I saw this on you tube but it was a little different

you may not know this but that has been used by the knex company but this can be used as a lift:-)

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.
