Abstract

1,048,364. Centrifugal and centripetal fans. ROTRON MANUFACTURING CO. Inc. Feb. 5, 1965 [June 26, 1964], No. 5123/65. Heading F1C. [Also in Division E2] An impeller comprises an annular series of vanes fixed, each by one edge, to a carrier member, and an annular member extending around the opposite edges of the vanes, the annular member being held by at least two tabs projecting from the edges of at least two opposite vanes, the tabs fitting in slots in the annular member, and the tabs and slots having angularly related edges in interfering relation co-operating to urge the annular member against the vanes. A centrifugal or centripetal fan impeller formed from plastics material or metal, comprises vanes 46, Fig. 2, integral with a back plate 44. A shroud 52 is formed with slots 56 for engagement by tabs 54 formed on the vanes 46. As shown in Fig. 4, the edge 56a of each slot 56 lies in a plane X-X parallel to the impeller axis, while the edge 54a of each tab 54 lies in a plane Y-Y disposed at an angle to the plane X-X. The edges 54a and 56a have an interference fit whereby the sharp outer corner 56b of edge 56a bites into the edge 54a to retain the shroud 52 in place. Additionally, the ends of the tabs 54 may be heated and caulked over. Impeller vanes may be connected to a back plate in the same way. A cover 18 is pushed into the back plate 44 with its three tabs 20, 21, 22 passing through slots 23, 24, 25. It is then twisted, by inserting a tool into recesses 29, 30, 31, until detents 26, 27, 28 snap into position. The impeller may be of centripetal type.
