Abstract
The present invention relates to a clutch and a pulley assembly which provides a unique arrangement for mounting a clutch mechanism, a fixed pulley, and a variable speed pulley about a common mounting hub. More specifically, the invention includes an axially extending mounting hub adapted to be coupled to a rotatable drive shaft. A fixed speed pulley is rotatably mounted on the hub and is adapted to be coupled to a first belt for driving a first external device. A variable speed pulley is rotatably mounted on the hub and it is adapted to be coupled to a second belt for driving a second external device. The fixed and variable speed pulleys are coupled together to prevent rotation of the pulleys relative to one another. A clutch mechanism is mounted on the hub for selectively locking the hub to the fixed and variable speed pulleys. The clutch is shiftable between a released position wherein the pulleys can rotate relative to the hub and an engaged position wherein the clutch resists relative rotational movement between the hub and the pulleys.
