Abstract: There is disclosed a conveyor comprising an endless sprocket-toothed traction chain disposed about and engaged by at least two sets of sprocketed teeth reversing means where the chain carries a carrier which, at its trailing end, is attached to a roller-carrying axle which is connected to the traction chain through a coupling flight which is detachably secured to the traction chain. The carrier is connected at its leading edge to a chain-connecting axle which, in turn, is connected to a supporting link. The supporting link is secured, in turn, by a pin to a chain link of the tractor chain. The pin is disposed above the center line of the traction chain at the center of the length thereof. The tooth spacing of the traction chain sprockets are such that a tooth space is associated with the pin of the supporting link as the pin enters the sprocket.
