KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Metallsäge.Hacksaw. Den Gegenstand vorliegender Erfindung bildet eine Metallsäge.The subject of the present invention is a hacksaw. Auf beiliegender Zeichnung ist inThe accompanying drawing shows in Fig. ι ein derartiges Sägeblatt, welches in der Richtung des gezeichneten Pfeiles arbeitet, von der gezahnten Seite aus gesehen dargestellt; Fig. Ι such a saw blade, which works in the direction of the arrow drawn, shown from the toothed side; Fig. 2 und 3 zeigen eine Seitenansicht desselben undFigs. 2 and 3 show a side view of the same and Fig. 4 ist ein Querschnitt nach A-B. Fig. 4 is a cross-section along AB. Die Schneidkanten α b der Zähne verlaufen paarweise im Winkel zu einander. Sämmtliche voreilenden Spitzen α und sämmtliche nacheilenden Spitzen b befinden sich in gleicher Höhe, nämlich in einer Ebene, welche normal auf dem Sägeblatt steht. Die Seitenflächen des letzteren sind hinter den Schneidspitzen nach einer Cylinderfläche hinterschliffen. In der Regel wird diejenige Ausführungsform gewählt, von welcher Fig. 5 den Grundrifs, Fig. 6 und 7 Seitenansichten und Fig. 8 einen Querschnitt nach C- D veranschaulicht. Dieselbe weicht von der soeben beschriebenen Einrichtung dadurch ab, dafs die voreilenden Schneidspitzen a tiefer liegen als die nacheilenden Schneidspitzen b, so dafs jeder einzelne Zahn nach der Art eines Dreh- oder Hobelstahles in Bezug auf seine Schneidkante eingestellt ist.The cutting edges α b of the teeth run in pairs at an angle to one another. All leading tips α and all trailing tips b are at the same height, namely in a plane which is normal to the saw blade. The side surfaces of the latter are relief-ground behind the cutting tips according to a cylindrical surface. As a rule, that embodiment is selected from which FIG. 5 shows the outline, FIGS. 6 and 7 side views and FIG. 8 shows a cross-section according to C-D . This differs from the device just described in that the leading cutting tips a are lower than the trailing cutting tips b, so that each individual tooth is set in relation to its cutting edge like a turning or planing steel. Patent-Anspruch:Patent claim: Metallsägen, dadurch gekennzeichnet, dafs die Schneidkanten der Zähne paarweise in Winkel zu einander verlaufen, und dafs die voreilenden, ebenso die nacheilenden Schneidspitzen in gleicher Höhe, und dafs ferner die voreilenden Zahnspitzen entweder in gleicher Höhe mit den nacheilenden oder tiefer als diese stehen.Metal saws, characterized in that the cutting edges of the teeth in pairs Angles to each other, and that the leading as well as the trailing cutting tips at the same height, and furthermore the leading tooth tips either at the same level Height with the trailing or standing lower than this.
