975. Pharmacists pill roller.
976. I think they're for making beads or grooves in wood.The name
riffler comes to mind but I don't think it's correct. Here's a similar
tool for inletting rifle barrels.
They're usually called a "float". Plane makers (wooden joiner's
planes) used them for making the cross-grain grooves for the iron-
holding wedges in plane bodies.
They're also used for insetting barrels and actions into gunstocks.

971) I've never seen anything like this before, but it looks
to me like a hinge designed for quick replacement of
whatever is held between the claw-equipped fingers.
At a guess, it is for something like the striped barrier board
at railroad crossings or something similar. Those must get
broken fairly often, and being able to replace them quickly must
be an advantage. The four conical projections must be for
establishing proper alignment before bolting the hinge in place.
The 'V' notch in the hinge suggests that it is designed to stay
in a single position normally (with a matching projection in the
mating part), and the spring is for returning it to the proper
position after it has been pushed past -- assuming that the
board did not break.
972) A folding symbol of the USSR? :-)
I guess that it is for disassembly of crates or something of the
973) Are those steel or cast iron? No real idea what their function
is. You've got a good set of puzzlers this week.
974) I don't think that it is a "gauge" of any sort. Just some sort
of hand-advanced counter.
975) Perhaps for forming cigars or some similar tobacco product?
976) For forming tongue-and-groove joints in wood?
