ABSTRACT:
A drive system for use with an endless drive member, e.g., a belt. The drive system may utilize an idler pulley that, in a first position, tensions the belt sufficiently to ensure power transmission between a driving pulley and a driven pulley. The idler pulley may be also be moved to a second position. In the second position, the idler pulley may both: relax tension in the belt to terminate power transmission to the driven pulley; and contact a brake member to quickly stop idler pulley rotation. Belt tension may then stop rotation of downstream driven pulleys. As a result, disengagement of the drive system and active braking of the idler pulley (and thus the driven pulleys) may both be accomplished via a single motion of the idler pulley.
