ABSTRACT:
A mounting pin for a pivoted damper blade is disclosed which comprises a cylindrical shaft having a cenrtrally positioned hole extending therethrough, this hole being surrounded on one side of the pin with an upstanding flat seat. This hole is longer than it is wide so that it extends longitudinally of the pin. Also, the pin at one side of the seat is formed to include longitudinal depressions which provide a plurality of circumferentially spaced arc segments which form an interrupted circle. This pin is mounted on a blade at a side margin thereof by means of a bolt extending through a hole in the blade and through the hole in the pin, and a nut is associated with the bolt, the nut locking against the flat seat of the pin. A resilient gasket is interposed between the head of the bolt and the rear face of the blade so that the bolt need not be held while the nut is tightened. Also, a locking washer is desirably interposed between the nut and the seat.
