Early Westinghouse Dryer Lint Filters
Weather the lint collected on the outside or in the case of the later style the lint collected in the bag it was a mess to clean and since this area was pressurized lint would leak along with hot moist air around the little door. It is easy to see why WH completely redesigned their dryers in 1964 and basically copied GEs successful design.
The earlier slant dryers did have their advantages however, bigger drum, easier to load and unload and fairly good durability in the early models with the motor mounted fan and front drum support rollers. Unfortunately when they lost the front support rollers and added a belt driven blower they were not very durable or long lived dryers.
