ABSTRACT:
The sewing machine is provided with two knobs on the front face of the machine housing and a number of switches indicating different stitch patterns to be produced. These knobs may be selectively pushed or rotated to set the sewing machine between a condition in which the needle and the feeding device are set to produce predetermined stitch coordinates of a selected pattern and a condition in which the needle and the feeding device are adjusted to produce adjustable stitch coordinates. The sewing machine further includes switches operated by the aforementioned knobs and an electric memory connected to a manually operated controller and functioning for controlling the swinging amplitude of the needle and the feeding pitch of the feeding device.
