How might a repeat lever act as a continuous cycle?

       I am speaking specifically of Repeat Lever Type 2, a form in which
      a heavy counterweight acts by leverage on a short end, while the
      longer end supports a rolling weight on a triangular track, that moves
      upward along two slopes, and downward at the point of greatest
      leverage, allowing the rolling weight to free-fall.

      Experiments with this type may be found at Repeat Lever Experiments.

      It is my observation that although upward force of the lever on the mobile
      weight may not act directly in accordance with its natural movement, in
      the desired implementation the majority of the weight is supported by the
      track, resulting in a situation where, so long as the weight rolls, less force
      must be needed than to lift the weight entirely.~1

      Thus the primary difficulty, if geometry is perfect, is simply to create a
      closed loop in which the counterweight acts by leverage at the point of
      greatest leverage, and is allowed to rise through the natural pressure of
      the counterweighted lever along two portions of ramp through the rest
      of the cycle.

      This implementation is manifest within diagrams at:

      Diagram 2: Repeat Lever 2, Variation
       Diagram 3: Repeat Lever 2, Variation 2

      Primary Criticism of this Design:

      There has been very little criticism upcoming except from relatives, one
      of them being addressed in the nature of weight on slope (including the
      footnote below). In fact this design is relatively flexible.

      Footnotes:

       1. It is certain that considerably greater counterweight force is needed to
      resist an unsupported weight than a weight inclined on a track.
      This is like the difference between lifting a car fully from the ground, and
      rolling it up a slight incline. There is a difference, as much as some men
      would like to deny it (even lifting two wheels off the ground is only half the
      weight of the car at most). Thus the leverage force of the unsupported
      mobile weight is much more effective on the lever than the supported
      mobile weight during the rising portions.
