Abstract
A conveyor travels in a helical path and is driven by a plurality of drive sprockets which are mounted on a common drive shaft. Each drive sprocket includes a yieldable portion which moves relative to a ring gear of the sprocket when the conveyor encounters an unyielding resistance. A sensor is activated in response to relative movement of the yieldable portion of the sprocket to provide an indication of which drive sprocket has sensed the resistance to conveyor travel.
