Hi Guto, welcome to the club, it's nice to see some more Brazilian members! Solid tub washers as well as perforated tub top loading washer were introduced around the same time. Quite a few brands of solid tub washers were introduced in 1947 and in 1948 Whirlpool introduced their neutral draining perforated tub design. The Blackstone automatic washer, initially introduced in 1941, was a solid tub machine, but at the same time had a neutral drain system. There was a big hole in the center of the stainless steel wash tub under the agitator. The tub sat on a rubber disk to seal the wash tub, when drain was called for by the timer the wash tub was lifted off of the rubber seal and the water would drain through the holes in the agitator down the center and out into the outer tub. In 1956 Maytag introduced their new perforated tub with a "spin-drain", the first perforated tub washer that drained and spun at the same time. | ||

Thanks, By the way, I have the impression that the spin drain helps in keeping the load balanced at the beggining of spin (low speeds) even if one´s load is composed of only one heavy item. Is that true ? Was this a reason for manufactures choose this sistem? | ||

Question for Unimatic 1140 Were the very first Frigidaire "Unimatics" perforated tub? I seem to remember something from way back then about that. I assume they would have a spin and drain, but I can't recall actually watching one. I do remember by the late '40s the solid-tub and I remember watching them. -Steve | ||

1947 Frigidaire
Yes the 1947 and 1948 Frigidaire Unimatics had a double spin tub, the inner liner was perforated and the outer shell was solid. This still operates like solid tub washer, even though it looks perforated. The washer spins both tubs to throw the water out into the cabinet. You can see the double tubs and the water filling between the two in this picture...

The water currents in this particular Frigidaire look very powerful.That must be some splash fest. | ||
