I'm hoping someone can help identify this item! The green part is cast iron, the rollers are wood and there's a tin plate on the underside. The top part (on the left side here) looks like it should hold some type of a dowel.
Look at the nasty teeth on this thing!
It says Patent May 14, 1918 on one side. On the other side is a raised up star and it says No. 5 under that.
