KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die in der beiliegenden Zeichnung veranschaulichte Pianinomechanik ist mit einer besonderen Einrichtung zur Auslösung des Stöfsers versehen, durch welche eine sichere Repetition herbeigeführt werden soll.The piano mechanism illustrated in the accompanying drawing has a special one Provided means for triggering the bumpers, by which a safe repetition is to be brought about.
In der Zeichnung stellt dar:In the drawing shows:
. Fig. ι eine Ansicht, bei welcher die wirkenden Theile .sich im Ruhezustande befinden; Fig. 2 eine Stirnansicht zu Fig. 1; Fig. 3 eine Ansicht, bei welcher der Hammer zum Anschlag gebracht ist; Fig. 4 eine Ansicht, bei welcher der Hammer zurückgeht und der Stöfser in Angriffsstellung an die Schulter der Hammernufs gebracht wird.. Fig. Ι a view in which the acting Parts are in a state of rest; FIG. 2 shows an end view of FIG. 1; Fig. 3 a View in which the hammer is brought to the stop; Fig. 4 is a view at which the hammer goes back and the pusher in attack position on the shoulder of Hammernufs is brought.
An dem in der Wippe befestigten Tragstück A ist ein Doppelhebel B drehbar gelagert, in welchem die Feder f befestigt ist und welche durch die Stellschraube s eingestellt werden kann. A double lever B , in which the spring f is fastened and which can be adjusted by the adjusting screw s , is rotatably mounted on the support piece A fastened in the rocker.
Durch Verstellung des Doppelhebels wird der Druck der Feder/ gegen den Stöfser C geregelt, so dafs dieser mehr oder weniger stark nach dem Hülfsarm D zugedrückt wird.By adjusting the double lever, the pressure of the spring / against the pusher C is regulated, so that the pusher C is pressed more or less strongly towards the auxiliary arm D.
Der bei α in dem Stöfser C drehbare Hülfsarm D wird durch eine Feder b auf den Rücken der Hammernufs gedrückt. Durch die Stellschraube d kann die Entfernung des Stöfsers C von dem Hülfsarm D geregelt werden.The auxiliary arm D , which can be rotated in the pusher C at α , is pressed by a spring b onto the back of the hammer nose. The distance between the pusher C and the auxiliary arm D can be regulated by means of the adjusting screw d.
Durch das federnde Zusammenwirken von Stöfser C und Hülfsarm D, sowie dadurch, dafs der Druck der Feder f und die . Entfernung zwischen Stöfser C und Hülfsarm D geregelt werden kann, soll eine sichere Repetition erreicht werden, indem der Stöfser stets sofort wieder in Angriffsstellung an die Schulter E der Hammernufs, und zwar in erwünschter Anschlagwirkung, gebracht wird, und der Gegenhebel hierbei eine sichere Lage der Hammernufs herbeiführen hilft (s. Fig. 4).Through the resilient interaction of the pusher C and the auxiliary arm D, as well as the fact that the pressure of the spring f and the. Distance between the pusher C and auxiliary arm D can be regulated, a safe repetition is to be achieved by the pusher is always immediately brought back into the attack position on the shoulder E of the hammer, and that with the desired impact effect, and the counter-lever is in this case a safe position It helps to bring about a hammer call (see Fig. 4).
Die neue Mechanik kann sowohl mit Oberdärnpfung als auch mit Unterdämpfung ausgeführt werden.The new mechanism can be designed with both upper and lower dampening will.
