Have CR Buying Guides 1950-1958
Then as now CR didn't test everything each year and often just referred to last test done prior.
In 1953 CR ranked Maytag's E2LP as best of "non-automatic" washing machines tested in 1950. However CR noted it was also the most dear in cost. Next down in rankings for "good" were the Norge CW-22-PT, and Apex 835P.
Looking at the 1950 test results for "non-automatic" washers as noted Maytag E2LP
was the sole entry for acceptable-excellent.
Acceptable - Good were:
Norge
Apex
Speed Queen 648P
According to CR primary emphasis was on washing efficiency, as measured by whiteness of specially soiled cloths after they had been washed for ten minutes under uniform conditions. The rest were quibbles about structural and or mechanical issues, durability testing, efficiency of wringers, speed and convenience of wringers, ease of cleaning, etc.
The Easy 501 was rated "Not Acceptable". Due to excessive force to operate wringer safety release; also clothes had a tendency to be caught and abraded or torn under agitator.
CR didn't test "non-automatic" washers again in the 1950's from what one can see.
Issues just keep referring back to the 1950's testing.
This could be for several reasons. First and foremost we know CR had a hate towards wringers that built up during post war years. By 1950 and certainly by middle of decade more and more space was devoted to fully automatic and or semi-automatic washing machine reviews. During this period many appliance makers also began dropping conventional wringer washers from their line-up, that is if they didn't go out of business themselves all together.
CRs tests bore out what housewives and others long knew; square tub Maytags out washed anything else on the market, even their round tub models.
To get a really accurate view of wringer washers you'd probably have to consult the 1947 editions which were the last time prior to 1950 CR did a major testing.
Ironers were also last tested in 1950 as well; and by middle of decade nearly all references to them is gone. OTOH you got more space devoted to automatic tumble dryers. This again jives with what many of us already knew; tumble dryers largely replaced the need for all that ironing after wash day. What was left such as men's dress shirts were often just sent out.
As for Maytag conventional washers not have a filter; that isn't true. Firstly Maytag out of the box invented their patented "sediment" zone which helped keep water clean of muck. However by the late 1950's or sometime in 1960's you could get that black agitator with a lint filter/detergent dispenser, same as in Maytag automatic washers.
IIRC Whirlpool and *maybe* a few others late in game came out with two speed wringer washers. Largely to compete against fully automatics I shouldn't wonder. However consider the Maytag "gyrofoam" wash action was quite gentle and efficient. Under loading and using a short cycle time would have been gentle enough for most things.
Yes, the Visimatic open top mangle was something new and so forth for wringer washers. But if one followed Maytag's hints and or built up experience things being wound around wringer weren't always a huge deal. Remembering to have things wet, turning a bit of the edge under before feeding into wringer, spreading out the load along length of wringer...
Consumer Reports did test wringers again in early 1960's IIRC. Cover title was "Wringers, Are They Still Unsafe" or some such. Guess this was targeted at the few non-automatic washers still being sold (Maytag, SQ, Montgomery Wards, Easy,)
