Explanation: One possible alternative. Here is the OED definition:
An instrument for the mechanical copying of a plan, diagram, pattern, etc., on the same or an enlarged or reduced scale. In 17th c. called parallelogram.
It consists of four rods, perforated at uniform distances, and jointed together, two opposite joints being terminal and constant in position, the other two capable of being shifted according to the scale desired; one of the free ends carries a tracing-point, and one of the terminal joints a similar tracing-point; when one of these points is moved over the lines of the diagram, etc., the other traces the copy required.
