Description

Bahngreifer für Nähmaschinen Die Erfindung betrifft eine weitere Ausgestaltung des durch Patent 575 384 geschützten Bahngreifers für Nähmaschinen und biezweckt, ein leichtes Abheben des Deckels zu ermöglichen. Zu diesem Zweck werden an diesem oder an dem Greifergehäuse federnde Mittel angeordnet, die beim Lüften der Befestigungsschrauben den Deckel des Greifergehäuses selbsttätig abheben. Beielner bevorzugten Ausführungsform werden um die Befestigungsschrauben gelegte Schraubenfedern vorgesehen, die den Deckel des Grei-. fergehäuses aufwärts drücken.Web gripper for sewing machines The invention relates to a further embodiment the web hook for sewing machines and bending purposes protected by patent 575 384, to allow the lid to be lifted off easily. To this end, be on this or arranged on the gripper housing resilient means when releasing the fastening screws Lift off the cover of the hook housing automatically. Beielner's preferred embodiment coil springs placed around the fastening screws are provided, which the Lid of the gryphon. press the housing upwards.

In den Zeichnungen ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt, und zwar ist Fig. i eine Rückansicht des Greifers im Schnitt, wobei der Deckel geschlossen ist, und Fig. 2 zeigt dasselbe wie Fig. i mit dem Unterschied, daß der Deckel von dem Greifergehäuse abgehoben ist.In the drawings is an embodiment of the subject matter of the invention for example shown, namely Fig. i is a rear view of the gripper in Section with the lid closed, and FIG. 2 shows the same as FIG with the difference that the cover is lifted from the gripper housing.

Die Brücke i, das Gr eiferg'ehäuse i 7 und der Deckel 24 sind unwesentlichen so wie beim Hauptpatent ausgebildet.The bridge i, the grip housing i 7 and the cover 24 are insignificant as with the main patent.

Hingegen sind die Befestigungsschrauben 26 nicht in das Greifergehäuse 17, sondern in die Brücke i eingeschraubt. Das Greifergehäuse 17 ist an den Stellen des Durchtritts der Befestigungsschrauben 26 mit Bohrungen 34 versehen, die so groß sind, daß um die Befestigungsschrauben 26 gelegte Schraubenfedern 35 in ihnen Platz haben. Im geschlossenen Zustand (Fig. i) des Deckels sind die Schraubenfedern 35 zusammengedrückt. Werden die Befestigungsschrauben aus ihrer Stellung in Fig. i um 9o° im Sinne einer Lösung der Verbindung gedreht, so können die mit parallelen Flachseiten versehenen Schraubenköpfe durch die der Form der Schraubenköpfe entsprechenden Schlitze 27 des Deckels hindurchtreten. In dieser Stellung drücken die Schraubenfedern 35 den Deckel 24 aufwäxts, und letzterer kann daher leicht abgehoben werden (s. Fig.2).In contrast, the fastening screws 26 are not screwed into the gripper housing 17, but into the bridge i. The gripper housing 17 is provided at the points of passage of the fastening screws 26 with bores 34 which are so large that coil springs 35 placed around the fastening screws 26 have space in them. In the closed state (FIG. I) of the cover, the coil springs 35 are compressed. If the fastening screws are rotated 90 ° from their position in FIG. In this position, the coil springs 35 press the cover 24 upwards, and the latter can therefore be easily lifted off (see FIG. 2).
