Zusatz zum Patent 419686.Addendum to patent 419686.

Patentiert im Deutschen Reiche vom 19. Januar 1926 ab. Das Hauptpatent hat angefangen am 28. August 1924.Patented in the German Empire on January 19, 1926. The main patent started on August 28, 1924.

Den Gegenstand der vorliegenden Erfindung bildet eine Verbesserung der Vorrichtung nach dem Patent 419686, die darin besteht, daß die Längsträger, an welchen der Querbalken verstellbar ist, welcher zur Abgrenzung des Ausschlages des zur Bewegung des Messerrahmens dienenden Hebelwerkes dient, derart dicht nebeneinander angeordnet sind, daß zwischen ihnen nur ein lichter Abstand belassen ist, der zum Hindurchtreten des zur Anlage an den Querbalken gelangenden Armes ausreicht. Infolgedessen kann der Querbalken ganz kurz ausfallen bzw. durch einen Bolzen ersetzt werden, und es kann zurThe subject of the present invention is an improvement of the device according to the patent 419686, which consists in the fact that the longitudinal beams to which the Crossbar is adjustable, which is used to delimit the deflection of the movement the knife frame serving lever mechanism is used, so closely arranged next to each other are that between them there is only a slight distance left to pass through of the arm reaching the crossbeam is sufficient. As a result, the Cross beams fail very short or be replaced by a bolt, and it can be used to

Anlage an den Querbalken ein beliebiger Arm des Hebelwerkes bestimmt werden.Any arm of the lever system can be determined to plant on the crossbeam.

Auf der Zeichnung sind in Abb. ι und 2 zwei Ausführungsbeispiele der Vorrichtung schaubildlich dargestellt.On the drawing are in Fig. Ι and 2 two embodiments of the device shown graphically.

Wie nach dem Hauptpatent besteht auch hier die Egge in bekannter Weise aus einem an zwei Balken 1, 2 befestigten Gitterrahmen A, der lotrechte Zähne 3 trägt und auf zwei Rollenpaaren 5 ruht, die an den Abstreicherarmen ψ der im Rahmen A drehbar gelagerten Querwellen 9 angebracht sind. An diesen Querwellen 9 sind nach oben gerichtete Arme 13 befestigt, die untereinander mittels einer Stange 14 verbunden sind, die hinten mittels eines Gelenkgliedes 14" mit dem um den Zapfen 16 drehbar gelagerten Handhebel 15 in Verbindung steht.As in the main patent, the harrow also consists in a known manner of a lattice frame A attached to two bars 1, 2, which carries vertical teeth 3 and rests on two pairs of rollers 5, which are attached to the scraper arms ψ of the transverse shafts 9 rotatably mounted in the frame A. are. Upwardly directed arms 13 are attached to these transverse shafts 9 and are connected to one another by means of a rod 14 which is connected to the hand lever 15 rotatably mounted about the pin 16 at the rear by means of a joint member 14 ″.

Durch Drehung des Handhebels 15 werdenBy turning the hand lever 15

ao die Abstreicherarme 9« nach unten verschwenkt, wobei sie die Messer 3 von dem anhaftenden Unkraut, Moos u. dgl. befreien. Gleichzeitig wird durch die Einwirkung der sich gegen den Boden stützenden Räder 5 die Egge in die Höhe gehoben, so daß das abgestreifte Unkraut frei auf den Boden abfallen kann. Sobald der Handhebel 15 freigegeben wird, fällt die Egge durch Eigengewicht zurück, so daß die Messer wieder in Eingriff mit der Erde kommen, wobei ihre Eingriffstiefe durch das entsprechende Einstellen des Querbalkens 17 im voraus bestimmt wird.ao the scraper arms 9 "pivoted downward, whereby they free the knife 3 from the adhering weeds, moss and the like. At the same time, through the action of the against the ground supporting wheels 5 lifted the harrow in the air so that the stripped Weeds can freely fall to the ground. As soon as the hand lever 15 is released is, the harrow falls back under its own weight, so that the blades engage again come with the earth, with their depth of engagement by setting the Crossbar 17 is determined in advance.

Erfindungsgemäß sind die Längsträger 18 bzw. 18', an welchen der Querbalken 17 bzw.According to the invention, the longitudinal beams 18 or 18 ', on which the crossbeam 17 or

17' verstellbar ist, derart dicht nebeneinander angeordnet, daß zwischen ihnen nur ein lichter Abstand belassen ist, der zum Hindurchtreten des Armes 13 ausreicht. Als Längsträger werden entweder gelochte Flacheisen 18 (Abb. 1), an welchen der Querbalken mittels Stifte 19 gesichert wird, oder gelochte Winkeleisen 18' (Abb. 2) benutzt, in welch letzterem Falle der Querbalken durch einen Bolzen 17' ersetzt wird, der durch die in den lotrechten Armen der Winkeleisen 18' vorgesehenen Löcher durchgesteckt wird.17 'is adjustable, so close together that between them only one a clearance is left which is sufficient for the arm 13 to pass through. as Longitudinal beams are either perforated flat iron 18 (Fig. 1), on which the crossbeam is secured by means of pins 19, or perforated angle iron 18 '(Fig. 2) is used in which latter case the crossbeam is replaced by a bolt 17 ', which is replaced by the is inserted through holes provided in the vertical arms of the angle iron 18 '.
