Every company was innovative in their own way, Frigidaire had their pulsator agitator, Kelvinator had their agitation which reminds me of a mixer, Apex had their bouncing basket, Whirlpool was the first to make a perforated tub from the very beginning in a top loading design and had many innovations throughout the 50’s and 60’s, GE used a clutch that allowed the machine to filter out since the motor ran at full speed while the clutch allowed gentle agitation which helped filter out lint, Maytag introduced moisture sensors around 1959/1960. GE, Frigidaire, and Speed Queen had foot pedals on their dryers which allowed you to easily open the door when your hands were full. I could list more, but this is what’s on my mind at the moment and will post more later if anything else pops into my mind later.
