Abstract
This disclosure relates to an electromagnetic selector system for selecting pattern cams in a sewing machine wherein operator influenced electric pattern selection switches are provided with each said switch corresponding to a pattern on a pattern cam. An adder mechanism is responsive to switch selection for positioning a pattern cam follower in order to transmit the pattern information from the pattern cam to the appropriate sewing instrumentality for reproducing the selected pattern.
Claims16
In a sewing machine having stitch forming instrumentalities, mechanism in said sewing machine responsive to pattern information for regulating at least one of said stitch forming instrumentalities including, a plurality of aligned pattern cams each carrying pattern information, pattern cam follower means including a single cam follower for selectively sensing the pattern information from said pattern cams and for regulating the stitch forming instrumentalities, adder means operably connected to said cam follower means for selectively associating said pattern cam follower means with a pattern cam, and electric switch means for selecting individual patterns of stitches, said switch means being connected to said adder means for initiating association of said pattern cam follower means with a pattern cam carrying pattern information corresponding to the selection of said switch means.
In a sewing machine having stitch forming instrumentalities, mechanism in said sewing machine responsive to pattern information for regulating at least one of said stitch forming instrumentalities including, a plurality of aligned pattern cams with each said cam carrying pattern information, a pattern follower mechanism including a single pattern cam follower for selectively sensing pattern information from any one of said pattern cams and for transmitting pattern information to said one of said stitch forming instrumentalities, and electric motor means responsive to operator influenced switch means and operative for permitting movement of said cam follower to a non-operative position with respect to said stitch forming instrumentalities.
In a sewing machine having stitch forming instrumentalities, mechanism in said sewing machine responsive to pattern information for regulating at least one of said stitch forming instrumentalities including, a plurality of aligned pattern cams each carrying distinctive pattern information, a pattern follower mechanism including a single pattern cam follower for sensing pattern information from any one of said pattern cams and for transmitting pattern information to said one of said stitch forming instrumentalities, said pattern cam follower being movable relative to said plurality of pattern cams for selective association therewith, an electrically influenced pattern selection mechanism including electric motor means operatively connected to said cam follower for removing said cam follower from operative engagement with said pattern cams, an operator influenced selector area, switch means operatively associated with said electric motor means and said operator influenced selector area, said switch means operative in response to an operator influenced selection of said selector area for initiating operation of said electric motor means thereby permitting movement of said cam follower for selective association with said plurality of aligned pattern cams.
