RE: A secure way to move cash….in 1909
Once the ball is thrusted up to the top of the tracks, it moves surprisingly fast, keeping the momentum with gravity. The track is fairly long, very satisfying to watch such precision and movement.
Thanks for explaining it.
I really like these mechanical solutions from the past. It must have been very difficult to design the system.
Particularly without CAD, perhaps it was first rudimentarily designed and then perfected with trial and error.
