Abstract
953,057. Mounting electric motors. ELECTROLUX A.B. April 26, 1960 [April 27, 1959], No. 14558/60. Heading H2A. [Also in Division F2] A suspension device for supporting a rotary device, e.g. a fan or vacuum cleaner motor, comprises at least one elastic ring having eight or more radial projections, the radial dimensions of which are greater than the greatest circumferential dimension. As shown, a fan 11 is supported within a casing 12 by an elastic ring 10. The projections may be directed radially outwardly or inwardly and may be tapered or have concave sides. The ends of the projections may be flat, pointed, concave or convex. Two axially spaced rings of projections may be provided.
