Nice design. Do you have pictures or video of it in operation (i.e., lifting balls)?
I'm not sure that "new" is entirely accurate, though it may very well be new to you.
K'nex has it in lesson 192 of their Teachers' Guides. It's also included in the K'nex "Exploring Machines" schools kit. And there's even a You Tube video of someone else's design.
