Abstract: Disclosed is a spring motor and control for use especially with window blinds. The motor comprises a storage drum having a first axis, an output drum mounted for rotation about a second axis parallel to and spaced from the first axis. A spring member is connected to and between the storage drum and the output drum to form a spring motor. The spring motor has laterally extending, spaced apart drum supports on opposite sides of the drums to support them for rotation. A coupled drive is connected to the storage and output drum whereby rotation of one of the drums in a first direction about its axis effects rotation of the other of the drums about its axis and in an opposite direction to cause winding and unwinding of the spring member between the drums.
