  Vorrichtung zum Herausschneiden des   Kesselsteines   aus Rohren. 



   Mit llilfe vorliegender Vorrichtung ist man in der Lage, den Kesselstein, welcher sich in   neu Rohre, von Wasserrohrkesseln   und dergl. festgesetzt hat, in schraubenförmige Streifen zu zerschneiden und diese aus dem Rohre zu entfernen. 



   Zu diesem   Bohufo   sind an einem Schneidkopfe eine Anzahl   Meissel   oder Schneiden in einer Schraubenlinie angeordnet, welche sich in den Kesselstein in einer Schraubenlinie einschneiden und dadurch von demselben schraubenförmige Streifen lostrennen. Um das Werkzeug für verschiedene Rohrdurchmesser verwenden zu   kÖnnen, sind diese Meissel   oder Schneiden verstellbar eingerichtet. 



   In der beiliegenden Zeichnung ist eine   Ausführungsform einer solchen Vorrichtung   dargestellt, u. zw. in Fig. 1 in der Stirnansicht, in Fig. 2 im   Längsschnitt   und in Fig. 3 in der Seitenansicht. 



     Die Vorrichtung besteht aus einem cyiindrischen Schneidkopf jf,   auf dessen Stirnseite sich eine Anzahl radialer, tiefer und zweckmässig in einer centralon Vertiefung zusammen   taufender Nuthen, 3   befindet. In diesen Nuthen sind Backen 3 geführt, an welchen 
 EMI1.1 
 geordnet sind, dass sie sämmtlich in einer Schraubenlinie von für die   Härte dos Kessel-   steines geeigneter Ganghöhe liegen.

   Die Anwendung der Vorrichtung erfolgt in der Weise, dass die Schneiden ungefähr auf den lichten Durchmesser des betreffenden Rohres eingestellt und die Vorrichtung in das Rohr eingedreht wird. Die Schneiden schneiden sich allmählich in einer Schraubenlinie in   do) mehr oder weniger   festen Kesselstein ein und zerlegen denselben in schrauben-   förmige Streifen. welche von der Rohrwand abspringen   und durch   Zurückziehen   der Vorrichtung aus dem Rohre geschafft werden können.

  Device for cutting out the scale from pipes.



   With the aid of the present device one is able to cut the scale, which has set in new pipes, water-tube boilers and the like, into helical strips and remove them from the pipe.



   For this Bohufo a number of chisels or cutting edges are arranged in a helical line on a cutting head, which cut into the scale in a helical line and thereby separate helical strips from the same. In order to be able to use the tool for different pipe diameters, these chisels or cutting edges are adjustable.



   In the accompanying drawing, an embodiment of such a device is shown, u. between in Fig. 1 in the front view, in Fig. 2 in longitudinal section and in Fig. 3 in the side view.



     The device consists of a cylindrical cutting head jf, on the end face of which there are a number of radial grooves 3 which are deeper and suitably together in a central depression. In these Grooves 3 jaws are performed, on which
 EMI1.1
 are ordered so that they all lie in a helix of a suitable pitch for the hardness of the boiler stone. In order, on the one hand, to use the device for any pipe diameter and, on the other hand, to be able to set the cutting edges after creation to a given diameter, according to the embodiment shown
 EMI1.2
 



   The device is used in such a way that the cutting edges are set approximately to the inside diameter of the pipe in question and the device is screwed into the pipe. The cutting edges cut gradually in a helical line in do) more or less solid scale and break it up into helical strips. which jump off the pipe wall and can be removed from the pipe by pulling back the device.
