Abstract: A door lock for attachment to a door which can move into a position adjacent to a jamb having a door strike. The lock includes a support member formed from a pair of spaced, generally parallel sides and an end wall interconnecting the sides. The sides and end wall are adapted to enclose a recess cut in the edge of the door. A shiftable lock bolt is carried between the sides and movable through an opening in the end wall and into locked relationship to the door strike when the door is in a closed position.

Abstract: A door lock including a support member formed from a pair of spaced, generally parallel sides and an end wall interconnecting the sides. A shiftable, spring biased lock bolt is carried between the sides and movable through an opening in the end wall and into locked relationship to a door strike when the door is closed. Several embodiments of the structure for moving the lock bolt away from the door strike are disclosed including the following: a rotatable shaft having a knob at each end and provided with a projection extending into a recess in the lock bolt; a pair of L-shaped levers pivotally mounted on respective sides of the support member and having respective pins in respective slots of the door lock bolt; and a shiftable plate projecting laterally from the sides of the support member and having a pin received within a camming slot through the lock bolt.
