Help identify this odd adjustable clamp-like tool

[JPRI]

Found in a shoe box full of machinist tools, with a bunch of early ones (LS Starrett, DB&S, J.Stevens, etc). I need help on this one.

Jam jar lid remover? Either that or a grostling iron.

Speed handle for a... valve, machine or steering wheel?

I forgot to mention this thing is only @3"L.

 

[partsproduction]

Yeah that thing is nifty.

First gen teeball holder

I'm sure I've seen that - or something very like it,m before,..........but what it was has gone, (it's me age you know ) .......I'm thinking some sort of winding tool, ???????????? possibly sewing, knitting, spinning or cloth making?

Speed handle for a recording reel of some sort? I doubt it's for removal or tightening of anything, as the crank handle isn't suited for that purpose.

It look similar to clamps used to hold Pocket watches.

Looks like the bottom of an old roller skate. Modern version, no skate required!

That was suppose to say "no skate key required". Sorry long day.

Tool for repairing a pull starter with a recoil spring. Holds the spring while you replace the broken rope.

I just made that up

Constipation relief tool.

+1 to Robturner. It looks a bit like a pocket watch movement holder.

I finally identified this thanks to a Martin J. Donnelly past auction email. It's a clamp for a combination safe lock to increase accuracy in turning.

Thanks for the follow up! Now the funky part is that 10 years from now I'll see oe of these things somewhere and I'll say "That is a safe combination lock accuracy handle!" and everyone will think I'm a genius, instead of someone who was screwing around on the internet at midnight when he should be sleeping.

I'm filing that in my bin of useless tools I may construct and use for a different purpose at a later date.
Only reason I can think of for a device like that is applying force to a wheel pack that will probably shear the key and cause a really expensivce repair.
