ABSTRACT:
A locking arrangement for double gates whereby one or both gates may be conveniently locked against opening. The arrangement uses an extended vertical bolt on one gate and a conventional type latching bar on the other. A latch plate is adapted to receive a projection at the top end of the bolt and the latching bar for the purpose of retaining both in a locked condition using a single lock or just the projection for retaining only the bolt in a locked condition. A lock mechanism on each side of the gates is adapted to actuate a mechanism for retaining the latching bar and/or projection in the latch plate. The arrangement allows one gate to be unlocked for pedestrian traffic while the other is locked to prevent passage of large articles through the gates.
