Description
Notenblattwender. Es sind bereits Notenblattwender bekannt, bei denen mehrere Bügel nacheinander durch einen mittels einer Feder schwenkbaren Stift herumgelegt werden. Das Neue besteht darin, daß ,sich dieser Stift in einem auf und ab steigenden Führungsschlitze bew egt und, im oberen Teil des Schlitzes laufend, die Bügel mitnimmt und sie, sobald er in den unteren Teil eintritt, freigibt.Sheet music turner. There are already known sheet music inverters in which several brackets placed around one after the other by a pin pivotable by means of a spring will. The new thing is that, this pen is in an ascending and descending manner Guide slots moves and, running in the upper part of the slot, takes the bracket with it and releases them as soon as he enters the lower part.
In einer beispielsweisen Ausführungsform ist der Gegenstand der Erfindung auf der Zeichnung dargestellt.In an exemplary embodiment, the subject of the invention is shown on the drawing.
Die Bügel a -werden unter die einzelnen Notenblätter gelegt. Die aufgezogene Feder b mit dem Mitnehmerstift c drückt ihn gegen. ,den ersten Bügel a. Ist nun der Zeitpunkt gekommen, wo das betreffende Notenblatt umzuwenden ist, .so berührt der Spieler den Hebel d; dadurch wird die Feder b freigtgeben und, durch ihre Federkraft gezwungen, bewegt,der Mitnehmerstift c den Bügel a und mit ihm auch das Notenblatt im Halbkreis von rechts nach links und legt es so um. Sobald dies geschehen ist, wird das freie Ende der .Feder und damit auch' der Mitnehmerstift c durch eine im Gehäuse befindliche schräge Bahn e nach unten gezogen, löst sich ,dadurch vom Bügel a los und gibt ihn frei. Der Mitnehmerstift bewegt sich nun während der zweiten halben Umdrehung heruntergezogen durch die im Gehäuse befindliche Bahn d; bis er kurz vor Vollendung einer ganzen Umdrehung, durch diese gezwungen, wieder an die Oberfläche gelangt und sich hinter den zweiten Bügel a legt. Die Feder b' und somit auch der Mitnehmerstift c werden aber an der sofortigen weiteren Drehung durch den Hebel d gehindert, bis der Spieler diesen löst und das nächste Notenblatt umgelegt wird. Ein Sperrad mit Klinke arretiert die Feder beim Aufziehen.The brackets a are placed under the individual sheet music. The drawn-up spring b with the driver pin c presses it against it. , the first bracket a. If the time has come when the sheet of music in question is to be turned over, the player touches lever d; this releases the spring b and, forced by its spring force, moves the driver pin c the bracket a and with it the sheet music in a semicircle from right to left and so turns it over. As soon as this has happened, the free end of the .spring and thus also the driver pin c is pulled down through an inclined path e located in the housing, becomes detached, thereby loosing itself from the bracket a and releases it. The driver pin now moves during the second half turn pulled down through the path d in the housing; until it comes to the surface again shortly before completing a full turn, forced by this, and lies behind the second bracket a. The spring b 'and thus also the driver pin c are prevented from immediate further rotation by the lever d until the player releases it and the next sheet of music is turned over. A ratchet wheel with a pawl locks the spring in place when it is wound.
