  Schauzeichen für Fernsprech-und Summerströme. 



   Die vorliegende Erfindung betritt ein Schauzeichen, das durch Wechs31strom oder unterbrochenen Gleichstrom betätigt wird. Als besonderes Merkmal weist es einen Umlaufkörper auf, der in einem oder zwei einzelnen Punkten an einer Stütze hängt, die ihn durch eine im wesentlichen in der Umlaufebene des Körpers erfolgende, elektromagnetisch veranlasste Rüttelbewegung in Umdrehung setzt. Die Bewegung der Stütze durch den Elektromagneten kann entweder unmittelbar oder aber   mittelbar,   z. B. in der Weise erfolgen, dass die   Bewegun einmr   Fernhörermembran auf die Stütze   übertragen   wird, wodurch dann die Fernsprech-bzw. Ruf-

 leicht federnd angedrückt wird. Sie könnte aber auch fest mit der Membran verbunden werden. 



  Das eine Ende a der Feder ist in einer Hülse h befestigt, weiche in der Schallöffnung des Fernhörers durch Federn leicht abnehmbar festgehalten wird. Die besondere Form der Stütze ist aus Fig. 2 ersichtlich. Der   Umlaufkörper   g besteht aus einer Scheibe aus leichtem Material, z. B. Zelluloid, deren Rand umgebördelt ist, so dass die Spitze f des Drahtbügels in den so gebildeten Innenrand hineingreift und die Scheibe auf dieser Spitze ruht.

   Die Vorderseite der 
 EMI1.3 
   gepresst wird, macht   der Bügel die Schwingungen der Membran mit, und zwar schwingt dieser Teil c im wesentlichen   vor-und rückwärts um den Befestigungspunkt a der Drahtstütze.   Infolge der starken Federung des Teiles d der Stütze erhält dabei der   Stützpunkt f eine   im   wesent-   lichen parallel zur   Membran   verlaufende, seitliche   Rüttplbewegang und wirft   den Umlaufkörper, da derselbe leicht, ist, nach der Seite und teilweise in die Höhe. Der Umlaufkörper g wird beim Zurückfallen immer wieder an einem andern Punkt seines inneren Umfangs durch die   Spitze/

  Indicator for telephone and buzzer currents.



   The present invention enters a flag operated by alternating current or intermittent direct current. As a special feature, it has a revolving body that hangs in one or two individual points on a support which sets it in rotation by an electromagnetically induced vibrating movement essentially in the plane of rotation of the body. The movement of the support by the electromagnet can either directly or indirectly, e.g. B. be done in such a way that the movement einmr remote receiver membrane is transferred to the support, which then the telephone or.

 is pressed slightly resiliently. But it could also be firmly connected to the membrane.



  One end a of the spring is fastened in a sleeve h, which is held easily removable in the sound opening of the telephone receiver by springs. The special shape of the support can be seen from FIG. The recirculating body g consists of a disc made of lightweight material, for. B. Celluloid, the edge of which is flanged so that the tip f of the wire bracket engages in the inner edge thus formed and the disc rests on this tip.

   The front of the

   is pressed, the bracket makes the vibrations of the membrane, and this part c swings essentially back and forth around the attachment point a of the wire support. As a result of the strong resilience of part d of the support, the support point f receives a lateral vibrating motion that runs essentially parallel to the membrane and throws the circulating body, since it is light, to the side and partially upwards. The recirculating body g is repeatedly pushed back at another point on its inner circumference by the tip /
