Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Zusatz - Erfindung betrifft eine Verbesserung und weitere Ausbildung des Gegenstandes des Hauptpatentes. Es soll diese verbesserte Vorrichtung an Stelle der im Haupt patent näher beschriebenen Doppelkralle verwendet werden.The present addition - invention relates to an improvement and further development of the Subject matter of the main patent. It is intended to use this improved device in place of the one in the main patent double claw described in more detail can be used.
Wie aus beiliegender Zeichnung (Fig. 1) ersichtlich, besteht die Vorrichtung aus einem Winkelstück a, welches im oberen Schenkel die Stellschraube b aufnimmt und ferner mit einem gabelartig geschlitzten Querstück c verbunden ist, welches sich mit seinen beiden Teilen an den Trägerflansch legt und bei Anziehen der Stellschraube b den Träger einklemmt. As can be seen from the accompanying drawing (Fig. 1), the device consists of an angle piece a, which receives the adjusting screw b in the upper leg and is also connected to a fork-like slotted crosspiece c, which attaches with its two parts to the carrier flange and at Tightening the set screw b clamps the carrier.
Im unteren Schenkel des Winkelstückes a befindet sich eine Durchlochung d, durch welche die abgepaßte Kette β läuft, in welche die Verbindungskette f eingehakt wird. Diese Kette führt wie bei der Einrichtung des Hauptpatentes zu den Greifbacken in der Mitte des Trägers.In the lower leg of the angle piece a there is a perforation d through which the matched chain β runs, into which the connecting chain f is hooked. As with the establishment of the main patent, this chain leads to the gripping jaws in the middle of the carrier.
Durch diese Anordnung wird beim Hochziehen der mit der Durchlochung d versehene Schenkel des Winkelstückes α gegen die Stirnseite des Trägerendes gedrückt und dadurch eine äußerst günstige Beanspruchung erzielt. Diese günstige Beanspruchung ermöglicht wieder Ersparnisse am Gewicht der Greifvorrich-, tung bei größter Betriebssicherheit und können daher bei kleineren Trägern, von denen gewöhnlich zwei zusammen hochgezogen werden, auch gleichzeitig zwei Greifer in der aus Fig. 2 veranschaulichten Weise angelegt werden.As a result of this arrangement, the leg of the angle piece α, which is provided with the perforation d, is pressed against the end face of the carrier end when it is pulled up, and an extremely favorable stress is achieved as a result. This favorable stress again enables savings in the weight of the gripping device with the greatest operational reliability and can therefore also be applied simultaneously to two grippers in the manner illustrated in FIG. 2 for smaller carriers, two of which are usually pulled up together.
Durch die Anbringung der Stellschraube b am oberen Schenkel des Winkelstückes α wird ein Lösen der Greifvorrichtung vom Träger auch bei wenig stramm angezogener Verbindungskette unmöglich gemacht.By attaching the adjusting screw b to the upper leg of the angle piece α , it is impossible to loosen the gripping device from the carrier even if the connecting chain is not tightened too tightly.
