Abstract
A vacuum cleaner overload clutch having an overload cog, a spring mount, and an overload spring. The spring is engaged with the cog to provide torque transfer, and disengaged from the cog to terminate torque transfer. The spring may not reengage until the parts stop rotating. A weight may be provided to bias the spring into the disengaged position, and the spring may have an engagement portion that is captured between the overload cog and a wall on the spring holder when the clutch is engaged. The clutch may be part of a system including a motor and agitator, and may have other features, such as a graduated engagement clutch.
