ABSTRACT:
A lock has a rotatable member (24), a latch member (22) operatively connected to the rotatable member for movement between locked and unlocked positions when the rotatable member is turned, a key stop (38) having an end facing toward an exposed end of a casing (10) that defines, together with the end of the rotatable member facing toward the exposed end of the casing a dead-end wall. Key stop (38)is mounted for axial reciprocation in, and for combined rotation with rotatable member (24) and has in the end facing toward the exposed end at least one code socket (46, 48) offset with respect to the axis of rotation of the rotatable member. The lock also has a rotatable spring-loaded block (54) mounted between the exposed end of the casing and the end of the key stop. The block is held in the casing against axial movement and has a substantially diametrical key slot (72) angularly offset with respect to the code socket. The key stop is axially pressed against the rotatable block by a spring (42).
