KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine schnellspannende Zange für runde und eckige Gegenstände, die bei einfacher Bauart schnelle Verstellbarkeit und sicheres Fassen ermöglicht. The subject of the invention is a quick-release pliers for round and angular objects, which, with a simple design, enables quick adjustability and secure gripping.
Die Zeichnung stellt die Zange in Fig. ι und 2 in zwei Ansichten dar.The drawing shows the pliers in Fig. Ι and 2 in two views.
Sie besteht im wesentlichen aus zwei gelenkig miteinander verbundenen Backen« und b, ίο von denen die erstere zum Handgriff ausgebildet ist. Die gelenkige Verbindung beider Backen geschieht durch Hebelpaare c, c und d, d, deren Drehzapfen e, e und f, f in der Backe α und in der Backe b vorgesehen sind, derart, daß die Hebel sich kreuzen und von ungleicher Länge sind. Zu diesem Zwecke ist das eine der übereinander gehenden Paare gekröpft. Einer der Hebel f ist verlängert und zu einer ' Druckplatte g ausgebildet; durch einen Fingerdruck hierauf wird die Maulweite verändert.It essentially consists of two hinged jaws and b, ίο of which the former is designed as a handle. The articulated connection of the two jaws is done by pairs of levers c, c and d, d, the pivot pins e, e and f, f of which are provided in the jaw α and in the jaw b , in such a way that the levers cross each other and are of unequal length. For this purpose, one of the superimposed pairs is cranked. One of the levers f is elongated and formed into a 'pressure plate g ; the mouth width is changed by pressing it with a finger.
Durch die eigenartige gelenkige Verbindung der beiden Backen wird bei passender Wahl der Hebellänge usw. und richtiger Formgebung der Arbeitsflächen der Backen erreicht, daß diese Arbeitsflächen in allen Stellungen eine mehr oder weniger parallele Lage zueinander haben.Due to the peculiar articulated connection of the two jaws, the right choice the lever length etc. and correct shaping of the working surfaces of the jaws, that these working surfaces have a more or less parallel position in all positions have to each other.
Beim Gebrauch ist es nur nötig, mittels eines Druckes auf die Platte g die Zange zum Anliegen an das Werkstück zu bringen; hat sie einmal gefaßt, so zieht sie sich beim Gebrauch von selbst fest.In use, it is only necessary to bring the pliers to rest on the workpiece by means of pressure on the plate g; once it has been grasped, it will tighten by itself when you use it.
Statt einer Zahnung der Arbeitsflächen der Backen a, b könnten auch Einschnitte darin vorgesehen werden, mit denen man Muttern übereck fassen kann.Instead of a toothing of the working surfaces of the jaws a, b , incisions could also be provided in them, with which one can grasp nuts across the corner.
