Abstract
A fully automatic motor driven curtain drawing apparatus which is of a simple, but highly reliable design and one which can be easily adjusted to accommodate windows of widely differing sizes. They can be opened either manually or by an electric motor which can be remotely energized. A timer and a sensor are operably connected to the electric motor and function to energize the motor either at a predetermined time or in response to the sensor sensing daylight and dark.
