Abstract
Abstract A system is disclosed in which a plurality of sewing machine stitch patterns are stored in a static memory. Digital information related to the positional coordinates for each stitch of a plurality of stitch patterns is stored in a static memory. Each stitch pattern is automatically obtained upon activation of an operator actuated pattern selector switch which generates a digital code representative of the pattern selected. The pattern code word is latched and coupled to an address memory which provides a continuous fixed output of a digital code representative of the first word (stitch) in the selected pattern. The address memory is coupled to a counter which counts the pulses provided by a pulse generator which is driven in timed relation with the sewing machine drive shaft. The signal pulses are counted up in the counter to provide a timed series of progressively increasing binary numbers corresponding to the progressively increasing number of stitches in the pattern. The counter output is coupled to and functions as the address to the pattern memory which provides a digital output therefrom with information related to the positional coordinates for each stitch of a selected pattern. The output of the memory is coupled to an actuating means operatively connected to impart a controlled range of movement to the conventional stitch forming instrumentality of the sewing machine to produce a specific predetermined position coordinate for the needle penetration during each stitch formation. A unique code word is provided from the pattern memory output upon the completion of a selected pattern. This end of pattern code word is coupled to the address counter and resets it to the address originally coupled thereto thus, providing a continuously repeating stitch pattern.
