elliptical path
I hope you realize you're proving the point that Mike and I showed in diagrams.
If the top crossbar is only oscillating back and forth, how does the top of the rod exit the perimeter of the frame? If it wasn't for the little wheels/arms rotating on the end of the oscillating bar, the top of the rod would be fixed to a simple back and forth oscillation and would remain inside the perimeter of the frame.
By the way, the claimed "linear" motion is actually a slight arc and not linear because the oscillating bar is on a piviot in the middle meaning the end of the oscillating bar is tracing an arc.
At the end of the oscillating bar are little wheels or arm that rotates around and causes the top of the lever to exit the permieter of the frame as the full path that is traced is elliptical.
