Abstract
Abstract In the illustrative embodiments of the invention described herein, a drive chain comprises at least two chains arranged in superposed interlocking relationship. Each chain comprises a succession of links with the overlapping portions of adjacent links connected together by pin members. The links of each chain further include bearing surfaces and when the two chains are arranged in interlocking relationship, the overlapping portions of the links in one chain engage the bearing surfaces of the links composing the other chain. To drive or guide the drive chain, a sprocket having a pitch equal to one-half the distance between the overlapping portions of adjacent links is provided.
