Abstract

An air distribution blower housing has an adjustable restriction in the interior of the blower housing. The adjustable restriction has the configuration of a rectangular plate. One edge of the plate is connected by a pivoting connection to an interior wall of the blower housing in the air flow path from the blower housing. The plate can be pivoted about the pivot connection through a plurality of adjusted angular positions of the plate in the air flow path. In each adjusted position of the plate, the length of the plate extends from the pivot connection in the air flow direction. A sliding connection is provided between the plate and at least one side wall of the blower housing. The sliding connection selectively holds the plate in its adjusted angular position and also provides a visual indication on the exterior of the blower housing of the adjusted angular position of the plate inside the blower housing.
