Abstract

1296762 Centrifugal fans RUSKIN Mfg CO 3 April 1970 [1 May 1969] 15816/70 Heading F1C [Also in Division F4] In a damper for a fan or a conduit, comprising vanes 36, Fig.2, pivotally mounted on shafts 30 extending radially across the damper opening, a flat spring operating arm 38, Fig.4, projecting from each shaft and deflectable longitudinally of the shaft is pivotally coupled by a ball joint 44 to a rigid ring 42 encircling the damper opening, whereby rotation of one of the shafts, e.g. by an electric motor or a solenoid, rotates the ring to cause simultaneous rotation of the remaining shafts. Where two dampers are provided, one for each inlet of a double-inlet fan, they may be coupled by means of a flexible cable 70 connecting one shaft of one damper with one shaft of the other damper.
