ABSTRACT OF THE DISCLOSURE A drive mechanism particularly for household appli- ances, includes a driving element, a driven element and a fric- tional clutch coupling for frictionally transmitting motion between these two elements. The coupling includes a dished spring fixedly connected to one of these elements and frictionally engaging the other of these elements, whereby normally transmit motion between these elements. The spring is of a material which deforms upon heating so that relative motion between these elements resulting in frictional heating of the dished spring causes the same to de- form out of engagement with the other element and thereby inter- upt the transmission of motion between the elements. -1-
