ABSTRACT:
An energy saver automatic temperature responsive vent, for permitting the passage of air from one defined space to another, which includes a frame for mounting over an opening extending from one defined space to another defined space, the frame having a central passage disposed therethrough and a flap movably mounted to the frame, so as to be means, movable from a closed portion substantially blocking the passage to an open portion permitting the flow air therethrough, a temperature drive assembly being provided to open and close the flap in response to changes in temperature. Adjustment means are provided to preclude the flap from closing entirely, if desired. In addition, the vent is configured so that it has a recess disposed therein for accommodating the knob or the like of an adjustment means on a similar vent so that the vents can be nestled together in the most compact space possible as an expedient to shipping.
