They look like bell housing alignment clamps for a model JRIA6404 turboencapulator assembly....

I've needed something like that when fitting a "pad" to a piece of pipe

It's a CJ clamp.

Grounding clamps for smallish-diameter pipe?

Lester Bowman · Nov 11, 2013

They look exactly like the clamps used on a lawn mower "reel" grinder.The peg on each clamp engage into a hole on the reel side plates.The clamps are slid along the cross bar positioning the reel for sharpening.What? you thought the reel is removed for sharpening? Not on the small "push" reel mowers...only the longer heavier commercial reels.

I've spent many hours sharpening reel mowers.Back and forth..back and forth.Hot dirty and spark laden work.

Hmm.On second look these look identical.On a reel grinder they would mirror each other...The question remains...

Geez, can we give a rest to the turboencabulator part jokes?

Or at least use some of the original names in the work (see data sheet), such as "antigravic marzelvanes attached to ambifacient wane shafts".

I tried to turn one of those shafts on my lathe, but I found that without a Mobius attachment it is just not practical.

You require an infinite improbability drive to turn those.

Zero.

Don't ask why the hell I am looking at Ebay tool listings at 4:30 am.... but saw these:

Pair of Lathe Tool Post Grinder Wheel Dressers | eBay

"Grinder wheel dressers"????

It looks like a set of clamps for a punch grinder. Clamp the punch in the v and it pivots on the pin,
Punch & Die Sharpener | Punch & Die Sharpener

this will take you to the website for a Unipunch grinder.

That was my first thought then I looked closer and figured out they were for a Uni-punch sharpener. Crude as hell, but they work for that.

to me, they look like pipe hanging clamps- there are tons of clamps like that electricians and plumbers use all the time to hang things from overhead pipes- sprinkler pipes, drain pipes, stuff like that. I see this kind of clamp all the time up above the ceiling in commercial buildings.

They look like they could have been part of a fixture to align pipe and tubing for welding. If so, the smaller pins probably connected to some kind of adjuster to tweak the alignment.

Whatever they once were they could now be used for that.

The LH pin with the groove, mounts to the swivel. The roll pin is the locator. They might not be Uni-Punch, Whistler and Strippit had very similar grinders. Those were the first gen of punch grinders. All of them looked like a one ended, Baldor tool grinder. I don't remember who was the first to go with the vertical grinder. We got a Mate, which had a 3 jaw on one side and a mag chuck on the other.

Dunno if it's what they are intended for, but I've seen at least one photo of those used for, yes, tool post grinder wheel dressing. The V clamps onto a shaft held between centers (or in the chuck) and the diamond dresser is held as shown in that eBay photo. The carriage is traversed, truing/dressing the TPG wheel surface parallel to the carriage travel

Makes sense. I got one in an auction in chicago many years ago, and another at an auction in South Carolina a few years after that. Both were in boxes of miscellaneous "stuff"...

Anybody know what these are?
