Seems that these crowfoot connectors have existed as far back as 1916, as seen at the US Patent office http://patft.uspto.gov/netahtml/PTO/srchnum.htm, look for patent number 1179728 (type this number in the search box, and on the next screen click "images" and look at figures 3 and 4.

Wow,
That's an interesting find!

I have somewhat of a problem with running an electric fry-pan off of what looks like a lighting circuit though. whistle

Back in 1916, that (light socket) was the only source of power in a lot of houses, at least those that even had electricity.
