## Abstract

A register of a forced air system to include an injector and a damper switch to regulate a thermostatic element for heated and air-conditioned airstreams. A direct drive mechanism to allow the thermostatic element to control the movement of a sliding grill.

## Claims

### Claim 1

A heating and cooling register for admitting forced air into the room from a forced air system, comprising:
a housing, said housing defining a top flanged having an opening disposed generally centrally therein;
a first plurality of elongated ribs extending parallel to each other across said opening and spaced apart from each other to define spaces therebetween, each rib having a bottom edge;
a second plurality of elongated ribs extending parallel to each other and spaced apart from each other to define spaces therebetween; said second elongated ribs being disposed adjacent said bottom edge of the first elongated ribs, means for sliding said second elongated fibs with respect to said first elongated ribs for opening and closing said opening;
said means for sliding including a lever assembly pivotably attached to said second elongated ribs for the movement thereof, said lever assembly being L-shaped with a long arm and a short arm, said lever assembly being pivotably attached to the housing at the junction of the L-shape, and actuating means for moving said second elongated ribs via said lever assembly, said actuating means being a thermostatic element having it plunger for engaging said short arm, said long arm being pivotably attached to said second elongated ribs; and
means for alternatively supplying said forced air, room air, or forced air and room air to said thermostatic whereby the flow of air through said opening is controlled.
