PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Vorrichtung zum Zerstören und Zerkleinern von Schriftstücken, Akten, Zeichnungen u. dgl. mit Hilfe einer Anzahl scherenartig zusammenwirkender Messer, von denen die einen gerade, die anderen wiegemesserartig gekrümmt sind.The invention relates to a device for destroying and shredding documents, Files, drawings and the like with the help of a number of knives that work together like scissors, some of which are straight, others are curved like a knife.
Das Neue ·> besteht darin, daß die gekrümmten Messer in der Nähe ihres Drehpunktes eine Einkerbung besitzen, die beim. Zerstören und Zerkleinern dicker, starker Papierstücke diese gerade dann festhält und am Ausweichen verhindert, wenn diese Gefahr am größten ist, nämlich beim Beginn des Zerschneiden.The new ·> is that the curved Knives have a notch near their pivot point that Destroy and shredding thick, strong pieces of paper just then holding them in place and dodging them prevented when this risk is greatest, namely at the start of cutting.
In der Zeichnung ist die Erfindung darge-1S stellt; es zeigen Fig. ι einen Schnitt nach der Linie A-B der Fig. 2, und Fig. 2 eine Ansicht in der Pfeilrichtung C der Fig. i.In the drawing the invention is ones shown, provides 1 S; FIG. 1 shows a section along the line AB in FIG. 2, and FIG. 2 shows a view in the direction of the arrow C in FIG.
Die unteren wagerecht angeordneten Messer α wirken mit den wiegemesserartig ge- *° krümmten Messern b in bekannter Weise scherenartig zusammen. Die Messer α sind mit dem gegebenenfalls zur Aufnahme der Papierspäne dienenden Untergestell d mittels der Achsen e und f fest verbunden, während die Messer b einerseits an der Achse f und andererseits an . der Achse g des Hebelgriffes h befestigt sind.The lower horizontally arranged knives α interact in a known manner like scissors with the knives b, which are curved in the manner of a chopping knife. The knives α are firmly connected to the subframe d, which may be used to receive the paper chips, by means of the axes e and f , while the knives b are on the one hand on the axis f and on the other hand. the axis g of the lever handle h are attached.
Damit beim Zerstören und Zerkleinern dicker, starker Papierstücke diese gerade dann festgehalten werden und nicht ausweichen, wenn diese Gefahr am größten ist, nämlich beim Beginn des Zerstörens, sind gemäß der Erfindung die Messer b in der Nähe ihres Drehpunktes (Achse f) sämtlich mit einer Einkerbung c versehen.So that when destroying and shredding thick, strong pieces of paper they are held and not evade when this danger is greatest, namely at the beginning of the destruction, according to the invention, the knives b in the vicinity of their pivot point (axis f) are all with a Notch c provided.
Die Wirkungsweise der Vorrichtung ist folgende: Nachdem das zu zerstörende Akten-, stück ο. dgl. über die nebeneinander liegenden '. Messer α gelegt ist, bewegt man den Hebelgriff h nach unten. Beim Zerstören und Zerkleinern dicker, starker Stücke werden diese von der Einkerbung c der gekrümmten Messer b gerade beim Beginn des Zerstörungsvorganges festgehalten, weil dann die Gefahr des Ausweichens dieser Stücke am größten ist.The mode of operation of the device is as follows: After the file to be destroyed, ο. Like. About the adjacent '. Knife α is placed, the lever handle h is moved downwards. When destroying and chopping thick, strong pieces, they are held in place by the notch c of the curved knife b at the beginning of the destruction process, because then the risk of these pieces escaping is greatest.
