entspannt.

  If, on the other hand, the armature is moved to the pole 90 by energizing the electromagnet, the arm 79 of the lever 72 remains in its normally assumed position, and the pawl is disengaged when the lever 51 is rotated, leaving the counter unaffected. With the movement of the armature, the disc 81 was also adjusted accordingly, so that the participant was able to observe at the viewing opening J whether the counting process had taken place properly.



   It should also be mentioned that the shape of the disk can be chosen as desired. and that z. B. instead of the triangular one a polygonal disc can be used, of course a corresponding number of stops 64 and 65 must be present. A more than triangular shape of the disk would have the advantage that the stroke of the shaft 60 would be reduced.



   PATENT CLAIMS:
1. Call counter for telephone stations, in which a contact is closed after pressing a button and after plugging the jack socket at the office, a magnet of the counter is excited, characterized in that a spring (2 ?, 58) is activated by pressing the button (18, 61) ) a switching mechanism is tensioned, whereupon the spring is relaxed after the magnet is excited.
 EMI5.1
 work done by the spring.

Claims

2. Call counter according to claim 1, characterized in that the pendulum-mounted armature (9) of the polarized magnet formed in a known manner has an arm (39) which engages between cooperating resilient contact arms (25, 31), one of which (25) each can be brought into engagement according to the direction of the swing of the armature arm with the counter disks in a known manner, after the connection of the contact arms has previously been effected by pressing the button.

3. Call counter according to claim l and 2. characterized in that the one contact arm (25) is rotatably attached to a resiliently oscillating lever arm (22) and is articulated to an angle piece (24), one leg of which is connected to the shaft of the spring action Button (18) cooperates and when the button is depressed by means of a resilient EMI5.2 can be brought into engagement with the transport wheel (37) of the counter.

5. Call counter according to claim 1 to 4, characterized in that an insulating piece (35) is rotatably attached to the ratchet tooth (32) of one contact arm (31). that after EMI5.3 EMI5.4 slides, influenced in such a way that when the key is depressed, the disc is rotated into a position in which it closes a contact (67) of a circuit leading through the office and including the windings of the polarized magnet (1, 2) and in this position through EMI5.5 <Desc / Clms Page number 6> piece (68) interact and are influenced in such a way that they prevent the disc from further rotation in the first working position, while the release prepares for further rotation when tightening the armature and in the subsequent,

by moving back the armature caused further rotation into the rest position the contact (67) is opened again.

9. conversation counter according to claim 1, 7 and 8, characterized in that the pendulum-mounted armature (48) by two one-armed, spring-action levers (71, 72) which are mounted with the armature on a common pin (50), in Central position is held and one lever (72) has an extension (79) beyond its pivot point, which prevents the pawl (3) from engaging in the Fortachaltrad (54) of the counter disks when the armature moves.
