Zahnbefestigung an Kreissägen. Patentiert im Deutschen Reiche vom 9.November 1915 ab..Tooth attachment on circular saws. Patented in the German Empire on November 9, 1915 ..
In stark beanspruchte Sägen, wie z. B. in Kaltkreissägen, werden besondere Zähne aus Hartstahl in das Blatt eingesetzt. Das Einsetzen geschieht mit Hilfe von Nut und Feder, und es findet dann eine besondere Befestigung durch Splinte, Keile o. dgl. statt. Die Herstellung solcher Zähne sowie das Einsetzverfahren ist zeitraubend und kostspielig, und die Zähne werden trotzdem oft locker.In heavily used saws, such as. B. in cold circular saws, special teeth are made High carbon steel inserted into the blade. The insertion is done with the help of tongue and groove, and there is then a special fastening by cotter pins, wedges or the like. The production such teeth and the method of insertion are time consuming and costly, and the teeth often become loose.
ίο Bei der vorliegenden Erfindung zeigen sich diese Nachteile nicht. Die Befestigung der Zähne ist sehr einfach und dauerhaft.ίο In the present invention show these disadvantages do not. The attachment of the teeth is very easy and permanent.
Die neue Befestigung besteht darin, daß die in die Ausschnitte α des Sägeblattes einzusetzenden Zähne b an Brust oder Rücken oder an beiden mit feinen Längsrippen versehen sind, während die entsprechenden Flächen des Ausschnittes eben bleiben. Die Zähne werden durch Pressen oder Schlagen in die Einschnitte eingetrieben und sitzen dann ohne besonderes Befestigungsmittel fest.The new fastening consists in that the teeth b to be inserted into the cutouts α of the saw blade are provided with fine longitudinal ribs on the chest or back or on both, while the corresponding surfaces of the cutout remain flat. The teeth are driven into the incisions by pressing or hitting and then sit firmly without any special fasteners.
