Google "antique yarn flower making tool"
I copied and pasted this from a person selling one.
This is a very clever brass device to make sweet little yarn flowers for a variety of knitting projects. The small dial on top turns to reel the tiny spokes in and out. When in the out position, you wind and tie off yarn to make a “flower;” then remove the “flower” by turning the dial to reel the spokes in. The flowers can be crocheted together to make blankets, scarves, sweaters, hats and more.
This winder will come in a small vintage card box and includes the original Hero brand Crazy-Daisy Winder instruction pamphlet, a needle, and an additional afghan pattern cut from an old magazine.
Shows wear and some tarnish, but works perfectly.
Measures almost 2” in diameter (not including extended spokes).
