Created by Eli Whitney's ( creator of the cotton gin ) nephews, Eli Whitney and Philos Blake, a mortise lock (also mortice lock in British English) is one that requires a pocket - the mortise - to be cut into the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are generally found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States.
