KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Am Umfang muldenförmige Schleifscheiben großer Abmessungen, wie solche zum Schleifen der Spitzen von Nadeln, Stiften u. dgl. Verwendung finden, sind durch die bei ihrer Schwere und großen Umdrehungsgeschwindig-. keit sich ergebende große Zentrifugalkraft der Gefahr des Zerspringens ausgesetzt.On the circumference, trough-shaped grinding wheels of large dimensions, such as those for grinding the tips of needles, pins and the like. Use are by their Heavy and high speed of rotation. the resulting large centrifugal force of the Risk of shattering exposed.

Man hat daher bereits die Schleifvorrichtung aus zwei nebeneinanderliegenden ScheibenYou therefore already have the grinding device made up of two adjacent disks

ίο hergestellt, die mit einem Zwischenraum auf gesonderten Wellen befestigt waren. Der Zwischenraum war deswegen vorgesehen, weil .der mittlere Teil der Nadeln beim Anschärfen der Spitzen nicht bearbeitet werden soll.ίο made that with a space in between separate shafts were attached. The space was provided because .the middle part of the needles should not be processed when sharpening the tips.

Um nun den bei Anwendung geteilter Scheiben unvermeidlichen doppelten Antrieb zu vermeiden und trotzdem genügende Sicher- · heit gegen Zerspringen der Scheibe zu gewinnen, wird nach der Erfindung der Zwischen-Now about the inevitable double drive when using split discs to avoid and still gain sufficient security against shattering the pane, is according to the invention of the intermediate

ao raum zwischen den beiden Schleifkörpern durch einen besonderen Ringkörper ausgefüllt und die Teile durch eine Spannvorrichtung zu einem geschlossenen Scheibenkörper vereinigt. ao space between the two grinding tools is filled by a special ring body and the parts are combined into a closed disk body by a clamping device.

Die Zeichnung zeigt eine derartige Scheibe in Fig. ι im Querschnitt, in Fig. 2 in Vorderansicht, in Fig. 3 in Stirnansicht. Die Scheibe besieht aus den Schleifscheiben α und b und einem besonderen Ringkörper c dazwischen für den mittleren nicht zu schleifenden Teil der' Nadel. Die Teile a, b und c sind durch Schraubenbolzen zu einem geschlossenen Körper verbunden. Der Ringkörper c kann auch einen kleineren Durchmesser als die Schleifscheiben haben. ' Es können anstatt zwei auch mehrere Schleifscheiben in Frage kommen.The drawing shows such a disk in FIG. 1 in cross section, in FIG. 2 in front view, in FIG. 3 in front view. The disk consists of the grinding disks α and b and a special ring body c between them for the central part of the needle that is not to be ground. The parts a, b and c are connected by screw bolts to form a closed body. The ring body c can also have a smaller diameter than the grinding wheels. '' Instead of two, several grinding wheels can also be used.
