  • Patent number: 4313389
    Abstract: A sewing machine comprises a housing, a needle bar adapted for reciprocating movement by a main shaft rotatably mounted in the housing and a fabric feeding device. A pattern control device is provided in the sewing machine which includes a number of needle bar control cams and fabric control cams operated by the main shaft. Two manually operated pattern selecting arrangements are mounted in the housing of the sewing machine including cams and cam followers and which are operatively connected to the fabric feeding device to control the movement thereof. In accordance with these pattern selecting arrangements the minimum rotation angle of the operating dial is made considerably large for selecting one of the pattern cams to thereby provide relatively small push angles for operating cam followers.
