Fig. ι zeigt den Stimmschlüssel in der vorderen Ansicht, Fig. 2 in der oberen Ansicht, Fig. 3, 4 und 5 sind Details.Fig. Ι shows the tuning key in the front view, Fig. 2 in the upper view, Figures 3, 4 and 5 are details.
Auf der Welle A, Fig. 1 und 2, ist das Stirnrad B befestigt, welches sich zwischen den Platten C und D, in deren Mittelpunkt sich gleichzeitig die Lager für die Welle A befinden, bewegt. In das Stirnrad B greift die Schraube JS, •deren Achse eine geneigte Lage hat, Fig. 1. F sind die Lager für die Schraube. An diesen befinden sich die Zwischenstücke G, an welchen die Platten C und D mittelst Schrauben befestigt sind und. die den Raum für das Stirnrad feststellen. On the shaft A, Fig. 1 and 2, the spur gear B is attached, which moves between the plates C and D, in the center of which the bearings for the shaft A are located at the same time. The screw JS engages in the spur gear B , • the axis of which is inclined, Fig. 1. F are the bearings for the screw. On these are the intermediate pieces G, to which the plates C and D are fastened by means of screws and. which determine the space for the spur gear.
Die Schraube K, Fig. 1, dient zur Befestigung des Stimmkopfes H an der Welle A. Der Stimmkopf H hat eine vierseitige Oeffnung h, Fig. 4, zur Aufnahme des Stimmnagels, und eine Bohrung, Fig. 3, der Welle A entsprechend.The screw K, Fig. 1, is used to fasten the tuning head H to the shaft A. The tuning head H has a four-sided opening h, Fig. 4, for receiving the tuning nail, and a hole, Fig. 3, corresponding to the shaft A.
An der unteren Platte D, Fig. 1, befinden sich die Füfse J. Diese bewirken beim Gebrauch des Stimmschlüssels ein Feststehen' desselben, indem sich dieselben alsdann an die zunächst stehenden Stimmnägel anlegen und hierdurch ein Mitgleiten des Mechanismus verhindern.On the lower plate D, Fig. 1, there are the feet J. When the tuning key is used, these cause the same to stand in place, in that they then rest against the initially standing tuning pins and thereby prevent the mechanism from sliding along.
Durch die Uebertragung der Kraft mittelst der Schraube ohne. Ende soll es selbst dem Laien möglich sein, in kürzester Zeit ohne grofse Kraftanwendung ein jedes Instrument chromatisch rein zu stimmen.By transmitting the force by means of the screw without. It should end even that Laypeople can use every instrument chromatically in a very short time without the use of great force to vote pure.
