KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Es ist bekannt, zur Herstellung von Schlitzen und Nuten in Hölzern geneigt zu ihrer Drehachse stehende Kreissägen, sogenannte Taumelsägen, zu benutzen, welche je nach der Breite des herzustellenden Schlitzes in ihrer Neigung verstellt werden können. Bei größerer Schlitzbreite verwendet man zwei nebeneinander auf eine Welle angebrachte Taumelsägen. Den Gegenstand der Erfindung bildet nun eine besonders einfache Anordnung einer aus zwei Kreissägeblättern bestehenden Taumelsäge, bei welcher die beiden Sägeblätter gegeneinander geneigt stehen. Wie die Fig. ι und 2 zeigen, sind zwei nebeneinander gelagerte Sägeblätter a und a1 in der Mitte durch einen bekannten Füllring in bestimmtem Abstand gehalten. Die Neigung zur Achse wird einesteils durch Zusammenziehen mittels Verschraubung d, anderseits durch Auseinanderdrücken mittels diametral gegenüberliegender Druckschraube c erreicht. Die Druckschraube c sitzt in einer Mutter b, welch letztere mittels Schrauben 1 und 2 an dem Kreissägeblatt α befestigt ist.It is known to use circular saws, so-called wobble saws, which are inclined to their axis of rotation for producing slots and grooves in wood, the inclination of which can be adjusted depending on the width of the slot to be produced. With a larger slot width, two wobble saws attached to a shaft are used. The subject of the invention now forms a particularly simple arrangement of a wobble saw consisting of two circular saw blades, in which the two saw blades are inclined to one another. As FIGS. 1 and 2 show, two saw blades a and a 1 mounted next to one another are held in the middle by a known filler ring at a certain distance. The inclination to the axis is achieved on the one hand by pulling it together by means of a screw connection d and on the other hand by pushing it apart by means of a diametrically opposed pressure screw c . The pressure screw c sits in a nut b, which the latter is attached to the circular saw blade α by means of screws 1 and 2. Durch verschiedene Einstellung der Druckschraube kann in einfacher Weise, da die Sägeblätter federnd nachgeben, die Neigung der von der Achse aus divergierenden Blatthälften verändert und somit die Schlitzbreite in gewissen Grenzen beliebig gewählt werden. Die in den Kreissägen angeordneten Löcher i ermöglichen ein entsprechend leichtes Durchfedern.By adjusting the pressure screw differently, the inclination of the blade halves diverging from the axis can be changed in a simple manner, since the saw blades yield resiliently, and the slot width can thus be selected as desired within certain limits. The holes i arranged in the circular saws allow a correspondingly slight deflection.
