Claim 9

An air distribution outlet device according to claim 6 having a flow control valve disposed in upstream relationship to said barrel, said last mentioned flow control valve selectively adjustable between a position substantially blocking air flow into said barrel and a position substantially unrestrictive to air flow.

Claim 10

An air distribution outlet device comprising an elongated barrel having opposed air inlet and outlet ends and an intermediate, longitudinally extending wall portion formed with a multiplicity of orifices permitting outflow of air from said barrel, a selectively adjustable, flow control valve disposed in air flow controlling relationship to the outlet end of said barrel, said valve being adjustable between a position completely blocking airflow through said outlet end and a position substantially unrestrictive to airflow through said outlet end, a said flow control valve including a damper plate pivotably mounted in the outlet end of said barrel for rotation about an axis extending in the plane of said damper plate and transversely to the longitudinal axis of said barrel, said damper plate being coextensive with the area of said outlet end and pivotable between a position transverse to the longitudinal axis of said barrel and a position aligned with the longitudinal axis, said damper plate including first and second parallel disposed plates pivotably interconnected at their axis for relative rotation in the plane of said plates, each of said first and second plates having a plurality of apertures formed therein which apertures are in registration in one relative position of said two plates permitting air flow there-through and are out of registration in another relative position of said two plates preventing air flow therethrough.

Claim 11

An air distribution outlet device comprising an elongated barrel having opposed air inlet and outlet ends and an intermediate, longitudinally extending wall portion formed with a multiplicity of orifices permitting outflow of air from said barrel, a selectively adjustable, flow control valve disposed in air flow controlling relationship to the outlet end of said barrel, said valve being adjustable between a position completely blocking airflow through said outlet end and a position substantially unrestrictive to airflow through said outlet end, a said flow control valve including a damper plate pivotably mounted in the outlet end of said barrel for rotation about an axis extending in the plane of said damper plate and transversely to the longitudinal axis of said barrel, said damper plate being coextensive with the area of said outlet end and pivotable between a position transverse to the longitudinal axis of said barrel and a position aligned with the longitudinal axis, said damper plate including first and second parallel disposed plates pivotably interconnected at their axis for relative rotation in the plane of said plates, each of said first and second plates having a plurality of apertures formed therein which apertures are in registration in one relative position of said two plates permitting air flow there-through and are out of registration in another relative position of said two plates preventing air flow therethrough.

Claim 12

An air distribution outlet device according to claim 8 wherein one of said first and second plates is pivotably mounted in the outlet end of said barrel.

Claim 13

An air distribution outlet device according to claim 8 wherein said apertures are radially segmented portions of an annular ring.

Claim 14

An air distribution outlet device comprising: an elongated barrel having opposed air inlet and outlet ends and an intermediate, longitudinally extending wall portion formed with a multiplicity of orifices around the entire periphery for a predetermined axial length permitting transverse outflow of air from said barrel, a selectively adjustable, flow contol valve disposed in air flow controlling relationship to the outlet end of said barrel for controlling axial outflow, said valve including a damper plate pivotably mounted in the outlet end of said barrel for rotation about an axis extending in the plane of said damper plate and transversely to the longitudinal axis of said barrel, said damper plate being coextensive with the area of said outlet end and pivotable between a position transverse to the longitudinal axis of said barrel and a position aligned with the longitudinal axis and adjustable between a position completely blocking air flow through said outlet end and a position substantially unrestrictive to air flow through said outlet end.
