Description
Schärfvorrichtung mit mehreren Einsätzen verschiedenartiger Schleifwirkung (grob und fein), insonderheit zum Schärfen und Abziehen der Messer an landwirtschaftlichen Maschinen. Die Erfindung bezieht sich auf ein Schärfwerkzeug, insonderheit für die Schneidmesser von landwirtschaftlichen Maschinen u. dgl., und besteht in der eigenartigen Ausbildung des Schärfwerkzeuges, das ein Schleifen und Abziehen der Messer ermöglicht, ohne daß die Abnahme des Messers oder eine besondere Einstellung des Schärfwinkels am Werkzeug erforderlich ist. Das selbsttätige Einstellen des Schärfwinkels entsprechend der Messerschneide wird dadurch erzielt, daß die Schärffeilen in ihrem Halter leicht drehbar befestigt sind und sich so der Messerschneide anpassen können. Das Werkzeug ist in der Zeichnung dargestellt, und zwar zeigen Fig. z eine Seitenansicht, Fig. a eine Ansicht von oben.Sharpening device with several inserts of different types of grinding effect (coarse and fine), especially for sharpening and honing the knives on agricultural machines Machinery. The invention relates to a sharpening tool, in particular for Agricultural machinery cutter and the like, and consists of the peculiar Training of the sharpening tool, which enables the knife to be sharpened and honed, without removing the knife or adjusting the sharpening angle is required on the tool. The automatic adjustment of the sharpening angle accordingly the knife edge is achieved in that the sharpening files are easily in their holder are rotatably attached and can thus adapt to the knife edge.

Der Bock a ist mit zwei Handgriffen versehen und. in der Mitte mit gegenüberliegenden Aussparungen b, die mit einem- als Führung für das zu schärfende Messer dienenden Metallfutter c ausgekleidet sind. Die Aussparungen b des Bockes a werden beiderseitig von Platten d begrenzt, die gleichzeitig als Lager für die Stellschrauben g dienen. Die Stellschrauben g sind beiderseitig in die Lagerplatte d eingeschraubt; sie laufen hinter dem Gewinde in glatte Zapfen i aus, die in die zentrischen Bohrungen 1? der Vierkantfeilen f eingreifen. Die Feilen können sich leicht um ihre Achse drehen und beim Aufsetzen des Werkzeuges selbsttätig auf den Winkel der Schneidenflächen des zu.schärfenden Sclmeidmessers einstellen. Die Feilen haben verschiedenen Hieb, so daß mit der einen vorgeschärft und mit der anderen abgezogen werden kann.The bracket a is provided with two handles and. in the middle with opposite recesses b, which are lined with a metal chuck c serving as a guide for the knife to be sharpened. The recesses b of the bracket a are bounded on both sides by plates d, which also serve as bearings for the adjusting screws g. The adjusting screws g are screwed into the bearing plate d on both sides; they run out behind the thread in smooth pegs i, which are inserted into the central bores 1? the square files f engage. The files can easily rotate around their axis and automatically adjust to the angle of the cutting surfaces of the cutting knife to be sharpened when the tool is placed. The files have different cuts so that you can pre-sharpen with one and sharpen with the other.
