Anti Rotation Washers

[SirMike1983]

Thanks for your replies everyone, I really appreciate it.
I was surprised to find that my front hub does not use any jam nuts to lock the cones in place, and it doesn't use a washer against the cone on the non-drive side. If I install the no turn washer on the drive side the rim ends up centered in the forks and the spacing seems right for the fork, so I'll leave it with that setup.
The photo below shows what I'm ending up with for hardware. It's just a repeat of what you all have said above, but I'm including the photo in case anyone searching this subject again in the future will find it helpful.
From the left; Non-Drive side rear, Drive side rear, Non-Drive side front, Drive side front.
Again, this is on a 1954 Schwinn Traveler.
Thanks again everyone!

Looks like you've got what you need.

Eric, if we make the assumption that your fork is perfectly in alignment. and that your front wheel hub has been perfectly trued to be centered within the width of the rim, your front wheel should be "off center" by the thickness of that non-turn washer.

If it looks centered with only the non-turn washer and no flat washer on the non-drive side, either your fork alignment is off, or the front rim is not correctly centered to the front hub.

It's really easy to measure if the hub center is off. You do not need any special tools, just a metric ruler, or caliper. Drop the front wheel into the fork and measure from the rim to the fork leg (do only one side). Then take the wheel out of the fork and reverse it 180 degrees. Remeasure the rim to fork distance on the same side as your first measurement test. It should be "exactly" the same on both tests.

If the measurement "is the same", your fork is off on alignment. If the measurement "is different", then your wheel is slightly out of true (hub center to rim).

The bikes are pretty sensitive to small adjustments in the front hub spacing. This is why adding a Huret Speedometer driver is not "just a bolt-on" most of the time. Many times, it requires the hub center checked and adjusted (re-trued). They included shim washers for the drivers in the original parts kits. This solved the spacing problem but made the alignment problems even worse.

On bikes with front fender braces, they had an additional pair of smaller flat 5/16" that were placed against the fender braces before the nuts went on. These washers looked almost like a "AN" washer in the outer size". So, if the bicycle has front fender braces, it's missing three more flat washers.

John, yes, the wheel dish is off a bit. I could see it when I had the wheel in the truing stand, so I checked it with my dishing gauge.
I did adjust the dish a little bit, but started getting confused about which way I was going when the results didn't match what I expected to see.
I assembled the wheel into the fork with the no turn washer on the non drive side and the wheel was clearly off from centered in the fork. When I put the washer on the other side the wheel looked to be perfectly centered in the fork so decided to just call it good before I did more harm than good.
On a wheel with new spokes & nipples I would play with it more, but these ancient old spokes & nipples are kind of an "iffy" situation.
I was surprised that I was able to get them to adjust at all(I had applied Kroil to the nipples the day before). Since the wheel now sits centered in the fork, I just didn't want to press my luck.
