Abstract

An air stream projecting device especially suitable for cooling, heating and ventilating large enclosures by providing both horizontal and vertical control of air streams. The device is usually mounted on the side or end of an air duct and serves as an outlet for the air contained in the duct under pressure. The device includes a rectangular frame in the opening in which a hollow barrel-shaped member is journaled for limited angular movement. One side of the barrel member is opened to the duct to receive air therefrom and the opposite side is opened to discharge air therefrom into the atmosphere of the enclosure. A wall surrounds the discharge opening of the barrel member and projects therefrom beyond the rectangular frame. Carried within the walled opening of the barrel member are a plurality of vanes for directing the discharging air. These vanes are preferably individually pivotally adjustable but may be connected together for joint pivotal movement.

Claims9

Dependent claims

A barrel-type air diffuser for providing both horizontal and vertical controls of air streams including, in combination:

a frame member providing a central rectangularly-shaped opening;
a barrel-shaped member fitting the opening of the frame member with slight clearance with the side and end sections thereof, said barrel member being opened along one side to serve as an air inlet and being opened on the opposite side to serve as an air outlet;
pivot mounts carried by the frame member and connected to the barrel member for providing limited rotation thereof about an axis generally corresponding to that of the barrel member and disposed parallel to the plane of the frame member;
an outlet duct mounted on the barrel member in surrounding relation to the air outlet opening thereof and having the side and end walls thereof projecting outwardly beyond the opening to serve as a nozzle for controlling the direction of the air stream discharged through the outlet opening of the barrel member;
a plurality of similarly formed vanes mounted crosswise in the outlet duct of the barrel member in spaced apart relation to one another for further controlling the direction of the air stream discharged from the outlet duct;
and
said air inlet of the barrel member as well as the interior of the barrel member being free of any obstruction to the flow of air through the barrel member to the outlet duct.

A barrel-type air diffuser for controlling the direction of air streams including, in combination:

a frame member providing a central rectangularly-shaped opening;
a barrel-shaped member substantially fitting the opening of the frame member and having side portions thereof located on opposite sides of the plane of the frame member, the cylindrical wall of said barrel-shaped member being opened along one side portion to serve as an air inlet and being opened on the opposite side portion to serve as an air outlet;
pivot mounts carried by the frame member and connected to the barrel member for providing limited rotation thereof about an axis generally corresponding to that of the barrel member and disposed parallel to the plane of the frame member;
an outlet duct mounted on the barrel member in surrounding relation to the air outlet opening thereof and having its side and end wall sections thereof projecting forwardly beyond the opening to serve as a nozzle for controlling the direction of the air stream discharged through the outlet opening of the barrel member;
a plurality of vanes mounted crosswise in the outlet duct of the barrel member in spaced apart relation to one another and further acting to control the direction of the air stream discharged from the outlet duct, each of said vanes being secured to a pivot rod which has an end portion thereof extending through a side wall of the outlet duct and projecting externally of the duct and forwardly of the curvature of that surface of revolution conforming to the cylindrical wall of the barrel-shaped member;
means operatively associated with the externally projecting end portion of each such pivot rod for releasably locking its associated rod and vane in pivotally adjusted position in the outlet duct;
and
said air inlet of the barrel member as well as the interior of the barrel member being free of any obstruction to the flow of air through the barrel member to the outlet duct.
