Abstract

614,074. Screw fans. COLLINS, A. L. July 2, 1946, No. 19714. [Class 110 (i)] A fan has each blade 4 constructed as a separate unit of resilient material with a plain unflanged inner end, the inner ends of the blades being clamped between two annular or disclike clamping members 2, 3 having complementarily shaped interengaging surfaces 15, 16 adapted frictionally to hold the blade ends therebetween, said clamping members serving as or being attached to the hub of the fanblade assembly. The blades may flex during the operation of the fan, to reduce the helix angle at the tip in such a manner that the air displaced is of uniform velocity at all points along the blade. The fan blades may be formed by extruding the resilient material with the desired cross-section.
