KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der in der Zeichnung dargestellte Apparat soll dazu dienen, die grofsen und kleinen Erdschollen, welche durch das Pflügen des Ackers entstehen, und die bis jetzt in unvollkommener Weise durch Schollenbrecher-Ringelwalzen oder Eggen nur zum Theil und nicht genügend zerkleinert wurden, vollständig zu zerstören, die darunter liegende Erde aufzulockern und das Land in den für die Saat vortheilhaftesten Zustand zu bringen.The device shown in the drawing should serve to remove the large and small clods of earth, which arise from plowing the field, and which so far have been imperfect By means of clod-breaking curling rollers or harrows only in part and not enough crushed, completely destroying, loosening and loosening the soil below to bring the land into the most favorable condition for the sowing.
Zu diesem Zwecke sind zwischen den festen Zahnreihen abc bewegliche Zahnsysteme d und e angeordnet, bei welchen die Zähne mittelst Zahnradübertragung, Kurbelwelle und Zugstangen von einem oder beiden der Laufräder aus in schwingende Bewegung gesetzt werden. Ebenso können aber auch sämmtliche Zahnreihen ab c d e eine hin- und hergehende Bewegung erhalten, oder es kann auch eine Reihe fest stehen und nur die übrigen beweglich sein.For this purpose, movable tooth systems d and e are arranged between the fixed rows of teeth abc , in which the teeth are set in oscillating motion by means of gear transmission, crankshaft and tie rods from one or both of the running wheels. Likewise, however, all rows of teeth from cde can also be given a back and forth movement, or one row can also be fixed and only the others can be moved.
Das ganze Zahnsystem ist in dem die Räder verbindenden Kasten durch Hebel auf- und niederzubewegen, um entweder beim Transport auf der Strafse ganz gehoben oder zum Betrieb auf dem Acker in beliebig passender Höhe eingestellt werden zu können.The whole tooth system is opened and closed by levers in the box connecting the wheels to be moved down, either completely lifted during transport on the straits or for operation to be able to be adjusted at any suitable height in the field.
Die beiden beweglichen Zahnsysteme sind jedes für sich mittelst Gelenkstangen und Federn aufgehängt. Diese Construction bezweckt sowohl eine minimale. Reibung der beweglichen Theile, als auch ein leichtes Ausweichen der schwingenden Zähne bei etwaigen Stöfsen an Steine. Um die beweglichen Zahnsysteme beim Fahren auf der Strafse aufser Thätigkeit zu setzen, ist das konische Getriebe durch einfache Kupplung ein- und ausrückbar gemacht. Bei steinigem Acker läfst sich hiermit auch leicht ein in Art der Pferdeschlepphacken construirter Steinfänger verbinden.The two movable tooth systems are each by means of articulated rods and springs hung up. This construction aims at both a minimal. Friction of the moving Partly, as well as a slight evasion of the vibrating teeth in the event of a bump Stones. In order to keep the movable tooth systems out of action when driving on the street the conical gear can be engaged and disengaged by a simple clutch. This can also be used on stony fields easily connect a stone catcher constructed in the manner of a horse-drawn hoe.
