ABSTRACT:
A selecting device for a double-function sewing machine having a single drive motor with the sewing machine including a first stitch forming mechanism to produce one type of stitch, a second stitch forming mechanism to produce another type of stitch, and a transmission for transmitting the rotation of the drive motor to the first and second stitch forming mechanism. The selecting device includes a first clutch operated into an operative position to contact the first stitch forming mechanism to a transmission and operated into an inoperative position to disconnect that mechanism from the transmission, and a second clutch operated into an operative position to connect the second stitch forming mechanism to the transmission and operated into an inoperative position to disconnect that mechanism from the transmission. A manually operated dial is mounted on the housing of the sewing machine, which is connected to a lever mechanism operated in one direction to hold the first mentioned clutch in the inoperative position and release the second clutch into the operative position. The lever mechanism is manually operated in another direction to hold the second clutch in the inoperative position and release the first clutch into the operative position.
