input lever details
The input lever's rotation around it's own axis has no bearing (pun intended) on the rotation of the translation coupler. Plus, it has has a pivot, which would prevent it from spinning on it's own axis to begin with. In some of the video after the 2nd, half, it looks like the input lever rod is rotating, but I believe that is an artifact of the old film. If you look at the space under the pivot in the scenes to the right of center, you see that is appears to be clearly not rotating. So instead of it spinning...it is being held by a bearing in the upper mechanism and on the translation plate so they can rotate around the fixed position of the input lever.
It is the input lever's position in space, which determines where it's other end down by the pivot is located and that location will determine where it's relationship with the translation coupler will be. You can move the input lever into any location and keep it there and the translation coupler will move freely around the bottom of the input lever and the same with the upper input mechanism that moves the top of the input lever.
I don't think I pointed out why I believe the lever is spring loaded where it has it's pivot - if you watch the video, not only is the input lever rocking back and forth, you can see the metal retainer plates with bolts at 90 degrees perpendicular to the pivot go back and forth with the lever - BUT, you see that it is not locked to the same motion, it lags behind a bit with some dampening action - that is very easy to see in the original video. Go to 0:35 to 0:39 of the video and you will see it: Gravity Power | A & P Electronic Media – Digital Publishing by Aaron Murakami & Peter Lindemann
