Pantograph

Pantograph, << PAN tuh graf, >> is the name of a mechanical drawing instrument which copies, traces, or cuts in duplicate a design, map outline, or drawing. It is made of four bars or rods held together by adjustable pins. One end of the pantograph is held stationary. One tracing point is moved over the design to be copied, following its outlines. Another point will then move in unison with this point, copying or cutting a duplicate outline. The pantograph can be set, by using adjustable pins, to copy in any size.
