Abstract
Abstract A hot air register of the type that includes a vertically baffled front piece that is secured to a wall in communication with the outlet of a hot air duct therein. The front piece has a resilient sealing strap disposed between the rearward peripheral surface thereof and the wall. A plurality of horizontally disposed louvers that are pivotally adjustable in unison are supported in a rigid sheet frame that extends rearwardly from the front piece into said duct. The rearward portions of said frame are formed to flare outwardly towards the interior surface of said duct but do not contact the same. A slotted resilient member engages the rearward extremities of said frame and is also in sealing contact with the interior surface of said duct. The resilient strip, frame, resilient member and a portion of the interior surface of said duct cooperate to define a dead space into which soot and dust are discharged by the hot air, and which soot or dust would otherwise be discharged laterally relative to said front piece to discolor the wall adjacent to said register.
