  Haltevorrichtung   filr   den Arbeitsstahl bei   Pressluftwerkzellgen.   



   Es ist bekannt, bei Pressluftwerkzeugen eine   Haltevorriehtung   vorzusehen, die am Werkzeugkopf befestigt ist und ein Auge besitzt, das den Schaft, nicht aber den Bund des Arbeitsstahles durchtreten lässt. Es ist auch bekannt, zum leichteren Einlegen das Auge so zu gestalten, dass es geöffnet werden kann. Demgegenüber besteht die Erfindung darin, dass das Auge selbst geschlossen bleibt und so bemessen ist, dass auch der Bund   durchschlüpfen   kann, dass aber, nachdem das Eisen eingelegt ist, der   Durchsehlupf   des Bundes durch einen besonderen, einschwenkbaren Riegel verhindert wird. 



   In der Zeichnung ist der Gegenstand der Erfindung in Fig. 1 im Längsschnitt und in Fig. 2 im Schnitt nach A-B der Fig.   l   dargestellt. 



   Am Zylinderdeckel   a   ist mittels der Bolzen b, die in bekannter Weise abgefedert sind, die Brücke c befestigt, die ein Auge d besitzt, durch das der Bund e des Arbeitsstahles hindurchtreten kann. Die Brücke c wird durch die   Büchsen t im   Abstande vom Zylinderdeckel gehalten. Auf einer dieser   Büchsen   ist ein Riegel g schwenkbar aufgesetzt ; dieser Riegel ist klauenartig ausgestaltet, so dass er sich um den Schaft des Arbeitsstahles herumlegen kann, ohne aber den Bund e durchzulassen.

   Damit der Riegel g, der das Auge d gegen den Durchsehlupf des Bundes e   verschliesst,   eine feste Einlagerung erfährt, besitzt er den Kragen h, der in das Auge d eintritt, wobei die Feder i mitwirkt, gegen welche der   Riegel g, wenn   er geöffnet werden soll, auf der Büchse f zurückgeschoben werden muss.

  Holding device for the working steel in compressed air work cells.



   It is known to provide a holding device in compressed air tools that is attached to the tool head and has an eye that allows the shaft, but not the collar, of the working steel to pass through. It is also known to design the eye so that it can be opened for easier insertion. In contrast, the invention consists in that the eye itself remains closed and is dimensioned so that the collar can slip through, but that, after the iron has been inserted, the collar is prevented from being pulled through by a special, pivotable bolt.



   In the drawing, the object of the invention is shown in Fig. 1 in longitudinal section and in Fig. 2 in section A-B of FIG.



   The bridge c, which has an eye d through which the collar e of the working steel can pass, is attached to the cylinder cover a by means of the bolts b, which are spring-loaded in a known manner. The bridge c is held at a distance from the cylinder cover by the bushes t. A bolt g is pivotably mounted on one of these sleeves; this bolt is designed like a claw so that it can lie around the shaft of the working steel, but without letting through the collar e.

   So that the bolt g, which closes the eye d against the penetration of the collar e, experiences a firm storage, it has the collar h, which enters the eye d, whereby the spring i acts against which the bolt g when it is opened to be pushed back on the sleeve f.
