Where have you seen this used?

Came across a gadget in a box of stuff yesterday whilst searching for something else.
I've had it for over 20 yrs and still don't know where it came from.
Bore is 13/16ths or 0.8125".
Kudos to anyone that can correctly identify it.

Clutch throw-out linkage for a sewing machine motor

 

[fitterman1]

Is that a home or industrial motor?
My initial thoughts were it was for something in metrology.

Paint can sprayer attachment. Or for filling air conditioner pump.

Keep em coming.

Does it have any markings on it?

It's a right handed precipitating canabulator. The left handed version is shown here.





Alright, alright! Sorry, I couldn't help it, I missed April Fool's Day and now I'm making up for it.

It does look amazingly like a throwout bearing fork though.

LOL, All good replies so far, there are no markings whatsoever, it is painted in black crinkle paint. All ally except for adjusting screw and nut and spring.

 

[kd4gij]

It appears to be some type of spring compressor. For what, I have no clue.

I'm guessing an optical lens control device of some sort.
Think old fashioned black/white photographic enlarger.
The finish reminds me of old Kodak cameras.
