ABSTRACT:
An ornamental stitch sewing machine has a drive shaft with a first cam mounted on the shaft for axial movement. The cam is tracked by a tracking element. A second cam is adapted to be removably mounted on the shaft in superposed relation to the first cam and when so mounted displaces the first cam so that it is rendered ineffective and the tracking element responds only to the second cam. Upon removal of the second cam the first cam is again rendered effective for tracking by the tracking element.
