Description

Vorrichtung zur Befestigung des Zifferblattes von Taschenuhren. Die Erfindung betrifft eine Vorrichtung zur Befestigung des Zifferblattes von Taschenuhren, bei welcher für jeden von auf der Rückseite des Zifferblattes vorhandenen Befestigungszapfen in einer seitlich desselben liegenden Ausnehmung der Platine eine scharfgängige Anzugschraube drehbar derart angeordnet ist, daß durch Drehen derselben die Gewindegänge sich in das verhältnismäßig zarte Material des Befestigungszapfens. einschneiden und diesen zur Festlegung des Zifferblattes nachziehen. Mittels dieser Vorrichtung läßt sich die Befestigung des Zifferblattes leicht und rasch bewerkstelligen.Device for fastening the dial of pocket watches. the The invention relates to a device for fastening the dial of pocket watches, at which for each of the mounting studs present on the back of the dial in a laterally lying recess of the board a sharp-running one Tightening screw is rotatably arranged so that by turning the same the threads into the relatively delicate material of the mounting pin. incise and retighten it to define the dial. By means of this device the attachment of the dial can be done easily and quickly.

Die Zeichnung veranschaulicht durch Abb. i ein Ausführungsbeispiel des Erfindungsgegenstandes und durch Abb. z eine Einzelansicht.The drawing illustrates an exemplary embodiment by means of Fig. I of the subject matter of the invention and through Fig. z a single view.

a ist das zu befestigende Zifferblatt; das in bekannter Weise auf der Rückseite mit Befestigungszapfen b aus verhältnismäßig zartem Metall, z. B. Kupfer, versehen ist. Jeder Zapfen b steckt in einer etwas weiteren öffnung c der Platine d. Seitlich des Zapfens b ist in einer Ausnehmung f der Platine d eine scharfgängige Anzugschraube g angeordnet. Dieselbe ist mittels eines Zapfens g1 in einer Bohrung der Platine d drehbar gelagert, während sie andernends mittels eines Schraubenziehers um ihre Achse gedreht werden kann. Beim Drehen der Schraube g schneiden sich deren scharfe Gewindegänge in das verhältnismäßig zarte Material des Befestigungszapfen b ein und bewirken dadurch nach und nach ein Nachziehen desselben, bis das Zifferblatt an der Platine festliegt. Da die Schraube g den Zapfen b an mehreren Gängen erfaßt hält, so ist die Befestigung eine feste und zuverlässige.a is the dial to be attached; in a known manner on the back with mounting pin b made of relatively delicate metal, for. B. copper is provided. Each pin b is inserted in a somewhat wider opening c in the board d. A sharp tightening screw g is arranged to the side of the pin b in a recess f of the board d. The same is rotatably mounted by means of a pin g1 in a bore in the plate d, while at the other end it can be rotated about its axis by means of a screwdriver. When the screw g is turned, its sharp threads cut into the relatively delicate material of the fastening pin b, thereby gradually tightening it until the dial is firmly attached to the board. Since the screw g holds the pin b in several turns, the fastening is firm and reliable.
