Some help from my friends

[ex_nihilo]

Hi Everybody,

I recently acquired a couple of small items that I don't know exactly what they are for.

The larger of the two collet looking pieces is marked "Craftsman" with no other markings. The smaller one has no markings at all.

Neither of the other two have any markings at all. I can provide measurements or thread pitch if those are helpful.

Thanks a lot.

Middle one looks like a type of swivel

Definitely is a swivel, a double swivel but it's not threaded on either end. I have no idea the use.

That swivel looks like it might be for the release shaft on a floor jack.

Third one looks like it could be a plumbing Valve seat restorer. Hard to tell from the pic. How big is the second one could be a steering column couple.

If the third item has a 1/4" shank it may be a cut off wheel mandrel with inserts for different size center holes. The second item could be a auto steering shaft coupler

It is 1/4" shank and the ID of the inserts as well.

It looks very similar to the swivel on my 2 ton floor jack. Except of course this piece has 2 u-joint connections whereas the release shaft swivel on my floor jack only has 1. I didn't measure them but they are pretty close in size.
