Description

  

   <Desc/Clms Page number 1> 
 



  Elektromagnetische Hupe mit zwei Schallplatten. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

   naturlich auch dem Anschlag & zugeteilt   werden, wobei dann die Platte 6 kein   besonderes nsehlagstitek   zu tragen braucht. 



   Um die durch den Antrieb ermöglichte grosse Geschwindigkeit auch voll   ausnützen zu können,   
 EMI2.1 
 die angestossene Schallplatte 6 zwischen der Schallplatte   J   und dem Elektromagneten 7 liegt. Der   Bolzen- ?   ist dann mit einem entsprechenden, z. B. bundartigen. Anschlag für die Schallplatte 6 zu versehen. Dies hat den Vorteil, dass die kurzwelligen Töne der angestossenen Platte beim Durchtreten durch Öffnungen der gesteuerten Platte weniger gedämpft werden. 



   PATENT-ANSPRÜCHE :
1. Elektromagnetische Hupe mit zwei Schallplatten. von denen die eine von dem   elektromagne-   tischen Antrieb unmittelbar   beeinflusst wird,   während die andere von der unmittelbar angetriebenen Platte aus angestossen und dadurch in Schwingungen versetzt wird. dadurch gekennzeichnet, dass der elektromagnetische Antrieb der einen Schallplatte unabhängig von der Bewegung   der angestossenen   Schallplatte gesteuert wird.

   can of course also be assigned to the stop &, in which case the plate 6 does not need to carry any special nsehlagstitek.



   In order to be able to fully utilize the high speed made possible by the drive,
 EMI2.1
 the struck record 6 lies between the record J and the electromagnet 7. The bolt- ? is then with a corresponding, z. B. fret-like. Stop for the record 6 to be provided. This has the advantage that the short-wave tones of the struck plate are less attenuated when passing through openings in the controlled plate.



   PATENT CLAIMS:
1. Electromagnetic horn with two records. one of which is directly influenced by the electromagnetic drive, while the other is impacted by the directly driven plate and is thus set into vibrations. characterized in that the electromagnetic drive of the one record is controlled independently of the movement of the record that has been struck.

Claims (1)

2. Hupe nach Anspruch 1, dadurch gekennzeichnet, dass zur Erzielung einer hohen Schwingungszahl der gesteuerten Schallplatte sowohl der Kern als auch der Anker des Elektromagneten aus geblättertem Eisen bestehen. 2. Horn according to claim 1, characterized in that both the core and the armature of the electromagnet are made of peeled iron to achieve a high number of vibrations of the controlled record. 3. Hupe nach Anspruch l, dadurch gekennzeichnet, dass zur Erzielung einer möglichst grossen Amplitude bei hoher Eigenschwingungszahl vorzugsweise die gesteuerte Schallplatte aus dünnem Material EMI2.2 den Oberton liefert, dadurch gekennzeichnet, dass die angestossene Schallplatte zwischen der gesteuerten Schallplatte, die in bekannter Weise mit Öffnungen versehen ist und dem elektromagnetischen Antrieb angeordnet ist. EMI2.3 3. Horn according to claim l, characterized in that in order to achieve the largest possible amplitude with a high natural frequency, preferably the controlled record made of thin material EMI2.2 delivers the overtone, characterized in that the struck record is arranged between the controlled record, which is provided with openings in a known manner, and the electromagnetic drive.
