Abstract

686,666. Pivoted flap dampers. MICHAELIS, K. March 14, 1950 [Dec. 22, 1948], No. 32327/48. Class 137 The air flow through a ventilating duc is controlled by a damper consisting of pair of blades mounted, to pivot on an axi extending across the duct and moved to gether or apart by an adjustable cam so that the duct is gradually opened or closed a return spring imparting movement to the blades in the opposite direction. A num ber of cam devices for actuating the dam pers are described. For example, in Fig 3, two blades 12, 13 are hinged to a shaf 10 secured across the ventilating duct 11 In the fully open position the blades are pressed together by a spring 17. To close the duct. the blades are separated by a wedge shaped member 32 which is advanced between them by turning a screw 18 in a threaded hole in the member, the rotation of which is prevented by its ends engaging in guides 16. In another form. Fig. 6. the damper blades 12, 13. are folded together unwardly in the open position, by rollers 51 which engage cams 53 attached to each blade, the rollers being advanced by turning a screw 35. Air discharging from the duct is diffused by a nested cone distributer 30.
