Patentirt im Deutschen Reiche vom 23. September 1881 ab.Patented in the German Empire on September 23, 1881.

Auf beiliegender Zeichnung sind in Fig. 1 und 2 zwei Resonanzböden A und B im Querschnitt dargestellt, welche durch den nachstehend beschriebenen Mechanismus verbunden sind. An beiden Resonanzböden sind Rippen a und b von gleicher oder ungleicher Höhe, in letzterem Falle mit an die schwächeren Rippen b angesetzten Verstärkungsstücken c befestigt, und an diese sind mittelst je einer Holzschraube die flachen Holzstäbe α1 und b1 angeschraubt, welche von einer dritten Holzschraube in der Mitte zusammengehalten werden. Der durch die Holzschrauben bewirkte Anzug soll eine directe Uebertragung der Schwingungen des einen Resonanzbodens auf den anderen bedingen, ohne jedoch das Schwingungsvermögen jedes einzelnen zu beeinträchtigen. Derartige Schwingungsübertrager werden in beliebiger Anzahl zwischen beiden Resonanzböden eingeschaltet. In the accompanying drawing, two soundboards A and B are shown in cross-section in FIGS. 1 and 2, which are connected by the mechanism described below. Ribs a and b of the same or unequal height are attached to both soundboards , in the latter case with reinforcement pieces c attached to the weaker ribs b , and the flat wooden rods α 1 and b 1 are screwed to these by means of a wood screw, which are screwed by a third Wood screw held together in the middle. The tightening caused by the wood screws should cause a direct transmission of the vibrations of one soundboard to the other, without, however, impairing the vibrational capacity of each individual. Any number of such vibration transmitters can be switched on between the two soundboards.

Claims (1)

Patent-Anspruch:Patent claim: Eine Vorrichtung zur Uebertragung der Schwingungen von einem Resonanzboden auf den anderen, bestehend aus einer durch zwei Stäbchen a1 und b1 gebildeten Gelenkverbindung, deren Enden so mit den Resonanzböden durch riachziehbare Holzschrauben verbunden sind, dafs letztere frei schwingen können, ohne dabei die Verbindung selbst und ihre Uebertragungsfähigkeit aufzuheben.A device for the transmission of vibrations from one soundboard to the other, consisting of an articulated connection formed by two rods a 1 and b 1 , the ends of which are connected to the soundboards by adjustable wood screws so that the latter can vibrate freely without the connection itself and cancel their transferability.
