ABSTRACT:
An electro-mechanical actuator for sewing machine instrumentalities which allows settings to be made electrically using low level electrical signals, and then acts upon such signals mechanically using power derived from the sewing machine drive. Cam-actuated feeler elements are urged by the sewing machine drive to close upon an inclined surface, previously positioned in accordance with a low level electrical input signal by, for example, a galvanometer, resulting in an angular displacement of the feeler elements proportionate to the positioning of the inclined surface.
