Abstract
In a cantable latching plate type of door-closer latch, a backing plate is located at the side of the latch plate opposite the door-closer cylinder. Spring fingers normally hold the latch plate against the backing plate in unlatched position. A latch-setting cord extends from the backing plate to a location remote from the door-closer latch mechanism that can be pulled to shift the backing plate toward the door-closer cylinder for canting the latch plate relative to the door-closer piston rod into latched position.

- 2. Remote setting-control mechanism for a door-closer latch for a door closer mounted on the upper margin of a door having hinge means supporting an edge portion of the door for swinging of the door about an upright axis and the door closer including a piston rod, such latch including a plate having an aperture through which the piston rod projects and tiltable relative to the piston rod into canted jammed latched position relative to the piston rod, the improvement comprising control means for effecting setting of the latch plate in canted latched position relative to the piston rod including a pull cord and means guiding said pull cord across the upper margin of the door away from the hinged edge of the door and downward along the swinging edge of the door.
- 4. Control mechanism for an apertured latch plate of a door closer having a piston rod extending through such latch plate aperture comprising backing means carried by the door closer, spaced from the door closer and located adjacent to the latch plate, and moving means for shifting said backing means relative to the latch plate for effecting setting of the latch plate in canted latched position relative to the piston rod.
