  • Patent number: 8065816
    Abstract: A dryer has complex angled surfaces and a plurality of grip elements thereon. The angled surfaces have varying angles of inclination relative to a base of the dryer vane and the characteristics of the grip elements vary in relation to the angle of inclination of the surface portions upon which they are disposed. The grip elements may protrude from the vane surfaces and the height of the grip elements may vary in relation to the varying angle of inclination of the surfaces. Taller grip elements may be provided on the less inclined surfaces and shorter grip elements may be provided on the more inclined surfaces.

  • Patent number: 7992321
    Abstract: A laundry dryer includes a cylindrical drum shell mounted for rotation on front and rear stationary bulkheads of the dryer. A drive system is configured to rotate the drum in first and second opposite directions. Three rollers are arranged about a lower portion of the drum circumference, on the rear bulkhead, to stably support the rotatable drum during rotation in the first and second directions. The arrangement can also avoid potential flexing and distortion of a cylindrical drum shell of relatively large diameter. In addition, a reversing idler assembly is provided for maintaining proper tension on a drive belt during drum rotation in the two directions. The assembly provides a biased mount for two pulleys on a pair of arms integrally formed with a spring as a single piece, in lieu of separate articulated mounting arms and a separate biasing spring.
