ABSTRACT:
A motion transmitting device of the quadrant drive type has a wheel, preferably toothed, a plurality of independently movable elements for successively engaging the wheel, a datum member and an eccentric effecting eccentric relative motion between the wheel and the datum member. Connector pins movable in ovoid or circular holes in the wheel and datum guide the movable elements into and out of engagement with the wheel. The movable elements are not linked, as in a chain, but means are provided to prevent them from any tilting or substantial rotation with respect to the datum member.
