Abstract

719,967. Axial-flow blowers. NORDISK VENTILATOR CO., AKTIESELSKAB. June 3, 1952 [June 4, 1951], No. 13985/52. Class 110(1) In an impeller for axial-flow blowers and the like, having impeller blades each adjustably rotatable about its longitudinal axis, each blade is provided with a weight for approximately balancing the turning moment about the axis due to centrifugal force acting on the blade, the weight being disposed within the outer surface of the impeller hub. In the construction shown in Fig. 3, balancing weights 10 are carried by arms 11 projecting from the root pin 9 of each impeller blade 7. In a modification, the weights 10 are attached to the root plate 8.
