ABSTRACT:
An improved clothes dryer construction including a metal dryer drum, front and rear bulkheads, front and rear wear rings, and a plurality of wear pins. The dryer drum is generally cylindrical and provides front and rear annular lips over which the wear rings are mounted and which coaxially nests over a support ring provided by each of the bulkheads. The wear rings, which seal the space between the lips and the support rings, have a series of openings which align with apertures in the annular lips. The wear pins extend through the openings in the wear rings and are snap-fit into the apertures to secure the wear rings to the annular lips. The wear pins serve as a supplemental bearing to support the dryer drum should the wear rings wear out over time.
