Fusee

Description

The Fusee was invented to compensate for the reducing turning power (or Torque) of a clockwork spring as it winds down.

Features and Applications

The Fusee is essentially a conical pulley and the drive is transferred progressively from a large diameter Driver to a smaller diameter Driver with a consequent increase in Mechanical Advantage.

Cone shaped pulleys are sometimes also used in Potters' Wheels to create a variable speed drive.
