Any ideas as to what it is or used for??

Guy dropped this tool off at the shop and said that I may be able to use it.
I have no clue as to what it is or used for. First thought was for installing valve seals. But honestly have no clue.

I have one of those, a "universal" valve spring compressor for overhead cam engines. Used it once or twice.

Thank you gentlemen. And thank you Wore Out for the photo.
Never saw a compressor like it. It was given to me so it will go into the special tools cabinet. May never have to use it. But will be there should the need ever arise.
 
Looks like a rube goldburg arrangement for that job. The one we have would work for valve in head engines also if there is enough room to get the keepers off the stem. Ours looks sort of like a C0clamp with a push bar like an arbor press that holds the valve head as it squeezes the spring to release the keepers. Even has a lock so you can use both hands if needed.
 
Mule Meat,

Talking about reinventing the wheel. Yes it is a tool to install valve seals. Mime is
a lot simpler and user friendly one size fits all!

It depresses and cages the spring, you know the rest,

I suppose it would be handy on 3, 4 valve per cylinder heads. Or DOHV. Go from one to the next quicker than using the C clamp type compressors that I am use to.

Guess what threw me off as it being a compressor. Is the fact that when you compress the spring. They're nothing to hold the valve closed in the dome or against the seat.

There are situations where such a rube Goldberg set up is the only way the get the valve springs off to disassemble the head.
(Small valves in tight places.)
I also have the g-clamp compressor and used it when the head was off the engine, and two styles of the bent, flat, forked bar, when the head was still on the engine.
When the "assembled" head is on the engine and there is adequate room, I have a more compact rube Goldberg device with special fingers and compressing screw for overhead cam engines.
There is also a different G-clamp setup for valve springs that are recessed in the head.
The G-clamp is the old standard and has it's place but some jobs require that "special tool".
I have made one off adapters to use with the G-clamp in desperate circumstances but when push came to shove I bought the right tool for the job.
Still have the rube Goldberg tool for flat heads.
I feel an urge to take a pic now, Tomorrow.
So many tools I don't use anymore.
 
My kit has adapters to install in spark plug hole or diesel injector port.
You pressure up the cylinder when the head is on the engine to hold valves closed, then replace valve guide seals.

Ever have some fool mess with a valve while you had the cylinder aired up and have to remove the head to get the valve out?

Been there and done that twice in my life time... 🤬🤬

I came very close a few times but didnt drop it all the way. Lucky.
Here's a tool pic with some extra tools for the old timers.
Missing one flat bar tool,might have loaned it out.
