What is this piece on front skewer?

I bought a bike, and on the front hub, there is this weird spacer thing. It is marked: PAT JAPAN <-------TO RETENTION SANSIN PAT JAPAN S
There is a tab that sticks off one side, with a hole in the end.
The other end has a bent over, angled tab.
This is "mounted" on the skewer, it spins freely, and for whatever reason, the skewer does not have any of the conical springs on it.
If it matters at all, it is on a '92 Bridgestone XO-1.
So, what is it? Can I remove it and put springs on the skewer instead?
Thanks

Is it a Sansin Hub?
Edit: it looks like that tab would lock into the bottom of the dropout. For what reason I can't imagine. Other than to keep it from spinning so that other hole can do its job. Whatever that may be.
Edit2: That other hole could function as a second eyelet. Is it threaded?

No, it is a Shimano RX100 HB-A550 hub, Shimano skewer.
That piece just seems so out of place, and it's kinda bugging me.

I agree that the little tab fits in the dropout opening. That is the only place it "fits" without causing closure issues.
There is also the letter "L" on it, and it's on the left side, so I am wondering if there there is supposed to be a right side too?
This is how it looks installed with the tab in the dropout slot.

Sansin thingy on a Shimano hub and Shimano skewer? Yeah, I would just get rid of it. I have two sets of RX100 hubs, and both have the typical conical springs on their skewers.

As for function -- maybe to hold something for a bike computer or mechanical speedo? None of the Sunshine/Sansin hubs on Velobase have anything like that piece.

I think it's for a speedo. This pic from an Amazon analog speedo listing has a similar piece that goes to the hub.

I'd surmise it's some sort of lawyer lip type device for wheel retention when loose

Thanks for all the info and advice. There was a Vetta computer on the bike, but that all mounted on the other side fork blade.
I think it's off to the parts stash to grab some springs!

If it's marked left, then there could have been a right side version..... which makes me think that it could work like a fender stay mounting eye, if your dropouts do not have them. It might work the same for the back wheel too.

After trying to remove the wheel, I do agree that it is some kind of lawyer lip variation, as I did need to significantly loosen the skewer and rotate that piece before the wheel came out of the dropouts.

If it's a lawyer lip thingamajig, what does it attach to on the fork to retain the wheel??
Schwinn had bosses on their fork ends to interface with layer lip clips but if the wheel came originally with the bike pictured, we do not see any means of retention on it.

I'm thinking the seller knew the buyer, found this among his lawnmower tools and thought "let's see how long this will keep 'em busy".

Don't know whether this patent applies; there's no drawing of the item.

Does it keep the axle positioned in a horizontal dropout in which there is not a positioning screw?

That is exactly what it is. There are a lot of similar patents. Springs work better, IMHO.

That brings back some memories. I had one of these on my Huffy Bay Pointe 3 speed, a birthday gift when I was about 8 years old.

Only needed on one side, since the wheel would need to tilt further than the fork legs would allow in order for the other end of the axle to move out of it's dropout.

Amazingly simple, but can't the thing be inadvertently defeated by being in the wrong rotational position as the QR lever is flipped?

I suppose if the adjusting nut were Loctited to the shaft that the operator wouldn't be able to flip the lever if the device were in the wrong orientation.
But if the nut is backed off then the QR could be flipped with the device in it's "release" position AND with the lever tension perhaps set too loose.

The problem with this device is that it would require the operator to know how to use it, which makes it somewhat redundant to the QR lever.
It would work as intended though if the only setup problem were incorrect tensioning of the QR nut (or if the operator used the QR handle as a wing-nut). That's the only benefit that it offers, sparing the operator from having to determine quantitatively just how tight that the QR lever tension should be set, and not having to turn the "wing nut" (qr lever) tighter than is comfortable on the hand (if used improperly).

The idea of adding complexity to the setup of something that the operator is already doing wrong is almost humorous. But hey, it might work, right?

That's exactly what I was thinking the "L" stood for.
