NATHAN COPPEDGE--Perpetual Motion Concepts





"Coquette" Device
SUMMARY
A device resembling the outline of the body of a bird, consisting
of one piece of halved metal tubing running through the center
over a pivot, with two further halved tubing pieces running
downward roughly in an arc on either side, and joining the
center tube at either end.
One end is shorter, that is, closer to the pivot and more heavily
weighted (this is essential), so that when a large metal ball
weight is placed on the short end, it follows a slight downward
slope past the pivot, where its weight begins to bear down on
an upward grade. At this point it has leverage sufficient to lift
the short end somewhat, so that as it moves onward it applies
further and further leverage.
When it reaches the end of the long end of the structure of
tubes, the channel bisects backwards on a lower grade, giving
two possible (and identical) paths. Each is graded in such a way
that it is sloped in the horizontal in relation to the pivot joint. The
predicted result is that, since the long end has reached its lowest
point, the ball weight rolls until it reaches a point of lesser
leverage, where the heavier weight of the short end of the
structure begins to provide additional slope until the weight
returns to the same point on the short end of the structure.
The principle, much like the Repeating Lever type 2, is that
return might be made on leverage through the use of
counterbalance weights.

STATISTICS: Coquette
VOLITION: 2 (2 active u / 1 dual-axial u)
EQUILIBRIUM: 0.5 or 1 (1 u / 1,2 stems / 1 cycle)
EFFICIENCY: 2 or 4 (2 Ve / 0.5,1 VE)
VOLITIONAL STATEMENT: a simple design demonstrating how passive weight versus a relatively light end with greater leverage might be used to create an over-unity effect.
