Abstract

496,984. Centrifugal fans. ANDERSON, E. L. Feb. 18, 1938, No. 5116. Convention date, Oct. 6, 1937. [Class 110 (i)] In a centrifugal fan with a plurality of inlet vanes 23, each vane has a radial leading edge 29 and a non-radial leaving edge 30. The air inlet opening has two cones 13, 15 of different angles leading to a part 14 parallel to the shaft 22. The inner end of the inlet has a flaring section 16 overlapping the shroud 17 of the blades 19. Each vane is turned at the axle end at right-angles, as at 24, to lie against the sleeve 26 where it is supported by a strip 27. The edge 29 has cut-offs 32, 33. The fan is mounted in a scroll casing that is not a true volute.
