" S " Sidewalk Bike Rack

[Vicious Cycle]

I cannot find any information about this sidewalk stand I found, Sure looks like a Schwinn "S" to me ?
Heavy riveted wrought Iron construction. set up for a Balloon wheel. I am guessing 30's/'40's ?

That must weigh a ton. Are those rings for locking up your bike? Pretty cool bike stand.

Yes the rings are to lock up the bike. It is Very heavy, I can see no evidence that it was ever bolted down, likely because it would take a crew of tweekers to carry it away with a bike or three attached.
