Stop and Dwell Motion

Challenge:

Utilize stop, dwell, or reverse motion with a constant input velocity.

Solution:

Combine continuously rotating non-circular gears with round gears and differentials. Varying the ratio of the round gears enables the gear velocity curve to be translated along the velocity axis. The non-circular gears could provide a two-speed function, momentary stop, stop and dwell, or reversed motion, depending on the round gears being used.
