PATENTAMT.PATENT OFFICE.
In vergrößertem Mafsstabe zeigt Fig. 1 die geöffnete, Fig. 2 die geschlossene Vorrichtung, welche ein leichtes Auswechseln und Einsetzen von Brillen- oder Klemmergläsern ohne weitere Hülfsmittel gestattet.On an enlarged scale, Fig. 1 shows the open, Fig. 2 the closed device, which an easy replacement and insertion glasses or Klemmer lenses are permitted without additional aids.
Der Ring r, welcher das Glas g umfafst, ist, wie üblich, getheilt. Durch die mit Verdickungen d versehenen Stofsenden ist jedoch keine Schraube gezogen, sondern es ist darin je ein Draht \ h2 derart eingebogen, dafs beide zusammen · mit den Enden d des Ringes ein Hebelwerk bilden, das durch einfaches Umlegen die Enden d zusammendrückt und durch Ueberbringen über seinen todten Punkt sich gegen unbeabsichtigtes Lösen sichert.The ring r, which embraces the glass g , is, as usual, divided. However, no screw is pulled through the ends of the fabric provided with thickenings d , but rather a wire 2 is bent in each in such a way that both together with the ends d of the ring form a lever mechanism which, by simply turning over, presses the ends d together and pushes through Bringing over its dead point secures itself against unintentional loosening.
