Abstract: A dispenser apparatus for holding, dispensing, and severing lengths of flexible duct connector material from side-by-side coils thereof includes a guide station and a cut-off station shiftable laterally of the apparatus and into alignment with a selected one of the coils. The coils are supported on an anti-friction cradle which includes anti-friction rollers extending laterally of the device, the ends of the rollers being supported on chains hung in catenary fashion. Since the rollers are capable of moving toward and away from each other, they are free to define a cradle which conforms to the periphery of the specific coil which is being fed to assure that the connector material may be withdrawn for processing with the lowest possible force.

Abstract: An actuator assembly for a multi-blade damper includes a base plate having slots extending longitudinally thereof and slidably receiving drive portions of the louver shafts. A series of drive slots extending generally perpendicular to the clearance slots is formed at each side of the clearance slots. A series of link assemblies are keyed to the shafts, the link assemblies including actuator pins extending into selected ones of the drive slots. A clamp connection interposed between the link and drive portion of the louvers permits relative adjustment of the link relative to the louver. Movement of the base plate parallel to the plane defined by the axes of the louvers results in tilting of the louvers in a selected direction, dependent upon which of the series of drive slots is occupied by a pin of a respective link.
