ABSTRACT:
A low-cost internal lint screen assembly is removably mounted on a rear bulkhead of an automatic clothes dryer in an aperture through which air and lint are exhausted from the rotating drum. A plurality of locking tabs with outwardly-extending shoulders about a peripheral rim of a cover of the assembly flexibly engage surfaces of the bulkhead. Two of the locking tabs are compound tabs also having inwardly-projecting barbs which capture a flexible rim of the frame of the lint filter, the filter frame being compressed inwardly to release the filter from the cover. Also, two of the non-compound tabs may be spring metal attached to the rim, or plastic and formed integrally with the rim material.
