Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Benutzung, von Sägeschnüren, die a»is einem oder mehreren spiralförmig zusammengewundenen Drähten hergestellt sind, kann es vorkommen, dafs die Drahtwindungen zu weit aus einander gezogen werden. Um dies zu verhindern und um überhaupt die Drahtwindungsabstände zu regeln, wird in den durch die Drahtwindungen gebildeten Kanal 0, Fig. 1 und 2, eine Seele c aus einem Draht oder aus mehreren Drähten eingelegt, deren Enden mit passenden Verstärkungen η (Plättchen, Schraubenmuttern "etc., etwa von einem Durchmesser, der dem äufseren Durchmesser der Spiralsägeschnur gleich ist) versehen sind, um die Ausdehnung der Spiralen auf ein gewisses Mafs zu beschränken. Sofern es sich um die Herstellung von SpiralsägeschnUren ohne Ende landelt, werden die Enden der Seele c, wie luch die. Enden der Spiralen s durch Löthen, Schweifsen, Schrauben u. s. w. mit einander vereinigt. Auf diese Weise wird nicht allein dem Auseinandergehen der Windungen eine Grenze gesetzt, ■ sondern zugleich auch die Dauerhaftigkeit und Schneidwirkung der. Säge vergröfsert. In beiliegender Zeichnung ist durch Fig. ι (Ansicht) und Fig. 2 (Längsschnitt) eine aus einem einzigen Draht gewundene Spiralsägeschnur mit Drahtseele dargestellt. Fig. 3 zeigt eine solche Sägeschnur, welche aus mehreren neben einander gelegten. Drähten sls2s3 hergestellt ist. Die Seele c1 ist mit punktirten Linien gezeichnet.When using saw cords made of one or more spirally wound wires, it can happen that the wire windings are pulled too far apart. In order to prevent this and to regulate the wire winding spacing at all, a core c made of one wire or several wires is inserted into channel 0, Fig. 1 and 2, formed by the wire windings, the ends of which are reinforced with suitable reinforcements η (plates, nuts "etc., approximately of a diameter that is equal to the outer diameter of the spiral saw cord) are provided in order to limit the expansion of the spirals to a certain extent. If it comes to the manufacture of spiral saw cords without end, the ends of the soul c as Luch the. ends of the spirals s by Löthen, Schweifsen, screws, etc. combined with each other. In this way, not only the divergence of the coils is set a limit vergröfsert ■ but also the durability and cutting action of the. saw. In the enclosed Drawing is through Fig. Ι (view) and Fig. 2 (longitudinal section) a spiral saw cord wound from a single wire with a wire core posed. Fig. 3 shows such a saw cord, which consists of several laid next to each other. Wires s l s 2 s 3 is made. The soul c 1 is drawn with dotted lines.
