Ok, what am I missing here?

[cyclingday]

This one has me stumped.
I’m working on a 1898/99 Schwinn/World, model 22 Roadster, and the method for securing the handlebar and stem to the fork, is a new one to me. I can see that the handlebar threads into the stem, and then is clamped into position with a large hollow bolt.
At first, I thought the hollow, was just a way to lighten the large diameter bolt, but now, I’m beginning to think that there is supposed to be a long quill bolt that passes through the hollow to cinch up the plunger type expander wedge that is described in the 1899 catalog.

The catalog describes the expander wedge of both the seatpost and the stem, and shows a diagram of both, that look similar.
So, I pulled the expander wedge and bolt from the seatpost for comparison.
It seems that this may be what I’m missing, but without ever seeing anything like this before, I thought I’d throw it out there, to see if anybody had any experience with a stem like this before?
Am I correct, in assuming, that the stem quill bolt broke off at the expander wedge, and is supposed to pass through the hollow, handlebar cinching bolt?
It would be a smaller diameter than the seatpost bolt, which might explain why it broke off, if that is in fact what happened?
If anyone has ever seen this type of piggy back type fastening system before, please let me know.
As for now, I have no idea what, or how, the stem is held in place, on the 1898/99 Schwinn/ World, model 22 Roadster.

Any help on this, would be greatly appreciated.
Thanks!

Long quill bolt often with small square bolt head.
A little later a hex bolt head.

Alright!
You guys are great!
This just in from another one of our esteemed members.

So, glad to know, what I’m supposed to be seeing, before I start beating on it with a hammer. Lol!
Thanks, guys!
Much appreciated!
Anybody got a spare Hussey stem/bolt?
If so, I’m interested.

Best to use a brass drift against the part to avoid impact damage. You then hit the brass drift with a BFH to transfer the blow. Happy to loan you the brass drift if you need it.

Your goosenck looks longer. I doubt the bolt on this gooseneck would work.

My question is about the "reversed angled wedge"? It looks to me like the stem bolt would have "to push out" the wedge, and not "pull the wedge up into the handlebar stem" to expand?

If this is correct? The stem bolt would need some kind of a shoulder (or Circlip) to push against the handlebar binder bolt.

I've not seen a stem like this before, very interesting.

You have to appreciate the quality of the machine work on these parts. This part was not made by some automated CNC machine. It would be my guess that the purpose of the threading of the stem to handlebar center was to increase the clamping surface area. A threaded part (increased surface area) would require less clamping torque to stay tight.

Success!
I just got the stem out of the fork, with no issues.
The part that was down in the fork, still looks as fresh as the day it was made back in 1898.

My guess is, that it’s been a very long time, since that part has seen the light of day.
