Abstract
A room air conditioning unit has an air flow guide mechanism which provides an oscillating-type of air sweep louvered grill for the unit discharge duct. A motor with suitable gear reduction supplies power to a double acting barrel cam having a curved surface matching the radius of the center of rotation of the grill assembly to a point of contact of a follower fixed to the air conditioner unit front cabinet housing. The cam has a groove receiving the follower to transmit the desired amount of movement to rock the guide mechanism about a horizontal axis to provide a vertical air sweep. An eccentric pin on the cam drives a vertical louvered actuating rack to generate horizontal air sweep. The cam follower may be disengaged from the cam groove when vertical air sweep action is not desired.
