Only one of them (the center one) is a clip, to keep it closed
when not in use.
The other two are link arms which pivot on the main base and the
narrower part beside it, allowing it to move out from the side while
retaining a state of being parallel to the main one. (The four parts
form a parallelogram.)
Posting from Rec.crafts.metalworking as always.
2497) I first have to ask a question: Does the metal
part pivot around the pin near the large end, and stick out the
small end? If so, I would need to see what that small end
looks like extended.
However, if it does not (I think that there is a smaller pin to
prevent that), I could see this being used as a wrench for
square-headed screws such as are common on lathes. The metal
can take the wear, the large rivet gives it strength to avoid
spreading, and the wood makes a more comfortable handle than the
forged metal wrenches for the purpose would have.
2498) It looks like the top piece is a Fresnel lens, so it could be
used to focus sunlight onto something held in the center of the
bowl. Perhaps to light a cigarette or a tobacco pipe's contents?
But the green glass would absorb a lot of the heat out of the
So a second option might be a disassembled high voltage
Is that some form of tape on the elbow in the third photo?
And is that a loop of wire sticking through it, or a marking on
2499) If the points were not so sharp and long, I might consider this to
be some form of shuttle for weaving. The yarn could be wound
around between the projecting horns on the first one, and
perhaps the second one had similar horns which were somewhat
As it is -- perhaps for gigging fish? (But there should be a
barb on the pints for that.)
2500) This looks like a tool for forcing a cork into (or back into)
a wine bottle.
2501) Hmm ... the ridges in the center hole look as though they would
be good to grip a ribbed bottle cap of a certain size, and some
of the lips appear to be reasonable for lifting press-on caps
for something like a jam jar. Not too sure about anything else.
2502) A rule for use on a chart table -- to sight though it to a
landmark, and the upper edge of the rule (if unlocked in the
center) would turn it into a parallel rule, for drawing a line
parallel to another or to the sighting.
Anyway, for navigating or surveying.
Now to post and then see what others have suggested.

Another guess, it reminds me of the lever used on recliners to move the
I tried searching on/for that idea, but couldn't come up with anything
solid. Some examples, like this newer patent shows that a square shaft
is sometimes used in the mechanism:
It appears to be old though, not sure when they started making
recliners that used a side-arm mechanism like in that patent...
