ABSTRACT:
An adjustable clutch mechanism is disclosed which may be removably mounted to a shaft to selectively vary the torque required to turn the shaft. The clutch mechanism includes a threaded, flanged bushing which receives a pair of friction washers and a clutch plate located therebetween. A nut, threaded onto the bushing, provides an adjustable force through a spring washer to control the force of the friction washers against the clutch plate. The bushing is removably mounted to a shaft so that it rotates with the shaft while the clutch plate is held stationary. The torque required to rotate the shaft is controlled by adjusting the nut on the threaded end of the bushing.
