This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.

This did not affect the fundamental principle but it allowed the engine room to be smaller because the linkage was more compact. [2] The Newcomen engine's piston was propelled downward by the atmospheric pressure.
Example of a void pantograph pattern before (left) and after (right) the document has been photocopied. In security printing, void pantograph refers to a method of making copy-evident and tamper-resistant patterns in the background of a document. Normally these are invisible to the eye, but become obvious when the document is photocopied.
