PATENTAMT.PATENT OFFICE.
Die vorliegende Oktavenkupplung benutzt die bekannten zweiarmigen Wellen. Der ganze Kupplungsapparat ist vorn unter den Tasten so angebracht, daß die Drehrichtung der Arme in einer Richtung mit der Drehrichtung der Tasten liegt.The present octave coupling uses the well-known two-armed shafts. The whole Coupling device is attached in front under the buttons so that the direction of rotation of the arms is in the same direction as the direction of rotation of the buttons.
Fig. ι zeigt eine Draufsicht der Verbindungen für eine Oktave,Fig. Ι shows a top view of the connections for an octave,
Fig. 2 eine Seitenansicht derselben.Fig. 2 is a side view of the same.
Auf der Grundplatte ι sind die Ständer 2 befestigt, die der Welle 3 als Lager dienen. An den beiden Enden der Welle· 3 befinden sich die beiden mit ihr fest verbundenen Arme 4 und 5. Auf den Arm 4 wirkt das in der Taste 7 eingeschraubte Druckmittel 6. Der Arm 5 liegt über dem Zugmittel 8 der Taste 9, die mit der Taste 7 eine Oktave bildet. Der auf den Arm 4 von der Taste 7 ausgeübte Druck wirkt daher vermittels der Welle 3 auf den Arm 5, welcher die Taste 9 mit derselben Kraft herunterzieht, mit der die Taste 7 angeschlagen wurde.The stands 2, which serve as bearings for the shaft 3, are fastened to the base plate. At the two ends of the shaft 3 are the two firmly connected to it Arms 4 and 5. The pressure medium 6 screwed into the button 7 acts on the arm 4. The arm 5 lies above the traction means 8 of the key 9, which forms an octave with the key 7. The pressure exerted on the arm 4 by the button 7 therefore acts by means of the Shaft 3 on the arm 5, which pulls the button 9 down with the same force with the button 7 has been pressed.
