Abstract: A shelving unit includes one or more elongated back panels and a pair of elongated side panels all of which have longitudinal edges in the form of a rollback that provides flanges for interlocking with edges of other pieces. An elongated panel connector in the form of a channel having a pair of legs that extend angularly inwardly is utilized to connect the rollback edges of the back panels to form the back portion of the shelving unit.

Abstract: Apparatus for depositing cattle feed in an elongated bin in an evenly distributed relation including a conveyor belt having a surface for supporting feed, a hopper for depositing feed on the supporting surface of the belt, and a plow including a plow face positioned adjacent the supporting surface of the conveyor belt and adapted to sweep feed off of the conveyor belt into the feed bin. A restraining member is carried by the plow and engages an edge of the conveyor belt for supporting the belt in position and preventing it from moving laterally.

Abstract: Apparatus for depositing cattle feed in an elongated bin in an evenly distributed relation. The apparatus includes a conveyor belt positioned above the feed bin and for supporting feed, a hopper for depositing feed on the supporting surface of the conveyor belt, and a plow adapted to move along the length of the conveyor belt to sweep feed off of the conveyor belt into the bin. The plow is driven by a flexible metal cable reeved over pulleys positioned at opposite ends of the conveyor belt.
