Used for a wall clock, back in the day.
Here is a modern version - you can see the little hanger hook at the top of the face plate.
It's called a clock box, the outlet is slightly recessed so the clock can lay flat against the wall and still be plug in.
Edit:
Does it look like this?

Edit 2: the little metal piece is so the clock has something to hang on.

It's a rule that requires fridges to have a dedicated circuit (and off the kitchen small appliance circuits). The exception allows you to power a clock off the same circuit. It's actually advantageous since mains clocks would stop with power loss, thus you could compare the kitchen clock against a correctly set clock. Subtracting the kitchen time from the correct time would tell you how long the fridge was without power.
