Jiff,
Unfortunately, your mis-understanding of the concepts of force, inertia and momentum need a bit of review if you think you can divorce inertia from the (non) resultant liftingforce or the time rate of change of the system's momentum. Newton would explain (has expalained) that the concepts of a lifting force, the inertia and the momentum are all locked in, in spite of your confusion.
Your diagrams can, however, be used. The reverse side will record many cribbage scores......
PS he Dean drive simply converts rotary to linear motion, it produces no force nor any lift. It is a sophisticated (impractical?) reciprocating crank equivalent.
