Title: Drapery actuator system and method of operation

Abstract: A drapery opening and closing system for opening and closing a single drape or two drapes, and a method of opening and closing a drape. A reversible electric motor, to which a winch member is rotatably coupled, is affixed to a wall proximate a window at an approximate mid-vertical height of such window. An elongate cord having a first end fixed to the wall and another coupled to such winch member, encircles the drape. Upon actuate of the motor, adjustable timing means permits operation of the motor for a predetermined interval of time to allow the elongate cord to be wound onto such winch member, thereby causing the cord encircling the drape to constrict and thereby bunching the drape together thereby drawing it from the window. Reversal of the direction of the winch allows unwinding of the cord to thereby allow the drape to fall back into position thereby covering the window.
