Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine elektrisch betriebene Kreissäge, welche im Gegensatz zu den bisher bekannten Kreissägen, die nur in einer Richtung schneiden können, so ausgebildet ist, daß sie am Flaschenzug aufgehängt in Marmor-, Tuffstein-, Kalk-, Kreidebrüchen, ferner in Eis auf Eisflächen und in senkrecht stehenden Wänden beliebigen Materials zu schneiden vermag.The invention relates to an electrically operated circular saw, which in contrast to the previously known circular saws, which can only cut in one direction, so designed is that they are hung on the pulley in marble, tuff, lime, chalk quarries, furthermore in ice on ice surfaces and in vertical walls of any material able to cut.
ίο Der Erfindungsgegenstand unterscheidet sich gegenüber den bisher bekannten transportablen Steinsägen mit Kreisscheiben durch die Anordnung zweier dicht nebeneinander angeordneten, in entgegengesetzten Richtungen umlaufenden Kreisscheiben; dadurch wird bezweckt, den Arbeitsdruck auf den Bedienungsmann auszugleichen. ίο The subject matter of the invention is different compared to the previously known portable stone saws with circular disks due to the arrangement two arranged close to each other, rotating in opposite directions Circular disks; the purpose of this is to equalize the work pressure on the operator.
Es sind zwar Blattsägen bekannt, deren Sägeblätter dicht nebeneinander angeordnet sind und sich in verschiedenen Richtungen bewegen. Derartige Sägen sind aber nicht transportabel. Blade saws are known whose saw blades are arranged close together are moving in different directions. However, such saws are not transportable.
Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes schematisch dargestellt, und zwar zeigt:An embodiment of the subject matter of the invention is shown schematically in the drawing, namely shows:
Fig. ι eine Ansicht der Säge,
Fig. 2 einen Grandriß mit Anordnung von zwei Motoren,Fig. Ι a view of the saw,
Fig. 2 is a plan with an arrangement of two motors,
Fig. 3 einen Grundriß mit Anordnung eines Motors.Fig. 3 is a plan view showing the arrangement of an engine.
In dem Rahmengestell α α' sitzen Elektromotoren b V und auf der Achse der Motoren die beiden Kreissägeblätter c c'. Der Rahmen ist nach hinten heraus mit einem Handgriff d zum Fortbewegen der Säge versehen. Ferner sitzen am Rahmengestell Rollen e, f und g sowie zwei Hebelarme h h' mit Rollen i i'. Diese Hebelarme sind verstellbar angeordnet, um zu ermöglichen, auf einer wagerechten Ebene, wie in Fig. 1 in ausgezogenen Linien dargestellt ist, oder auf einer senkrechten Ebene, wie in Fig. 1 in strichpunktierten Linien angedeutet ist, schneiden zu können. Bei der Ausführungsform nach Fig. 3 werden beide Kreissägeblätter durch einen gemeinsamen Motor durch Kegelräder angetrieben. Soll die Säge fortbewegt werden, so wird das Rahmengestell aus der gezeichneten Stellung nach links herübergekippt, so daß die ganze Säge auf den Rollen f, i i' ruht. Die Kreis-Sägeblätter berühren dann nicht den zu schneidenden Gegenstand oder die Erde, können mithin an eine beliebige Stelle geführt werden.In the frame α α ' sit electric motors b V and on the axis of the motors the two circular saw blades c c'. The frame is provided to the rear with a handle d for moving the saw. Furthermore, rollers e, f and g and two lever arms hh ' with rollers i i' sit on the frame. These lever arms are arranged to be adjustable in order to make it possible to cut on a horizontal plane, as shown in solid lines in FIG. 1, or on a vertical plane, as indicated in dash-dotted lines in FIG. 1. In the embodiment according to FIG. 3, both circular saw blades are driven by a common motor through bevel gears. If the saw is to be moved, the frame is tilted over to the left from the position shown, so that the entire saw rests on the rollers f, ii '. The circular saw blades then do not touch the object to be cut or the earth and can therefore be moved to any point.
