Description

Vorrichtung zur Herstellung von Zickzackstichen an Haushaltsnähmaschinen Nach dem Hauptpatent werden die Zickz ackstiche dadurch hergestellt, daß die Drückerfußstange mit dem daran befindlichen Drückerfuß pendelnd aufgehängt ist und von einer schwingenden Kulisse durch Hebel und Lenker hin und her geschwungen wird. Vorliegende Erfindung zeigt eine Weiterausbildung, deren Wesen darin besteht, daß der Drückerfuß an einem Zwischenhebel angeordnet ist, der an der eigentlichen Drückerfußstange um einen Bolzen verschwengbar und in bekannter Anordnung durch Steuerkurve und Kulisse verschwenkt wird.Device for making zigzag stitches on household sewing machines According to the main patent, the zigzag stitches are produced by the presser foot bar with the presser foot attached to it is suspended pendulum and by a swinging The backdrop is swung back and forth by levers and handlebars. Present invention shows a further training, the essence of which is that the presser foot on a Intermediate lever is arranged on the actual presser foot bar around a The bolt can be swiveled and is pivoted in a known arrangement by means of the control cam and the backdrop will.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigen: Abb. i eine Seitenansicht und Abb. 2 die Vorderansicht der Nähmaschine mit der Vorrichtung.In the drawing, the invention is shown in one embodiment. They show: Fig. I a side view and Fig. 2 the front view of the sewing machine with the device.

An der Drückerfußstange a ist um einen Bolzen b verschwenkbar ein Zwischenhebel c angebracht, der den Drückerfuß trägt und mit seinem Führungsstück d in dem Kopfstück e des zweiarmigen Hebels f lose gleitend angeordnet ist. Der Hebel f ist durch den Lenker g mit der Kulisse lt, die in bekannter Weise durch eine Steuerkurve o. dgl. ausgeschwungen wird, verbunden. Hierdurch wird der Zwischenhebel c mit dem Drückerfuß um den Bolzen b der Nadelstange ca verschwenkt, der Stoff seitlich verschoben und der Zickzackstich erzielt. Die Größe des Zickzackstiches kann in bekannter Weise durch Verstellen des Angriffspunktes des Lenkers g in der Kulisse geregelt werden. Für Steppstich wird der Angriffspunkt des Lenkers g in den Drehpunkt der Kulisse gebracht. Die Maschine arbeitet dann als gewöhnliche Nähmaschine.An intermediate lever c is attached to the presser foot rod a so that it can pivot about a bolt b and carries the presser foot and is arranged with its guide piece d to slide loosely in the head piece e of the two-armed lever f. The lever f is connected by the link g to the link lt, which is swung out in a known manner by a control curve or the like. As a result, the intermediate lever c is pivoted with the presser foot around the pin b of the needle bar ca, the fabric is shifted to the side and the zigzag stitch is achieved. The size of the zigzag stitch can be regulated in a known manner by adjusting the point of application of the handlebar g in the backdrop. For lockstitch, the point of application of the handlebar g is brought into the pivot point of the backdrop. The machine then works as an ordinary sewing machine.

Durch die Anordnung des lose gleitenden Führungsstückes d in dem Kopfstück e kann der Drückerfuß mit dem Zwischenhebel c an der Stoffdrückerstange durch den Stoffdrückerliebel in bekannter Weise von dem Stoff abgehoben werden, wie dieses in Abb. i dargestellt ist.By arranging the loosely sliding guide piece d in the head piece e the presser foot with the intermediate lever c on the presser bar through the Fabric presser love is lifted from the fabric in a known manner, like this one is shown in Fig. i.
