Abstract
A continuous push-drive chain formed by a plurality of blocks, each of the blocks having a letter V-shaped configuration in side elevation, defining large engagement surfaces relative to overall block size; and, structure for connecting adjacent blocks to one another disposed at one distal end of the V-shaped configuration, whereby large pushing forces between the blocks may be transmitted substantially unidirectionally and independently of the connecting structure, simultaneously increasing chain load capacity and reducing chain wear.
