Patents of invention cover a vast range of ideas, from the industrial and agricultural revolutions, to transport, domestic life and health. Many are bizarre, and some are even horrific, but they all have a fascinating story to tell. The specifications are the written descriptions of how the invention will work, with drawings where appropriate. This talk focuses particularly on the drawings, while explaining the process of enrolling the specifications themselves and exploring a remarkable range of inventiveness.
