Gate Latch. (fig. 73.) a b is a bolt for screwing into the gate post, and c d e a bolt for screwing into the gate. In shutting, the cylindrical iron or bolt e strikes against the party of the latch f g h, which, being jointed at i, is moved through an opening in the plate into the position of the dotted lines k; l, until, on the bolt passing, it resumes its place by its own weight; and, the part n of the latch m n o opposing further progress, the bolt remains fixed; and vice versa in shutting from the other side. In opening, the proper latch can easily be raised by the hand or a whip-handle, &c. This kind of latch is found very convenient for common field gates, and does not soon get out of order.
