の切換装置。 A lock stitch forming mechanism is provided at one end of the sewing machine frame, an overlock stitch forming mechanism is provided at the other end of the sewing machine frame, and both the above-mentioned stitches are formed by operating a switching operation section provided outside the sewing machine frame. In a compound sewing machine provided with a switching mechanism for switching only one of the stitch forming mechanisms to be drivable by an electric motor, the sewing machine is supported concentrically with an upper shaft rotatably supported on the sewing machine frame and driven by the electric motor. A drive shaft 4 rotated via a belt, an overlock pulley 21 fitted on the drive shaft so as to be rotatable and prevented from sliding in the axial direction, and a hollow formed in the overlock pulley. an overlock stitch drive member 28 fitted on the outer periphery of the shaft so as to be prevented from rotating and slidable in the axial direction; an overlock spring 33 interposed between the overlock stitch drive member and the overlock pulley; , a lockstitch pulley 6 fixed to the upper shaft;
A lockstitch drive member 14 capable of sliding in the axial direction by fitting a groove formed on the outer periphery into a projection formed in a hole of the lockstitch pulley, and a lockstitch drive member 14 and the lockstitch pulley. A lockstitch spring interposed therebetween, and a switching operation piece interposed between the lockstitch driving member and the overlock stitching driving member and actuated by operation of the switching operation section. Switching device for compound sewing machines.
