ABSTRACT:
A self cleaning pulley for conveyor belts in which a layer of elastomeric material such as polyurethane is applied to a cylindrical steel member, the layer having a plurality of generally longitudinally positioned resilient ribs extending radially outwardly from the body and spaced uniformly around the periphery thereof. The spaced ribs define generally longitudinally spaced grooves for receiving foreign material carried between the pulley and the belt. The surface of the body between the ribs slopes from a point near the longitudinal center of the pulley inwardly toward the opposite ends to assist in the flow of material dislodged from the belt and pulley to travel to the ends of the pulley where it is discharged. The ribs are resilient but firm and are of such a shape that they will produce a scraping and vibrating action on the belt to dislodge any foreign material between the pulley and belt, causing it to be moved along the grooves of the pulley and to be discharged therefrom.
