ABSTRACT:
A governor for controlling the speed of a drive shaft comprising a flywheel mounted to a revolving drive shaft by a pair of diametrically opposed pins extending through the flywheel, along a diametrical line of the flywheel, and being respectively received by two oppositely disposed spiral slots along the cylindrical wall of the drive shaft. The flywheel and pins are slidably mounted to the drive shaft such that an increase or decrease in the speed of revolution of the drive shaft will cause the pins to move along the shaft in the slots and the flywheel to traverse along the axis of rotation of the drive shaft. Mechanical linkage is connected to the flywheel so that the movement of the flywheel will engage or disengage a friction clutch drive assembly operatively associated to the drive shaft, or alternatively, will control the rate of flow of fuel to an engine operatively connected to the drive shaft. In a conventional internal combustion engine, a slight change in the speed of rotation of the drive shaft causes the flywheel to travel along the shaft and, in turn, through its linkage to the carburetor, change the amount of fuel flow to the carburetor. In a farm combine, the governor is attached to the beater drive shaft and disengages the conveyor mechanism upon a decrease in the speed of rotation of the beater drive shaft.
