If Lenard had been just a little bit madder & thought of
a windmill powered repeating catapult with flywheel auxiliary
power for if the wind drops it might have looked like this.
With a windmill beside it.
And a really big flywheel beside that.
Rather than a fixed
armature that has to be pulled back
between shots it has a sliding one that passes through the
with a bucket on both ends.
Further design specifications may be needed.
May not work as advertised.
May not work.
The armature slides through the centre axis so that the short
end passes under the body of the machine (scooping up the
payload as it does) while the long end sweeps majestically
overhead to send its payload hurtling through the sky.
For demonstration purposes we'll be using custard pies but a
range of unsuitably dangerous payloads are available from the
gift shop at very reasonable rates.
