Abstract

6700. Mulholland, W. March 17. Shallow-overhung-blade centrifugal fans; impeller blades.-In a centrifugal fan or blower of the type having shallow blades arranged so that the spaces between adjacent blades taper outwards, the inner edges a<1>, Fig. 1, of the blades are curved forwards in the direction of rotation. The backs a<3> of the blades are so shaped and arranged relatively to the faces a<2> of the succeeding blades as to form outwardly-tapering passages f between the blades with the outer ports f<1> of the passages f in advance of the inner ports f<2> in the direction of rotation. The blades are arranged tangentially to the axle e, and are shaped somewhat segmentally as shown in Figs. 1 and 3, or made with a secondary blade a<3> on the back of the blade a<2>. The blades may be formed with a straight tangential part a<4>, Fig. 3.
