ABSTRACT:
A conveyor comprising an endless accumulation chain and at least two sets of devices for effecting incremental movements of the chain at respective stations. Each set of devices includes a first device for engaging and disengaging respectively the chain, a second device engaged to the first device for moving it from a first position to a second position while it is engaged to the chain for effecting an incremental movement of a portion of the chain and for retracting the first device to the first position while the first device is disengaged from the chain, and a third device for engaging the chain to lock the chain portion in a fixed position while the first device is disengaged from the chain and for disengaging from the chain when the first device is engaged to the chain portion so that the first device may be moved to the second position for incrementally moving the chain portion. In order to incrementally move the conveyor chain, the first device is engaged to the chain, the second device is disengaged from the chain, the engaged first device is moved from the first position to the second position to effect incremental movement of the chain, the second device is engaged to the chain to maintain a chain portion position, the first device is disengaged from the chain, and the first device is retracted to the first position to repeat the method for another incremental chain movement.
