Abstract
851,643. Centrifugal fans. TORNADO A.G. Oct. 21, 1958 [July 15, 1958], No. 33642/58. Class 110 (1). [Also in Group XXVIII] Prevention of passage of relatively large airborne particles, e.g. “-inch pebbles 15, 16, through the fan chamber of a suction cleaner, wherein the fan comprises spaced blades 10 projecting from a conical plate 7, is effected by so arranging the spacing b, Fig. 2 (not shown), of the blades 10 adjacent a rim 14 of the inner end of the suction duct 2 together with the diameter of the plate hub and the profiling of that part of each blade near the rim 14 as to provide particle obturating means. The duct 2 is inclined to the fan axis 11 and one side of the rim is beaded at 12 whereas the opposite side is chamfered at 13.
