ABSTRACT:
A multi-ratio drive utilizing a chain link or a belt segment specifically designed to engage a sprocket having a plurality of cylindrical pins radially spaced from one another in a circular array. The chain links or belt segments are connected to one another to form a flexible tensile member. The chain embodiment is formed of a plurality of link plates each having a first and second end pivotably attached to one another and extending along a chain axis. Each link is provided with two teeth projecting transversally from the chain axis and each having a concave drive face having a radii substantially equal to that of the sprocket pins to be engaged thereby.
