1. An apparatus comprising:
- a roller tube;
a motor including a motor drive shaft and a motor casing, the motor casing mounted to rotate with said roller tube; and
a manual control including a manual control drive shaft rotatable with the motor drive shaft, said manual control structured to apply a first torque to the motor drive shaft in response to a manually applied force to cause rotation of the motor casing and said roller tube, said motor structured to apply a second torque to said roller tube to rotate said roller tube while the motor drive shaft does not rotate relative to said manual control;
wherein the first torque and the second torque are additive to increase a rate of rotation when in the same direction, or subtractive when in the opposite directions.

15. An apparatus comprising:
-
a roller tube; a motor including a motor drive shaft and a motor casing, the motor casing mounted to rotate with said roller tube; and a manual control including a manual control drive shaft rotatable with the motor drive shaft; wherein; said manual control is structured to apply torque to the motor drive shaft in response to a manually applied force to cause rotation of the motor casing and said roller tube; said motor is structured to apply torque to said roller tube to rotate said roller tube while the motor drive shaft does not rotate relative to said manual control; and while said manual control is not operated, the manual control drive shaft is substantially stationary to hold the motor drive shaft substantially stationary during operation of said motor. - View Dependent Claims (16, 17, 18)

19. An apparatus comprising:
-
a motor having a motor drive shaft and a motor casing; and a manual control drive shaft coupled to rotate selectively with the motor drive shaft; wherein; the motor casing is mounted to rotate with a roller tube; the motor drive shaft is coupled to rotate the motor casing when said manual control drive shaft is coupled to the motor drive shaft to cause rotation of the motor drive shaft; and said motor is structured to apply torque to the roller tube to rotate the roller tube while the motor drive shaft does not rotate relative to said manual control drive shaft. - View Dependent Claims (20)

21. An apparatus comprising:
-
a motor having a rotatable motor drive shaft and a motor casing, the motor casing being coupled to rotate with a roller tube; and a manual control having a rotatable manual control drive shaft coupled with the motor drive shaft; wherein; said motor is structured to apply torque to the roller tube to rotate the roller tube while the motor drive shaft does not rotate relative to said manual control; when the manual control drive shaft rotates in the same direction as the motor drive shaft, a rate of rotation of the roller tube is increased; and when the manual control drive shaft rotates in a direction opposite to direction of rotation of the motor drive shaft, the rate of rotation of the roller tube is reduced. - View Dependent Claims (22)
