I mean really consider it. A swimming pool doesn't have a lip overwhich leaves and junk flow to skim off the scum. It has a little box in one corner into which flow is removed, all the scum flows to the box.
So add a skimmer box to the outer tub to enable overflow rinse action on a perforated tub washer. Put it in the corner/s where there's room. Or just poke holes in the outer tub and attach elbow plumbing fittings with gaskets to make a drain. Either system will drain/skim off the top gook for the overflow rinse feature.
For the bold, add a variable freq drive which kicks in after spin is up to speed, say set it to 90 hz, that would change 800 rpm spin to 1200 rpm.
Result, frigidaire 1-18 (or whatever) with >1000rpm spin and overflowing rinse.
Am I nuts? Perhaps, I was up late reading the history of the rollermatic. I couldn't put it down. Thanks again unimatic1140.
Any one have a grey scale scan of that document, or pics of the pictorials? e.g. in fig 2, 4 , 8 the details wash out. Those engineers sure had some ideas, I wonder if there were 2 or three engineers working on this over the years. 20-25deg roller pressure angle, spin wheel clutch brake assy, agitate shaft flex coupling, agitate arm with ball joint....there's a lot of room for problems as things wear and loosen up. I'd expect the neophrene to degrade after 20 years.
