A clue: These were used in antique spring-powered mechanical watches and clocks, a Fusee is a cone-shaped pulley with a spiral groove around it, wound with a cord or chain which is attached to the mainspring barrel.

Is that it? Fusee

Dwarf · 27 Jan 2011

Correct, Derek. :)

The drawing was a pictorial representation of a fusee. Used in antique spring-powered mechanical watches and clocks, a fusee is a cone-shaped pulley with a spiral groove around it, wound with a cord or chain which is attached to the mainspring barrel. Fusees were used from the 15th century to the early 20th century to improve timekeeping by equalizing the uneven pull of the mainspring as it ran down.
