understood that the chain belt 29 is a continuous loop chain belt 29 comprises the combination of a carrier 31 and a plurality of load blocks 33 of either one piece construction or a laminate assembly of a number of thinner load block plates an assembly of plates 33 is advantageous as the thin plates can be easily die stamped from sheet stock material thereby avoiding costly machining carrier 31 in fig3 has a longitudinal axis 30 and comprises a plurality of interlaced links 37 including edge links 38 illustrated in a 5 4 5 alternating set arrangement although the particluar carrier configuration is not relevant to the invention each link 37 38 defines a pair of apertures 36 to receive a pivot means 41 through the transversely aligned apertures 36 of adjacent links to join the alternating sets of links 37 and edge links 38 which permits articulation of the carrier 31 to engage pulleys 10 and 14 of the pulley transmission the pivot means 41 can be a round pin or a pin and rocker both known in the art as illustrated in fig3 a load block 33 which may be either a solid member or a plurality of thin plates encircles each set of links 37 between adjacent pivot means 41 each load block 33 as shown in fig4 has a generally trapezoidal shape and defines a window 43 with a top surface 45 a bottom surface 47 and mirrored side surfaces 49 load blocks 33 define outer edge surfaces 51 which surfaces 51 frictionally engage the flanges of the pulleys 10 and 14 of a transmission fig3 is representative of a.
