Help! What are these?

Can anyone help me out with this? I am cleaning out a workshop and found these. What are they? Any help would be appreciated. Thanks.

It's hard to see in the first pic but the two knobs on the ends actually are for tightening the clamps on the bottom. So it clamps on to something just don't know what. That square block also slides along the rail. It's all iron.

Thanks for the pipe clamp !!!

Top one looks like it should clamp to the side of a door and then the sliding block is used to guide a drill when you are drilling out for a mortice lock. Like this one

Second pipe vice.
