“But around the time of strike, I would expect a free mass to move outwards
under centrifugal force, rather than downwards under gravity. “

Which I believe is what happens.  The toggle is thrown outwards by centrifugal force as the bell rotates – this allows the clapper to strike the bell.  The clapper bounces but by now the bell has slowed down and is nearer the vertical.  The toggle drops down and as the clapper tries to return to the bell it is prevented by the toggle – thus allowing the bell to hum.  I have some of the bits at the back of my garage – it seemed unnecessary to drag another few pounds of metal through a peal so I removed the defunct mechanism!
