ABSTRACT:
A driving mechanism for a sewing machine includes a rotatable shaft coupled to one or more needles for moving the needles upward and downward in a reciprocating action. A rotary looper is rotatably secured to the sewing machine at a vertical axle and is coupled to the shaft for allowing the shaft to actuate the needles and the rotary looper simultaneously. A rod is vertically secured in the sewing machine and coupled to the rotary looper for rotating the rotary looper. Two bevel gears are secured to the rod and the shaft for allowing the shaft to rotate the vertical rod.
