Abstract
There is disclosed a Bramah lock which comprises locking lever bars mounted for longitudinal displacement and rotation, said bars having each two cuttings, thereby providing the lock with a double safety device as long as the bars are not actuated by the key to their unlocked position. The lock is therefore a double security lock offering an increased resistance to unauthorized attempts to pick it and a larger number of combinations.
