Abstract: A locking arrangement for doors and the like comprising a key-operated cylinder lock mounted in the door or the like and extending at both surfaces, to be operated by a key, an actuating gear keyed to the cylinder of the lock, which by means of a gear wheel and curved links is adapted to move at least one elongated bolt linearly.

Abstract: A door lock having two escutcheon plates clamped against the sides of a door, two mortise cylinders mounted in coaxial relation in the escutcheon plates and each having a rotatable key plug and an actuating arm on the inner end of the plug, a bolt slidable between extended and retracted positions, and a toggle joint bolt-operating mechanism actuated by the actuating arms on the key plugs. This mechanism includes a bolt link pivotally connected to the inner end of the bolt, and an actuating link between the ends of the key plugs having abutment means for coupling and uncoupling of the arms and the actuating link which is urged in toward the locked and unlocked positions by a toggle spring movable into oppositely over-center positions. The abutment means comprise two spaced tabs defining a slot into which the actuating arm is eccentrically extended and retracted during rotation of the key plug through full locking and unlocking revolutions.

Abstract: A casket lock structure for securing a casket top in a closed and sealed position. An elongated lock bar is slideably mounted inside the front of a casket. A connecting bar is pivotally mounted at one end to the lock bar and at the other end to an offset portion of a shaft extending through the wall of the casket such that rotation of the shaft causes a lateral translational movement of the lock bar. Striker pins fastened to the casket top are adapted to engage hook portions formed into the lock bar as the top is closed.
