Abstract

19,003. Criqui, A. A., and Deventer, J. H. van. Aug. 24. Impeller blades.-In a centrifugal fan of the type shown in Fig. 2, the blades 24 are formed of two sections of cones. Fig. 4 shows a blade having a forward and a backward curve, the blade being concave at the heel 29 and convex at the tip 28. The blade may be made up of two sections of cones joined by an intermediate part. The tip of the blade may be arranged so that the velocity of discharge increases along the blade towards the disk. The blades may be used in double inlet fans.
