I was told by my grandma that there were things called wim-wams which were used for winding the sun up and down and which were kept on the side of the road just for that purpose. I've realised (only recently) that a wim-wam turned up every time Grandma saw a piece of farm machinery she didn't recognise. I expect there's a lot more of them now.
