I've never seen this kind of outlet. It was in a garage in a 1915 house with knob and tube wiring. Anyone know what it's use is?

It could be a 20 amp 115 v circuit. There were not a lot of standards in them days.

Early on in the scheme of things there were 2 varieties of plugs in use. The one we still use with parallel prongs and a variety(Hubbell, among others) with in-line prongs. Receptacles that would accept either type were around for a few years with most appearing to have been installed in the '30s. These are strictly 15 AMP receptacles for 120 volts (actually 110 or 115 at the time).
