Virgie M. Ammons of Eglon, West Virginia
"Inside the fireplace chimney is a device called a
"Damper". The damper is opened and closed to
allow smoke from the fireplace to be drawn upward
out of the house. The "Fireplace Damper Actuating
Tool" designed by Ammons allows the damper to be
"locked" in the closed position, preventing cold
air and dust from blowing down the chimney back
into the house."
