  Vorrichtung zum Verhindern des Einfrierens von mit Zungenstimmen und Ventilen ausgestatteten   Signal-oder Musikinstrumenten.   



   Bei Blasinstrumenten mit Stimmen, insbesondere bei Signalhörnern, kommt es vor, dass schon bei verhältnismässig geringer Kälte ein Einfrieren der Stimmen und Ventile eintritt. Dieses Einfrieren kann schwerwiegende Folgen haben, wenn z.   B.   das Signalhorn zur Warnung der Arbeiter einer Streckenkolonne bei der Eisenbahn verwendet wird. Man könnte daran denken, das Signalhorn in den Zwischenpausen mit einem Wärmeschutz zu versehen, es also z.   B.   unter dem Mantel zu tragen. Das ergibt aber den Nachteil, dass das Horn bei drohender Gefahr nicht griffbereit ist und dass das Warnsignal nicht rechtzeitig abgegeben werden kann. 



   Durch die Erfindung wird ein anderer Weg beschritten. Das Signalhorn nach der Erfindung ist mit einem vor den Ventilen liegenden Filter ausgestattet, das den beim Hindurchblasen in das Horn eintretenden Wasserdampf aufnimmt. Als Füllmaterial für das Filter eignen sich nicht   zerfliessliehe   Trockenmittel, insbesondere das Silikagel. Das Filter kann fest mit dem Signalhorn verbunden sein, besser ist es jedoch, wenn eine   Auswechselungsmöglichkeit   besteht. 



   Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Es ist darin a das Signalhorn, b der Teil des Signalhorns, der die Stimme und die Ventile enthält, c ist das Mundstück und   d   das zwischen Mundstück und Horn eingeschaltete wasserabsorbierende Filter. Mundstück und Horn sind mit dem Filter durch die Gewinde e und t verbunden. 



   Die Erfindung ist nicht auf Signalhörner beschränkt, sondern kann auch bei Musikinstrumenten mit Zungenstimmen, also z. B. Schalmeien, Verwendung finden. 



   PATENT-ANSPRÜCHE :
1. Vorrichtung zur Verhinderung des Einfrierens von mit Zungenstimmen und Ventilen ausgestatteten Signal-oder Musikinstrumenten, dadurch gekennzeichnet, dass zwischen dem Mundstück und dem frostgefährdeten Teil des Instrumentes ein wasserabsorbierendes Filter mit nicht   zerfliesslichem   Filtermaterial eingeschaltet ist.

  Device for preventing the freezing of signal or musical instruments equipped with reed voices and valves.



   In wind instruments with voices, especially horns, it happens that the voices and valves freeze even when it is relatively cold. This freezing can have serious consequences if e.g. B. the horn is used to warn the workers of a line column on the railway. One could think of providing the signal horn with heat protection in the breaks. B. to wear under the coat. However, this has the disadvantage that the horn is not ready to hand when danger is imminent and that the warning signal cannot be given in time.



   The invention takes a different approach. The horn according to the invention is equipped with a filter located in front of the valves which absorbs the water vapor entering the horn when it is blown through. Non-deliquescent desiccants, particularly silica gel, are suitable as filling material for the filter. The filter can be permanently connected to the horn, but it is better if it can be replaced.



   The drawing shows an embodiment of the invention. In it, a is the signal horn, b the part of the signal horn that contains the voice and the valves, c is the mouthpiece and d the water-absorbing filter inserted between the mouthpiece and the horn. The mouthpiece and horn are connected to the filter by threads e and t.



   The invention is not limited to signal horns, but can also be used in musical instruments with reed voices, so z. B. Shawms, find use.



   PATENT CLAIMS:
1. Device for preventing the freezing of signal or musical instruments equipped with reeds and valves, characterized in that a water-absorbing filter with non-deliquescent filter material is connected between the mouthpiece and the frost-prone part of the instrument.
