PATENTSCHRIFT
KLASSE 68: Schlosserei.
THEODOR KROMER in FREIBURG (Baden) Stufenschlüssel.
Patentirt im Deutschen Reiche vom 12. April 1888 ab.
Die gebräuchlichen Cassaschlüssel, wie sie in Fig. ι abgebildet sind, können eventuell durch Abformen u. s. w. nachgebildet werden.
Diese Nachbildung wird ganz wesentlich erschwert, wenn die Schlüsselbärte Aushöhlungen haben, und namentlich dann, wenn solche über die Mittellinie des Schlüsselbartes hinausgehen, wie in Fig. 2, wodurch ein directes Abformen möglichst verhindert werden soll.
Die zu diesem Zweck gemachten Aushöhlungen am Ende der Stufen können die verschiedenste Form haben, wie Fig. 3 und 4, wobei aber immer die Aushöhlung über die Mittellinie des Schlüssels hinauszugehen hat.
Diese Aushöhlungen können an allen oder nur an einzelnen Stufen angebracht werden.

Claims (1)

  1. Patent-Anspruch:
    Zum Zweck der Erschwerung der Nachbildung von Stufenschlüsseln die Aushöhlung einzelner oder aller Stufenenden über die Mittellinie des Bartes hinaus.
    Hierzu 1 Blatt Zeichnungen.
