Quilt in an unusual design by Wilhelmina Schultz (1857-1942), Newhall, Iowa. The family who brought this quilt in for documentation at the Iowa project thought it dated from 1860-1890.
You could describe it as kind of a geometric wreath or a cog wheel. This one has 14 scallops around the wreath.
Newhall in 1912
She was born in Germany and settled in the very German community of Newhall, west of Cedar Rapids, where she is buried with husband Henry.

And her family here:
In primary colors with simple shapes Wilhelmina's wheel has a lot of modern appeal. It does seem to be one of a kind although it has cousins.
This one quite close kin.

Perhaps evolved from this kind of wreath.
Related perhaps to the more common feather wreath seen in
Maryland area albums, like this one pictured in Marguerite Ickes's book.
Update: Well, I thought that was all the pictures I had of sprocket wheels, but then I found this stash:
