ABSTRACT:
Disclosed is a bar-tumbler type safety lock, as well as a key and a coding process for said lock. According to a single-key-entry embodiment, this lock comprises a body, a two-piece washer, a latch holder and a barrel having recesses in which notched tumblers can slide and which is maintained rotatingly and removably toward the front of said body by a stud and a stopping finger retained in two annular slots made radially in this body and which can be retracted by the introduction of a special extraction key into the lock; the coding of the lock is obtained by the forming, in the annular washer-assembly groove, of notches simultaneously in each of the tumblers by a conventional turning process, with the key inserted.
