KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Der vorliegende Rohrabschneider unterscheidet sich von den bisher gefertigten Werkzeugen gleicher Art in der Hauptsache durch seine Verstellbarkeit, d. h. man kann Röhren von 30 mm- bis zu 250 mm Durchmesser damit zerschneiden.The present pipe cutter differs from the tools manufactured up to now of the same kind mainly through its adjustability, d. H. you can use tubes Use it to cut from 30 mm to 250 mm in diameter.

Der Apparat liefert ferner einen glatten, kreisrunden Schnitt, da derselbe mit einem Drehstahl arbeitet, während der gröfste Theil der bis jetzt gefertigten gleichartigen Werkzeuge mit Schneidrädern arbeitet, welche das Rohr nicht zerschneiden, sondern von einander drücken und dadurch sehr oft dasselbe beschädigen. The apparatus also provides a smooth, circular cut as the same with a turning tool works while the greater part of the tools of the same kind manufactured up to now works with cutting wheels, which do not cut the pipe, but from each other press and thereby very often damage the same.

Der Rohrschneider (Fig. 1) wird vermittelst der Spannschrauben α <xl auf dem abzuschneidenden Rohr befestigt, wodurch sich die Rollenpaare b b1 des Bügels E, sowie die im Kopf A angeordneten Einzelrollen c c1 fest an das Rohr legen, und da sich die Rollen sämmtlich drehen, bewirken sie, dafs der Apparat leicht um das Werkstück herum bewegt werden kann und übernehmen gleichzeitig die Führung des Werkzeuges. The pipe cutter (Fig. 1) is attached to the pipe to be cut by means of the clamping screws α <x l , whereby the pairs of rollers bb 1 of the bracket E, as well as the individual rollers cc 1 arranged in the head A are firmly attached to the pipe, and since the Turning the rollers as a whole, they cause the apparatus to be easily moved around the workpiece and at the same time take over the guidance of the tool.

Durch Versetzen der Rollenpaare b b1, Fig. 1, auf die im Bügel E, Fig. 2, angebrachten Zapfen d1 d2 d 3 wird die Verstellbarkeit erzielt; da, je nachdem die Rollen von einander stehen, die Stützpunkte verlegt werden und, wie oben erwähnt, man in der Lage ist, jede beliebige Dimension bis zur Gröfse von 250 mm Durchmesser zu schneiden, so ersetzt das Werkzeug drei bis vier der bisherigen Constructionen.The adjustability is achieved by moving the pairs of rollers bb 1 , FIG. 1, onto the pins d 1 d 2 d 3 mounted in the bracket E, FIG. 2; Since the support points are relocated depending on how the rollers stand apart and, as mentioned above, one is able to cut any dimension up to a diameter of 250 mm, the tool replaces three to four of the previous constructions.

Am Kopf A ist seitlich ein Support B mit einem gewöhnlichen Drehstahl C angeordnet, welcher durch die Schraube D angespannt wird und durch Drehen des ganzen Werkzeuges um das Rohr herum, welche Manipulation sich leicht vermöge der Rollen bewirken läfst, letzteres zerschneidet, nicht, wie bei den mit Rädern arbeitenden Apparaten, abdrückt.On the side of the head A there is a support B with an ordinary turning tool C , which is tightened by the screw D and by turning the whole tool around the tube, which can easily be manipulated by means of the rollers, cuts the latter, not as in the machines that work with wheels.

Claims (1)

Patent-Anspruch:Patent claim: Ein Rohrabschneider mit einem seitlich arbeitenden Support als Träger für den Schneidstahl, dadurch gekennzeichnet, dafs zur Benutzung desselben für beliebig starke Rohre in einem Bügel (E) mehrere Stifte (d) eingesetzt sind, die zur Aufnahme versetzbarer Stahlrollen (b) dienen, welche, im Verein mit den gleichen Rollen (c) am Kopf A, die Führung des Apparates auf dem Werkstück übernehmen.A pipe cutter with a laterally working support as a carrier for the cutting steel, characterized in that several pins (d) are inserted in a bracket (E) to use the same for pipes of any thickness, which are used to accommodate displaceable steel rollers (b) which, in association with the same roles (c) on head A, take control of the apparatus on the workpiece.
