Abstract: An improved bucket conveyor chain that uses a series of metal plate type links 3 connected together at adjacent ends by a pair of bars 5. The bars 5 also hold adjacent plates up off the wheel's 1 driving surface, they also provide a surface for attaching buckets 17 and guide bars 19.

Abstract: A continuous bulk unloader/reclaimer that utilizes a bucket conveyor digging chain 18 to remove material 16 from the holds 14 of vessels such as ships, barges, railroad cars, pits, stockpiles etc. The conveyor chain 18 is comprised of an elastomer bushing 32 that allows for the bucket conveyor chain 18 to circulate at high speeds with increased durability. Many improvements are described to make the unloader/reclaimer practical.

Abstract: A chain 32 and sprocket 10 combination which reduces chordal action and wear allowing for higher output and greater durability of the devices that use chains and sprockets. The chain 32 has hinged joints equipped with a torsional spring 42 that resist hinging and thus reduces chordal action. The sprocket 10 has cam manipulated teeth 12 that prevent both sprocket tooth and chain wear.

Abstract: This invention relates to a method for transmitting power to and from wheels via a train of links. The wheels have cam actuated members that effectively control the radial position of individual links as they enter, travel around, and exit the wheels; thus, allowing for high operating speeds. The wheels also have cam manipulated members that transmit power to and from the train of links such that the required engagement and disengagement of the wheel and train of links occurs without relative slip greatly reducing wear and allowing for high operating speeds. An arrangement of links is disclosed that is especially suitable and complimentary to the wheels. Other devices are introduced that aid the wheels and train of links as they work.
