Is there a mechanical way of increasing angular movement?

[Model12]

(A) being a common pivot point for (B) and (C). In relationship to (A), I would like to have (C) move twice the DEGREE OF ANGULAR movement as (B).

Any suggestions or thoughts on how I might accomplish this would be GREATLY APPRECIATED!

I believe that if you increase the centripetal acceleration at point C then it will move at a higher angular velocity.
someone please correct me if I'm wrong.

How about an epicyclic gear system? A is the centre of the sun gear, B is the centre of a planet gear, and C a point on an annular ring gear running on the planets?

You just described a simple gear joint. Just keep the relation D_AC = 2D_AB

Thanks for the suggestions. While I understand the concept, I'm looking for a mechanical method of rotating (C) twice that of (B) when both are connected to (A). Wondering if I need to consider some sort of a "cam-type" linkage or, possibly, a mechanical link to a secondary pivot point?

Thanks again..
