Hotpoint's GE Evolution
Even though Hotpoint was part of GE since probably the 50's, it appears that they were built their own way, then gradually evolved to become pure GE by the late 70's.
I've seen YouTube videos of early Hotpoints which had a one-way drive (agitation goes right into spin without pause) as opposed to GE's reversing drive (motor & tranny pause and reverse for spin). When GE switched to perforated tubs sometime in the 60's (I think), Hotpoint held on to solid tubs until the 70's. I read in a past thread that Hotpoint restyled their tranny numerous times until settling on the GE tranny in or just before the 70's. (Could someone give me details about the trannys they used, and how they worked?) The early 70's appeared to be the last somewhat "pure" Hotpoints. They were mechanically GE, but had a filter ring instead of GE's agitator mounted basket, and a different agitator. By the late 70's, they were pure GE.
As for the dryers, the early Hotpoints, I understand, had the downdraft air flow, with the heat source above the drum, and a pullout filter below. I don't know whether or not this was actually a continuation of the first GE dryers. (Could someone clue me in on that?) I saw ads of Hotpoint dryers from the early 60's, and they appeared mechanically identical to GE, but with a different exterior. I believe this style continued until the late 70's, when they became pure GE.
Correct me if I'm wrong, as I really would love to learn the true history and evolution of Hotpoint (as well as many other makes).
