Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung bezieht sich auf den weiteren Ausbau der durch das Patent 238508 geschützten lösbaren Mähmesserbefestigung für die Messer von Mähmaschinen, soweit die Festlegung der Messer zwischen dem Messerkopf und dem Messerbalken in Betracht kommt.The present invention relates to the further development of the patent 238508 protected detachable mower blade attachment for the blades of mowing machines, as far as the Establishing the knife between the cutter head and the cutter bar comes into consideration.
Beim Festlegen der Messer am Messerbalken allein bleibt die Verschraubung derjenigen des Hauptpateiites entsprechend.When fixing the knives on the cutter bar, only the screw connection remains of the main file site accordingly.
Um jedoch die Vorteile des Hauptpatentes in erhöhtem Maße zu erreichen, ist über den Schraubenbolzen eine konisch verlaufende Beilage geschoben, die teilweise in den Messerstab und teilweise in die Messerklinge zu liegen kommt, so daß nicht allein die Vorteile des Hauptpatentes erreicht werden, sondern überdies jegliche Verschiebung des Messerstabes oder der Messerklinge mit Sicherheit vermieden wird, während andererseits die Schrauben nicht unwesentlich entlastet werden. However, in order to achieve the advantages of the main patent to an increased extent, is about the Screw bolt a tapered shim pushed partially into the knife stick and partly to lie in the knife blade, so that not only the advantages of the main patent, but also any displacement of the knife stick or the knife blade is avoided with certainty, while on the other hand the screws are not insignificantly relieved.
Die neue Verschraubung ist in Fig. 1 und 2 der beiliegenden Zeichnung in einem Schnitt und in einer Draufsicht veranschaulicht.The new screw connection is shown in Fig. 1 and 2 of the accompanying drawings in a section and illustrated in a plan view.
Wie aus der Zeichnung hervorgeht, besteht die Verschraubung aus der Schraube a mit dem zylindrischen Kopf b und der kegelförmig gestalteten Mutter c, die, um ein bequemes Anziehen zu ermöglichen, mit Schlitzend für einen Schlüssel ausgestattet ist, während der Kopf b der Schraube ebenfalls Schlitze e aufweist. Damit nun eine sichere Verbindung der Messer mit dem Messerkopf i und dem Messerstab g erzielt wird, sind nicht allein in den Messern f, sondern auch im Messerstab g kegelartig gestaltete Ausnehmungen angeordnet, in welche einerseits die Mutter c, andererseits eine konische Beilage h, die über den Schraubenbolzen zu schieben ist, zu liegen kommt. Da nun die Beilage h teilweise in die Messerklinge f und teilweise in den Messerstab g zu liegen kommt, so wird beim Anziehen der Schraube nicht allein eine innige Verbindung des Messerkopfes i mit dem Messer f und dem Messerstab g erzielt werden, sondern die Beilage h wirkt jeder seitlichen Verschiebung der miteinander verbundenen Teile mit Sicherheit entgegen. Gleichzeitig werden aber die Schrauben nicht unwesentlich entlastet.As can be seen from the drawing, the screw connection consists of the screw a with the cylindrical head b and the conical nut c, which is equipped with slots for a key to allow easy tightening, while the head b of the screw also has slots e has. So that a secure connection of the knife with the knife head i and the knife stick g is achieved, not only in the knives f, but also in the knife stick g, cone-like recesses are arranged, in which on the one hand the nut c and on the other hand a conical insert h, the to be pushed over the screw bolt comes to rest. Since the attachment h now comes to lie partly in the knife blade f and partly in the knife stick g , when the screw is tightened, not only an intimate connection of the knife head i with the knife f and the knife stick g is achieved, but the supplement h acts certainly counteracts any lateral displacement of the interconnected parts. At the same time, however, the load on the screws is not insignificantly relieved.
