ABSTRACT:
A toothed transmission chain or belt is described for use in coupling spaced sprockets or gears. The chain is formed of molded polyurethane or other plastic having sprocket engaging teeth molded onto a supporting unitary molded backing. The molded portion is reinforced by one or more metal cables which are embedded in the molded plastic portion. An improved engagement with the sprockets is provided for by providing lateral slots in the chain teeth thereby giving them variable width. Additionally, the chain may be furnished or originally formed in indeterminate lengths and then fashioned into an endless chain by exposing and splicing together the ends of the steel reinforcing cables.
