Kupplung für ein vorteilhaft von einem Federkraftmotor anzutreibendes Treibrad mit der Nähmaschinenwelle.
Den Gegenstand vorliegender Erfindung bildet eine Kupplung für ein vorteilhaft von einem Federkraftmotor anzutreibendes Treibrad mit der Nähmaschinenwelle, die erfindungsgemäss aus einem in das Stirnende der Welle eingeschraubten, mit einer Längsnut versehenen Wellen- stummel, auf welchem das Treibrad und eine Muffe mittels in die Nut eingreifender Schrauben befestigt ist, besteht, wobei die Muffe mit einer Nase in eine Ausnehmung am Stirnende der Näb- maschinenwelle eingreift, wodurch ein unbeabsichtigtes Losschrauben des Wellenstummels verhindert wird.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigen die Fig. 1 bis 3 die Kupplungsanordnung in Vorder- bzw. Seiten- bzw. Draufsicht.

Coupling for a drive wheel to be driven advantageously by a spring motor with the sewing machine shaft.
The subject of the present invention is a coupling for a drive wheel to be advantageously driven by a spring-force motor with the sewing machine shaft, which according to the invention consists of a shaft stub screwed into the end of the shaft and provided with a longitudinal groove, on which the drive wheel and a sleeve engage in the groove Screws is attached, there is, wherein the sleeve engages with a nose in a recess at the front end of the sewing machine shaft, whereby an unintentional unscrewing of the shaft stub is prevented.
In the drawing, the subject matter of the invention is shown by way of example, namely, FIGS. 1 to 3 show the coupling arrangement in front, side and top views.
The spring motor enclosed in a housing A with the mainspring 1 is easily detachably attached to the base plate 2 of the sewing machine. A hand crank. 3 is used to wind up
