These are on our 1915 Touring car. People in this neck of the woods call them PG&E wheels probably because Pacific Gas & Electric Co. used them on their field vehicles way back when.
Here's what the lugs look like for these wheels.
Typical that when new materials are introduced you make the item look as the old design, just another material.
The following patent only covers the method of
attaching the outer end of the spokes to the rim,
and may or may not be correct for the method
used on the Atlas wheels. It is however very similar
in appearance to the wheels in Jay’s photos.

Do you think they originally came with "Atlas" hub caps?
Les, I believe they did but I haven't come across any.
Now THATS a marketable product...
Except ... Dykes gave examples of steel wheels that would bend and not return to original shape. Chevy and some others had disc wheels in the mid-late twenties, but they were not that popular compared to artillery wheels, or later, wire wheels.
