Abstract

A drapery actuator to open and close draperies, comprising a housing and a drive pulley supported by the housing to engage a drapery cord coupled to a drape. A motor, typically a D.C. motor, is supported by the housing for providing torque to reversibly rotate the drive pulley to move the drapery cord between a first extreme (typically closed) position and a second extreme (typically open) position. A first electrical switch operatively connected to the motor functions as a cut-out switch and reversing switch to stop the motor from continued turning in a given direction and thereafter switching polarity, to allow the motor to turn in an opposite direction when the switch is re-activated. A torque-activated mechanism is provided, adapted to actuate the first electrical switch when the drive pulley moves the drapery cord to the first position, and is further adapted to actuate the first electrical switch when the drive pulley is reversibly rotated by the motor to move the drapery cord to the second position.
