Unterhalb oder innerhalb des Cylinders a ist ein zur Hälfte mit Zähnen versehenes Schalträdchen b oder ^1 angebracht, in welch letzterem die Stange c des Transporteurs geführt ist.The conveyor, which rotates automatically when working with the machine, "serves to produce round or oval seams on footwear. Below or inside the cylinder a is a half-toothed switching wheel b or ^ 1 , in which the rod the rod c of the carrier.
An dem Hebelarm d ist ein Hebel e drehbar angebracht; ferner ist an dem Nähmaschinenarm / der Winkelhebel h drehbar befestigt, dessen einer Schenkel mit dem Hebel e verbunden, der andere Schenkel mit dem Schalthebel i derart in Verbindung steht, dafs je nach der Befestigung desselben in ο oder ο' das Schalträdchen b um einen oder zwei Zähne fortgerückt wird, was die herzustellende Rundung der Naht bedingt.A lever e is rotatably attached to the lever arm d; also is rotatably attached to the sewing machine arm / the angle lever h , one leg of which is connected to the lever e , the other leg is connected to the switching lever i in such a way that depending on the attachment of the same in ο or ο 'the switching wheel b by one or two teeth is moved away, which causes the rounding of the seam to be produced.
Der Hebelarm d hat seinen Drehpunkt in k, und es erfolgt bei jedem Hub desselben die Fortrückung des Rädchens b und des damit verbundenen Transporteurs c, so dafs letzterer, nach erfolgter Drehung um i8o°, die punktirte Stellung cx eingenommen hat.The lever arm d has its fulcrum in k, and with each stroke of the same there is the advancement of the wheel b and the associated conveyor c, so that the latter, after having turned through 180 °, has assumed the punctured position c x .
Soll die Schaltvorrichtung aufser Thätigkeit gesetzt werden, so ist der Schalthebel auszurücken. If the switching device is to be put into action, the switching lever must be disengaged.
