ABSTRACT:
A cylindrical pivot for a multiblade damper assembly having at least three pivotally mounted blades is provided in which the blades are interlinked by connecting rods pivoted to brackets which are secured to each of the blades. Each bracket is formed with a pair of parallel extension arms which extend beyond an end of the blades, and these arms have opposed openings for receiving a cylindrical pivot at their outer ends. A cylindrical pivot is rotatably mounted in these opposed openings, each pivot having a threaded axial bore at both ends thereof and a cross hole extending therethrough. At least two of these pivots are axially joined together by means of a threaded rod which is preferably constituted by a studded connector having a centrally positioned flange which serves to insure that both pivots are adequately threaded on, and it also serves as a stop when the pivot between the arms of the bracket carries no connecting rod.
