Abstract
An adjustable chain drive system is adapted for uses such as moving product through a conveyor system, and can be configured using a chain, belt or similar structure. Two driven sprockets are movable on a slide, allowing the distance between them to be adjusted. In one example, such adjustment allows conveyor belts to be separated by a desired distance. A drive sprocket and endless chain is used in the drive system. In one configuration, the endless chain includes an adjustable chain segment separating the first and second driven sprockets. To compensate for movement of the first and/or second driven sprockets and change in length of the adjustable chain segment between them, lengths of first and/or second secondary adjustable chain segments adjacent to the adjustable chain segment are varied.
