At one time, wall-mounted 'receptacles' for serving portable appliances had traditional edison-base screw shells. You could literally screw a lamp into a wall-mounted receptacle. The one I have seen in an older house had a brass, hinged cover to save unintentionally contacting live conductors.
Has anyone else seen an old (Disney???) cartoon where a cat-and-mouse chase is going on; the mouse of course runs into the baseboard mouse hole and the cat heads right into an UNCOVERED Edison-base receptacle in the baseboard!
Ya gotta wonder how many babies were shocked/electrocuted with those...
Oops, sorry for the threadjack!
