Abstract

A LOCK HAS A SWINGING BOLT 4 DEADLOCKED BY A STUMP 8 ON A SLIDE 6 BLOCKED BY A LEVER PACK 10. THE LEVERS 10 ARE ALL IDENTICAL, DIFFERING IN THEIR REQUIRED LIFTS BEING OBTAINED BY DIFFERING THEIR POSITIONS OF ENGAGEMENT ON A PIN 11, EACH LEVER HAVING A THREE-CELLED HOLE 18 BY WHICH IT CAN BE BORNE ON THE PIN 11 AT THREE DIFFERENT HEIGHTS. TO CHANGE THE CODING OF THE LOCK THE EXISTING CORRECT KEY IS USED TO SET THE LEVERS AND DRAW THE STUMP 8 INTO THE GATES 13. THE PIVOT PIN 11 IS THEN USCREWED FROM THE LOCK TO LEAVE THE LEVERS FLOATING ON THE STUMP 8. THE NEW KEY TO PASS IS THEN INSERTED AND TURNED TO SCRAMBLE THE LEVERS FOLLOWING WHICH THE PIVOT PIN 11 IS REPLACED, THE LATTER NOW ENGAGING IN DIFFERENT ONES OF THE CELLS OF THE LEVER HOLES 18 APPROPRIATE TO THE LIFTS SET BY THE NEW KEY.
