Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung besteht in einer Vorrichtung", das Sägeblatt bei Steinsägen anzuheben, um Schleifsand unter dasselbe gelangen zu lassen. Der in der Zeichnung mit ι bezeichnete Rahmen läuft in einem Schlitten 2, der an Ketten oder Seilen 3 aufgehängt ist. Diese sind über Rollen 4 geleitet, die durch ein Kniegelenk 5, 6, 7, Daumenrad, Winkelhebel o. dgl. zeitweise mechanisch oder von Hand angehoben werden, so daß der Schleifsand beim Heben des Sägeblattes 8 unter dasselbe fallen kann. Mittels Stufenscheiben 9 und Räderübersetzung 10 kann die Vorrichtung so eingestellt werden, daß das Blatt 8 sich entweder nach jeder einzelnen Bewegung oder auch erst nach zwei-, drei- oder mehrmaligem Spiel hebt.
Der Sägeblattrahmen 1 ist mittels Rollen in einem Schlitten 2 wagerecht geführt, so daß das Sägeblatt auf seiner ganzen Länge einen geraden Schnitt erzeugt. Der an den Ketten oder Seilen 3 aufgehängte Schlitten 2 ist ebenfalls beiderseits geführt, so daß er nur eine senkrechte Bewegung machen kann.The present invention consists in a device "to lift the saw blade in stone saws in order to let grinding sand get under it which are temporarily lifted mechanically or by hand by a knee joint 5, 6, 7, thumb wheel, angle lever or the like, so that the grinding sand can fall under the same when the saw blade 8 is lifted be set so that the sheet 8 lifts either after each individual movement or only after playing two, three or more times.
The saw blade frame 1 is guided horizontally by means of rollers in a carriage 2 so that the saw blade produces a straight cut over its entire length. The carriage 2 suspended from the chains or ropes 3 is also guided on both sides so that it can only make one vertical movement.
