  • Patent number: 4178025
    Abstract: The illustrated gate latches include an anchor plate and a latch plate. The latch plate is pivotally mounted relative to the anchor plate by means of a screw which also serves to hold the anchor plate in place. The anchor plate is shown to include one or more alignment flanges, one or more nailing points, and means to limit pivotal movement of the latch plate such as a pair of pivot stop flanges, all formed integral with the anchor plate. The latch plate includes a cam surface which cooperates with a detent bar to pivot the latch plate until the bar is located within a detent gripping or latching section, allowing the latch plate to pivot in the opposite direction and temporarily fix the bar and the latching plate to one another. The trailing end of the latching plate cooperates with the pivot-stop abutments to limit the pivotal movement of the latching plate in one embodiment. A pin and slot arrangement is employed for the same purpose in a second embodiment.

  • Patent number: 4062575
    Abstract: A gate latch in which a locking bolt is located so as to extend through vertical guides at the opposite ends of a latch body. A keeper is mounted on the latch body at the end thereof distal from the free or latching end of the bolt and an offset portion of the bolt is located so as to be slidable along the keeper. Additionally, the bolt is pivotable about its line of contact with the keeper so that the gate may be latched and unlatched. The keeper is provided with a deformation resembling an S-shaped curve in the horizontal plane to provide obstruction to the free sliding of the bolt and thus prevent inadvertent movement thereof.

  • Patent number: 3997945
    Abstract: The illustrated embodiment discloses a compressive force application device, which might be used on a gate to prevent sagging thereof, including a plate having eyelets therein through which the tensioning cord or cable may be threaded so that it adjoins itself; thus, the threaded relationship is maintained by the cable's frictional contact with itself.
