  By its very purpose, the way that a lock mechanism works has to remain hidden from view and it is not easy to imagine what is happening inside. These three ingenious paper models of a combination lock, a mortice lock, and a 'Yale' style of barrel lock cover three main types. Also, there is an interesting minibook describing the historical development of lock design and possibilities for the future.
