Keeping with the theme of last Thursday’s launch of the Safe Deposit page of the Library, here are some of the earliest safe deposit box and lock patents. You can see a lot of the progression of both safe deposit boxes and locks by clicking through these patents chronologically. These patents were pulled directly from Lock & Lockmakers of America by Thomas F. Hennessy. If you don’t already have a copy of Lock & Lockmakers of America, grab a copy; it will be one of the most referenced books in your library.
