KLASSE 68: Schlosserei.CLASS 68: Locksmith.
Patentirt im Deutschen Reiche vom ag. Februar 1884 ab.Patented in the German Empire by ag. February 1884 onwards.
Fig. ι der Zeichnung ist ein zweitouriges Einsteck-Thürschlofs. Der zur Sicherung des Drückerverschlusses oder sogen. Tagesriegels a a angeordnete Schutzriegel b b, dargestellt in Fig. 2, mit darunterliegender, in Fig. 3 dargestellter Zuhaltung, liegt derart im Schlofsgehäuse, dafs der Hauptriegel c e sich beim Aufschliefsen der Thür über denselben schiebt. Die Entfernung dieses Schutzriegels bezw. Freistellung des Tagesriegels kann nur mittelst des zum Schlosse gehörigen Schlüssels erfolgen. Der Bart des Schlüssels, Fig. 4, ist mit einem der Dicke des Schutzriegels b b entsprechenden Einschnitte ver-; sehen, damit das obere Bartende die punktirt gezeichnete Zuhaltung des Schutzriegels zurückdrängen kann. Das Aufschliefsen mittelst des zugehörigen Schlüssels bewirkt zunächst halbe Zurückziehung des Hauptriegels c c, beim Weiterdrehen halbe Zurückziehung des Schutzriegels b b, sodann Freistellung des Hauptriegels c c und erst hiernach völlige Freistellung des Tagesriegels α α zum Oefrhen mittelst Thürdrückers. Selbst wenn also ein genau ins Schlüsselloch passender Schlüssel ohne den genau auf den Schutzriegel b b passenden Einschnitt angewendet würde, bleibt der Tagesriegel gesichert, während ein Dietrich zu dessen Freistellung nicht angewendet werden kann, weil eben der Hauptriegel beim Aufschliefsen sich über den Schutzriegel b b schiebt.Fig. Ι of the drawing is a two-speed plug-in Thürschlof. The to secure the handle lock or so-called. Daytime bolt aa arranged protective bolt bb, shown in Fig. 2, with underlying tumbler shown in Fig. 3, lies in the lock housing in such a way that the main bolt ce slides over the same when the door is unlocked. The removal of this protective bar respectively. The day bolt can only be released using the key belonging to the lock. The beard of the key, FIG. 4, is provided with an incision corresponding to the thickness of the protective bar bb; see so that the upper end of the beard can push back the dotted drawn guard locking of the safety bar. The unlocking by means of the associated key initially causes half retraction of the main bolt cc, when turning it half retraction of the protective bolt bb, then release of the main bolt cc and only then complete release of the day bolt α α for opening by means of the door handle. So even if a key that fits exactly into the keyhole is used without the cut that exactly fits the safety bolt bb , the day bar remains secured, while a lockpick cannot be used to release it, because the main bolt slides over the safety bar bb when unlocking.
