Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich darf der Aufdruck des Sägenblattes auf den zu sägenden Gegenstand bei Kaltsägen (Metallsägen) nur ein sehr geringer und ganz gleichmäfsiger sein, andernfalls werden die Sägen durch die ungleichmäfsige Belastung bald stumpf und unbrauchbar. Um den Aufdruck der Säge zu verringern, sind häufig Gegengewichte angewendet. Eine gleichmäfsige Belastung der Säge wird jedoch auch hierdurch nicht erreicht, indem das Gegengewicht nur für eine bestimmte Lage der Säge (meistens für halben Hub derselben) eingestellt ist, so dafs je an beiden Hubenden, wenn die Säge dem Gegengewicht am entferntesten bezw. am nächsten steht, ein Maximal- bezw. Minimalaufdruck der Säge stattfindet.As is well known, the imprint of the saw blade on the object to be sawed is allowed Cold saws (metal saws) only have to be very small and very even, otherwise the saws will soon become dull and unusable due to the uneven load. Around Counterweights are often used to reduce the pressure on the saw. A steady one Load on the saw is also not achieved by using the counterweight only set for a certain position of the saw (mostly for half the stroke of the same) so that at both ends of the stroke when the saw is furthest away from the counterweight respectively is closest, a maximum resp. Minimal imprint of the saw takes place.
Diesem Uebelstand abzuhelfen, dient die neue, in· Fig. 1 und 2 der Zeichnung dargestellte Vorrichtung. Dieselbe besteht darin, dafs, wie der Sägenrahmen, so auch das Gegengewicht verschiebbar gemacht ist in der Weise, dafs von einer Gegenkurbel an der Kurbelscheibe das Gegengewicht dem Sägenrahmen entgegengesetzt verschoben wird.This problem is remedied by the new one shown in FIGS. 1 and 2 of the drawing Contraption. It consists in the fact that, like the saw frame, so is the counterweight is made displaceable in such a way that a counter crank on the crank disk the counterweight is moved in the opposite direction to the saw frame.
Der das Sä'genblatt S tragende Rahmen G ist an einem Arm b des Hebels B verschiebbar gelagert, der, um die Kurbelachse α drehbar, auf der anderen Seite den Hebelarm C trägt, auf dem das Gegengewicht D verschiebbar gelagert ist. Von der Kurbelscheibe A aus wird mittelst Pleuelstange g vom Zapfen f aus der Sägenrahmen und vom Zapfen fl auf der Gegenkurbel F aus mittelst Pleuelstange e das Gegengewicht D in umgekehrter Bewegungsrichtung zum Sägenrahmen angetrieben bezw. in gleitende Bewegung versetzt. Der äufsersten Stellung des Sägenrahmens entspricht die äufserste Stellung des Gegengewichts, und umgekehrt. The frame G carrying the saw blade S is slidably mounted on an arm b of the lever B which, rotatable about the crank axis α , carries on the other side the lever arm C on which the counterweight D is slidably mounted. From the crank disk A by means of the connecting rod g from the pin f from the saw frame and from the pin f l on the counter crank F by means of the connecting rod e the counterweight D is driven in the opposite direction of movement to the saw frame. set in sliding motion. The outermost position of the saw frame corresponds to the outermost position of the counterweight, and vice versa.
Es wird somit durch diese Vorrichtung eine genau gleichmäfsige Sägenbelastung in jeder Lage des Sägenrahmens erzielt.This device thus results in an exactly even load on the saw in each Position of the saw frame achieved.
