19th century Russian thread winder.

Swifts had to open and shut in the same way as an umbrella. The axis spoke or central rod facilitates this movement. The strips are joined with steel rings, and a thumbscrew set on the lower shaft keeps the swift in the desired position. A skein of silk thread or tapestry yarn was wrapped tautly around its extended frame, which would then rotate as the thread was wound around a sewing spool.
