Summary

Linus Yale invented a door lock with a cylindrical rim and pistons that are pressed inward by springs, and a revolving cylinder with radial apertures and pistons that can be driven back by a key, allowing the bolt to be locked and unlocked. The lock has a complex mechanism with multiple pistons of different lengths, making it difficult to pick. The key has wedge-shaped cavities and a cog that enters a corresponding cavity in the tumbler. Yale also modified the construction of the tumbler and bolt to dispense with the cog on the key and the arm on the tumbler, instead using a pin on the tumbler that works in a groove on the bolt to throw it horizontally.
