Description

Die in Zeichnung dargestellte Mechanik unterscheidet, sich dadurch von allen bekannten Repetitionsmechaniken für Flügel, dafs dieselbe mit nur einer Feder versehen ist, welche gleichzeitig Stöfserfeder und Repetitionsfeder ist; aufserdem ist das Uebergewicht des Hammers aufgehoben und die Zahl der Glieder verringert.The mechanics shown in the drawing distinguish differs from all known repetition mechanisms for grand pianos in that the same with only one spring is provided, which is simultaneously a push spring and repetition spring; besides the overweight of the hammer is eliminated and the number of limbs reduced.

Die Nufs α des Hammers h .ist am unteren Ende mit einem Stiel b versehen, dessen freies Ende durch eine Schnur g mit einer Feder d verbunden ist, welche sich um einen im Stöfser c befestigten Stift e dreht. Die Feder ist um den Stift e herumgewunden; gegen die Verlängerung über e hinaus wirkt die Regulirschraube /, welche so angezogen wird, dafs das Uebergewicht des Hammers h durch die Anspannung der Schnur g nahezu aufgehoben ist.The base α of the hammer h. Is provided at the lower end with a handle b , the free end of which is connected by a cord g to a spring d which rotates around a pin e fixed in the pusher c. The spring is wound around the pin e; the regulating screw / acts against the extension beyond e , which is tightened in such a way that the excess weight of the hammer h is almost eliminated by the tension of the cord g.

Sobald der Hammer h durch Anschlag der Taste i an die Saite k gebracht wird, wird die Wirkung der Feder d auf b und h etwas schwächer infolge der drehenden Bewegung von b, wodurch der Hammer eben frei auslöst, indem das Oberende des Stöfsers c in den Ausschnitt der Nufs α tritt. Läfst man darauf die Taste etwas zurückgehen, damit der Hammer wieder fällt, so tritt sofort die ursprüngliche Spannung der Feder d wieder ein und bringt dieselbe den Stöfser c wieder unter die Nufs a. Durch erneuten geringen Druck auf die Taste i erfolgt wieder der Anschlag des Hammers gegen die Saite u. s. f.As soon as the hammer h is brought to the string k by striking the key i , the effect of the spring d on b and h becomes somewhat weaker as a result of the rotating movement of b, whereby the hammer releases freely by pushing the upper end of the pusher c into the Section of the Nufs α occurs. If you then let the key go back a little so that the hammer falls again, the original tension of the spring d is immediately restored and it brings the pusher c back under the nufs a. Another slight pressure on the i key causes the hammer to strike the string, etc. again
