Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Da das Abschrägen der Kanten an metallenen Schlüssel- und anderen Schildern von Hand viel Zeit beansprucht, hat man bereits versucht, mittels einer Schmirgelscheibe die eingespannten Schilder abzuschrägen. Dieses Arbeitsverfahren kam aber bald wieder außer Gebrauch, weil ein genaues geradliniges Abschrägen der Kanten an den Schildern nicht möglich war. Die Schilder sind aus verhältnismäßig dünnem Blech und kommen beim Bearbeiten durch die Schmirgelscheibe in Schwingung, so daß als Begrenzungslinie für die Abschrägung sich keine glatte, sondern eine unregelmäßige Wellenlinie ergibt.Since the bevelling of the edges on metal key tags and other signs from It takes a lot of time to use an emery disk to try to remove the bevel clamped signs. This working method soon came out of the blue Use because an exact straight beveling of the edges on the signs is not possible was possible. The signs are made of relatively thin sheet metal and come through the sanding disk when working in oscillation, so that the boundary line for the bevel is not a smooth one, but a results in an irregular wavy line.

Die auf der Zeichnung dargestellte Vorrichtung beseitigt den vorerwähnten Übelstand, ermöglicht also die Herstellung einer genau geradlinig begrenzten Abschrägung.The device shown in the drawing eliminates the aforementioned inconvenience, thus enables the production of a precisely linearly delimited bevel.

Fig. ι zeigt die Vorrichtung von der Seite gesehen, Fig. 2 von oben und'Fig. 3 in der Rückansicht; Fig. 4 zeigt ein fertiges Schlüsselblech in Ansicht und Fig. 5 im Schnitt. "Fig. 1 shows the device seen from the side, Fig. 2 from above and'Fig. 3 in the rear view; Fig. 4 shows a finished key plate in view and Fig. 5 in Cut. "

Das glatte Abschrägen mittels Schmirgelscheibe α (Schleifstein ο. dgl.) wird dadurch erreicht, daß dem zu bearbeitenden Werkstück d dort, wo die Schmirgelscheibe angreift, nur eine ganz schmale Auflage geboten ist, während die. entfernt von der Schmirgelscheibe liegende Kante des Werkstückes in ihrer vollen Länge Auflage findet.The smooth chamfering by means of an emery wheel α (grindstone ο. Like.) Is achieved in that the workpiece to be machined d where the emery wheel engages, only a very narrow support is required, while the. the edge of the workpiece located away from the emery disk finds support in its full length.

Es ergeben sich also für das Werkstück gewissermaßen nur drei Auflagepunkte. Infolgedessen fällt jede Schwingung fort und das allmählich an der Schmirgelscheibe vorübergeführte Schlüsselschild ο. dgl. bekommt eine vollkommen geradlinig begrenzte Abschrägung. Um die Auflage an der zu bearbeitenden Stelle nur schmal zu gestalten, ist ein Fassonstück c angewendet, welches in der Mitte eine schmale, wagerechte Abflachung besitzt, nach außen aber dachförmig abfällt. Die Bearbeitung größerer oder kleinerer Werkstücke ist dadurch möglich, daß die dem hinteren Teil des letzteren zur Auflage dienende Platte e verstellbar angeordnet ist und mittels Klemmschraube befestigt werden kann. . .So there are, so to speak, only three support points for the workpiece. As a result, every oscillation disappears and the key plate gradually passed on the emery disk ο. Like. Gets a completely straight-line limited bevel. In order to make the support at the point to be machined only narrow, a shaped piece c is used, which has a narrow, horizontal flattening in the middle, but slopes downwards in the shape of a roof. The processing of larger or smaller workpieces is possible in that the plate e serving the rear part of the latter is adjustably arranged and can be fastened by means of a clamping screw. . .
