A door mechanism pulling a door closed for latching. A puller tongue is triggered to release when adjacent a strike plate or jamb of a door. The puller tongue pushes the door completely closed resulting in latching. A setting lever is rotated upon turning a door knob setting the puller tongue in a retracted position. A raising lever and pendulum selectively cause the releasing of the puller tongue when the latch contacts a strike plate or jamb of a door and prevents releasing of the puller tongue when a door knob is turned. A door is caused to securely latch even though the door is closing slowly and with little force.
