Abstract: A link-type V-belt of relatively inflexible material including a first link having bifurcate ends and a second link having single ends which are pinned together by multiple pins in alternating fashion. Two pins are employed at each intersection between links and are semicylindrical for rolling contact between pins and for pivotal movement with the associated link. Broad transmission faces are associated with each link in inclined arrangement for conforming to a V-grooved pulley. Lubricant relief passages aid in the power transmission of the pulley by allowing lubricants to flow from the transmission faces of the belt. At the same time, the belt may be lubricated to further reduce internal frictions and sliding friction on associated pulleys. Informing the link having bifurcate ends, two link members may be positioned together with a spacer therebetween. Pins are calked in place to retain both the pin in position and the link members together.

The chain-belt is constructed of a plurality of ranks or sets of interleaved links, each rank being joined to the next adjacent rank by pivot means, such as round pins, or a pin and rocker, to permit articulation of the belt. Generally trapezoidal load blocks are located between the pivot means of each rank or set of links, which blocks have opposite edge surfaces to contact the flanges of the pulleys. At least one load block has a differently dimensioned or arranged contact area than the other load blocks. This changes the generated noise pattern produced when the chain-belt engages the pulley flanges.

Abstract: A power transmission chain-belt, especially adapted to transmit power between the pulleys of a pulley transmission, such as a variable ratio pulley transmission. The chain-belt is constructed of a plurality of ranks or sets of interleaved links, each rank being joined to the next adjacent rank by pivot means, such as round pins, or a pin and rocker, to permit articulation of the belt. Trapezoidal load blocks carried by the chain have angled edge surfaces to drivingly contact the flanges of the pulleys. In one embodiment of the invention, a block is located between each adjacent pair of pivot means and at least one block has a different width than the other load blocks, so that its edges are free of contact with the flanges of the pulleys and thus do not drivingly engage the flanges.Substantially the same effect is achieved by "skipping" one or more load blocks in the assembly, i.e. by eliminating one or more load blocks in the chain-belt.

The link apertures are generally round and have a surface substantially engaged by a back surface of a pivot member.
