Description

Durch Patent 330132 ist eine Aufhängevorrichtung für den Motor einer elektrisch angetriebenen Sprechmaschine bekannt geworden, die aus schalldämpfenden Mitteln besteht, wodurch das Geräusch des Motors beim Drehen auf das Gestell der Sprechmaschine nicht übertragen wird und demzufolge beim Vortrag nicht stört.By patent 330132 a suspension device for the motor is an electric one powered talking machine has become known, which consists of sound-absorbing means, reducing the noise of the engine when rotating on the frame of the speaking machine is not transmitted and consequently does not interfere with the lecture.

Die vorliegende Erfindung weist nun insofern eine Verbesserung auf, als das schalldämpfende Mittel nur noch an derjenigen Stelle angebracht ist, welche unmittelbar mit dem Motor in Verbindung steht, während der übrige Teil in beliebiger Weise, insbesondere auch starr, ausgebildet sein kann. Dadurch ist beispielsweise die Verwendung von Gummi als schalldämpfendes Mittel ermöglicht, ohne daß Schwankungen des Motors zu befürchten sind, indem nur ein kurzes Stück von diesem verwendet zu werden braucht, während bei der bekannten Aufhängung infolge der großen freien Länge des Aufhängemittels der vorzüglich schalldämpfende Gummi nicht geeignet ist und außerdem stärkere Schwankungen des Motors unvermeidlich sind.The present invention now has an improvement in that it is sound absorbing Means is only attached at that point, which is directly with the engine is in connection, while the remaining part in any way, in particular can also be rigid. As a result, for example, the use of rubber as a sound-absorbing agent without fear of fluctuations in the engine are by only needing a short piece of this to be used while at the known suspension due to the large free length of the suspension means of the excellent Sound-absorbing rubber is not suitable and, moreover, greater fluctuations in the engine are inevitable.

Der Gegenstand der Erfindung ist auf der Zeichnung in beispielsweiser Ausführungsform veranschaulicht. The object of the invention is illustrated in the drawing in an exemplary embodiment.

*) Früheres Zusatzpatent 331903.*) Former additional patent 331903.

Abb. ι zeigt die Anordnung des Motors im Apparat in Draufsicht.Fig. Ι shows the arrangement of the motor in the apparatus in plan view.

Abb. 2 ist eine Draufsicht auf die Aufhängung selbst.Fig. 2 is a top plan view of the suspension itself.

Bei der dargestellten Ausführungsform ist der Motor α an dem aus starrem Material bestehenden Tragrahmen b nicht unmittelbar festgemacht, sondern es ist zwischen Motor α und Tragrahmen b ein Körper c zwischengelegt, welcher aus einem Material besteht, .welches den Schall nicht oder nur schlecht leitet, wie z. B. Gummi. Der Motor α ist nun an diesem Material c aufgehängt und seine Befestigungsschrauben d sind in diesen Zwischenstücken c festgemacht.In the embodiment shown, the motor α is not directly fastened to the support frame b made of rigid material, but a body c is interposed between the motor α and the support frame b , which consists of a material which does not or only poorly conducts the sound. such as B. rubber. The motor α is now suspended from this material c and its fastening screws d are fastened in these intermediate pieces c.

Die Form dieser Zwischenstücke c ist beliebig. Die Rahmenteile b können gegebenenfalls drehbar um ihre Achsen g angeordnetThe shape of these intermediate pieces c is arbitrary. The frame parts b can optionally be arranged to be rotatable about their axes g
