Sewing machine pattern selection system

A multiple pattern sewing machine having instrumentalities for forming a succession of stitches individually placed in a selected one of a plurality of different patterns, said sewing machine including a static pattern memory means in which a multiplicity of separate digitally coded words are stored in a predetermined sequence with each word corresponding to one individually placed stitch in a pattern, an address memory means in which separate signals are stored in a numerical sequence each addressing the starting code word address in said static pattern memory means for a different one of said plurality of patterns, means for providing timing pulses related to the formation of successive stitches by said sewing machine, means utilizing said timing pulses for addressing digital code words in said static pattern memory means in said predetermined sequence beginning with said starting word identified by an address memory signal, means effective automatically to return to said starting word identified by said address memory signals to repeat said predetermined sequence, and actuating means responsive to said predetermined sequence of digitially coded words and operatively connected to said stitch forming instrumentalities for influencing said stitch forming instrumentalities to form a selected pattern in response thereto, the improvement which comprises a pattern selection means rendered effective by manipulation of a single operator influenced pattern selector switch means for selecting any one of said pluralities of different patterns, said pattern selection means comprising:

• a. a pattern selector switch means accessible to a sewing machine operator on said sewing machine,
• b. a pattern selection counter arranged to deliver as an output to said address memory means a predetermined numerical sequence including at least a portion of that in which said separate signals are stored in said address memory, and
• c. means effective in response to actuation of said pattern selector switch means for indexing said pattern selection counter through said predetermined numerical sequence.
