ABSTRACT:
A drive for the work feed mechanism of a sewing machine comprises a stepping motor which is secured to a support connected to the housing of the sewing machine in a manner permitting rotary displacement and whose output shaft is connected to the setting shaft of a control mechanism by which the feed amount and direction of a feed dog is determined. To facilitate the adjustment of the angular step position of the stepping motor, the setting shaft of the control mechanism is mounted coaxially of the axis of displacement of the support of the stepping motor. To obtain a compact construction, the setting shaft of the control mechanism is supported in a bushing which is firmly connected to the support and fitted, but angularly displaceable and secured by clamp, in an open bearing of the sewing machine housing.
