摘要：
A range shiftable motion transmitting connection between a single element type carrier and a drive lever positionable by differential mechanism to any of n discrete positions permits positioning of the type carrier to 2(n-1) discrete type carrier positions through utilization of a translating lever responsive to movement of said drive lever through first and second ranges of positioning movement according to the relative positions of said levers. The levers are shifted relative to one another whenever the drive lever, after having moved to one extreme position, is moved to its other extreme position.
