  Vorrichtung zur Regelung der Lautstärke an Harmonien u. dgl.

 die Stimmstöcke angeschlossen. Die Tourenzahl des Ventilators ist durch dem Elektromotor   vorge-   schaltet Widerstände regulierbar. Ein kleinerer Widerstand wird die Tourenzahl erhöhen und dadurch   ein Anwachsen des Druckes oder Soges bewirken, während ein grösserer Widerstand die entgegengesetzte Wirkung ausüben wird. Folglich wird beim Spiel die Verkleinerung des Widerstandes eine Verstärkung,   die Vergrösserung des Widerstandes aber eine   Abschwächung   des Tones ergeben. Die Veränderung der
Grösse des Widerstandes kann beispielsweise mittels eines sogenannten Schiebewiderstandes, welcher in der Leitung   zum"Motor eingeschaltet   ist, bewirkt werden.

   Auf der beiliegenden Zeichnung ist eine 
 EMI1.2 
 Ausströmkanal jeder Zunge direkt   abschliesst.   B ist der Stimmstock mit dem daraufliegenden Zungen.   C   ist ein Ventilator, welcher durch den Motor D mittels gleicher Welle angetrieben wird. Der Motor D erhält durch die Leitungen Gl und   6'i2 elektrischen Strom.   In G2 ist ein Widerstand E, welcher durch die bewegliche Schleiffeder F vergrössert oder verkleinert werden kann, eingeschaltet. 



   Ist der Motor D eingeschaltet, so wird durch den damit verbundenen Ventilator C Pressluft in den Stimmstock B befördert, deren Druckhöhe von der Umlaufzahl des Motors, bzw. Ventilators abhängig ist. Wird nun mittels der schleifende Feder F der Widerstand E vergrössert oder verkleinert, so wird der Motor bzw. der Ventilator langsamer oder schneller laufen, damit der Druck in B sich vermindern bzw. erhöhen, d. h. die Lautstärke des Harmoniums wird sich abschwächen oder verstärken.

 EMI1.1
 the reed blocks connected. The number of revolutions of the fan can be regulated by the electric motor connected upstream with resistors. A smaller resistance will increase the number of revolutions and thereby cause an increase in pressure or suction, while a larger resistance will have the opposite effect. Consequently, when playing, the decrease in the resistance results in a gain, while the increase in the resistance results in a weakening of the tone. The change in
The magnitude of the resistance can be brought about, for example, by means of a so-called slide resistance, which is switched on in the line to the motor.

   On the accompanying drawing is a
 EMI1.2
 Directly closes off the outflow channel of each tongue. B is the sound post with the reed on it. C is a fan which is driven by the motor D by means of the same shaft. The motor D receives electrical current through the lines Gl and 6'i2. A resistor E, which can be increased or decreased by the movable slide spring F, is switched on in G2.



   If the motor D is switched on, compressed air is conveyed into the sound post B by the fan C connected to it, the pressure level of which depends on the number of revolutions of the motor or fan. If the resistance E is now increased or decreased by means of the sliding spring F, the motor or the fan will run slower or faster so that the pressure in B decreases or increases, ie. H. the volume of the harmonium will decrease or increase.
