This is a clamp used in chemistry labs.  The typical setup stand is
simply a steel rod on a base.  One side of the clamp attaches to
such a stand and a rod fitted to the other side, with any of a
number of gizmos for holding stuff attached to the rod.

It would actually be quite handy to have a some of these clamps and
some steel rod (1/4" I think) in your shop.
