We had two in different homes....
Where I grew up in Denver we had a two story house. In the hallways was a white square panel, with rounded corners, that stood out from the wall about 1/2 inch. The door in the panel was circular, hinged at the top and closed by its own weight. When you pushed clothes into it, they went downstairs to the laundry area. This house had a very interesting laundry area, you opened closet type folding doors in the "nook" and there was space for a washer and dryer. To the left was a two door cabinet. If you opened the door, there were the clothes from upstairs.
It was a mixed bagged dealing with it, as you kind of had to pull clothes out as more tumbled down on top of you! But it was cool.
When we moved to Illinois for a short time, we had a two story condo with a basement. The laundry was in the basement. There was a wooden door that opened in the hallway upstairs, and this was the laundry shoot. It went all the way down into the basement, where it just jutted out from the ceiling. In that one, you put a laundry basket under it to catch the clothes.
I had hours of fun lowering GI Joes down through that chute to the "planet's surface".
