    Putzstift für Vorrichtungen zum Bearbeiten der Oberfläche von Gussstücken mit radial beweglichen Putzstiften.   



   Gegenstand der Erfindung ist ein Putzstift für Putz- und Schleifvorrichtungen mit radial   beweglichen Putzstiften nach   Patent Nr. 74355, bei welchen die Putzstifte nicht nur radial verschiebbar sind, sondern auch eine kreisende Bewegung ausführen können. 



   Es hat sich nun herausgestellt, dass sich bei dermassen beweglich gelagerten Stiften die Enden der Stifte nach kürzerem Gebrauch infolge der allseitigen Beweglichkeit kugelförmig abnutzen. Daher ist die   Angriffsfläche   der Stifte nach kurzem Gehrauch nicht mehr so scharf wie im Anfang, wenn die Stirnfläche noch kantig ist. 



     Da :, Ist   ein nicht zu unterschätzender Nachteil, der durch die Erfindung behoben werden soll. Diese besteht darin, dass die Putzstifte eine Durchbohrung erhalten, also einen   rohrförmigen   Schaft, so dass auch bei Abnutzung der Stimflächen der Stifte diese stets scharfkantig sind, nämlich die Randkanten der Innen- und Aussenfläche der Stifte erhalten bleiben. 



   In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen   Ausführungbi'orm   dargestellt, und zwar zeigt Fig. 1 im Schnitt eine Putztrommel mit den neuen Putzstiften, Fig. 2 einen Schnitt durch den Putzstift selbst. 



   Der Putzstift c, mit einer durchbohrung i versehen, ist derart   rohrförmig     gtUdtct. daLi

    Cleaning pin for devices for processing the surface of castings with radially movable cleaning pins.



   The subject of the invention is a cleaning pin for cleaning and grinding devices with radially movable cleaning pins according to patent no. 74355, in which the cleaning pins are not only radially displaceable but can also perform a circular movement.



   It has now been found that with such movably mounted pins the ends of the pins wear spherically after a short period of use due to the mobility on all sides. Therefore, after a short hearing, the contact surface of the pins is no longer as sharp as it was at the beginning, when the front surface is still angular.



     Since:, is a disadvantage that should not be underestimated and which the invention is intended to remedy. This consists in that the cleaning pins receive a through-hole, i.e. a tubular shaft, so that even when the end faces of the pins are worn, they are always sharp-edged, namely the marginal edges of the inner and outer surfaces of the pins are retained.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment, namely FIG. 1 shows in section a cleaning drum with the new cleaning pins, FIG. 2 shows a section through the cleaning pin itself.



   The cleaning pin c, provided with a through-hole i, is tubular in this way gtUdtct. dali
