Cool

Thanks.

Google Images "linear motion linkages"

There are some "straight line" mechanisms described in the following document that look to me very similar to your mechanism in this scene but, not being an M.E. I'm not certain if they translate movement exactly like yours. Might be worth taking a look.....

Thanks. I spent a couple hours checking both of those links out. I couldn't find the same linkage that's in this scene but suspect that the linkage would be obvious to "A person having ordinary skill in the art" (patent wise) since it's made of two common linkages.
