Description
messerschärfer, bei dem die beiderseitig der Klinge angeordneten Schärfbacken aus schraubengangförmig gewundenen Kantenleisten bestehen. Die Erfindung betrifft einen, Messerschärfer, der nach Art der .bekannten Schärfer arbeitet, die im wesentlichen aus zwei Walzen mit ring- oder walzenförmigen, in regelmäßigen Abständen angebrachten Erhöhungen bestehen und so nebeneinander liegen, daß diese Erhöhungen wechselseitig in die dazwischen gebildeten Nuten eingreifen.knife sharpener, with the sharpening jaws arranged on both sides of the blade consist of helically wound edge strips. The invention relates to a knife sharpener that works in the manner of the known sharpeners, which are essentially from two rollers with ring-shaped or cylindrical-shaped, attached at regular intervals Elevations exist and lie side by side in such a way that these elevations are reciprocal engage in the grooves formed in between.
In dem Einschnitt, welchen die ring- oder walzenförmigen Erhöhungen der nebeneinander angeordneten Walzen bilden, wird die Schneide des Messers senkrecht unter Druck hin und hier geführt ,und[ dadurch, abgeschliffen bzw. geschärft.In the incision, which the annular or cylindrical elevations of the rollers arranged next to one another, the cutting edge of the knife becomes vertical guided here and there under pressure, and [thereby, ground or sharpened.
Die Walzen dieser bekannten Messerschärfer sind aus Stahl gedreht; die Herstellung dieser Walzen ist teuer, der Verbrauch an Material groß.The rollers of this known knife sharpener are turned from steel; the manufacture of these rollers is expensive, and the consumption of material is great.
Durch vorliegende Erfindung wird nun vorgeschlagen, diese Walzen durch zwei schraubenbga:ngförmig gewundene Kantenleisten zu ersetzen, -die in die gegenseitigen Nuten eingreifen. Die Zeichnung stellt den Gegenstand der Erfindung dar, und zwar zeigen: Fig. r eine Seitenansicht, Fig. 2 eine Ansicht von, oben, Fig. 3 .eine Ansicht von vorn.By the present invention it is now proposed to use these rollers two screw bga: ng-shaped winding edge strips to replace, -those in the mutual Engage grooves. The drawing represents the subject of the invention, namely show: FIG. 1 a side view, FIG. 2 a view from above, FIG. 3 a view from the beginning.
Durch Wickeln einer Walze aus Vierkant oder Flachstahl wird ohne weiteres erreicht, da.ß die einzelnen Gänge scharfe Kanten. bilden, die auf Schneide stehen..By winding a roller made of square or flat steel is easily achieved that the individual courses had sharp edges. who are on the cutting edge ..
Gegenüber den massiven Walzen haben diese Walzen aus kantigem Stahldraht außer der billigeren Herstellungsweise und der großen Materialersparnis den Vorzug, daß eine gewisse Federung beim Hin und Herführen des Messers unter Druck stattfindet, die das Schärfen des Messers beschleunigt.Compared to the massive rollers, these rollers are made of angular steel wire apart from the cheaper production method and the great savings in material, the advantage that there is a certain resilience when moving the knife back and forth under pressure, which speeds up the sharpening of the knife.
Um .ein besseres Ineinandergreifen der einzelnen Gänge zu Ermöglichen, laufen die Windungen der Kantenleisten vorteilhaft entgegengesetzt zueinander.In order to enable the individual courses to mesh better, the turns of the edge strips advantageously run opposite one another.
Um ein seitliches Ausweichen der Kantenleisten a infolge des Druckes beim Hin- und Herführen -des Messers zwischen den Walzen zu verhindern, sind diese auf einer Platte b mittels eines Stabes c von der ungefähren Breite des inneren Durchmessers der Walze befestigt.To a sideways evasion of the edge strips a as a result of the pressure When moving the knife back and forth between the rollers, these are to be prevented on a plate b by means of a rod c of the approximate width of the inner one Fixed diameter of the roller.
Der Stab c ist vorteilhaft an beiden Enden gekröpft, um ein Verschieben der gewundenen Kantenleisten auch in der Längsrichtung zu verhindern.The rod c is advantageously cranked at both ends so that it can move to prevent the sinuous edge strips also in the longitudinal direction.
Die beschriebene Befestigung kann so ausgebildet sein, daß die gewundenen Kantenleisten drehbar sind.The attachment described can be designed so that the winding Edge strips are rotatable.
