Abstract
A drive system for use in a piece of an appliance includes a drive shaft and a first rotary coupling and a second rotary coupling. When the drive shaft is rotated in a first direction, the first rotary coupling and the second rotary coupling rotate about an axis of the drive shaft at a same speed. When the drive shaft is rotated in a second opposite direction, the first rotary coupling and the second rotary coupling rotate about the axis of said drive shaft at different speeds.
