Abstract
A self-centering variable diameter drive pulley, driven from an engine, receives a first drive belt which is also received on a self-centering variable diameter driven pulley. One or more engine accessories are driven through the variable diameter driven pulley at a relatively constant speed through a wide range of engine speeds by virtue of the variable diameter pulleys, one of which changes diameter in accordance with the speed at which it rotates. Another accessory, or accessories, are driven by pulleys which receive a second drive belt. The second drive belt is received over the first drive belt at the variable diameter drive pulley to transmit power from the drive pulley to said other accessories.
