  Sägenschäfvorrichtung. 



   Es ist bekannt, Sägen mittels umlaufender entsprechend profilierter Feilkörper zu schärfen, die mit einem Schaltfinger versehen sind, durch den der Transport des   Sägeblattes   bewirkt wird. 



   Diese bekannten Vorrichtungen haben jedoch den Nachteil, dass sie auf die Schränkung des Sägeblattes   ungunstig einwirken,   da dasselbe immer in der gleichen Richtung von dem Feilkörper beansprucht wird, wodurch die   Schrankung des-Sägeblatteseinerseits   aufgehoben wird. Auch beansprucht das Schärfen mit bekannten Vorrichtungen relativ viel Zeit, da nur jeweils ein Zahn   geschärft werden   kann.

 Drehachsen vorgesehen sind, wobei der Schaltfinger der Feilkörper das Sägeblatt um das Mass zweier Zähne weiterschaltet.

Das Kegelrad 9 erhält durch einen Triebling 12, dessen Achse 13 maschinell oder von Hand mittels Kurbel angetrieben wird, seine Bewegung, die durch die über Gleitrollen 14 geführte Kette 7 und Kettenräder 6 auf die beiden Feilkörperspindeln 2 übertragen wird, wodurch diese eine gleichsinnige Drehbewegung erhalten.

  Saw-cutting device.



   It is known to sharpen saws by means of circumferential, appropriately profiled filing bodies which are provided with a switching finger through which the saw blade is transported.



   However, these known devices have the disadvantage that they have an unfavorable effect on the set of the saw blade, since the same is always stressed in the same direction by the file body, whereby the set of the saw blade on the one hand is canceled. Sharpening with known devices also takes a relatively long time, since only one tooth can be sharpened at a time.
 EMI1.1
 Axes of rotation are provided, the index finger of the filing body indexing the saw blade by the amount of two teeth.



   In the drawing the invention is for example. illustrates u. Between shows: FIG. 1 a view from the front, FIG. 2 a side view and FIG. 3 a schematic view from above.



   The sharpening device essentially consists of two parallel bearings
 EMI1.2
 Chain wheels 6 attached to the filing body spindles, which are driven by a chain 7 from a chain wheel 8 which is fastened below the bearings 1 and 3 together with a bevel wheel 9 on a shaft 10 of the bearing 11. The bevel gear 9 receives its movement from a pinion 12, the axis 13 of which is driven mechanically or by hand by means of a crank, which is transmitted to the two filing spindles 2 by the chain 7 and sprockets 6 guided over sliding rollers 14, whereby these receive a rotational movement in the same direction .
 EMI1.3
 the filing body 4 and 5 has been introduced (FIG. 3), the filing bodies 4 and 5 are set in rotation and each sharpen one tooth of the saw blade 15 at the same time.

   After the file body approximately
