KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Vorrichtung zum Erfassen und Heben ring- oder rahmenförmiger Werkstücke, insbesondere zum Aufstapeln von Drahtringen durch Spreizen in 5, das Werkstück eingeführter, mit einer Lasthebevorrichtung verbundener Arme.The invention relates to a device for grasping and lifting ring-shaped or frame-shaped Workpieces, in particular for stacking wire rings by spreading them in Fig. 5, the workpiece inserted with a load lifting device bandaged arms.

Die Erfindung besteht darin, daß diese Arme durch kniehebelartig wirkende Lenker unter sich und mit der LasthebevorrichtungThe invention consists in that these arms by toggle-like acting handlebars under themselves and with the load lifting device

ίο verbunden sind, so daß eine große Verstellungsmöglichkeit und ein großer Anpressungsdruck der Arme an das Werkstück erzielt wird.ίο are connected, so that a great adjustment option and a large contact pressure of the arms against the workpiece is achieved.

Diese Einrichtung dient dazu, die Arme α nach ihrer Einführung in das Werkstück durch Abwärtsbewegen der Muffe i in Anlage mit dem Werkstück zu bringen, bevor das Anheben erfolgt.a5 ker b spread apart and pressed against the workpiece in such a way that they take it with them. The upper ends of the arms α are also connected by chains h or the like to a sleeve i , which is connected by suitable tension members k to a four-cranked crankshaft m supported on the cross member f . This device is used to bring the arms α after their introduction into the workpiece by moving the sleeve i down into contact with the workpiece, before the lifting takes place.
