  Verfahren zur Herstellung von Schlüsseln. 



   Die Erfindung richtet sich auf die Aufgabe, Schlüssel in möglichst einfacher Weise herzustellen, und besteht darin, dass aus starkem Blech ein Formstück roh ausgestanzt, in einer Lauge blank gescheuert, in einer Vorpresse zweckmässig mit gerundetem Schaft versehen und sonst vorgeformt, in einem Polierwerkzeug nachgepresst wird, u. zw. so, dass die Rundungen des Schlüsselbartes zum Bewegen der Zuhaltungen u. dgl. ebenfalls durch Prägung geformt werden,   zweckmässig   beim Nachprägen im Polierwerkzeug. Hiedurch wird ein Schlüssel erzielt, dessen glatte harte Politur ihn ausserordentlich widerstandsfähig gegen Rost macht. Die Herstellung der   Schlüsselbartrundungen   durch Pressen ist besonders wichtig, da sie die sonst üblichen Handarbeiten entbehrlich macht.

   Aus dem gerundeten Schaft kann eine in Richtung des   Schlüsselbartes sich erstreckende Verstärkungsrippe   bestehen bleiben, wodurch dem Schlüssel eine besondere Festigkeit gegeben wird. 



     PATENT-ANSPRÜCHE   :
1. Verfahren zur Herstellung von Schlüsseln, dadurch gekennzeichnet, dass ein aus starkem Blech roh ausgestanztes Formstück in einer Lauge blank gescheuert, in einer Vorpresse   zweckmässig   mit einem gerundeten Schaft versehen und sonst vorgeformt und in einem Polierwerkzeuk nachgeformt wird.

  Method of making keys.



   The invention is directed to the task of producing keys in the simplest possible way, and consists in punching out a rough molded piece from strong sheet metal, scrubbing it blank in a lye, suitably provided with a rounded shaft in a pre-press and otherwise preformed and re-pressed in a polishing tool we you. zw. So that the curves of the key bit to move the tumblers u. Like. Also shaped by embossing, useful when re-embossing in the polishing tool. This produces a key whose smooth, hard polish makes it extremely resistant to rust. The production of the key bit rounding by pressing is particularly important because it makes the otherwise usual manual work unnecessary.

   A reinforcing rib extending in the direction of the key bit can remain from the rounded shaft, which gives the key a particular strength.



     PATENT CLAIMS:
1. A process for the production of keys, characterized in that a blank stamped out of strong sheet metal is rubbed bare in a lye, suitably provided with a rounded shaft in a pre-press and otherwise pre-formed and post-formed in a polishing tool.
