ABSTRACT A shade operator includes a drive unit having a central stud forming the axis of rotation for the shade roller. A manually operable pulley is mounted on the stud, and is engageable with a coil spring clutch member mounted about the stud coaxial with the pulley. The shade roller is engaged by a bushing which is also mounted for rotation on the stud. The bushing is provided with a projection which engages the clutch spring due to the weight of the shade and causes the spring to further grip the stud to prevent rotation. Operation of the pulley engages the spring such that its grip on the bushing is loosened, which allows the spring, bushing and shade roller to be driven by the pulley as desired to raise or lower the shade. Halting of pulley rotation allows the spring clutch to fully re-engage the stud to keep the shade at the new desired location.
