Description

Stimmwirbel für Klaviere. Gegenstand der Erfindung ist ein Stimmwirbel für Klaviere mit metallenem Stimmstock, der bezweckt, eine dauerhaftere Stimmhaltung zu erzielen. In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt.Tuning pegs for pianos. The invention relates to a tuning peg For pianos with a metal sound post, which aims to achieve a more permanent vocal position to achieve. In the drawing is an embodiment of the subject matter of the invention shown.

Durch den festeren Sitz des Wirbels b im Metallrahmen a ist ein Federn und Nachgeben des Wirbels ausgeschlossen. Festigkeit erhält der -Wirbel dadurch, daß derselbe konisch abgedreht finit einer Messinghülse c in dem Eisenrahmen a sitzt und durch eine Feder f, die durch eine Schraubenmutter g nachstellbar ist, im Konus c festgezogen wird. Ein Lösen der Mutter beim Drehen des Wirbels wird durch eine mit einer Nase versehene Unterlegscheibe e aus Stahl in -der Weise verhindert, daß die Nase in eine im Wirbel befindliche Nute h greift. . Um Reibung und Festrosten von Stahl und Eisen zu vermeiden, befindet sich zwischen Unterlegscheibe e und Metallrahmen a eine Fiberscheibe d.The tighter fit of the vertebra b in the metal frame a prevents the vertebra from springing and yielding. The vortex receives strength from the fact that it sits conically twisted finitely with a brass sleeve c in the iron frame a and is tightened in the cone c by a spring f, which can be readjusted by a screw nut g. A loosening of the nut when turning the vertebra is prevented by a washer e made of steel with a nose in such a way that the nose engages in a groove h in the vertebra. . To prevent steel and iron from rubbing and rusting, there is a fiber washer d between the washer e and the metal frame a.
