Description
Vorrichtung zum Abziehen und Schleifen dünner Rasierhobelklingen gleichzeitig an zwei Schneidenflächen einer und derselben Klingenseite. Die Erfindung betrifft solche Vorrichtungen zum Abziehen und Schleifen dünner Rasierhobelklingen, bei welchen das Abziehen und Schleifen gleichzeitig an zwei Schneidflächen einer und derselben Klingenseite erfolgt und der Klingenträger während des Schleifens vermittels eines Kurvengetriebes achsial hin und her bewegt wird.Device for honing and sharpening thin safety razor blades at the same time on two cutting surfaces on one and the same blade side. The invention relates to such devices for sharpening and sharpening thin razor blades, which honing and grinding at the same time on two cutting surfaces one and the same Blade side takes place and the blade carrier during grinding by means of a Cam gear is moved axially back and forth.
Der Zweck der7Erfmdung, ist, bei solchen Abzieh- und Schleifvorrichtungen die achsiale Hin- und Herbewegung des Klingenträgers vermittels eines Kurvengetriebes auf möglichst einfache und billige Weise sowie derart herzustellen, daß eine gedrängte und handliche Bauart gewahrt bleibt.The purpose of the invention is, with such honing and grinding devices the axial back and forth movement of the blade carrier by means of a cam gear in the simplest and cheapest way possible and in such a way that a compact and handy design is preserved.
Hierzu wird erfindungsgemäß die Welle des achsial verschiebbaren Klingenträgers zwangläufig mit einer am Gestell befestigten Feder verbunden, die den Klingenhalter in der einen Richtung zu verschieben sucht, während die ihr zugekehrte Stirnfläche der einen Schleif-oder Abziehwalze eine als Steuerfläche dienende Schrägfläche erhält, an der die Blattfeder mittels eines Gleitstiftes anliegt, so daß die ansteigende Schrägfläche die Feder entgegen ihrer Federwirkung nach außen drückt und damit den Klingenhalter in der anderen Richtung verschiebt.According to the invention, the shaft of the axially displaceable blade carrier is used for this purpose necessarily connected to a spring attached to the frame that holds the blade holder seeks to move in one direction, while the face facing it which has an inclined surface serving as a control surface for a grinding or peeling roller, on which the leaf spring rests by means of a sliding pin, so that the rising Inclined surface pushes the spring against its spring action outwards and thus the Blade holder moves in the other direction.
In der Zeichnung ist eine solche beispielsweise mit zwei Rollen versehene Vorrichtung zum Abziehen und Schleifen dünner Rasierhobelklingen durch Fig. x und 3 in einer Vorderansicht und- durch Fig. 2 in einer Seitenansicht dargestellt, wobei Fig. i den Klingenhalter nach rechts und die Fig. 3 den Klingenhalter nach links verschoben zeigt.In the drawing, one is provided with two rollers, for example Device for honing and grinding thin razor blades by Fig. X and 3 shown in a front view and by FIG. 2 in a side view, wherein Fig. I the blade holder to the right and Fig. 3 the blade holder to the left shows shifted.
Danach ist die Welle h des achsial in dem Apparategestell hin und her verschiebbaren Klingenträgers auf der einen Gestellseite zwangläufig mit einer an dem Apparategestell befestigten Blattfeder g verbunden. Diese besitzt einen nach einwärts gerichteten Stift i, der an einer ihm zugekehrten, an der Stirnfläche k der Schleif- und Abziehwalze c sitzenden Schrägfläche läuft. Werden nun die durch ein Stirnradgetriebe d, e miteinander verbundenen Schleif- und Abziehwalzen z. B. mittels einer Handkurbel in Umdrehung versetzt, so gleitet der Stift i der Feder g an der Schrägfläche der Schleif- und Abziehwalze entlang. Dadurch- wird durch die ansteigende Schrägfläche die Feder g entgegen ihrer Federwirkung nach außen gedrückt und damit der Klingenträger nach rechts in die aus Fig. i ersichtliche Stellung gezogen. Ist die ansteigende Schrägfläche an dem Stift i vorbeigegangen, so kommt die Feder g wieder zur Wirkung und schiebt nunmehr den Klingenträger nach links in die in Fig. 3 ersichtliche Stellung. Dieses Spiel wiederholt sich bei jeder einmaligen Umdrehung der Schleif- und Abziehwalzen.After that, the shaft h of the axially in the apparatus frame is back and forth ago displaceable blade carrier on one side of the frame necessarily with a attached to the apparatus frame leaf spring g connected. This owns one after inwardly directed pin i, which is on one facing it, on the end face k the sanding and dressing roller c seated inclined surface runs. Are now through a spur gear d, e interconnected grinding and peeling rollers z. B. set in rotation by means of a hand crank, the pin i of the spring slides g along the inclined surface of the sanding and peeling roller. This is through the rising inclined surface pushes the spring g against its spring action towards the outside pressed and thus the blade carrier to the right in the one shown in FIG Position drawn. If the inclined surface has passed the pin i, so the spring g comes into effect again and now pushes the blade carrier left in the position shown in FIG. This game repeats itself for everyone single rotation of the grinding and peeling rollers.
