In an auction I recently won was an old tool I vaguely remembered:



Doing a bit of research I found out it was Cox puller/press. I can kinda see how to use it as a press, but I don't see how to use it as a puller:



I’ve got a vintage pinion puller and the Ninco puller/press. It’s obvious how to use those. But this one, I’m stumped. Can someone post a picture of it in use?
Thanks,
Ron
