ABSTRACT:
A drapery opening and closing system is provided for draw drapes which are movable over a traverse member between an open and closed position by use of a drape drive system. The opening and closing system has limit switches positioned to be activated when the drapes are opened and closed. A manually settable timer connected to a power source applies power at preset times to a reversible motor via a control circuit. The control circuit is comprised of a relay activated by the timer and a series connected two-section switch. Outputs of the two-section switch are connected to the reversible motor through the limit switches. When the timer is triggered at a preset time, the drapes automatically open or close. Via the two-section switch, the drapes may be manually activated to open or close at times other than the preset times on the timer.
