   Soll nun der Draht plötzlich stillgesetzt werden, weil das Gespräch unterbrochen wird, so wird   zunächst einmal   der Strom zum Motor ausgeschaltet, gleichzeitig wird auch der zur Achse al 
 EMI2.1 
 die Scheibe   fl,   so dass die gegenseitig wirkenden Drehmomente sich nahezu aufheben und, somit die Scheibe f1 und der damit verbundene Spulenträger b1 stillgesetzt wird. Um zu verhindern, dass bei Überwiegen des Drehmomentes der herabgesenkten Masse ein Mitnehmen in der nunmehr entgegengesetzten Richtung eintritt, ist die sperrvorrichtung m, l vorgesehen. Die Klinken m wurden in diesem Falle in das Sperrad l einfallen und die Einrichtung somit stillgesetzt werden. 



   Will man den Apparat   rückwÅart8lalúen   lassen, um ihn z. B. zur Wiedergabe eines aufgenommenen Gespräches bereitzustellen, so muss beim Schliessen des Stromkreises für den Motor der zur der Achse a2 gehörige   Elektromagnet V2 erregt werden,   so dass nunmehr   c   die angetriebene Spule ist, auf die sich der Draht aufwickelt. Beim Stillsetzen wird gleichzeitig wieder der dazu- 
 EMI2.2 
 angehalten. Während des normalen Laufes des Motors kann der Regulierungswiderstand r benutzt werden, weil durch die Zentrifugalkraft die Klinken o sich von dem Kontakt n entfernen und der Kurzschluss dadurch unterbrochen wird. 



   PATENT-ANSPRÜCHE :
1. Maschine zum Auf- und Abwickln des Stahldrahtes für magnetische Phonogramme von 
 EMI2.3 
   gesetzten Umlaufsinnes   beider Wellen gebremst wird.

   If the wire is suddenly to be stopped because the conversation is interrupted, the current to the motor is first switched off, and at the same time that to the axis al
 EMI2.1
 the disk fl, so that the mutually acting torques almost cancel each other and thus the disk f1 and the coil carrier b1 connected to it are stopped. In order to prevent that when the torque of the lowered mass predominates, it is carried along in the now opposite direction, the locking device m, l is provided. In this case, the pawls m would fall into the ratchet wheel l and the device would thus be stopped.



   If you want to reverse the device, e.g. B. to play back a recorded conversation, the electromagnet V2 belonging to the axis a2 must be excited when the circuit for the motor is closed, so that now c is the driven coil on which the wire is wound. When the machine is stopped, the
 EMI2.2
 stopped. The regulating resistor r can be used during normal running of the motor because the centrifugal force causes the pawls o to move away from the contact n and the short circuit is thereby interrupted.
