Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bei Rohrzangen bekannt, die Abnutzung der Zangenschenkel durch Nachschärfen der Zahnung zu beseitigen und ein schärferes Anfassen des Rohres zu ermögliehen dadurch, daß die Zahnung nach Abnutzung ausgewechselt wird. Man hat auch schon bei Rohrzangen Zahnrollen als Greifflächen benutzt.It is known that pipe wrenches wear and tear on the legs of the pliers as a result of resharpening to eliminate the toothing and to enable a sharper grip on the pipe in that the toothing is replaced after wear. One also has Gear rollers have already been used as gripping surfaces in pipe wrenches.

In der Zeichnung ist eine Zahnrollenanordnung einer neuen Ausführungsform dargestellt.In the drawing, a toothed roller arrangement of a new embodiment is shown.

Der Zangenschenkel b wird in der Größe der Rollen m bogenförmig ausgefräst. Durch die Deckplatte R wird die Rolle seitlich festgehalten. Der Zapfen ο der Rolle, der in einer Führung 5 geht, hält die Rolle in ihrer Lage. Im Kopf des Zangenschenkels α sitzen zwei ebenso gelagerte und geführte Rollen.The pliers leg b is milled out in an arc shape to the size of the rollers m. The roll is held in place on the side by the cover plate R. The pin ο of the roller, which goes in a guide 5, holds the roller in its position. In the head of the pliers leg α, there are two equally supported and guided rollers.

Beim Zusammendrücken der Zangenschenkel und beim Fassen des Rohres drücken die Rollen α gleichzeitig gegen die Wandungen m der Ausfräsung, und es ist dadurch eine Umdrehung der Rollen ausgeschlossen.When the pliers legs are pressed together and the pipe is grasped, the rollers α simultaneously press against the walls m of the cutout, and a rotation of the rollers is thereby excluded.

Claims (1)

Patent-Anspruch:Patent claim: Rohrzange mit auswechselbaren Greifflächen in Form von Zahnrollen, die beim Zusammendrücken der Zangenschenkel beim Fassen des Rohres gegen eine Wandung der Zange gedrückt werden, dadurch ge-' kennzeichnet, daß die Wandung, gegen welche die Zahnrollen gedrückt werden, je eine kreisbogenförmige Höhlung bildet, die sich dem Umfang der Zahnrolle anschmiegt. Pipe wrench with exchangeable gripping surfaces in the form of toothed rollers that are used in Compression of the pliers legs when grasping the pipe are pressed against a wall of the pliers, thereby indicates that the wall against which the toothed rollers are pressed, each forms a circular arc-shaped cavity, which hugs the circumference of the toothed roller.
