Abstract: There is disclosed a door latch mechanism having a sliding latch mounted to slide from a retracted position to an extended position in which it is adapted to engage in a keeper slot to hold the door closed. A pivoted actuator for the latch is adapted to engage a striker during closing of the door to retract the actuator. When the actuator is retracted it retracts the latch. A manual operator for retracting the actuator is operable from the inside or outside of the door. A locking member prevents retraction of the sliding latch to lock the door.

Abstract: A latch mechanism for storm doors, screen doors and the like. A pivoted latch is movable to and from an operative position in which to engage a keeper to maintain the door closed. The latch is moved away from operative position by a pusher assembly. When the door knob is turned, cam surfaces between the door knob and pusher assembly effect movement of the pusher assembly necessary to move the latch away from operative position.

Abstract: A latch and lock mechanism having a pivoted latch and means for retracting the latch. A dead bolt is also provided. A rotatable bolt actuator has a pin and slot connection with the bolt to move the bolt to its extended, locking position. The bolt actuator also has means for simultaneously blocking retraction of the latch to provide in effect a double dead bolt lock.

Abstract: A door latch for storm and screen doors having pre-drilled bolt receiving openings therein by which the latch housing are secured to opposite sides of the door. One of the latch housings has a plurality of openings therein and the other housing has a pair of inserts each having an inwardly extending internally threaded mounting post adjacent one end thereof and projecting through one of the openings in the door for receiving a threaded bolt inserted through an aligned opening in the other housing. The inserts are reversible end-for-end to vary the spacing between the mounting posts thereby to adapt the latch for use on doors having differently spaced bolt openings therein.
