Abstract
Abstract A header assembly is adapted to be mounted on top of a partition wall and connected to an air outlet opening in a suspended ceiling system. The header has air divider means which will direct air to either side of the partition. The air divider is a simple X-shaped air deflector which alternately directs air to either side of the X-shape.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
156 words
A header assembly for dividing conditioned air from an elongated air outlet duct to two sides of a room partition wall disposed beneath the duct comprising, a box-like header structure which is positioned on top of the partition wall and which has an air inlet opening in its upper side for receiving conditioned air from the elongated duct, within the header structure there is positioned a geneally X-shaped air divider means which along its length will alternately direct air to either side of the air divider and out of openings on the side wall of the header structure, said air divider means is composed of two pieces of material which have at their upper edges alternate tab and slot structures which will mesh together to hold the two pieces of material in an X configuration with the taBs of one piece of material being inserted into the notch structure of the interlocking second piece of material.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
82 words
The header assembly of claim 1 wherein the box-like header structure has two side walls containing the openings through which air passes after being directed by the air divider, ssaid air divider being placed within the box-like header with the lower edges of the two pieces of material forming the air divider being positioned within the header structure with the bottom of the to pieces of the air divider being placed adjacent the bottom fo the side wall of the header structure.
Claim 4
Dependent Claim
100 words
The header assembly of claim 2 wherein the upper edges of the two pieces of material forming the air divider have a plurality of alternate tab and slot structures which mesh together to hold the two pieces of material in the X configuration, said tabs are positioned closely adjacent the air inlet opening of the header structure and the tabs direct the inlet air towards either side of the header structure, while the lower portion of the two pieces of material forming the air divider directs the air out of the openings on the side walls of the header structure.
