PATENTAMT.PATENT OFFICE.
Die im Hauptpatent beschriebene Erfindung bezieht sich auf die-Bewegung der Kübel mit Hilfe von Schwinghebeln, . wodurch bei günstigster Grabkurve erreicht wird, daß derThe invention described in the main patent relates to the movement of the buckets Help of rocker arms,. whereby it is achieved with the most favorable digging curve that the
Weg des Flaschenzugs sich gegenüber Greifern mit schließenden Schaufeln nicht vergrößert. Die im Hauptpatent beschriebene Anordnung besitzt aber hoch den Nachteil,« daß der mittlere Teil des von den Kübeln zusammengescharrten Gutes beint Anheben des Greifers ■ infolge des vorhandenen Abstandes zwischen den 'Schneidkanten der Kübel liegen bleibt.The path of the pulley block does not increase compared to grippers with closing shovels. The arrangement described in the main patent has the major disadvantage that the middle Part of the material scraped together by the buckets is due to the lifting of the gripper ■ remains due to the existing distance between the 'cutting edges of the pail.
Die vorliegende Erfindung bezweckt, diesen mittleren Teil des zusammengescharrten Gutes mit aufzunehmen, ohne daß dadurch der Grundsatz des Hauptpatentes, einen solchen .Abstand zwischen den Schneidkanten der Kübel zu lassen, daß keine Zertrümmerung von Material notwendig ist, verletzt wird. Erreicht wird dieser Erfolg dadurch, daß der einen Schaufel gegenüber der andern in der Schließbewegung eine Voreilung gegeben wird, so - daß in der Endstellung die Schneidkanten der Kübel nicht wie beim Hauptpatent nebeneinander, sondern unter-.bzw. übereinander lie- gen. Es genügt,- wenn die Schneidkanten un- -> gefähr senkrecht übereinander zu stehen kommen. Man kann jedoch, um einen· besseren Abschluß zu erreichen, wie auf der Zeichnung dargestellt ist, eine Art Überlappung eintreten lassen. Bei dieser Anordnung schaufelt gewissermaßen die voreilende Schaufel der nacheilenden das Gut zu und es wird das ganze zusammengescharrte Gut aufgenommen, da in der Schließstellung zwischen den beide'n Kübein nichts herunterfallen kann. Trotzdem ' tritt keine Klemmung oder Zertrümmerung von Stücken des Gutes zwischen den Kübelschneiden, ein. ' The present invention aims at this middle part of the scraped up goods to include without thereby the principle of the main patent, such .Abstand to leave between the cutting edges of the pail that no shattering of material is necessary, is injured. This success is achieved by the fact that the one Blade is given a lead over the other in the closing movement, so - That in the end position the cutting edges of the bucket not next to each other as in the main patent, but under-.bzw. one on top of the other gen. It is sufficient - if the cutting edges un- -> danger of standing vertically on top of each other. One can, however, to get a · better To achieve completion, as shown in the drawing, a kind of overlap occur permit. With this arrangement it is, so to speak, shoveling the leading shovel to the lagging the good and it becomes the whole Scruffed together Well received, because in the closed position between the two kebabs nothing can fall down. Nevertheless, there is no jamming or shattering of pieces of the goods between the bucket cutting edges. '
