Die Erfindung bezieht sich auf Baumsägen, deren Sägeblatt drehbar in einem aus Rohr bestehenden Sägebogen eingespannt ist. Erfindungsgemäß ist das Sägeblatt nun dadurch drehbar und feststellbar, daß die flachgedrückten beiden Enden des Sägebogens mit Nocken versehen sind, die in Rasten von Stellhülsen eingreifen, die undrehbar auf den Sägeblattbolzen sitzen. Die Stellhülsen haben zweckmäßig die Form von Flügelmuttern. Die SpannungThe invention relates to tree saws, the saw blade of which is rotatable in a tube made of pipe Saw arch is clamped. According to the invention, the saw blade can now be rotated and locked, that the flattened two ends of the saw bow are provided with cams that snap into place engage by adjusting sleeves, which sit on the saw blade bolts in such a way that they cannot be rotated. The adjusting sleeves have appropriate the shape of wing nuts. The voltage ίο des Sägebogens hält seine Nocken im Eingriff mit den Rasten der Stellhülsen und ermöglicht deren Drehung zusammen mit dem Sägeblatt. Die üblicherweise vorhandene Mutter zum Spannen des Sägeblattes liegt auf der einen Stellhülse auf.ίο the saw bow keeps its cams engaged with it the locking of the adjusting sleeves and enables their rotation together with the saw blade. Usually The existing nut for tensioning the saw blade rests on one of the adjusting sleeves. In der Zeichnung ist die Baumsäge in einem Ausführungsbeispiel dargestellt. Von den einzelnen Abbildungen zeigtIn the drawing, the tree saw is shown in one embodiment. From the individual Illustrations shows Abb. ι die Baumsäge in einer Seitenansicht,
Abb. 2 das untere Ende des Sägebogens in etwa natürlicher Größe,
Fig. Ι the tree saw in a side view,
Fig. 2 the lower end of the saw bow in about natural size,
Abb. 3 die Unteransicht dieses Sägebogenendes nach Weglassung der Stellhülse und der Spannmutter, 'Fig. 3 the bottom view of this end of the saw curve after omitting the adjusting sleeve and the clamping nut, ' Abb. 4 einen Schnitt nach der Linie A-B der Abb. 2.Fig. 4 shows a section along the line AB in Fig. 2. Das Sägeblatt 1 ist mit seinen Sägeblattbolzen 2 in dem Sägebogen 3 eingespannt. Aus den beiden Kopfenden des Sägebogens sind Nocken 4 herausgepreßt, und zwar, wie Abb. 3 und 4 zeigen, zweckmäßig in solcher Weise, daß sie nicht bis zum Außenrande der Kopfenden reichen, um deren Biegefestigkeit möglichst wenig zu beeinflussen. Die Nocken 4 greifen in Rastenausschnitte 5 von Stellhülsen 6 und 7, die undrehbar auf den Sägeblattbolzen 2 sitzen. Die obere Stellhülse 7 ist auf ihrem Sägeblattbolzen verstiftet (Abb. 1), die untere Stellhülse 6 hat ein Vierkantloch, durch welches der kantige Sägeblattbolzen hindurchgeht. Bei Pat ε ν τα ν s ρ r 0 c η ε :The saw blade 1 is clamped in the saw bow 3 with its saw blade bolts 2. From the two Cams 4 are pressed out at the head ends of the saw bow, as shown in FIGS. 3 and 4, expediently in such a way that they do not extend to the outer edge of the head ends, around their To influence the flexural strength as little as possible. The cams 4 engage in notch cutouts 5 of Adjusting sleeves 6 and 7, which sit non-rotatably on the saw blade bolts 2. The upper adjusting sleeve 7 is on pinned to its saw blade bolt (Fig. 1), the lower adjusting sleeve 6 has a square hole through which the angular saw blade bolt goes through it. At Pat ε ν τα ν s ρ r 0 c η ε: Drehung der beiden Stellhülsen 6 und 7 wird somit das Sägeblatt mitgenommen, wobei die Rasten der Stellhülsen 6 und 7 über die Nocken 4 der beiden Kopfenden des Sägebogens hinwegspringen. Die Federung des Sägebogens hält die Nocken 4 in Eingriff mit ihren Rasten 5 und damit das Sägeblatt in der ihm gegebenen Winkelstellung. Zur Spannung des Sägeblattes ist auf das aus der unteren Stellhülse 6 vorstehende Ende der Sägeblattbolzen 2 eine Flügelmutter 8 aufgeschraubt.Rotation of the two adjusting sleeves 6 and 7 thus entrains the saw blade, with the notches of the adjusting sleeves 6 and 7 jump over the cams 4 of the two head ends of the saw bow. The suspension of the saw bow holds the cams 4 in engagement with their notches 5 and thus the saw blade in the angular position given to him. To tension the saw blade is on the one from the bottom Adjusting sleeve 6 protruding end of the saw blade bolt 2 a wing nut 8 screwed on. Auf Grund der Wirkungsweise der beschriebenen Erfindung ist die äußere Form der Stellhülsen, wie auch die Bildung der Rastennocken an den Kopfenden des Sägebogens ohne Bedeutung und kann daher im Rahmen der Erfindung von der in der Zeichnung dargestellten Ausführung abweichen. Due to the mode of operation of the invention described, the outer shape of the adjusting sleeves, as well as the formation of the notch cams at the head ends of the saw arch is of no importance and can therefore deviate within the scope of the invention from the embodiment shown in the drawing.
