I have forgotten what it was called but i think it was a mangle: Two long rubber rollers on a stand with a handle that was used to wring out wet sheets after washing.
This was either late 1950s or early 1960s. I remember it well, and the warnings to keep my fingers out of it so they didn't get squashed by the rollers!
If we think women's work is hard now, it was even worse then.
