Zusatz zum Patente 94967 vom 23. März 1897.Addendum to patent 94967 of March 23, 1897.

Patentirt im Deutschen Reiche vom 3. November 1898 ab. Längste Dauer: 22. März 1912.Patented in the German Empire on November 3, 1898. Longest duration: March 22, 1912.

Gegenstand vorliegender Erfindung bildet eine weitere Ausbildung des Gegenstandes des Anspruches 1 des Patentes 94967, wobei statt der Trommel D (vergl. Fig. 1 des Haupt-Patentes) eine Scheibe P (Fig. 1) angeordnet ist, welche von ihrem gröfsten Durchmesser aus nach einer Seite derartig konisch bezw. in Form eines Kegelstumpfes abgedreht ist, dafs die hierdurch entstandene Mantelfläche S zur Scheibenachse in einem mehr oder weniger spitzen Winkel steht.The subject of the present invention forms a further embodiment of the subject matter of claim 1 of patent 94967, wherein instead of the drum D (see one side such conical BEZW. is turned off in the form of a truncated cone, that the resulting lateral surface S is at a more or less acute angle to the disk axis.

In die Mantelfläche S der Scheibe P werden nun die Vertiefungen eingearbeitet, in welche die Werkstücke beim Schleifen einzulegen und zu befestigen sind. Es können jedoch auch schwalbenschwanzförmige oder anders geformte Rinnen in die Mantelfläche S eingehobelt werden, welche Schleifformen aufnehmen, wie solche (mit dem Buchstaben B bezeichnet) im Haupt-Patent 94967 angeordnet sind. Die Befestigungsweise der Werkstücke findet (wie auch im Haupt-Patent angegeben) in bekannter Weise statt.The indentations into which the workpieces are to be inserted and fastened during grinding are now worked into the outer surface S of the disk P. However, dovetail-shaped or differently shaped grooves can also be planed into the outer surface S , which take up grinding shapes such as those (denoted by the letter B ) in the main patent 94967. The method of fastening the workpieces takes place (as also indicated in the main patent) in a known manner.

In Fig. 2 ist eine Scheibe A dargestellt, welche sich von Scheibe P nur dadurch unterscheidet, dafs sie einen doppelten Kegelstumpf bildet.In Fig. 2 a disk A is shown, which differs from disk P only in that it forms a double truncated cone.

In Fig. 3, einem Ausschnitt der Scheibe A (Fig. 2), sind die schwalbenschwanzförmigen Rinnen von oben zu sehen.In Fig. 3, a section of the disk A (Fig. 2), the dovetail grooves can be seen from above.

Auch Fig. 4 ist ein Ausschnitt der Scheibe A mit eingehobelten Rinnen für die Schleifformen B (vergl. Fig. 1 des Haupt-Patentes), doch werden diese Rinnen hier in etwas anderer, und zwar in einer solchen Anordnung angebracht, wie sie auch zur Scheibe P (Fig. 1) anwendbar sind. Die Scheiben P und A (Fig. ι und 2) können nun auf supportartigem Unterbau beweglich oder je nach ■ Belieben in waagrechter Ebene unbeweglich angeordnet sein. Doch mufs auch den bei dieser Ausführungsform zur Anwendung kommenden Schleifsteinen U und W eine Beweglichkeit in waagrechter Ebene verliehen werden, die auf supportartigem Unterbau in rechtwinkliger und paralleler Richtung zur Schleifsteinachse stattfinden kann.Also Fig. 4 is a section of the disc A with planed grooves for the grinding forms B (see. Fig. 1 of the main patent), but these grooves are here in something different, and in such an arrangement as they are attached to Disc P (Fig. 1) are applicable. The disks P and A (Fig. 1 and 2) can now be movably arranged on a support-like substructure or, depending on your needs, ■ be immovable in a horizontal plane. However, the grinding stones U and W used in this embodiment must also be given a mobility in a horizontal plane, which can take place on a support-like substructure in a right-angled and parallel direction to the grinding stone axis.

Die Scheibe A (Fig. 2) kann auch einseitig benutzt werden, d. h. es kann etwa die eine Mantelfläche H zum Schleifen benutzt werden, während die andere Mantelfläche S1 nicht benutzt wird.The disk A (FIG. 2) can also be used on one side, that is to say, for example, one lateral surface H can be used for grinding, while the other lateral surface S 1 is not used.

Bei Anwendung des Patentes 94967 hat sich die Nothwendigkeit gezeigt, zum Schleifen bestimmter Gegenstände, wie z. B. der nach Fig. 5 und 6 geformten Messer, die in den Fig. ι und 2 dargestellten Scheiben P und A zu benutzen. Beim Schleifen spitzer Messerklingen (nach Fig. 5) werden diese so aufgespannt, dafs ihre Spitzen nach der Scheibenachse zu gerichtet sind. Hierdurch wird bei dem Schleifen an der Spitze der Klinge eine stärker gewölbte Kreisfläche erzielt als an dem breiten Theil derselben, und aufserdem ist esWhen applying the patent 94967, the need has shown for grinding certain objects, such as. B. the knife shaped according to Fig. 5 and 6, the disks P and A shown in Figs. Ι and 2 to use. When sharpening sharp knife blades (according to Fig. 5) these are stretched so that their tips are directed towards the disc axis. In this way, when sharpening the tip of the blade, a more curved circular surface is obtained than on the broader part of the same, and it is also

besonders bei Scheibe A möglich, die Befestigungszwingen (welche die Klingen an ihren Angeln packen) von den Seiten der Trommel an ihre gröfste Oberfläche zu verlegen. Durch eine derartige Anordnung der zur Befestigung dienenden Theile sind diese den für die Bedienungsmannschaft gefährlichen Schlitzen zwischen Scheibe und Schlitten entrückt und zwischen den beiden Schleifsteinen U U angebracht. Especially with disc A, it is possible to move the fastening clamps (which grip the blades by their hinges) from the sides of the drum to their largest surface. Such an arrangement of the parts used for fastening means that these are removed from the slits between disk and slide, which are dangerous for the operating team, and are attached between the two grindstones UU.

Beim Schleifen der Messerklingen (Fig. 6) ist es allerdings nöthig, dafs die Klingenangeln nach der Scheibenachse zu gerichtet sind; da aber die Angeln nicht parallel mit der Achse stehen, so reichen sie doch nicht sehr weit in den freien Raum hinein, während die stärkere Wölbung der schmäleren Klingenstelle auch hierbei zum Vortheil gereicht.When sharpening the knife blades (Fig. 6) it is of course necessary that the blade tang are directed towards the disc axis; but since the hinges are not parallel to the axis, they are not enough very far into the free space, while the stronger curvature of the narrower blade point also here to the advantage.
