KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet einThe subject of the invention is a

Rohrschlüssel mit schwingbarer Backe und herausklappbarer Stellspindel. Von bekannten Rohrschlüsseln dieser Art unterscheidet sich der Erfindungsgegenstand dadurch, daß der Klappbolzen für die Spindel auch der Schwingbolzen der Greifbacke ist, wodurch die Bauart des Schlüssels vereinfacht wird.Tubular wrench with swiveling jaw and fold-out adjusting spindle. Of known Pipe wrenches of this type differs from the subject matter of the invention in that the The hinge pin for the spindle is also the swing pin of the gripper jaw, which simplifies the design of the key.

Auf der Zeichnung, welche eine beispielsweise Ausführungsform veranschaulicht, ist die feste Backe in Ansicht, die verstellbare im Schnitt dargestellt.On the drawing which illustrates an example embodiment is the fixed jaw in view, the adjustable jaw shown in section.

Auf dem Schaft 2 der festen Backe ist die verschiebbare Backe 4 mit den Öffnun-The movable jaw 4 with the openings is on the shaft 2 of the fixed jaw.

*5 £en 5 un(i 6 aufgesteckt. Die hintere Wandfläche der Öffnung" 6 ist derart gekrümmt, " daß sie nur in der Mitte an dem Schaft anliegt, während oben und unten ein Spielraum vorhanden ist. Demzufolge kann das obere Ende der Backe 4 eine durch die Weite der Öffnung 5 begrenzte Schwingung um den Bolzen 16 ausführen. Durch den Bolzen 16 wird nun gemäß der Erfindung auch die Spindel 13 gehalten, die durch eine gegen einen Ansatz 15 sich stützende Feder 14 in die Zahnung des Schaftes 2 gedrückt wird, und so, wie bekannt, · die verstellbare Backe in ihrer Lage sichert. Der Ansatz 15 sitzt an einem besonderen, die Spindel drehbar haltenden Teile 17, der mit so viel Spielraum gelagert ist, daß er ein Herausklappen der Spindel aus der Zahnung des Schaftes zuläßt. * 5 £ en 5 un ( i 6 attached. The rear wall surface of the opening "6 is curved in such a way" that it rests against the shaft only in the middle, while there is clearance at the top and bottom. As a result, the upper end of the jaw 4 execute an oscillation around the bolt 16 limited by the width of the opening 5. The spindle 13 is now also held by the bolt 16 according to the invention and is pressed into the teeth of the shaft 2 by a spring 14 supporting itself against a shoulder 15 The extension 15 is seated on a special part 17 which rotatably supports the spindle and which is mounted with so much clearance that it prevents the spindle from folding out of the teeth of the shaft allows.

Zum ungefähren Einstellen des Schlüssels wird die Spindel herausgeklappt und die Backe verschoben, worauf nach Loslassen der Spindel das genaue Einstellen durch Drehen der Spindel erfolgt. Auf der Stirnseite der verstellbaren Backe ist, wie bekannt, eine verschiebbare Greifbacke 9 angeordnet, welche mit ihrer gekrümmten unteren Fläche auf dem bogenförmigen Sitz 10 geführt ist. Auf diesem Sitz wird die Greifbacke durch einen Stift 11 gehalten, welcher durch den gekrümmten Schlitz 12 der Backe hindurchgreift. For approximate setting of the key, the spindle is folded out and the Jaw moved, whereupon the exact setting is made by turning the spindle after releasing the spindle. On the front the adjustable jaw is, as known, a displaceable gripping jaw 9 is arranged, which is guided with its curved lower surface on the arcuate seat 10. On this seat, the gripping jaw is held by a pin 11, which by the curved slot 12 of the jaw engages therethrough.
