Abstract
A dehider includes a pneumatic motor driving a pair of disk blades in opposed cutting oscillations and a governor that controls the speed of the motor. Governor balls, acting as centrifugal weights, spin with the motor and push against an inclined flange on a valve head to move the valve head towards a valve seat. The motion of the valve head compresses a biasing spring and restricts the flow of pressurized air as the desired speed is exceeded. As speed decreases, centrifugal force decreases and the biasing spring opens the valve to provide additional power to the motor. The disk blades are provided with a cylindrical central lip that substantially increases the area of the central bearing that the blades turn on and produces significantly longer blade life.
