Abstract
Link plates are connected into a chain by means of forward and backward connecting pins in each chained link plate. Frictional blocks having slanting outer surfaces are mounted around the link plates and affixed thereto by the connecting pins projecting from the link plates into the frictional blocks. The blocks may have holding pins inserted above and below the connecting pins, whereby opposite parts of the frictional block are attached to one another, enclosing the projecting ends of the connecting pins. The opposite parts of the frictional blocks attached by the holding pins have slanting V-shaped outward-facing frictional transmittance faces, transverse to the chain run for riding in the circumferential V-groove of a pulley. The blocks also have slanting faces longitudinally along the chain run on the side of the chain to be oriented toward a pulley, and straight abutting faces on the side of the chain to be oriented away from the pulley. The frictional block pieces engage the connecting pin ends and have through holes for insertion of the holding pins.
