KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Erfindung bezieht sich auf eine Verbesserung der nach Patent 278668 geschützten Apparate zur Aufnahme und Wiedergabe von Tönen.The invention relates to an improvement on that protected by patent 278668 Apparatus for recording and reproducing sounds. Nach dem Hauptpatent sollen dabei die Schallwege des Apparates oder Teile derselben aus Blei hergestellt oder die Wände der Schallwege oder ein Teil derselben mit einem Belag aus Blei versehen werden. Wenn nun auch feststeht, daß diese Apparate in der Wiedergabe und Aufnahme von Tönen auf einer hohen Stufe der Vollendung stehen, so hat sich doch ergeben, daß die Wiedergabe von Tönen, welche von anderen, nicht nach dem Hauptpatent hergestellten Apparaten aufgenommen wurden, noch verbesserungsfähig ist, indem durch Herstellung eines Teiles der Schalleitung aus Leder der den mit fremden Apparaten aufgenommenen Tönen bei der Wiedergabe anhaftende metallische Beiklang genommen wird.According to the main patent, the sound paths of the device or parts of the same should be used made of lead or the walls of the sound paths or part of them with one Covering made of lead can be provided. Even if it is now established that these apparatuses are in the Playback and recording of sounds are at a high level of perfection, so It has turned out that the reproduction of tones, which from others, does not follow the Main patent-manufactured apparatus has been included, is still room for improvement, by making a part of the sound conductor out of leather of those with strangers Apparatus recorded sounds during playback with adherent metallic overtones is taken. Zu diesem Zweck werden einzelne Teile der Schalleitung ganz aus Leder oder abwechselnd aus Leder oder Bleiteilen hergestellt.For this purpose, individual parts of the sound conductor are made entirely of leather or alternately made of leather or lead parts. In der Zeichnung ist die Erfindung an einem Apparat schematisch dargestellt.In the drawing, the invention is shown schematically on an apparatus. Die mit den Buchstaben α bezeichneten Teile werden z. B. aus Leder, die Teile b aus Blei hergestellt; ferner könnte der Schalltrichter aus Bleistreifen c und Lederstreifen d zusammengesetzt sein.The parts marked with the letters α are z. B. made of leather, the parts b made of lead; Furthermore, the horn could be composed of lead strips c and leather strips d . Jedoch könnte auch hierbei ein Materialaustausch vorgenommen werden, so daß die Lederteile durch Bleiteile ersetzt werden und entsprechend die Bleiteile durch Lederteile. Statt massiver Lederteile könnten auch Teile mit Lederbelag oder aus Lederersatz verwendet werden.However, a material exchange could also be made here, so that the Leather parts are replaced by lead parts and accordingly the lead parts by leather parts. Instead of solid leather parts, parts with a leather cover or made from leather substitutes could also be used will.
