Every time I see that beautiful illustration of the Philco Automagic action I wonder exactly how it worked. The agitator looks much more like a Frigidaire Jetcone than a normal agitator, but given how carefully GM protected all their inventions with patents I assume Philco couldn't just copy the Frigidaire action. Was this a Bendix design Philco inherited? How does one of these Automagics work?
