Abstract
Centrifugal blade brake clutch apparatuses and methods are provided. In one aspect, a centrifugal blade brake clutch includes a rotatable clutch housing having an axis extending therethrough. The clutch housing can have a base and side walls. The clutch housing also can have a brake surface thereon and an integral clutch surface disposed on a side wall surface of the side walls. At least one centrifugally extendable clutch shoe device can be disposed within the clutch housing and configured for engaging the integral clutch surface of the clutch housing. A brake assembly can be positioned proximal to the clutch housing with the axis of the clutch housing passing therethrough. The brake assembly can include a brake member that has a braking surface and is configured to move in a direction parallel with the axis of the clutch housing to axially engage the brake surface of the clutch housing with the braking surface of the brake member.
