PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft eine Schleifvorrichtung für Tischmesser.The present invention relates to a grinding device for table knives.
In der beiliegenden Zeichnung zeigt Fig. 1 den Erfindungsgegenstand im Querschnitt, während Fig. 2 eine schaubildliche Ansicht einer der Schleifscheiben zeigt.In the accompanying drawing, Fig. 1 shows the subject of the invention in cross section, while Fig. 2 shows a perspective view of one of the grinding wheels.
α bezeichnet ein Gufsgestell, welches mit einem Ansatz b versehen ist, der eine Klemmschraube c enthält. Mit der so gestalteten Schraubzwinge wird die Vorrichtung im Hausgebrauche an einer Tischkante festgeklemmt. Sodann trägt das Gufsgestell a die aufrechten, angegossenen Streben d und d1, die die Lager für eine Welle e enthalten. Auf dieser Welle sind die Schleifscheiben f befestigt. α denotes a cast frame which is provided with a shoulder b which contains a clamping screw c. With the screw clamp designed in this way, the device is clamped to the edge of a table for domestic use. Then the cast frame a carries the upright, cast-on struts d and d 1 , which contain the bearings for a shaft e. The grinding wheels f are attached to this shaft.
Diese Schleifscheiben bestehen aus Schmirgel oder Carborund und sind mit keilartigen Ansätzen g versehen, die in regelmäfsigen Abständen auf der Scheibe um den Mittelpunkt so vertheilt sind, dafs die Abstände zwischen je zwei benachbarten Ansätzen g genau die Breitenabmessungen haben, wie die Ansätze selbst. Es werden dann die Scheiben mit ihren keilartigen Ansätzen so gegen einander gerichtet auf der Welle e befestigt, dafs die Ansätze einer Scheibe in die Zwischenräume zwischen den Ansätzen der anderen Scheibe eingreifen.These grinding wheels consist of emery or carborundum and are provided with wedge-like extensions g , which are distributed at regular intervals on the disk around the center so that the distances between each two adjacent extensions g have exactly the same width as the extensions themselves Then the disks with their wedge-like projections facing each other are fastened on the shaft e in such a way that the projections of one disk engage in the spaces between the projections of the other disk.
Die Messerscheide, die., in die entstandene umlaufende Vertiefung zwischen beiden Scheiben hineingehalten wird, wird dann von den sich im spitzen Winkel schneidenden Kanten der Keilflächen geschärft. Den Antrieb empfängt die Welle e von einem Kurbel- und Zahnradgetriebe.The knife sheath, which is held in the resulting circumferential recess between the two disks, is then sharpened by the edges of the wedge surfaces that intersect at an acute angle. The drive receives the shaft e from a crank and gear transmission.
