Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bis jetzt findet das Ausschleifen enger Schlitze nur selten statt, da dünne Schleifscheiben, die hierzu benutzt werden müssen, zu leicht zerbrechen, und die Stücke beim Fortfliegen den Arbeiter verletzen.Up until now, the grinding out of narrow slots has only rarely taken place because of the thin grinding wheels that must be used for this purpose, break too easily, and the pieces when they fly away Injure workers.

Diesen Gefahren und anderen Uebelständen wird durch den Gegenstand der Erfindung dadurch vorgebeugt, dafs die zu dem erwähnten Zwecke bestimmten dünnen Schleifscheiben aus einer Verbindung von Blech- oder Celluloidplatten mit Schmirgelmasse hergestellt werden. Die Platten sind, wie Fig. 1 zeigt, mit vielen Löchern versehen, in welchen sich die umgelegte Schleifmasse nach ihrer Erhärtung zu halten vermag.These dangers and other evils are addressed by the subject matter of the invention This prevents the thin grinding wheels intended for the purpose mentioned from being damaged a connection of sheet metal or celluloid plates with emery. The plates are, as Fig. 1 shows, provided with many holes in which the folded Abrasive compound is able to hold after it has hardened.

Fig. 2 zeigt einen Schnitt der Fig. 1, aus dem zu ersehen ist, dafs die Schleifmasse nur an den Stellen an die Blechscheibe aufgetragen wird, wo sie zur Benutzung gelangen soll. Der mittlere Theil der Scheibe bleibt in der Regel frei von der erwähnten Schmirgelmasse, während der Rand, der mit ,der nöthigen Anzahl von Löchern in zweckmäfsiger Gröfse und Form versehen ist, von der Schleifmasse ringförmig und in beliebiger Querschnittsform umschlossen ist.FIG. 2 shows a section of FIG. 1, from which it can be seen that the grinding compound is only applied to the sheet metal disc in the places where it is used target. The middle part of the disc usually remains free of the emery compound mentioned, while the edge, the one with, the necessary number of holes in an appropriate size and shape is provided, of the grinding compound ring-shaped and in any cross-sectional shape is enclosed.

Ist die unter solchen Verhältnissen aufgetragene Schmirgelmasse gut erhärtet, so erscheint jede Gefahr beim Schleifen ausgeschlossen, und wenn selbst durch unvorsichtige Behandlung, wie z. B. bei zu starkem seitlichen Druck, die Schleifscheibe stellenweise rissig wird, so vermag dies doch keinen Schaden anzurichten.If the emery compound applied under such conditions has hardened well, then appears any danger during grinding is excluded, and even if carelessly handled, such as B. if the side is too strong Pressure, the grinding wheel cracks in places, this is not capable of this To cause harm.
