Abstract
702,084. Centrifugal fans. CARRIER CORPORATION. Sept. 7, 1951 [Oct. 14, 1950], No. 21177/51. Class 110 (1). [Also in Group XXIV] An impeller for a centrifugal fan comprises two similar discs 11, Figs. 1 and 2, mounted on a shaft 8, each disc carrying fastening members 16 Figs. 3 and 4, the members on one disc being oppositely directed to those on the other, the discs being relatively rotated from the position shown in Fig. 3 to that shown in Fig. 4 so that the members pass through openings 7<SP>1</SP> in impeller vanes 7 and restrain the vanes against radial movement, and end rings 10 being secured to the opposite ends of the vanes. The members 16 are of hook-like form, each comprising a root 17 and a tooth 18, the lower edge 18' being inclined so as to force the vane inwards towards the shaft. The side wall 20 of the roots 17 clamp the vanes, as shown in Fig. 4, when the impeller is assembled. The discs 11 may then be riveted together. Preferably, tabs 9 on the vanes extend through holes in the rings 10 and are welded thereto. Alternatively, the tabs may be omitted and the vanes brazed to the rings. Each disc 11 comprises a radially extending periphery 14, a conical part 12 and a hub part 13 which is clamped to the shaft 8 by two members 22, 23 drawn together by bolts 30. Preferably, tabs 15 on the hubs 13 extend through holes in the members 22, 23.
