Abstract

A LEVER LOCK INCLUDES AN ADDITIONAL ARRESTER MEMBER (16) TO RESTRICT THE MOVEMENT OF A BARREL-AND-CURTAIN MEMBER (11) IN SUCH A WAY THAT, IN THE LOCKING CONDITION WITH THE BOLT (3) EXTENDED, THE BARREL- AND- CURTAIN MEMBER (11) CONNOT BE TURNED TO THE EXTENT WHICH WOULD ENABLE THE BARREL SLOT (13) TO FACE THAT REGION OF THE LEVER BELLIES (10) FROM WHICH INFORMATION ON THE KEY BIT PATTERN MIGHT BE DERIVED BY OBSERVATION OF THE PATTERN OF WEAR. THE ARRESTER MEMBER (16) IS IN THE FORM OF A PLATE SLIDING IN PARALLEL WITH THE BOLT (3) AND LINKED TO IT THROUGH A LOST- MOTION PIN AND SLOT COUPLING (18/19). WHEN THE BOLT (3) IS BEING RETRACTED BY THE CORRECT KEY (24) THE ARRESTER MEMBER (16) IS ALSO FREED FOR RETRACTION AND IS DRIVEN BACK BY ABUTMENT WITH THE TURNING CURTAIN PORTION (14). SUBSEQUENT RETURN MOVEMENT OF THE ARRESTER MAMBER (16) WHEN THE BOLT (3) IS EXTENDED OCCURS THROUGH THE PIN AND SLOT COUPLING (18/19). (FIG. 1)
