KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine besondere Ausführungsform jener bekannten Rohrzangen, bei denen die Aufgabe gelöst ist, mit einer Zange verschieden große Gegenstände, wie Rohre, Schrauben, Muttern u. dgl., sofort fassen zu können, ohne die Zange umstellen zu müssen.The invention relates to a particular embodiment of those known pipe wrenches, where the task is solved, with a pair of pliers different sized objects, such as Pipes, screws, nuts and the like can be grasped immediately without having to move the pliers to have to.
Bei der in der Zeichnung veranschaulichten Ausführungsform ist der verschiebbare Zangenschenkel b mit einem schrägen Führungsschlitz d versehen, in welchen ein Stift g des Schenkels α greift. Werden die beiden Schenkel auseinandergezogen, so daß der schräge Schlitz d parallel zum Schenkel α steht, so kann die Zange in jede Stellung gebracht werden. Der Schenkel α ist mit einer Verzahnung i versehen, in die, wie bei bekannten Zangen, eine Stützklinke k des verschiebbaren Schenkels so eingreift, daß beim Packen des Rohres eine Rollenbewegung entsteht. Beim Zusammendrücken der beiden Schenkel greift die Stützklinke in die Verzahnung des Schenkels α, beim Öffnen der Zange wird sie ausgehoben; sie ist hierzu mit einer Nase I versehen, welche durch die Feder f an die Wandung des Schenkels b gedrückt wird und beim Öffnen der Zange in dieser Stellung bleibt. Die Wirkung beim Zusammendrücken der beiden Schenkel ist infolge der Führung des Stiftes g in dem schrägen Führungsschlitz d und wegen des Stützklinkeneingriffs in die Verzahnung eine hebelartige, und es findet ein Nachschub des Schenkels b von 5 bis 8 mm statt, wodurch ein kräftiges Anfassen des Rohres gesichert ist. Der Druck lastet nicht allein auf der Klinke, wie bei bekannten Zangen, sondern verteilt sich auf die Klinke und den Stift g.In the embodiment illustrated in the drawing, the displaceable pliers leg b is provided with an inclined guide slot d, in which a pin g of the leg α engages. If the two legs are pulled apart so that the inclined slot d is parallel to the leg α , the pliers can be brought into any position. The leg α is provided with a toothing i , into which, as in known pliers, a support pawl k of the displaceable leg engages in such a way that a roller movement occurs when the pipe is packed. When the two legs are pressed together, the support pawl engages in the toothing of the leg α; when the pliers are opened, it is lifted out; for this purpose it is provided with a nose I which is pressed against the wall of the leg b by the spring f and remains in this position when the pliers are opened. The effect when the two legs are pressed together is lever-like due to the guidance of the pin g in the inclined guide slot d and due to the support pawl engagement in the toothing, and leg b is replenished by 5 to 8 mm, which means that the pipe is gripped vigorously is secured. The pressure is not only on the pawl, as is the case with known pliers, but is distributed over the pawl and the pin g.
