  • Patent number: 4607745
    Abstract: A bucket conveyor wherein the buckets are pivotable about transverse horizontal axes and have first cam faces which slope upwardly and rearwardly counter to the direction of movement of the buckets. The cam faces of successive buckets can be engaged by a roller which can be moved downwardly to tilt the buckets. The buckets have straight second cam faces which come into contact with the underside of a stationary rail in response to partial tilting of the buckets to maintain the buckets in tilted positions during travel along a selected portion of their path. The downstream end of the rail forms a ramp to effect a gradual pivoting of successive buckets back to untilted positions.
