Abstract: A closure operator to effect remote, failsafe opening and closing of a damper, particularly a multi-fold or interlocking slat curtain damper. A frame or shell envelops a damper curtain which is capable of opening and closing an air passage through the frame or shell. A housing containing an electromechanical curtain operator is optionally positioned within or outside the frame or shell. The curtain is lifted by a tray connected to two wire cables, in response to the winding of the cable upon a takeup drum located within the housing. The principal components of the electromechanical curtain operator are a motor, planetary gear train and its associated latch mechanism which form a clutch, cable drum, speed control brake, and limit switch assembly. All of the foregoing components are protectively contained within an operator housing which is formed with an irregular shaped projecting finger which engages a mating opening formed in a damper supported bracket or in a baffle which isolates the curtain in its open position.

Abstract: An improved latching lever assembly for use in an electromechanical door holder-closer having a closer spring, a dashpot, and an electromagnet. The electromagnet actuates the lever assembly to latch the spring-dashpot combination to effect a desired door hold open position. The lever assembly comprises a lever, a fulcrum at one end of the lever, and an armature located generally at the other end of the lever and electromagnetically coupled to the electromagnet. A latching detent is located on the lever intermediate the fulcrum and armature to latch a camming roller to arrest the spring-dashpot combination when the electromagnet is energized. An armature-lever coupling spring resiliently couples the armature to the lever to enable the lever to pivot about its fulcrum during manual override of the door holder-closer without a corresponding movement of the armature relative the energized electromagnet, thereby eliminating armature release noises.
