PATENTAMT.PATENT OFFICE.

Bei den bekannten Mähmaschinen macht sich der Übelstand bemerkbar, daß sich zwischen die Messer und die diese gegen die Führung des Messerbalkens pressenden Messerhalter leicht Fremdkörper, wie Gras, Sand u. dgl., einziehen und sich zwischen beiden festsetzen, wodurch der leichte Gang des Messers nachteilig beeinflußt und die Mäharbeit trotz Erhöhung des durch die verstärkteIn the known mowing machines, the drawback is noticeable that between the knives and the knife holders pressing them against the guide of the knife bar easily pull in foreign bodies such as grass, sand and the like and get stuck between the two, which makes the knife easy to move adversely affected and the mowing work despite increasing the increased by the

ίο Reibung bedingten Kraftaufwandes verringert wird.ίο Friction-related effort is reduced will.

Diese Nachteile sucht die vorliegende Erfindung dadurch zu beheben, daß auf den Messern eine Schutzschiene angebracht ist, welche die Messerhalter übergreift, so daß die zwischen Messerbalken und Messerhaltern vorhandene Fuge abgedeckt ist.The present invention seeks to overcome these disadvantages by relying on the Knives a guard rail is attached, which engages over the knife holder so that the The joint between the cutter bar and the cutter holder is covered.

Eine solche Schutzvorrichtung für das Schneidwerk von Mähmaschinen ist in den Fig. ι und 2 der Zeichnung in einer Ausführungsform dargestellt, wobei Fig. 1 einen Schnitt und Fig. 2 die Draufsicht zeigt.Such a protective device for the cutting unit of mowing machines is in the Fig. Ι and 2 of the drawing in one embodiment shown, wherein Fig. 1 shows a section and Fig. 2 shows the plan view.

Auf dem Messerbalken α, welcher in einer Ausnehmung der Finger b gleitet, sind in bekannter Weise die einzelnen Messer c befestigt, welche in Abständen durch die Messerhalter d, die mit der Fingertragschiene β verschraubt sind, niedergedrückt werden. Gemäß der Erfindung sind auf den Messern sich über zwei Messer erstreckende Schutzschienen f befestigt, welche die Messerhalter d übergreifen und dadurch die zwischen diesen und den Messern vorhandenen Fugen bei jeder Lage des Messerbalkens abdecken. Die Messerhalter sind mit einem nach unten gerichteten, nicht zur Erfindung gehörigen Ansatz g versehen, durch welchen der Messerbalken a in einer solchen Entfernung vom Fingerträger e gehalten wird, daß zwischen beiden ein hinreichend großer, eine Verstopfung ausschließender Spalt verbleibt. Durch die Rippen g wird der Messerbalken nach vorn gedrückt. An Stelle mehrerer Schutzschienen kann eine sich über die ganze Länge des Messerbalkens erstreckende Schiene verwendet werden.On the cutter bar α, which slides in a recess of the fingers b , the individual knives c are attached in a known manner, which are pressed down at intervals by the knife holder d, which are screwed to the finger support rail β. According to the invention, protective rails f extending over two knives are attached to the knives, which overlap the knife holder d and thereby cover the joints between these and the knives in every position of the knife bar. The knife holders are provided with a downwardly directed approach g , which does not belong to the invention, by means of which the knife bar a is held at such a distance from the finger support e that a sufficiently large gap to prevent clogging remains between the two. The cutter bar is pushed forward by the ribs g. Instead of several protective rails, a rail extending over the entire length of the cutter bar can be used.
