Driveshafts
The video discusses the evolution of driveshafts from horse-drawn implements to modern automobiles.
Watkins and Bryson's patent in 1861 introduced the first modern conceptualization of a drive shaft.
Early automobiles primarily used chain drives for their simplicity, reliability, and manufacturing efficiency.
Ball and trunion universal joints superseded Cardon joints, allowing for up to 25 degrees of movement.
The late 1920s saw the introduction of double Cardon shafts as a solution to the limitations of single Cardon universal joints.
