An der durch Patent 125272 geschützten tragbaren Aussägemaschine soll nachstehende Verbesserung angebracht werden.The following is intended to apply to the portable sawing machine protected by patent 125272 Improvement.
Bisher wurde nach Fertigstellung eines Aus-Schnittes das Maschinengestell mittels einer einzigen durch ein Zahngetriebe abwärts bewegten, sich gegen das Werkstück stützenden Zahnstange aufgekippt, zum Zwecke, die Säge ohne erheblichen Kraftaufwand in das nächste vorgebohrte Loch einsetzen zu können.So far, after the completion of a cut-out, the machine frame was by means of a single downwardly moved by a toothed gear rack supported against the workpiece tilted up, for the purpose, the saw without considerable effort in the next pre-drilled Hole to be able to use.
Bei der neuen Anordnung ist die Bauart so getroffen, daß sich die ganze Maschine gleichmäßig hochhebt. An jeder Kopfseite der Maschine befindet sich eine Rolle r, welche beiderseits in je eine Stange s gelagert ist. Jede der Stangen s wird genau senkrecht geführt. Auf Bolzen b drehbar angeordnet befinden sich an den Längsseiten der Maschine je zwei doppelarmige Hebel h, welche durch einen in der äußeren Längswandung befindlichen Schlitz hindurchtreten und außerhalb der Maschine durch je einen Holzgriff g miteinander verbunden sind.In the new arrangement, the design is such that the whole machine is raised evenly. At each head side of the machine there is a roller r, which is mounted in a rod s on each side. Each of the rods s is guided exactly vertically. Arranged rotatably on bolts b , there are two double-armed levers h on each of the longitudinal sides of the machine, which pass through a slot in the outer longitudinal wall and are connected to one another outside the machine by a wooden handle g.
Das dem Holzgriff entgegengesetzte Ende der Hebel h besitzt ein Zahnsegment ^, welches in die mit einer Zahnstange versehene Führungsstange s der Rollen r eingreift. Bewegt man nun die an den beiden Längsseiten der Maschine befindlichen Holzgriffe g, mithin auch die Hebel h nach oben, so drücken die Zahnsegmente die Stangen s, also auch die Rollen r nach unten, bezw. die ganze Maschine nach allen Seiten gleichmäßig nach oben.The end of the lever h opposite the wooden handle has a toothed segment ^ which engages in the guide rod s of the rollers r, which is provided with a toothed rack. If you now move the wooden handles g located on the two long sides of the machine, and therefore also the levers h upwards, the toothed segments press the rods s, i.e. also the rollers r downwards, respectively. the whole machine upwards evenly on all sides.
