1928 vintage receptacle

[AHI in AR]

I vaguely remember seeing something like this show up once before here but I've slept since then. Today's 1928 home had several of these still in place. Company name on the front was Rodale. What's with the two slots opposite each other horizontally? Yes, there was power to these.

Thanks Bill. After seeing that the post discussing these things was over 5 years old I don't feel so bad for not remembering what it was.

Yeah but you forgot last year when we discussed them again. []

In a modern setting, the flat slots are likely to be for a 240 v circuit like a 30 amp for a compressor. Old house, 120 vac.
