   auf den Kolben wirkender Luftpolster entstehen. Bei vorkommenden längeren Arbeitspausen   wird aber der Luftdruck   über dem Kolben schon   bei der allergeringsten Undichtheit soweit sinken, dass   der pneumatische Kolben allein   das Ableiern des Schwungrades, zufolge der hoben Steigung der Spindel, nicht verhindern kann. Um dieser Gefahr   zuverlässig   vorzubeugen, ist entsprechend dem Grunkgedanken dieser Erfindung eine Kombination der pneumatischen Bremse mit einer Feder vorgesehen. Diese Feder wird nur soweit gespannt, dass sie den Kolben gerade noch mit solchem Druck an das   Schwungrad anpresst, dass   dieses nicht   ableiern   kann. 



   An Stelle der   pneumatischen   kann auch eine hydraulische Bremse zur Anwendung kommen, welche beispielsweise nach der in Fig. 3 gezeigten Ausführung aus einem in dem hohlen Ende des Tragarmes   I   verschiebbaren Zylinder u besteht, der Glyzerin oder eine andere Flüssigkeit enthält und in dem sich ein an der Stange   @   festgehaltener Kolben w befindet. Dieser Kolben ist mit einer durchgehenden, die beiden Zylinderräume verbindenden Bohrung x und ferner mit einem unter Federdruck stehenden Ventil y versehen, das in geöffneter Stellung den raschen Übertritt von   Flüssigkeit   aus dem einen Zylinderraum in den anderen vermittelt.

   Der   Zylinder   wird durch eine Feder z ständig nach unten gedrückt.

   Air cushions acting on the piston are created. If longer work breaks occur, the air pressure above the piston will drop even with the slightest leak so that the pneumatic piston alone cannot prevent the flywheel from deflecting due to the increased incline of the spindle. In order to reliably prevent this risk, a combination of the pneumatic brake with a spring is provided in accordance with the concept of this invention. This spring is only tensioned to such an extent that it presses the piston against the flywheel with such pressure that it cannot deflect.



   Instead of the pneumatic one, a hydraulic brake can also be used which, for example according to the embodiment shown in FIG. 3, consists of a cylinder u which can be displaced in the hollow end of the support arm I and which contains glycerine or another liquid and in which a the rod @ held piston w is located. This piston is provided with a through bore x connecting the two cylinder chambers and also with a spring-loaded valve y which, in the open position, enables fluid to pass quickly from one cylinder chamber to the other.

   The cylinder is constantly pressed down by a spring z.
