Abstract An article transferring apparatus including a canted overhead conveyor for transporting articles, a fence located adjacent to the lower edge of the overhead conveyor for keeping the articles from coming off of the conveyor, a gate forming part of the fence for permitting articles to come off of the conveyor, and gate operating apparatus for operating the gate. A lower conveyor for transporting article is located below the overhead conveyor and a chute extends from the gate in the fence associated with the overhead conveyor to the lower conveyor to permit articles to pass from the overhead conveyor to the lower conveyor when the gate is open. The chute itself has three regions which enable it to efficiently transfer articles without tending to damage the articles.
