Re: Name of arm that moves in vertical plane?
Can you sketch it out? Your description is a bit confusing to me, since it sounds like that's what a four-bar (parallelogram) linkage does.

Re: Name of arm that moves in vertical plane?
This is a very crude sketch but it is everything I can remember. I think there might have been two fixed points on the joint mechanism, which is what the green dots represent. The red line shows that the end point of the arm always stays in the same vertical plane. A four-bar mechanism will not do this as it makes an "arc" as it is raised from the lowest to highest point.

It's a Peaucellier-Lipkin linkage.

Re: Name of arm that moves in vertical plane?
And for a different perspective, there are the models that demonstrated the theories of Franz Reuleaux - link - 39 of which are straight (or almost straight) line motion.
