Historical Waterwheel Engineering Diagram - Mechanical Design & Function #3580717 (License: Personal Use)

This black-and-white engineering diagram depicts a horizontal-axis overshot waterwheel with evenly spaced buckets along its perimeter, supported by six radial spokes converging at a central hub. Adjacent to the wheel is a vertical gear assembly linked via a rack-and-pinion or spur gear, suggesting rotational motion transfer to a mill or pump. The sluice gate and flume indicate controlled water flow for optimal torque generation.
