(57) A window covering is disclosed that has a first rail (1), a double spool (4) connected
to the first rail (1), at least one motor (13) connected to the first rail (1), and
window covering material (2) extending from the first rail (1). A plurality of primary
lift cords (9) extends from the first spool portion (22) of the double spool (4) and
is connected to the window covering material (2) such that rotation of the double
spool (4) in a first direction extends the window covering material (2) away from
the first rail (1) and rotation of the double spool (4) in an opposite second direction
retracts the window covering material (2) toward the first rail (1). One or more secondary
cords (11) extend from the second spool portion (22) of the double spool (4) and are
connected to the one or more motors (13).
