Is there a tool, what is it called, that works the opposite of a
vice. Something to put between two boards and apply some force
outward to help separate them. I am thinking of space distances of a
few inches to almost a foot if possible.

Not sure what application you had in mind, but many clamps permit turning
the heads for outward pressure.
