  • Patent number: 4832182
    Abstract: An endless loop tractor drive mechanism has equally spaced pushers meshing with a bucket train where its filled circular buckets are traveling along a substantially straight ascending path to a dumping support wheel. Wire rope cables or other flexible tension elements extend between the buckets. The pushers have drive rollers for pushing the buckets, and additional rollers for guiding the cables. Additional support wheels guide the bucket train along a catenary loading span where the buckets are dragged through bulk material to fill the buckets. At least two pushers engage at least two successive buckets at all times, to distribute and share the lifting load among two or more buckets. Due to the straight ascending path, the cables are not flexed when the lifting load is applied. Thus, the combination of high tensile stresses and high cable flexure is avoided. Wear and tear on the cables are thereby minimized. Fraying and breakage of the cables are no longer problems.

  • Patent number: 4766994
    Abstract: The present invention is directed to a conveyor belt system for transporting materials by directly driving a conveyor belt. This is accomplished by directly driving a plurality of clips attached at their inner end to the belt and securedly coupled at their outer end to a pair of continuous cylindrical cables. Even though the belt is directly driven, the subject conveyor system can effect continuous relative movement between the conveyor belt and cables, thereby compensating for differences in the respective lengths of said belt and cables and in the configuration of the respective drives. This is accomplished in great part by the novel construction of clips of this invention which is designed for facilitating secured engagement with the cables and effective and efficient movement of the conveyor belt. This results in the continuous, uninterrupted transportation of the materials carried by the conveyor belt for extended periods of time.

  • Patent number: 4506781
    Abstract: An endless belt with bottomless buckets or other gripping elements bolted to its outer surface at spaced locations, has endless wire ropes each loosely received in a longitudinal bore formed in confronting faces of two rows of discrete blocks of resilient material bolted to the inner surface of the belt to form a continuous rail member. The wire ropes are firmly coupled to the endless belt as they pass around end pulleys together by the wedging action created as the tension in the endless belt pulls the associated two rows of discrete blocks which have tapered side walls down into peripheral grooves in the end pulleys which also have tapered, but slightly narrower side walls. With the belt firmly coupled to the wire ropes, radial digging forces tending to pull the belt away from the end pulleys, and lateral forces generated as the digger is advanced into a pile of bulk material on a bias which tends to cause the belt to creep laterally on the pulleys, are resisted by tension developed in the wire ropes.
