Die nachstehend beschriebene und in der Zeichnung dargestellte Erfindung behandelt eine Flachzange für Feinmechaniker, wobei an den Flachzangenbacken auswechselbare Futter angebracht sind, zum Zweck, das Material und die Form des Futters den zu bearbeitenden Gegenständen anzupassen. Es ist ein bekannter Uebelstand, dafs beim Bearbeiten der Kronenräder durch das Einspannen Beschädigungen aller Art vorkamen. Die bekannten, aus Holz hergestellten Feilkloben und Kronenhalter erfüllen nicht in allen Fällen ihren Zweck. Die aus Holz hergestellten Feilkloben waren z. B. sehr leicht dem Verschleifs unterworfen und die Gegenstände drückten sich beim Bearbeiten des eingespannten Gegenstandes in das Holz ein, es entstanden hierdurch Vertiefungen, welche ein weiteres Einspannen von Gegenständen an derselben Stelle nicht zuliefsen. Weiter wurden die feinen Zähne durch das häufige Ein- und Ausspannen beschädigt. Diesen Uebelständen soll die vorliegende Zange abhelfen. Wie aus der Zeichnung ersichtlich, ist sie in Gestalt der bekannten Flachzangen hergestellt. Das Maul d der Zange wird beiderseits, wie aus Fig. 1 der Zeichnung ersichtlich ist, mit den auswechselbaren Futtern α und b versehen. In Fig. 2 der Zeichnung ist ein Futter dargestellt, welches verschiedene Ausfräsungen besitzt, welche den Zweck haben, ein besseres Halten der Kronenräder u. s. w. beim Bearbeiten mit der Feile und dergl. zu ermöglichen, und beim Einspannen verschieden grofser Gegenstände eine stets gleiche Entfernung der Schenkel zu erzielen, wodurch ein besseres Halten der Zange mit den eingespannten Gegenständen herbeigeführt wird. Ein weiterer Vortheil bei Benutzung der neuen Zange besteht darin, jederzeit den zu bearbeitenden Gegenstand in jeder beliebigen Lage vor Augen führen zu können, ohne dafs es nothwendig ist, den vielleicht in günstiger Lage eingespannten Gegenstand loslösen zu müssen, wodurch auch die Gefahr der Beschädigung der Kronenräder vermieden wird.The invention described below and shown in the drawing deals with flat-nosed pliers for precision mechanics, with replaceable chucks being attached to the flat-nosed jaws for the purpose of adapting the material and the shape of the chuck to the objects to be processed. It is a well-known disadvantage that damage of all kinds occurred when the face gears were machined by clamping. The known wooden blocks and crown holders do not serve their purpose in all cases. The filing blocks made of wood were z. B. very easily subjected to wear and tear and the objects were pressed into the wood when the clamped object was processed, resulting in depressions which did not allow further clamping of objects at the same point. Furthermore, the fine teeth were damaged by the frequent clamping and unclamping. The present pliers are intended to remedy these inconveniences. As can be seen from the drawing, it is made in the form of the known flat-nose pliers. The mouth d of the pliers is provided on both sides, as can be seen from Fig. 1 of the drawing, with the interchangeable chucks α and b . In Fig. 2 of the drawing a chuck is shown, which has different millings, the purpose of which is to enable a better holding of the crown gears, etc. when working with a file and the like, and when clamping objects of different sizes an always equal distance of the legs to achieve, whereby a better hold of the pliers with the clamped objects is brought about. Another advantage of using the new pliers is to be able to show the object to be worked on in any position at any time without having to loosen the object, which may be clamped in a favorable position, which also increases the risk of damage to the Crown gears is avoided.
