ABSTRACT:
A motor driven drapery closure is provided with means for operating the closure between defined opened and closed positions without the use of limit switches. Means are also provided to stop the operation of the motor and back it up slightly if a significant resistance is met by the closure at a point midway of its travel or as a result of coming to the designed end of its travel. Additional means are provided for operating the closure in response to means for sensing an outside ambient condition such as the level of infrared light.
