These have been operating the locks, virtually unchanged (since they work so well), since 1832. The rack and pinion mechanisms that operate the gate valves are an example.

These simple devices translate rotary motion (the turning of the wheel) into linear motion (by engaging the vertical teeth). These open or close flap valves located in the bottom of the gates. This drains water from the lock.

In the top photo, taken at Jones Falls, the early morning mist rising from the lake behind the lower lock gate made for a nice backdrop.
