ABSTRACT:
The upper feed dog for the cloth feed mechanism of a sewing machine can be moved sideways from a position opposing the sewing area to be separated from the sewing area to thus facilitate needle exchange and threading. The cloth feed mechanism of the sewing machine includes lower feed dogs which move towards and away from as well as longitudinally to a throat plate and a support member. The support member has an upper feed dog secured thereon which moves, interlocked with a driving member, in four directions above the upper surface of the throat plate with a phase in the vertical movement opposite that of the vertical movement of the lower feed dog and with a phase in the longitudinal movement identical to that of the longitudinal movement of the lower feed dog for feeding the cloth in synchronism with the lower feed dog. The support member is supported rotatably about a vertical shaft so as to oppose or separate the feed dog to or from the sewing area.
