Laubsäge.Fretsaw.

Patentirt im Deutschen Reiche vom 4. Juli 1893 ab.Patented in the German Empire on July 4, 1893.

In dem am oberen Ende der Laubsägemaschine befestigten Gehäuse A bewegt sich der Kolben B mit der Führungsstange C, gespannt durch die Spiralfeder D. Die Spindel E ist in. der Kolbenstange C durch Muttern F und G verstellbar und hält durch die Backen H den oberen Theil der Säge J. Durch die hin- und hergehende Bewegung des Kolbens B wird unter Mitwirkung des Saugventils K und des Druckventils L die Luft an die Arbeitsstelle geblasen, um dieselbe rein zu halten. In the housing A attached to the upper end of the fretwork, the piston B moves with the guide rod C , tensioned by the spiral spring D. The spindle E is adjustable in the piston rod C by nuts F and G and holds the upper part by the jaws H. the saw J. By the reciprocating movement of the piston B , with the assistance of the suction valve K and the pressure valve L, the air is blown to the work site in order to keep it clean.
