Solange sich nun in dem Vorschubrohre oino Materialstange befindet und die Backen seines Spannmauls diese fest umgreifen und somit auch das Vorschubrohr feststellen, kann eine zufällige, den Spielräumen zwischen Vorschubdaumen f und Hülsennut des Vorschubrohres 33 entsprechende Verschiebung des Vorschubrobres gegenüber der Materialbülse nicht eintreten ; dies ist aber dann leicht möglich, wenn keine Materialstange in dem

Vorschuhrohros zu verhindern (sind bisher bei Revolverdrehbänken der beschriebenen Art an dem Maschinengestell besondere Supporte vorgesehen. Diese tragen einen Führungsring, auf den die entsprechend gestalteten hinteren Kopfteile der Vorschabrohro auftaufen, so dass eine nicht beabsichtigte Verschiebung dieser Rohre gegenüber den Materialhülsen nicht stattfinden kann.
Nach vorliegender Erfindung sind nun diese Supporte, sowie der Führungsring und die Einstellvorrichtungen dadurch vollkommen entbehrlich gemacht, dass die Materialbülse 30 mit einer nach innen gerichteten Feder a ausgestattet ist, die gegen das Vorschubrohr wirkt und dadurch dieses auch dann gegen eine zufällige Längsverschiebung sichert, wenn kein Material mehr vorhanden ist. Wie aus Fig. 3 ersichtlich, kann diese Feder, statt besonders an dem Vorschubrohre angebracht zu sein, auch aus einem entsprechend nach innen gebogenen Ausschnitt des Rohres 30 gewonnen werden.

As long as there is a material bar in the feed tube and the jaws of its clamping jaw grip it tightly and thus also determine the feed tube, an accidental displacement of the feed tube relative to the material sleeve, corresponding to the gaps between the feed thumb f and the sleeve groove of the feed tube 33, cannot occur; but this is easily possible if there is no material bar in the

To prevent front shoe tubes (special supports have so far been provided on the machine frame of turret lathes of the type described. These carry a guide ring on which the appropriately designed rear head parts of the front tube head so that an unintended displacement of these tubes relative to the material sleeves cannot take place.
According to the present invention, these supports, as well as the guide ring and the adjustment devices are completely dispensable in that the material sleeve 30 is equipped with an inwardly directed spring a, which acts against the feed tube and thereby also secures it against accidental longitudinal displacement when no more material is available. As can be seen from FIG. 3, this spring, instead of being attached specifically to the feed pipe, can also be obtained from a cutout of the pipe 30 that is correspondingly bent inward.
