Its difficulties were minimized, how ever, by the invention of a mechanical device whereby eighteen fountain pens were connected on the principle of the pantagraph in such a way that all moved in unison with a pen in the hand of a secretary, who thus signed nineteen certificates at once.

Here no new principle was involved, but the ingenious application of an old principle resulted in a great saving of time and labor.
