PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist eine doppeltwirkende Kaltsäge, bei welcher sich zwei Sägeblätter beifszangenartig einander nähern und das Werkstück, ohne dafs ein Rest stehen bleibt, vollständig durchschneiden.The present invention is a double-acting cold saw in which Two saw blades approach each other like a pair of pliers and the workpiece without leaving a residue remains, cut through completely.
Die Einrichtung der Säge ist folgende:The setup of the saw is as follows:
Mit einem von einer Kurbelscheibe in der Bahn (J1 a2 (Fig. 1) hin- und herbewegten, in der Zeichnung nicht dargestellten Schlitten ist ein um die Achse α schwenkbarer Arm b verbunden, in dessen vorderes bügelartiges Ende das obere Sägeblatt c eingespannt ist. In dem Bügel der oberen Säge sind zwei Stäbe lie angeordnet und durchstellschrauben befestigt, auf welchen sich der mit entsprechenden Bohrungen versehene Bügel f der unteren Säge auf- und abbewegen läfst.An arm b pivotable about the axis α is connected to a slide, not shown in the drawing, which is reciprocated by a crank disk in the path (J 1 a 2 (FIG. 1)) and the upper saw blade c is clamped in its front bow-like end In the bracket of the upper saw, two rods are arranged and fastened through adjusting screws, on which the bracket f of the lower saw, which is provided with corresponding bores, can be moved up and down.
An der Bügelstange e befindet sich ein verstellbares Lager h für den Hebel i mit Handgriff k und Gewicht /.An adjustable bearing h for the lever i with handle k and weight / is located on the bow bar e.
Drückt man den Handgriff k nieder, so gehen die Sägen aus einander und lassen das Werkstück g frei. Läfst man k los, so prefst das Gewicht I die beiden Sägen gegen einander und beide gleichmäfsig gegen das Werkstück. If the handle k is pressed down, the saws move apart and leave the workpiece g free. If you let go of k , the weight I prefers the two saws against each other and both evenly against the workpiece.
Die Fig. 2, 3 und 4 zeigen, dafs, auch wenn die Zahnung beider Sägeblätter nach Lage und Form der Zähne nicht genau übereinstimmt, das Werkstück dennoch vollständig durchschnitten wird.2, 3 and 4 show that, even if the teeth of both saw blades according to position and The shape of the teeth does not exactly match, but the workpiece is completely cut through will.
