Abstract
452,194. Disc-supported blade fans. SCHEID, A. MITTELSTEN-, (trading as VORWERK & CO.), 23, M³hlenweg, Barmen, Wuppertal, Germany. Feb. 17, 1936, No. 4753. Convention date, March 1, 1935. [Class 110 (i)] [See also Group XXVIII] In a blower for vacuum cleaners, with its air outlet connection c branching off radially or tangentially at an angle x to the plane of rotation of the fan, the vane wheel f or its vanecarrying disc g ascends towards the margin at the same or approximately the same angle of inclination as the air outlet connection. The ascending portion may be conical as shown, or curved or stepped ; the lower edge of the vanes may be radial or may ascend also. The fan f is mounted on the shaft e of motor d which is arranged concentrically or eccentrically in the casing a to form a uniform annular or continuously widening air passage which may extend in the plane of the fan or may ascend helically as described in Specification 419,191.
