Embodiments of the invention relates to a motorized system for moving vertical blinds, curtains, draperies, or other window coverings. Specific embodiments can, optionally, also be manually operated. When motorized, the power supply can be batteries stored or housed in a tube or portion of a shaft, with a spring biased mechanism to assist during removal and/or loading of the batteries. In a specific embodiment, the stop can be triggered by the user to remove one battery at a time, and can allow the user to load batteries in a manner in which the battery or batteries already loaded in the chamber are held in the chamber. A specific embodiment incorporates a drapery tube with a hollow interior, or drapery shaft with one or more hollow portions, to form an enclosure that can house the motor and the power supply, such as batteries. If desired, the motor controls and an optional RF receiver for the motor can also be housed within the tube. In an embodiment, the batteries can be easily changed or replaced through the end of the tube or shaft, wherein the system has a stop, or release trigger, that can allow only one battery at a time to be loaded or unloaded, to assist in loading and unloading the batteries. In an embodiment, an end cap, such as a twist lock end cap can be positioned over the end of the tube or shaft when batteries are not being loaded or unloaded.
