265751 Don Schwartz <dks@t...> 2018‑04‑22 a curious clamp
Jim Bode has sold a group of small clamps - said to be instrument 
makers' clamps. Three are typical small wooden clamps. But the fourth is 
an odd duck AFAIC, for two reasons I guess.

1. I can't figure out how it works, and

2. I can't see what it might be used for.

It seems that one of the screws , on the right side in the photo, might 
be used to mount the clamp onto something while the other is being put 
to work, but again, I don't see how. It seems like there should be a 
pivot point in there somewhere, but I can't see one.

Anyone have any ideas, or seen another like it?

Don, who finally got his CDs all shelved!

3 of them are pretty standard screw clamps - not really used on instruments that
I know of.  I don’t recognize the 4th, but it is 2 clamps in one.  I can’t
imagine what you would be clamping if both sides of the clamp are used at once.

It looks a bit like a vise. One screw to mount the clamp, the other to 
do real work. But what? General purpose or a specialty item?

Imagine the laboratory of Dr Frankenstein.  Apparatus held upright and clamped
with one arm around the vertical support rod, and the other clamp to hold the
test tube…


Hahaaahaha ! 
(wait for the lightning) 

Or,more prosaically,  a round bench dog being held tight, and a ‘something’ you
need to work on being held in the open end.

Or…  


Such a useful and elegant solution to someone’s clamping problems.

There is a small spot on the straight-ish (left side) part, about half way along
the length.I strongly suspect that there is a steel (or brass) pin-- maybe a
nail-- through there a a pivot, with a metal tongue inside.


As to purpose, I agree that is is for attaching to a round rod and holding
something else. Not likely a lab clamp, unless for real specialty like
explosives. Too many common chemicals turn wood to waste quickly. Maybe a clamp
for stretching skins?

Quilters & cros stitchers have a variety of clamps… but a Google of     quilt
clamp imaies diid not show one o these.

As I read it, the left screw allows the clamp to be fastened to a pipe, 
and the right screw holds the workpiece in place. Alternatively, the 
right screw attaches the clamp to a (thin) table or plank, and the left 
screw holds a pipe or other cylindrical object to be held in place.  
Whichever, the orientation of cylinder and plank are fixed - no pivot.  
Just can't think of anything like that.
