Abstract
A lead screw window operator () utilizes a lead screw () that is in tension whether the operator is being used to open or close a window assembly (). The lead screw window operator () may include a nut () that has edges sufficiently close to first and second support surfaces to prevent excess rotation of the nut (). Also, the lead screw () may have a splined end to operatively connect to a first gear that has a splined profile to allow the gear to slide along the lead screw along a longitudinal axis.
