<p>IMPROVED METAL CHAIN-BELT An endless power transmission chain-belt (31,61) constructed of fined sets of links (33,34) and blocks (43,44,63,67) surrounding sets of links, the links (34) in some sets having a pitch (b) larger than links (33) in other sets. Some blocks (43,63) are of such width to engage pulley flanges of a pulley transmission while other blocks (44,67) are of a lesser width to "skip" the flange engagement. The latter blocks can be omitted, if desired.</p> |
