Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet eine Zange, welche zum Anholen von Holzstämmen, Steinen, Schienen und dergl. dient und eine sichere Greifwirkung gewährleistet. Von den bekannten Anholzatigen unterscheidet sich der Erfindungsgegenstand durch die doppelte Beeinflussung der Greifhaken, indem von dem einen Angriffspunkt aus mittels Gelenkhebel durch Druck und Zug zu gleicher Zeit auf ίο die Greiferarme gewirkt wird. Diese Greifwirkung ermöglicht auch das Anholen von Gegenständen geringeren Gewichts, z. B. von Baumstämmen geringen Durchmessers.The subject of the invention is a pair of pliers, which are used to fetch logs, stones, rails and the like and ensure a secure gripping effect. The subject of the invention differs from the known Anholzatigen by the double influence on the gripping hooks, in that the gripper arms are acted upon from one point of application by means of articulated levers by pushing and pulling at the same time. This gripping effect also enables objects of lighter weight to be picked up, e.g. B. of tree trunks of small diameter.

Eine Ausführungsform des Erfindungsgegenstandes ist auf der Zeichnung dargestellt, und zwar zeigt:An embodiment of the subject matter of the invention is shown in the drawing, namely shows:

Fig. ι eine Vorderansicht der Zange und Fig. 2 eine Seitenansicht derselben.Fig. Ι a front view of the pliers and Fig. 2 is a side view of the same.

Der Griff α ist drehbar mit einem"Tragstück b verbunden, an dem die Arme g, h und c, d angelenkt sind, deren Enden mit den Greifern e, f gelenkig verbunden sind. Eine Stange i ist einerseits um den Drehzapfen der Arme/, g drehbar und anderseits mit einem Schlitz / im Drehzapfen der Arme e, h verschiebbar und mittels Flügelmutter k feststellbar angebracht und dient zur Feststellung des Zangenausschlags.The handle α is rotatably connected to a "support piece b , to which the arms g, h and c, d are articulated, the ends of which are articulated to the grippers e, f . A rod i is on the one hand around the pivot of the arms /, g rotatable and on the other hand mounted with a slot / in the pivot of the arms e, h displaceable and lockable by means of wing nuts k and is used to determine the deflection of the pliers.

Je nach Art des zu greifenden Gegenstandes ist die Zangenklaue entsprechend ausgeführt. Während sie für Holz hakenförmig umgebogen oder mit Zahnflächen versehen ist, wird sie z. B. zum Greifen von Schienen flach gestaltet sein. Der zu greifende Gegenstand wird nach Überstreifen der Zange durch Anzug des Griffes α gefaßt, und zwar wird der Griff durch die doppelte Beeinflussung der Greiferarme ein besonders fester.Depending on the type of object to be gripped, the pincer claw is designed accordingly. While it is bent like a hook for wood or provided with tooth surfaces, it is z. B. be designed flat for gripping rails. The object to be gripped is grasped after slipping over the pliers by tightening the handle α , and the handle becomes particularly firm due to the double influence of the gripper arms.

Claims (1)

Patent-Anspruch:Patent claim: Anholzange, dadurch gekennzeichnet, daß die Greiferarme mittels zweier Gelenkhebelpaare derart am Tragstück angelenkt sind, daß die Greiferarme von dem einen Gelenkpaare, wie bekannt, durch Zug und von dem anderen durch Druck in die Greifstellung gebracht werden.Anholzange, characterized in that the gripper arms by means of two pairs of articulated levers are articulated on the support piece in such a way that the gripper arms of the one pair of joints, as known, by train and be brought into the gripping position by pressure from the other.
