(under subclass 701) Apparatus having a plurality of bucket means and a means, either incorporated with or separate from the bucket means, moving with the bucket means and providing a covering for the space between the bucket means, as they are spaced for movement, so that material or load will not tend to be lost from the conveyor should it be released to the conveyor in the area between the buckets.
SEE OR SEARCH THIS CLASS, SUBCLASS:
526+, for a conveyor system having a gravity conveyor section and including a moving (e.g., traveling) flow control means which is coordinated with a power-driven section (often of the bucket type) and which means may be in the nature of a "gap closer".
