KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Diese Rohrzange, welche zu denen mit Selbstspannung gehört, bei denen die Klauen scheerenartig das Rohr umfassen und eine Einstellvorrichtung besitzen, mit der es möglich ist, die Zange den verschiedensten Rohrweiten bequem anpassen zu können, zeichnet sich durch die eigentümliche Ausbildung dieser Einstellvorrichtung aus, indem diese hier als Druckhebel ausgebildet ist, welcher zur Erreichung einer veränderlichen Klauenöffnung in ihrer Länge verstellt werden kann.This pipe wrench, which is one of those with self-tensioning, where the claws are like scissors include the tube and have an adjustment device with which it is possible, the The ability to easily adapt the pliers to a wide variety of pipe widths is characterized by the peculiar design of this adjustment device by using this here as a pressure lever is designed, which to achieve a variable claw opening in its length can be adjusted.

Auf der Zeichnung ist eine derartige Zange in einem Ausführungsbeispiel dargestellt, und zwar zeigtIn the drawing, such a pair of pliers is shown in one embodiment, and although shows

Fig. ι und 2 die Zange in zwei verschiedenen Stellungen einer Spannweite,Fig. Ι and 2 the pliers in two different positions of a span,

Fig. 3 eine Seitenansicht zu Fig. 2,FIG. 3 shows a side view of FIG. 2,

Fig. 4 eine Einstellung der Zange für eine andere Spannweite,4 shows an adjustment of the pliers for a different span,

Fig. 5 eine Einzelheit.Fig. 5 shows a detail.

Die zum Umfassen des Rohres dienenden Klauen α b sind bei c an einander gelenkt und die Klaue α mit dem als Handhabe dienenden Spannhebel d bei e gelenkig verbunden. Die andere Klaue b ist in einer als Druckhebel wirkenden Lehre/ verstellbar, welche ihrerseits verschränkt zur Klaue α an dem Schaft d bei h drehbar ist. The claws α b serving to embrace the pipe are articulated to one another at c and the claw α is articulated to the clamping lever d serving as a handle at e. The other claw b is adjustable in a gauge / acting as a pressure lever, which in turn can be rotated crossed to the claw α on the shaft d at h.

Die Einstellung geschieht mit Hülfe einer Schraube i (Fig. 5), die mit ihrem prismatischen Theil k entweder so gestellt werden kann, dafs man sie durch die Schlitze / der Lehre / hindurchbringen oder sie in den Aussparungen m so querstellen kann, dafs sie an einer Verschiebung in der Lehre gehindert ist. Da sich die Klaue b mit dieser Schraube in der Lehre führt, so kann man auf diese Weise die Klauenöffnung erweitern bezw. verengen.The adjustment is made with the aid of a screw i (Fig. 5), the prismatic part k of which can either be set in such a way that it can be brought through the slots / the jig / or it can be placed in the recesses m in such a way that it is at a shift in teaching is prevented. Since the claw b leads with this screw in the teaching, you can expand the claw opening BEZW in this way. narrow.

Es wird also durch Verstellen der einen Klaue mittels der Lehre / eine grobe Anpassung an die verschiedensten Rohrweiten erzielt, während die Festspannung der Klauen am Rohr durch Verdrehen des Schaftes d erfolgt, indem hier die Lehre/ als Druckhebel wirkt.It is thus achieved by adjusting one claw by means of the gauge / a rough adaptation to the most varied pipe widths, while the clamping of the claws on the pipe takes place by turning the shaft d , in that the gauge / acts as a pressure lever.

Die Fig. 1 und 2 zeigen die Stellung der Zange beim Entspannen und Festspannen für eine Rohrweite, während Fig. 4 die Zange für eine andere, engere Rohrweite in entspannter Lage eingestellt veranschaulicht.1 and 2 show the position of the pliers when relaxing and tightening for a pipe width, while Fig. 4 shows the pliers for another, narrower pipe width in relaxed Location set illustrates.

Die Führung und Feststellung der Klaue b am Zwischenglied/könnte auch mittels Schlitten, Keil, Feder oder auf andere bekannte Weise erfolgen.The guiding and fixing of the claw b on the intermediate link / could also take place by means of a slide, wedge, spring or in another known manner.

Es empfiehlt sich, die Lehre/ mit einer Scala zu versehen, so dafs bei richtiger Einstellung der Schraube das Rohr nebst Muffe sich sofort der Zange anpafst, während gleichzeitig der Druckhebel in einer solchen Stellung steht, dafs er eine bequeme Handhabung gestattet. It is advisable to provide the gauge / with a scale so that it is correctly adjusted the screw the pipe and socket immediately adapts to the pliers, while at the same time the pressure lever is in such a position that it allows comfortable handling.
