Ice Maker:
That is an early Auto-Fill unit; the name was later changed to Ice 'n Easy.
It's not exactly an icemaker in the sense we think of one today. The tray was filled automatically, but you had to dump the tray by picking up the right side of the tray and flipping it over to the left, so that the ice ended up in the bin on the left.
So- more semi-automatic than automatic. It was a great device in its day, though.
