Blish lock
The Blish Lock is a breech locking mechanism designed by John Bell Blish based upon his observation that under extreme pressures, certain dissimilar metals will resist movement with a force greater than normal friction laws would predict. In modern engineering terminology, it is an extreme manifestation of what is now called static friction, or ''stiction''. His locking mechanism was used first in the Thompson submachine gun. == Invention ==
The Blish Lock resulted from Blish's observation of large naval guns. He noticed that the breech blocks of naval guns with interrupted thread breeches remained closed when fired with full charges, but tended to unscrew when fired with light charges. He concluded that dissimilar metals have a tendency to adhere to each other when subjected to very high pressure. This principle of metallic adhesion of dissimilar metals became known as the Blish Principle. Blish put this knowledge to use in a delayed-blowback breech lock. He developed a working model that used a simple wedge as the lock, and was eventually assigned on March 9, 1915.
