Abstract: A lock has a drive member which is moved to actuate the lock. A plurality of elongate members are connected to the drive member, one end of each elongate member being inserted in a respective spring-biased plunger. A first contoured element locates the plungers in position. An appropriate key must be inserted with a contoured surface in contact with a second set of plungers to align passages in the second set of plungers with the ends of the elongate members to enable the elongate members to move, thus permitting the lock to be opened.

Abstract: A key operated lock having a handle member slidably and rotatably operating within a rose member secured in a door, the rose having a bore therethrough in which a lock cylinder is rotatably mounted but restrained against axial displacement and has an axially displaceable and rotatably mounted latch actuator operably engageable with the handle by a key insertable into the handle transversely to the rotational axis. The lock cylinder has fixed wards extending toward the handle and key member which in the proper position of the key are in alignment with holes in the key which permit interlocking of the handle via the key with the lock cylinder for simultaneous rotation.
