Abstract: A material handling apparatus for transporting parts having a bowl provided with an upright curved wall surrounding a rotatable floor. The curved wall is formed with a track that supports an endless belt capable of bending in an edgewise direction for movement along a helical path from an entrance point located at the level of the floor to an exit point located above the entrance point. As the belt moves along the track, it gradually inclines towards the center of the bowl with a portion of the belt being sufficiently inclined to cause parts to move into engagement with a rail located at the inboard edge of the track and formed so that parts not properly oriented will drop by gravity to the rotating floor.
